[0021] The free end pipe of the second sleeve pipe 2 is detachably installed with the basket 4, the basket 4 is clamped on the port position of the second sleeve pipe 2 through the clamping piece, and the first sleeve pipe 1 and the second sleeve pipe 2 correspondingly have flanges at the free ends.

[0022] In order to prevent the impurities in the sludge pump from being sucked into the sludge pump during work, causing the pump body to be paralyzed, a filter pipe is installed on the suction pipe side of the sludge pump, the filter pipe is installed with a basket at the second sleeve pipe corresponding to the free end, which is used for filtering the plastic bags, plant vines and other shaped impurities in the sludge water during suction. The impurities will be accumulated in the basket, which will cause the pipe to be blocked if not cleaned for a long time. The utility model can deform the corrugated pipe by lifting the second sleeve pipe and forcing the corrugated pipe to deform without moving the sludge pump, so that the second sleeve pipe is upward, which is convenient for dismounting the basket to clean the impurities.

[0023] As shown in 1: the basket 4 is a barrel structure, the opening side of the second sleeve pipe 2 is an opening side, the opening side is provided with a supporting ring 41, the supporting ring 41 is annular and aligned with the opening side of the second sleeve pipe 2, and the corresponding side wall of the basket 4 is sleeved and installed on the second sleeve pipe 2.
