1. Water filter functions and uses Water filters are widely used in metallurgy, chemical industry, petroleum, papermaking, medicine, food, mining, electric power, and urban water supply. Such as industrial wastewater, circulating water filtration, emulsion regeneration, waste oil filtration treatment, continuous casting water system, blast furnace water system in the metallurgical industry, and high-pressure water descaling system for hot rolling. It is an advanced, efficient and easy-to-operate fully automatic filtration device. 2. Water filter equipment structure and working principle The water filter consists of a shell, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve and a differential pressure controller. The diaphragm in the housing divides the inner cavity into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which makes full use of the filter space and significantly reduces the size of the filter. A backwash is installed in the lower chamber. Suction cups. During operation, the turbid liquid enters the lower chamber of the filter through the inlet, and then enters the inner chamber of the filter element through the partition hole. Impurities that are larger than the gap in the filter core are intercepted, and the clean liquid passes through the gap to the upper chamber, and is finally sent out from the outlet. The filter element of this filter uses a high-strength wedge-shaped filter screen, and the filter element is automatically cleaned through pressure difference control and timing control. When impurities in the filter accumulate 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 recoil mechanism. When the backwash suction cup mouth is directly opposite the filter element inlet, the drain valve is opened. At this time, the system is depressurized and drained. A negative pressure zone appears inside the suction cup and the filter element with a relative pressure lower than the water pressure outside the filter element, forcing part of the net circulating water to flow from the outside of the filter element. It flows into the inside of the filter element, and the impurity particles adsorbed on the inner wall of the filter element enter the suction cup with the water flow and are discharged from the drain valve. The specially designed mesh creates a spray effect inside the filter element, and any impurities will be washed away from the smooth inner wall. When the pressure difference between the filter inlet and outlet returns to normal or the timer setting time expires, the motor stops running and the electric drain valve closes. During the entire process, materials flow continuously and backwashing consumes less water, achieving continuous and automated production.
