Description

Technical Field

[0001] This invention relates to the field of aluminum smelting technology, and more specifically to an aluminum smelting alumina recovery device. Background Technology

[0002] During the aluminum smelting process, aluminum oxide, as a common impurity, is mixed into the molten aluminum. The presence of aluminum oxide not only reduces the quality of aluminum products, affecting their mechanical properties and corrosion resistance, but also increases the difficulty of subsequent processing. For example, it may cause defects such as porosity and sand holes in the castings during the casting process.

[0003] According to the search, Chinese Patent Announcement No. CN213835494U discloses an aluminum smelting alumina recovery device, which includes a rotating structure and a smelting furnace structure. The finished aluminum liquid enters the heat preservation furnace through the inlet. When the liquid level reaches a certain height, the die casting machine return material is put into the inlet. The high-temperature aluminum liquid rotating in the inlet melts it, and the aluminum liquid and other impurities flow to the slag rake chamber through the bottom trough.

[0004] In the above scheme, molten aluminum and other impurities flow to the slag-raking chamber through the bottom trough. Since the density of aluminum slag is lower than that of molten aluminum, the aluminum slag floats on the surface of the molten aluminum in the slag-raking chamber under the action of buoyancy. When the set slag-cleaning time is reached, the aluminum slag on the surface of the molten aluminum is promptly cleaned out of the holding furnace through the slag-raking port. However, in actual use, it has been found that alumina impurities will inevitably mix into the molten aluminum during the aluminum smelting process. Since the device is not equipped with a special impurity removal device, it is impossible to effectively separate alumina impurities. The presence of alumina will reduce the purity of the molten aluminum. In addition, the device does not have a special alumina recovery device, and the alumina impurities separated from the molten aluminum cannot be effectively recovered and utilized. Therefore, it is necessary to design an aluminum smelting alumina recovery device. Summary of the Invention

A drive motor is fixedly installed at the rear end of the frame and at the top of the rear end of the smelting chamber. The output end of the drive motor passes through the rear end of the frame and is fixedly connected to a lead screw.

The adjusting blocks are fixedly connected to the scraper via connecting frames. The opposite side of the connecting frames is slidably connected to the front and rear ends of the baffle. The adjusting blocks correspond to the positions of the first and second trapezoidal adjusting blocks. The adjusting blocks have inclined surfaces on both sides that slide in cooperation with the first and second trapezoidal adjusting blocks. When the adjusting block contacts the first trapezoidal adjusting block, it pushes the adjusting block upward. When the adjusting block contacts the second trapezoidal adjusting block, it pushes the adjusting block downward. A recycling component is provided in the middle of the side of the smelting box near the impurity removal component.

[0008] Preferably, a first magnetic block is fixedly installed at the top of the U-shaped block, a second magnetic block is fixedly installed at the top of the scraper inside the U-shaped block, and two third magnetic blocks are fixedly installed at the bottom of the U-shaped block.

[0011] Preferably, the outer surface of the stirring shaft is provided with a plurality of raised textures, which are arranged along the length direction of the stirring shaft.

[0012] Preferably, the recycling component includes a valve fixedly installed at the center of one side of the smelting tank, a drain pipe fixedly connected to one side of the valve, and a dovetail groove opened around the roller in the aluminum liquid recycling tank below the drain pipe.

It can more accurately scrape the alumina impurities to the impurity removal port and collect them in the impurity recovery tank. The impurity removal effect is better and more controllable. In addition, a partition baffle is set to divide the melting box into a stirring area and an impurity removal area. The stirring component accelerates the aluminum dissolution in the stirring area, so that the alumina impurities are better separated. Then the aluminum liquid flows into the impurity removal area through the through hole in the middle of the partition baffle. This area division and collaborative work makes the impurity removal process more orderly, avoids the secondary mixing of impurities in the melting process, and further improves the impurity removal effect.

