Description

  The present invention relates to a fine iron powder removing device, particularly in the food industry, chemical industry, ceramic industry, etc., installed in the middle of a raw material supply path for the purpose of removing fine iron powder mainly mixed in a liquid material. It is related with the fine iron powder removal apparatus used for it.

  Conventionally, as a means for removing fine iron powder mixed in raw materials in the food industry, chemical industry, ceramic industry, etc., a fine iron powder removing device that is installed and used in the middle of the raw material supply path has been proposed. (For example, see Patent Documents 1 to 3).

  As shown in FIG. 5, the fine iron powder removing device has an inlet 21 for introducing a raw material mixed with fine iron powder and an outlet 22 for discharging the raw material, and a main body 2 disposed in the raw material supply path. And a detachably mounted body 2 comprising a plurality of bottomed tube bodies 30 made of a non-magnetic material inserted into the body 2 and a partition wall 31 that fixes the open end side of the tube body 30. It consists of the member 3 and the magnetic element 4 disposed in the tube 30 of the isolation member 3 so as to be insertable / removable, and with the magnetic element 4 inserted into the tube 30, the raw material is circulated through the raw material supply path. Thus, the fine iron powder mixed in the raw material is adsorbed to the tubular body 30 to remove the fine iron powder from the raw material.

When the amount of adsorbed fine iron powder increases, the fine iron powder is stacked, and the adsorption position of the newly adsorbed fine iron powder is separated from the surface of the tubular body 30. Decreases depending on the amount of powder adsorbed.
For this reason, the cleaning operation | work which removes the fine iron powder adhering to the tubular body 30 is needed regularly.
As shown in FIG. 6A, the cleaning operation for removing the fine iron powder attached to the tubular body 30 of the fine iron powder removing device 50 is performed by removing the separating member 3 from the main body 2 and moving it to the cleaning place C. In the cleaning place C, as shown in FIG. 6B, the fine iron powder adsorbed on the surface of the tubular body 30 is washed in a state where the magnetic element 4 is detached from the tubular body 30.

By the way, when the separating member 3 removed from the main body 2 is moved to the cleaning place C, the tubular body 30 of the separating member 3 is exposed, and the separating member 3 is dropped on the floor surface or brought into contact with another object. The tubular body 30 may be deformed or damaged by bumping or dragging.
The gap between the outer peripheral surface of the magnetic element 4 and the inner peripheral surface of the tubular body 30 is configured to be as small as possible because fine iron powder needs to be adsorbed to the surface of the tubular body 30 efficiently. When the tubular body 30 is deformed, there is a problem that it is difficult or impossible to insert the magnetic element 4 into the tubular body 30.
Further, when the tube body 30 is broken, there is a problem that the liquid raw material flowing through the raw material supply path enters the tube body 30 and the magnetic element 4 is rusted.

  In view of the problems of the above-described conventional fine iron powder removing device, the present invention removes the separating member from the main body and prevents the pipe body from being deformed or damaged when moving to the cleaning place. It aims at providing a powder removal apparatus.

The tubular body protecting member is arranged in parallel to the tubular body so that a common circumscribed surface of the adjacent tubular body protecting members is positioned outside the plurality of tubular bodies.

  In this case, three rod-shaped tube protection members are arranged on the isolation member, and the plurality of tubes are positioned in a space formed by a common circumscribed surface of adjacent tube protection members. Can be.

  According to the fine iron powder removing device of the present invention, a plurality of rod-shaped tube body protection members having a length equal to or longer than the length of the tube body are provided on the separating member, and a common circumscribed surface of adjacent tube body protection members. When the separator is removed from the main body and exposed to the cleaning place with the pipes exposed, by arranging them in parallel to the pipes so that is positioned outside the plurality of pipes In addition, the tubular body is protected by the tubular body protecting member, and the tubular body can be prevented from being deformed or damaged.

