Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] This embodiment places the cleaning device above the decomposition tank, and can be connected and controlled by the lifting component to rise or fall inside the decomposition tank. As the lifting component controls the lifting of the component, it can drive the cleaning ring and scraper that fit the inner wall of the decomposition tank to fully clean the scars on the wall of the decomposition tank. At the same time, a main cleaning ring and a secondary cleaning ring that are fixedly connected are set to clean together, which can improve the cleaning effect, achieve comprehensive and thorough cleaning of scars, and reduce the residual rate of scars. The specific implementation is as follows:

[0030] like Figures 1 to 4As shown, a decomposition tank scar cleaning device includes a support plate 2, a lifting component and a cleaning component 4. The support plate 2 is provided with a lifting component, and the movable end of the lifting component is connected to the cleaning component 4. The cleaning component 4 is movably installed inside the decomposition tank 1 and can move along the vertical direction of the decomposition tank 1. The cleaning component 4 includes a main cleaning ring 5, an auxiliary cleaning ring 6 and a scraper 12. The main cleaning ring 5 and the auxiliary cleaning ring 6 are fixedly connected and coaxially arranged. The outer circumferences of the main cleaning ring 5 and the auxiliary cleaning ring 6 are respectively provided with scrapers 12 and fit with the inner wall of the decomposition tank 1. The lifting component includes a winding motor 3 and a wire rope 8. The movable end of the winding motor 3 is connected to the wire rope 8. The bottom of the wire rope 8 is connected to the top of the main cleaning ring 5 and can drive the main cleaning ring 5 and the auxiliary cleaning ring 6 to move along the vertical direction of the decomposition tank 1. The cleaning device is placed above the decomposition tank 1, and the cleaning component 4 can be connected and controlled to rise or fall inside the decomposition tank 1 through the lifting component. As the lifting component controls the lifting of the cleaning component 4, the cleaning ring and scraper 12 that are in contact with the inner wall of the decomposition tank 1 can be driven to fully clean the scars on the wall of the decomposition tank 1. At the same time, a main cleaning ring 5 and an auxiliary cleaning ring 6 that are fixedly connected are set to perform cleaning together, which can improve the cleaning effect, achieve comprehensive and thorough cleaning of the scars, and reduce the residual rate of scars.

[0031] A winding motor 3 is installed on the top of the support plate 2, and a winding drum 7 is installed on the movable end of the winding motor 3. A wire rope 8 is wound on the winding drum 7. The winding drum 7 is driven by the winding motor 3 to wind or release the wire rope 8, thereby realizing the lifting and lowering control of the cleaning ring. The support plate 2 can be installed above the decomposition tank 1 through a fixed mounting frame.

[0032] A plurality of lifting ears 9 are installed on the top of the main cleaning ring 5, each of which is connected to a lifting rope 10, and each lifting rope 10 is connected to a lifting ring arranged at the bottom of the wire rope 8. Through the cooperation of the lifting ears 9, the lifting rope 10 and the lifting ring, the main cleaning ring 5 can be hung on the wire rope 8, so that the wire rope 8 can drive the main cleaning ring 5 to move up and down.

[0033] A plurality of connecting rods 13 are installed between the main cleaning ring 5 and the auxiliary cleaning ring 6. The main cleaning ring 5, the auxiliary cleaning ring 6 and the connecting rods 13 are all made of stainless steel. The main cleaning ring 5 and the auxiliary cleaning ring 6 can be connected and fixed by the connecting rods 13 so that they can rise and fall together.

[0034] The scraper 12 is serrated, and a wear-resistant coating 16 is provided on the outer surface of the scraper 12. The serrated scraper 12 is provided on the surface of the cleaning ring, which can better remove the scars in the decomposition tank 1. By providing the wear-resistant coating 16 on the surface of the scraper 12, the wear resistance of the scraper 12 can be improved and the service life can be increased.

[0035] The inner rings of the main cleaning ring 5 and the auxiliary cleaning ring 6 are both installed with reinforcing plates 17. By setting the reinforcing plates 17 on the two cleaning rings, the strength of the cleaning assembly 4 can be improved to make it less prone to damage.

[0036] The main cleaning ring 5 and the auxiliary cleaning ring 6 are of the same size and their outer diameters are smaller than the inner diameter of the decomposition tank 1 , which can facilitate the cleaning component 4 to extend into the bottom of the decomposition tank 1 .

[0037] Several limit plates 15 are installed on the side walls of the main cleaning ring 5 and the auxiliary cleaning ring 6, and several lifting rails 14 are formed on the inner wall of the decomposition tank 1. Several limit plates 15 match the several lifting rails 14 and can slide up and down along the lifting rails 14. Through the cooperation of the lifting rails 14 and the limit plates 15, the cleaning ring can be limited when the cleaning ring is lifted and lowered, so that it can be lifted and lowered vertically, avoiding shaking or displacement of the cleaning ring.

The counterweights 11 are easy to disassemble and assemble, and a counterweight 11 of suitable weight can be selected as needed, which is convenient for the smooth cleaning of scars.

[0040] Working principle: The cleaning device is set up above the decomposition tank, and the lifting component can be connected and controlled to rise or fall inside the decomposition tank. As the winding motor drives the wire reel, the wire rope can be driven to be wound or released. The wire rope is connected to the main cleaning ring of the cleaning component through the lifting rope and the lifting ear, thereby driving the main cleaning ring, the auxiliary cleaning ring and the scraper that fit the inner wall of the decomposition tank to comprehensively clean the scars on the wall of the decomposition tank. At the same time, with the joint cleaning cooperation of the two cleaning rings, the cleaning effect can be improved, and the comprehensive and thorough cleaning of the scars can be achieved, avoiding the situation where a single cleaning ring is not clean enough, and reducing the residual rate of scars. The limit plates set on the sides of the two cleaning rings , which can match the lifting track set on the wall of the decomposition tank, so as to limit the cleaning ring when controlling the lifting of the cleaning ring, so that it can be lifted vertically, avoiding the shaking or displacement of the cleaning ring. At the same time, a counterweight block is set at the bottom of the auxiliary cleaning ring, which can improve the stability of the cleaning assembly and avoid rollover. The counterweight block can be removed and adjusted, and the counterweight blocks of different weights can be replaced according to needs. A serrated scraper is set on the surface of the cleaning ring, which can better remove the scars in the decomposition tank. A wear-resistant coating is set on the surface of the scraper, which can improve the wear resistance of the scraper and increase its service life. The reinforcing plate set on the cleaning ring can improve the strength of the cleaning assembly itself, making it not easy to be damaged.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