[0017] (2) This device not only collects aluminum liquid in the impurity recovery tank, but also performs secondary filtration and purification in the aluminum liquid recovery tank, realizing multi-stage recovery. The high-purity aluminum liquid recovered can be re-entered into the smelting process for dissolution, realizing the recycling of aluminum liquid, greatly improving the utilization rate of aluminum resources, reducing resource waste, and fully recovering aluminum liquid reduces the enterprise's purchase of new aluminum raw materials and lowers production costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4This utility model discloses an aluminum smelting and alumina recovery device, including a smelting box 1. A partition baffle 207 is provided inside the smelting box 1, forming a stirring zone and a purification zone within the smelting box 1. A stirring assembly 2 is provided inside the stirring zone to accelerate aluminum dissolution. A purification assembly 3 is provided at the top of the purification zone. The purification assembly 3 includes a frame 302 fixedly installed on one side of the top of the smelting box 1. A drive motor 301 is fixedly installed at the rear end of the frame 302 and at the top of the rear end of the smelting box 1. The output end of the drive motor 301 passes through the rear end of the frame 302 and is fixedly connected to a lead screw 303. One end of the lead screw 303 is rotatably connected to the front end inside the frame 302. 02 An internal sliding connection is provided with a baffle 304. A lead screw 303 is threadedly connected to the center of the baffle 304. Two first trapezoidal adjusting blocks 306 and two second trapezoidal adjusting blocks 307 are fixedly installed at the front and rear ends of the top of the frame 302, respectively. A U-shaped block 308 is fixedly connected to the bottom of the baffle 304. A scraper 310 is provided below the U-shaped block 308. A matching adjusting block 314 is provided on the upper part of both sides of the top of the baffle 304. The matching adjusting block 314 is fixedly connected to the scraper 310 through a connecting bracket 313. The opposite side of the connecting bracket 313 is slidably connected to the front and rear ends of the baffle 304. The matching adjusting block 314 corresponds to the first trapezoidal adjusting block 306 and the second trapezoidal adjusting block 307. Both sides are provided with inclined surfaces that slide in conjunction with the first trapezoidal adjusting block 306 and the second trapezoidal adjusting block 307. When the adjusting block 314 contacts the first trapezoidal adjusting block 306, it pushes the adjusting block 314 upward; when the adjusting block 314 contacts the second trapezoidal adjusting block 307, it pushes the adjusting block 314 downward. A recycling component 4 is provided in the middle of the side of the melting box 1 near the impurity removal component 3. Inside the melting box 1, the partition baffle 207 divides it into a stirring zone and an impurity removal zone. After the stirring component 2 in the stirring zone is activated, it accelerates the melting of aluminum. In the impurity removal component 3 in the impurity removal zone, the drive motor 301 drives the lead screw 303 to rotate. Because the lead screw is threadedly connected to the baffle 304, it promotes... The baffle slides within the frame 302. During the sliding process, the adjusting blocks 314 on both sides of the top of the baffle contact the first trapezoidal adjusting blocks 306 and the second trapezoidal adjusting blocks 307 at the front and rear ends of the top of the frame. By using the inclined surface, the adjusting blocks 314 move up and down, which drives the scraper 310 to move up and down through the connecting frame 313, thereby scraping off impurities on the surface of the molten aluminum. The treated molten aluminum is then recycled through the recycling component 4. The effect is that through the partitioned design and the coordinated work of each component, the aluminum dissolution process is accelerated, the smelting efficiency is improved, impurities on the surface of the molten aluminum are effectively removed, the purity of the molten aluminum is improved, and the molten aluminum is successfully recycled, ensuring the high efficiency and stability of the entire aluminum smelting and alumina recycling process.

[0026] As one implementation method of this embodiment, such as Figure 3As shown, a first magnetic block 309 is fixedly installed at the top of the U-shaped block 308. The top of the scraper 310 is located inside the U-shaped block 308 and a second magnetic block 311 is fixedly installed thereon. Two third magnetic blocks 312 are fixedly installed at the bottom of the U-shaped block 308. The second magnetic block 311 has opposite magnetic poles to the first magnetic block 309 and the third magnetic block 312 and they attract each other. The first magnetic block 309 at the top of the U-shaped block 308 and the two third magnetic blocks 312 at the bottom attract each other to the second magnetic block 311 at the top of the scraper 310 because of their opposite magnetic poles. This magnetic attraction makes the scraper 310 firmly connected to the bottom of the U-shaped block 308. Its effect is to ensure that the scraper 310 and the U-shaped block 308 are stably connected during the operation of the impurity removal component, so that the scraper can stably perform the task of scraping impurities on the surface of the aluminum liquid, avoiding the impact of loosening and other problems on the impurity removal effect, and improving the reliability and stability of the impurity removal component.

