一种给排水污水预处理装置
By introducing a drive structure and a moving motor into the water supply and drainage sewage pretreatment device, the motor driven by the drive structure drives the screw and the limiting column, enabling the interchange of filter plates without stopping drainage and the movement of the motor. The motor drives the connecting block and the supporting block, thereby enabling the interchange of the filter plates. This solves the problem of poor practicality caused by filter plate clogging and improves the practicality and treatment efficiency of the device.

AI Technical Summary
The filter plates of existing water supply and drainage sewage pretreatment devices are prone to clogging after prolonged use, which requires a long period of time to stop drainage for cleaning or replacement, affecting their practicality.
A drive structure is used to move the secondary treatment frame. By interchangeing the secondary treatment frame with the main treatment frame, the filter plates can be replaced or cleaned without stopping the flow. The motor drives the screw and limit post to move the connecting block and support block, thereby realizing the interchange of the filter plates. The water flow channel is controlled by the sealing ring and control valve.
This allows for the cleaning and replacement of filter plates without interrupting water flow, improving the practicality of the device, reducing filter plate clogging, and ensuring the continuity and efficiency of wastewater treatment.
