Description

A sewage treatment dredging device

technical field

The invention relates to the technical field of water treatment equipment, in particular to a sewage treatment dredging device.

Background technique

In the process of sewage treatment, firstly, the collected sewage needs to be uniformly settled, so that the dirt and sewage are separated and accumulated at the bottom of the settling tank to form sludge. The sludge at the bottom of the settling tank needs to be cleaned regularly. Common methods include using small excavators, artificial or sludge The pump performs dredging operations.

Manual dredging is often used in small settling tanks. The workers manually remove the silt with hand-held tools. The dredging effect is good but the work efficiency is poor. It is time-consuming and laborious and cannot meet the needs of large-scale. The dredging efficiency of excavators is good. However, the bucket is extremely easy to damage the bottom of the sedimentation tank, so its use is relatively limited; the mud pump is usually used in conjunction with manual dredging, and the workers hold the pipeline and use the mud pump to suck away the mud, but the mud at the bottom of the sedimentation tank is extremely thick. Large, and the use area of the sludge pump is also limited, so it has not been promoted.

In order to solve the above problems, a scraper driven by a mechanism is currently installed at the bottom of the sedimentation tank, and the scraper is used to scrape off the sludge at the bottom of the tank. property, there will be material running problems, and the sludge will run away from the side and top of the scraper. It needs to be repeated many times to achieve a better dredging effect, and there are differences in the scale and inclination of the settling tanks. Different settling tanks need to be made The corresponding adjustment is relatively troublesome. If a device with good desilting effect is developed based on the existing technology, it will have a positive effect on solving the above problems and improving work efficiency.
