Skimming and collecting device for sewage treatment

Abstract

The invention belongs to the technical field of sewage treatment, and discloses a skimming and collecting device for sewage treatment, which comprises a settling pond, movable guide rails are fixedlymounted on the two side edges of the top of the settling pond, a support is arranged on the tops of the movable guide rails, a fixing plate is fixedly mounted at the left end of the support, and a first motor is fixedly mounted on the outer side of the fixing plate, an output shaft of the first motor is fixedly connected with a moving wheel, penetrates through the support, extends to the inner side of the support and is fixedly connected with a coupler. The first motor and a second motor drive the rotating rod and the ball screw to rotate correspondingly, the corresponding moving wheels and the corresponding moving shell are started to move, the moving wheels are responsible for driving the whole device to linearly move on the surface of the settling pond, and the ball screw drives the moving shell to transversely move; therefore, dead-corner-free cleaning of the bottom of the settling pond is achieved, the labor cost is saved, the burden of workers is relieved, and the cleaning process is efficient.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a skimming collection device for sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. field, and more and more into the daily life of ordinary people. [0003] Existing sewage treatment plants generally use sedimentation tanks to settle large particles of impurities contained in sewage during large-scale sewage treatment. However, during the bottom slag cleaning process, there will be a large amount of residual bottom slag at the bottom of the tank that cannot be solved. If it is discharged cleanly, there will be accumulation of bottom slag at the bottom ...

AI Technical Summary

Problems solved by technology

[0003] Existing sewage treatment plants generally use sedimentation tanks to settle large particles of impurities contained in sewage during large-scale sewage treatment. However, during the bottom slag cleaning process, there will be a large amount of residual bottom slag at the bottom of the tank that cannot be solved. If it is discharged cleanly, there will be accumulation of bottom slag at the bottom of the tank. This kind of bottom slag is inconvenient to clean, and long-term accumulation will greatly affect the performance of the sedimentation tank.

[0004] Generally, when cleaning the bottom slag, the water in the tank needs to be drained, so that the sedimentation work in the tank needs to be suspended, which affects the working efficiency of the sewage sedimentation tank
