Description

Technical Field

[0001] The invention relates to the technical field of dust removal in coal mine operations, and in particular to high-efficiency dust removal equipment in coal mine operations. Background Art

[0002] A coal mine is an area where people mine coal resources in a coal-rich mining area. According to the different forms of mining, coal mines can be divided into underground coal mines and open-pit coal mines. Underground coal mines mine coal by digging tunnels underground. In the process of mining coal, a large amount of dust will be generated. If the dust is not handled in time, it will have an adverse effect on the health of the workers and seriously endanger the health and life safety of the workers. Therefore, it is necessary to use coal mine operation ventilation and dust removal equipment to control the air in the coal mining area.

[0003] At present, the dust removal device for underground coal mine operations is generally composed of a blower and a ventilation duct, and the blower and the ventilation duct are fixedly installed on the wall of the coal mine. The dust generated by the working surface is extracted by the blower. However, the dust removal port of this ventilation and dust removal device is fixed, and some coal mining working surfaces are far away from the dust removal port, which reduces the dust removal efficiency of the traditional ventilation and dust removal device. At the same time, the dust removal port angle of the current ventilation and dust removal device is relatively single, and it is difficult to adjust the angle of the dust removal port according to the actual situation of the coal mining working area, which makes the flexibility of the traditional ventilation and dust removal device low.

[0004] On the other hand, a patent with the search announcement number CN109236349B discloses a slag removal and dust removal equipment for coal mining. The device ensures the life safety of the practitioners and can collect and screen the coal slag within the air flow, which improves practicality and reduces production costs. However, it is difficult for the device to maintain an efficient dust removal state. After long-term use, the filter screen inside the current dust removal device is attached with a large amount of dust and gravel, which will directly affect the ventilation of the filter screen, thereby reducing the dust removal efficiency of the dust removal device. At the same time, due to the high dust content in the coal mining area, the dust removal device needs to clean the filter screen after a short period of use. The cleaning process requires disassembly, which is cumbersome and time-consuming, and the dust removal device cannot perform dust removal during the cleaning period. To this end, we provide a high-efficiency dust removal device for coal mine operations to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to make up for the deficiencies of the prior art and provide an efficient dust removal equipment for coal mine operations, including a bearing box body, the bearing box body including a cylindrical cavity and a wedge-shaped cavity, the cylindrical cavity is fixedly connected above the wedge-shaped cavity, a negative pressure fan is installed above the cylindrical cavity, both sides of the cylindrical cavity are fixedly connected with a three-way pipe, and the two ports above each of the three-way pipes are provided with an adjustment mechanism, the inner bottom wall of the wedge-shaped cavity is slidably connected with a collecting box, and the outside of the wedge-shaped cavity is installed with rollers for moving the device, so that the staff can move the device to the coal mining area conveniently. Through the setting of the collecting box, the swept dust will be collected in the collecting box, so that the staff can carry out unified treatment of the filtered dust conveniently.

[0006] The above-mentioned adjustment mechanism includes a suction pipe and an annular block fixed on the tee pipe, an expansion tube is fixed on one end of the suction pipe away from the tee pipe, a slip ring is fixed on the outer surface of the suction pipe, a plurality of limit columns in a circular array are fixed on the side of the slip ring close to the tee pipe, a plurality of limit holes matched with the limit columns are opened on the outer surface of the annular block, and the number of the limit holes is consistent with the number of the limit columns, a handle is provided on the suction pipe, which is convenient for the staff to pull and rotate the suction pipe, and the dust suction angle of the expansion tube on the suction pipe is maintained by respectively inserting the plurality of limit columns into the plurality of limit holes.

[0007] The outer surface of the slip ring 1 is rotatably connected with an annular slide rail, and four fixing rods are fixed on one side of the annular slide rail close to the annular block, and the four fixing rods are slidably connected with the annular block, and the outer surfaces of the four fixing rods are sleeved with telescopic springs 1, and the ends of the four fixing rods away from the annular slide rail are fixed with stoppers 1, and the four stoppers are respectively fixed to one end of four telescopic springs 1, and the other ends of the four telescopic springs 1 are fixed to the outer surface of the annular block. Pull the suction pipe away from the three-way pipe to separate the limit column from the limit hole, and then hold the handle on the suction pipe to rotate the suction pipe, so that the suction pipe drives the slip ring 1 and the annular slide rail to rotate, and after rotating the expansion tube to a suitable dust suction angle, release the suction pipe, so that the annular slide rail is reset by the spring tension of the four telescopic springs, so that the annular slide rail drives the slip ring 1 to approach the three-way pipe, and the limit column on the slip ring 1 will be inserted into the limit hole of the annular block to lock the expansion tube after the angle is adjusted.

