Description

  The present invention relates to a cleaning tool that removes deposits adhering to an inner wall surface of a tubular body such as a pipe, a chimney, and a container and cleans the tubular body, and a cleaning device using the same. It also relates to a cyclone cleaning method.

  Brushes are often used to clean the inner wall surfaces of pipes, chimneys, containers, etc., and the pipes are cleaned by scraping off objects to be cleaned such as soot and powder attached to the pipes. Yes. When piping is long, a brush is often attached to the tip of the rod. In addition to brushes, cleaning tools for cleaning the inner surface of pipes have been developed.

  When cleaning the inner wall surface of a pipe, it is relatively easy to clean if the pipe is a straight pipe, but it is well known that it is difficult to clean if the pipe has a bent part or a step such as expansion or contraction. is there. In addition to this, it is not easy to clean a pipe having a tapered portion in which the pipe diameter gradually decreases or expands, and when the pipe length is long and the pipe diameter is large, cleaning becomes more difficult.

  FIG. 8 is a diagram illustrating an example of a conventional pipe cleaning method, and is a diagram illustrating a state in which the multi-cyclone dust collector 1 used in a pressurized fluidized bed power generation facility is being cleaned. The multi-cyclone dust collecting apparatus 1 includes a dust cutting device 2 at the bottom, and a large number of cyclones 3 are accommodated in the pressure vessel 4. The inner diameter of the pressure vessel 4 extends to several meters, and the cyclone 3 The height of a few meters. Further, since the cyclone 3 includes the dust collection chamber 5 at the lower part, a step is generated at the lower part of the cyclone 3. For this reason, it becomes difficult to clean the dust collection chamber from the upper part of the cyclone 3, and the cleaner needs to clean from below the cyclone 3. Along with this, a scaffold 6 for cleaning is required. Furthermore, since the cleaning staff cleans from the lower side of the cyclone 3, the duster is covered with dust. Thus, it is not easy to clean a large cyclone.

As a cleaning tool for easily cleaning the inner wall surface of a pipe having a bent portion, a plurality of sponge-like wipers are connected in series with a connectable body that can be flexibly connected, and these are connected by a wire. Tools have been developed (see, for example, Patent Document 1). Further, as a cyclone cleaning device having a tapered portion, a cyclone cleaning device has been developed that includes a cleaning wire attached to a center support member, and further provided with a locking tool and a rotation drive device at both ends of the center support member (for example, patents). Reference 2).

  FIG. 1 is a diagram showing a schematic configuration of a cleaning tool 10 as an embodiment of the present invention. The cleaning tool 10 is a cleaning tool for cleaning dust and the like adhering to the inside of a pipe, and a cleaning brush 50 is rotatably attached to an end portion 21 of a rod-like body 20 such as a pipe via a link mechanism 30. It has been. When cleaning the pipe, the cleaning tool 10 is inserted into the pipe, and the cleaning brush 50 is brought into contact with the inner wall of the pipe via the link mechanism 30 for use. The link mechanism 30 includes a first link arm 31 (31a, 31b, 31c (not shown), 31d (not shown)), and a second link arm 32 (32a, 32b, 32c (not shown), 32d (not shown)). , A fixed support 33 (33a, 33b, 33c, 33d (not shown)), a sliding support 34, and a string-like body 35 tied to the sliding support 34.

  A fixed support 33 that rotatably supports the first link arm 31 is fixed to one end 21 of the pipe 20, and the first link arm 31 is attached to the support shaft 36 (36 a, 36 b) on the fixed support 33. ) To be pivotable. In the present embodiment, the fixed supports 33a, 33b, 33c, 33d (not shown) are evenly arranged at positions where the cross section of the pipe 20 is divided into four, and the first link arm 31a is attached to each fixed support 33. , 31b, 31c (not shown), 31d (not shown) are connected. The fixed support 33 can be directly fixed to the pipe 20 by fixing means such as welding. However, for example, a pipe having a fixed support 33 fixed beforehand around a cylindrical body that can be fitted to the pipe 20 is used. 20 may be fixed. If the number is large as in this embodiment, the latter will be easier to manufacture.

