[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, a coal slime centrifugal dewatering and washing device includes: a pad plate 1, with a right fixed plate 102 and a left fixed plate 103 connected to the top of the pad plate 1, an outer shell 101 disposed between the right fixed plate 102 and the left fixed plate 103, an inner shell 104 disposed inside the outer shell 101, the inner shell 104 having multiple screen holes, and a cleaning component disposed inside the outer shell 101 for cleaning materials adhering to the inner wall of the outer shell 101. The cleaning component includes: a fixed plate 5, a connecting rod b501 and a scraper b502.

[0018] The cleaning assembly utilizes a fixed disc 5, connecting rod b501, and scraper b502. While the scraper a401 cleans the inner shell 104, the stirring rod 402 prevents coal slime from caking inside the equipment. The fixed disc 5 then drives the connecting rod b501 and scraper b502 to adhere to the inner wall of the outer shell 101, removing adhering materials and preventing material accumulation from affecting equipment operation. This ensures the efficiency of the centrifugal dewatering and washing of coal slime and guarantees the equipment's sustainable and stable operation.

[0019] Among them, a motor a2 is installed on the pad 1, and a transmission wheel a201 is driven and connected to one side of the motor a2. A transmission wheel b202 is provided on one side of the right fixed plate 102. A transmission belt 203 is provided between the transmission wheel a201 and the transmission wheel b202. A transmission shaft 204 is connected to one side of the transmission wheel b202. One end of the transmission shaft 204 extends into the outer shell 101 and is connected to one side of the inner shell 104. A fixed cover 3 is installed on one side of the left fixed plate 103. One side of the fixed cover 3 extends into the inner shell 104 and is rotatably connected to the inner shell 104. A motor b301 is installed on one side of the fixed cover 3. A rotating rod 302 is driven and connected to one side of the motor b301. One side of the rotating rod 302 passes through the fixed cover 3 and extends into the inner shell 104, where four connecting rods a4 are connected. A liquid inlet pipe 303 is provided on one side of the left fixed plate 103. One end of the liquid inlet pipe 303 passes through the fixed cover 3 and communicates with the inner shell 104.

[0020] Motor a2 is started, driving transmission shaft 204 to rotate through a transmission system consisting of transmission wheel a201, transmission belt 203, and transmission wheel b202. Transmission shaft 204 drives inner shell 104 to rotate at high speed. At the same time, motor b301 starts, driving rotating rod 302 to rotate. Rotating rod 302 drives two scrapers a401 and multiple stirring rods 402 to rotate synchronously. Under the action of centrifugal force, water is thrown out through the sieve holes on the wall of inner shell 104 and enters the interior of outer shell 101, while the dewatered coal slime is trapped in inner shell 104. The rotating scrapers a401 continuously scrape the inner wall of inner shell 104 to prevent clogging of sieve holes, while the stirring rods 402 stir and disperse the coal slime to prevent agglomeration.

[0021] Two scrapers a401 are provided between the four connecting rods a4. The two ends of the two scrapers a401 are connected to one end of the corresponding connecting rod a4. Multiple stirring rods 402 are connected to the outside of the rotating rod 302. A fixed disk 5 is connected to the outside of the drive shaft 204. The fixed disk 5 is rotatably connected to one side of the inner wall of the outer shell 101. An annular groove 503 is provided on the other side of the inner wall of the outer shell 101. Multiple balls are installed inside the annular groove 503. A sliding block 504 is provided inside the annular groove 503. The top of the sliding block 504 and the top of the fixed disk 5 are both connected to the connecting rod b501. A scraper b502 is connected between the two connecting rods b501. The scraper b502 is in contact with the inner wall of the outer shell 101. A connecting block 6 is connected to one side of the right fixed plate 102 and the left fixed plate 103. The other side of the connecting block 6 is connected to one side of the outer shell 101. A drainage frame 601 is connected to the bottom of the outer shell 101.

[0022] Furthermore, the rotation of the drive shaft 204 simultaneously drives the fixed disk 5 to rotate. The fixed disk 5 drives the scraper b502 through the connecting rod b501, while the connecting rod b501 at the other end of the scraper b502 slides in the annular groove 503 through the sliding block 504. By using ball bearings to reduce friction, the scraper b502 always remains in contact with the inner wall of the outer casing 101, scraping off the material adhering to the inner wall of the outer casing. The removed water is finally discharged through the drain frame 601.

[0023] Working principle: Motor a2 is started, and through the transmission system consisting of transmission wheel a201, transmission belt 203 and transmission wheel b202, the transmission shaft 204 is driven to rotate. The transmission shaft 204 drives the inner shell 104 to rotate at high speed. At the same time, motor b301 is started, driving the rotating rod 302 to rotate. The rotating rod 302 drives the two scrapers a401 and multiple stirring rods 402 to rotate synchronously.

[0024] Furthermore, under the action of centrifugal force, water is thrown out through the sieve holes on the inner shell 104 and enters the interior of the outer shell 101, while the dehydrated coal slurry is trapped in the inner shell 104. The rotating scraper a401 continuously scrapes the inner wall of the inner shell 104 to prevent the sieve holes from clogging. At the same time, the stirring rod 402 stirs and disperses the coal slurry to prevent agglomeration.

[0025] Furthermore, the rotation of the drive shaft 204 simultaneously drives the fixed disk 5 to rotate. The fixed disk 5 drives the scraper b502 through the connecting rod b501, while the connecting rod b501 at the other end of the scraper b502 slides in the annular groove 503 through the sliding block 504. By using ball bearings to reduce friction, the scraper b502 always remains in contact with the inner wall of the outer casing 101, scraping off the material adhering to the inner wall of the outer casing. The removed water is finally discharged through the drain frame 601.

[0026] In addition, all electrical components mentioned in the article are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the article.