[0027] As one implementation method of this embodiment, such as Figure 1 As shown, a cleaning port is opened at the bottom front end of the frame 302 and at the top front end of the melting box 1. An impurity recovery tank 305 is fixedly installed at the front end of the melting box 1 and at the cleaning port. When the cleaning component is running, the scraper 310 scrapes the impurities on the surface of the molten aluminum to the bottom front end of the frame 302. Since the cleaning port is set here, the impurities fall through the cleaning port under the action of gravity and fall into the impurity recovery tank 305 located at the cleaning port. The effect is that the cleaning port and the impurity recovery tank provide a clear collection path and storage space for the impurities, realize the automatic collection and cleaning of impurities, reduce the workload of manual cleaning, and at the same time avoid the accumulation of impurities in the melting box, which affects the quality of the molten aluminum and the operation of the equipment, thus ensuring the efficiency and cleanliness of the aluminum smelting process.

[0028] As one implementation method of this embodiment, such as Figure 2As shown, the stirring assembly 2 includes a top plate 201 fixedly installed at the middle of the top of the melting box 1. A rotary motor 202 is fixedly installed at the center of the top of the top plate 201. A roller 203 is fixedly connected to the output end of the rotary motor 202 through the top plate 201. A rotating disk 204 is fixedly connected to the bottom of the roller 203. Multiple grooves are formed at the bottom of the rotating disk 204. A stirring shaft 205 is vertically arranged at each groove. The top end of the stirring shaft 205 is slidably connected to the groove. A spring 206 is fixedly connected between the side of the stirring shaft 205 away from the center of the rotating disk 204 and the inner wall of the groove. After the rotary motor 202 on the top plate 201 is started, Its output end drives the roller 203 to rotate, which in turn causes the rotating disk 204 connected to the bottom of the roller to rotate. When the rotating disk rotates, the stirring shaft 205 located in the groove at the bottom and slidably connected to it at the top rotates accordingly. At the same time, the spring 206 between the side of the stirring shaft away from the center of the rotating disk and the inner wall of the groove will extend and retract due to centrifugal force and other factors during the rotation of the stirring shaft, so that the stirring shaft can slide in the groove while rotating. The effect is that this combination of rotation and sliding motion expands the stirring range of the stirring shaft, enhances the stirring force and uniformity, accelerates the melting process of aluminum in the melting box, and improves the efficiency and quality of aluminum melting.

[0029] As one implementation method of this embodiment, such as Figure 2 As shown, the outer surface of the stirring shaft 205 is provided with multiple raised textures. The raised textures are arranged along the length direction of the stirring shaft 205. During the rotation of the stirring shaft 205 to stir the aluminum liquid, the raised textures arranged along its length direction increase the contact area and surface roughness between the stirring shaft and the aluminum liquid, so that the aluminum liquid is subjected to more resistance and disturbance when flowing. The effect is that the raised textures can enhance the stirring effect of the stirring shaft on the aluminum liquid, promote more thorough mixing of the aluminum liquid, accelerate heat transfer, and thus effectively accelerate the aluminum dissolution process, improve aluminum smelting efficiency, and at the same time improve the uniformity of aluminum liquid mixing and ensure smelting quality.

[0030] As one implementation method of this embodiment, such as Figure 2 As shown, the recycling component 4 includes a valve 401 fixedly installed at the center of one side of the smelting tank 1. A drain pipe 402 is fixedly connected to one side of the valve 401. An aluminum liquid recycling tank 403 is set below the drain pipe 402. After the aluminum liquid is stirred and impurities are removed in the smelting tank 1, the valve 401 is opened. Under its own gravity, the aluminum liquid flows out of the smelting tank 1 through the drain pipe 402 and flows into the aluminum liquid recycling tank 403 below. The effect is that the recycling component controls the outflow of aluminum liquid through the valve and realizes the directional transportation of aluminum liquid through the drain pipe, so as to safely and conveniently recycle the aluminum liquid into the aluminum liquid recycling tank, reduce the loss and leakage during the transfer of aluminum liquid, improve the efficiency and safety of aluminum liquid recycling, and facilitate the subsequent storage and processing of aluminum liquid.

