[0002] In the field of coalbed methane extraction, coal dust removal devices are essential for filtering coal dust from the gas. However, existing coalbed methane extraction devices are not convenient for scraping and cleaning the filter structure. After long-term use, a large amount of residue will remain, reducing the practicality of the coal dust removal devices. The existing devices also have some shortcomings; for example,

[0003] For example, a coalbed methane development anti-coal dust device, as described in announcement number CN219615143U, includes a base with two upright plates fixedly installed on its top. A housing is fixedly installed on the top of each upright plate. A collection frame is movably installed on the top of the base. A filter plate is fixedly installed inside the housing, and an installation box is fixedly installed on the top of the housing. An air inlet pipe extending to the left side of the inner wall of the housing is fixedly installed, and a dustproof net is fixedly installed on the inner side of the air inlet pipe. This device has some problems. While it can effectively filter coal dust, it typically only filters through the filter screen. When the coal dust content is too high, frequent filtration of the filter screen is required, making it difficult to achieve the desired effect. Therefore, we propose a coalbed methane development anti-coal dust device to solve the aforementioned problems. Summary of the Invention

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution for a coalbed methane extraction device to prevent coal dust, comprising a body 1, a cover 2 threadedly connected to the body 1, a water tank 3 located above the body 1, and the water tank 3 connected to atomizing nozzles 4. The atomizing nozzles 4 are arranged in an array inside the body 1, and each atomizing nozzle 4 is connected to a water pump located inside the water tank 3 above the body 1. A sedimentation tank 5 and a filter plate 6 are located inside the body 1, and the body 1 is connected to a brush plate 11 via a lifting mechanism. The lifting mechanism includes... The device includes a first motor 7, a rotating shaft 8, a first rotating rod 9, a threaded rod 10, and a brush plate 11. The first motor 7 is fixedly connected to the inside of the machine body 1, and the first motor 7 is connected to the rotating shaft 8. The rotating shaft 8 is connected to the first rotating rod 9, the first rotating rod 9 is slidably connected to the threaded rod 10, and the threaded rod 10 is threadedly connected to the inside of the machine body 1. The lower end of the threaded rod 10 is rotatably connected to the brush plate 11, the upper end of the brush plate 11 is fixedly connected to the support rod 12, and the upper end of the support rod 12 is slidably connected to the inside of the machine body 1. The first rotating rod 9 is a square rod.

[0020] During use, the machine is moved using the multiple casters at the bottom. After removing the cover 2, connect the machine body 1 to the gas pipeline for coalbed methane extraction. Then, start the multiple fans 13 inside the machine body 1 to draw air containing coal dust into the machine body 1. Simultaneously, start the multiple atomizing nozzles 4 inside the machine body 1. A water pump draws clean water from the water tank 3, which is then sprayed out through the atomizing nozzles 4. The atomizing nozzles 4 atomize the liquid into tiny water droplets, which mix with the airflow. The coal dust particles collide with and adhere to the water droplets, subsequently settling into the sedimentation tank 5 below. The settled air then... The filter plate 6 performs secondary filtration, filtering out residual coal dust in the air before discharge. If there is a lot of coal dust on the filter plate 6 during use, the filtration effect may be reduced. In this case, the first motor 7 inside the machine body 1 can be started to drive the rotating shaft 8 to rotate, which in turn drives the first rotating rod 9 to rotate. The first rotating rod 9 drives the threaded rod 10 to rotate, and the threaded rod 10 rotates inside the machine body 1 through the thread. The threaded rod 10 then drives the brush plate 11 below to descend. The brush plate 11 drives the support rod 12 to slide inside the machine body 1, and the brush plate 11 cleans the surface of the filter plate 6.

[0021] The body 1 is fixedly connected to the push rod 14, and the front end of the push rod 14 is fixedly connected to the push plate 15. The body 1 is connected to the drain pipe 16, and the drain pipe 16 is slidably connected to the baffle 17. The drain pipe 16 is equipped with a drain mechanism, which includes the drain pipe 16, the second motor 18, the second rotating rod 19, and the rotating plate 20. The drain pipe 16 is fixedly connected to the second motor 18, and the second motor 18 is connected to the second rotating rod 19. The surface of the second rotating rod 19 is fixedly connected to the rotating plate 20. The rotating plate 20 is arranged in an array about the surface of the second rotating rod 19. The body 1 is equipped with a fan 13, which is arranged in an array about the inside of the body 1. The body 1 is equipped with casters at the bottom, and the casters are symmetrical about the center of the body 1.

[0022] The residual coal powder on the surface is brushed into the sedimentation tank 5 below. The sedimentation tank 5 needs to be cleaned of coal powder regularly. After the baffle 17 above the drain pipe 16 on one side is pulled out, the push rod 14 inside the machine body 1 is started to drive the push plate 15 to move inside the sedimentation tank 5. The coal powder settled at the bottom of the tank is pushed into the drain pipe 16 on one side. At the same time, the second motor 18 inside the drain pipe 16 is started to drive the second rotating rod 19 to rotate. The second rotating rod 19 drives the multiple rotating plates 20 on the surface to rotate. At this time, the rotation of the multiple rotating plates 20 can promote the discharge of coal powder and prevent the drain pipe 16 from becoming blocked.

[0023] Working Principle: When using the coalbed methane extraction and coal dust prevention device, after moving it using the multiple casters at the bottom, rotate cover 2 to remove it, and connect the machine body 1 to the gas pipeline of the coalbed methane extraction. At this time, start the multiple fans 13 inside the machine body 1 to draw air containing coal dust into the machine body 1. Then, start the multiple atomizing nozzles 4 inside the machine body 1. The water pump draws clean water from the water tank 3 and sprays it out through the atomizing nozzles 4. The atomizing nozzles 4 spray the liquid into tiny water droplets, which mix with the airflow. The coal dust particles collide with the water droplets and adhere to the water droplets, and then settle into the sedimentation tank 5 below. The settled air is filtered a second time through the filter plate 6 to filter out the residual coal dust in the air before being discharged. If there is a lot of coal dust above the filter plate 6 during use, the filtration effect may be poor. At this time, the first motor 7 inside the machine body 1 can be started to drive the rotating shaft 8 to rotate, so that the rotating shaft 8 drives the first rotating rod 9 to rotate, and the first rotating rod 9 drives the threaded rod 10 to rotate. The rotation causes the threaded rod 10 to rotate inside the machine body 1 via the thread. The threaded rod 10 then drives the brush plate 11 below to descend. The brush plate 11 drives the support rod 12 to slide inside the machine body 1, and the brush plate 11 cleans the surface of the filter plate 6, brushing the residual coal powder on the surface into the sedimentation tank 5 below. The sedimentation tank 5 needs to be cleaned of the coal powder inside regularly. After the baffle 17 above the drain pipe 16 on one side is pulled out, the push rod 14 inside the machine body 1 is activated to drive the push plate 15 to move inside the sedimentation tank 5, pushing the coal powder settled at the bottom of the tank into the drain pipe 16 on one side. At the same time, the second motor 18 inside the drain pipe 16 is activated to drive the second rotating rod 19 to rotate, so that the second rotating rod 19 drives the multiple rotating plates 20 on the surface to rotate. At this time, the rotation of the multiple rotating plates 20 can promote the discharge of coal powder and prevent blockage inside the drain pipe 16, thereby completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
