Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy smelting, and in particular to a slag removal device for an aluminum alloy smelting furnace. Background Art

[0002] An aluminum alloy melting furnace is an industrial equipment that heats aluminum and aluminum alloy raw materials to a molten state. It is usually used in the metal melting process before casting, die-casting or rolling. During the melting process, scum composed of oxides, flux residues, impurities, etc. will form on the surface of the aluminum liquid. The scum needs to be removed at specific intervals to ensure the purity of the aluminum alloy melt and the quality of subsequent processed products.

[0003] In the prior art, for the slag cleaning of a small crucible-type aluminum alloy melting furnace, manual labor is usually used instead of mechanical arms for slag removal due to the high temperature of the production environment and the low frequency of slag removal operations. Operators generally use high-temperature resistant shovels to directly remove the slag on the surface of the aluminum liquid. This operation mode not only avoids the problem of aging of precision parts of the mechanical arm at high temperatures and high maintenance costs, but also adapts to the actual needs of low-frequency slag removal. In the process of manually using high-temperature resistant shovels to remove slag, operators need to work close to the melting furnace, and after the operators pick up the slag, they also need to tilt the shovel to make the scooped aluminum liquid flow back into the melting furnace, so as to reduce the overall loss of aluminum liquid and reduce production costs.

[0004] However, the conventional method of manually removing scum on the surface of molten aluminum in a crucible aluminum alloy melting furnace has the following problems: 1. In the prior art, due to the strong fluidity and low surface tension of high-temperature molten aluminum, it is easy to cause small-scale splashing under disturbances such as scraping by a shovel or gas escape in the furnace, affecting the operating safety of the operator; 2. The operator's operation of tilting the shovel to make the molten aluminum reflux will also cause small-scale splashing of the molten aluminum, and the scum is also more likely to be partially separated and fall back into the molten aluminum during the tilting process due to insufficient adhesion between the shovel and the shovel, thereby not only causing large-scale splashing of the high-temperature molten aluminum, further increasing the operating risks of the operators, but also causing an increase in the loss of molten aluminum and production costs; 3. The falling of scum will also force the operator to repeatedly pick up the residual scum. After multiple operations, the operator will suffer from physical exhaustion and fatigue, resulting in reduced movement stability, further increasing the probability of scum falling back, significantly threatening the safety of production operations and the stability of product production and processing.

[0038] See also Figure 1 , Figure 3 and Figure 4 The transmission part 35 includes a sliding column 351 that is slidably arranged in the sliding groove and moves up and down. A driving column 352 is fixedly arranged on the lower side of the sliding column 351. A sliding shaft 1 353 that is slidably connected to the corresponding linear groove 2 is fixedly arranged on the sliding column 351 front and back symmetrically. A connecting rod 3 is fixedly arranged on the end of the sliding shaft 1 353 away from the sliding column 351, and a sliding shaft 2 354 that slidably cooperates with the V-shaped groove 322 is fixedly arranged on the upper end of the opposite side of the front and rear symmetrical connecting rods 3.

[0039] By manually driving the swivel seat 331 and the receiving frame 332 to rotate around the T-shaped connecting shaft 323, the limiting sleeve 341 and the guide platform 342 rotate synchronously, and the limiting sleeve 341 drives the sliding column 351 and the sliding shaft 1 353 to rotate synchronously. The sliding shaft 1 353 then drives the sliding shaft 2 354 to slide along the V-shaped groove 322 through the connecting rod 3. Under the guidance of the V-shaped groove 322, the sliding shaft 2 354 then drives the corresponding sliding shaft 1 353 to slide continuously up and down along the corresponding linear groove 2 through the connecting rod 3. The sliding shaft 2 354 then drives the sliding column 351 and the driving column 352 to move synchronously and continuously up and down reciprocatingly along the limiting sleeve 341.

[0040] See also Figure 1 , Figure 3 and Figure 4The material guide portion 36 includes a sliding shaft 361 slidably set in a linear groove 3, and a material guide plate 362 is fixedly set on the lower side of the sliding shaft 361. The material guide plate 362 is composed of an arc-shaped straight plate and an arc-shaped inclined plate distributed up and down. The arc-shaped straight plate is connected to the driving column 352 through a transmission rod 363 hingedly installed up and down.

[0041] The U-shaped frame 21 is driven by the moving wheel to move forward and backward until the guide column 321 is coaxial with the smelting furnace 1, and then the guide column 321 and the receiving frame 332 are driven by the hydraulic cylinder 31 to move downward, and the receiving frame 332 then drives the guide plate 362 to move downward synchronously through the limiting sleeve 341 and the guide platform 342 until the arc-shaped inclined plate is completely immersed in the molten high-temperature aluminum liquid. At this time, the receiving frame 332 is driven to rotate, and the sliding column 351 and the driving column 352 are moved upward accordingly under the action of the V-shaped groove 322 on the guide column 321. The driving column 352 then drives the guide plate 362 and the sliding shaft 361 to move back and forth along the corresponding linear groove 3 through the transmission rod 363. The guide plate 362 then guides and drives the slag on the surface of the aluminum liquid to the edge of the smelting furnace 1 intermittently, so that the slag quickly gathers at the edge of the smelting furnace 1. The arc-shaped inclined plate can not only reduce the resistance encountered by the guide plate 362 when entering the aluminum liquid, thereby reducing the splashing of the aluminum liquid caused by the disturbance to a certain extent, but also disperse the slag near the middle of the aluminum liquid surface to the edge of the smelting furnace 1.

