Abstract

A hydraulically driven and self-cleaning backwash water filter disclosed by the present invention includes a cylinder, a storage chamber is arranged inside the cylinder, and a first-stage filter chamber is arranged on the upper side of the storage chamber. There is a filter box, and the present invention achieves the purpose of backwashing by controlling the opening and closing of the valve, and for the traditional circuit control system, it is judged whether backwashing is needed by the pressure difference inside and outside, and the present invention realizes backwashing through hydraulic drive and lifting of the floating plate. To realize backwashing, no complex control circuit is needed, and the device can be operated only by the flow of sewage, and the invention has simple structure, convenient maintenance, no need for monitoring, and fully automatic backwashing operation.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a hydraulically driven and self-cleaning backwash water filter. Background technique [0002] Backwash filter is a kind of filter that directly intercepts impurities in water, removes suspended solids and particulate matter in water, reduces turbidity, purifies water quality, reduces system dirt, bacteria and algae, rust, etc., to purify water quality and protect other equipment in the system Precision equipment that works properly. [0003] However, for the existing backwash water filter, it uses the control circuit to sense the pressure difference inside and outside to determine whether to perform backwash, which will lead to a complicated internal structure and difficult maintenance. If there is a problem with the internal parts, it needs to be repaired Disassemble it for inspection, or even replace it directly. [0004] The present invention illustrates a device capable of s...
