Description

technical field [0001] The invention relates to the field of filter equipment, in particular to a scraper self-cleaning filter. Background technique [0002] Self-cleaning filter is a kind of filter that directly intercepts impurities in liquid containing solid phase, removes suspended solids and particulate matter in liquid containing solid phase, reduces turbidity, purifies liquid quality containing solid phase, and reduces system dirt, bacteria and algae , rust, etc., to purify the liquid containing the solid phase and to protect the precision equipment of other equipment in the system. The liquid containing the solid phase enters the body of the self-cleaning filter from the liquid port containing the solid phase. PAC) design, the system can automatically identify the degree of impurity deposition, and send a signal to the sewage valve to automatically discharge the sewage. [0003] At present, the Chinese patent whose publication number is CN102716611A discloses a kind...
