[0029] Compared with the method in which the entire filter screen is a filtering area except for the periphery, the filter screen provided in this embodiment, by providing an upwardly inclined guide area on the side of the filtering area that receives sewage, firstly, increases the depth of the filter screen and increases the volume of the filter screen for accommodating sewage; secondly, increases the flow rate of sewage to move the position where the dirt in the sewage is deposited on the filter screen to the side of the filtering area, thereby increasing the area of ​​the filtering area that performs the function of filtering sewage, and makes it difficult for sewage to overflow from the filter screen and pollute the ground.

[0030] The guide area 22 and the filter area 21 are located on both sides of the width direction of the filter, that is, the position where the filter receives sewage is located on one side of the width direction of the filter. The inclination angle range of the guide area 22 relative to the filter area 21 is greater than or equal to 40 degrees and less than or equal to 45 degrees. The inclination angle of the guide area 22 can be, for example, 40 degrees, 41 degrees, 42 degrees, 43 degrees, 44 degrees or 45 degrees. The width of the guide area is determined according to the filterable garbage and the frequency of filter cleaning. The aperture of the filter 2 is related to the size of the garbage to be filtered by the filter. In this embodiment, the aperture range of the filter is between 1.5 mm and 2.5 mm, for example, it can be 1.5 mm, 1.8 mm, 2 mm, 2.2 mm or 2.5 mm.

[0031] Except for the side receiving sewage, the outer periphery of the filter screen is provided with a peripheral wall 25, and the peripheral wall 25, the guide area 22 and the filter area 21 together form a receiving cavity with a gap. That is, the peripheral wall has a gap on one side of the guide area, and the sewage first enters the guide area and then enters the filter area through the gap. Due to the formation of the receiving cavity, when the amount of sewage entering the filter screen is relatively large, or when the sewage is blocked by dirt on the filter screen, the sewage is not easy to overflow from the filter screen.

[0032] A support plate 23 is provided on one side of the peripheral wall 25 of the filter screen 2 away from the guide area 22 . The support plate 23 extends along the width direction of the filter screen. A buckle 24 is provided on the support plate 23 .
