Daxing automatic backwash filter

.
Product Overview:
The automatic backwash filter is composed of a cylinder, a stainless steel filter screen, 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

.%
of the filtered water volume. The filtration accuracy can reach
Micrometer can be installed vertically or horizontally, and 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 screen, through which fine particles are filtered out. After removing the impurities from the particles, the clean water is 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 start: the drain valve opens, the hydraulic motor chamber and hydraulic cylinder of the main pipe assembly release the pressure and discharge the water. The pressure in the hydraulic motor chamber and sewage suction pipe drops significantly, due to the negative pressure Function, 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.
