Description

  The present invention relates to an anode straightening device.

  As a method for producing a high-purity metal, there is electrolytic smelting. In this electrolytic smelting process, the anode (electrode made of a target metal having a low purity or an electrode that does not elute into the electrolyte) and the cathode are alternately immersed in an electrolytic bath filled with the electrolyte and energized, so that the cathode Products are manufactured by electrodepositing high-purity metal on the surface of the seed plate. Since a large amount of electric power is consumed in such an energization process of electrolytic smelting, it is required to reduce power consumption in order to improve the production efficiency of electrolytic smelting.

  In order to reduce power consumption in electrolytic smelting, the anode and the cathode are arranged in the electrolytic cell so that the distance between them is a distance suitable for electrodeposition. However, if the distance between the anode and the cathode changes from an appropriate distance, the power consumption changes under the influence of the change in the distance. For example, when the distance between the anode and the cathode becomes too large, the electric resistance of the electrolytic solution increases and a large amount of power is required for electrodeposition. On the other hand, if the distance between the anode and the cathode becomes too small, the power consumption can be reduced, but if electrodeposition proceeds on the cathode seed plate, a part of the electrodeposited metal may come into contact with the anode. is there. If such a contact occurs, current will flow directly from the anode to the cathode, thus wasting power. Therefore, in order to reduce power consumption and prevent the waste of electric power and the like from occurring, it is necessary to appropriately maintain the distance between the anode and the cathode in the electrolytic cell.

  Both the anode and the cathode are held by a bus bar which is an electrode provided on the upper part of the electrolytic cell, and are suspended in the electrolytic cell. For this reason, the perpendicularity of both electrodes affects the distance between the anode and the cathode in the electrolytic cell. That is, since the vertical strain of both electrodes has an effect, it is important to reduce the strain of both electrodes.

  By the way, the anode A is manufactured by casting so as to have a shape as shown in FIG. That is, the main body part B and a pair of ear parts C, C provided on both sides of the upper part of the main body part B are integrally cast. The pair of ears C, C of the anode A serves as a support part for suspending the anode A when the anode A is immersed in the electrolytic cell, and also functions as a contact point with the bus bar. Therefore, in order to suspend the anode A in a stable state while maintaining good contact with the bus bar, cutting is performed so that the lower portions of the pair of ear portions C and C are flat.

  However, the mold for casting the anode A has a slight gradient or step on the inner bottom surface of the mold in order to facilitate the peeling of the anode. For this reason, the position of the pair of ears C, C of the anode A is, in the thickness direction of the anode A, from the back surface side (the surface side in contact with the bottom of the mold) to the front surface side (the molten metal surface side in the mold). It is formed at a slightly biased position. Specifically, as shown in FIG. 5, the pair of ears C and C of the anode A is shifted to the surface side from the center lines X and X ′ passing through the center of gravity G of the main body B of the anode A. For this reason, even if the lower part of the pair of ears C, C is cut flat, when the anode A is inserted into the electrolytic cell, the anode A swings around the point P as a fulcrum. The posture is changed so that the surface including the contact points P, P and the center of gravity G faces the vertical direction (see FIG. 5). In other words, the anode A changes its posture so that its surface is inclined with respect to the vertical direction. Then, when the anode A is immersed in the electrolytic cell, the lower end of the main body B of the anode A has a shorter distance to the cathode on the front side (left side in FIG. 5) than the upper end. (Right side in FIG. 5) becomes long. That is, even if the anode A is immersed in the electrolytic cell so that the distance to the cathode is appropriate in the upper part of the electrolytic cell, the distance between the anode A and the cathode is shifted in the lower part of the main body B (that is, in the electrolytic cell). . Then, the contact between the anode A and the cathode as described above may occur, and the production efficiency of electrolytic smelting may decrease.

  Therefore, in order to correct the deviation between the pair of ears C and C of the anode A, that is, the deviation with respect to the center lines X and X ′ passing through the center of gravity G of the main body B of the anode A, the anode A can be pressed. (For example, Patent Documents 1 to 3 and the like).

