Description

Technical Field

[0001] This utility model relates to the field of mine dust removal technology, specifically a dust removal device for a fully mechanized tunneling face in a mine. Background Technology

[0002] In the longwall tunneling face of a mine, the tunneling machine generates a large amount of dust during operation. This dust not only seriously affects the vision of the workers and reduces work efficiency, but also poses a great threat to their health. Long-term inhalation of dust can easily lead to occupational diseases such as pneumoconiosis. In addition, high concentrations of dust may also cause safety accidents such as explosions, posing a huge safety hazard to mine production. In order to improve this situation, it is particularly important to develop a dust removal device for longwall tunneling faces in mines.

[0003] Referring to the CN221779490U specification, a dust removal device for underground mine tunneling faces describes a device that uses a trolley to move the equipment. A first electric cylinder extends and retracts to adjust the height of the cleaning box, enabling cleaning of dust at different heights. A second electric cylinder extends and retracts to rotate the mounting strip, adjusting it to be flush with the movable plate. A motor drives a lead screw, causing the movable plate to move the cleaning brush, brushing off dust from the filter plate surface. This achieves mechanized cleaning of the filter plate and dust collection. The entire process is convenient and requires no downtime, further improving the efficiency of dust removal at the tunneling face. However, while this device can be widely applied, it is generally not suitable for purifying dusty air generated at fully mechanized mine tunneling faces using multiple methods. This means that the device's dust removal efficiency at fully mechanized mine tunneling faces often falls short of expectations, frequently causing problems for users. Utility Model Content

[0004] The purpose of this utility model is to provide a dust removal device for mine tunneling faces, in order to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to purify the dusty air generated in the mine tunneling face in multiple ways, so that the dust removal efficiency of the device for the mine tunneling face is still difficult to achieve the expected results.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust removal device for a fully mechanized tunneling face in a mine, comprising a base, a base plate fixedly installed on the top of the base, a first dust removal tank provided on one side of the top of the base plate, and a second dust removal tank provided on the other side of the top of the base plate, an air outlet provided at the center of the top of the second dust removal tank, the bottom end of the air outlet extending into the interior of the second dust removal tank, water filling the bottom of the interior of the second dust removal tank, a large-aperture filter screen installed at the lower end of the interior of the first dust removal tank, a small-aperture filter screen installed inside the first dust removal tank above the large-aperture filter screen, an activated carbon filter screen installed inside the first dust removal tank above the small-aperture filter screen, an air inlet provided on the lower outer wall of the side of the first dust removal tank away from the second dust removal tank, one end of the air inlet extending into the interior of the first dust removal tank, and a control panel installed on the top of the base on one side of the base plate.

[0006] Preferably, an exhaust fan is provided at the top of the base between the first dust collection tank and the second dust collection tank. A first motor is installed at the top of the base on one side of the outer wall of the exhaust fan. The input end of the first motor is electrically connected to the output end of the microcontroller inside the control panel. The exhaust fan is driven to run by the first motor.

[0007] Preferably, one end of the exhaust fan is equipped with an exhaust pipe, the end of which is away from the exhaust fan is connected to the outer wall of the first dust collection tank, and the other end of the exhaust fan is equipped with an air supply pipe, the end of which extends away from the exhaust fan into the interior of the water source. The exhaust pipe and the air supply pipe are configured so that the exhaust fan can draw air from the inside of the first dust collection tank and transport it to the second dust collection tank.

[0008] Preferably, a base frame is fixedly installed at the bottom of the base, and both sides of the base frame are provided with walking tracks. The walking tracks are used to transport the entire dust removal device by track.

[0009] Preferably, a plurality of pulleys are rotatably mounted on the outer wall of the underframe on the inner side of the track. The outer wall of the pulleys meshes with the inner wall of the track. The arrangement of the plurality of pulleys is to drive the track to operate.

[0010] Preferably, a component rack is provided on the inner wall of both sides of the base frame, and a second motor is installed on the outer wall of the component rack. The input end of the second motor is electrically connected to the output end of the microcontroller inside the control panel. One end of the second motor passes through the component rack and is connected to the inner wall of a pulley. The second motor is configured to drive a pulley connected to it to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the dust removal device for the mine tunneling face not only ensures the dust removal efficiency of the mine tunneling face when the dust removal device is used, but also improves the convenience of the dust removal device during transportation, and reduces the phenomenon of blockage of the exhaust fan when the dust removal device is used.

[0012] The first dust collector is equipped with a large-pore filter, a small-pore filter, and an activated carbon filter installed sequentially from bottom to top inside. When dusty air from the mine's tunneling face flows into the lower part of the first dust collector through the air inlet, the dusty air is filtered in multiple stages by the large-pore filter, the small-pore filter, and the activated carbon filter. Then, the second dust collector is filled with water. When the air filtered in the first dust collector flows into the water in the second dust collector, the particulate matter in this part of the air will dissolve in the water, thus performing secondary filtration and purification of the air. This ensures the dust removal efficiency of the dust removal device for the mine's tunneling face.

[0013] By starting the second motor to drive a pulley to rotate slowly, the pulley, in conjunction with several pulleys on the outer wall of the base frame, drives the tracked dust removal device to move and transport the entire tracked dust removal device at the mine's fully mechanized tunneling face, thereby improving the convenience of transporting the dust removal device.