  The first link arms 31a and 31b have one ends 37a and 37b rotatably connected to the fixed supports 33a and 33b, and the other ends 38a and 38b are connected to the second link arms 32a and 32b and the support shafts 39a and 39b. And pivotably connected. The second link arms 32a and 32b that rotatably connect the one end 40a and 40b to the first link arm 31a and 31b connect the other end 41a and 41b to the sliding support 34 via the support shafts 42a and 42b. . The slide support body 34 includes a slide sleeve 45 slidably attached to the pipe 20, and second link arm support bodies 46 a, 46 b, 46 c, 46 d (four in the figure) equally provided around the slide sleeve 45. (Omitted). The slide sleeve 45 to which the second link arm support 46 is fixed is provided with an engaging portion 47 to which the string-like body 35 can be attached. The string-like body 35 is attached to the engaging portion 47. The length of the string-like body 35 is longer than the length of the pipe 20.

  The string-like body 35 functions as a driving means for moving the connecting portion 48 between the first link arm 31 and the second link arm 32 in the axial direction of the pipe 20 by moving the sliding support 34 in the axial direction of the pipe 20. To do. Therefore, a rope, a wire, a thin stick, etc. can be utilized as a string-like body.

Cleaning brushes 50a and 50b are attached in the vicinity of the connecting portions 48a and 48b of the first link arms 31a and 31b and the second link arms 32a and 32b. The cleaning brushes 50a and 50b are detachably attached to the brush fixing bases 51a and 51b fixed to the end portions 38a and 38b of the first link arms 31a and 31b with U bolts 52a, 52b, 53a and 53b. . Therefore, even when the cleaning brushes 50a and 50b are worn, they can be easily replaced .

  The cleaning means 50 is not limited to the brushes 50a and 50b. In addition to the brush, a plate-like body having rubber elasticity, a sponge, or the like can be used. Further, since the material of the brush is not limited to a specific material, metal or resin material may be selected in consideration of the material of the tube to be cleaned.

  The pipe 20 can be used by connecting the relatively short pipe 22 and lengthening the pipe 20. In this embodiment, a cylindrical member 23 that can be fitted to the pipe is fixed to one end of the extension pipe 22 by welding, the extension pipe 22 is inserted into the pipe 24, and the pipe 24 and the cylindrical member 23 are perforated. Bolts 25 are passed through and fixed in the through holes. Since the method of extending the pipe 20 is not limited to this method, the pipe 24 and the extension pipe 22 may be connected with a new-on. In addition, flanges may be provided at both ends of the pipe 24 and the extension pipe 22 to connect them.

  The connection method may be a method other than these, but a method capable of easily extending the pipe 20 is preferable. Further, since the cleaning tool 10 rotates and rotates the pipe 20 to rotate and rotate the cleaning means 50, the connecting means of the extending means of the pipe 20 does not loosen with these operations. It is necessary. By configuring the pipe 20 to be extendable, even when the inner wall surface of a long pipe is cleaned, the pipe 22 can be connected and the length of the pipe 20 can be increased for easy cleaning. On the other hand, by shortening the pipe without connecting many pipes, it becomes easy to clean the pipe having a short length. Moreover, storage becomes easy by shortening the pipe.

  A handle 27 is provided at one end portion 26 of the pipe 20 so as to be orthogonal to the pipe 20. The handle 27 is preferably a method in which the pipe 20 can be easily attached and detached, for example, a method in which a through hole is provided in the pipe 20 and the handle 27 is inserted into the through hole. As a result, the pipe 20 described above can be easily extended. By attaching the handle 27, the pipe 20 can be easily rotated and rotated, and cleaning can be easily performed.

  Further, a locking means 28 capable of lifting the pipe 20 is provided at the tip of the end portion 26 to which the handle 27 of the pipe 20 is fixed. The locking means 28 is used when lifting the pipe 20 with a hoist (not shown) or the like, and corresponds to, for example, an eyebolt 28. Since the present cleaning tool 10 has the locking means 28 at the tip 26 of the pipe 20, it becomes possible to lift the cleaning tool 10 using a hoist or the like, and the cleaner need not support the cleaning tool 10, Easy pipe cleaning. The pipe 20 has a function of supporting the link mechanism 30 and the like and sending the cleaning means 50 to a predetermined place. Therefore, if it has these functions, it is also possible to use rod-shaped bodies, such as a solid material and a square, without being limited to a pipe.

