Description
Technical Field
[0001] The utility model belongs to the technical field of recycled aluminum manufacturing, and relates to a feeding device for a recycled aluminum melting furnace. Background Technique
[0002] Recycled aluminum is aluminum alloy or aluminum metal obtained by remelting and refining waste aluminum, waste aluminum alloy materials or aluminum-containing waste materials. It is an important source of metallic aluminum. Recycled aluminum mainly appears in the form of aluminum alloy. Due to its many advantages such as short process and low energy consumption, it has good ecological and social benefits.
[0003] The recycled aluminum materials need to be melted. Generally, the melting furnace is large in volume and high in feeding port. Aluminum materials need to be added through a feeding device. After melting, the melting furnace is tilted, and the molten aluminum is poured out from the feeding port. At this time, the feeding device needs to be removed. During production, the feeding device moves repeatedly, which is inconvenient to use.
[0004] Based on this, we designed a feeding device for a recycled aluminum melting furnace. Content of the Utility Model
[0005] The purpose of the utility model is to address the above problems in the existing technology and propose a feeding device for a recycled aluminum melting furnace. The technical problem to be solved by this device is: how to achieve automatic feeding of the recycled aluminum melting furnace without blocking the feeding port.
[0006] The purpose of the utility model can be achieved by the following technical solutions:
[0007] A feeding device for a recycled aluminum melting furnace includes a fixed base and a material box with an open upper end. A vertical cylinder is fixed on the fixed base. The vertical cylinder is provided with a first vertical groove, an inclined groove, and a second vertical groove. The first vertical groove and the second vertical groove are connected by the inclined groove. The first vertical groove and the second vertical groove are respectively located on both sides of the vertical cylinder. A threaded rod is rotatably arranged in the middle of the vertical cylinder, and a driving motor for driving the threaded rod to rotate is fixed at the upper end of the vertical cylinder. A lifting sleeve is threadedly connected to the threaded rod. A cross bar is connected to the side end of the lifting sleeve. A sleeve is fixed to the side end of the material box, and the sleeve is rotatably sleeved outside the cross bar. A rotating mechanism for controlling the rotation of the sleeve is provided on the cross bar.
[0008] The rotating mechanism includes a toothed ring fixed on the outside of the sleeve. A motor bracket is fixed on the cross bar. A rotating motor is fixed on the motor bracket. A driving gear meshing with the toothed ring is fixed on the output shaft of the rotating motor.
[0009] With the above structure, after the material box rises to a certain height, the rotating motor can drive the driving gear to rotate, and then drive the sleeve and the material box to rotate through the toothed ring, so as to pour the recycled aluminum materials in the material box into the melting furnace. Similarly, when the rotating motor rotates in reverse, the material box can be reset.
[0010] A bearing is provided on the cross bar, and the bearing is located inside the first vertical groove.
[0011] With the above structure, during the lifting and lowering process of the cross bar, rolling friction is generated between the outer ring of the bearing and the inner walls of the first vertical groove, the inclined groove and the second vertical groove, which can reduce the friction force on the cross bar, reduce wear and tear and noise.
[0012] A guide plate is provided on the outer side of the material box. Two symmetrically distributed sliding grooves are formed on the guide plate. Two fixing bolts are provided on the material box, and the fixing bolts are slidably arranged in the sliding grooves at corresponding positions.
[0013] With the above structure, the guide plate can slide up and down along the material box. When filling the material box with materials, the guide plate can be moved down to reduce the obstruction to filling. After filling, the guide plate can be moved up. When pouring out the materials, the guide plate can guide the materials and pour the materials fully into the melting furnace to prevent the materials from scattering.
[0014] First racks are fixed on both sides of the guide plate. Two symmetrically distributed sliding sleeves are fixed on the material box. Second racks are slidably arranged in the sliding sleeves. Two rotating gears are rotatably arranged on the outer side of the material box, and the rotating gears are respectively engaged with the first racks and the second racks at corresponding positions.
