Description

  The present invention relates to a removing machine that removes, from the conveyor belt, deposits attached to the surface of a conveyor belt that conveys a granular or powdery object to be conveyed.

  For example, in a blast furnace, a raw material such as iron ore or coke is introduced into a hopper by a belt conveyor, but a part of the raw material adheres to the surface of the conveyor belt mounted on the belt conveyor. It is important that the operation of removing the deposits from the surface of the conveyor belt is performed as much as possible to prevent wrinkles from forming on the surface of the conveyor belt. Therefore, the present applicant has developed the following removal machine (for example, refer to Patent Document 1).

  FIG. 7 is a side sectional view of a conventional removing machine developed by the present applicant. A synthetic rubber having a required hardness is formed into a belt plate having a length corresponding to the width of the conveyor belt, and is made to come into contact with the conveyor belt on one side edge of the front side of the substrate 52 to remove the deposits. A plurality of blades 53 (53, 53,...) Are detachably arranged in parallel. On the other hand, the cylindrical shaft 60 that supports the substrate 52 is positioned at an appropriate position in the longitudinal direction of the conveyance belt in the return path, with a required distance from the surface of the conveyance belt, and the central axis of the shaft is directed in the width direction of the conveyance belt. Both ends of the shaft 60 are rotatably supported by bearing members.

  At an appropriate position on the peripheral surface of the shaft 60, a rectangular plate-like support plate 70 having a length substantially the same as the length of the substrate 52 lies, and a base end portion of the support plate 70 is supported by the support plate 70. It is welded so that the required inclination angle is obtained. A reinforcing member 71 that reinforces the support plate 70 is provided between the back surface of the support plate 70 and the peripheral surface of the shaft 60.

  On the other hand, a joint member 80 for attaching the substrate 52 to the support plate 70 is disposed on the other side edge portion of the back surface side of the substrate 52 described above, and a thin side member is provided on the other side edge portion of the front side of the substrate 53. A band-shaped fixing plate 56 is arranged. Then, nuts 86 (86, 86,...) Are screwed onto a plurality of bolts 85 (85, 85,...) Penetrating the fixing plate 56, the substrate 52, and the joint member 80, respectively. The substrate 52 is sandwiched and fixed therebetween. The joint member 80 is formed by inserting a spacer 82 between two plate members 81, 81 to provide an insertion portion 83. The distal end portion of the support plate 70 described above is inserted into the insertion portion 83, and both plate members 81 are inserted. , 81 and a fixing bolt 87 (87, 87,...) Passing through the support plate 70 are screwed onto nuts 88 (88, 88,...), And the joint member 80 is detachably fixed to the support plate 70. is there. Then, the shaft 60 is rotated so that the tips of the blades 53 (53, 53,...) Arranged side by side on the substrate 52 are brought into contact with the surface of the conveyor belt, and the blades 53 (53, 53,. By energizing the force that presses against the surface of the conveyor belt, deposits adhered to the surface of the conveyor belt are scraped off from the conveyor belt.

  In such a removing machine, since the substrate 52 has an elastic force, it is possible to prevent wrinkles on the surface of the conveyor belt as much as possible, and in addition, one blade 53 (53, 53,...) Is provided. Since they are arranged side by side on the substrate 52, even if the conveyor belt meanders, the adjacent blades 53 (53, 53,...) Are prevented from overlapping each other, and the blades 53 (53, 53,. ) Is avoided, and the blades are prevented from being damaged.

  However, such a conventional removal machine has the following problems. That is, since the mounting structure of the substrate 52 is a relatively complicated structure including the support plate 70, the reinforcing member 71, and the joint member 80 as described above, the manufacturing cost of the removal machine is relatively high, and there is a demand for a reduction in equipment cost. I cannot answer the demands of those who are satisfied. On the other hand, as the length of the belt conveyor increases, the weight of the conveyor belt increases and the load applied from the conveyor belt to the removal machine also increases. To counter this load, the support plate 70, reinforcement The member 71, the joint member 80, etc. must all be made of a high-strength material, and the weight of the joint member 80 increases in addition to the increase in material cost. The work of removing the joint member 80 from the support plate 70 and the work of attaching the substrate 52 and the joint member 80 to the support plate 70 require a great deal of labor.

