Lifting type stirring structure used in sewage treatment tank

Abstract

The invention discloses a lifting type stirring structure used in a sewage treatment tank. The lifting type stirring structure comprises a bracket fixed on a stirring tank; a stirring motor is arranged on the bracket; a stirring shaft rod is arranged on a main shaft of the stirring motor; stirring blades are arranged on the stirring shaft rod; a vertical sliding groove is formed in the bracket; adriving screw rod is arranged inside the vertical sliding groove; a driving motor connected with the driving screw rod is fixed at the top of the bracket; a sliding block is arranged inside the vertical sliding groove; a stirring seat is fixed on the sliding block; a descaling strut is arranged at the middle part of the bracket; spiral stirring water guiding grooves are formed in the surface of right triangles; a circular ring is arranged on the descaling strut; and curved elastic pieces are uniformly fixed on the bottom surface of the circular ring. The lifting type stirring structure provided by the invention is reasonable in structure, and has the advantages that the stirring effect is improved and the stratification is avoided; the descaling operation on the surface of the stirring blades is completed at the same time of lifting, so that the guarantee of the stability and reliability of stirring is facilitated; and the lifting type stirring structure is good in stability and strongin practicality.

Description

Technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a lifting type stirring structure used in a sewage treatment tank. Background technique [0002] The sewage treatment tank is an indispensable part of the sewage treatment system. It mainly includes a filter tank, a sedimentation tank, a mixing tank, a reaction tank, and a clean water tank. The prior art mixing tank is mainly composed of a tank body, a support and The mixer is composed of agitator, which uses the rotation of the mixer blade to stir the sewage treatment tank. However, the agitator in the mixing tank can only rotate horizontally and cannot move vertically, and the sewage tank is prone to stratification, which makes the mixing effect very effective. At the same time, when the blades of the agitator are used for a long time, fouling is easy to occur, which affects the effect of mixing, and the applicability and practicability are limited. Summary of ...
