The specific embodiment

Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.

In the present embodiment, the floating bed filter comprises housing 1; Distribution device 2; Cleaning device 3; Meticulous microfilter device 4.The housing 1 of telling comprises slurries cell body 5, cell body support 6, crane span structure 7, guardrail 8, overflow passage 9, discharge pipelines 10.Distribution device 2 comprises 12 of charge pipes 11, flocculant pipeline 18, degree of depth material distribution cartridge; Cleaning device 3 comprises flushing line 13 and spray equipment 14.Meticulous microfilter device 4 comprises center clarifier 15, the floating net 17 of annular.Cell body 5 is fixed on the cell body support 6, and the first half of cell body 5 is cylinder, and Lower Half is cone.The bottom that cell body 5 tops are equipped with crane span structure 7, guardrail 8 and cell body 5 is equipped with discharge duct 10, and the top center of cell body 5 is hung with degree of depth material distribution cartridge 12.Charge pipe 11, flocculant pipe 18 are positioned at the upper end of cell body 5, charge pipe 11 is linked degree of depth material distribution cartridge interior 12, flocculant pipe 18 is connected in degree of depth material distribution cartridge 12 and the charge pipe 11, and the center of degree of depth material distribution cartridge 12 is fixed with center clarifier 15, and the top of cell body 5 inner side edges is equipped with overflow pipe 9.Under overflow pipe 9, the floating net 17 of annular is installed between deep material distribution cartridge 12 and the cell body 5, the floating net 17 of annular is to have cleaning device 3, and cleaning device 3 comprises flushing line 13 and spray equipment 14, and spray equipment 14 is installed on the flushing line 13.

Distribution device 2 adds degree of depth material distribution cartridge 12 with original slurry by charge pipe 11, and flocculant pipe 18 is simultaneously to charge pipe 11 and the 12 interior interpolations of degree of depth distribution barrel, so that flocculant can fully mix with slurries and flocculate.Degree of depth material distribution cartridge 12 is peeled off fed slurry and supernatant liquid, and material is directly added cell body 5 middle and lower parts, reserves enough rising spaces.
