Steam-water backwashing device for quartz sand filter

Abstract

This utility model discloses a backwashing device for a quartz sand filter. A PLC controller is connected to the source water pump, the backwash pump, and the pipeline control terminal. The PLC controller can control the source water pump and the backwash pump, and can also communicate with the pipeline control terminal. The quartz sand filter includes a filter pipeline, a backwash pipeline, and an outlet pipeline. The filter pipeline is equipped with a first and a second electric butterfly valve, the backwash pipeline is equipped with a third and a fourth electric butterfly valve, and the outlet pipeline is equipped with a fifth electric butterfly valve. This application integrates components such as the source water pump, the backwash pump, the electric butterfly valves, and the pressure relief solenoid valve into a unified control system to achieve fully automated and precise control of the backwashing process. Simultaneously, through optimized pipeline layout and safety protection design, it improves backwashing efficiency, reduces energy consumption, and ensures safe equipment operation.
