Description

Technical Field

[0001] This utility model relates to the field of aluminum scrap recycling, and in particular, to a device for recycling and utilizing waste aluminum scrap from aluminum wheel manufacturing. Background Technology

[0002] Currently, Chinese patent CN222058449U discloses an aluminum scrap recycling device, which includes a crushing mechanism, a transport mechanism, a frame, and a heating mechanism. The crushing mechanism includes a driving component and a crushing component, and the driving component is driven to connect with the crushing component. One end of the transport mechanism is connected to the crushing component, and the heating mechanism is located below the other end of the transport mechanism. The transport mechanism is connected to the frame.

[0003] By incorporating a crushing mechanism, a conveying mechanism, a frame, and a heating mechanism, aluminum scraps can be placed in the crushing mechanism. The drive unit then pulverizes the aluminum scraps. The pulverized scraps are then transported to the heating mechanism for melting. This process avoids the problem of aluminum sheets and scraps mixing during melting, which would affect the melting efficiency and thus improve the recycling and processing effect of this aluminum scrap recycling equipment.

[0004] Aluminum is easily oxidized at high temperatures to form aluminum oxide, resulting in metal loss. When aluminum shavings are loose, they have a large surface area and are in full contact with air, leading to a more intense oxidation reaction and a low metal recovery rate. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a device for recycling waste aluminum scraps from aluminum wheel processing, so as to improve the aluminum metal recycling rate.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a device for recycling aluminum scrap from aluminum wheel processing, comprising a support frame and a conveying pipe. The conveying pipe is fixed on the support frame, and the side wall of the conveying pipe has an open groove. A rotating shaft is rotatably connected inside the conveying pipe, and a spiral plate is connected to the outer wall of the rotating shaft. The rotating shaft rotates and conducts aluminum scrap to the discharge end of the conveying pipe. A compression pipe connected to the discharge end of the conveying pipe is fixedly connected to the support frame. A feeding groove connected to the outlet end of the compression pipe is opened on the support frame. A slider is slidably connected inside the feeding groove. A compression plane corresponding to the outlet end of the compression pipe is opened on the upper surface of the slider. A pressure rod is slidably connected inside the compression pipe, and the pressure rod slides along the compression pipe toward the slider.

[0007] To achieve the above technical solution, aluminum shavings are placed into the conveying pipe from the open slot. When the rotating shaft rotates, the spiral plate rotates along the axis of the rotating shaft, causing the aluminum shavings to enter the compression pipe from the discharge end of the conveying pipe. Subsequently, the pressure rod moves along the compression pipe. Under the pressure action between the pressure rod, the compression plane, and the inner wall of the compression pipe, the aluminum shavings are compressed into aluminum blocks. At this time, the gaps between the aluminum shavings are reduced, and the overall surface area is significantly reduced, thereby significantly reducing the amount of alumina generated. Then, the slider moves and is misaligned with the pressure rod. The pressure rod moves further down to push the aluminum blocks into the feeding trough. The slider then resets and pushes the aluminum blocks out of the feeding trough. This can improve the aluminum metal recovery rate during aluminum block smelting.

[0008] As a preferred embodiment of this utility model, a power motor is slidably connected to the support frame. The power motor is fixed to the support frame by a positioning bolt. A placement groove is provided on the power rod of the power motor. A connecting groove is provided on the inner wall of the placement groove. A connecting block is fixed on the outer wall of the rotating shaft. When the rotating shaft is inserted into the placement groove, the connecting block is embedded in the connecting groove.

[0009] To achieve the above technical solution, first fix the connecting block to the outer wall of the rotating shaft, then move the power motor closer to the rotating shaft so that the end of the rotating shaft is placed in the placement groove, and at the same time, place the connecting block in the connecting groove. Finally, use the positioning bolt to fix the power motor to the support frame. When the power motor is started, the rotating shaft can rotate, making installation convenient.

[0010] In a preferred embodiment of this utility model, a feed hopper is fixedly connected to the opening groove, the feed hopper is located above the conveying pipe, and the opening area of ​​the upper end of the feed hopper is larger than the opening area of ​​the opening groove.

[0011] To achieve the above technical solution, workers use shovels to shovel aluminum shavings into the feed hopper. Gravity allows the aluminum shavings to enter the conveying pipe along the feed hopper and the open slot, making it easier for workers to load materials.

[0012] As a preferred embodiment of this utility model, a guide plate is hinged to the inner wall of the feed hopper, and an elastic element is connected between the guide plate and the inner wall of the feed hopper.

[0013] To achieve the above technical solution, during the process of shoveling aluminum shavings into the feed hopper, the shovel should be tilted downwards while it is inside the feed hopper so that it contacts the guide plate. At the same time, the aluminum shavings fall onto the guide plate and move down along the guide plate into the conveying pipe. Some of the aluminum shavings will adhere to the guide plate. When the shovel contacts the guide plate, the guide plate vibrates due to the elastic force of the elastic element, which helps to shake the aluminum shavings off the guide plate. This eliminates the need for workers to clean the inner wall of the feed hopper and also improves the protection of the inner wall of the feed hopper.

[0014] In a preferred embodiment of this utility model, a power cylinder is fixedly connected to the support frame, and the hydraulic rod of the power cylinder is fixedly connected to the pressure rod.

[0015] To achieve the above technical solution, the power cylinder is activated, and the hydraulic rod drives the pressure rod to move synchronously, so as to compress the aluminum chips more tightly.

