Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to a dust reduction device for continuous coal mining. Background Technology

[0002] Coal mines are areas where humans extract coal resources in coal-rich areas, generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, underground tunnels are typically dug to extract the coal; this is called an underground coal mine. When the coal seam is very close to the surface, the surface soil layer is typically stripped away to extract the coal; this is called an open-pit coal mine. During continuous coal mining operations, a large amount of dust is generated. To ensure safety, dust suppression devices are usually used for dust control.

[0003] In existing technologies, such as the Chinese patent with publication number CN213144528U entitled "A Dust Suppression Device for Continuous Coal Mining," the disclosed technical solution describes that during dust suppression operation, a drive motor is started, which drives a turntable to rotate, thereby causing a fixed column to rotate. The fixed column reciprocates within the sliding cavity of the connecting frame, which in turn drives the connecting frame to move up and down. During the up-and-down movement of the connecting frame, the connecting rod moves, thereby enabling the cleaning ring to clean the dust collected on the outer edge of the filter screen. However, the cleaning ring can only clean the filter screen after the dust extraction process has been stopped, which has certain limitations. Utility Model Content

[0004] This utility model provides a dust suppression device for continuous coal mining to solve the above-mentioned problems.

[0005] This utility model adopts the following technical solution: a dust suppression device for continuous coal mining, comprising a U-shaped support pipe with its opening facing downwards; the lower end of the support pipe is fixed to the ground, forming an arch structure; the upper end of the support pipe is provided with a downward-facing exhaust port, and the lower end is provided with an air inlet; a filter cylinder is provided inside the support pipe; the filter cylinder is vertically arranged, with its lower end fixed to the upper end of the exhaust port; a sealing plate is provided at the upper end of the filter cylinder; the sealing plate is rotatably installed on the inner wall of the support pipe and rotatably cooperates with the upper end of the filter cylinder; the sealing plate seals the upper end of the filter cylinder; the sealing plate is driven by a power mechanism to achieve rotation;

[0006] A cleaning mechanism is provided between the sealing disc and the filter cartridge; multiple cleaning mechanisms are evenly distributed around the circumference of the sealing disc; the cleaning mechanism includes an outer partition plate and an inner partition plate; the outer partition plate is located on the outside of the filter cartridge and its upper end is fixed to the sealing disc; a cleaning groove with an opening facing the filter cartridge is provided on the side wall of the outer partition plate near the filter cartridge; a dust-sweeping component is provided in the cleaning groove; the dust-sweeping component is used to clean the outer wall of the filter cartridge when the sealing disc rotates; a dust-collecting component is provided at the lower end of the cleaning groove; the dust-collecting component is located on the side of the dust-sweeping component away from the filter cartridge;

[0007] An inner partition plate is located inside the filter cartridge and its upper end is fixed to the sealing disc. An auxiliary groove with an opening facing the filter cartridge is provided on the side wall of the inner partition plate near the filter cartridge. The inner partition plate and the filter cartridge abut against each other. The auxiliary groove and the cleaning groove form a sealed cleaning chamber. Multiple cleaning chambers are spaced apart, dividing the filter cartridge into alternating filtration and cleaning zones. During the rotation of the sealing disc by the power mechanism, the filter cartridge's filtration zone filters, and the dust-sweeping component cleans the filter cartridge's cleaning zone, achieving simultaneous filtration and cleaning. Simultaneously, as the sealing disc rotates, the filter cartridge's filtration and cleaning zones alternate, ensuring the filter cartridge maintains high filtration efficiency and improving dust removal efficiency. An auxiliary component is provided inside the auxiliary groove. This component periodically backflushes air from the inside to the outside of the filter cartridge when the sealing disc rotates, blowing the dust swept down by the dust-sweeping component towards the dust collection component.

