Description

Technical Field

[0001] This utility model relates to the field of metal smelting technology, and in particular to a metal smelting raw material feeding device. Background Technology

[0002] In industrial production, metal smelting is an indispensable and crucial link in many industries such as aerospace, automobile manufacturing, and machining. Its main function is to heat metal raw materials to a molten state at high temperatures to facilitate subsequent processing steps such as casting and forging. With the rapid development of modern industry, increasingly higher demands are being placed on the efficiency, product quality, and production safety of metal smelting. As a preliminary step in the smelting process, the rationality and efficiency of the handling and transportation of metal raw materials directly affect the operational effectiveness of the entire smelting production line.

[0003] Currently, existing metal smelting raw material feeding devices have many shortcomings in practical applications. In terms of raw material handling, traditional devices often employ simple crushing structures, which are insufficient to fully pulverize the metal raw materials, resulting in large and uneven particle sizes. This leads to a small contact area between the raw material and the heat source during smelting, resulting in uneven heating, prolonged smelting time, reduced smelting efficiency, and the need for more energy to reach the melting temperature. In the raw material conveying and metering stages, existing devices mostly rely on manual control or low-precision mechanical conveying methods, easily leading to unstable raw material conveying volumes and large metering errors. This results in inconsistent raw material quantities fed into the smelting furnace each time, affecting the stability of the smelting process, increasing product scrap rates, and reducing production efficiency. Furthermore, during the process of pouring raw materials into the smelting port, existing devices typically require manual operation. Operators must approach the high-temperature smelting port, which is not only physically demanding but also highly susceptible to burns from high-temperature radiation or accidental contact, posing significant safety hazards. Human error can also cause production delays, further impacting production efficiency. Utility Model Content

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of a metal smelting raw material guiding device, comprising a discharge platform 1, a crushing box 2 disposed at the right end of the discharge platform 1, two crushing rollers 3 disposed inside the crushing box 2, a rotating rod 4 fixedly connected to the middle of each of the two crushing rollers 3, both ends of the two rotating rods 4 being rotatably connected to the two sides of the crushing box 2 via rotating shafts, gears 5 fixedly connected to the outer wall of the front end of each of the two rotating rods 4, the two gears 5 being meshed together, the front end of the left rotating rod 4 being fixedly connected to the drive end of a first motor 6, and the rear end of the first motor 6 being fixedly connected to a protective shell. 7. On the front side, a connecting pipe 8 is fixedly connected to the lower end of the crushing box 2. A guide pipe 9 is fixedly connected to the lower end of the connecting pipe 8. A second motor 11 is fixedly connected to the left end of the guide pipe 9. A screw conveyor 10 is fixedly connected to the drive end of the second motor 11. The screw conveyor 10 is located inside the guide pipe 9. A support frame is rotatably connected to the right end of the screw conveyor 10. The support frame is fixedly connected to the inner wall of the right end of the guide pipe 9. The left end of the screw conveyor 10 is rotatably connected to the guide pipe 9. A discharge pipe 12 is fixedly connected to the right end of the guide pipe 9. A solenoid valve 13 is fixedly connected to the middle of the discharge pipe 12.

[0019] Specifically, when using this device for metal smelting, the operator first needs to put the metal raw material to be processed into the crushing box 2. After starting the device, the first motor 6 will drive the left rotating rod 4 to rotate clockwise. Since the left and right rotating rods 4 are meshed with each other through gears 5, the rotation of the left rotating rod 4 will cause the right rotating rod 4 to rotate counterclockwise synchronously, thereby causing the two crushing rollers 3 to rotate relative to each other towards the center position. In this process, the metal raw material will be fully crushed and broken by the two crushing rollers 3, and finally formed into powder.

[0020] The pulverized metal powder enters the feed pipe 9 through the connecting pipe 8. At this time, the second motor 11 drives the screw conveyor 10 to operate, conveying the metal powder along the feed pipe 9 to the discharge pipe 12. After the solenoid valve 13 at the discharge pipe 12 is opened, the metal powder will be discharged into the hopper 17 below.

[0021] Reference Figure 1 and Figure 4 A hopper 17 is provided at the lower end of the feeding pipe 12. A second hydraulic rod 21 is rotatably connected to the outer wall of the left side of the hopper 17. A sliding plate 15 is rotatably connected to the lower end of the second hydraulic rod 21. A metering sensor 16 is provided at the upper end of the sliding plate 15 for detecting the weight of the material in the hopper 17. The lower right side of the hopper 17 is rotatably connected to the right side of the sliding plate 15. The front and rear sides of the sliding plate 15 are slidably connected to the inner wall of the electric slide rail 14. A first hydraulic rod 20 is rotatably connected to the upper end of the hopper 17. A fixed rod 19 is rotatably connected to the driving end of the first hydraulic rod 20. A discharge gate 18 is fixedly connected to the lower end of the fixed rod 19. The upper end of the discharge gate 18 is rotatably connected to the upper right side of the hopper 17.

[0022] Specifically, the metering sensor 16 installed on the sliding plate 15 accurately measures the amount of powder entering the hopper 17. When the measured value reaches the preset threshold, the metering sensor 16 will automatically send a signal to control the solenoid valve 13 to close and simultaneously shut down the second motor 11, thereby stopping the unloading of material into the hopper 17.

[0023] The hopper 17, filled with metal powder, is conveyed to the melting port by an electric slide rail 14. Upon arrival, the second hydraulic rod 21 is activated, its drive end lifting the left end of the hopper 17 upwards, tilting it to complete the unloading action. Simultaneously, the drive end of the first hydraulic rod 20 retracts, opening the discharge gate 18 to allow the metal powder to enter the melting area. A sealing rubber ring is installed at the contact surface between the discharge gate 18 and the hopper 17. Combined with the first hydraulic rod 20, this ensures the discharge gate 18 remains closed during transport, preventing metal powder leakage. A vibration device is also installed on the outer wall of the hopper 17. During unloading, this device vibrates to assist in unloading, ensuring complete discharge of the metal powder from the hopper 17. This design allows operators to maintain a safe distance from the melting port throughout the operation, effectively reducing the risk of burns from high temperatures.

[0024] Working principle: When using this device, the operator pours the metal raw material to be melted into the crushing box 2. The first motor 6 drives the left rotating rod 4 to rotate clockwise, and the right rotating rod 4 rotates counterclockwise under the meshing action of the two gears 5. Therefore, both crushing rollers 3 rotate towards the center, thereby crushing the metal raw material into powder. The crushed metal raw material enters the connecting pipe 8 and then the guide pipe 9. The second motor 11 drives the screw conveyor 10 to guide the metal raw material to the discharge pipe 12. The solenoid valve 13 discharges the metal raw material into the hopper 17. The metering sensor 16 accurately measures the material. When the set threshold is reached, the metering sensor 16 stops the discharge by controlling the closing of the solenoid valve 13 and the second motor 11. The hopper 17, filled with metal raw materials, is conveyed to the melting port by the electric slide rail 14. Upon reaching the melting port, the second hydraulic rod 21 is activated. The drive end of the second hydraulic rod 21 pushes the left end of the hopper 17 upward to discharge the material. The drive end of the first hydraulic rod 20 retracts, causing the unloading gate 18 to open. The outer wall of the hopper 17 is equipped with a vibration device to assist in unloading. This feature allows the operator to stay away from the melting port throughout the process, reducing the risk of burns.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
