Description

Technical Field

[0001] This utility model belongs to the field of waste aluminum recycling technology, specifically, it relates to an aluminum furnace feeding mechanism. Background Technology

[0002] Aluminum is a recyclable metal. Recycling waste aluminum can not only reduce the mining of alumina ore and the production of electrolytic aluminum, thereby reducing the consumption of natural resources and the damage to the environment, but also improve resource utilization and reduce production costs.

[0003] Waste aluminum recycling mainly uses smelting furnaces, and feeding the waste aluminum into the furnace is a crucial step in the process. Traditionally, this is done manually, which is not only labor-intensive and inefficient, failing to meet the furnace's operational schedule, but also susceptible to fatigue, negligence, and other factors, posing safety hazards. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide an aluminum furnace feeding mechanism to realize the automatic feeding of scrap aluminum.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A feeding mechanism for an aluminum furnace includes a hopper and a clamping mechanism. The bottom of the hopper is provided with an openable base plate, and a guide rail slider module is respectively provided on a pair of side walls of the hopper. Each slider of the guide rail slider module is hinged to a connecting rod between the slider and the corresponding side of the base plate. As the slider of the guide rail slider module moves up and down along its respective guide rail, the base plate can be opened or closed by the connecting rod. The clamping mechanism is located above the hopper, and the clamping mechanism can clamp onto the sliders of the pair of guide rail slider modules through its swing arm.

[0007] Furthermore, the base plate is of the split type, and ear plates that are hinged to the connecting rod are provided on its edge.

[0008] Furthermore, load-bearing seats are provided on the other pair of side walls of the hopper.

[0009] Furthermore, the clamping mechanism includes a frame on which a pair of swing arms that can rotate within are disposed, and a rocker assembly is disposed between the swing arms, which can drive the pair of swing arms to rotate synchronously outward or inward within the frame.

[0010] Furthermore, the swing arm is a U-shaped frame.

[0011] Furthermore, the rocker assembly includes a pair of opposing linkage structures. While the pair of linkage structures are disposed within a base, a pair of opposing swing arms and a power unit are disposed on the linkage structures. The power unit drives the pair of linkage structures to retract, thereby causing the pair of swing arms to move synchronously outward or inward.

[0012] Furthermore, the connecting rod structure is generally in the shape of a parallelogram.

[0013] Furthermore, a slot is formed on the base; a pin is provided at a pair of opposite hinge points where the connecting rod structure is connected to the base, and the pin can move up and down along the slot as the connecting rod structure contracts.

[0014] Furthermore, the power unit employs an electro-hydraulic actuator.

[0015] Furthermore, the upper end of the frame is provided with lifting lugs.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves automatic feeding of waste aluminum by setting up a hopper with an openable bottom plate and a clamping mechanism, which effectively solves the problems of high labor intensity, low efficiency and safety hazards of traditional manual feeding.

[0018] 2. The hopper and clamping mechanism of this utility model adopt a separate system solution, which can use multiple hoppers to correspond to one clamping mechanism, thereby making up for the downtime of the process and improving production efficiency. At the same time, one hopper can correspond to multiple clamping mechanisms, which is suitable for multi-station scenarios that require hopper separation.

[0019] 3. This utility model has a simple structure, novel design, multiple functions, and strong applicability.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0028] See Figure 1 As shown, an aluminum furnace feeding mechanism includes a hopper 1 and a clamping mechanism 2. The bottom of the hopper 1 is provided with an openable bottom plate 3, and a guide rail slider module 4 is respectively provided on a pair of side walls of the hopper 1. Each slider of the guide rail slider module 4 is hinged to the corresponding side of the bottom plate 3 with a connecting rod 5. As the slider of the guide rail slider module 4 moves up and down along its corresponding slide rail, the bottom plate 3 can be driven to open or close through the connecting rod 5. The clamping mechanism 2 is located above the hopper 1, and the clamping mechanism 2 can be clamped on the slider of the pair of guide rail slider modules 4 through its corresponding swing arm 22.

[0029] In this embodiment, the hopper 1 is welded from shaped steel and steel plate, and a load-bearing seat 6 is provided on its other two side walls; the bottom plate 3 is a split type, and it is a box-shaped structure welded from steel plate and stiffening plate, and ear plates are provided on its edges. When connected, one end of the connecting rod 5 is hinged to the ear plate, and the other end is hinged to the slider of the guide rail slider module 4.

[0030] Further, see Figure 2-3As shown, in this embodiment, the clamping mechanism 2 includes a frame 21, which is spliced ​​from steel profiles. A pair of swing arms 22 that can rotate within the frame 21 are provided on the frame 21. The swing arms 22 are U-shaped frames, and a rocker assembly 23 is provided between the swing arms 22. The rocker assembly 23 can drive the pair of swing arms 22 to rotate synchronously outward or inward within the frame 21, thereby clamping and releasing the slider to which the guide rail slider module 4 belongs.

