The automatic filter is a new structure product of copper sintering muffler

The structure of the automatic filter is novel, and the automatic filter does not need to be equipped with a backwash pump. By adopting simple and unique methods, all kinds of problems existing in manual operation in filtration and backwashing have been successfully solved, and the advantages of full automation have been brought into full play. It has effectively solved many problems that traditional filtering system is difficult to solve, and has been unanimously praised by users.

Since the filter is not equipped with a backwash pump, because the backwash water volume is about 3 times of the influent water, in order to consider that the composite muffler in the equipment has enough backwash water, the condition is that there is a clear water area in the equipment. The whole equipment is divided into two units to work at the same time. When one unit is backwashed, the other unit filters as usual to supplement the water body of the backwashing unit, plus the clear water area Because the unit area of a unit is about half of the area of the whole equipment vent muffler, its backwash water is also treated as a downward floating proportion.

Submit.

Therefore, this structure meets the requirements of the operating filter. PC program control program is used to control the whole process of the device to realize the work and operation of the automatic device. Instrument, contact and other control systems, start work, automatically open the inlet valve, close the drain valve.

According to the program compiled by PC, the automatic control part of each unit starts to work at the same time. When the muffler of centrifugal fan of a unit works to the time specified by PC (1-24 hours adjustable), the inlet valve will close automatically and the outlet valve will open automatically. When the backwashing is in operation, the backwashing time can be adjusted for 4-6 minutes, now it is 4 minutes. When the backwashing time is over, the inlet valve will be opened automatically, and the exhaust valve will be closed to return to the normal operation procedure. Other units are the same as above and continue to work normally.
