Description

Technical Field

[0001] The invention relates to the technical field of equipment self-cleaning filtration, in particular to a double self-cleaning filter. Background Art

[0002] Automatic cleaning filter is a kind of precision equipment that uses filter screen to directly intercept impurities in water, remove suspended matter and particulate matter in water, reduce turbidity, purify water quality, and reduce system dirt, bacteria, algae, rust, etc. It is also called fully automatic self-cleaning filter, backwash filter, automatic sewage filter. In the work of some pneumatic machinery and hydraulic machinery, due to long-term conveying fluid medium, impurities and dirt are easily deposited in pipelines and valves, such as suspended matter, particulate matter, bacteria, algae, rust, etc. These impurities and dirt are deposited in the pipelines of the equipment, which is easy to damage the pipelines of the equipment and pollute the quality of the conveying fluid. The traditional way is to install filters on pneumatic machinery and hydraulic machinery, so as to purify the conveying fluid. However, the filtering effect of this single-station cleaner in actual filtering work is not good, because it only performs one filtration, and impurities in the fluid medium are still difficult to be cleaned up, and impurities and dirt are still easy to accumulate in key areas such as pipelines and valves, and the cleaning efficiency is low; However, although the filter can filter out impurities and dirt in the equipment, these impurities are easily deposited in the filter during long-term filtering work, and the filter is difficult to self-clean. Therefore, the impurities and dirt in the filter are easily deposited in the filter and easily flow back into the equipment to cause secondary pollution. In addition, the filter needs to be cleaned regularly, and the work intensity is high. When cleaning the filter, the equipment cannot be filtered and the equipment needs to be shut down, which reduces the filtering efficiency of the equipment and affects the normal production of the equipment.
