The working bridge is overlapped at the opening of the top surface of the sedimentation tank. The working bridge is provided with a driving motor and a medicine releasing device 3. The driving motor is connected to the working bridge, the support frame, the first stirring fan 4 and the second stirring fan 5 through a rotating shaft. The upper surface of the support frame is fixedly installed with a sludge chopping device 1 through a bearing frame 8. The lower surface of the support frame is provided with a plurality of scraper blades 2. The medicine releasing device 3 is connected with the sludge chopping device 1. A sludge collecting trough 6 is opened in the sedimentation tank. The first stirring fan 4 and the second stirring fan 5 are located in the sludge collecting trough 6. A mud discharge pipe is provided at the bottom of the sedimentation tank. A mud pump 7 is installed on the mud discharge pipe. The mud discharge pipe is connected with the mud collecting trough 6. The second stirring fan 5 is close to the bottom of the mud collecting trough 6, and the fan wings of the second stirring fan 5 are close to the side wall of the mud collecting trough 6, so as to clean the sludge on the side wall. The fan wings are inclined at forty-five degrees and are arranged through The second stirring fan 5 is convenient for sweeping the sludge in the sludge collecting tank 6 into the sludge discharge pipe, which effectively prevents the accumulation and blockage of sludge, increases the sludge discharge speed, and optimizes the cleaning effect. The first stirring fan 4 is located at the sludge inlet of the sludge collecting tank 6 above it, which is convenient for breaking up and stirring the sludge to prevent coagulation. The sludge chopping device 1 can separate and crush the sludge at the bottom of the sedimentation tank, which not only makes the sludge easier to handle, but also reduces the resistance of the scraper 2 when scraping the sludge. The medicine in the medicine dispensing device 3 is preferably a sludge conditioner, which can change the surface structure of the sludge, reduce the solid surface load and specific surface area of ​​the sludge, thereby helping to improve the sludge treatment effect and speed. A number of fixed ribs are installed between the working bridge and the support frame to increase the safety of the device connection. The driving motor drives the whole to make a circular motion in the sedimentation tank to evenly treat the bottom of the sedimentation tank.

[0028] The supporting frame 8 is symmetrically arranged on both sides of the rotating shaft, and the sludge chopping device 1 is fixedly installed at one end of the supporting frame 8. The sludge chopping device 1 is centrally symmetrically arranged, and the scraper plate 2 is centrally symmetrically arranged. The symmetrical design makes the whole device evenly stressed during operation, reduces the vibration caused by uneven stress, and thus improves the stability and reliability of the equipment. During circular motion, the two centrally symmetrically arranged sludge chopping devices 1 chop and separate the sludge back and forth, the main body of the scraper plate 2 has an inclination, and the side walls on both sides of the main body of the scraper plate 2 also have an inclination, and are provided with oblique cutting edges, which can better fit the surface of the sludge and facilitate scraping.

[0029] The sludge shredding device 1 comprises a plurality of sludge shredding heads 11, a plurality of cutting knives 12, a bottom brush 13 and a connector. The plurality of sludge shredding heads 11 and the plurality of cutting knives 12 are fixedly mounted on the connector. The bottom surfaces of the plurality of cutting knives 12 are mounted with bottom brushes 13. The connector is connected to the support frame through a carrier frame 8. The number of sludge shredding heads 11 is preferably three, and the number of cutting knives 12 is preferably five. All of them are arranged to rub the edges to the maximum extent, thereby ensuring the maximization of the shredding area, thereby effectively reducing the resistance of the subsequent scraper 2. The sludge shredding head 11 is "Λ"-shaped and has a certain slope, similar to a plow blade, which can more effectively perform preliminary sludge crushing and stirring, so that the subsequent cutting knives 12 can be used for sludge shredding. The processing is smoother, and a plurality of mud crushing heads 11 are fixedly installed on the lower surface of the connector near the edge side of the plurality of cutting knives 12. The shape of the end fixedly installed with the connector is just adapted to the triangular shape of the edge of the cutting knife 12. The medicine releasing device 3 connects the supporting body, the connector and the plurality of cutting knives 12. The supporting body, the connector and the plurality of cutting knives 12 have cavities adapted to the pipes, so that the medicine can be conveniently added during the sludge chopping process to enhance the processing effect. The bottom brush 13 at the bottom of the cutting knife 12 helps to scrape the sludge attached to the bottom of the sedimentation tank during movement, which is convenient for the subsequent operation of the scraper 2, further reduces the resistance of the scraper 2, and ensures continuous and efficient operation.

[0030] The medicine dispensing device 3 includes a medicine box 31, an electric valve 32 and a nozzle 33. The medicine box 31 is installed on the working bridges on both sides of the driving motor.

The nozzle 33 is installed on the side of the plurality of cutting knives 12 close to the scraper 2. The carrier, the connector and the plurality of cutting knives 12 are internally connected. The electric valve 32 accurately controls the amount of medicine to be put in, improves the use efficiency of the medicine, and ensures the stability and Safety, the agent is transmitted to the cavity connected by the carrier, the connector and several cutting knives 12 through the pipeline, and the agent is evenly distributed in the whole sludge treatment process and fully mixed with the sludge to ensure that the agent is continuously and evenly sprayed during the cutting and scraping process, which further enhances the treatment effect. The nozzle 33 adopts a one-way anti-mud nozzle 33 to prevent sludge or other impurities from backflowing into the nozzle 33 or the pipeline, thereby keeping the nozzle 33 unobstructed and working efficiently.

[0031] The communication control methods between devices all adopt existing communication methods and are not the innovation of this application.

[0032] Working principle: When cleaning the sludge, the staff starts the driving motor, which drives the working bridge and the supporting frame to make circular motion. At this time, the two centrally symmetrical mud crushing heads 11 start to break the mud and break it up. The cutting knife 12 further breaks it up, and the bottom brush 13 scrapes the bottom surface of the sedimentation tank to reduce the resistance of the mud scraper 2 when scraping the mud, and finally evacuates the sludge, which is easily scraped off by the mud scraper 2. While making circular motion, the electric valve 32 controls the medicine box 31 to release the medicine, which is sprayed out by the nozzle 33 behind the cutting knife 12 to improve the scraping quality;

[0033] The evacuated sludge enters the mud collecting tank 6 from the inclined surface of the sedimentation tank and is further evacuated by the first stirring fan 4, and is transported by the second stirring fan 5. The sludge is swept to the mud outlet pipe and transported out by the mud pump 7. While the second stirring fan 5 rotates and transports, it also scrapes the sludge on the side wall of the mud collecting tank 6 to complete effective cleaning.