  Specifically, a pair of ears C, C are pressed and bent toward the back side by pressing, and a point P where the ears contact the bus bar is a center line X passing through the center of gravity G of the main body B of the anode A, Corrected to overlap X '. If corrected in this way, when the anode A is inserted into the electrolytic cell, the surface including the points P and P where the pair of ears C and C come into contact with the bus bar and the center of gravity G is oriented close to the vertical direction. Therefore, it is possible to prevent the anode A from being inclined when the anode A is immersed in the electrolytic cell.

Japanese Patent No. 318496 Japanese Patent No. 4282175 Japanese Patent No. 5555937

  However, when the pair of ears C and C of the anode A is pressed as described above to appropriately adjust the positions of the pair of ears C and C, the thickness of the pair of ears C and C is changed. For example, the amount of pressing the pair of ears C and C must be changed. For this reason, according to the thickness of the anode A (that is, the thickness of the pair of ears C and C), the deformation amount of the pair of ears C and C at the time of pressing must be adjusted.

  Conventionally, the amount of deformation of the pair of ears C, C has been adjusted by changing the thickness of the receiving mold located on the back side, but in order to change the thickness of the receiving mold, the receiving mold is changed each time. It is necessary to remove and install. The change of the receiving mold requires about 25 to 30 minutes, and the facility must be stopped while changing the receiving mold. On the operating day of the equipment, even if it is about 25 to 30 minutes, if the equipment is stopped, the influence on other processes is great. Therefore, the change of the receiving mold is performed on the day when the equipment is not operated. However, since the thickness of the anode A including the pair of ears C and C varies by about 5 mm or less depending on the day when the anode A is manufactured, the receiving die was changed only on the day when the equipment is not operated. Then, it is difficult to appropriately adjust the deformation amount of the pair of ear portions C and C.

  On the other hand, as in Patent Document 1 described above, if the receiving die is provided so as to be movable, it is possible to adjust the deformation amount of the pair of ear portions C and C while operating the equipment. However, since a very large pressing force is generated when pressing the pair of ears C, C, the moving mechanism for moving the receiving mold does not move the receiving mold even if a large pressing force is applied to the receiving mold. A function to hold in a predetermined position is required. For this reason, since the moving mechanism for moving the receiving mold becomes complicated or large, the facilities are also enlarged. In addition, in the existing equipment, since it is necessary to secure the transport path of the anode A, there is little surplus space around the device for pressing the pair of ears C, C of the anode A, and the receiving mold is substantially used. It is difficult to install a moving mechanism for movement.

  In view of the above circumstances, an object of the present invention is to provide an anode correction device that can easily and quickly correct the ear portion of the anode without increasing the size and complexity of the equipment.

An anode straightening device according to a first aspect of the present invention is a device for straightening an anode used for electrolytic smelting, and a reference block that comes into contact with the back surface of the ear of the anode, and a pressurization provided so as to be close to and away from the reference block.

And a function of adjusting the amount of movement of the pressure block.

According to the first invention, since the deformation amount of the ear portion can be adjusted only by changing the thickness adjusting member, the deformation amount of the ear portion can be adjusted easily and quickly. Therefore, even on the operating day of the facility, the amount of deformation of the ear portion can be adjusted, and the verticality of the anode can be improved.
According to the second aspect of the present invention, the contact member can be easily positioned with respect to the contact surface by inserting the insertion member of the fixed portion into the recess of the block body.

According to the fourth aspect of the invention, the contact member can be more accurately positioned with respect to the contact surface, so that the thickness adjusting member can be installed easily and quickly.
According to the fifth aspect of the present invention, since the contact member can be surely disposed at a predetermined position with respect to the contact surface simply by inserting the insertion member of the fixed portion into the recess, the thickness adjusting member can be easily installed. Can be done quickly.

  The anode straightening device of the present invention is a device that deforms and corrects the ear portion of the anode by pressing, and is characterized in that the amount of deformation of the ear portion can be adjusted quickly and easily. ing.

(Anode A)
First, before describing the anode straightening device 1 of the present embodiment, the configuration of the anode A will be briefly described.

  The anode A is used for electrolytic purification, and the anode A includes a main body B and a pair of ears C and C (see FIG. 4). The anode A is immersed in the electrolytic solution in the electrolytic cell while the pair of ears C and C are suspended from the electrolytic cell, and is subjected to electrolytic purification.

