Digester sludge stirring equipment for environmental protection

Abstract

The invention discloses digester sludge stirring equipment for environmental protection. The digester sludge stirring equipment comprises a stirring rod, a stirring plate, a backflushing hooking removal device, a driving box, a mounting frame and a driving motor. According to the invention, the rotating mechanism and the impurity removing mechanism are matched with each other, under the action ofreverse rotation of a stirring shaft and the stirring rod, the stirring is uniform, when the sludge is stirred, the flowing direction of the sludge is relatively impacted, therefore, mutual counter-impact type flowing of the sludge is realized, effective stirring of the sludge is ensured, the traditional sludge stirring is prevented from flowing in a unified direction, then, the phenomenon of sinking of caked sludge and the like occurs, effective and uniform stirring cannot be achieved, and under the action of the impurity removal mechanism, impurities such as plastic contained in the sludge are hooked and removed during reverse rotation, and when the power during rotation is irregularly opened, closed and flapped back and forth, the impurities hooked and removed by the collecting, treating and stroking assembly are compressed, and meanwhile centralized collection is conducted under the cooperation of airflow in the movable ring frame.

Description

technical field [0001] The invention relates to the technical field of environmental protection, more precisely, it relates to a digester sludge stirring device for environmental protection. Background technique [0002] With the continuous improvement of people's living standards, the impact on domestic sewage has gradually been paid attention to by people. In the sludge produced by domestic sewage plants, it usually contains some domestic garbage or construction waste. When sludge is effectively degraded, it usually needs to be processed by stirring equipment before treatment. [0003] When using a sludge mixer to stir the sludge inside the digester, because the traditional stirring equipment usually rotates in the same direction when stirring, it is easy to cause impurities contained in the sludge and larger sludge The agglomeration appears in a vortex and settles down uniformly, and then it cannot be effectively stirred evenly, and the non-degradable material contained ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a digester sludge mixing equipment for environmental protection, to solve the problem in the prior art that when using a sludge mixer to stir the sludge inside the digester, due to the traditional When the stirring equipment is rotating and stirring, it usually rotates in the same direction for stirring, which will easily cause the impurities contained in the sludge and the larger sludge agglomerates to appear in a vortex-like downward direction, and then cannot carry out effective uniform stirring, and The non-degradable material contained in it cannot be self-degraded in the sludge, so that the sludge in the digester will have the defect of secondary pollution in the subsequent use process
