Description

Technical Field

[0001] This utility model relates to the technical field of waste aluminum ingot recycling equipment, and in particular to an aluminum ingot recycling and reuse device. Background Technology

[0002] Aluminum ingots, as a commonly used industrial raw material, generate a large amount of scrap and waste aluminum ingots during processing. These need to be melted and recycled to produce usable molten aluminum or new aluminum ingots. Current aluminum ingot recycling methods only involve melting in a crucible, with the molten aluminum being poured directly without a filtration system. This means that residual oxide slag and metallic impurities in the molten aluminum cannot be removed, failing to meet the requirements of high-precision processing. Furthermore, manual prying or simple mechanical turning is used, making it difficult to control the turning angle and easily leading to spillage of high-temperature molten aluminum. Manual operation is also physically demanding and poses a risk of burns. In addition, there is no stirring mechanism when the aluminum ingots are melting in the crucible, which easily leads to localized overheating and unmelted areas. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an aluminum ingot recycling and reuse device, which removes large particles such as oxide slag and metal impurities through a filter plate, greatly improving the purity of recycled aluminum and meeting the processing requirements of precision aluminum parts. Moreover, the filter plate is replaceable and has low maintenance costs. The filter plate is equipped with a top plate and two baffles around its perimeter, which can make pure aluminum liquid exit from the nozzle as much as possible and reduce the overflow of pure aluminum liquid.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an aluminum ingot recycling and reuse device is provided, including a base and a crucible. Two columns are arranged side by side on the upper end of the base. The upper ends of the two columns are respectively connected to the two sides of the front end of the crucible by hinges. A hydraulic cylinder for controlling the crucible to rotate is installed on the upper end of the base. A spout extending outward and raised is provided at the middle of the front end of the upper port of the crucible. A baffle is installed on each side of the spout on the upper end of the crucible. A top plate is installed between the two baffles. A filter plate extending into the spout is provided at the lower end of the top plate. A stirring shaft is rotatably installed inside the crucible. A motor for driving the stirring shaft to rotate is installed on the side of the crucible.

[0005] As a supplement to the technical solution described in this utility model, a caster is installed at each of the four corners of the bottom of the base. The caster is a universal wheel with a brake.

[0006] As a supplement to the technical solution described in this utility model, a handle is installed in the middle of the upper end of the top plate.

[0007] As a supplement to the technical solution described in this utility model, a rotating seat is installed at the upper end of the base on the right side of the crucible. The rotating seat is rotatably connected to the bottom of the hydraulic cylinder. A connecting bracket is installed on the right side wall of the crucible. The connecting bracket is rotatably connected to the piston rod at the upper end of the hydraulic cylinder.

[0008] As a supplement to the technical solution described in this utility model, a blocking box is installed on the side of the upper end of the crucible above the hydraulic cylinder. The blocking box is sealed on all sides except for the side closest to the crucible.

[0009] Beneficial effects: This utility model relates to an aluminum ingot recycling and reuse device. It removes large particles such as oxide slag and metallic impurities through a filter plate, significantly improving the purity of recycled aluminum and meeting the processing requirements of precision aluminum parts. Furthermore, the filter plate is replaceable, resulting in low maintenance costs. A top plate and two baffles around the filter plate ensure that pure aluminum liquid exits through the pouring nozzle as much as possible, reducing spillage. A spiral stirring shaft drives the aluminum liquid to tumble up and down, increasing the recovery rate. Hydraulic tilting replaces manual labor, reducing aluminum liquid spillage. The design of the baffle box reduces the risk of burns to operators. Casters allow the entire device to be easily moved to the aluminum ingot stacking point, making operation convenient.

[0014] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0015] The embodiments of this utility model relate to an aluminum ingot recycling and reuse device, such as... Figs. 1-3As shown, the crucible includes a base 1 and a crucible 3. Two columns 4 are arranged side by side on the upper end of the base 1. The upper ends of the two columns 4 are connected to the two sides of the front end of the crucible 3 by hinges 5. A hydraulic cylinder 16 for controlling the rotation of the crucible 3 is installed on the upper end of the base 1. A spout 6 extending outward and raised is provided at the middle of the front end of the upper port of the crucible 3. A baffle 7 is installed on each side of the spout 6 on the upper end of the crucible 3. A top plate 9 is installed between the two baffles 7. A filter plate 8 extending into the spout 6 is provided at the lower end of the top plate 9. A stirring shaft 12 is rotatably installed inside the crucible 3. A motor 11 for driving the stirring shaft 12 is installed on the side of the crucible 3.

