1. the invention can alternately convey water by arranging the upper and lower drainage cavities, does not need to close a sewage discharge pipeline when cleaning impurities, can realize non-stop operation and can greatly improve the sewage discharge efficiency.
2. According to the invention, through the arrangement of the counterweight roller and the connecting strip, when more impurities are accumulated at the upper side of the filter plate, the filter plate is gradually pushed forward, the counterweight roller is driven to rotate, and when the counterweight block on the counterweight roller rotates to the upper side, the inner container is driven to turn over around the axis of the inner container under the action of gravity, so that the two sewage discharge chambers are exchanged, and the sewage discharge chamber containing a large amount of impurities can be rotated to the lower side, so that the sewage can be discharged efficiently.
3. According to the invention, the two filter plates can be connected together by arranging the connecting strip, so that the two filter plates are linked, and in the process that the filter plate positioned on the upper side is pushed forwards, the filter plate positioned on the lower side can be pulled backwards, and impurities and the like are pushed backwards and discharged from the sewage discharge outlet, so that the impurities are automatically cleaned.
4. According to the invention, the water filtering plate is arranged, so that the dry-wet separation of impurities can be realized, and the later recovery treatment of the impurities is facilitated.
5. According to the invention, the return pipe is arranged, and as the fluid in the drain pipe rapidly flows, the pressure in the drain pipe is smaller than that of the return pipe according to the Bernoulli principle, and the drain pipe can suck the sewage in the return pipe and take away the sewage under the action of pressure difference, so that the subsequent sewage treatment procedures are reduced, and meanwhile, the storage space of the storage box can be increased.
