Abstract

The invention relates to a self-cleaning filter. The filter comprises an outer sleeve, a filter element and a water inlet, and further comprises a communication pipe, parallel pipes and flushing pipes. The water inlet is arranged on the communication pipe which is communicated with a plurality of the parallel pipes simultaneously. The plurality of the parallel pipes are parallel with the outer sleeve and distributed evenly around the outer sleeve along the circumference. A plurality of the flushing pipes communicating the plurality of the parallel pipes with the outer sleeve are arranged between each of the plurality of the parallel pipes and the outer sleeve, the flushing pipes are distributed evenly on the plurality of the parallel pipes along the length directions of the parallel pipes, and the plurality of the flushing pipes on each of the parallel pipes are mutually parallel and directly face the filter element. The filter element is flushed by the branch water current of the water inflow which is performed simultaneously from the plurality of the flushing pipes on the plurality of the parallel pipes. According to the self-cleaning filter, the self-cleaning effect can be achieved without external power sources, the structure is simple, the usage is convenient, the cost is low, and the filter is stable and reliable.

Description

technical field [0001] The invention relates to a filter, especially a self-cleaning filter. Background technique [0002] Self-cleaning 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. For working equipment, water enters the body of the self-cleaning filter from the water inlet. Due to the intelligent design, the system can automatically identify the degree of impurity deposition, and signal the sewage valve to automatically discharge sewage. Self-cleaning filter is currently widely used equipment in the water treatment industry. Its simple design and good performance enable the sewage to achieve the best filtering effect. The self-cleaning filter overcomes many disadvantages of traditional filtration products such as small dirt ...