  Next, a method of using the cleaning tool 10 will be described taking an example of cleaning the inner wall surface of a vertical pipe. With the fixed support 33 downward and the handle 27 upward, the cleaning means 50 is closed and inserted into the pipe. The state where the cleaning means 50 is closed means a state where the cleaning means 50, that is, the cleaning brushes 50 a and 50 b are close to the pipe 20. FIG. 2 is a view showing a state where the cleaning brushes 50a and 50b in FIG. 1 are closed. The cleaning brushes 50a and 50b can be closed in the following manner.

  When the string-like body 35 attached to the slide sleeve 45 is pulled up, the slide sleeve 45 is pulled up while sliding on the wall surface of the pipe 20. Since the slide sleeve 45 is connected to the second link arm 32 via the second link arm support body 46, the second link arm 32 is also lifted when the slide sleeve 45 is pulled up. The other end 40 of the second link arm 32 is connected to one end 38 of the first link arm 31, and the other end 37 of the first link arm 31 is stopped from moving in the axial direction of the pipe 20 by the fixed support 33. Therefore, the connecting portion 48 of the first link arm 31 and the second link arm 32 approaches the pipe 20 by pulling up the slide sleeve 45 and moves away from the pipe 20 by lowering the slide sleeve 45.

  That is, by moving the second link arm 32 in the axial direction of the pipe 20, the connecting portion 48 between the first link arm 31 and the second link arm 32 rotates in a plane including the axis of the pipe 20. Accordingly, the cleaning brush 50 attached to the one end 38 of the first link arm 31 in the vicinity of the connecting portion 48 of the first link arm 31 and the second link arm 32 has the axis of the pipe 20 starting from the fixed support 33. Rotate in a plane containing FIG. 1 is a diagram illustrating a state in which the cleaning brushes 50a and 50b are opened to the maximum.

  After the slide sleeve 45 is pulled up and inserted into the pipe to be cleaned with the cleaning means 50 closed, the string-like body 35 is loosened and the slide sleeve 45 is lowered until the cleaning means 50 comes into contact with the inner wall surface of the pipe. . The slide sleeve 45 is slidably attached to the pipe 20 and connects the second link arm 32. Therefore, when the string-like body 35 is loosened, the slide sleeve 45 is lowered by its own weight. FIG. 3 is a diagram illustrating a state where the cleaning brushes 50a and 50b of the cleaning tool 10 of FIG. 1 are in contact with the inclined portion 70 of the pipe. When the cleaning brushes 50a and 50b contact the inner wall surface 71 of the pipe, the string-like body 35 is maintained in that state, and the opening and closing angles of the cleaning brushes 50a and 50b are fixed.

  In this state, when the handle 27 provided at the upper end 26 of the pipe 20 is rotated and rotated, the cleaning brushes 50a and 50b move in the circumferential direction of the pipe. Thereby, the inner wall surface 71 of piping can be easily cleaned. In particular, the cleaning tool shown in the present embodiment has four cleaning brushes 50a, 50b, 50c (not shown) and 50d (not shown) in the circumferential direction of the pipe 20, so that the rotation range of the pipe 20 is increased. The inner wall surface of the pipe can be easily cleaned without increasing the size.

  After the cleaning is completed, the slide sleeve 45 is pulled up again, and the cleaning tool 10 is pulled up with the cleaning brushes 50a and 50b closed. As a result, the cleaning brushes 50a and 50b are not pulled up in contact with the inner wall surface of the pipe, and the lifting operation can be easily performed.

  In the embodiment shown in FIGS. 1 to 3, the cleaning means 50 is attached to the rod-like body 20 as a turning means for turning the cleaning means 50 around the fixed support 33 in a plane including the axis of the rod-like body 20. Although an example using the link mechanism 30 that moves along the axial direction of the rod-shaped body 20 is shown, the rotating means that rotates the cleaning means 50 around the fixed support 33 in the plane including the axis of It is not limited to.

