[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model solves the problem of time wasting when cleaning by setting a filtering structure. After the sewage enters the sewage tank, it will flow into the clean water tank. In the process of the sewage flowing into the clean water tank, the filtering structure in the placement groove installed on the partition can filter the suspended particles in the sewage. The water flows into the filter plate frame from the upper end. When it flows to the first filter plate, the suspended particles in the sewage are filtered by the first filter plate, and the clean water flows into the clean water tank. When the sludge fills the filtering structure, the first valve is opened to discharge the sludge in the filtering structure from the sewage outlet to the sludge pipe from the connecting port on the side of the clean water tank. The sludge pipe is transported to the first connecting pipe, thereby effectively solving the problem of time wasting when cleaning after using for a period of time.

[0014] When it is necessary to meet different filtering standards, the sewage pipe is closed, and the staff pulls the handle to pull the filter structure out of the placement tank, replaces the first filter plate with different filtering effects, and puts the filter structure back into the placement tank after replacement, ensuring that the sewage outlet is aligned with the connection port and the blocks on both sides are in the slots. The replacement is completed, thus solving the problem of inconvenient replacement of filter plates when different usage needs are met.

[0015] 2. The utility model solves the problem that the sludge after filtration needs to be precipitated and separated by setting a filter press box. The filter press box can collect the sludge transported by the first connecting pipe, control the first hydraulic cylinder to extend the first telescopic rod, and the second filter plate installed at one end of the first telescopic rod can squeeze the sludge collected by the filter press box to effectively separate the water contained in the sludge. The separated clean water will be transported to the clean water pipeline by the second connecting pipe. Open the second valve and continue to extend the first telescopic rod. The separated sludge will be discharged from the sludge discharge pipe to the subsequent process, thereby realizing the effective separation of sludge and water.

[0016] The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art. BRIEF DESCRIPTION OF THE DRAWINGS
