Description

technical field

[0001] The invention relates to the technical field of pipeline filtering, in particular to a pipeline filtering device with self-cleaning function. Background technique

[0002] Pipeline filtration is widely used in municipal, household, industrial and many other industries, and is mainly used to filter impurities in pipelines to prevent troubles for subsequent use or blockage of equipment. Especially in mountainous and rural areas, most of the drinking water is from nearby mountain springs. In the absence of standardized treatment, there will inevitably be some large impurities in the water; in addition, long-term intermittent use of water pipes is also unavoidable. The algal plants that produce moss occasionally bring out some large impurities during use, so the water needs to be filtered.

[0003] At present, there are some filters installed at the water outlet of the faucet, but all of them need to be disassembled and cleaned manually. When cleaning, th...
