[0002] The operating principle of the aluminum refining degasser is to use a graphite rotor to blow inert gas into the molten aluminum. The rotating graphite rotor breaks the gas into a large number of tiny, diffuse bubbles, which are evenly dispersed throughout the molten aluminum. These bubbles, relying on gas partial pressure differences and surface adsorption, absorb hydrogen and impurities such as oxide inclusions. As the bubbles slowly rise, they carry the absorbed hydrogen and impurities to the surface of the molten aluminum, thereby removing hydrogen and slag from the molten aluminum.

[0003] However, the degassing machine in the prior art cannot automatically clean the aluminum liquid condensed on the surface of the graphite rotor, and needs to be cleaned manually, which is time-consuming and labor-intensive. Manual cleaning cannot ensure the cleaning effect of the graphite rotor, and residual aluminum liquid is likely to adhere to the surface of the graphite rotor, shortening the service life of the graphite rotor and increasing maintenance costs.

DETAILED DESCRIPTION

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] See also Figures 1-6As shown, a graphite rotor surface anti-adhesion type aluminum liquid refining degasser includes a base plate 100 and a degasser body 101. The degasser body 101 is arranged on the base plate 100. The working end of the degasser body 101 is provided with a rotatable graphite rotor 102. The top of the degasser body 101 is provided with a top plate 105, and the top plate 105 is provided with a side plate 106. The side plate 106 is provided with a cleaning mechanism 200. The cleaning mechanism 200 includes a scraper 209, a moving component that drives the scraper 209 to move up and down along the vertical direction of the graphite rotor 102, and an adjusting component that adjusts the distance between the scraper 209 and the graphite rotor 102. The moving component is provided on the side plate 106, the adjusting component is provided on the moving component, the scraper 209 is provided on the adjusting component, and the adjusting component is also provided with a buffer mechanism 300.

[0025] When the graphite rotor 102 needs to be cleaned, the adjustment component is used to make the scraper 209 abut against the outer wall of the graphite rotor 102, and the graphite rotor 102 is driven to rotate by the degasser body 101. The scraper 209 is then driven up and down by the moving component to scrape off the aluminum liquid attached to the surface of the graphite rotor 102. The buffer mechanism 300 is used to reduce the impact force and wear of the scraper 209 on the graphite rotor 102, thereby avoiding scraping off the protective layer on the surface of the graphite rotor 102.

[0026] By providing the cleaning mechanism 200, the aluminum liquid adhering to the surface of the graphite rotor 102 can be completely scraped off, thereby preventing residual aluminum liquid from adhering to the surface of the graphite rotor 102, extending the service life of the graphite rotor 102, and reducing maintenance costs. The scraped aluminum liquid falls back into the aluminum liquid tank, reducing the waste of aluminum liquid. By providing the buffer mechanism 300, the scraper 209 is in soft contact with the graphite rotor 102, preventing the scraper 209 from scratching the surface of the graphite rotor 102 due to excessive force.

[0027] See also Figure 1-Figure 3 As shown, the moving assembly includes a first motor 201 and a reciprocating screw 202. The first motor 201 is arranged on the top plate 105, and the reciprocating screw 202 is rotatably arranged on the side plate 106. The working end of the first motor 201 is transmission-connected to the top of the reciprocating screw 202. A first guide rod 203 is fixedly provided on the side plate 106. The first guide rod 203 is arranged parallel to the reciprocating screw 202. A moving block 204 is provided on the reciprocating screw 202 and the first guide rod 203.

[0028] When the scraper 209 needs to be moved, the first motor 201 drives the reciprocating screw 202 to rotate. The rotation of the reciprocating screw 202 drives the moving block 204 to reciprocate along the reciprocating screw 202. The adjustment assembly then drives the scraper 209 up and down, facilitating the comprehensive scraping of molten aluminum adhered to the surface of the graphite rotor 102. This solves the problem of how to drive the scraper 209 to move.

[0029] See also Figures 1-4 As shown, the adjustment component includes a second motor 205 and a screw 206. The second motor 205 is arranged on the moving block 204, and the screw 206 is rotatably arranged on the moving block 204. The working end of the second motor 205 is transmission-connected with the end of the screw 206. A second guide rod 207 is symmetrically provided on the moving block 204 along the central axis of the screw 206. An adjustment block 208 is provided on the screw 206 and the second guide rod 207, and a scraper 209 is hingedly provided on the adjustment block 208.

