[0002] When a metal or other material is heated to a high temperature and melted in a smelting furnace for subsequent casting or processing, in order to ensure the cleanliness of the interior of the smelting furnace and thus ensure the stability of the subsequent melting operation, it is necessary to regularly remove the waste slag remaining on the inner wall of the smelting furnace. Most of the existing slag removal devices in the smelting furnace are arranged at the bottom of the inner cavity of the smelting furnace. Through a pushing mechanism, the waste slag at the bottom of the inner cavity of the smelting furnace is guided to the second slag outlet to achieve the effect of removing the waste slag. However, this slag cleaning device cannot reach the waste slag adhered to the inner wall of the smelting furnace, and thus cannot clean the waste slag on the inner wall of the smelting furnace. This obviously has a large defect. For this reason, we have proposed a smelting furnace that is convenient for slag removal. Utility Model Content

A movable rod 24, a plurality of scrapers 25 and a brush head 23 are arranged on the periphery of the upper end of the driving rod 24, and the plurality of scrapers 25 and the brush heads 23 are evenly spaced and distributed in a circular array on the periphery of the driving rod 24, and the scraper 25 is arranged on the upper side of the brush head 23, a driving sleeve 31 is welded to the upper end of the output shaft of the upper end of the first motor 2, and a movable block 34 which is plugged into the driving sleeve 31 is welded to the lower end face of the driving rod 24, a movable plate 33 is sleeved on the periphery of the driving sleeve 31, and the movable block 34 is rotatably installed in the movable plate 33, and a second motor 3 is fixedly installed on the top of the inner cavity of the power cavity 12 by bolts, and a threaded rod 32 is welded to the lower end of the output shaft of the lower end of the second motor 3, and the threaded rod 32 is threadedly connected to the movable plate 33.

[0028] Specifically, a second motor 3 is provided, and the threaded rod 32 is driven to rotate through its output shaft, and the threaded connection between the threaded rod 32 and the movable plate 33 can drive the movable plate 33 to move up and down, so that the movable plate 33 and the movable block 34 can be driven to move up and down through the rotational connection between the movable plate 33 and the movable block 34, so as to achieve the effect of adjusting the height of the scraper 25 and the brush head 23, and then the first motor 2 can drive the drive sleeve 31 and the drive rod 24 to rotate through its output shaft, so as to drive the scraper 25 and the brush head 23 to rotate on the inner wall of the smelting chamber 11, and then the waste slag remaining on the inner wall of the smelting chamber 11 can be cleaned.

[0029] As a further description of the above technical solution: the upper end surface of the first partition 21 is flush with the lower end of the first slag outlet 15, each scraper 25 is spirally arranged, and multiple scrapers 25 are evenly spaced and distributed in a circular array on the periphery of the driving rod 24, a first slot 211 is opened on the inner side of the first partition 21, and a second slot 221 is opened on the periphery of the second partition 22. The number and shape of the scrapers 25 are the same as the first slot 211 and the second slot 221. A support plate 26 is fixedly installed on the upper end surface of the driving rod 24, and multiple scrapers 25 are welded and installed on the upper end of the support plate 26, and the outer diameter of the second partition 22 is twice the outer diameter of the support plate 26.

[0030] Specifically, the scraper 25 is spirally arranged so that when it rotates, it can guide the waste slag on its upper end surface, which is convenient for the waste slag to remain on the upper end surface of the scraper 25. A first partition 21 and a second partition 22 are arranged, and through the plug-in effect between the scraper 25 and the first slot 211 and the second slot 221, when the scraper 25 and the brush head 23 are retracted into the power chamber 12, the lower end of the smelting chamber 11 can be sealed, and the upper end of the scraper 25 can be prevented from protruding from the upper end of the first partition 21, thereby ensuring the metal smelting quality during the smelting operation in the smelting chamber 11.

[0031] As a further description of the above technical solution: a connecting seat 231 is integrally formed on the outer periphery of the upper side of the driving rod 24, a spring 232 and a telescopic sleeve 233 that are plugged into each other are fixedly installed between the connecting seat 231 and each brush head 23, and the spring 232 is arranged in the inner cavity of the telescopic sleeve 233.