  Further, three rod-shaped tube protection members are arranged on the separating member, and the plurality of tubes are positioned in a space formed by a common circumscribed surface of adjacent tube protection members. Therefore, the small number of tube protection members, such as three, can reliably protect the tube against impacts from any direction, and the cost increase due to the provision of the tube protection member is minimized. Can be suppressed.

  Hereinafter, embodiments of the fine iron powder removing device of the present invention will be described with reference to the drawings.

1 to 4 show an embodiment of the fine iron powder removing apparatus of the present invention.
This fine iron powder removing apparatus 1 has an inlet 21 for introducing raw materials mixed with fine iron powder and an outlet 22 for discharging raw materials, and a main body 2 disposed in a raw material supply path, A separating member 3 detachably mounted on a main body 2 comprising a plurality of bottomed tube bodies 30 made of a nonmagnetic material to be inserted and a partition wall 31 that fixes the open end side of the tube body; A plurality of rod-shaped tube protection members 5 having a length equal to or greater than the length of the tube 30. The common circumscribed surface 5A of the adjacent tube body protecting members 5 is arranged in parallel to the tube body 30 so as to be located outside the plurality of tube bodies 30.

  The main body 2 is formed by using the main body 2 in the middle of the raw material supply path of the food industry, chemical industry, ceramics, etc., so that an inlet 21 for introducing the flange-shaped raw material and an outlet 22 for discharging the raw material are formed. In addition, a flange-like opening 23 for inserting and fixing the separating member 3 is fixed to the upper part of the main body 2, and a flange-like opening 24 for attaching the inspection lid 25 to the lower part of the main body 2. Respectively.

The separating member 3 inserted into the main body 2 includes a plurality of tube bodies 30 made of a non-magnetic material positioned in the main body 2 when the separating member 3 is inserted and fixed in the main body 2, and Consists of a partition wall 31 to be held and a tubular body 32 that is in communication with each tubular body 30 and that is separably connected to a tubular body 31 a that extends upward from the periphery of the partition wall 31. Is done.
A handle 33 for lifting the isolation member 3 is provided at an appropriate position on the side surface of the cylindrical body 32 when the cylinder body 32 is attached or moved to a cleaning place.
And the magnetic element 4 arrange | positioned so that insertion / removal in the tube 30 is possible, the connection board 40 which fixed the edge part of each magnetic element 4, and the magnetic element 4 in the tube 30 and the cylinder 32 The rod 41 is configured to move the connecting plate 40 so as to be selectively positioned at either position, and a grip 41A provided at the tip of the rod 41.
The tip of the rod 41 is sealed with a sealing material from an opening formed in the top plate of the cylindrical body 32 and protrudes to the outside so as to provide a gripping portion 41A, and the magnetic element 4 is pulled out by pulling the gripping portion 41A upward. The tube 30 can be detached from the inside.

The tube 30 of the separating member 3 is formed by drilling the center of a round bar made of a non-magnetic material, for example, stainless steel, synthetic resin or the like, or by welding a bottom plate to the tube material. A bottomed member made of a material is used.
The tube body 30 is attached to the partition wall 31 by welding, bonding, shrink fitting or the like to the through hole formed in the partition wall 31 so that the main body 2 and the cylinder body 32 do not communicate with each other. That is, the raw material is prevented from flowing into the cylindrical body 32, and in particular, when the tubular body 30 is welded and held to the partition wall 31, the tubular body 30 is not damaged by welding. The thickness of the holding part by the partition wall 31 of the body 30 is made thicker than the thickness of the other part, for example, the thickness of the holding part is 1 mm and the thickness of the other part is 0.5 mm. It is desirable to partially cut the outer periphery of the round bar.

  The number of tube bodies 30 is not particularly limited as long as a plurality of tube bodies 30 are provided, but in this embodiment, one tube body 30 and six tube bodies 30 are provided at equal intervals around the center. I am doing so.

