Description

Filter screen piece and drainer down Technical Field The utility model relates to the technical field of drainage, in particular to a drainage filter screen piece and a drainage device. Background The sewage filter screen is a device for filtering dirt and garbage in a drainage system, water flows from all directions of the sewage filter screen, and the filtering effect is realized through filter holes on the sewage filter screen. The existing sewage filter screen structure is provided with a plane filter screen, is of a simple net piece structure, has no dirt storage space, and needs to be cleaned frequently in use so as to avoid the problems of blockage or dirt and garbage being washed off. The filter basket is arranged in the conventional water-supply filter screen structure, and the capacity of the filter basket is increased through the deep groove design, so that dirt and garbage can be stored. In use, water flows from all directions of the lower filter basket, and is filtered and drained mainly through the bottom of the tank, the drainage flow is basically fixed, and the problem of water accumulation is easy to occur in use. The dirt and garbage stored in the filter basket is mainly accumulated at the bottom of the tank under the drive of water flow, and once the dirt and garbage block the filter holes at the bottom of the tank, the drainage speed is quickly slowed down, and even the filter holes are completely blocked so that drainage cannot be performed. Therefore, although the filter basket has a storage space for storing dirt and garbage, the effect of garbage storage and normal drainage is difficult to be achieved in actual use. In addition, the filter basket structure also has the problem that the cleaning difficulty of the internal structure is high. In view of the above, the present invention has been made in an intensive study on the above problems, and provides a sewage filter member and a sewage device. Disclosure of utility model The utility model aims to provide a sewer screen member and a sewer device, which have the functions of garbage storage and normal drainage and have the effect of increasing flow rate along with the increase of water level. In order to achieve the above object, the solution of the present utility model is: a sewage filter screen member having a filter screen body with an annular support portion and a raised portion formed at a central position of the annular support portion and protruding upward, the raised portion having a main drain opening with a downward opening; The filter screen comprises a filter screen body, wherein the filter screen body is provided with a plurality of first filter holes, a plurality of second filter holes are formed in the bulge part, the first filter holes are distributed around a central line, the plurality of second filter holes are distributed around the central line on the annular support part, the lowest positions of the first filter holes are higher than the highest positions of the second filter holes, and an annular garbage storage groove is formed between the lowest positions of the corresponding first filter holes and the highest positions of the second filter holes on the filter screen body. Further, the garbage storage tank is of an arc-shaped tank structure with an upward opening.