[0031] In this embodiment, the rocker assembly 23 includes a pair of opposing connecting rod structures 231. The connecting rod structures 231 are generally parallelogram-shaped, and the pair of connecting rod structures 231 are disposed within a base 232. A pair of opposing swing arms 233 and a power unit 234 are disposed on the connecting rod structures 231. During installation, the base 232 and the power unit 234 are disposed on the frame 21, and the pair of opposing swing arms 233 are respectively hinged to the upper ends of the corresponding swing arms 22. During use, the power unit 234 drives the pair of connecting rod structures 231 to retract, thereby causing the pair of swing arms 233 to move synchronously outward or inward, thereby pulling the lower ends of the pair of swing arms 22 to rotate synchronously inward or outward within the frame 21, thus clamping and releasing the slider belonging to the guide rail slider module 4. In this embodiment, the power unit 234 is an electro-hydraulic actuator.

[0032] In this embodiment, a slot 2321 is provided on the base 232; a pin 235 is provided at a pair of opposite hinge points connecting the pair of connecting rod structures 231 and the base 232. As the connecting rod structure 231 retracts, the pin 235 can move up and down along the slot 2321, thereby ensuring the coordination and accuracy of the entire action while the connecting rod structure 231 retracts from the base 232.

[0033] In addition, the upper end of the frame 21 is provided with a lifting lug 24 to facilitate the lifting of the clamping mechanism 2, and the lifting lug 24 is welded to the frame 21.

[0034] The working principle of this utility model is as follows:

[0035] Before loading, the clamping mechanism 2 is mounted on the gantry crane (or other lifting mechanism) via the lifting lug 24.

[0036] During loading, hopper 1 is first placed in the loading area. At this time, the bottom plate 3 covers the bottom of hopper 1, sealing the outlet of hopper 1. Then, scrap aluminum is added to hopper 1. After it is full, the clamping mechanism 2 is moved above hopper 1 by the overhead crane. Driven by the power unit 234, the lower ends of the swing arms 22 rotate outward synchronously within the frame 21 (i.e., opening the two swing arms 22). Then, under the action of the overhead crane, the clamping mechanism 2 moves downward to a set height. The power unit 234 drives the lower ends of the swing arms 22 to rotate inward synchronously within the frame 21 (i.e., closing the two swing arms 22). The swing arm 22 is clamped on the slider of a pair of guide rail slider modules 4; then the clamping mechanism 2 is lifted upward by the overhead crane, thereby lifting the hopper 1. After being moved to the feeding position by the overhead crane, it is lowered so that the hopper 1 is supported by the load-bearing seat 6 on the upper end of the aluminum furnace feeding port. The clamping mechanism 2 is lowered continuously. At this time, under the action of gravity, the material in the hopper 1 presses open the bottom plate 3, thereby conveying the material in the hopper 1 into the aluminum furnace. During the opening of the bottom plate 3, the bottom plate 3 pulls the slider of the guide rail slider module 4 downward along its corresponding slide rail through the connecting rod 5.

[0037] After feeding is completed, the clamping mechanism 2 is lifted upward by the gantry crane. At this time, as the clamping mechanism 2 is lifted upward, the slider of the guide rail slider module 4 moves upward along its guide rail, thereby pulling the bottom plate 3 closed through the connecting rod 5. After the bottom plate 3 is completely closed, the hopper 1 is lifted to the set height synchronously with the clamping mechanism 2. The gantry crane then transfers the hopper 1 and the clamping mechanism 2 to the feeding area. After they are in place, the lower end of the swing arm 22 is driven by the power unit 234 to rotate outward synchronously within the frame 21 (i.e., open the two swing arms 22), releasing the clamping of the slider of the guide rail slider module 4. The clamping mechanism 2 is then lifted by the gantry crane, completing one feeding and transfer cycle. The above actions are repeated to form a work cycle.

[0038] Finally, it should be noted that during the feeding process, multiple hoppers 1 can be used to correspond to one clamping mechanism 2, thereby making up for the downtime of the feeding process of hopper 1 and thus improving production efficiency; or, one hopper 1 can be used to correspond to multiple clamping mechanisms 2, but this configuration is only suitable for multi-station scenarios that require separation of hopper 1.

[0039] In summary, this application enables stable material feeding, improves the quality and production efficiency of aluminum alloys, thereby enhancing the stability of the processing and product quality. This application features a simple structure, novel design, multiple functions, and strong applicability.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
