Sludge-blockage-preventing desliming machine for sewage treatment

Abstract

The present invention discloses a sludge-blockage-preventing desliming machine for sewage treatment, which comprises a shell, a fixed bottom plate is fixedly connected to the outer bottom wall of theshell, and supporting columns are arranged at the two ends of the fixed bottom plate in a sleeving mode. In the rapid dewatering process, the fixed shaft and the inner barrel rotate relatively, at themoment, the connecting rod and the spiral blade are matched to stir sludge in an overturning mode and scatter the sludge, the dewatering quality of the sludge is greatly improved, and along with rotation of the inner barrel, the sludge scraping plate continuously scrapes off the sludge on the inner side wall of the inner barrel. According to the sludge dewatering device, sludge is effectively prevented from being accumulated in the dewatering holes of the inner barrel to form blockage, and the sludge dewatering efficiency can be improved; meanwhile, the pressure springs and the fixing columnsare matched to damp the fixing bottom plate in the vertical direction, and the buffer pads buffer the fixing bottom plate in the horizontal direction; the two components are combined to release forceand buffer vibration generated by working of the desliming machine, damping of the desliming machine is achieved, and therefore stability of the desliming machine in the working process is guaranteed, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a deslimer for sewage treatment which prevents sludge clogging. Background technique [0002] At present, with the continuous development of science and technology, production-oriented fields such as industry and coal mining have made rapid progress, followed by more and more sewage generated, and a large amount of sludge will be generated during the treatment of these sewage . Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. In the process of sewage treatment, many harmful substances in sewage will be hidden in sludge and difficult to purify, so Sludge needs to be separated from sewage for separate treatment. [0003] Sludge often needs to be dehydrated during treatment. At this time, a dehydrator is needed. The working principle of the dehydrator is to use a high-speed ...

AI Technical Summary

Problems solved by technology

[0003] Sludge often needs to be dehydrated during treatment. At this time, a dehydrator is needed. The working principle of the dehydrator is to use a high-speed rotating centrifugal cylinder to remove the water in the sludge. However, there are many problems in modern dehydrators. Defects, such as the high viscosity of the sludge, the sludge is easy to block the dehydration hole of the dehydrator when the dehydrator is working, resulting in a decrease in dehydration efficiency, and at the same time, the centrifugal cylinder is prone to large vibrations when rotating at high speed, resulting in premature damage to the device.
