[0034] In this embodiment, the horizontal tubes 3-5 on both sides of the pump tube 1 have a suction function on one side and a liquid discharge function on the other side. During use, when residue and sludge accumulate in the pump tube 1, the driving motor 3-2 drives the driving shaft 3-3 to rotate, and the conveying auger 3-4 rotates in the pump tube 1. At this time, the conveying auger 3-4 cleans the pump tube 1.
