[0033] Working principle: During operation, fly ash and water are poured into tank 1. Then, the left-side cylinder 8 is activated, causing the second sealing cover 15 to descend until it covers the top of tank 1. The second motor 16 is activated, driving the rotating rod 17 to rotate. The rotating rod 17 drives the stirring rod 18 and the grooved plate 19 to rotate, stirring the fly ash and water. At the same time, the grooved plate 19 and the scraper 21 rotate, cleaning the inner wall of tank 1 and preventing fly ash from adhering to the inner wall. The extension and retraction of the spring 20 causes the scraper 21 to extend and retract within the groove of the grooved plate 19, ensuring that the scraper 21 remains in contact with the inner wall of tank 1. After stirring, the cylinder 8 drives the second sealing cover 15 to rise, causing the stirred fly ash and water to settle and separate. Simultaneously, the first motor 6 is activated, driving the threaded rod 5 to rotate, which in turn drives the moving rod 18 to rotate. The moving seat 7 moves to the left along the mounting groove 4 until the first sealing cover 9 moves to the top of the tank 1. After sedimentation, until all the fly ash settles to the bottom of the tank 1, the cylinder 8 is started to drive the first sealing cover 9 to descend. The electric push rod 10 drives the filter plate 11 to move down. The filter plate 11 separates water and fly ash. The fly ash will be isolated below the filter plate 11, thereby improving the separation speed of fly ash and water. Finally, the first water pump 12 is started to draw the water above out through the water pipe 13. Then the electric valve (not shown in the figure) is opened, and the fly ash is discharged from the tank 1 through the screw conveyor 29. When it is necessary to clean the inside of the tank 1, the second water pump 25 is started to draw the water in the water tank 24 into the diversion ring 22 through the water pipe 26. Finally, the water is sprayed out through the nozzle 23 to clean the inner wall of the tank 1.