[0008] A rotation mechanism is provided inside the cylindrical cavity, and the rotation mechanism includes two notched rings, both of which are fixedly connected to the inner wall of the cylindrical cavity, and an isolation plate is rotatably connected to the inner wall of the cylindrical cavity. Both of the notched rings are slidably connected to the isolation plate, and a motor 1 is fixed to the outer surface of the cylindrical cavity, and the output end of the motor 1 is fixed to the isolation plate, and filter cartridges adapted to the three-way pipe are provided on both sides of the isolation plate, and raised ring blocks adapted to the notched rings are fixed at both ends of the two filter cartridges, and elastic components for resetting the filter cartridge are provided on both sides of each of the filter cartridges.

[0009] The above-mentioned elastic component includes a fixed seat fixed on the isolation plate and a fixed block fixed on the filter cartridge, two anti-fall columns are fixed on the outer surface of the fixed seat, and a sliding rod is fixed on the end of the two anti-fall columns away from the fixed seat, and the two sliding rods are slidably connected to the fixed block, and a stopper 2 is fixed on the end of the two sliding rods away from the fixed seat, and a telescopic spring 2 is fixed between the fixed block and the fixed seat. After the isolation plate is flipped 180 degrees, the filter cartridge originally on the upper side is rotated to the lower side. At this time, the raised ring block on the filter cartridge rotates to the notch part of the notch ring, and the raised ring block is no longer squeezed by the notch ring, so that the fixed blocks on both sides of the filter cartridge move downward under the spring pressure of the telescopic spring 2, and the fixed blocks are blocked and limited by the two stoppers 2, so that the position of the lower filter cartridge corresponds to the cleaning brush.

[0010] A cleaning mechanism is provided inside the wedge-shaped cavity, and the cleaning mechanism includes a T-shaped bearing plate, a rotating rod four and a reciprocating threaded rod. A driving assembly for moving the T-shaped bearing plate is provided on the side of the T-shaped bearing plate away from the rotation mechanism. The rotating rod four is rotatably connected to the T-shaped bearing plate, and a rotating tube two is slidably connected to the outer surface of the rotating rod four, and a cleaning brush matched with the filter cartridge is fixedly connected to the outer surface of the rotating tube two. A rotating rod three is provided below the T-shaped bearing plate, and the rotating rod three is rotatably connected to the T-shaped bearing plate. A plug two is fixed to one end of the rotating rod three close to the rotation mechanism, and a top pressure assembly matched with the plug two is provided below the isolation plate.

[0011] The above-mentioned rotation mechanism also includes a rotating rod 1, the outer surface of which is rotatably connected to a support frame, and the support frame is fixed to the inner wall of the wedge-shaped cavity. The outer surface of the rotating rod 1 is fixedly connected to two cam blocks that are compatible with the raised ring blocks. The end of the rotating rod 1 close to the cleaning mechanism is fixedly connected to a plug 1 that is compatible with the plug 2. When the rotating rod 3 rotates, the rotating rod 1 is driven to rotate through the engagement of the plug 2 and the plug 1. The rotation of the rotating rod 1 will drive the two cam blocks to hit the two raised ring blocks on the lower filter cartridge respectively, squeezing the filter cartridge upward, and after the filter cartridge is squeezed, it is reset by the spring pressure of the telescopic springs on both sides, so that the filter cartridge is continuously hit by the cam block to generate vibration, and dust particles on the filter cartridge are removed by vibration.

[0012] The above-mentioned driving assembly includes motor 2 and motor 3, and motor 2 and motor 3 are both fixedly connected to the outer surface of the wedge-shaped cavity. A one-way threaded rod is fixed to the output end of motor 3, and a rotating rod 2 is fixed to the output end of motor 2. The rotating rod 2 and the one-way threaded rod close to the rotation mechanism are both rotatably connected to a limit plate. The two limit plates are both fixed to the inner wall of the wedge-shaped cavity. The outer surface of the one-way threaded rod is threadedly connected with a threaded tube 1, and the threaded tube 1 is fixed to the T-shaped load-bearing plate. The one-way threaded rod is driven to rotate by controlling motor 3. The rotation of the one-way threaded rod drives the T-shaped load-bearing plate to move through the threaded tube 1. The movement range of the T-shaped load-bearing plate is limited by the setting of the limit plate.