  The anode A is cast by pouring molten metal such as copper or bismuth into a mold. The casting mold for casting the anode A has a slight slope on the inner bottom surface in order to facilitate the removal of the anode A. Therefore, the anode A has a pair of ears C, C in the thickness direction of the anode A, from the back surface side (the surface side in contact with the bottom of the mold) to the front surface side (the molten metal surface side in the mold). It is formed at a slightly deviated position. Specifically, as shown in FIG. 5, the pair of ears C and C of the anode A is shifted to the surface side from the center lines X and X ′ passing through the center of gravity G of the main body B of the anode A. Then, when the anode A is suspended from the electrolytic cell by the pair of ears C and C, the plane including the points P and P where the pair of ears C and C and the bus bar are in contact with the center of gravity G is on the vertical line. The anode A swings so as to be positioned, and the front surface and the back surface of the main body B of the anode A are inclined with respect to the vertical surface. Therefore, the anode correction device 1 of the present embodiment corrects the pair of ears C and C by pressing and bending the pair of ears C and C toward the back side. In other words, when immersed in the electrolytic cell, the anode P of the present embodiment is such that the point P where the pair of ears C, C and the bus bar come in contact with the center lines X, X ′ passing through the center of gravity G of the anode body. The correction device 1 corrects the pair of ears C and C.

(Anode straightening device 1 of this embodiment)
As described above, the anode correction device 1 of the present embodiment corrects the pair of ears C and C.

  The anode correction device 1 has a function of correcting not only the pair of ears C and C but also the bending of the main body B. Similarly to the correction of the ears C and C, the correction of the main body B is the main body reference block 21 that comes into contact with the back surface, and the main body pressure block 25 provided so as to be able to approach and separate from the main body reference block 21. Implemented by: That is, the main body pressing block 25 presses the main body B toward the reference block in a state where the anode A is arranged so that the back surface of the main body B is a predetermined distance from the contact surface of the main body reference block 21. . Then, the main body part B is corrected by being sandwiched between the main body part pressure block 25 and the main body part reference block 21. In addition, the mechanism in which the main-body-part pressurization block 25 approaches and separates with respect to the main-body-part reference block 21 is not specifically limited. For example, a cylinder mechanism such as a hydraulic cylinder (reference numeral 26 in FIG. 4), a screw mechanism, a diaphragm mechanism, or the like can be employed.

  Further, the shapes of the main body reference block 21 and the main body pressure block 25 are not particularly limited. Each contact surface in contact with the anode A may be a flat surface so long as the main body reference block 21 and the main body pressure block 25 do not easily bite into the anode A after pressing. For example, it may be formed in a cube or a rectangular parallelepiped, or may be a cylinder having a flat contact surface.

  As shown in FIG. 1, the anode straightening device 1 of the present embodiment includes anode holding portions 2 and 2 in which an anode A to be straightened is disposed, a reference block 10 fixed to a frame 3 of the device, and the reference block. And a pressurizing block 15 provided so as to be close to and away from 10.

  The anode holding part 2 suspends and holds the anode A. Specifically, the anode holding portions 2 and 2 are configured such that a pair of ear portions C and C of the anode A to be corrected are placed on the upper surface thereof, and the anode A is suspended and held. The anode holding portions 2 and 2 may be provided so as to have the above functions, and the structure is not particularly limited. For example, the anode holding portions 2 and 2 can be formed by rod-shaped members that are installed so that the upper surfaces thereof are horizontal. Alternatively, it may be received by a U-shaped member or received by a mechanism such as a vise.

  In a state where the anode A is held by the anode holding unit 2, the reference block 10 and the pressure block 15 are arranged so as to sandwich the anode A. Specifically, the reference block 10 is arranged on the back side of the anode A (right side in FIG. 1), and the pressure block 15 is arranged on the front side of the anode A (left side in FIG. 1). Has been. A pressure block moving mechanism 16 that moves the pressure block 15 closer to and away from the reference block 10 is provided.

