Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-3, a filter vat comprises a vat body 10, a filter element 20, a water inlet pipeline 30, and a water outlet pipeline 40; the filter core 20 is positioned in the barrel body 10, and the interior of the barrel body 10 is divided into a pre-filtering area 51 and a post-filtering area 52 by the filter core 20; the water inlet pipeline 30 is used for communicating with the pre-filtering area 51, and the water outlet pipeline 40 is used for communicating with the post-filtering area 52; a recoil pipeline 60 is also connected between the water outlet pipeline 40 and the water inlet pipeline 30; the barrel body 10 is also provided with a drain port 11 communicated with the filtering preposition area 51; the filter vat further comprises an emptying device 70 associated with the emptying port 11.

When the water purifier is used, water treated by the sewage treatment system can enter the pre-filtering area 51 of the barrel body 10 from the water inlet pipeline 30 and flow out from the water outlet pipeline 40 through the post-filtering area 52, and sand, mud and impurities in the water are blocked in the pre-filtering area 51 by the filter element 20, so that the sand, mud and impurities in the water can be effectively filtered, and the phenomenon that the sand, mud and impurities block pipelines is avoided when the water is used for cleaning a mesh belt.

The water inlet pipeline 30 includes a water inlet pipe 31 connected to the tub 10, and a water inlet valve 32 connected to the water inlet pipe 31. When in use, the water inlet valve 32 is opened, and water to be filtered can enter the barrel body 10 through the water inlet pipe 31. By adopting the structure of the water inlet pipeline 30, the cost can be conveniently reduced. In this embodiment, the water inlet valve 32 is a normally open valve.
