[0020] like Figure 3 As shown, the separation mechanism includes two water inlet hoses 17, which are fixedly connected to the outer surface of the pressure stabilizing tank 16, and a plurality of nozzles 19 are fixedly connected to the inner surface of the pressure stabilizing tank 16. The pressure stabilizing tank 16 can stabilize the water in the water inlet hoses 17, so that the water pressure sprayed by the nozzles 19 is more stable.

[0021] like Figure 1 and Figure 2 As shown, the spiral mechanism includes a positioning rod 12, which is fixedly connected to the inner surface of the circular ring plate 11, and the outer surface of the positioning rod 12 is fixedly connected to a spiral plate 13.

[0023] Working principle: This equipment is a raw coal desludging device. When in use, the raw coal is introduced into the feeding device 9, and then enters the drum 8. The motor 3 on the support plate 2 is started. The motor 3 drives the shaft 4 to rotate through the output shaft. The shaft 4 drives one of the gears 2 6 to rotate.

Due to the spiral plate 1 3 and the thrust generated by the rotation of the drum 8, the material will be gradually lifted or moved along the spiral direction, so that even if the spiral plate 13 itself does not rotate, the friction between the material and the drum 8 and the rotational power of the drum 8 drive the material to move forward, thereby realizing continuous movement of the material. The filter holes 15 on the drum 8 can screen the material, and then the water source of the two water inlet hoses 17 is connected, and the water source enters the pressure stabilizing header 16 through the water inlet hoses 17, and the pressure is stabilized in the pressure stabilizing header 16. Multiple nozzles 19 can spray water in the pressure stabilizing header 16 to clean the filter holes 15 on the drum 8, and the bristles 18 on the two fixed plates 1 can perform contact cleaning on the filter holes 15 on the drum 8.