[0042] See also Figure 1 The slag discharge mechanism 4 includes a movable rod 41 that is movably arranged in a through groove inside the receiving frame 332. The right end of the movable rod 41 is provided with a linked slag discharge part 42 that cooperates with the material guiding part 36 to scoop up the floating slag. The left end of the movable rod 41 is provided with a docking adjustment part 43 that cooperates with the docking positioning part 23 and the hydraulic cylinder 31 to perform docking positioning and assist in slag discharge.

[0043] See also Figure 1 , Figure 3 and Figure 5 The linked slag discharge part 42 includes a slag collecting cover 421 which is fixedly arranged on the lower side of the movable rod 41 and on the right side of the guide plate 362 through a connecting rod 4. The front side of the slag collecting cover 421 is an opening, and a plurality of drainage grooves 422 which are connected inside and outside are evenly arranged on the upper and lower sides of the rear side of the slag collecting cover 421, wherein the width of the drainage grooves 422 is smaller than the size of the slag, and a shovel plate 423 is fixedly arranged on the front side of the slag collecting cover 421.

[0044] When the hydraulic cylinder 31 drives the guide plate 362 to move downward into the aluminum liquid through the receiving frame 332, the receiving frame 332 drives the movable rod 41 to move downward synchronously, and the movable rod 41 drives the slag collecting cover 421 and the shovel plate 423 to move downward synchronously through the connecting rod 4 until the shovel plate 423 is completely immersed in the aluminum liquid. At the same time, the slag collecting cover 421 and the shovel plate 423 are adjusted left and right by the movable rod 41 to make them stably fit with the inner wall of the smelting furnace 1, and then the left end of the movable rod 41 and the receiving frame 332 are manually driven to rotate around the T-shaped connecting shaft 323 in a directional manner (such as Figure 1 As shown in the figure, the guide plate 362 synchronously guides and drives the slag to the edge of the smelting furnace 1 intermittently, and the shovel plate 423 synchronously shovels the slag gathered at the edge of the smelting furnace 1 into the slag collecting cover 421 along the inner wall of the smelting furnace 1. The above-mentioned operation method can expand the operating radius of the operator through the movable rod 41, so that the operator can maintain a farther safety distance from the smelting furnace 1, and avoid the splashing of high-temperature aluminum liquid to threaten the operator.

[0045] See also Figure 1 and Figure 2 The docking adjustment part 43 includes an adjustment plate 431 fixedly arranged at the left end of the movable rod 41, a return handle 432 is fixedly arranged on the lower side of the adjustment plate 431, and two docking holes are opened on the adjustment plate 431 to pass through the left and right sides. The docking hole 2 is positioned by plugging with the docking hole 1 through the pin 1, and the docking hole 2 is positioned by plugging with the linear groove 1 through the pin 2.

[0046] When a sufficient amount of slag is shoveled into the slag collecting cover 421 and the adjusting plate 431 is on the left, the movable rod 41 is first pulled leftward to make the slag collecting cover 421 that is in contact with the inner wall of the smelting furnace 1 close to the middle of the smelting furnace 1 by a certain distance, and then the adjusting plate 431 and the movable rod 41 are driven to rotate forward by a specific angle through the return handle 432, and the connecting rod 4 drives the slag collecting cover 421 to rotate synchronously therewith until the docking hole 2 is aligned with the docking hole 1 on the docking seat 1 231, and the docking hole 2 is plugged and positioned with the docking hole 1 through the latch 1. At this time, the slag shoveled into the slag collecting cover 421 is in the slag collecting cover The slag hood 421 cannot fall back into the molten aluminum, and the molten aluminum flowing into the slag collecting hood 421 then slowly and steadily flows back into the smelting furnace 1 through the drain trough 422. The above-mentioned operation method not only avoids the large-scale splashing of high-temperature molten aluminum caused by the falling slag, reduces the overall loss of molten aluminum and production costs, but also reduces the number of times the operator repeatedly picks up the slag, and also reduces the physical exertion of the operator in manually supporting and rotating the slag collecting hood 421 forward at a specific angle to assist the reflux of the molten aluminum, thereby reducing the operator's workload and reducing labor costs.

[0047] When the aluminum liquid in the slag collecting cover 421 completely flows back into the smelting furnace 1 and the slag needs to be dumped, the slag collecting cover 421 is first driven by the hydraulic cylinder 31 to move upward until it is completely out of the smelting furnace 1, and then the slag collecting cover 421 is driven to move to the right by the movable rod 41 until it is completely out of the top of the smelting furnace 1, and then the adjustment plate 431 and the movable rod 41 are driven to rotate backward to a specific angle by the return handle 432, and the connecting rod 4 drives the slag collecting cover 421 to rotate synchronously therewith until the docking hole 2 is aligned with the lower end of the linear groove 1 on the docking seat 232, and the docking hole 2 is plugged into the lower end of the linear groove 1 by the latch 2. The slag collecting cover 421 is in the position, at this time, the slag in the slag collecting cover 421 automatically falls down from the opening on the front side of the slag collecting cover 421 under the action of gravity. If there is slag adhering to the inside of the slag collecting cover 421, the movable rod 41 and the slag collecting cover 421 are driven by the hydraulic cylinder 31 to swing back and forth up and down along the linear groove until the slag inside the slag collecting cover 421 is completely removed. The above-mentioned operation method not only reduces the physical consumption of the operator by manually supporting and rotating the slag collecting cover 421 to a specific angle to make the slag fall off, further reduces the operating burden of the operator, but also improves the effect and efficiency of slag dumping and overall cleaning and removal.
