Problems solved by technology

[0004] However, the technical solution in this application document still has deficiencies. For example, if the shutdown time is a little longer, the blocky sludge in the pump will stick to the blade and harden, thereby hindering the starting of the motor, causing the sludge return pump to block, etc.

Abstract

The invention relates to an anti-clogging sludge return pump, comprising: an inner shell, an outer shell and a drive motor, wherein the inner shell is arranged in the outer shell; the drive motor comprises a drive shaft, The drive shaft extends from one side of the outer casing into the inner casing; the inner casing is provided with several groups of rotating impellers and cones, and a plurality of the rotating impellers are evenly sleeved in the inner casing. The length direction of the drive shaft, and the cone is arranged at the end of the drive shaft away from the drive motor, and the inner shell is located on the side of the cone with a sludge inlet pipe and an inlet sewage Tube. The anti-clogging sludge return pump shown in the present invention can solve the problem in the prior art that the lumpy sludge is bound to the rotating impeller and hardened, thereby hindering the starting of the driving motor, so that the sludge return pump can work smoothly and has a high degree of work automation. Wide application prospects.

Description

technical field [0001] The invention relates to the technical field of sludge return pumps, in particular to an anti-clogging sludge return pump. Background technique [0002] The sludge return pump is a conveying machine used to discharge high viscosity concentration. The sludge return pump is generally used for the transportation of sludge and papermaking sludge before dehydration treatment. The existing sludge return pump is used in the process of sewage treatment. Because the sludge is mixed with a lot of other garbage or lumpy sludge, if it accumulates inside the sludge return pump, it will easily cause blockage, thus affecting its normal rotation operation, and its structure is relatively fixed, which is inconvenient for sludge. The inside of the return pump is cleaned, and the operation process is cumbersome, resulting in low work efficiency. [0003] For this reason, those skilled in the relevant technical field have made improvements. For example, the Chinese paten...
