A transverse mud delivery pipe 5 is arranged on the upper end of the connecting bracket 3, and one end of the mud delivery pipe 5 is bent downward and extends into the mud discharge tank 24. The mud suction component 4 absorbs the sludge in the sedimentation tank and transports it to the mud discharge tank 24 through the mud delivery pipe 5. After that, the sludge in the mud discharge tank 24 is loaded and transported before other treatment;

[0022] The mud suction assembly 4 includes a mud suction pump 7, a mud collecting plate 8, a mud suction pipe 9 and a bypass pipeline 10.

The connecting cross bar 22 makes the overall structure of the mud gathering plate 8 more stable.

[0030] Working principle: When the utility model is working, the sludge in the sedimentation tank 6 is sucked by the sludge pump 7, and then enters the sludge discharge tank 24 through the sludge suction pipe 9, the second connecting pipe 14, the first connecting pipe 12 and the sludge delivery pipe 5. By setting a bypass pipe 10 on the first connecting pipe 12 and the second connecting pipe 14, after the sludge suction pump 7 is started, the sludge is sucked from the sludge suction pipe 9 by the sludge suction pump 7, and then enters the sludge discharge tank 24 through the second connecting pipe 12 and the sludge delivery pipe 5. After the sludge suction pump 7 has been running for a period of time, the sludge suction pump 7 is turned off. Because the lower port of the sludge suction pipe 9 is higher than the sludge discharge port of the sludge delivery pipe 5, according to the siphon principle, the sludge in the sedimentation tank is The sludge can continue to be discharged from the pipeline formed by the sludge suction pipe 9, the first connecting pipe 12, the bypass pipeline 10, the second connecting pipe 14 and the sludge delivery pipe 5, thereby avoiding the blockage caused by the impeller of the sludge pump 4 being entangled by fibers, hair and other materials during long-term working state, and saving electricity; the one-way valve 15 on the bypass pipeline 10 can prevent the sludge from flowing back; when the mud collecting plate 8 moves with the working bridge 1, the sludge can be collected near the sludge suction pipe 9, making the sludge suction work more comprehensive; the bypass pipeline 10 is connected to the first connecting pipe 12 and the second connecting pipe 14 by a three-way joint 20, which is convenient for disassembly and replacement.
