Detailed Description

The invention will be further described with reference to examples of embodiments shown in the drawings.

As shown in fig. 1, the basket filter includes a cylinder 1 having an inlet 11 and an outlet 12 on a circumferential surface thereof, an inlet flange 13 and an outlet flange 14 connected to the inlet 11 and the outlet 12, respectively, a drain flange 16 connected to an upper port 15 of the cylinder 1 serving as a drain outlet, a sealing head 17 having a sealing cover disposed on a lower port of the cylinder 1, a flange cover 18 connected to the drain flange 16, a drain valve 19 disposed on the flange cover 18, a retainer 2 fixedly mounted in the cylinder 1, and a filter assembly 3 disposed on the retainer 2 and separating the inlet 11 from the outlet 12. A gasket 4 is arranged between the sewage flange pipe 16 and the flange cover 18. Retaining ring 2 is cyclic annular, and retaining ring 2 sets up with the axis of barrel 1 slope mutually, and the axis of retaining ring 2 is 30~60 with the contained angle of the axis of barrel 1.

The filter component 3 comprises a filter cylinder 5 and a filter screen 6 filled in the filter cylinder 5, wherein the outer ring of an upper port 15 of the filter cylinder 5 is provided with a flange 7, and the flange 7 is arranged on the retainer ring 2.
