The filter is an indispensable device on the conveying medium pipe. It is usually installed in the inlet device of pressure reducing valves, pressure reducing valves, fixed water level valves and other equipment for square filters. The filter consists of a cylinder, a stainless steel filter, a drain section, a transmission and an electrical control section. After the water to be treated passes through the filter cartridge of the filter, the impurities are clogged. When cleaning is required, the detachable filter cartridge can be removed and reloaded after handling, making maintenance very convenient.

Filter


When the filter is in operation, the water to be filtered enters through the nozzle, flows through the filter, enters the process required by the user through the outlet, and the particulate impurities in the water are trapped in the filter. With this continuous cycle, more and more particles are trapped, the filtration speed is slower and slower, the imported sewage continues to enter, and the filter holes become smaller and smaller, thereby generating pressure between the inlet and the outlet. Poor, when the difference reaches the set value, the differential pressure transmitter transmits an electrical signal to the controller, and the control system starts to drive the motor drive shaft to rotate through the transmission component, the sewage outlet opens, and is discharged by the sewage outlet. After the cleaning is completed, the differential pressure is reduced to the minimum value, the system returns to the initial filtering state, and the system operates normally. The filter consists of a housing, a multi-element filter, a backwash mechanism and a differential pressure controller. The diaphragm in the housing divides the inner chamber into an upper chamber and a lower chamber, and the upper chamber is provided with a plurality of filter elements, so that the filtering space is sufficient, the volume of the filter is significantly reduced, and the back chamber is installed with backwashing. Suction cup. During operation, the turbid liquid enters the lower chamber of the filter through the inlet and enters the interior of the filter element through the separation aperture. Impurities larger than the filter gap are captured, the cleaning liquid passes through the slit to the upper chamber, and finally is sent out from the outlet. The filter uses a high-strength wedge filter to automatically clean the filter element through differential pressure control and timing control. When the impurities in the filter accumulate on the surface of the filter element and the pressure difference between the inlet and the outlet increases to a set value, or the timer reaches a preset time, the electric control box sends a signal to drive the backwashing mechanism. The discharge valve opens when the backwash suction port is directly opposite the filter inlet. At this time, the system is emptied, and a negative pressure zone is formed inside the suction cup and the filter element, which is lower than the water pressure outside the filter, forcing part of the circulating water to flow out from the outside. filter. The inside of the filter element flows into the inside of the filter element, and foreign matter particles adsorbed on the inner wall of the filter element flow into the tray with water and are discharged from the discharge valve. A specially designed filter produces a jetting effect inside the filter element, and any impurities are washed away from the smooth inner wall. When the pressure difference between the inlet and outlet of the filter returns to normal or the timer set time ends, the material continues to flow throughout the process, and the backwash consumes less water, enabling continuous and automated production. Filters are widely used in metallurgy, chemical, petroleum, paper, pharmaceutical, food, mining, electricity, urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration, metallurgical industry continuous casting water system, blast furnace water system, hot rolling high pressure water descaling system. It is an advanced, efficient and easy to operate fully automatic filter unit.