[0015] With the above structure, when the material box descends, the second rack abuts against the ground and stops descending. The material box continues to descend. At this time, the rotating gear rotates while descending, and then drives the first rack to descend rapidly, so that the guide plate is automatically retracted and will not block the addition of materials to the material box.
[0016] A convex block is fixed on the outer side of the material box. A sliding rod is fixed on the convex block. A fixing plate is fixed on the guide plate. A round hole is formed in the fixing plate. The sliding rod passes through the round hole, and a return spring is sleeved on the sliding rod. The two ends of the return spring abut against the convex block and the fixing plate respectively.
[0017] With the above structure, when the material box ascends, the return spring will lift the fixing plate upward, and then drive the guide plate to ascend, which does not require manual operation by the operator and is more convenient to use.
[0018] Compared with the prior art, the feeding device for the regenerative aluminum melting furnace has the following advantages:
[0019] 1. Through the material box, the vertical cylinder, the threaded rod and the rotating mechanism, the material box can be driven to move to the other side of the vertical cylinder while ascending, and then the material box can be tilted to pour out the materials through the rotating mechanism, so that the material box diverges from the feeding port of the melting furnace when not feeding, will not block the pouring of molten aluminum, and does not require moving the feeding device, which is more convenient to use.
[0020] 2. Through the guide plate, the first rack, the second rack, the rotating gear and the return spring, the guide plate can be automatically retracted after the material box descends, without blocking the addition of materials to the material box. After the material box ascends, the guide plate can be automatically unfolded to prevent the materials from dispersing. There is no need for the operator to manually control the lifting of the guide plate, which makes it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Please refer to Figures 1-4 , this embodiment provides a feeding device for a recycled aluminum melting furnace, including a fixed base 1 and a material box 10 with an open upper end. A vertical cylinder 2 is fixed on the fixed base 1. A first vertical groove 3, an inclined groove 5, and a second vertical groove 4 are formed on the vertical cylinder 2, and the first vertical groove 3 and the second vertical groove 4 are connected by the inclined groove 5. The first vertical groove 3 and the second vertical groove 4 are respectively located on both sides of the vertical cylinder 2. A threaded rod 6 is rotatably arranged in the middle of the vertical cylinder 2, and a driving motor 7 for driving the threaded rod 6 to rotate is fixed at the upper end of the vertical cylinder 2. A lifting sleeve 8 is threadedly connected to the threaded rod 6. A cross bar 9 is connected to the side end of the lifting sleeve 8. A sleeve 11 is fixed to the side end of the material box 10, and the sleeve 11 is rotatably sleeved outside the cross bar 9. A rotating mechanism for controlling the rotation of the sleeve 11 is provided on the cross bar 9.
[0031] The rotating mechanism includes a toothed ring 12 fixed to the outside of the sleeve 11. A motor bracket 13 is fixed on the cross bar 9, and a rotating motor 14 is fixed on the motor bracket 13. A driving gear 15 meshing with the toothed ring 12 is fixed on the output shaft of the rotating motor 14. After the material box 10 rises to a certain height, the rotating motor 14 can drive the driving gear 15 to rotate, and then drive the sleeve 11 and the material box 10 to rotate through the toothed ring 12, so as to pour the recycled aluminum material in the material box 10 into the melting furnace. Similarly, when the rotating motor 14 rotates in reverse, the material box 10 can be driven to reset.
[0032] A bearing 16 is provided on the cross bar 9, and the bearing 16 is located inside the first vertical groove 3. During the lifting process of the cross bar 9, rolling friction is generated between the outer ring of the bearing 16 and the inner walls of the first vertical groove 3, the inclined groove 5, and the second vertical groove 4, which can reduce the friction force received by the cross bar 9, reduce wear and tear, and reduce noise.