  The present invention has been made in view of such circumstances, and even when a large load is applied, the material cost and the manufacturing cost can be reduced, and the replacement work can be easily performed. Provide a removal machine that can

(Embodiment 1)

  FIG. 1 is a perspective view showing an example of a removing machine according to the present invention, and shows a case where the removing machine is disposed in the vicinity of a pulley of a belt conveyor. 2 is an exploded perspective view of the removing machine shown in FIG. 1, and FIG. 3 is a side sectional view showing a main part of the removing machine shown in FIG.

  As shown in FIG. 1 to FIG. 3, the removing machine has a substrate 2 formed by molding an elastic material having a required hardness into a strip shape having a thickness of about 30 mm and a height of about 90 mm, and the substrate 2. And a support base 20 for supporting the support base 20. The length of the substrate 2 is determined according to the width dimension of the conveyor belt of the belt conveyor on which the removing machine is disposed. Then, on one side edge of the front surface of the substrate 2, a plurality of (in the case shown in FIGS. 1 and 2, two) L-shaped blades 3 and 3 respectively brought into contact with the surface of the transport belt are arranged in a row. The blades 3 and 3 are detachably juxtaposed in a state where the ceiling portion is substantially flush with one side surface of the substrate 2.

  The substrate 2 described above is made of synthetic rubber such as urethane rubber and has a hardness of 70 to 120, preferably about 90. Here, when a synthetic rubber having a hardness of less than 70 is used, the force for bringing the blades 3 and 3 into contact with the conveying belt is weak, and the ability to remove the adhering matter adhering to the surface of the conveying belt is lowered. On the other hand, when a synthetic rubber having a hardness exceeding 120 is used, there is a possibility that the blades 3 and 3 are excessively brought into contact with the conveyor belt and the surface of the conveyor belt is scratched.

  A plurality of pairs (two pairs in FIG. 2) of mounting holes 2a, 2a, 2a, 2a for mounting the blades 3, 3 are provided in the longitudinal direction of the substrate 2 in the vicinity of one side edge of the substrate 2. It is opened so as to penetrate the front and back surfaces of the substrate 2 at intervals.

  The blade 3 described above is formed by fixing a blade portion 3b formed by forming an alloy having a required hardness into a flat plate shape on one side surface of a channel-shaped substrate 3a, and the tip of the blade portion 3b is on one side of the substrate 3a. A little protruding from the edge. Legs 3c and 3c are erected on the other side of the base material 3a, and threads are threaded on the peripheral surfaces of both legs 3c and 3c.

  Then, both leg portions 3c, 3c of the blade 3 are passed through the mounting holes 2a, 2a forming a pair of the substrate 2, and two leg portions 3c, 3c projecting from the both mounting holes 2a, 2a are connected to the strip-shaped metal plate. The blade 3 can be attached to and detached from the substrate 2 by fitting the washer plate 4 formed with holes and fitting the nuts 5 and 5 to the leg portions 3c and 3c protruding from the holes of the washer plate 4. It is installed.

  In the present embodiment, the L-shaped blade 3 is attached to the substrate 2 so as to be disposed in the vicinity of the pulley of the belt conveyor. However, the present invention is not limited to this and is disposed in the return path of the belt conveyor. A blade is used in which the blade 3b is fixed to a front side edge of a rectangular base material with its tip slightly protruding from the base material. As before, a pair of leg portions are erected on the back surface of the blade. When both leg portions are passed through the mounting holes 2a and 2a forming a pair of the substrate 2, the blade portion of the blade is attached to the substrate 2. It protrudes from the side edge.

  The above-described support base 20 is configured by rotatably supporting both end portions of a shaft (rod-like member) 10 using, for example, a metal round pipe by, for example, a bearing portion 21 and a block-like bearing portion 31 described later. It is. A pedestal portion 22 having a short inverted channel shape is arranged on the bearing portion 21 in parallel with each other at an appropriate distance. An annular receiving member 23 is provided at a substantially central position in the longitudinal direction of the ceiling surface of the pedestal portion 22. However, the center axis of both annular receiving members 23 is fixed so as to coincide with each other in a direction perpendicular to the longitudinal direction of the pedestal portion 22 at a distance from the upper surface of the pedestal portion 22.

  In addition, it cannot be overemphasized that it replaces with the block-shaped bearing part 31 and the bearing part 21 may be arrange | positioned.

  A long hole extending in the circumferential direction is formed in the outer peripheral surface of the annular receiving member 23 and at one end side portion of the pedestal portion 22, and is erected on the peripheral surface near one end of the shaft 10 from the long hole. A rod-shaped handle 24 is projected. Further, screw holes are formed in the outer peripheral surface of the annular receiving member 23 on the other end side portion of the pedestal portion 22 and the portion facing the pedestal portion 22. Bolts 25 and 26 are screwed into the holes, respectively, and the ends of both bolts 25 and 26 can be projected into the annular receiving member 23.

