Description

Technical Field

[0001] This utility model relates to the field of smelting furnace equipment technology, and in particular to a smelting furnace charging device. Background Technology

[0002] During the process of loading materials into the smelting furnace, forklifts are usually used to directly fork the materials into the furnace. However, this method of directly loading materials into the smelting furnace has several significant drawbacks: When loading, the aluminum ingots need to be held in place by the furnace edge before the forklift is reversed to complete the operation. This not only severely damages the furnace edge refractory and shortens the service life of the smelting furnace, but the forklift forks are also prone to directly damaging the upper edge of the furnace body. During unloading, the forklift is too close to the smelting furnace, which reduces the service life of the forklift's windshield. Materials are prone to spillage during transportation, requiring operators to repeatedly forklift materials, increasing labor intensity and potentially creating safety risks. Furthermore, if the forklift is overloaded, it can cause the forklift to tip over, leading to a safety accident. Utility Model Content

[0003] The purpose of this utility model is to provide a charging device for a smelting furnace to solve the problems existing in the prior art, avoid spillage during material transportation, reduce labor intensity, and improve work efficiency.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a charging device for a smelting furnace, including a fixed base, a charging hopper, a cover plate, a discharge driving device, and a cover plate driving device. The forks of a forklift can insert into the fixed base and lift the fixed base. The discharge end of the charging hopper is hinged to the fixed base. The cover plate is hinged to the charging hopper and can close the opening of the charging hopper. The discharge driving device and the cover plate driving device are both fixedly installed on the fixed base. The output end of the discharge driving device is connected to the charging hopper, and the output end of the cover plate driving device is connected to the cover plate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The purpose of this utility model is to provide a charging device for a smelting furnace to solve the problems existing in the prior art, avoid spillage during material transportation, reduce labor intensity, and improve work efficiency.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] This utility model provides a charging device for a smelting furnace, such as Figures 1-2As shown, the device includes a fixed base 1, a hopper 2, a cover plate 3, an unloading drive device 4, and a cover plate drive device 5. The forklift forks can insert into the fixed base 1 and lift it. The discharge end of the hopper 2 is hinged to the fixed base 1, and the cover plate 3 is hinged to the hopper 2, closing the opening of the hopper 2. Both the unloading drive device 4 and the cover plate drive device 5 are fixedly mounted on the fixed base 1. The output end of the unloading drive device 4 is connected to the hopper 2, and the output end of the cover plate drive device 5 is connected to the cover plate 3. Before loading, the cover plate drive device 5 controls the cover plate 3 to open; after loading, the cover plate 3 is closed, reducing material loss, alleviating operator workload, and simultaneously improving loading efficiency and accuracy. The forklift lifts the fixed base 1 with its forks and transports the smelting furnace loading device. Upon reaching the unloading point, the cover plate drive device 5 controls the cover plate 3 to open, and the unloading drive device 4 controls the hopper 2 to tilt and discharge material. During unloading, there is no need to rely on the furnace edge to hold the aluminum ingot, thus avoiding damage to the furnace edge casting material, furnace top edge, and furnace bottom from the source, while also reducing the impact on the forklift windshield. Since the inner side of the lower furnace edge of the smelting furnace has a certain inclination angle, ensuring that the inclination angle of the unloading drive device 4 lifting the charging hopper 2 is the same as the inclination angle of the lower furnace edge of the smelting furnace allows the material to smoothly enter the furnace from the charging hopper along a uniform inclination path by gravity. This ensures that the material's sliding trajectory does not collide or interfere with the inner wall of the furnace, guaranteeing a continuous and uninterrupted unloading process. The material will not stagnate or accumulate at the joints, avoiding high-temperature corrosion of equipment components by the material, and further improving the stability and safety of unloading.

[0018] In a further preferred embodiment of this utility model, the unloading drive device 4 is a hydraulic cylinder, and the cover plate drive device 5 is a hydraulic cylinder. Hydraulic power is transmitted to the hydraulic cylinder through a high-pressure hose, so that the cylinder performs a lifting action, realizing the tilting of the hopper and the opening of the cover plate 3. The action response is precise and the driving force is stable.

[0019] In a further preferred embodiment of this utility model, the smelting furnace charging device also includes a weighing sensor 6, which is fixedly installed on the fixed base 1 and used to monitor the material mass in the charging hopper 2. The weighing sensor 6 establishes a signal connection with the controller inside the forklift, and can synchronously feed back material weight data; when the material weight exceeds the preset value, the intelligent display controller will automatically cut off the power to the forklift controller, restricting the forklift from starting, thus avoiding the risk of tipping over due to overloading from the source and greatly improving operational safety.

[0020] In a further preferred embodiment of this utility model, both the inner wall of the hopper 2 and the inner wall of the cover plate 3 are covered with a fire-resistant layer to improve the service life of the hopper 2.

[0021] In a further preferred embodiment of this utility model, both the hopper 2 and the cover plate 3 are made of high-strength alloy steel.

[0022] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
