1. Description
The Automatic cleaning filter is a kind of precision equipment that uses the filter screen to directly intercept the impurities in the water, remove the suspended solids and particles in the water, reduce the turbidity, purify the water quality and reduce the generation of system dirt, bacteria, algae and rust, so as to purify the water quality and protect the normal operation of other equipment in the system. The water enters the self-cleaning filter body from the water inlet. Due to the intelligent (PLC, PAC) design, the system can automatically identify the deposition degree of impurities, Signal the blowdown valve for automatic blowdown.
2. Working Principle
When the pressure difference reaches the preset value, or when the preset time is due, the filter will start a self cleaning prcess, during which, the brush in the filter screen will rotate, brushing down the impurities caught by the filter screen, and then the impurities will be discharged from the drain valve.

4. Application
Steel: for the raw material field, sintering pellet plant water treatment filter, blast furnace, rolling mill, continuous casting machine and other systems cooling water filtration, high pressure water phosphorus removal system impurity filtration.
Car: Painting production lines, in the automotive, tractors, motorcycles, engine manufacturing water, processing systems are widely used.
Power plant: for the power plant boiler high purity water preparation of the precision pre-treatment part of the generator cooling water, sealed with water filtration, the Department of 13-4 water when the amount of water can be used as a side filter.
Petrochemical: in the circulating water to do next filter, single or multi-model parallel processing, instead of filter media filter to reduce the filter load filter, to avoid a lot of washing water consumption, cost savings.
Agricultural garden and paper mills: in the nozzle, nozzle system, should be reduced due to impurities caused by equipment clogging, wear, so need to choose high-precision, high automation filter products machinery, food or other: the system automatically, Used to prevent the cooling water system is blocked.
Mine: filter underground spray water to ensure that the system is working properly.
Water supply and sewage treatment: for pre-treatment system, improve system efficiency.