[0008] Furthermore, the dust removal assembly includes a dust removal roller and a mating ring;

[0009] The fitting ring is coaxially fixed to the upper end of the filter cartridge;

[0010] The dust-sweeping roller is located inside the cleaning trough; its axis is vertically aligned and it is rotatably mounted on the trough wall via a rotating shaft; the roller is equipped with bristles; these bristles abut against the outer wall of the filter cartridge; a drive wheel is fixed to the upper end of the roller's rotating shaft; the drive wheel and a mating ring engage for transmission. The sealing disc drives the outer partition plate to rotate, and the outer partition plate, through the cleaning trough, causes the dust-sweeping roller to revolve around the filter cartridge axis. Due to the engagement of the drive wheel and the mating ring, the dust-sweeping roller rotates on its own axis while revolving around the filter cartridge axis, thus cleaning the dust on the outer surface of the filter cartridge.

[0011] Furthermore, the auxiliary components include an auxiliary plate and an auxiliary structure; the auxiliary plate is slidably installed in the auxiliary groove along the radial direction of the filter cartridge; an auxiliary spring is connected between the auxiliary plate and the groove wall of the auxiliary groove; the auxiliary structure is used to periodically provide a pulling force away from the filter cartridge to the auxiliary plate when the sealing disc rotates, so that the auxiliary spring stores force. When the spring force of the auxiliary spring is greater than the pulling force, the auxiliary spring releases force to drive the auxiliary plate to move towards the filter cartridge, so as to blow the air in the auxiliary groove from the inside of the filter cartridge to the outside of the filter cartridge, and blow the dust on the bristles of the cleaning roller towards the dust collection assembly.

[0012] Furthermore, the auxiliary structure includes a pull rod and a pull plate; the pull plate is located on the side of the inner partition plate away from the filter cartridge; the pull plate is vertically installed, and its lower end is fixed to the inner wall of the exhaust port by a connecting rod; the horizontal cross-section of the pull plate is an arc shape protruding towards the filter cartridge; the pull plate is magnetic.

[0013] The pull rod is radially positioned between the pull plate and the auxiliary plate of the filter cartridge. It is slidably mounted on the inner partition plate. One end of the pull rod is fixed to the auxiliary plate, while the other end is magnetic, with the magnetic poles opposite to those of the pull plate. When the pull rod rotates with the inner partition plate to the pull plate, the pull plate and pull rod are magnetically attracted. As the pull rod rotates away, it slides along the arc surface of the pull plate under magnetic force, pulling the auxiliary plate away from the filter cartridge. The auxiliary spring stores energy; when the magnetic force is less than the spring force, the pull plate and pull rod disengage, and the auxiliary spring releases its force, causing the auxiliary plate to move towards the filter cartridge. This reverses the air flow from the inside of the filter cartridge to the outside, blowing dust from the brush bristles of the cleaning roller towards the dust collection assembly.

[0014] Furthermore, the dust collection assembly includes a dust collection hole and a dust collection box; the dust collection hole is located at the lower end of the cleaning groove and on the side of the sweeping roller away from the filter cartridge; the dust collection box is installed at the lower end of the outer partition plate and is connected to the cleaning groove through the dust collection hole. An auxiliary spring releases force to move an auxiliary plate towards the filter cartridge, thereby blowing air from the inside of the filter cartridge to the outside, blowing dust from the brush bristles of the sweeping roller towards the dust collection hole, and causing it to fall into the dust collection box.

[0015] Furthermore, the ash collection box is slidably installed along the radial direction of the filter cartridge at the lower end of the outer partition plate; a cleaning door is provided at the corresponding position on the support pipe; the cleaning door screws are fastened to the support pipe. When it is necessary to clean the ash collection box, open the cleaning door and remove the ash collection box for cleaning.

[0016] Furthermore, the power mechanism includes a power motor; the power motor is fixed on the outer wall of the support tube; the output shaft of the power motor is fixedly connected to the sealing disc.

[0017] The beneficial effects are:

[0018] 1. During the process of the power mechanism driving the sealing disc to rotate the cleaning mechanism, the filter cartridge's filtration zone filters, and the dust removal component cleans the filter cartridge's cleaning zone, achieving simultaneous filtration and cleaning of the filter cartridge. At the same time, as the sealing disc rotates, the filter cartridge's filtration zone and cleaning zone alternate, ensuring that the filter cartridge always maintains a high filtration efficiency and improving dust removal efficiency.