  For this reason, as shown in FIG. 2, if the pressurizing block 15 is moved toward the reference block 10 by the pressurizing block moving mechanism 16, the pair of ears C and C are moved by the pressurizing block 15. (FIG. 2B). Then, the pair of ears C and C can be corrected by being sandwiched between the pressure block 15 and the reference block 10.

  For example, if the thickness of the main body B of the anode A is 40 mm and the thickness of the ear C is 38 mm, the thickness of the reference block 10 is made about 1 mm thinner than the thickness of the main body reference block 21 of the main body B. Then, by correcting the pair of ear portions C and C, when the anode A is suspended from the bus bar by the pair of ear portions C and C, the anode A can be moved onto the center line XX ′ of the main body portion B. it can.

  If there are two pressure blocks 15 and two reference blocks 10, the pair of ears C and C can be corrected independently. In this way, even when only one ear C is displaced to the surface side from the center lines X and X ′ passing through the center of gravity G due to the inclination of the mold during casting of the anode A, The positions of the ears C and C can be made appropriate.

  The configuration of the pressure block moving mechanism 16 is not particularly limited as long as the pressure block 15 can be moved closer to and away from the reference block 10. For example, a cylinder mechanism such as a hydraulic cylinder (reference numeral 16 in FIGS. 1 and 2), a screw mechanism, a diaphragm mechanism, or the like can be employed.

  The pressure block moving mechanism 16 may be provided in each pressure block 15, or a plurality of pressure blocks 15 may be moved by one pressure block moving mechanism 16. In particular, if the output of the pressurizing block moving mechanism 16 is sufficient with respect to the strength of the anode A, all of the pressurizing blocks 15 for pressing the pair of ear portions C and C are replaced with one pressurizing block moving mechanism 16. It is also possible to drive with. If it does in this way, the time slot | zone which corrects a pair of ear | edge parts C and C will become substantially the same. Then, even if there are fluctuations in hydraulic pressure or voltage for driving the pressurizing block moving mechanism 16, vibration of the anode, etc., there is an excess or deficiency in the correction amount of the pair of ear parts C, C due to the influence. An anode having substantially the same value as C is obtained. Such an anode A can be easily corrected when correcting the pair of ears C and C again.

  The shape of the block main body 11 and the pressure block 15 of the reference block 10 described above is not particularly limited. The contact surface that contacts the anode A may be a flat surface as long as the reference block 10 and the pressure block 15 do not easily bite into the anode A after pressing. For example, the block main body 11 and the pressure block 15 may be formed in a cube or a rectangular parallelepiped, or may be a cylinder having a contact surface formed on a flat surface.

  In addition, the contact surface in the block main body 11 is a surface which contacts the anode A in the state which removed the thickness adjustment member 12 mentioned later. In other words, it is a surface located on the pressure block 15 side in the block body 11 (a surface facing the pressure block 15) (see FIG. 3).

(Reference block 10)
As shown in FIG. 1, the reference block 10 includes a block main body 11 as described above, and a thickness adjusting member 12 that is detachably provided on the block main body 11. The reference block 10 can adjust the thickness of the reference block 10, that is, the amount of deformation when the pair of ear portions C and C are pressed by the pressure block 15 by attaching and detaching the thickness adjusting member 12. It has become.

(Block body 11)
As shown in FIG. 1, the block main body 11 is a substantially rectangular parallelepiped block. The back surface of the block body 11 is fixed to the frame 3 of the apparatus so that the front surface (that is, the surface facing the pressure block 15, the contact surface described above) is substantially parallel to the contact surface of the pressure block 15. Has been.

On the upper surface of the block body 11, a groove-shaped recess 11h that is recessed from the upper surface is provided. The concave portion 11h is a groove provided in parallel with the contact surface of the block main body 11, and is formed so that the opposite side surface side can be seen from one side surface of the block main body 11. The width and depth of the groove-like recess 11h are not particularly limited. For example, if the width is 50 to 100% of the width of the block main body 11 and the depth is 0.1 to 50% of the thickness of the block main body 11, the thickness adjustment is performed while suppressing a decrease in the strength of the block main body 11. The member 12 can be stably attached.

(Thickness adjusting member 12)
As shown in FIG. 1, the thickness adjusting member 12 includes a contact portion 12a, an insertion member 12b, and a connecting member 12c.

