[0023] Please see Figures 1-5 As shown, a coal washing tank for coal processing.

[0024] The system includes a water tank 2, with an inlet pipe 1 fixedly connected to the left end of the water tank 2. A partition plate 23 is fixedly connected inside the water tank 2. A cleaning pool 10 is fixedly connected to the right end of the water tank 2. An inclined plate 22 is fixedly connected to the left side of the cleaning pool 10. Linearly distributed protrusions 21 are fixedly connected to the lower surface of the cleaning pool 10. A rotating shaft 13 is rotatably connected inside the cleaning pool 10, with both ends of the rotating shaft 13 penetrating the surface of the cleaning pool 10. Limiting wheels 11 are fixedly connected to both ends of the outer surface of the rotating shaft 13. A stirring plate 12 is fixedly connected inside each of the two limiting wheels 11. A first gear 19 is fixedly connected to one end of the rotating shaft 13. A support plate 17 is fixedly connected to the back of the cleaning pool 10. A motor 18 is fixedly connected to the upper surface of the support plate 17. A second gear 20 is fixedly connected to the output end of the motor 18 through a coupling. The outer surface of the second gear 20 meshes with the outer surface of the first gear 19, thus utilizing the [function / function].

[0025] The washing tank 10 is internally connected to a separation plate 16, and a first separation groove 14 is fixedly connected to the upper surface of the separation plate 16. A second separation groove 15 is fixedly connected to the right side of the washing tank 10. The washing liquid is introduced into the water injection tank 2 through the water inlet pipe 1, and the washing liquid is divided by the partition plate 23, so that the washing liquid is evenly distributed inside the water injection tank 2 to wash the coal blocks entering the water injection tank 2. The washing liquid is a mixture of non-polar hydrocarbon oil, polyacrylamide, etc., which facilitates the cleaning of coal blocks and helps to separate the coal blocks. The washing liquid carries the coal blocks along the inclined plate. The water flow 22 is poured into the cleaning tank 10. The water flow at a certain speed impacts the protrusion 21, causing the cleaning liquid and coal block mixture at the bottom to impact upwards along the surface of the protrusion 21, increasing the impact force of the cleaning liquid on the coal block. Then, the motor 18 is turned on, causing the motor 18 to drive the second gear 20 to rotate through the coupling. Under the meshing action of the second gear 20 and the first gear 19, the rotating shaft 13 is driven to rotate, which in turn drives the stirring plate 12 to rotate, accelerating the stirring of the cleaning liquid and coal block mixture, thereby achieving the effect of quickly and thoroughly cleaning the impurities on the surface of the coal block.

[0026] Among them, the upper surface of the water injection tank 2 is fixedly connected to the feed box 3, and the surface of the feed box 3 is fixedly connected to four fixing blocks 6. The fixing blocks 6 are used to connect the position of the limiting link 5.

[0027] Each of the four fixed blocks 6 has a connecting rod 5 rotatably connected to one side, and each of the four connecting rods 5 has a screen hopper 4 rotatably connected to one side. The connecting rods 5 serve to connect and fix the screen hopper 4.

[0028] The lower surface of the screen hopper 4 is provided with filter holes 7, and a limit block 8 is fixedly connected to the lower surface of the screen hopper 4. The filter holes 7 are used to separate coal lumps that do not conform to the particle size and larger impurities.

[0029] Among them, the front of the feed box 3 is provided with an electric telescopic rod 9. The outer surface of the output end of the electric telescopic rod 9 is slidably connected to the inside of the limiting block 8. The electric telescopic rod 9 is used to facilitate the swinging of the screen bucket 4.

[0030] Working principle: Crushed coal is poured into the screen hopper 4. Coal pieces of the appropriate size pass through the filter holes 7 and enter the water tank 2. Larger coal pieces or impurities remain inside the screen hopper 4. The electric telescopic rod 9 is activated, causing the limiting block 8 to move with the screen hopper 4. The screen hopper 4 swings under the limiting action of the connecting rod 5, allowing the impurities remaining inside the screen hopper 4 to be discharged from one side. Then, cleaning fluid is introduced into the water tank 2 through the water inlet pipe 1. The cleaning fluid is divided and distributed inside the water tank 2 by the partition plate 23, rinsing the coal pieces entering the water tank 2. The coal pieces are then transferred to the cleaning pool 10. The mixture of coal and cleaning fluid... The coal blocks tumble against the surface of the protrusion 21, increasing the cleaning force on the surface of the coal. At the same time, the motor 18 is started, which drives the second gear 20 to mesh with the first gear 19. The first gear 19 drives the rotating shaft 13 to rotate. The limiting wheel 11 and the stirring plate 12, which are fixedly connected to the rotating shaft 13, stir the cleaning liquid and thoroughly clean the coal. The cleaned coal blocks enter the right side of the cleaning tank 10. According to the different densities of the coal blocks and impurities, they are separated into layers by the separation plate 16. The upper layer of coal blocks enters the first separation tank 14, and the bottom impurities enter the second separation tank 15, completing the cleaning and separation of the coal blocks.
