Automatic backwash filter

Product Overview
The automatic backwash filter is composed of a cylinder stainless steel filter, a sewage discharge part, a transmission device and an electrical control part. The operation and control of the filter can automatically clean, filter and discharge sewage. There is no flow during backwashing. The cleaning and filtration cycle can be adjusted. The default cleaning and filtration time is
. The water lost in cleaning and filtration only accounts for the filtered water volume
The filtration accuracy can reach micron. It can be installed vertically and horizontally. , can be used for water system filtration in various industries such as industry, agriculture, municipal power, electronics, medicine, food, printing and dyeing, construction, steel, metallurgy, papermaking, etc.
Working Principle
Water enters the filter from the water inlet. It first filters out larger particles of impurities through the coarse filter element assembly, and then reaches the fine filter. After filtering out the fine particles of impurities through the fine filter, the water is clean. Discharged from the water outlet. During the filtration process, the impurities in the inner layer of the fine filter gradually accumulate, forming a pressure difference on both sides of it. When this pressure difference reaches the preset value, the automatic cleaning process will begin. The drain valve will open, and the hydraulic motor chamber and hydraulic cylinder of the main pipe assembly will release the pressure and discharge the water. The pressure in the hydraulic motor chamber and sewage suction pipe will drop significantly due to the negative pressure. , the dirt on the inner wall of the fine filter is sucked through the suction nozzle, flows into the hydraulic motor chamber by the hydraulic motor, and is discharged by the drain valve, forming a sewage suction process. When water flows through the hydraulic motor, the sewage suction pipe is driven to rotate, and the hydraulic cylinder piston drives the sewage suction pipe to move axially. The sewage suction assembly completely cleans the inner surface of the entire filter screen through the combination of axial movement and rotational motion. The entire cleaning process will last tens of seconds. The drain valve closes at the end of cleaning, the increased water pressure causes the hydraulic cylinder piston to return to its original position, and the filter begins preparing for the next flushing cycle. During the cleaning process, the normal filtration work of the filter is uninterrupted.