  First, the insertion member 12b is inserted into the recess 11h of the block body 11 described above. This insertion member 12b is a plate-like member, and is formed so that the width thereof is substantially the same as or slightly narrower than the width of the recess 11h. That is, when the insertion member 12b is inserted into the recess 11h, the insertion member 12b is formed so as not to move or rattle in the width direction of the recess 11h (in other words, the thickness direction of the reference block 10). Yes. The length of the insertion member 12b (L in FIG. 1A) is equal to or slightly shorter than the depth of the recess 11h.

  One end of a connecting member 12c is connected to the upper end of the insertion member 12b. This connecting member 12c is also a plate-like member, and its lower surface is formed as a flat surface. This lower surface is provided so as to be orthogonal to the surface of the insertion member 12b. Therefore, when the insertion member 12b is inserted into the recess 11h, the connecting member 12c is provided such that the lower surface thereof is in surface contact with the upper surface of the block body 11.

  A contact member 12a is provided at the other end of the connecting member 12c. The contact member 12a is also a plate-like member, and the front surface and the back surface are formed on flat surfaces parallel to each other. Moreover, the surface of the contact member 12a is provided so as to be parallel to the surface of the insertion member 12b described above. That is, the thickness adjusting unit 12 is formed in a substantially U shape in a side view.

  The distance between the back surface of the contact member 12a and the front surface of the insertion member 12b is substantially the same as the distance W from the contact surface of the block body 11 to the front inner surface (the left inner surface in FIG. 1) of the recess 11h. It is provided as follows.

  Since the thickness adjusting portion 12 is formed in the shape as described above, if the insertion member 12b is inserted into the recess 11h, the contact member 12a is disposed in a state where the back surface thereof is in surface contact with the contact surface of the block body 11. The Then, the front surface (the surface on the pressure block 15 side) of the contact member 12a can be caused to function as a contact surface that contacts the ear portion C of the anode A.

  Further, if the thickness adjusting unit 12 is attached to the block main body 11, the thickness of the reference block 10 can be adjusted to a thickness obtained by combining the thickness of the block main body 11 and the thickness of the contact member 12a.

  And if the thickness adjustment part 12 from which the thickness of the contact member 12a differs is used, the thickness of the reference | standard block 10 can be changed. Then, since the deformation amount of the ear portion C can be adjusted only by changing the thickness adjusting unit 12, the deformation amount of the ear portion C can be adjusted easily and quickly. Therefore, if the reference block 10 is employed, the deformation amount of the ear portion C can be adjusted even on the operating day of the facility, and the verticality of the anode A can be improved.

  The thickness adjusting unit 12 can be attached to the block main body 11 if there is a space on the upper surface of the block main body 11 and there is a gap in which the contact member 12a enters from the block main body 11 to the pressure block 15 side. Therefore, it is possible to safely fix and replace the thickness adjusting unit 12. Specifically, the upper surface of the block main body 11 has a space enough for an operator and his / her arm to enter, and the thickness of the contact member 12 a of the thickness adjusting unit 12 is closer to the pressure block 15 than the block main body 11. If there is a gap of a certain degree, the thickness adjusting part 12 can be fixed to the block body 11 or exchanged.

  The insertion member 12b and the connecting member 12c described above correspond to the fixing portion referred to in the claims. In addition, a fixing | fixed part is not restricted to the above aspects, A various form can be employ | adopted. For example, a portion protruding upward is provided at the top of the block body 11. And you may form a fixing | fixed part in the shape which can be attached so that it may cover so that the protruding part may be straddled.

  Further, the thickness adjusting unit 12 may be fixed to the block main body 11 with a bolt or the like. For example, a hole that can fix a bolt or the like is formed in the upper surface or side surface of the block main body 11, and a fixing plate disposed on the upper surface or side surface of the block main body 11 is provided as a fixing portion. And the through-hole which can insert a volt | bolt etc. in the fixing plate is provided. Then, by inserting a bolt or the like into the through hole of the fixing plate and inserting the bolt or the like into the hole of the block main body 11, the thickness adjusting unit 12 can be fixed to the block main body 11. In this case, the thickness adjusting part 12 can be firmly fixed to the block body 11 by forming a female screw in the hole of the block body 11 and screwing a bolt or the like.