The tubular body protecting member 5 that protects the tubular body 30 is attached outwardly from the flange portion 34 that is attached to the flange portion 34 where the cylindrical body 31a and the cylindrical body 32 are joined to each other. It is made to arrange | position by the fixing means, such as a volt | bolt and welding, to the mounting plate 35 which protrudes toward.
As shown in FIG. 1, the tubular body protecting member 5 is attached at a height close to the open end of the tubular body 30 (height of the partition wall 31), and the length of the tubular body protecting member 5. By setting the length of the tube body 30 to be longer than the length of the tube body 30, the distal end portion of the tube body protection member 5 is positioned closer to the distal end side than the closed end of the tube body 30, and the tube body 30 is reliably protected to the closed end. To be able to.

The number of the tubular body protection members 5 is three or more in order to protect the tubular body 30 from four sides, and the common circumscribed surface 5A of the adjacent tubular body protection members 5 is located outside the plurality of tubular bodies 30. In this embodiment, as shown in FIG. 2, three rod-shaped tube protection members 5 are arranged, and adjacent tube protection members 5, A plurality of tube bodies 30 are positioned in a space 5B formed by five common circumscribed surfaces 5A.
When three tube protection members 5 are arranged, as shown in FIG. 2, they are arranged at a position where they do not interfere with the main body 2, and as shown in the figure, equidistantly around the rod 41 (form equilateral triangles). Preferably).

  Thereby, the tube body 30 can be reliably protected against impacts from any direction by the small number of the tube body protection members 5 of three, and the cost due to the provision of the tube body protection member 5. Up can be minimized.

In addition, the tube protection member 5 can increase the number of arrangement within a range in which the clamp fitting 6 that fixes the isolation member 3 to the main body 2 acts and does not interfere with the main body 2. 3 (see FIG. 3A) or 6 (see FIG. 3B).
By increasing the number of arrangements, the distance between the adjacent tube body protection members 5 can be shortened, and the tube body 30 taken out from the main body 2 and exposed can be more reliably protected.

Next, the point of the cleaning operation | work of the pipe body 30 of this fine iron powder removal apparatus 1 is demonstrated.
When the amount of adsorbed fine iron powder increases, the fine iron powder is stacked, the adsorption position of the newly adsorbed fine iron powder is separated from the surface of the tubular body 30, and the adsorption capacity is the adsorption of fine iron powder. Since the amount decreases depending on the amount, cleaning work is periodically performed after a predetermined time of operation.

  First, after stopping the distribution of raw materials, as shown in FIG. 4, the clamp fitting 6 that fixes the flange-like opening 23 at the top of the main body 2 and the isolation member 3 inserted from the opening 23 is removed. The isolation member 3 is removed from the main body 2.

Then, the separating member 3 removed from the main body 2 is moved to the cleaning place.
At this time, the tubular body 30 of the isolation member 3 is exposed, but the tubular body 30 is located in the space 5B formed by the common circumscribed surface 5A of the adjacent tubular body protecting members 5 and 5. The closed end is also located on the inner side of the end of the tube protection member 5, and while moving to the cleaning place C, the isolation member 3 is dropped on the floor surface, brought into contact with other objects, bumped or dragged. By doing so, the tubular body 30 can be reliably prevented from being deformed or damaged.
Then, in the cleaning place C, for example, the tubular body 30 of the separating member 3 is immersed in a cleaning tank, and the fine iron powder adsorbed on the surface of the tubular body 30 in a state where the magnetic element 4 is detached from the tubular body 30 is washed.

  As mentioned above, although the fine iron powder removal apparatus of this invention was demonstrated based on the Example, this invention is not limited to the structure described in the said Example, The structure suitably in the range which does not deviate from the meaning. Can be changed.

  The fine iron powder removing device of the present invention can remove the isolation member from the main body and prevent the tube from being deformed or damaged when moving to the cleaning place. It can use suitably for the use of the fine iron powder removal apparatus arrange | positioned possible.
