Description

Technical Field

[0001] This utility model belongs to the field of sedimentation tank technology, specifically a sedimentation tank inclined plate flushing device. Background Technology

[0002] Sedimentation tanks are water purification devices that use sedimentation to remove suspended solids from water. They utilize the natural settling or coagulation process to remove suspended solids. To improve sedimentation efficiency, inclined plates are usually installed inside the sedimentation tank. These plates prevent suspended solids from being carried away by the water flow, increasing the contact area between water and solid particles, thereby improving sedimentation. The inclination angle of the inclined plates can be adjusted according to different flow rates and the size of suspended particles to achieve optimal sedimentation results. Sedimentation tanks are widely used in wastewater treatment.

[0003] To ensure the safe and stable operation of the sedimentation tank, the sludge accumulated on the inclined plates of the sedimentation tank needs to be washed regularly. The current washing method is to manually connect a fire hose for cleaning. Workers need to walk from one end of the sedimentation tank to the other with a handheld fire hose to thoroughly clean the inclined plates inside the sedimentation tank. This method not only wastes fire water resources, but also puts a lot of labor intensity on the workers. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a sedimentation tank inclined plate rinsing device that uses water from the sedimentation tank to rinse the inclined plate, thus saving water resources. Furthermore, workers can stand on a reciprocating moving trolley to rinse the inclined plate, reducing labor intensity.
