Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in figure 1, the sewage filtering device provided by the utility model comprises a box body 1, a water inlet pipe 2 is welded above the box body 1, the water inlet pipe 2 is communicated with the box body 1, and sewage is conveyed into the box body 1 through the water inlet pipe 2.

Top welding baffle 3 in box 2, baffle 3 will box 2 separates for last cavity 4 and lower cavity 5 go up welding filter screen 4.1 in the cavity 4, filter screen 4.1 sets up the below of inlet tube 2, sewage gets into from the inlet tube 2, then falls on filter screen 4.1, filters through filter screen 4.1, filters great impurity and rubbish in the sewage.

The partition plate 3 is obliquely arranged, a through hole is formed in the lower side of the side face above the partition plate 3, a water delivery pipe 8 is welded below the through hole, the water delivery pipe 8 is communicated with the upper cavity 4, and filtered sewage slides downwards along the oblique direction of the partition plate 3 and then enters the water delivery pipe 8.
