Cleaning device for cleaning inner wall of sewage tank based on gravity variation

Abstract

The invention relates to the technical field of sewage treatment, and discloses a cleaning device for cleaning the inner wall of a sewage tank based on gravity variation. The cleaning device comprisesa sewage tank body. A buffering rail is arranged in the sewage tank body. A pressing block is arranged on the lower side of the buffering rail. A shaft rod is connected with the bottom end of a pressing column. A pushing block is connected with the lower side of the shaft rod. A rotating outer circle gear is connected with the outer side of the pushing block and meshes with an eccentric wheel. The eccentric wheel is connected with the shaft rod. The shaft rod is connected with a cleaning block. The sewage tank body is provided with a sewage outlet. When the cleaning device for cleaning the inner wall of the sewage tank based on gravity variation is used, dirt and a large amount of sludge can be attached to the inner wall and the bottom of the sewage tank body due to long-term use, after too much sludge is accumulated, the buffering rail can be pressed to move under the weight of the sludge at the bottom so as to press the pressing block, connecting rods press the two sides so as to decompose pressing force under the action of springs, and rigid damage is avoided.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a cleaning device for cleaning the inner wall of a sewage tank based on the change of gravity. Background technique [0002] Sewage treatment is the process of purifying sewage in order to make it meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering and other fields, and is increasingly entering the daily life of ordinary people. [0003] Most of the existing sewage treatment is to put the sewage into the same container, and the sewage is centrally treated by other means such as precipitation filtration or electrolysis to achieve the purpose of purifying the sewage, but no matter what kind of sewage treatment method is used, it is necessary to Due to the excessive amount ...

Problems solved by technology

[0003] Most of the existing sewage treatment is to concentrate the sewage into the same container, and to carry out centralized treatment of the sewage through other means such as sedimentation filtration or electrolysis to achieve the purpose of purifying the sewage, but no matter what kind of sewage treatment method is adopted, it will eventually need Due to the excessive impurities in the sewage container, after several rounds of sewage purification, a large amount of impurities and scale will accumulate on the inner wall of the container, which will not only make the subsequent sewage purification impossible Good effect, and if these impurities are not removed in time, the follow-up cleaning will become more difficult after a long time. At present, most of the cleaning methods are sprayed by high-pressure water guns, which will undoubtedly cause a lot of waste of water resources. And often because of the slackness of the staff, it is difficult to clean the inside of the sewage tank