[0031] As one implementation method of this embodiment, such as Figure 2 As shown, the aluminum liquid recovery tank 403 is equipped with a filter layer located below the inlet pipe 402. The aluminum liquid flowing into the aluminum liquid recovery tank 403 through the inlet pipe 402 falls naturally under the action of gravity and passes directly through the filter layer located below the inlet pipe. The filter layer intercepts residual impurity particles in the aluminum liquid, allowing only pure aluminum liquid to pass through and be stored in the tank. Its effect is that by setting up the filter layer, it can further remove any impurities that may remain in the aluminum liquid, effectively improve the purity of the aluminum liquid, reduce the adverse effects of impurities on subsequent aluminum processing stages, improve the quality of the final aluminum products, and at the same time reduce the risk of equipment wear and failure caused by impurities.

[0032] As one implementation method of this embodiment, such as Figure 2 As shown, the partition baffle 207 is fixedly connected to the bottom of the interior of the smelting tank 1 and the bottom of the top plate 201, respectively. A through hole is opened in the middle of the partition baffle 207, through which the molten aluminum flows smoothly from the stirring area into the impurity removal area. The height of the through hole is higher than the height of the valve 401. The partition baffle 207 is fixedly connected to the bottom of the interior of the smelting tank 1 and the bottom of the top plate 201, dividing the smelting tank into a stirring area and an impurity removal area. The through hole in the middle serves as a connecting channel. During the aluminum smelting process, after the molten aluminum in the stirring area reaches a certain liquid level, it flows into the impurity removal area through the through hole by gravity. Since the height of the through hole is higher than that of the valve 401, it can be ensured that the molten aluminum completes the impurity removal process first, and then is discharged through the valve and the recovery component. The effect is that the setting of the partition baffle and the through hole realizes the functional zoning of stirring and impurity removal, ensures that the molten aluminum is processed in an orderly manner according to the established process, and avoids the molten aluminum without impurity removal directly entering the recovery stage. The reasonable design of the through hole height ensures that the impurity removal process is fully carried out, improves the purity of the molten aluminum and the quality of recovery, and optimizes the aluminum smelting alumina recovery process.

[0033] Working principle: When the device is running, the rotary motor 202 in the stirring area is powered on and started. Its output end drives the roller 203 to rotate, which in turn drives the rotating disk 204 connected to the roller to rotate. Under the dual action of centrifugal force and spring 206, the stirring shaft 205 in the groove at the bottom of the rotating disk 204 not only rotates with the rotating disk, but can also slide and extend within the groove. The raised texture on the outside of the stirring shaft 205 increases the contact area and friction with the aluminum liquid, thereby efficiently stirring the aluminum liquid and accelerating the aluminum dissolution process.

[0034] In the impurity removal area, the drive motor 301 drives the lead screw 303 to rotate. Since the lead screw 303 is threadedly connected to the baffle 304, the rotation of the lead screw is converted into the horizontal sliding of the baffle 304 within the frame 302. As the baffle 304 moves, the mating adjustment block 314 at its top contacts the first trapezoidal adjustment block 306 and the second trapezoidal adjustment block 307 at the top of the frame 302. The inclined surfaces on both sides of the mating adjustment block 314 engage with the trapezoidal adjustment blocks, causing it to undulate up and down during horizontal movement. The mating adjustment block 314 drives the scraper 310 to move synchronously through the connecting frame 313. The scraper 310 is below the U-shaped block 308 and is kept stable by the magnetic attraction of the first magnetic block 309, the second magnetic block 311, and the third magnetic block 312 inside, thus achieving the removal of impurities from the surface of the molten aluminum. The removed impurities fall into the impurity recovery tank 305 through the impurity removal port at the bottom front end of the frame 302.

[0035] After stirring and impurity removal, the molten aluminum flows from the stirring area into the impurity removal area through the through hole in the middle of the baffle 207 under the action of gravity. When it is necessary to recover the molten aluminum, the valve 401 in the recovery component 4 is opened. Under the action of gravity, the molten aluminum flows into the aluminum recovery tank 403 below through the diversion pipe 402. The filter layer in the aluminum recovery tank 403 performs secondary filtration on the incoming molten aluminum to intercept residual impurities and ensure the high purity of the recovered molten aluminum, thus completing the entire aluminum smelting alumina recovery process.

[0036] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
