Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0026] The invention provides a backwashing device for a rotary disc filter, the embodiment of which is as follows Figure 1 to Figure 5 Shown, comprise filter tank 10, filter disc 20, drive motor 30, support frame 40 and recoil pump 50; Filter tank 10 is provided with a plurality of filter discs 20; Multiple filter discs 20 are coaxially located at drive motor 30 On the rotating shaft; the drive motor 30 is used to drive a plurality of filter discs 20 to rotate synchronously; the support frame 40 is arranged on the top of the filter tank 10, the support frame 40 is provided with a water guide pipe 41, and the water guide pipe 41 is connected to the recoil pump 50. A plurality of recoil nozzles 42 are arranged on the water guide pipe 41, and the plurality of water guide pipes ...

The invention discloses a backwashing device of a rotary disc filter. The backwashing device comprises a filter tank, filter discs, a driving motor, a support frame and a backwashing pump; a plurality of filter discs are arranged in the filter tank; the driving motor is used for driving the plurality of filter discs to rotate synchronously; water guide pipes are arranged on the support frame, and a plurality of backwashing nozzles of the plurality of water guide pipes are respectively opposite to the same sides of the plurality of filter discs; a plurality of anti-diffusion nozzles are also arranged on the water guide pipes between the adjacent filter discs, and the plurality of anti-diffusion nozzles and the plurality of backwashing nozzles are respectively arranged on two opposite sides of the water guide pipes and spray downwards in an inclined manner; and the backwashing pump is used for controlling the plurality of backwashing nozzles and the plurality of anti-diffusion nozzles to spray water. When sludge is flushed by the backwashing nozzles to fall off, the anti-diffusion nozzles can spray the sludge downwards, sinking of the sludge is accelerated, re-adhesion of the sludge on the filter discs is reduced, and the problem that an existing backwashing device of the rotary disc filter is high in repeated adhesion rate is practically solved.
Description
technical field [0001] The invention relates to the technical field of filter washing, in particular to a backwashing device for a rotary disc filter. Background technique [0002] In the existing rotary disc filter backwashing device, the backwashing pump is used to supply water to the backwashing nozzle, so as to generate high-pressure water flow to spray the filter disc, and the sludge on the filter disc will fall, but due to the sludge There are many kinds of floating objects with light weight in the water, and the sinking speed of the floating objects is slow, so these floating objects will easily re-adhere to the filter disc during the process of floating on the water, resulting in repeated sticking of the rotary disc filter backwashing device. Attachment rate is too high, therefore be badly in need of a kind of technical scheme that can solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a rotary disc filter bac...