[0013] The outer surface of the rotating rod 2 is slidably connected with a rotating tube 1, and two slide bars 1 are fixed to the inner wall of the rotating tube 1. Both of the two slide bars 1 are slidably connected to the rotating rod 2. The rotating tube 1 is rotatably connected to the T-shaped bearing plate. The rotating tube 1 is transmission connected to the rotating rod 3 through a belt and a pulley. When the control motor 2 drives the rotating rod 2 to rotate, the rotating rod 2 drives the rotating tube 1 to rotate through the two slide bars 1. The rotation of the rotating tube 1 drives the rotating rod 3 to rotate through the belt, thereby providing power for the rotation of the plug 2.

[0014] The rotating rod three is transmission connected with the rotating rod four through a belt and a pulley, a gear one is fixed on the outer surface of the rotating rod four, a reciprocating threaded rod is arranged on one side of the rotating rod four, a threaded tube two is threadedly connected to the outer surface of the reciprocating threaded rod, the threaded tube two is rotationally connected to the T-shaped bearing plate, a gear two is fixedly connected to the outer surface of the threaded tube two, the gear two is meshed with the gear one, three sliding bars two in a circular array are fixed to the outer surface of the rotating rod four, the three sliding bars two are all slidingly connected to the rotating tube two, a slip ring two is fixedly connected to the outer surface of the rotating tube two, a drag ring is fixedly connected to the end of the reciprocating threaded rod away from the T-shaped bearing plate, and the drag ring is rotationally connected to the slip ring two.

[0015] When the rotating rod three rotates, the rotating rod four rotates through the belt. The rotation of the rotating rod four drives the threaded tube two to rotate through the meshing of gear one and gear two. Since the reciprocating threaded rod has a reciprocating thread, when the threaded tube two rotates, the reciprocating threaded rod will pull the drag ring to move back and forth, so that the drag ring pulls the slip ring two to make the cleaning brush on the rotating tube two scratch the inner wall of the filter cartridge. At the same time, when the rotating rod four rotates, the cleaning brush on the rotating tube two will be driven to rotate through the three slide bars two, so that the cleaning brush rotates in the filter cartridge and scrapes back and forth to clean the dust inside the filter cartridge. The bristles of the cleaning brush have a certain flexibility, and the operation of the cleaning brush is not affected when the filter cartridge vibrates up and down.

[0016] Compared with the existing technology, this coal mine operation high-efficiency dust removal equipment has the following beneficial effects:

[0017] 1. The present invention is provided with a rotation mechanism and a cleaning mechanism. After the filter cartridge located on the upper side of the isolation plate accumulates too much dust, the isolation plate is rotated 180 degrees by controlling motor 1, and the filter cartridge originally on the lower side is flipped into the cylindrical cavity for dust removal, while the filter cartridge originally on the upper side is flipped into the wedge-shaped cavity. Then, motor 3 is controlled to drive the T-shaped bearing plate to move, so that the slide bar 2 and the reciprocating threaded rod are inserted into the filter cartridge, and motor 2 is controlled to drive the rotating rod 2 to rotate so that the cleaning brush reciprocates and cleans the inner wall of the filter cartridge. At the same time, the filter cartridge will vibrate due to the continuous impact of the cam block, so that the dust accumulated in the filter cartridge is completely separated from the filter cartridge and falls into the collection box, so that the device can complete the cleaning of the filter cartridge without affecting the dust removal work. Moreover, through the working mode of the two filter cartridges cleaning and filtering in turn, the device can perform long-term and efficient dust removal operations in the coal mining area.

[0018] 2. The present invention is provided with a bearing box and an adjusting mechanism. Since rollers for moving the device are installed on the outside of the wedge-shaped cavity, it is convenient for workers to move the device to the coal mining area. Then, the suction pipe is pulled to drive the suction pipe to rotate, so that the expansion pipe is rotated to a suitable suction angle, and the limiting column is inserted into the limiting hole to maintain the angle of the expansion pipe so that the expansion pipe can be aligned with the mining position, making the device highly flexible. At the same time, four expansion pipes are provided, so that the device can suck in the surrounding dust from multiple directions, so that the device can efficiently vacuum the coal mining area.

