Description
Technical field
The present invention relates to a kind of mud scrapers, more particularly to efficiently circumference mud scraper, belong to sewage treatment technical field of environment protection equipment.
Background technique
Currently, the precipitation unit in sewage treatment needs to collect in the sludge after precipitating, handled using bioanalysis technique
Sewage is transported outward in the biological tank of the preceding working procedure of a part of sewage backflow to precipitating after excess sludge dehydration, wherein
The sludge activity flowed back into biological tank is higher, better to the effect of sewage treatment.Therefore, in order to make biological tank activated sludge protect
A certain concentration is held, it is particularly necessary to biological tank returnedactivatedsludge.During sewage treatment, the middle part of sedimentation basin is easily heavy
The higher sludge of product activity, and inertia sludge is easily deposited in the bottom of sedimentation basin.Existing mud scraper is located at sedimentation basin center, leads to
Over-driving device realizes the driving to center transmission shaft, and the scraper arm being connected on center driving axis at the same time starts to do circumference
The work in direction, in the course of work, since driving device directly drives the work of center driving axis, the torque born is larger, long
Phase use be easy to cause stability poor, reduces the service life of equipment；After sludge is of long duration in sedimentation basin, it be easy to cause dirt
Mud hardness increases, and cleaning shoe is caused to be difficult to scrape sludge, so as to cause the reduction of blowdown mud ability.
Summary of the invention
In view of the foregoing drawbacks, the purpose of the present invention is to provide a kind of structure is simple, it is hardened to effectively prevent sinking to the bottom sludge, mentions
Height removes sludge ability, the efficient circumference mud scraper to prolong the service life.
Thus the technical scheme adopted by the invention is that:
Including newel, driving device and the service bridge being arranged in sedimentation basin, newel is externally provided with vertical frame, and frame lower end of hanging down is fixed
It is connected with sewage sludge storage cylinder, sewage sludge storage cylinder lower end is equipped with collection mud pit, and service bridge one end is mounted on sedimentation basin pool wall upper end, another
End is mounted on newel upper end, and driving device is connect with vertical frame lower end, and sewage sludge storage cylinder periphery is equipped with scraping arm and dredging tube, described
Scraping arm and dredging tube are distributed in 180 degree, and loose mud device, the scraping arm and suction mud are respectively equipped on front side of the scraping arm and dredging tube
Pipe upper end passes through drawstring and connect with vertical frame.
As a further improvement of the above technical scheme, the loose mud device includes before being fixedly mounted on scraping arm and dredging tube
The bracket of side, the pedestal lower end are equipped with loose mud rake tooth.
As a further improvement of the above technical scheme, the vertical frame interface is square or round.
As a further improvement of the above technical scheme, the collection mud pit is located at sedimentation basin bottom of pond, and the collection mud pit is equipped with
Sludge pipe, the sedimentation basin bottom are additionally provided with water inlet pipe.
The invention has the advantages that
The configuration of the present invention is simple connects scraping arm and dredging tube by using vertical frame, improves reliability, prolong the service life, energy
It is enough to be collected activated sludge and inertia sludge, loose mud device is set, effectively prevent sedimentation basin pool bottom sludge hardened, effectively mentions
High Treatment of Sludge effect.

One end is mounted on 1 pool wall upper end of sedimentation basin, and the other end is mounted on 2 upper end of newel, and driving device 3 is connect with vertical 5 lower end of frame, dirty
6 periphery of mud storage cylinder is equipped with scraping arm 7 and dredging tube 8, and the scraping arm 7 is distributed with dredging tube 8 in 180 degree, the scraping arm 7 and suction mud
The front side of pipe 8 is respectively equipped with loose mud device, and the scraping arm 7 and 8 upper end of dredging tube pass through drawstring 9 and connect with vertical frame 5.
As a further improvement of the above technical scheme, the loose mud device includes being fixedly mounted on scraping arm 7 and dredging tube 8
The bracket 10 of front side, 10 lower end of bracket are equipped with loose mud rake tooth 11.
As a further improvement of the above technical scheme, 5 interface of vertical frame is square or round.
As a further improvement of the above technical scheme, the collection mud pit is located at 1 bottom of pond of sedimentation basin, and the collection mud pit is equipped with
Sludge pipe 12,1 bottom of sedimentation basin are additionally provided with water inlet pipe 13.