[0033] A guide plate 17 is provided on the outside of the material box 10. Two symmetrically distributed sliding grooves 18 are formed on the guide plate 17. Two fixing bolts 19 are provided on the material box 10, and the fixing bolts 19 are slidably arranged in the corresponding sliding grooves 18. The guide plate 17 can slide up and down along the material box 10. When loading materials into the material box 10, the guide plate 17 can be moved down to reduce the obstruction to loading. After loading, the guide plate 17 can be moved up. When pouring out materials, the guide plate 17 can guide the materials and pour the materials into the melting furnace fully to prevent the materials from scattering.
[0034] On both sides of the guide plate 17, a first rack 20 is fixedly installed. On the material box 10, two symmetrically distributed sliding sleeves 21 are fixedly installed. A second rack 22 is slidably arranged in the sliding sleeve 21. On the outside of the material box 10, two rotating gears 23 are rotatably arranged, and the rotating gears 23 are respectively meshed with the first rack 20 and the second rack 22 at the corresponding positions. When the material box 10 descends, the second rack 22 abuts against the ground and stops descending. The material box 10 continues to descend. At this time, the rotating gear 23 rotates while descending, thereby driving the first rack 20 to descend at an accelerated speed, so that the guide plate 17 automatically retracts and will not block the addition of materials to the material box 10.
[0035] On the outside of the material box 10, a convex block 24 is fixedly installed. On the convex block 24, a slide rod 25 is fixedly installed. On the guide plate 17, a fixed plate 26 is fixedly installed, and a round hole is formed in the fixed plate 26. The slide rod 25 passes through the round hole, and a return spring 27 is sleeved on the slide rod 25. The two ends of the return spring 27 respectively abut against the convex block 24 and the fixed plate 26. When the material box 10 ascends, the return spring 27 will lift the fixed plate 26 upward, thereby driving the guide plate 17 to ascend, without the need for manual operation by the operator, which is more convenient to use.
[0036] In this embodiment, the above-mentioned fixing methods are all the most commonly used fixed connection methods in the art, such as welding, bolt connection, etc. The above-mentioned electrical components, such as the driving motor 7 and the rotating motor 14, are all products of the prior art and can be directly purchased and used in the market, and the specific principles will not be elaborated.
[0037] The working principle of the present utility model:
[0038] During use, the operator fills the recycled aluminum material into the material box 10, and then the driving motor 7 drives the threaded rod 6 to rotate, thereby driving the cross bar 9 to move upward along the first vertical groove 3, the inclined groove 5 and the second vertical groove 4 in sequence. During the ascending process, the material box 10 will move to the other side of the vertical cylinder 2 and align with the feeding port of the melting furnace. At this time, the rotating motor 14 can drive the driving gear 15 to rotate, thereby driving the sleeve 11 and the material box 10 to rotate through the toothed ring 12, and pouring the recycled aluminum material in the material box 10 into the melting furnace. After pouring out the materials, the rotating motor 14 and the driving motor 7 reverse, and the material box 10 moves downward and resets. After descending, the material box 10 diverges from the feeding port of the melting furnace and will not block the pouring of molten aluminum from the melting furnace. There is no need to move the feeding device, which is more convenient to use. Moreover, when the material box 10 descends, the second rack 22 abuts against the ground and stops descending. The material box 10 continues to descend. At this time, the rotating gear 23 rotates while descending, thereby driving the first rack 20 to descend at an accelerated speed, so that the guide plate 17 automatically retracts and will not block the addition of materials to the material box 10. When the material box 10 ascends, the return spring 27 will lift the fixed plate 26 upward, thereby driving the guide plate 17 to ascend, without the need for manual operation by the operator, which further facilitates the use of the operator.
[0039] The above has described in detail the preferred embodiments of the present patent. However, the present patent is not limited to the above embodiments, and various changes can be made without departing from the gist of the present patent within the scope of knowledge possessed by those of ordinary skill in the art.
