[0020] It is worth noting that, through the coordinated arrangement of the slurry pump volute 5, the discharge pipe 15, the mixed flow channel 16, the high-solid liquid connecting pipe 17 and the high-solid liquid diversion channel 20 structure, the pump utilizes the rotation of the impeller, the blades do not contact the solid particles, stir the solid and liquid to perform high-speed circular motion, and utilizes one pump with multiple channels to achieve rapid passage of solid slag, thereby reducing the circulation of solids in the pump, thereby clogging the pump and damaging the blades.
[0021] Specifically, the inner walls at both ends of the discharge pipe 15 are connected with annular stop blocks 22, and the outer surface of the spiral guide wheel 23 is provided with an annular groove, and the inner wall of the annular groove is rotatably connected to the surface of the annular stop block 22.

During the slurry transportation process, the spiral guide wheel 23 can cooperate with the annular limit block 22 to rotate, which can ensure the transportation efficiency and reduce the occurrence of blockage, and can move and rotate the slurry. In conjunction with the slurry pump impeller 8 inside the slurry pump volute 5, the slurry can be circulated and rotated quickly, so that the solid slag can pass through the pump quickly, reducing the occurrence of pump blockage and damage to the blades.
