Self-cleaning filter machine

Abstract

The invention discloses a self-cleaning filter machine, and aims to provide a self-cleaning filter machine which does not require replacing an internal filter core. The key point of the technical scheme is that the self-cleaning filter machine comprises a tank body; one side of the top part of the tank body is provided with an inlet pipe connected with the tank body, one side of the bottom part thereof is provided with an outlet pipe; a filter device is arranged in the tank body, and a scraping device is arranged in the tank body at outside of the filter device; the scraping device comprises abottom plate located at the lower part of the outlet pipe of the bottom part of the tank body, a leak opening in the middle of the bottom plate, a blow-off pipe located at the lower part of the leakopening and connected with the tank body, a rotary shaft penetrated to the tank body until the leak opening, a driving device located on the tank body for driving the rotary shaft to rotate, a cross rod perpendicularly connected with the rotary shaft, and a wiping block located on the cross rod for leaning to the surface of the filter device.

Description

technical field [0001] The invention relates to the field of filter equipment, in particular to a 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 of auto...

Problems solved by technology

[0004] Although this automatic cleaning filter uses a continuously rotating filter drum to filter the impurities in the liquid containing solid phase, the nozzles above the filter drum are used to wash and clean, and the impurities are separated and collected. Energy and no consumption, but it often has some impurities stuck inside during use, so it is impossible to completely clear the impurities inside