[0016] The stirring shaft 12 is made of 310S heat-resistant stainless steel, and its lower end penetrates the bottom of the crucible 3. A high-temperature resistant graphite sealing ring is installed at the contact point between the stirring shaft 12 and the crucible 3 to prevent the aluminum liquid from leaking out of the gap. The spiral stirring blades of the stirring shaft 12 have a large gap with the inner wall of the crucible 3 to avoid scraping the inner wall of the crucible 3 during stirring.

[0017] A caster 2 is installed at each of the four corners of the bottom of the base 1. The caster 2 is a universal caster with brakes; the load-bearing capacity of a single caster is ≥150kg.

[0018] A handle 10 is installed in the middle of the upper end of the top plate 9, which facilitates the taking and putting away of the top plate 9.

[0019] A rotating seat 13 is installed on the upper end of the base 1 on the right side of the crucible 3. The rotating seat 13 is rotatably connected to the bottom of the hydraulic cylinder 16. A connecting bracket 14 is installed on the right side wall of the crucible 3. The connecting bracket 14 is rotatably connected to the piston rod at the upper end of the hydraulic cylinder 16.

[0020] A baffle box 15 is installed on the upper side of the crucible 3 above the hydraulic cylinder 16. The baffle box 15 is sealed on all sides except for the side closest to the crucible 3. The function of the baffle box 15 is to block the splashing aluminum droplets during melting and avoid damaging the hydraulic cylinder seals.

[0021] A control box 17 is installed on the upper end of the base 1. The control box 17 is used to control the operation of the hydraulic cylinder 16 and the motor 11. The control box 17 is equipped with a control switch.

[0022] The operation steps of this utility model are as follows:

[0023] Step 1: Release the brake on caster 2, push the device to the high-temperature furnace for melting scrap aluminum ingots, with the upper end of crucible 3 facing the outlet of the high-temperature furnace, lock the brake on caster 2 to ensure that the device does not move and that the device is located next to the precast aluminum ingot mold.

[0024] Step 2: Add scrap aluminum ingots or offcuts to the high-temperature furnace. Pour the molten scrap aluminum ingots from the high-temperature furnace into crucible 3. Start motor 11. Motor 11 controls the stirring shaft 12 to rotate. The stirring shaft 12 rotates at low speed to stir the molten scrap aluminum ingots thoroughly, improving the aluminum recovery rate. Then turn off motor 11 and the stirring shaft 12 stops rotating. Let the molten scrap aluminum ingots stand for a few minutes. The molten scrap aluminum ingots inside crucible 3 will separate into upper and lower layers. The upper layer is pure aluminum liquid, which is bright silver and free of solid particles. The lower layer is the impurity layer (i.e., aluminum ash).

[0025] Step 3: Hydraulic Tilting and Directional Casting; Start the hydraulic cylinder 16, the piston rod of the hydraulic cylinder 16 slowly extends to push the crucible 3 to rotate around the hinge 5; the pure aluminum liquid on the upper layer of the crucible 3 flows into the nozzle 6 under the action of gravity, and is filtered by the filter plate 8 (large particles of impurities remain on the filter plate 8). The filter plate 8 is equipped with a top plate 9 and two baffles 7 around it, which can make the pure aluminum liquid exit from the nozzle 6 as much as possible and reduce the overflow of pure aluminum liquid. The pure aluminum liquid flows directionally from the end of the nozzle 6 into the aluminum ingot mold below until different colored impurity layers are seen, then stop pouring into the aluminum ingot mold. The hydraulic cylinder 16 remains unchanged. Then the aluminum ingot mold is removed, and then the waste bucket is moved to the bottom of the nozzle 6. The piston rod of the hydraulic cylinder 16 continues to extend to pour the impurity layer in the crucible 3 into the waste bucket;

[0026] Step 4: Reset the device and slowly retract the piston rod of the hydraulic cylinder 16 to reset the crucible 3 to a horizontal position; clean the impurities on the filter plate 8 with a special scraper; after the crucible 3 cools to room temperature, clean the small amount of aluminum dross remaining in the crucible 3 to prepare for the next recycling.

[0027] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
