Automatic backwash filter ATZQ-120-200 is composed of a cylinder, stainless steel filter, blowdown part, transmission device and electrical control part. Automatic backwash filter ATZQ-120-200 can filter industrial wastewater, circulating water filtration, metallurgy industry continuous casting water, blast furnace water, etc.; Widely used in metallurgy, chemical industry, petroleum, paper, medicine, food, mining, electric power, urban water supply field.
The water enters through the inlet, passes through a coarse screen to filter out larger particles of impurities, and then reaches a fine screen. In the filtration process, the fine filter screen gradually accumulates the dirt and impurities in the water, forming the filter impurity layer. Because the impurity layer is accumulated on the inside of the fine filter screen, a pressure difference is formed on both sides of the fine filter screen.
When the pressure difference of automatic backwash filter ATZQ-120-200 reaches the preset value, the automatic cleaning process will begin. The water supply is not interrupted, the cleaning valve is opened, the water pressure in the cleaning chamber and the suction device decreases significantly. Through the pressure difference between the filter cylinder and the suction pipe, the suction pipe and the cleaning chamber produce a suction, forming a suction process. At the same time, the electric motor drives the suction pipe to spiral along the axial direction. The combination of axial and rotating motion of the suction device will clean the inner surface of the entire screen. The flushing process takes only a few seconds. The blowdown valve closes at the end of cleaning. The filter is ready for the next flush cycle.
1. Simple design structure.
2. Short reverse cleaning time, flow rate and pressure loss.
3. Intelligent control system (PLC, PAC) control, high degree of automation.
4. High precision filtration, stable water quality.
5. Can be applied to different raw water quality and water requirements.
6. Fewer wearing parts, no consumables, low operating costs, simple operation and management.
7. Automatic reverse cleaning without interruption.
