Multielement self-cleaning filter is a mechatronic equipment with the features of reasonable design, high efficiency of filtering, low running cost and successive filtering during the backwashing filtering. It could be extensively applied in the fields like metallurgy, chemical industry, power, injection water of the oil field and environmental water treatment.Work principleThe filtered liquid gets into the filter from the entrance and into the strainer from the lower plate. The liquid flows from the inner side of the strainer to the outer side and gets out from the filter through the exit of the filter cartridge. The impurity from the backwashing is drained from the drainage entrance.Process descriptionWhen the liquid flows from the inner side of the strainer to the outer side, the solid grain was held in the inner side of the strainer. With the increase of the pollutant, the pressure difference between the polluted side and the clean side is also growing. When the pressure difference reaches the set value, the automatic backwashing will start to work.Design feature of the multi- Core self- Cleaning filter1. The filter takes the internal mechanical structure of self-cleaning to realize the backwashing function in the true sense. It could clean the impurity on the strainer thoroughly. There is no dead angle for washing and no flux attenuation so that the filtering efficiency and the service life are assured.2. The filter takes the wedge strainer of 304, 316L stainless steel with high strength, precision and corrosion resistance. The filtering precision is 251im.3. The filter with few wearing parts, no consumable, low maintenance cost. The operation and management are simple.4. The control system of the filter is with sensitive response and precise operation. The backwashing pressure difference and the time could be adjusted flexibly according to the different water source and filtering precision.
