[0002] Sewage pump is a kind of centrifugal impurity pump, which has many forms: submersible and dry. The most commonly used submersible is QW submersible sewage pump. The most common dry sewage pumps are W horizontal sewage pump and WL vertical sewage pump. They are mainly used to transport urban sewage, but the medium being transported contains impurities such as mud and sand.
[0003] The sewage pump filter device with publication number CN209724702U has a roller and a cutter in front of the filter screen, a ratchet is provided on the outer circumference of the roller, and the cutter corresponds to the gap between the ratchet adjacent to the axial direction. When the sewage flows to the inlet of the sewage pump, it first passes through the roller, and the entangled or bunched materials are entangled on the ratchet. While the roller rotates, the entangled or bunched materials are continuously cut by the cutter until they are cut off by the cutter, and then fall off from the ratchet into the sewage. The cut pollutants are blocked outside the inlet of the sewage pump by the filter screen, and will not cause clogging of the filter screen. In addition, the existing filter device has the following disadvantages during use:
[0004] In the existing filtering device, impurities blocked by the filter net inside the cover cannot be collected and cleaned centrally, which will cause the impurities to clog the filter holes over time, resulting in dry pumping of the sewage pump and damage to the sewage pump, reducing the use effect of the filter net and increasing the maintenance cost of the sewage pump and the filter net.

The two crushing rollers 202 are driven to rotate in opposite directions through the transmission shaft, thereby crushing the impurities inside the sewage, so that large impurities are crushed into small impurities, which are convenient for centralized collection and treatment. The crushed impurities and sewage are transported to the inside of the filter box 5 together through the connecting pipe 1 4, and the connecting pipe 1 4 is abutted against the water inlet hole 601, so that the sewage and impurities are filtered through the filter basket 6, and the impurities are concentratedly collected in the filter basket 6, so that only the sewage is transported to the next process through the connecting pipe 2 10 and the sewage pump 11. When a certain degree of impurities are collected in the filter basket 6, the electric push rod 7 is started to lift the filter basket 6, and then the pressing plates 809 on both sides are pressed at the same time to drive the moving seat to slide similarly through the L-shaped push rod 808, thereby driving the L-shaped plug rod 805 to shrink to the middle, so that the U-shaped seat 9 is released, and the filter basket 6 is taken out, and the internal impurities are centrally processed and the filter basket 6 is cleaned. The operation is simple and the structure is reasonable.