[0030] The screw 206 is driven to rotate by the second motor 205, and the screw 206 is used to drive the adjustment block 208 to move. The adjustment block 208 drives the scraper 209 to move, so that the distance between the scraper 209 and the graphite rotor 102 can be easily adjusted, so that the scraper 209 abuts against the surface of the graphite rotor 102, so that the scraper 209 can scrape off the molten aluminum adhering to the surface of the graphite rotor 102, thereby more effectively cleaning the molten aluminum adhering to the surface of the graphite rotor 102 and extending the service life of the graphite rotor 102. The second guide rod 207 is provided to make the adjustment block 208 move more smoothly and improve the scraping effect of the scraper 209.

[0031] See also Figure 3-Figure 5 As shown, the regulating block 208 is symmetrically provided with nozzles 210 along the central axis of the scraper 209 , and the regulating block 208 is connected with a connector 211 .

[0032] An external jet device is connected through the connector 211, and the compressed air is blown to the surface of the graphite rotor 102 using the nozzle 210 to remove loose impurities and aluminum slag on the surface of the graphite rotor 102, thereby further cleaning the surface of the graphite rotor 102. This can quickly and effectively clean the surface of the graphite rotor 102, improve the cleaning effect of the aluminum liquid refining degasser, and prevent aluminum liquid from remaining on the surface of the graphite rotor 102.

[0033] See also Figure 4-Figure 6 As shown, the buffer mechanism 300 includes a fixed plate 303, a sliding rod 304 and a pressure plate 307. The fixed plate 303 is fixed on the adjusting block 208 and is located above the scraper 209. The sliding rod 304 is provided through the fixed plate 303. Two sliding rods 304 are symmetrically provided along the central axis of the fixed plate 303. The pressure plate 307 is fixed to the bottom of the two sliding rods 304. The two sliding rods 304 are both provided with a spring 306. The two ends of the spring 306 are respectively in contact with the bottom of the fixed plate 303 and the top of the pressure plate 307. The top of the two sliding rods 304 is provided with a limit block 305.

[0034] When the scraper 209 moves up and down, resistance is generated between the scraper 209 and the surface of the graphite rotor 102, causing the scraper 209 to tilt slightly, squeezing the pressure plate 307, driving the pressure plate 307 to move upward, compressing the spring 306, and acting as a buffer for the scraper 209, avoiding hard contact between the scraper 209 and the graphite rotor 102, thereby reducing the impact force and wear on the scraper 209 and the graphite rotor 102, extending the service life of the scraper 209 and the graphite rotor 102, and reducing the cost of maintenance and replacement.

[0035] See also Figure 5-Figure 6 As shown, two sliding grooves 308 are provided on the adjustment block 208 , and sliders 309 are slidably fitted in the two sliding grooves 308 , and the side walls of the sliders 309 are fixedly connected to the side walls of the pressure plate 307 .

[0036] The sliding of the slider 309 in the slide groove 308 guides the movement of the pressure plate 307, making the pressure plate 307 move more smoothly, ensuring that the pressure plate 307 always presses the scraper 209, preventing the scraper 209 from having poor contact with the surface of the graphite rotor 102, and enhancing the scraping effect of the scraper 209.

[0037] See also Figure 5-Figure 6 As shown, the adjusting block 208 and the scraper 209 are each provided with a corresponding buckle 301 , and the buckle 301 is provided with a tension spring 302 .

[0038] The tension spring 302 is used to keep the scraper 209 in a horizontal state, which facilitates the scraper 209 to fully contact the graphite rotor 102, and efficiently scrapes away the molten aluminum adhering to the surface of the graphite rotor 102, thereby improving the flexibility of the molten aluminum refining degasser and the cleaning efficiency of the molten aluminum refining degasser.

[0039] See also Figure 1-Figure 2 As shown, universal wheels 103 are provided at the four corners of the bottom of the base plate 100 , and a push handle 104 is provided on one side of the top of the base plate 100 .

[0040] When the position of the degasser body 101 needs to be adjusted, the staff can push the push handle 104 to drive the universal wheel 103 to move, and then move the degasser body 101 so that the degasser body 101 reaches the appropriate position. The operation is simple, which improves the convenience and practicality of the aluminum liquid refining degasser.

[0041] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
