The CKD filter is a fully automatic filter device that is safe and easy to operate. High-strength wedge-shaped filter net is used to automatically clean the filter element through pressure difference control and timing control. When the impurity in the filter is accumulated on the surface of the filter element, causing the inlet and outlet pressure difference to increase to the set value, or when the timer reaches the preset time, the electric control box sends out a signal to drive the backwashing mechanism. When the backwash is directly facing the inlet of the filter element, the drain valve is opened, and the system releases pressure and drains water. A negative pressure zone with a relative pressure lower than the water pressure outside the filter element appears on the inside of the suction cup and the filter element, forcing part of the net circulating water to flow into the filter element from the outside of the filter element. On the inner side, the impurity particles adsorbed on the inner wall of the filter element flow into the pan with the water and are discharged from the drain valve. The specially designed filter makes the inside of the filter produce a spray effect, and any impurities will be 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 setting time ends, during the whole process, the material will not flow continuously, and the water consumption for backwashing is small, realizing continuous and automatic production. Widely used in metallurgy, chemical industry, petroleum, paper mining, electric power, urban water supply fields. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system, blast furnace water system in metallurgical industry, high pressure water descaling system for hot rolling.