[0019] 2. When the sealing disc rotates, the auxiliary component periodically back-blowing air from the inside to the outside of the filter cartridge, blowing the dust swept down by the dust sweeping component towards the dust collection component, promoting the cleaning of the filter cartridge and improving dust removal efficiency.

The sealing disc 300 drives the outer partition plate 410 to rotate, and the outer partition plate 410 drives the dust removal roller 411 to revolve around the axis of the filter cartridge 200 through the cleaning groove. Due to the meshing transmission of the transmission wheel and the mating ring 412, the dust removal roller 411 rotates around its own axis while revolving around the axis of the filter cartridge 200, so as to clean the dust on the outer surface of the filter cartridge 200.

[0034] A dust collection component is provided at the lower end of the cleaning tank; the dust collection component is located on the side of the dust sweeping component away from the filter cartridge 200;

[0035] An inner partition plate 420 is located inside the filter cartridge 200, with its upper end fixed to the sealing disc 300. An auxiliary groove with an opening facing the filter cartridge 200 is provided on the side wall of the inner partition plate 420 near the filter cartridge 200. The inner partition plate 420 abuts against the filter cartridge 200. The auxiliary groove and the cleaning groove form a sealed cleaning chamber. Multiple cleaning chambers of the cleaning mechanism are spaced apart, dividing the filter cartridge 200 into alternating filtration and cleaning zones. During the rotation of the sealing disc 300 by the power mechanism, the filtration zone of the filter cartridge 200 performs filtration, and the dust removal component cleans the cleaning zone of the filter cartridge 200, achieving simultaneous filtration and cleaning of the filter cartridge 200. Simultaneously, as the sealing disc 300 rotates, the filtration and cleaning zones of the filter cartridge 200 alternate, ensuring the filter cartridge 200 maintains a high filtration efficiency and improving dust removal efficiency. An auxiliary component is provided inside the auxiliary groove.

[0036] The auxiliary component is used to periodically backflush air from the inside to the outside of the filter cartridge 200 when the sealing disc 300 rotates, blowing the dust swept by the dust removal component towards the dust collection component. The auxiliary component includes an auxiliary plate 421 and an auxiliary structure; the auxiliary plate 421 is slidably installed in the auxiliary groove along the radial direction of the filter cartridge 200; an auxiliary spring is connected between the auxiliary plate 421 and the groove wall of the auxiliary groove; the auxiliary structure is used to periodically provide a pulling force away from the filter cartridge 200 to the auxiliary plate 421 when the sealing disc 300 rotates, so that the auxiliary spring stores force. When the spring force of the auxiliary spring is greater than the pulling force, the auxiliary spring releases force to drive the auxiliary plate 421 to move towards the filter cartridge 200, so as to backflush air in the auxiliary groove from the inside to the outside of the filter cartridge 200, blowing the dust on the brush bristles of the cleaning roller towards the dust collection component. The auxiliary structure includes a pull rod 422 and a pull plate 423; the pull plate 423 is located on the side of the inner partition plate 420 away from the filter cartridge 200; the pull plate 423 is vertically arranged, and its lower end is fixed to the inner wall of the exhaust port 110 by a connecting rod; the horizontal cross section of the pull plate 423 is an arc shape protruding towards the filter cartridge 200; the pull plate 423 is magnetic.