[0032] Specifically, a spring 232 is arranged between the driving rod 24 and each brush head 23. When the driving rod 24 rotates, the brush head 23 can be thrown outward to contact the inner wall of the smelting chamber 11, so that the rotating brush head 23 can clean the waste slag on the inner wall of the smelting chamber 11. When the driving rod 24 stops rotating, the brush head 23 shrinks inward, so that when the brush head 23 descends and shrinks into the power chamber 12, it can avoid the brush head 23 from contacting the inside of the first partition 21.

[0033] As a further description of the above technical solution: through holes 332 for plugging into the drive sleeve 31 and threaded holes 331 for threaded connection with the threaded rod 32 are provided on both sides of the upper end of the movable plate 33, a plug cavity 311 for plugging into the movable block 34 and the drive rod 24 is provided in the middle of the upper end of the drive sleeve 31, a limited sliding cavity 312 is provided on the periphery of the plug cavity 311, a first limiting sliding block 341 slidably connected to the limiting sliding cavity 312 is fixedly installed on the periphery of the movable block 34, an annular rotating cavity 333 is provided in the through hole 332, and a second limiting sliding block 342 slidably connected to the inner cavity of the annular rotating cavity 333 is fixedly installed on the outer end of the first limiting sliding block 341.

[0034] Specifically, through the threaded connection between the threaded hole 331 and the threaded rod 32, and the rotational connection between the second limit slider 342 and the annular rotating chamber 333, the rotating threaded rod 32 can drive the movable block 34 and the driving rod 24 to move up and down, and through the sliding connection between the first limit slider 341 and the limit sliding chamber 312, the rotating driving sleeve 31 can drive the driving rod 24 to rotate therewith.

[0035] Working principle: When cleaning the waste slag remaining on the inner wall of the smelting chamber 11, start the second motor 3, and the second motor 3 drives the threaded rod 32 to rotate through its output shaft. The driving sleeve 31 is connected with the through hole 332 through the plug connection to limit the movement direction of the movable plate 33, so that the rotating threaded rod 32 can drive the movable plate 33 to move upward through the threaded connection between the threaded hole 331, and the movable plate 33 moving upward can drive the movable block 34 to move upward in the driving sleeve 31 through the rotation connection between the second limiting slider 342 and the annular rotating chamber 333, so that the scraper 25 and the brush head 23 can be extended upward into the smelting chamber 11, and the heights of the two can be adjusted.

[0036] The first motor 2 is started, and the first motor 2 drives the driving sleeve 31 to rotate through its output shaft. The rotating driving sleeve 31 can drive the driving rod 24 to rotate with it through the sliding cooperation between the limiting sliding cavity 312 and the first limiting sliding block 341, thereby driving the scraper 25 and the brush head 23 to rotate in the smelting chamber 11. The metal waste slag adhering to the inner wall of the smelting chamber 11 can be scraped off by the rotating scraper 25, and the rotating driving rod 24 can throw the brush head 23 outward so that the brush head 23 contacts the inner wall of the smelting chamber 11, and the dust on the inner wall of the smelting chamber 11 can be cleaned. The scraped waste slag, dust and other impurities will fall down to the bottom surface of the inner cavity of the smelting chamber 11. Since the bottom surface of the inner cavity of the smelting chamber 11 is inclined, it can be combined with the second slag outlet 16 on its outer side to lead out the waste slag, dust and other impurities.

[0037] When the first motor 2 is turned off and the driving rod 24 stops rotating, the spring 232 can drive each brush head 23 to reset inward, so that each brush head 23 shrinks to the inner side below the second partition 22, and the second motor 3 is started to rotate in the opposite direction, which is opposite to the above process, and drives the driving rod 24 to move downward, so that the scraper 25 and the brush head 23 reset downward. At this time, the inward contraction of the brush head 23 can avoid contact with the inner side of the first partition 21, and because the contact surface between the second partition 22 and the first partition 21 is inclined, the second partition 22 can be snapped onto the upper end of the first partition 21, and the scraper 25 can avoid the upper end of the scraper 25 protruding from the upper end of the first partition 21 through the plug-in cooperation between the scraper 25 and the first slot 211 and the second slot 221.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
