Technical Field

The utility model relates to a mud scraper technical field specifically is a sewage treatment plant mud scraper.

Background

Among the sewage treatment process, need deposit sewage to mud after will depositing is clear away through the mud scraper, and the structural strength of current mud scraper is not good, and life is low, and its stirring and the scraping of mud are efficient, are unfavorable for mud to discharge from the sludge discharge pipe, and for this reason we release a sewage treatment plant mud scraper.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sewage treatment plant mud scraper to solve the problem that proposes in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a sludge scraper of sewage treatment plant, is including fixing the vertical cycloid pinwheel speed reducer in the sedimentation tank upper end, the pivot sub-unit connection of vertical cycloid pinwheel speed reducer output has the rake, the bottom of sedimentation tank is equipped with sunken mud bucket, mud bucket bottom side is connected with the mud pipe, the lower extreme of rake is equipped with the scraper blade, the opening part of mud bucket has the bearing frame through the leg joint, the lower extreme of pivot runs through via the bearing and stretches out the back and be connected with the stirring angle steel, the bearing imbeds to the bearing frame in.

As a further optimization of the technical scheme, the upper end of the rake frame is connected to the rotating shaft through four groups of pull rods, and the rake frame is connected with the rotating shaft in a welding manner.

As a further optimization of the technical scheme, a mounting iron plate is fixed on the inner wall of the opening of the mud bucket through expansion screws, and the bottom of the support is welded on the mounting iron plate.

As a further optimization of the technical scheme, a fixing plate is arranged at the upper end of the sedimentation tank, a round hole is formed in the middle of the fixing plate, the rotating shaft penetrates through the round hole, a speed reducer base is arranged at the upper end of the fixing plate, and the vertical cycloidal pin gear speed reducer is installed on the speed reducer base.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model has the advantages that through the arrangement of the bracket, the bearing seat and the bearing, the lower end of the rotating shaft extends out through the bearing, so that the positioning support of the rotating shaft can be further realized, and the stable supporting effect of the rotating shaft is realized when the rotating shaft rotates at high speed;

the sludge in the sedimentation tank and the sludge bucket are respectively stirred under the driving of the rotating shaft through the arrangement of the rake frame and the stirring angle steel, so that the sludge can be smoothly discharged through the sludge discharge pipe;

the scraper blade can be scraped into the mud of sedimentation tank bottom sediment to the bagger, improves the speed that mud flows into to the bagger, further improves mud via mud pipe exhaust efficiency.