  Both end portions of the shaft 10 are loosely fitted in both annular receiving members 23, and the shaft 10 is rotated by pressing the ends of both bolts 25, 26 against the circumferential surface of the shaft 10. Is to be prohibited.

  On the other hand, a stopper bolt 27 is provided in the vicinity of one end of the pedestal portion 22 so as to penetrate the ceiling surface of the pedestal portion 22 from the lower surface side to the upper surface side. The shaft 10 is adjusted to a required rotation angle by projecting only a required dimension from the ceiling surface and abutting against the middle portion of the handle portion 24 described above.

  Two supporting walls (wall portions) 11 are provided at appropriate positions on the outer peripheral surface of the shaft 10 and are formed by standing up metal strips having a height of about 30 mm to 50 mm and a length longer than the length of the substrate 2. , 11 are arranged in parallel to each other across a dimension obtained by adding a clearance of about 5 mm to the thickness dimension of the substrate 2, for example, a dimension of about 35 mm. That is, the height dimension of the support walls 11 is lower than the height dimension of the substrate 2 described above. Then, both ends of both support walls 11 and 11 are connected by metal connection portions 12 and 12 to reinforce the structural strength of the support walls 11 and 11, and both the support walls 11 and 11 and both the connection portions 12. , 12 is a board fitting portion 15 into which the board 2 is fitted.

  In the present embodiment, the entire regions in the height direction of both ends of the support walls 11 and 11 are connected by the metal connecting portions 12 and 12. However, the present invention is not limited to this, and the connecting portion 12 is not limited thereto. , 12 may be made lower than the height dimension of the support walls 11, 11. Thereby, weight reduction of the support stand 20 can be achieved.

  The other side edge portion of the substrate 2 described above is fitted into the substrate fitting portion 15, whereby the substrate 2 is fixed to the shaft 10 in a posture orthogonal to the tangential direction of the substrate fitting portion 15. Is done. As described above, a plurality of blades 3 and 3 are attached to one side edge of the substrate 2, and after loosening both bolts 25 and 26 provided on the annular receiving member 23, the stopper bolt 27 of the base portion 22 is fixed. By adjusting the protrusion height, the rotation angle of the shaft 10 can be adjusted, and the tilting posture of the substrate 2 fixed to the shaft 10 can be adjusted.

  In this embodiment, the case where the round pipe-shaped shaft 10 is used is shown. However, the present invention is not limited to this. For example, the portion excluding both ends of the shaft 10 is formed in a square pipe shape. It goes without saying.

  FIG. 4 is a side view showing how the above-described removing machine is used. In the figure, P is a pulley disposed at a position where the belt conveyor moves from the forward path to the backward path. In the figure, parts corresponding to those shown in FIGS. 1 to 3 are denoted by the same reference numerals and description thereof is omitted.

  The pulley P is rotatably supported by a support shaft arranged in a direction intersecting the vertical direction. An annular belt-like conveying belt V is wound around the pulley P, and the conveying belt V is rotated by the pulley P from above to below as indicated by arrows. At the position below the support shaft of the pulley P, the remover 1 is arranged so that the substrate 2 of the remover 1 faces the width direction of the transport belt V wound around the pulley P. As described above, by adjusting the tilting posture of the substrate 2, each blade 3 (3) attached to the substrate 2 is brought into contact with the surface of the conveyor belt V with an appropriate load.

  In such a remover 1, since the substrate 2 has a required elastic force, it is possible to prevent wrinkles on the surface of the conveyor belt 2 by the blade 3 (3) attached to the substrate 2, and Since each blade 3 (3) is attached to a single substrate 2, even if the meandering of the conveyor belt V occurs, the substrate 2 follows the meandering and the adjacent blades 3 (3) Stacking is avoided and damage between the blades 3 (3) is prevented. On the other hand, since a downward load is applied from the conveyor belt V to the substrate 2 of the remover 1, the substrate 2 is prevented from being pulled out from the substrate fitting portion 15 of the remover 1.

  By the way, the replacement work of the substrate 2 is performed as follows. That is, since the board 2 is merely fitted to the board fitting portion 15 of the removing machine 1 without relying on bolting or the like as described above, the tilting posture of the board 2 is adjusted so as to be separated from the transport belt V. After that, the board 2 is extracted from the board fitting portion 15, and a new board is inserted and fitted into the board fitting portion 15. Then, the substrate 2 is returned to the original tilting posture.