  FIG. 4 is a diagram showing a schematic configuration of a cleaning tool 80 as a second embodiment of the present invention. Portions corresponding to the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the present embodiment, unlike the first embodiment, the second link arm and the sliding support are not provided. In the first embodiment, the string-like body 35 fixed to the slide sleeve 45 is directly fixed to the end portions 38a and 38b of the first link arms 31a and 31b. Also in the second embodiment, the first link arms 31a and 31b rotate within the plane including the axis of the pipe 20 with the fixed support bodies 33a and 33b as starting points by moving the string-like bodies 35a and 35b. Accordingly, the cleaning brushes 50a and 50b fixed to the end portions 38a and 38b of the first link arms 31a and 31b can be rotated in a plane including the axis of the pipe 20, and the cleaning brush 50a and 50b can be set to an arbitrary opening / closing angle. Unlike the first embodiment, since the string-like bodies 35a and 35b are attached to the first link arms 31a and 31b, the opening and closing angles of the cleaning brushes 50a and 50b may be set separately. Is possible.

  FIG. 5 is a diagram showing a schematic configuration of a cleaning tool 100 as a third embodiment of the present invention. Portions corresponding to the first embodiment are denoted by the same reference numerals and description thereof is omitted. The cleaning tool 100 shown in the third embodiment is different from the first and second embodiments in that the link mechanisms 30 and 130 and the cleaning means 50 and 150 are provided in two stages in the axial direction of the pipe 20. The upper and lower two-stage link mechanisms 30 and 130 are the same as the link mechanisms shown in the first embodiment. Since the upper and lower two-stage link mechanisms 30 and 130 can be moved independently, the opening and closing angles of the cleaning brushes 50 and 150 can be changed vertically. Therefore, even if it is piping which has a level | step difference, it becomes possible to clean the piping before and behind a level | step difference simultaneously, and can clean efficiently. The cleaning means 50 shown in the first, second and third embodiments also rotates in the opposite direction to the sliding support 34 by loosening the string 35. Since the cleaning means 50 can be rotated in the direction opposite to the sliding support 34, the cleaning becomes easier and the cleaning range is expanded.

  In the first to third embodiments, the opening and closing angles of the cleaning brushes 50 and 150 of the cleaning tool are determined by pulling or loosening the string-like body. When the cleaning tools 10, 80, 100 are used in the vertical direction, the string-like body 35 is pulled by its own weight such as a link arm. Thereby, even if a rope, a wire, etc. are used as a string-like object, if the position of the string-like object 35 is fixed, the opening / closing angle of the cleaning brush 50 is also kept substantially constant. However, when cleaning horizontal pipes, if ropes, wires, etc. are used as the string-like body, the angle of the cleaning brushes 50, 150 varies even if the position of the string-like body 35 is fixed. It's easy to do. If a thin rod-like body that is not deformed is used as the string-like body 35, the cleaning brushes 50, 150 are used with the opening and closing angles maintained substantially constant even when the cleaning tools 10, 80, 100 are used for horizontal piping. can do.

When there is not enough space at the top of the cyclone 3 as in this cleaning, a short pipe is added and the pipe is extended and used. Thereby, even if there is little upper space and the length of piping etc. to be cleaned is long, it can be easily cleaned.

After the pipe 20 is inserted until the tip of the cleaning brush 50 passes through the upper wall surface 7 of the dust collection chamber 5, the string-like body 35 pulling up the slide sleeve 45 is loosened, and the slide sleeve 45 is lowered. As a result, the cleaning brush 50 is opened through the link mechanism 30. The string-like body 35 and the pipe 20 are pulled together, and the tip of the cleaning brush 50 is brought into contact with the upper wall surface 7 of the dust collection chamber 5. By rotating the pipe 20 in this state, the upper wall surface 7 of the dust collection chamber 5 can be cleaned. After cleaning is completed, the pipe 20 and the string-like body 35 are lowered, the string-like body 35 is pulled up, the cleaning brush 50 is closed, and the pipe 20 is pulled up. At this time, if the pipe 20 is extended, the extension pipe is sequentially removed.

  In the cyclone cleaning method shown in FIG. 6, the string-like body 35 for driving the slide sleeve 45 is held by the pulleys 9a and 9b and a hoist (not shown), so that cleaning is easy. If the cleaning tool 10 itself is also lifted by a chain block or the like using the locking means 28 provided at the tip of the pipe 20, cleaning becomes easier. As described above, even a large cyclone can be easily cleaned by a cleaner without getting dirty.
