Description

Technical Field

[0001] This invention relates to the field of waste aluminum recycling technology, and in particular to a waste aluminum recycling and smelting device with multi-stage crushing and eddy current separation. Background Technology

[0002] Waste aluminum recycling and smelting is an important part of the aluminum processing industry. By recycling aluminum waste and re-smelting it, resources can be effectively saved, energy consumption reduced, and environmental pollution reduced. The main steps of waste aluminum recycling and smelting include: crushing, cleaning and pretreatment, and smelting. Since waste aluminum contains oil, coatings, and impurities, cleaning is necessary in the initial stage of smelting. Subsequently, the waste is transported and sorted to separate other impurities from the waste aluminum. Existing technologies have many smelting devices capable of completing these processes, but they also have some shortcomings. During sorting, eddy current separators are generally used. The repulsive force generated by the eddy current separator causes the waste aluminum to bounce and be collected into the target container. However, due to the differences in waste structure and the accumulation and transport of waste, many pieces of waste may collide in the air during sorting, thus changing their bounce direction or even failing to reach the collection container. Furthermore, during continuous processing, excess waste cannot be properly collected and needs to be compressed into blocks for storage. Existing technologies do not offer effective solutions for this. Therefore, this invention proposes a recycling smelting device that integrates multi-stage crushing, eddy current sorting, and compression collection into one unit for effective recycling of waste aluminum.

[0007] As a preferred embodiment, the cleaning mechanism includes an angle motor and a cleaning transmission box fixedly mounted on the side of the lower crushing chamber.

[0008] As a preferred embodiment, the bottom of the screening frame is slidably mounted on the angle frame, and a spring for providing elastic force is connected between the screening frame and the angle frame. A push cylinder is fixedly mounted at one end of the angle frame for pushing the screening frame.

Furthermore, during cleaning, the angle rack and the screening rack are in a horizontal state, and the fixed electric cylinder telescopic rod cooperates with the fixed hole to fix the angle rack; (2) When the scraps are transported, the partition divides the transport area into multiple transport channels, so that the scraps avoid collisions during the leap.

(3) When sorting the scrap, the present invention has two operating methods: the first is to directly transport and smelt, and the second is to compress and collect the excess scrap. (4) When compressing the scrap, the holes on the compression plate are matched with the shaping shaft, so that the middle area of ​​the compressed scrap block has holes, which can facilitate the surface and interior of the compressed block to better contact with the external air, increase air circulation, help the evaporation of moisture, and facilitate stacking and storage. In addition, during subsequent smelting, the surface area of ​​the scrap compressed block increases, which can make the heat more evenly transferred to each part. During the smelting process, the circulation of hot air can be accelerated, making the heating of the scrap compressed block more uniform, thereby reducing the smelting time.

[0019] The sorting mechanism includes a transmission motor 24 fixedly mounted on the side of the transmission frame 5, which drives the transmission belt 25; the eddy current sorting mechanism includes an eddy current separator 28 rotatably mounted inside the transmission roller 27, and a separator motor 30 is provided at one end of the transmission roller 27 to drive the eddy current separator 28 to rotate; an arc-shaped guide plate 34 is provided at one end of the transmission frame 5, and a waste collection box 8 for collecting debris is provided below the arc-shaped guide plate 34; one end of the partition plate 26 extends onto the arc-shaped guide plate 34 in the waste conveying direction.

[0020] The compression mechanism includes a compression cylinder 31 fixedly mounted on the top of the baffle 6, a compression frame 32 fixedly mounted on the telescopic rod of the compression cylinder 31, the compression frame 32 being fixedly connected to the compression plate 33, a position cylinder 39 fixedly mounted on the side of the baffle 6, a position seat 40 fixedly mounted on the telescopic rod of the position cylinder 39, a position cylinder 35 fixedly mounted on the position seat 40, and a position cylinder 36 fixedly mounted on the telescopic rod of the position cylinder 39 being fixedly connected to the compression box 7; a lifting cylinder 36 fixedly mounted on the side of the compression box 7, a support plate 38 fixedly mounted on the telescopic rod of the lifting cylinder 36, the support plate 38 being located at the bottom of the compression box 7 and slidingly engaging with the bottom of the compression box 7, for pushing the waste material compression block.

[0021] Operating principle: Waste aluminum is fed into the top of the crushing box 1. The crushing motor 9 drives the crushing roller 11 to rotate, so as to crush the waste aluminum in multiple stages. Then it falls onto the screening frame 18. The cleaning fluid is transmitted to the nozzle 16 through the cleaning transfer box 14, which pushes the electric cylinder 21 to push the screening frame 18. The screening frame 18 moves back and forth to clean the crushed material. The crushed material remains in the screening frame 18, and the cleaning waste liquid and other impurities fall into the cleaning collection box 3 below. Furthermore, during cleaning, the angle frame 17 and the screening frame 18 are in a horizontal state. The extension rod of the fixed electric cylinder 15 cooperates with the fixing hole 23 to fix the angle frame 17.

[0022] Subsequently, during the transfer of crushed material, the fixed electric cylinder 15 releases the fixing state of the angle frame 17, and the angle motor 13 controls the rotation of the angle frame 17, that is, the screening frame 18 deflects, and the port of the screening frame 18 faces the end of the guide plate 4. The baffle motor 20 controls the deflection of the baffle 19 to release the crushed material. The crushed material falls from the screening frame 18 and is transferred to the conveyor belt 25. The conveyor motor 24 drives the conveyor belt 25 to transport the crushed material. During the transport, the partition 26 divides the transport area into multiple transport channels, so that the crushed material avoids collision with each other during the leap. This helps to maintain the movement trajectory of each piece of waste, thereby ensuring that the sorting process is more accurate and efficient. It can also ensure that the crushed material is evenly distributed, avoids congestion, and makes the flow of crushed material smoother. This can improve the overall production efficiency and avoid jamming or stagnation.

[0023] In the sorting area, the sorter motor 30 drives the eddy current separator 28 to rotate, generating an alternating magnetic field through rotation to produce a repulsive force and sort the scrap aluminum. Other impurities fall into the waste collection box 8 for collection. The scrap aluminum jumps under the action of the repulsive force. In this process, there are two operation steps: Specifically, during the smelting process, the position cylinder 39 controls the position seat 40 to move, so that the compression box 7 is misaligned with the smelting conveyor belt 41 below. The jumping scrap falls onto the smelting conveyor belt 41 for transport and finally enters the smelting container 42 for smelting. During the compression process of excess scrap, the compression box 7 is positioned above the smelting conveyor belt 41. The jumping scrap falls into the compression tank in the compression box 7. Each transmission channel corresponds to a compression tank. When the amount of crushed material in the compression tank reaches the preset amount, the compression frame 32 is moved by the compression cylinder 31, that is, the compression plate 33 descends and cooperates with the compression tank to compress the crushed material. Specifically, the holes on the compression plate 33 cooperate with the shaping shaft 37, so that the middle area of ​​the compressed crushed block has holes, which can facilitate better contact between the surface and the inside of the compressed block and the outside air, increase air circulation, help moisture evaporation, and facilitate stacking and storage. In addition, during subsequent smelting, the surface area of ​​the crushed block increases, which can make the heat more evenly transferred to each part. During the smelting process, it can accelerate the circulation of hot air, make the heating of the crushed block more uniform, and thus reduce the smelting time.

[0024] Furthermore, the height of the compression box 7 is controlled by the position cylinder 35, and the lifting cylinder 36 controls the movement of the support plate 38. The support plate 38 can push the crushed material compression block to facilitate removal.
