Description

A melting furnace for aluminum ingot production Technical Field

[0001] This utility model relates to the field of aluminum melting furnace technology, specifically to a melting furnace for aluminum ingot production. Background Technology

[0002] An aluminum melting furnace is a device used to melt aluminum alloy raw materials and scrap aluminum into liquid aluminum. It heats the aluminum material above its melting point through methods such as resistance heating, induction heating, or flame heating, causing it to melt and form molten aluminum.

[0003] An induction furnace is a smelting device that uses the principle of electromagnetic induction to heat metal materials and is widely used in the metal smelting industry. During the production process, due to impurities and oxidation of the metal raw materials, slag will be generated on the surface of the molten pool. In traditional methods, workers use tools such as slag shovels to pick or scoop the slag from the molten pool to clean it.

[0004] The shortcomings of the existing technical solutions are as follows: First, the use of tools such as slag shovels for cleaning is extremely labor-intensive, posing a severe test to the physical strength and endurance of the operators. Second, this method is relatively inefficient, requiring a long time to complete and affecting production progress. Third, manual cleaning carries high safety risks; the high-temperature environment of the molten pool and the potential generation of toxic and harmful gases all threaten the safety of the operators. Summary of the Invention

[0005] The purpose of this utility model is to provide a melting furnace for aluminum ingot production, so as to solve the technical problems of high labor intensity and long time consumption in the prior art of manually cleaning aluminum molten slag.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A melting furnace for aluminum ingot production includes a support frame, the support frame including a U-shaped support frame and an L-shaped support frame fixed behind the U-shaped support frame, an induction furnace for carrying molten aluminum is rotatably connected to the U-shaped support frame, a slag removal mechanism for removing slag is provided on the L-shaped support frame, and a tilting mechanism for tilting the induction furnace to facilitate slag removal is provided on the L-shaped support frame.

[0008] As a further embodiment of this utility model: the scum removal mechanism includes a lifting component disposed on the upper end of an L-shaped support frame, and the output end of the lifting component is provided with a scum collection component and a stirring component.

[0009] As a further embodiment of this utility model: the lifting assembly includes an electric telescopic device fixedly installed on the upper end of the L-shaped support frame, and the scum collection assembly and the stirring assembly are installed at the output end of the electric telescopic device.

[0010] As a further embodiment of this utility model: the stirring assembly includes a second motor fixedly connected to the output end of the electric telescopic device, a first transmission rod fixedly connected to the output end of the second motor, and a stirring plate fixedly connected to the lower end of the first transmission rod.

[0011] As a further embodiment of this utility model: a fixed plate is fixedly installed on the second motor, and the scum collection assembly includes a guide plate for guiding the scum installed below the fixed plate. A second transmission rod is rotatably installed at one end of the fixed plate. A scum cleaning wheel for transporting scum and cooperating with the end of the guide plate is coaxially fixedly connected to the lower end of the second transmission rod. Transmission components for transmission are installed on the first transmission rod and the second transmission rod. A liquid outlet is provided on one side of the induction furnace, and the scum cleaning wheel is located on the side of the liquid outlet.

[0012] As a further embodiment of this utility model: the transmission assembly includes a transmission wheel coaxially fixedly connected to the first transmission rod, and a drive wheel coaxially fixedly connected to the second transmission rod, wherein a transmission belt is provided on the transmission wheel and the drive wheel.

[0013] As a further embodiment of this utility model: the tilting mechanism includes a first motor fixedly mounted on an L-shaped support frame, the output end of the first motor is fixedly connected to a winding disc, a traction cable is wound on the winding disc, and the other end of the traction cable is fixedly connected to the lower end of the induction furnace.

[0014] As a further embodiment of this utility model, the guide plate is arranged in an arc shape.

[0015] As a further embodiment of this utility model: multiple sets of blades for propelling the floating scum are fixedly arranged around the side of the scum cleaning wheel.

[0016] As a further embodiment of this utility model: a connecting plate is fixedly provided on the fixed plate, and a connecting cylinder is fixedly provided on the other end of the connecting plate. The first transmission rod is rotatably sleeved on the inner side of the connecting cylinder, and the guide plate is fixedly connected to the connecting cylinder.

[0017] The beneficial effects of this utility model are:

[0018] 1. In use, when scraping off slag, the electric telescopic device drives the stirring plate into the molten aluminum. The second motor drives the first transmission rod to rotate, which in turn drives the stirring plate to rotate, thereby agitating the molten aluminum. This causes the slag to move on the surface of the molten aluminum and to aggregate under the action of the guide plate. Simultaneously, the agitation accelerates the rapid floating of impurities inside the molten aluminum, forming slag and thus improving cleaning efficiency. When the first transmission rod rotates, it drives the transmission wheel to rotate. The transmission wheel, through a transmission belt, drives the drive wheel to rotate, which in turn drives the second transmission rod to rotate. The second transmission rod then drives the slag-cleaning wheel to rotate, which scrapes the slag accumulated at one end of the guide plate out of the induction furnace, thus achieving automatic slag removal.

[0019] 2. In order to ensure that the slag can be scraped out of the induction furnace when using this utility model, the first motor rotates to drive the winding disc to rotate, and the winding disc drives the traction cable to move, thereby pulling the bottom of the induction furnace, so that the upper part of the induction furnace is slightly tilted towards the liquid outlet, so that the surface of the aluminum liquid is close to the liquid outlet of the induction furnace, thus making it easier to send the slag on the aluminum liquid out of the induction furnace.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

As shown in Figure 1, an induction furnace 2 for carrying molten aluminum is rotatably connected to the U-shaped support frame 101. A slag removal mechanism 4 for removing slag is provided on the L-shaped support frame 102. A tilting mechanism 3 for tilting the induction furnace 2 to facilitate the removal of slag is provided on the L-shaped support frame 102.

