[0003] A self-priming sewage pump described in the prior art for facilitating the removal of blockage adopts a design of open impeller, including a water outlet short pipe, a water inlet flap valve and a pump body. The water outlet short pipe and the water inlet flap valve are both fixedly connected to the pump body. The axis of the water outlet short pipe is arranged to be perpendicular to the axis of the water inlet flap valve. A shaft is arranged in the pump body.

The shaft is installed in a bearing body and two ends of the shaft extend out of the bearing body respectively. An impeller is arranged on one end of the shaft inside the pump body. A left bearing and a right bearing are arranged in the bearing body, and the shaft extends through the left bearing and the right bearing respectively. A bearing cover is fixedly installed on an outer end of the bearing body.

After cleaning, the fixing shaft 401 is controlled to drive the dredging frame 5 to return and the slider 4 is controlled to continue to slide in the slideway 301 to retract the dredging frame 5 back into the mounting frame 1. Then, the dredging frame 5 rises to dredge and clean the floating impurities in the sewage due to the annular design of the slideway 301. The above operations are performed repeatedly. The slider 4 is arranged in the slideway 301. A side, away from the slideway 301, of the slider 4 is provided with the fixing shaft 401 configured to drive the dredging frame 5 to rotated to tilt or return. The dredging frame 5 is arranged on an end, away from the slider 4, of the fixing shaft 401, to dredge the floating impurities. A hole slot 6 and a cavity 7 are arranged at the top of the mounting frame 1, wherein a holding tank 701 is arranged on the inner wall of the mounting frame 1 to hold a filter frame 801 and to filter and collect the impurities that have sunk underwater. A baffle 601 is arranged in the hole slot 6, which can close the water delivery passage when the filter frame 801 is taken out for cleaning,

to prevent the impurities from being carried by the water flow to discharge. A pulling plate 8 and the filter frame 801 are arranged in the cavity 7. The filter frame 801 is configured to collect the impurities that have sunk underwater.

[0023] In the current prior art, the self-priming sewage pump may be used for discharging domestic water from a power plant. However, due to the large amount of impurities in the domestic wastewater, the anti-blocking structure inside the self-priming sewage pump cannot process the impurities after a long time of operation. Therefore, some impurities may jam into the sewage pump during discharging, causing damage to the components in the sewage pump.

As a result, the efficiency of the sewage pump is reduced, and the sewage pump may even fail to operate.

When in use, the water delivery pipe 101 first conveys the sewage into the mounting frame 1, and the slider 4 is controlled to slide in the slideway 301 at the same time.

When the slider 4 slides upward, it drives the dredging frame 5 to rise synchronously to dredge the impurities floating on the water surface. When the slider 4 slides into contact with the signal block 302, the slider 4 is controlled to stop and the fixing shaft 401 is controlled to rotate, so that the dredging frame 5 is tilted and the impurities contained in the dredging frame 5 is poured out , thereby cleaning the impurities.
