DETAILED DESCRIPTION

[0021] See also Figures 1 to 4 , a waste slag cleaning device for an electric furnace, comprising an electric furnace 2, a first movable frame 3 and a second movable frame 4 are respectively provided on the left and right sides of the electric furnace 2, a cleaning structure is provided below the first movable frame 3, the cleaning structure comprises a mounting plate 302, a second motor 303 is mounted on the lower end surface of the mounting plate 302, an output end of the second motor 303 is fixedly connected to a cleaning groove 304, a cleaning brush 306 is mounted on the outer wall of the cleaning groove 304, a scraper 305 located above the cleaning brush 306 is mounted on the outer wall of the cleaning groove 304, and a first cylinder 301 with an output end fixedly connected to the mounting plate 302 is mounted on the upper end surface of the first movable frame 3;

[0022] A slag suction structure is provided below the second movable frame 4, and the slag suction structure includes a mounting frame 402, a collecting bin 403 is installed on the lower end face of the mounting frame 402, the upper end face of the collecting bin 403 is connected to a suction pump 404, the lower end face of the collecting bin 403 is fixedly connected to a dust suction bin 406, the lower end face of the dust suction bin 406 is connected to a plurality of dust suction ports 407, and a dust suction pipe 408 is connected between the left and right sides of the dust suction bin 406 and the collecting bin 403, and a second cylinder 401 with an output end fixedly connected to the mounting frame 402 is installed on the upper end face of the second movable frame 4.

[0023] The cleaning brush 306 then cleans the inner wall of the electric furnace 2 and the cleaning trough 304 is cleaned by the cleaning plate 305 and the cleaning brush 306.

[0024] Secondly, the cleaning structure is moved out of the electric furnace 2, and the second movable frame 4 is moved close to the electric furnace 2, so that the slag suction structure moves down into the electric furnace 2 through the second cylinder 401, and the suction pump 404 works at the same time. The waste slag and waste debris remaining in the electric furnace 2 can be adsorbed into the dust suction bin 406 through the dust suction port 407, and then enter the collection bin 403 for centralized collection through the dust suction pipe 408. As the second cylinder 401 extends and contracts, the dust suction structure can be driven to move up and down in the electric furnace 2, and then the electric furnace 2 can be fully adsorbed and cleaned to prevent the residual waste slag and waste debris from affecting the next use of the electric furnace 2.

[0025] As a technical optimization solution of the present invention, a slag collecting trough 307 is provided below the cleaning trough 304 , and a connecting rod 308 is fixedly connected between the lower end surface of the cleaning trough 304 and the slag collecting trough 307 .

[0026] In this embodiment, the slag collecting trough 307 is fixed by a connecting rod 308 , and the slag collecting trough 307 can be used to collect waste slag cleaned by the cleaning brush 306 .

[0027] As a technical optimization solution of the present invention, a fixed seat 1 is provided on both sides of the electric furnace 2. The upper end surfaces of the two fixed seats 1 are provided with grooves 101 whose bottoms are slidingly connected to the first movable frame 3 and the second movable frame 4. The interiors of the two grooves 101 are rotatably connected to screws 102 that are threadedly connected to the first movable frame 3 and the second movable frame 4. The outer walls of the two fixed seats 1 are installed with first motors 103 whose output ends are fixedly connected to the screws 102.

[0028] In this embodiment, the first motor 103 drives the screw 102 to rotate, thereby moving the first movable frame 3 and the second movable frame 4 closer to or farther from the electric furnace 2 , thereby facilitating the cleaning of waste slag in the electric furnace 2 .

[0029] As a technical optimization solution of the present invention, two filters 405 are installed inside the collecting bin 403, and sealing plates are installed on the front ends of the collecting bin 403 and the dust collecting bin 406.

[0030] In this embodiment, the sealing plate is opened to process the filter screen 405 and the collected waste residue in the collection bin 403 .

[0031] As a technical optimization solution of the present invention, the upper end surfaces of the cleaning trough 304 and the slag collecting trough 307 are both open structures.

[0032] In this embodiment, since the upper end surfaces of the cleaning trough 304 and the slag collecting trough 307 are both open structures, the waste slag during cleaning the electric furnace 2 can smoothly fall into the cleaning trough 304 and the slag collecting trough 307.

[0033] As a technical optimization solution of the present invention, a controller 5 is installed on the outer wall of the second movable frame 4, and the first motor 103, the first cylinder 301, the second motor 303, the second cylinder 401 and the suction pump 404 are all electrically connected to the controller 5.

[0034] In this embodiment, the controller 5 can control the first motor 103 , the first cylinder 301 , the second motor 303 , the second cylinder 401 and the suction pump 404 to operate normally.

[0035] Working principle: First, when it is necessary to clean the waste slag in the electric furnace 2, the first motor 103 on the left fixed seat 1 can be driven to rotate the screw 102 to prompt the first movable frame 3 to move close to the electric furnace 2, and then the first cylinder 301 can push the cleaning structure to move downward into the electric furnace 2 until the slag collecting tank 307 contacts the bottom of the electric furnace 2. During the downward movement of the cleaning tank 304, the scraper 305 and the cleaning brush 306 can pre-clean the inner wall of the electric furnace 2. Then the first cylinder 301 is made to pull the cleaning structure upward to move upward in the electric furnace 2. At the same time, the second motor 303 drives the cleaning tank 304 to rotate, prompting the scraper 305 and the cleaning brush 306 to rotate while moving upward, and then the scraper 305 can be used to scrape off the waste slag on the inner wall of the electric furnace 2, and the cleaning brush 306 cleans the inner wall of the electric furnace 2 again. The cleaned waste slag can fall into the cleaning tank 304 and the slag collecting tank 307 for collection;

[0036] Secondly, the cleaning structure is moved out of the electric furnace 2 by the first cylinder 301, and the left screw 102 is driven to rotate by the first motor 103, so that the first movable frame 3 moves in the direction away from the electric furnace 2, and then the first motor 103 on the right fixed seat 1 drives the screw 102 to rotate, prompting the second movable frame 4 to move close to the electric furnace 2, so that the slag suction structure is pushed down by the second cylinder 401 to enter the electric furnace 2. At the same time, the suction pump 404 works, and the waste slag and waste chips remaining in the electric furnace 2 can be adsorbed into the dust suction bin 406 through the dust suction port 407, and then enter the collection bin 403 for centralized collection through the dust suction pipe 408. The waste slag can be blocked by the filter screen 405 to prevent it from entering the suction pump 404. As the second cylinder 401 is extended and retracted, the dust suction structure can be driven to move up and down in the electric furnace 2, thereby fully adsorbing and cleaning the electric furnace 2 to prevent the residual waste slag and waste chips from affecting the next use of the electric furnace 2;

[0037] Finally, the waste residues in the cleaning tank 304, the residue collecting tank 307 and the collection bin 403 can be manually processed.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