  Furthermore, a hole that can fix a bolt or the like is made in the contact surface of the block main body 11, and a through hole that can be inserted into the contact member 12 a of the thickness adjusting unit 12 is provided. Then, by inserting a bolt or the like through the through hole of the contact member 12 a and inserting the bolt or the like into the hole of the block main body 11, the thickness adjusting unit 12 can be fixed to the block main body 11. Also in this case, the thickness adjusting part 12 can be firmly fixed to the block body 11 by forming a female screw in the hole of the block body 11 and screwing a bolt or the like. In this case, it is necessary to provide a recess for accommodating the head of the bolt on the contact surface so that the head of the bolt does not protrude from the surface of the contact member 12a of the thickness adjusting member 12.

(Regarding the reference block 10)
In the above example, the case where the members 12a to 12c of the thickness adjusting unit 12 of the reference block 10 are formed of plate-like members has been described. However, the thickness adjusting unit 12 is not necessarily configured as described above.

  For example, it is good also as a structure which connected the plate-shaped contact member 12a to the rod-shaped insertion member 12b by the rod-shaped connection member 12c. Even in this case, if the insertion member 12 b is inserted into the recess 11 h of the block body 11, the back surface of the contact member 12 a is brought into surface contact with the surface of the block body 11. Then, the thickness adjustment part 12 can be functioned similarly to the case where each member 12a-12c is formed with a plate-shaped member.

  In the above example, the case where the recess 11 h of the block body 11 is provided on the upper surface of the block body 11 has been described. However, the recess 11 h may be formed on a surface other than the upper surface of the block body 11, that is, on the side surface or the lower surface of the block body 11. However, if the concave portion 11 h is provided on the upper surface of the block body 11, the thickness adjusting member 12 can be easily fixed. For example, even when the thickness adjusting member 12 is fixed to the block main body 11 with a bolt or the like, as long as the recess 11h is provided on the upper surface of the block main body 11, even if the operator does not hold the thickness adjusting member 12, The thickness adjusting member 12 is maintained in a state of being caught by the block main body 11. Therefore, the operator's work burden can be reduced when the thickness adjusting member 12 is replaced.

  Furthermore, although the case where the lower surface of the connecting member 12c is in surface contact with the upper surface of the block body 11 has been described in the above example, the lower surface of the connecting member 12c is not necessarily provided so as to be in surface contact with the upper surface of the block body 11. Also good. However, since the positioning of the contact member 12a of the thickness adjusting member 12 with respect to the contact surface of the block body 11 can be more accurately performed in this way, the thickness adjusting member 12 can be installed easily and quickly. The advantage that it can be obtained.

  In addition, you may correct by making the surface of the block main body 11 into a contact surface, without attaching the thickness adjustment part 12. FIG. In this case, it is possible to leave nothing in the recess 11h without leaving anything, but it is desirable to install the spacer 13 as shown in FIG. If the spacer 13 is provided, it is possible to prevent the block main body 11 from being deformed in the recess 11 h by the pressure applied from the pressure block 15.

(Movement adjustment)
If the reference block 10 as described above is used, the thickness adjustment unit 12 is not used, and the thickness adjustment unit 12 to be used (the contact member 12a having a different thickness) is used to obtain the ear portion. The amount of deformation of C can be adjusted.

  On the other hand, even when the reference block 10 as described above is used, when the deformation amount of the ear C is changed (or when the surface of the reference block 10 is worn), the thickness adjusting unit 12 is replaced. There must be. In addition, one thickness adjusting unit 12 cannot cope with various deformation amounts. Since the thickness of the ear portion C slightly changes for each anode A even on the same operation day, it is desirable to have the following movement amount adjustment function in order to finely adjust the deformation amount.

  In other words, the anode straightening device 1 of the present embodiment is provided with a thickness measuring unit that measures the thickness of the pair of ears C and C in the anode A before straightening. For example, a thickness measuring unit is provided with a non-contact type laser distance meter so that a pair of ears C, C in the anode A held by the anode holding unit 2 can be irradiated with laser from the front. It can be.