The three sliding bars two 714 are all slidably connected to the rotating tube two 720. The outer surface of the rotating tube two 720 is fixedly connected to a slip ring two 721. The end of the reciprocating threaded rod 716 away from the T-shaped bearing plate 701 is fixedly connected to a drag ring 719. The drag ring 719 is rotatably connected to the slip ring two 721. When rod three 710 rotates, rotating rod four 713 is rotated through the belt. The rotation of rotating rod four 713 drives threaded tube two 717 to rotate through the meshing of gear one 715 and gear two 718. Since the reciprocating threaded rod 716 has a reciprocating thread, when threaded tube two 717 rotates, the reciprocating threaded rod 716 will pull the drag ring 719 to move back and forth, so that the drag ring 719 pulls the slip ring two 721 to make the cleaning brush 722 on the rotating tube two 720 scratch the inner wall of the filter cartridge 608. At the same time, when rotating rod four 713 rotates, it will drive the cleaning brush 722 on the rotating tube two 720 to rotate through the three slide bars two 714, so that the cleaning brush 722 rotates in the filter cartridge 608 and scrapes back and forth to clean the dust inside the filter cartridge 608. The bristles of the cleaning brush 722 have a certain flexibility, and the operation of the cleaning brush 722 is not affected when the filter cartridge 608 vibrates up and down.

[0051] Working principle: when in use, the device is moved to the coal mining area, the suction pipe 401 is pulled away from the three-way pipe 3, the limiting column 404 is separated from the limiting hole 410, and then the handle on the suction pipe 401 is held to rotate the suction pipe 401, so that the suction pipe 401 drives the slip ring 403 and the annular slide rail 405 to rotate, and after the expansion tube 402 is rotated to a suitable position, the suction pipe 401 is released, and the annular slide rail 405 is reset by the spring tension of four telescopic springs 408, so that the annular slide rail 405 drives the slip ring 403 to approach the three-way pipe 3, and the limiting column 404 on the slip ring 403 will be inserted into the limiting hole 410 of the annular block 409, locking the expansion tube 402 after the angle adjustment, and similarly adjust the suction angles of other expansion tubes 402, so that the device can inhale the surrounding dust in multiple directions.

[0052] When performing dust removal work, the cylindrical cavity 101 is isolated by the isolation plate 601, and the negative pressure fan 2 is controlled to start. The negative pressure wind of the negative pressure fan 2 will absorb the surrounding dust through the upper filter cartridge 608, the three-way pipe 3 and the suction pipe 401 in turn. The dust flows through the filter cartridge 608 and is filtered by the filter cartridge 608, thereby achieving the dust removal effect.

[0053] After long-term use, when the filter cartridge 608 located on the upper side of the isolation plate 601 accumulates too much dust, the control motor 1 602 drives the isolation plate 601 to rotate 180 degrees, and the filter cartridge 608 originally located on the lower side is flipped into the cylindrical cavity 101 for dust removal, and the filter cartridge 608 originally on the upper side is flipped into the wedge-shaped cavity 102, and then the control motor 3 703 drives the one-way threaded rod 705 to rotate, and the rotation of the one-way threaded rod 705 drives the T-shaped supporting plate 701 to move, and the movement of the T-shaped supporting plate 701 causes the slide bar 2 714 and the reciprocating threaded rod 716 to be inserted into the filter cartridge 608, and at the same time, the T-shaped supporting plate 701 will drive the plug 2 711 to engage with the plug 1 607.

[0054] The control motor 2 702 drives the rotating rod 2 704 to rotate, and the rotation of the rotating rod 2 704 drives the rotating tube 1 707 to rotate through the slide bar 1 712. The rotation of the rotating tube 1 707 drives the rotating rod 3 710 to rotate through the belt transmission, and drives the rotating rod 1 605 to rotate through the engagement of the plug 2 711 and the plug 1 607. The rotation of the rotating rod 1 605 will drive the two cam blocks 606 to hit the two raised ring blocks 609 on the filter cartridge 608 respectively, squeezing the filter cartridge 608 upward, and after being squeezed, the filter cartridge 608 is reset by the spring pressure of the telescopic springs 2 614 on both sides, so that the filter cartridge 608 is continuously hit by the cam block 606 to vibrate, and the dust particles on the filter cartridge 608 are removed by the vibration.

[0055] When the rotating rod three 710 rotates, the rotating rod four 713 is driven to rotate. The rotation of the rotating rod four 713 drives the cleaning brush 722 on the rotating tube two 720 to rotate through the three sliding bars two 714. When the rotating rod four 713 rotates, the meshing of the gear one 715 and the gear two 718 drives the threaded tube two 717 to rotate. Since the reciprocating threaded rod 716 has a reciprocating thread, when the threaded tube two 717 rotates, the reciprocating threaded rod 716 will pull the drag ring 719 to move back and forth, so that the cleaning brush 722 reciprocates to clean the inner wall of the filter cartridge 608. The dust accumulated in the filter cartridge 608 will fall into the collection box 5, so that the device can complete the cleaning work of the filter cartridge 608 without affecting the dust removal work. In addition, through the working mode of cleaning and filtering the two filter cartridges 608 in turn, the device can perform long-term and efficient dust removal operations in the coal mining area.