[0027] The scum removal mechanism 4 includes a lifting assembly mounted on the upper end of the L-shaped support frame 102. The output end of the lifting assembly is equipped with a scum collection assembly and a stirring assembly. As shown in Figure 2, the lifting assembly includes an electric telescopic device 401 fixedly mounted on the upper end of the L-shaped support frame 102. The stirring assembly includes a second motor 402 fixedly connected to the output end of the electric telescopic device 401. A first transmission rod 405 is fixedly connected to the output end of the second motor 402, and a stirring plate 406 is fixedly connected to the lower end of the first transmission rod 405. The electric telescopic device 401 drives the stirring plate 406 into the molten aluminum. The second motor 402 drives the first transmission rod 405 to rotate, which in turn drives the stirring plate 406 to rotate, thereby achieving stirring of the molten aluminum. A fixing plate 403 is fixedly mounted on the second motor 402. The scum collection assembly includes a guide plate 411 located below the fixing plate 403 for guiding the scum. A second transmission rod 408 is rotatably mounted on one end of the fixing plate 403. A scum-cleaning wheel 409, which cooperates with the end of the guide plate 411, is coaxially fixedly connected to the lower end of the second transmission rod 408. A transmission assembly for transmission is mounted on the first transmission rod 405 and the second transmission rod 408. A liquid outlet 201 is located on one side of the induction furnace 2. The scum-cleaning wheel 409 is located on one side of the liquid outlet 201 to facilitate scraping the scum out of the liquid outlet 201. The transmission assembly includes a transmission wheel 404 coaxially fixedly connected to the first transmission rod 405 and a drive wheel 407 coaxially fixedly connected to the second transmission rod 408. A transmission belt is fitted on the transmission wheel 404 and the drive wheel 407. When the first transmission rod 405 rotates, it drives the transmission wheel 404 to rotate. The transmission wheel 404 drives the drive wheel 407 to rotate via the transmission belt. The drive wheel 407 drives the second transmission rod 408 to rotate. The second transmission rod 408 drives the cleaning wheel 409 to rotate, thereby achieving the cleaning of floating scum.

[0028] In this embodiment, as shown in Figure 2, a connecting plate 412 is fixedly mounted on the fixed plate 403, and a connecting cylinder 410 is fixedly mounted on the other end of the connecting plate 412. The first transmission rod 405 is rotatably sleeved inside the connecting cylinder 410, and the guide plate 411 is fixedly connected to the connecting cylinder 410, thereby fixing the guide plate 411. As shown in Figure 3, the guide plate 411 is arc-shaped, which facilitates the guidance of the scum. Multiple sets of blades for pushing the scum to move are fixedly mounted around the side of the scum cleaning wheel 409, which facilitates the transportation of the scum.

[0029] The tilting mechanism 3 includes a first motor 301 fixedly mounted on an L-shaped support frame 102. A winding disc 302 is fixedly connected to the output end of the first motor 301, and a traction cable 303 is wound around the winding disc 302. The other end of the traction cable 303 is fixedly connected to the lower end of the induction furnace 2. To ensure that slag can be scraped out of the induction furnace 2, when scraping out slag, the first motor 301 rotates, driving the winding disc 302 to rotate. The winding disc 302 drives the traction cable 303 to move, thereby pulling the bottom of the induction furnace 2, causing the upper end of the induction furnace 2 to tilt slightly towards the outlet 201, so that the surface of the molten aluminum is close to the outlet 201 of the induction furnace 2, thus facilitating the removal of slag from the molten aluminum.

[0030] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of the embodiments of this solution will now be explained in conjunction with specific application scenarios:

[0031] In use, in order to ensure that the slag can be scraped out of the induction furnace 2, when scraping out the slag, the first motor 301 rotates and drives the winding disc 302 to rotate. The winding disc 302 drives the traction cable 303 to move, thereby pulling the bottom of the induction furnace 2, so that the upper end of the induction furnace 2 is slightly tilted towards the liquid outlet 201, so that the surface of the aluminum liquid is close to the liquid outlet 201 of the induction furnace 2, thus making it easier to send the slag on the aluminum liquid out of the induction furnace 2.

[0032] The electric telescopic device 401 drives the stirring plate 406 into the molten aluminum. The second motor 402 drives the first transmission rod 405 to rotate, which in turn drives the stirring plate 406 to rotate, thereby agitating the molten aluminum. This causes the scum to move on the surface of the molten aluminum, and during use, the scum can aggregate under the action of the guide plate 411. Simultaneously, the agitation accelerates the rapid buoyancy of impurities (aluminum oxides and non-metallic oxides) within the molten aluminum, forming scum and thus improving cleaning efficiency.

[0033] When the first transmission rod 405 rotates, it drives the transmission wheel 404 to rotate. The transmission wheel 404 drives the drive wheel 407 to rotate via a transmission belt. The drive wheel 407 drives the second transmission rod 408 to rotate, and the second transmission rod 408 drives the slag-cleaning wheel 409 to rotate. After stirring for a period of time, the electric telescopic device 401 slowly brings the slag-cleaning wheel 409 and the guide plate 411 close to the molten aluminum. The guide plate 411 intercepts and guides the slag, and the slag-cleaning wheel 409 scrapes the slag accumulated at one end of the guide plate 411 out of the induction furnace 2.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
