Description

Technical Field

[0001] The utility model relates to the technical field of cleaning structures of filter washers, in particular to a cleaning structure of a backwash filter. Background Art

[0002] Filter backwashing is a precision equipment that uses a filter to directly intercept impurities in the water, remove suspended solids and particulate matter in the water, reduce turbidity, purify water quality, reduce system dirt, algae, rust, etc., to purify water quality and protect the normal operation of other equipment in the system. Water enters the self-cleaning filter body from the water inlet. Due to its intelligent design, the system can automatically identify the degree of impurity deposition and give a signal to the drain valve to automatically drain the sewage.

[0003] After the current filter washer has been used for a long time, coarse particles, sand, rust, etc. are easily attached to the filter element of the pre-filter, resulting in a decrease in the amount of water passing through. In severe cases, the filter may be blocked. The current common method for cleaning is manual disassembly and cleaning, which requires taking out the internal filter element and manually brushing its surface. However, this cleaning method is inconvenient to disassemble, which wastes time and manpower. The sand attached to the surface or gap of the filter element is small in volume and has strong viscosity. Simple manual flushing can only remove impurities with larger volume on the surface of the filter element, but the cleaning effect on smaller sand is poor, and the filter element cannot be cleaned more thoroughly.
