[0029] like Figures 1 to 4 As shown, this application provides a coal powder collection and processing device for coal powder processing, the device comprising:

[0030] Two support plates 1;

[0031] A cylindrical cylinder 101 is fixedly mounted on the top of two support plates 1, and a bearing 108 is fixedly embedded in the inner wall of the cylindrical cylinder 101.

[0032] A fixing plate 102 is fixedly disposed on the outer surface of one of the support plates 1, and a long plate 103 is fixedly connected to the top of the fixing plate 102;

[0033] The servo motor 104 is fixedly mounted on the top of the long plate 103, and the output shaft of the servo motor 104 is fixedly embedded inside the bearing 108.

[0034] The screening cylinder 109 is fixedly connected to the output end of the servo motor 104;

[0035] Multiple holes 107 are formed on the outer surface of the screening cylinder 109.

[0036] like Figures 1 to 4 As shown, two hollow plates 201 are fixedly connected to the outer surface of the cylinder 101. A sealing door 105 is connected to the outer surface of the cylinder 101 by a hinge. A handle 106 is provided on one side of the outer surface of the sealing door 105 for easy opening.

[0037] like Figures 1 to 4 As shown, threaded rods 202 are movably connected to both sides of the inner wall of one hollow plate 201, and limit posts 204 are fixedly connected to both sides of the inner wall of the other hollow plate 201. The limit posts 204 limit the scraper 205 to prevent the scraper 205 from spinning freely.

[0038] like Figures 1 to 4 As shown, a rotary motor 2 is fixedly installed at one end of the cylinder 101. The output end of the rotary motor 2 is fixedly connected to one end of the threaded rod 202. The rotary motor 2 gradually drives the threaded rod 202 to rotate in the forward direction.

[0039] like Figures 1 to 4 As shown, multiple dustproof plates 203 are fixedly connected to the inner wall of the cylinder 101 to prevent coal dust from jamming the threaded rod 202.

[0040] like Figures 1 to 4 As shown, a scraper 205 is threadedly connected to the outer surface of the threaded rod 202. The scraper 205 quickly scrapes the screened coal powder into the container.

[0041] like Figures 1 to 4 As shown, the scraper 205 is movably sleeved on the outer surface of the limiting post 204 for easy positioning.

[0042] like Figures 1 to 4 As shown, the scraper 205 is internally and movably embedded on the outer surface of multiple dustproof plates 203 to facilitate scraping out coal dust.

[0043] In use, firstly, the coal powder to be screened is poured into the interior of the screening cylinder 109 through the hidden door at one end of the screening cylinder 109. Then, the sealing door 105 is closed. Subsequently, the external power supply of the servo motor 104 is turned on, and the servo motor 104 is started using the controller. The output end of the servo motor 104 drives the screening cylinder 109 to rotate at high speed. The coal powder in the screening cylinder 109 is subjected to centrifugal force due to the high-speed rotation, allowing it to quickly pass through the holes 107 on the surface of the screening cylinder 109. The aperture of the holes 107 is 0.5 mm. Therefore, through the high-speed rotation of the screening cylinder 109, the coal powder is quickly screened into the cylinder 101, thereby achieving better screening of coal powder. The structure is simple and easy to operate, making the coal powder screening... The screening process is more uniform, improving the overall efficiency of coal powder collection and processing. After screening, the staff opens the sealed door 105, places a collection container under the cylinder 101, and then turns on the external power supply of the rotating motor 2. The rotating motor 2 is started using the controller, and the rotating motor 2 gradually drives the threaded rod 202 to rotate forward. While the threaded rod 202 rotates forward, it drives the scraper 205 to gradually move from one side of the inner wall of the cylinder 101 to the other side. At this time, the limiting post 204 limits the scraper 205 to prevent the scraper 205 from spinning idly. The scraper 205 quickly scrapes the screened coal powder into the container, so that the coal powder can be discharged quickly after screening, improving the practicality of the coal powder collection and processing device.

[0044] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
