Sludge discharging device for sewage treatment

Abstract

The invention discloses a sludge discharging device for sewage treatment. The sludge discharging device comprises a settling chamber, and a filter chamber, a coarse channel and a fine channel which are arranged below the settling chamber. The filter chamber is provided with a sludge discharge port communicated with the settling chamber, the sludge discharge port is provided with a flow isolation mechanism, and the flow isolation mechanism is provided with a sliding flow isolation block for closing or opening the sludge discharge port; the coarse channel and the thin channel are arranged belowthe filter chamber, the upper ends of the coarse channel and the thin channel are both communicated with the filter chamber, and the lower ends of the thin channel and the coarse channel are both communicated with the converging chamber; a filtering plate is arranged in the filter chamber, a plurality of filtering holes are formed in the filtering plate, the filtering plate is located above the communicating opening of the thin channel and the converging chamber, a crushing mechanism is arranged in the coarse channel, the crushing mechanism comprises a support and a crushing blade assembly, the crushing blade assembly is installed on the support, and the support is fixed to the inner wall of the coarse channel. Sludge can be screened and crushed, the problem of blockage of a pipeline or equipment is avoided, and the sludge treatment efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of sewage treatment, and relates to the improvement of the structure and performance of a sludge treatment system, in particular to a sludge discharge device for sewage treatment. Background technique [0002] Sewage treatment can effectively protect the environment and is an effective means to realize the recycling of water resources. In the sewage treatment process, the sewage often contains a large amount of sludge, which has a greater impact on the filtration and purification of the water body. However, the sludge discharge link in the existing sewage treatment system has insufficient removal effect, which is easy to cause blockage and failure of pipelines and equipment. , Reduce the efficiency of sewage treatment. [0003] For example, the Chinese patent (application number 201721312904.3) discloses "a sludge discharge device for sewage treatment", including water pumps, primary sedimentation tanks, sprayers,...
