Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

Referring to fig. 1-3, the present utility model provides the following technical solutions: the utility model provides a just sink convenient to mud clearance, including cell body 1, the inboard bottom of cell body 1 is provided with mud collecting hopper 2, the inside of mud collecting hopper 2 is provided with suction pipe 3, mud collecting hopper 2 has a plurality ofly, the bottom of the pool of cell body 1 is fully spread to a plurality of mud collecting hoppers 2, the top bore of mud collecting hopper 2 is greater than its bottom bore, fixedly connected with communicating pipe 4 between two adjacent mud collecting hoppers 2, suction pipe 3 is linked together with communicating pipe 4, the one end of communicating pipe 4 runs through cell body 1 and is provided with electronic mud valve 6, one side bottom of cell body 1 is provided with mud pipe 5, the one end of mud pipe 5 is provided with mud pump 7, communicating pipe 4 is linked together with mud pipe 5.

In the specific embodiment of the utility model, the mud collecting hopper 2 is paved at the bottom of the inner side of the tank body 1, and the adjacent mud collecting hoppers 2 are closely attached. In the working process, the sinkable matters or floaters in the sewage can enter the sludge hopper 2 after being settled, and the top caliber of the sludge hopper 2 is larger than the bottom caliber of the sludge hopper 2, so that the side walls of the sludge hopper 2 are inclined planes, and the sinkable matters can move to the bottom of the sludge hopper 2 along the inclined planes after entering the sludge hopper 2.
