Mud scraping device for sewage treatment sedimentation tank

Abstract

The invention provides a sludge scraping device for a sewage treatment sedimentation tank, and relates to the field of sewage treatment. Comprising a sedimentation tank, a water inlet and a water outlet are fixedly mounted at the left top end and the right top end of the sedimentation tank respectively, and a supporting plate is fixedly mounted at the top end of the sedimentation tank. According to the sludge scraping device for the sewage treatment sedimentation tank, by arranging a spring barrel, a buffer spring and a spring rod, when sludge settled on the inner bottom wall of the sedimentation tank is treated, the spring rod can extrude the buffer spring to buffer the resistance brought by the sludge to a fender, so that the fender can stably and continuously move, and a motor is prevented from being burnt out due to short circuit; the sludge treatment device has the advantages that the sludge treatment device is provided with the sludge discharge pipe, the sludge pump and the control valve, the loose sludge can be discharged from the sludge discharge pipe by starting the sludge pump, and the sludge in the sedimentation tank can be quickly pumped out, so that space can be reserved, and dirt carried by sewage can be effectively settled.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a mud scraping device for a sewage treatment sedimentation tank. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. In the treatment of some sewage, sedimentation tanks A large amount of sludge will be deposited. If the sludge cannot be cleaned in time, the water level will be too high. At the same time, it will cause secondary pollution to the water in the sediment, which will reduce the efficiency of sewage treatment. [0003] There may be a large amount of impurities in the sludge, w...

Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. In the treatment of some sewage, sedimentation tanks A large amount of sludge will be deposited. If the sludge cannot be cleaned in time, the water level will be too high. At the same time, it will cause secondary pollution to the water in the sediment, which will reduce the efficiency of sewage treatment.

[0003] There may be a lot of impurities in the silt, which makes the silt pile up into blocks, making the silt accumulated at the bottom of the pool hard to scrape, and it is easy to scrape the silt during the scraping process Stuck, resulting in increased difficulty in cleaning and incomplete cleaning of sludge, thus reducing the sedimentation effect of sewage
