DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example

[0026] like Figure 1-3 As shown, it includes a refining furnace 1, a top plate 2 is provided on the top of the refining furnace 1, a filtering mechanism 3 is provided on the inner wall of the refining furnace 1, and a vibrating screening mechanism 4 is provided on the top of the top plate 2. The filtering mechanism 3 includes a fine filter 301 installed on the inner wall of the refining furnace 1, a limit knob 303 is provided on the top of the fine filter 301, and the limit knob 303 is rotatably connected to the fine filter 301, a coarse filter 304 is provided on the inner wall of the fine filter 301, a pressing plate 305 is provided on the top of the fine filter 301, and a limit hole 306 is provided on the top of the pressing plate 305.

[0027] It should be noted that, in this embodiment, the alloy steel to be refined is first fed into the feeding port 302 at the top of the top plate 2, and a fine filter 301 is embedded in the inner wall of the feeding port 302, and a coarse filter 304 is embedded in the inner wall of the fine filter 301. The fine filter 301 and the coarse filter 304 form a double-layer filtering structure. Since the mesh of the fine filter 301 is finer and the mesh of the coarse filter 304 is coarser, larger particles of impurities are blocked by the coarse filter 304, and smaller particles of impurities pass through the coarse filter 304 and are intercepted by the fine filter 301. The protrusion 307 on the side wall of the coarse filter 304 is embedded in the inner wall of the fine filter 301, which plays a role in positioning and supporting the coarse filter 304. The limit knob 303 is inserted into the limit hole 306, which fixes the pressing plate 305. When the filter needs to be replaced or cleaned, the limit knob 303 is turned to release the restriction on the pressing plate 305.

[0028] like Figure 5 As shown, the vibrating screen mechanism 4 includes a mounting block 401 symmetrically installed on the top of the top plate 2, a driving motor 402 is provided on one side of the mounting block 401, a rotating shaft 403 is axially connected to one side of the driving motor 402, a connecting plate 404 is sleeved on one side of the rotating shaft 403, a first circular shaft 405 is provided on one side of the connecting plate 404, one side of the first circular shaft 405 is embedded in the inner wall of the limiting plate 406, and the first circular shaft 405 is rotatably connected to the limiting plate 406, a connecting column 407 is provided on the top of the limiting plate 406, a second circular shaft 408 is passed through one end of the limiting plate 406, and the limiting plate 406 is rotatably connected to the second circular shaft 408, a stop block 409 is sleeved on the surface of the connecting column 407, and a nut 410 is threadedly connected to the top of the connecting column 407.

[0029] It should be noted that, in this embodiment, the mounting block 401 is symmetrically mounted on the top of the top plate 2 to provide support for the drive motor 402. After the drive motor 402 is started, it drives the rotating shaft 403 connected to one side to rotate. A connecting plate 404 is sleeved on one side of the rotating shaft 403. The rotation of the rotating shaft 403 drives the connecting plate 404 to perform a circular motion. When the connecting plate 404 performs a circular motion, the limiting plate 406 is driven to perform a reciprocating motion via the first circular shaft 405. The second circular shaft 408 serves to limit the movement direction of the limiting plate 406, so that the limiting plate 406 can only perform a reciprocating motion within a certain range. When the limiting plate 406 performs a reciprocating motion, the connecting column 407 drives the fine filter 301 and the coarse filter 304 to vibrate together.

[0030] Among them, the surface of the connecting column 407 is provided with a stopper 409, and the top of the connecting column 407 is threadedly connected with a nut 410. The stopper 409 and the nut 410 are used to fix the connection between the connecting column 407 and the fine filter 301 to prevent the connecting column 407 from escaping from the fine filter 301, thereby ensuring that the vibration screening mechanism 4 is stably connected during operation.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual Figure 1-5 First, the alloy steel to be refined is fed into the feeding port 302 on the top of the top plate 2. A fine filter 301 is embedded in the inner wall of the feeding port 302. A coarse filter 304 is embedded in the inner wall of the fine filter 301. The fine filter 301 and the coarse filter 304 form a double-layer filtering structure. Since the mesh of the fine filter 301 is finer and the mesh of the coarse filter 304 is coarser, larger particles of impurities are blocked by the coarse filter 304, and smaller particles of impurities pass through the coarse filter 304 and are intercepted by the fine filter 301. The protrusion 307 on the side wall of the coarse filter 304 is embedded in the inner wall of the fine filter 301 to position and support the coarse filter 304. The limit knob 303 is inserted into the limit hole 306 to fix the pressing sheet 305. When the filter needs to be replaced or cleaned, the limit knob 303 is turned to release the restriction on the pressing sheet 305.

[0033] The mounting block 401 is symmetrically mounted on the top of the top plate 2 to provide support for the drive motor 402. After the drive motor 402 is started, it drives the rotating shaft 403 connected to one side to rotate. A connecting plate 404 is sleeved on one side of the rotating shaft 403. The rotation of the rotating shaft 403 drives the connecting plate 404 to perform circular motion. When the connecting plate 404 performs circular motion, the limiting plate 406 is driven to perform reciprocating motion via the first circular shaft 405. The second circular shaft 408 serves to limit the movement direction of the limiting plate 406, so that the limiting plate 406 can only perform reciprocating motion within a certain range. When the limiting plate 406 performs reciprocating motion, the connecting column 407 drives the fine filter 301 and the coarse filter 304 to vibrate together.

[0034] The surface of the connecting column 407 is provided with a stopper 409, and the top of the connecting column 407 is threadedly connected with a nut 410. The stopper 409 and the nut 410 are used to fix the connection between the connecting column 407 and the fine filter 301 to prevent the connecting column 407 from escaping from the fine filter 301, thereby ensuring that the vibration screening mechanism 4 is stably connected during operation.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
