Description

Technical Field

[0001] The utility model relates to a filter cloth rotary disk filtering device, in particular to a double-sided cleaning filter cloth rotary disk filtering device. Background Art

[0002] The filter cloth turntable filter tank is an external inlet and internal flow type. The filter medium is the filter cloth, which is made of a new type of nano material, has the characteristics of hydrophobicity and oleophobicity, and impurities are not easy to adhere. During the filtration period, the filter turntable is in a static state, which is conducive to the sedimentation of sludge at the bottom of the pool. During the filtration process, a sludge layer gradually forms on the surface of the filter cloth. With the accumulation of sludge on the filter cloth, the filtration resistance of the filter cloth increases, and the water level of the filter tank gradually rises. The liquid level changes in the pool are monitored by a liquid level meter. When the liquid level in the pool reaches the cleaning set value (high water level), the PLC can start the backwash pump and start the cleaning process. During the cleaning process, the filter tank can filter continuously.