  The thickness measuring unit is not particularly limited as long as it can measure the thickness of the pair of ears C and C in the anode A before correction. In addition to the laser distance meter described above, measurement devices such as an ultrasonic distance meter and a digital caliper can be employed.

  Further, a moving amount adjusting unit that controls the operation of the moving mechanism that moves the pressure block 15 is provided. Then, information on the thickness of the pair of ears C and C measured by the thickness measuring unit is transmitted to the moving amount adjusting unit. In addition, thickness information of the reference block 10 currently installed is transmitted to the movement amount adjustment unit. The thickness information of the reference block 10 is information on the thickness of the block main body 11, the presence / absence of the thickness adjusting unit 12, and information on the thickness of the contact member 12 a of the thickness adjusting unit 12.

  If the movement amount adjustment unit as described above is provided, the deformation amount of the pair of ear portions C and C can be adjusted in accordance with the thickness of the pair of ear portions C and C of each anode A. Specifically, adjustments are made using the following mechanism. First, based on the measurement value of the thickness of the pair of ear portions C and C and the thickness information of the reference block 10, the thickness of the pair of ear portions C and C contacts the current contact surface of the reference block 10. It is assumed that the movement amount adjusting unit has grasped that the pair of ear portions C and C is deformed more than necessary when it is deformed. In this case, the movement amount adjustment unit reduces the movement amount of the pressure block 15 and reduces the deformation amount of the pair of ear portions C and C. Then, the deformation amount of the pair of ear portions C and C can be made suitable for the thickness thereof.

  For example, when the reference block 10 is provided so as to have an appropriate deformation amount when the thickness of the pair of ears C, C of the anode A is 38 mm, the actual thickness of the pair of ears C, C is as follows. Is 37 mm. In this case, if the pair of ears C and C are deformed until they contact the contact surface of the reference block 10, when the pair of ears C and C are suspended from the bus bar, The part to be shifted to the back side of 1 mm. That is, the pair of ears C and C is in an excessively deformed state, and the verticality of the anode A cannot be optimized. However, if the movement amount adjustment unit uses the above information to determine the optimum movement amount of the pressure block 15 (the movement amount shortened by 1 mm in the above example), the deformation amount of the pair of ear portions C and C is the optimum amount. Therefore, the verticality of the anode A can be improved.

  It was confirmed that the anode straightening device of the present invention is effective for straightening the ears of the anode.

First, it was confirmed whether or not the reference block thickness adjustment time could be shortened by the anode straightening device of the present invention. In the experiment, the thickness of the reference block was adjusted 8 times on the day when the equipment was not in operation, and the time required for adjusting the thickness of the reference block was changed by changing the operator.
As a result, the average time required for adjusting the thickness of the reference block was about 5 minutes, and could be reduced to 1/5 or less of the conventional block replacement time (25 to 30 minutes). With this time, even if the operation of the facility is temporarily stopped, the influence on the next process or the like can be minimized, and the thickness of the reference block can be adjusted even on the operation day of the facility.

  Further, according to the thickness measurement result of the anode ears input to the correction device, the amount of deformation was adjusted at any time to correct the anode ears, and the suspension of the anode was confirmed. Suspension here refers to a state in which a vertical plane passing through two contact points of the anode holding portion and the ear portion is set in a state where the anode ear portion is hung on a horizontal anode holding portion and suspended at the lower end height of the anode. The distance from this vertical plane to the surface of the anode was expressed. It can be determined that the shorter the distance, the better the suspension. The distance from the vertical plane to the anode surface was measured with a laser distance meter, and the distance was calculated based on this measured value.

When 30 samples were sampled from the corrected anode (1680 sheets per day) and the suspension was measured, the suspension was an average of 7 mm.
On the other hand, as a comparative example 1, when 30 samples were sampled from anodes (1680 sheets per day) in which the ears of the anode were not corrected, the suspension properties were measured, and the average suspension property was 14 mm.

  From the above results, it was confirmed that in the anode straightening device of the present invention, the thickness adjustment of the reference block can be easily and quickly performed, and the straightened anode has improved suspendability.

  The anode straightening device of the present invention is suitable for a device for straightening the ear portion of a cast anode used in electrolytic smelting of copper, lead, silver or the like.
