Description

Technical Field

[0001] This utility model relates to the technical field of sand removal from sedimentation tanks in sewage treatment plants, and in particular to a dual-pump device for flushing and removing sludge and sand from sedimentation tanks. Background Technology

[0002] Currently, the essential process stage in wastewater treatment plants nationwide is the sedimentation tank. The sludge entering the sedimentation tank undergoes sludge-water separation; denser sludge and sand settle in the sludge and sand hopper, while clean water flows out from the top. Sludge and sand removal is typically done using sludge pumps or gravity discharge. However, sludge and sand pumps are prone to clogging, damage, are bulky, and cumbersome to install, posing significant challenges to the operation and maintenance of sedimentation tanks in wastewater treatment plants. When using gravity discharge, the removal efficiency is greatly affected by human intervention, leading to insufficient or no discharge, which over time causes difficulties in sludge removal and frequent blockages.

The upper ends of the flushing pipe and the air source pipe are connected to a main air supply pipe, which is connected to an air source device. The upper end of the flushing pipe is also connected to a pumping pipe, which is equipped with a sludge discharge pump. A suction pipe is connected to the front end of the sludge discharge pump, and the lower end of the suction pipe extends into the supernatant in the sludge hopper of the sedimentation tank.

[0006] Both the upper end of the flushing pipe and the upper end of the air source pipe are equipped with manual valves and pneumatic valves.