[0016] In a preferred embodiment of this utility model, the support frame is fixedly connected to a feeding cylinder, and the telescopic shaft of the feeding cylinder is connected to the slider.

[0017] To achieve the above technical solution, the feeding cylinder is activated to drive the slider to move, thereby realizing the automatic feeding process and improving production efficiency. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0026] A device for recycling waste aluminum scrap from aluminum wheel manufacturing includes a support frame 1 and a conveying pipe 2. The conveying pipe 2 is fixed to the support frame 1 and is horizontally arranged. An opening groove 3 is provided on the side wall of the conveying pipe 2, with the opening of the opening groove 3 facing upwards. A feed hopper 4 is fixedly connected to the opening groove 3, located above the conveying pipe 2, and the opening area of ​​the upper end of the feed hopper 4 is larger than the opening area of ​​the opening groove 3.

[0027] A guide plate 5 is hinged to the inner wall of the feed hopper 4, and an elastic element 6, which is a spring, is fixed between the guide plate 5 and the inner wall of the feed hopper 4. The worker uses a shovel to scoop up aluminum shavings and place them in the feed hopper 4. Then, the shovel is flipped so that the aluminum shavings fall onto the guide plate 5. The shovel collides with the guide plate 5, and the guide plate 5 vibrates continuously due to the elastic force of the elastic element 6, shaking the aluminum shavings off the guide plate 5 and allowing them to enter the conveying pipe 2 along the opening groove 3. This eliminates the need for workers to clean the guide plate 5, improving production efficiency.

[0028] A rotating shaft 7 is rotatably connected inside the conveying pipe 2, and the rotating shaft 7 is coaxially arranged with the conveying pipe 2. A spiral plate 8 is fixedly connected to the outer wall of the rotating shaft 7. The rotating shaft 7 drives the spiral plate 8 to rotate and conducts aluminum chips to the discharge end of the conveying pipe 2. The outer edge of the spiral plate 8 is close to the inner wall of the conveying pipe 2.

[0029] A power motor 9 is slidably connected to the support frame 1, close to the conveying pipe 2, and fixed to the support frame 1 by a positioning bolt 10. A placement groove 12 is provided on the power rod 11 of the power motor 9, and the placement groove 12 is coaxially arranged with the power rod 11. A connecting groove 13 is provided on the inner wall of the placement groove 12, and the cross-section of the connecting groove 13 is square. A connecting block 14 is fixed on the outer wall of the rotating shaft 7, and when the rotating shaft 7 passes into the placement groove 12, the connecting block 14 is embedded in the connecting groove 13.

[0030] Therefore, when the power motor 9 starts, the power rod 11 can drive the rotating shaft 7 to rotate.

[0031] A compression pipe 15, which communicates with the discharge end of the conveying pipe 2, is fixedly connected to the support frame 1. The compression pipe 15 is placed vertically. The side wall of the compression pipe 15 is connected to the conveying pipe 2. A pressure rod 16 is slidably connected inside the compression pipe 15.

[0032] A discharge trough 17 is provided on the support frame 1, which is connected to the outlet end of the compression pipe 15. The discharge trough 17 is located below the compression pipe 15.

[0033] A slider 18 is slidably connected within the feeding trough 17. A compression plane 19, corresponding to the outlet end of the compression tube 15, is formed on the upper surface of the slider 18. A vertically mounted power cylinder 20 is fixedly connected to the support frame 1. The hydraulic rod 21 of the power cylinder 20 is fixedly connected to the pressure rod 16, and the hydraulic rod 21 and the pressure rod 16 are coaxially arranged. The power cylinder 20 is a hydraulic cylinder.

[0034] When the power cylinder 20 is started, the pressure rod 16 slides along the compression tube 15 toward the slider 18.

[0035] A horizontally positioned feeding cylinder 22 is fixedly connected to the support frame 1, and the telescopic shaft 23 of the feeding cylinder 22 is fixedly connected to the slider 18. The feeding cylinder 22 is also a hydraulic cylinder.

[0036] In operation, aluminum shavings are first shoveled into the feed hopper 4. The shavings then enter the conveying pipe 2. The power motor 9 starts, the rotating shaft 7 rotates, and the spiral plate 8 rotates along the axis of the rotating shaft 7, causing the aluminum shavings to be transported along the conveying pipe 2 to the compression pipe 15. At this time, the power cylinder 20 starts, and the pressure rod 16 moves downward. Under the action of the pressure rod 16, the compression pipe 15, and the slider 18, the aluminum shavings are compressed and compacted within the compression pipe 15 to obtain aluminum blocks. Then, the feeding cylinder 22 is opened, and the telescopic shaft 23 retracts, causing the slider 18 to misalign with the pressure rod 16. The power cylinder 20 then starts again, and the pressure rod 16 moves further downward, pushing the aluminum blocks from the compression pipe 15 into the feeding trough 17. Then, the feeding cylinder 22 is opened again, causing the telescopic shaft 23 to extend, allowing the slider 18 to push the aluminum blocks out of the feeding trough 17 for easy collection by workers. This achieves a fully automatic process of compressing aluminum shavings to obtain aluminum blocks. The reduced gaps between aluminum chips within the aluminum block significantly decrease the overall surface area, thereby substantially reducing the amount of alumina generated.

[0037] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
