Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a sludge removal device for wastewater sedimentation tanks. Background Technology
[0002] Using sedimentation tanks to settle wastewater is a common method of wastewater treatment. During the sedimentation process, suspended particles in the wastewater settle into sludge. In order to improve the wastewater treatment effect, it is necessary to clean and remove the sludge in the sedimentation tank in a timely manner. During the wastewater sedimentation process, sludge adheres to the tank wall, which is difficult to clean.
[0003] According to patent publication number CN117282137A, a sludge removal device for sewage sedimentation tanks is disclosed, including a support frame, elastic telescopic plates, and fixing blocks. Elastic telescopic plates are installed on both the front and rear sides inside the support frame, and the upper part of each elastic telescopic plate is set as a telescopic part. This structure scrapes off the sludge attached to the elastic telescopic plates by moving the scraper to the right, avoiding the sludge from adhering to the inner wall of the elastic telescopic plates, which helps to improve the sludge removal effect.
[0004] However, in actual use, when dredging and cleaning the sludge inside the sewage sedimentation tank, it is difficult to completely clean the sludge on the edges and corners, which will gradually accumulate and affect subsequent sewage treatment. Utility Model Content

[0031] In some embodiments, according to Figure 2 , 3 As shown in Figure 4, a sludge pump 14 is fixedly installed inside the U-shaped frame 13. A first telescopic tube 15 is provided through the input end of the sludge pump 14. A central suction shell 16 is provided through one end of the first telescopic tube 15. Multiple arc-shaped suction shells 17 are connected through the outside of the central suction shell 16. The first telescopic tube 15 and the second telescopic tube 21 work together to move and extend in coordination with the sludge pump 14, while ensuring the normal operation of the sludge pump 14.
[0032] In some embodiments, according to Figure 2 , 3 As shown, triangular suction shells 18 are fixedly provided between multiple arc-shaped suction shells 17. The triangular suction shells 18 are connected to the central suction shell 16. A transmission frame 19 is fixedly provided on the rear side of the central suction shell 16.

[0036] The working principle of this utility model is as follows: (refer to the appendix of the instruction manual) Figure 1-5 As shown, the waterproof electric push rod 20 is activated to drive the transmission frame 19 to move towards the bottom of the sewage sedimentation tank. The transmission frame 19 then drives the central suction shell 16 to move downward. The central suction shell 16 then drives the arc-shaped suction shell 17 and the triangular suction shell 18 to move downward and extend into the sludge. At the same time, the sludge pump 14 is activated to suck the sludge in the sewage sedimentation tank from the arc-shaped suction shell 17 and the triangular suction shell 18 into the first telescopic pipe 15, and then into the sludge pump 14. After passing through the second telescopic pipe 21, it enters the collection box 22.
[0037] At the same time, the stepper motor is started to drive the ball screw 3 to rotate, so that the moving frame 5 moves slowly. While the moving frame 5 moves, it drives the slide 10 to move as a whole. The slide 10 then drives the movable frame 9 and the slider 8 to move at the sliding frame 7. At the same time, the electric slide rail 11 is started to drive the slide table 12 to drive the U-shaped frame 13 and the waterproof electric push rod 20 to move as a whole, so that the central suction shell 16 moves inside the sewage sedimentation tank to scoop and adsorb sludge.
[0038] When the sludge in the sewage sedimentation tank has been dredged and absorbed down to the thin adhesive layer, the waterproof electric cylinder 23 is activated to scrape the sludge attached to the surrounding walls of the sewage sedimentation tank to the bottom using the spiral scraper 25. Then, the sludge scraped to the bottom is absorbed by the movement of the arc-shaped suction shell 17 and the triangular suction shell 18.
[0039] After the sludge in the sewage sedimentation tank is cleaned, the stepper motor, electric slide rail 11 and waterproof electric push rod 20 can be started to move the central suction shell 16 to the corner of the top of the sewage sedimentation tank, so as not to affect the normal sewage treatment.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