[0014] By placing the exhaust fan at the top of the base between the first and second dust collection tanks, and with the exhaust pipe and air supply pipe located between the first and second dust collection tanks, when air flows from the inside of the first dust collection tank into the exhaust pipe, exhaust fan, and air supply pipe, the air is filtered in stages by the large-pore filter, small-pore filter, and activated carbon filter inside the first dust collection tank. This reduces the flow of large particles into the exhaust fan and other related components, thereby reducing the phenomenon of the exhaust fan becoming clogged when the dust collection device is in use.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a dust removal device for a fully mechanized tunneling face in a mine, including a base 1, a base frame 2 fixedly installed at the bottom end of the base 1, and walking tracks 3 provided on both sides of the base frame 2;

[0022] In use, the dust removal device is transported and moved by the track 3.

[0023] Several pulleys 4 are rotatably mounted on the outer wall of the base frame 2 inside the track 3, and the outer wall of the pulleys 4 meshes with the inner wall of the track 3.

[0024] In use, the walking track 3 is driven to operate by setting up several pulleys 4;

[0025] The inner walls on both sides of the base frame 2 are provided with a component rack 19. A second motor 20 is installed on the outer wall of the component rack 19. The input end of the second motor 20 is electrically connected to the output end of the microcontroller inside the control panel 5. One end of the second motor 20 passes through the component rack 19 and is connected to the inner wall of a pulley 4.

[0026] In use, the second motor 20 is configured to drive a pulley 4 connected to it to rotate;

[0027] A base plate 6 is fixedly installed on the top of the base 1. A first dust removal tank 9 is provided on one side of the top of the base plate 6, and a second dust removal tank 10 is provided on the other side of the top of the base plate 6. An exhaust fan 8 is provided on the top of the base 1 between the first dust removal tank 9 and the second dust removal tank 10. A first motor 7 is installed on the top of the base 1 on one side of the outer wall of the exhaust fan 8. The input end of the first motor 7 is electrically connected to the output end of the microcontroller inside the control panel 5.

[0028] In use, the first motor 7 is configured to drive the exhaust fan 8 to operate;

[0029] One end of the exhaust fan 8 is equipped with an exhaust pipe 11. The end of the exhaust pipe 11 away from the exhaust fan 8 is connected to the outer wall of the first dust collector 9. The other end of the exhaust fan 8 is equipped with an air supply pipe 13. The end of the air supply pipe 13 away from the exhaust fan 8 extends into the interior of the water source 14.

[0030] In use, the exhaust pipe 11 and the air supply pipe 13 are set so that the exhaust fan 8 can draw the air inside the first dust collector 9 and deliver it to the second dust collector 10.

[0031] An air outlet 12 is provided at the center of the top of the second dust collector 10. The bottom end of the air outlet 12 extends into the interior of the second dust collector 10. The bottom of the interior of the second dust collector 10 is filled with water 14. A large-pore filter 16 is installed at the lower end of the interior of the first dust collector 9. A small-pore filter 17 is installed inside the first dust collector 9 above the large-pore filter 16. An activated carbon filter 18 is installed inside the first dust collector 9 above the small-pore filter 17. An air inlet 15 is provided on the lower outer wall of the first dust collector 9 away from the second dust collector 10. One end of the air inlet 15 extends into the interior of the first dust collector 9. A control panel 5 is installed at the top of the base 1 on one side of the substrate 6.

[0032] In this embodiment, the second motor 20 is first started to drive a pulley 4 to rotate slowly. This pulley 4, in conjunction with several pulleys 4 on the outer wall of the base frame 2, drives the tracked dust removal device to operate. The tracked dust removal device is then positioned on the uneven surface of the mine tunneling face for transport and transfer. Next, the exhaust fan 8 is started to draw air from the inside of the first dust removal tank 9, creating a negative pressure inside. This allows dusty air from the mine tunneling face to flow into the lower part of the first dust removal tank 9 through the air inlet 15. Since the first dust removal tank 9 has a large-pore filter 16, a small-pore filter 17, and an activated carbon filter 18 installed sequentially from bottom to top, the dusty air is filtered in stages by these filters. The exhaust fan 8 then connects to the air supply pipe 11. Pipeline 13 transports the filtered air from inside the first dust collector 9 to the water source 14 inside the second dust collector 10, allowing the remaining particulate matter in the air to dissolve in the water source 14, thus performing secondary filtration and purification of the air. This ensures the dust removal efficiency of the dust removal device for the mine tunneling face. Finally, by placing the exhaust fan 8 at the top of the base 1 between the first dust collector 9 and the second dust collector 10, and with the exhaust pipe 11 and the air supply pipe 13 located between the first dust collector 9 and the second dust collector 10, when air flows from inside the first dust collector 9 into the exhaust pipe 11, the exhaust fan 8, and the air supply pipe 13, the air has already been filtered in stages by the large-pore filter 16, the small-pore filter 17, and the activated carbon filter 18 inside the first dust collector 9. This reduces the phenomenon of large particulate matter flowing into the exhaust fan 8 and causing blockage, thereby completing the use of the dust removal device.
