■ Product Overview
Full automatic high efficiency backwash filter is one of the products developed by the company on the basis of introducing foreign automatic backwash filter (Patent No.: l20142138615.6). It has the characteristics of reasonable structure, reliable performance, good self-cleaning effect, convenient maintenance and use. It is a renewal product of traditional (particle filter material as medium) filtration, widely used in metallurgy, petrochemical industry, coal processing, papermaking, electric power and other industries.

■工作原理
工作时,液体从入口进入过滤器,其中一部分液体从中间的分流管中进入过滤器上部,液体同时从滤元上下端口同时进入,通过滤芯后在出口处汇集流出,颗粒杂质被拦截、积累形成滤饼,使过滤器进出口产生压差逐渐变大,表明滤饼达到一定厚度。当进出口压差达到设定压差值或设定时间,自清洗程序启动,电机驱动内部排污吸嘴对准滤筒并开启排污阀,通过水流的逆向流动冲刷滤筒内表面将杂质排出,然后关闭排污阀,排污吸嘴对准下一只滤筒,进行反清洗。所有滤筒逐个清洗后,整个反冲洗过程完成。

■ working principle
During operation, the liquid enters the filter from the inlet, and part of the liquid enters the upper part of the filter from the middle shunt pipe. At the same time, the liquid enters from the upper and lower ports of the filter element at the same time. After passing the filter element, it collects and flows out at the outlet. The particle impurities are intercepted and accumulated to form the filter cake, which gradually increases the pressure difference between the inlet and outlet of the filter, indicating that the filter cake reaches a certain thickness. When the pressure difference between the inlet and outlet reaches the set pressure difference or the set time, the self-cleaning program is started, the motor drives the internal blowdown suction nozzle to align with the filter cartridge and opens the blowdown valve, then the impurities are discharged by flushing the inner surface of the filter cartridge through the reverse flow of water, then the blowdown valve is closed, and the blowdown suction nozzle is aligned with the next filter cartridge for back cleaning. After all filter cartridges are cleaned one by one, the whole backwashing process is completed.