  In this way, the replacement work of the substrate 2 is very easy, and since only the blade 3 (3) and the washer plate 4 (4) are attached to the substrate 2, it is relatively lightweight, so that the work of a small number of people is possible. In addition to being able to perform replacement work in a short time and reducing maintenance costs, it is possible to shorten the time for stopping the conveyor belt V as a production line for replacement of the substrate 2. It is possible to suppress as much as possible a decrease in the production amount related to the production line.

  Further, since the substrate 2 can be easily attached and detached in a short time, the blade 2 (3) can be replaced by removing the substrate 2 from the removing machine 1, and the blade 3 (3) can be replaced. Work can be done safely and easily.

  On the other hand, since the removal machine 1 has a relatively simple structure, the material cost and the manufacturing cost are low even when a large load is applied. Furthermore, the installation work of the remover 1 can be performed in a state where the substrate 2 is separated, and thus the installation work is easy.

In the present embodiment, the shaft 10 is rotatably supported by the support bases 21 and 31, but the present invention is not limited to this. For example, a distance is provided on the installation floor surface. The shaft 10 may be installed between two support bars that are erected. In this case, by making the shaft 10 movable up and down, the replacement work of the substrate 2 can be easily performed.
(Embodiment 2)

  FIG. 5 is an exploded perspective view showing a main configuration of the removing machine according to the second embodiment, in which the structure of the shaft is varied. In the figure, parts corresponding to those shown in FIG.

  As shown in FIG. 5, the shaft 10 is made of a solid metal bar (a round bar in the case shown in FIG. 5), and at an appropriate position on the outer peripheral surface of the shaft 10a, A groove-like substrate fitting portion 15a for internally fitting the other side portion of the substrate 2 is provided in the longitudinal direction of the shaft 10a. That is, the width dimension of the board fitting portion 15a is a dimension obtained by adding a clearance of about 5 mm to the thickness dimension of the board 2, for example, about 35 mm, and the length dimension of the board fitting portion 15a is the length of the board 2. It is a dimension obtained by adding a clearance of about 10 mm to the size. Moreover, the depth dimension of the board | substrate fitting part 15a is about 30 mm-50 mm.

As a result, since the replacement work of the substrate 2 can be easily performed as before, even a small number of workers can perform the replacement work in a short time, and the maintenance cost can be reduced. Since the time for stopping the production line for the replacement of 2 can be shortened, it is possible to suppress the decrease in the production amount related to the production line as much as possible. In addition, the blades 3 and 3 can be replaced by removing the substrate 2 from the removing machine, and the replacement work of the blades 3 and 3 can be performed safely and easily. On the other hand, since the shaft 10a has a relatively simple structure, the manufacturing cost is low even when an excessive load is applied. Further, the installation work of the remover can be performed in a state where the substrate 2 is separated, so that the installation work is easy.
(Embodiment 3)

  FIG. 6 is a perspective view showing a removing machine according to Embodiment 3, which mainly removes liquid deposits. In the figure, parts corresponding to those shown in FIG.

  As shown in FIG. 6, the removal machine according to the present embodiment is shown in FIG. 1 except that the blades 3, 3 and mounting holes 2a, 2a,... Of the removal machine shown in FIG. The configuration is substantially the same as the configuration of the remover. In such a remover, the remover is disposed at an appropriate position in the longitudinal direction of the return path of the conveyor belt or at a position opposite to the pulley that shifts from the forward path to the return path, and the tilting posture of the substrate 2 is adjusted as described above. By doing so, the front end portion of the substrate 2 is brought into contact with the surface of the transport belt with an appropriate load.

  Thereby, liquid deposits adhering to the surface of the conveyor belt can be efficiently removed without causing wrinkles on the surface of the conveyor belt. In addition, since the replacement work of the substrate 2 can be easily performed as before, even a small number of workers can perform the replacement work in a short time, and the maintenance cost can be reduced. Since it is possible to shorten the time for stopping the production line for replacement, it is possible to suppress as much as possible the reduction in the production amount related to the production line. Moreover, since the shaft 10a has a relatively simple structure, the manufacturing cost is low. Further, the installation work of the remover can be performed in a state where the substrate 2 is separated, so that the installation work is easy.

  Needless to say, the substrate 2 may have various shapes according to the conveyance belt.
