Filter is one of the necessary means of conveying medium pipe, usually installed in the pressure reducing valve, pressure relief valve, the constant water level valve, the other equipment of the import side of the filter equipment. When the filter cartridge is provided with a filter cartridge, the impurity is blocked, and when the filter is needed to be cleaned, the filter cartridge can be removed, and then the filter cartridge can be disassembled. Therefore, the use of maintenance is very convenient.

The filter is composed of a simplified, stainless steel filter screen, a sewage part, a transmission device and an electric control part. When the filter works, the filtered water flows through the filter screen, and the pipeline is circulated through the outlet of the pipeline, and the particles in the water are trapped inside the filter screen. This constant cycle, more and more particles trapped down, filtering speed more slowly, and imported into the sewage is still Everfount, filter holes will become increasingly smaller, resulting in pressure difference between inlet and outlet, when large difference reaches the set value, the differential pressure transmitter electrical signals will be transmitted to the controller, control system start the drive motor to rotate through the transmission shaft assembly drives the sewage outfall, at the same time open, discharged from the sewage outfall, when the filter cleaning is finished, the pressure dropped to the minimum value, the system returns to the initial filter, the normal operation of the system.

The filter is composed of a casing, a multiple filter element, an anti flushing mechanism, and a differential pressure controller. The diaphragm casing of the inner cavity is divided into two cavity, the upper cavity is provided with a plurality of filter elements, so as to make full use of the space filtering, significantly reducing the size of the filter, the inferior vena cava is installed in the backwash sucker. When working, the emulsion entrance into the filter chamber, and the inner baffle hole into the filter. Than the filter element gap impurities were trapped, the net liquid through the gap to reach the upper chamber, and finally sent out from the exit.

Filter with high strength of the wedge filter, through the pressure control, timing control automatic cleaning filter. When the filter impurities accumulated in the filter surface caused by the import and export pressure is increased to the set value, or when the timer reaches the preset time, the electric control box sends out the signal, drives the back flushing mechanism. When the backwash suction port and the filter is imported when the sewage valve is opened, the pressure relief drainage system, the sucker and the inside of the filter is a relative pressure below the negative pressure zone of the filter lateral pressure, forcing some clean circulating water from the outside into the inside of the filter cartridge, adsorption of impurities particles in the filter on the inner wall with the water flow into the Rang disc and is discharged from the drain valve. The special design of the filter inside the filter to produce a spray effect, any impurities will be washed away from the smooth wall. When the filter pressure difference is normal or timer setting time is over, the whole process, material flow, backwash water consumption, realizes continuous and automatic production.