[0037] A pull rod 422 is radially disposed between a pull plate 423 and an auxiliary plate 421 along the filter cartridge 200; the pull rod 422 is slidably mounted on the inner partition plate 420; one end of the pull rod 422 is fixed to the auxiliary plate 421, and the other end is magnetic, with the magnetic pole opposite to that of the pull plate 423. When the pull rod 422 rotates with the inner partition plate 420 to the pull plate 423, the pull plate 423 and the pull rod 422 are magnetically attracted. As the pull rod 422 rotates away, under the magnetic force, the pull rod 422 slides along the arc surface of the pull plate 423 and pulls the auxiliary plate 421 away from the filter cylinder 200 through the pull rod 422. The auxiliary spring stores force. When the magnetic force is less than the elastic force of the auxiliary spring, the pull plate 423 and the pull rod 422 separate. The auxiliary spring releases force and drives the auxiliary plate 421 to move towards the filter cylinder 200, so as to blow the air in the auxiliary groove from the inside of the filter cylinder 200 to the outside of the filter cylinder 200, and blow the dust on the brush bristles of the cleaning roller towards the dust collection assembly.

[0038] In this embodiment, the dust collection assembly includes a dust collection hole 431 and a dust collection box 432. The dust collection hole 431 is located at the lower end of the cleaning groove and on the side of the sweeping roller 411 away from the filter cartridge 200. The dust collection box 432 is installed at the lower end of the outer partition plate 410 and is connected to the cleaning groove through the dust collection hole 431. An auxiliary spring releases force to move the auxiliary plate 421 toward the filter cartridge 200, so as to blow the air in the auxiliary groove from the inside of the filter cartridge 200 to the outside of the filter cartridge 200, blowing the dust on the brush bristles of the sweeping roller toward the dust collection hole 431, and falling into the dust collection box 432 through the dust collection hole 431. The dust collection box 432 is slidably installed at the lower end of the outer partition plate 410 along the radial direction of the filter cartridge 200. A cleaning door 130 is provided at the corresponding position on the support tube 100. The cleaning door 130 is screwed onto the support tube 100. When it is necessary to clean the dust collection box 432, the cleaning door 130 is opened and the dust collection box 432 is removed for cleaning.

[0039] Based on the above embodiments, the working principle and process of this utility model are as follows: During continuous coal mining, the exhaust fan and the power motor 310 are started simultaneously, and the air mixed with dust in the mine enters the support pipe 100 through the air inlet 120. After being filtered by the filter cylinder 200, it is discharged from the exhaust port 110, and the dust is filtered onto the outer wall of the filter cylinder 200.

[0040] The power motor 310 drives the sealing disc 300 to rotate. The sealing disc 300 drives the outer partition plate 410 to rotate, and at the same time drives the inner partition plate 420 to rotate. The outer partition plate 410 drives the dust sweeping roller 411 to revolve around the axis of the filter cartridge 200 through the cleaning groove. Due to the meshing transmission wheel and the mating ring 412, the dust sweeping roller 411 rotates around its own axis while revolving around the axis of the filter cartridge 200, so as to clean the dust on the outer surface of the filter cartridge 200.

[0041] The inner partition plate 420 drives the pull rod 422 to rotate. When the pull rod 422 rotates with the inner partition plate 420 to the pull plate 423, the pull plate 423 and the pull rod 422 are magnetically attracted. As the pull rod 422 rotates away, under the magnetic force, the pull rod 422 slides along the arc surface of the pull plate 423, pulling the auxiliary plate 421 away from the filter cartridge 200 via the pull rod 422. The auxiliary spring stores force. When the magnetic force is less than the elastic force of the auxiliary spring, the pull plate 423 and the pull rod 422 separate. The auxiliary spring releases force, driving the auxiliary plate 421 to move towards the filter cartridge 200, so as to blow the air in the auxiliary groove from the inside of the filter cartridge 200 to the outside of the filter cartridge 200, blowing the dust on the brush bristles of the cleaning roller towards the dust collection hole 431, and falling into the dust collection box 432 through the dust collection hole 431. When it is necessary to clean the dust collection box 432, the cleaning door 130 is opened and the dust collection box 432 is removed for cleaning. The filter cartridge 200 performs filtration in its filtration zone and cleans its cleaning zone using a dust removal component, enabling simultaneous filtration and cleaning. Simultaneously, as the sealing disc 300 rotates, the filtration and cleaning zones of the filter cartridge 200 alternate, ensuring the filter cartridge 200 maintains high filtration efficiency and improving dust removal efficiency.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
