Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of feeding devices, and more specifically, to a feeding device for a medium-frequency furnace. Background Technology
[0002] Medium frequency furnaces, as key equipment for metal melting and smelting, play an important role in industries such as electrolytic aluminum. Their working principle utilizes electromagnetic induction to convert industrial frequency alternating current into medium frequency current, causing eddy currents in the metal material, which then heats and melts it. Typically, medium frequency furnaces are large and tall; for ease of operation and feeding, the upper feed inlet is usually level with the ground. In existing feeding methods, besides relying entirely on manual feeding, the most common method is to use equipment such as electric hoists. The specific procedure is to first use the electric hoist to lift the hopper containing the material, and then open the discharge port of the hopper to feed the material.
[0003] However, this method has many drawbacks. On the one hand, the operation is extremely inconvenient; operating the electric hoist requires certain skills, and the lifting and unloading steps are cumbersome, consuming time and manpower. On the other hand, it is difficult to accurately control the feed rate, which can adversely affect the stability of the smelting process and product quality. For example, in the electrolytic aluminum industry, unstable feed rates may lead to uneven aluminum liquid composition, affecting the quality of the final aluminum product. Therefore, developing a convenient feeding device that can accurately control the feed rate has become an urgent need to improve the production efficiency and product quality of intermediate frequency furnaces. Utility Model Content
[0004] The purpose of this invention is to provide a feeding device for a medium-frequency furnace, which can efficiently and conveniently feed materials into the medium-frequency furnace and better control the amount of materials fed.

[0006] Furthermore, a hook is provided at the end of the pull rod away from the scraper.
[0007] Furthermore, a sliding groove is provided at the bottom of the storage tank, and the pull rod is disposed in the sliding groove.
[0008] Furthermore, a limiting ring is provided at the bottom of the opening side of the storage tank, and the end of the pull rod away from the scraper passes through the limiting ring.
[0009] Furthermore, it also includes a pair of guide rails on the ground, with the rollers mounted on the guide rails and the rollers connected to a power unit.
[0010] Furthermore, it also includes a base fixed to the ground, a connecting hole opened on the base, a connecting rod detachably connected to the connecting hole and vertically arranged, a traction rope connected to the upper end of the connecting rod, and a hanging ring located at the end of the traction rope away from the connecting rod; the base is located between a pair of guide rails, and the hook can be hung on the hanging ring.
[0011] Furthermore, the inner wall of the storage tank is provided with limiting strips on both opposite sides, and the scraper is provided with limiting grooves on both opposite sides, with the limiting strips slidably disposed in the limiting grooves.
[0012] Furthermore, baffles are provided on both sides of the opening side of the storage tank, and a discharge plate is hinged to the lower side of the opening side of the storage tank. The discharge plate is connected to a driving device. The discharge plate is located between a pair of baffles, and one end of the discharge plate is hinged to the lower side of the storage tank via a rotating shaft. The driving device is used to drive the discharge plate to rotate around the rotating shaft. The driving device includes a telescopic cylinder horizontally located below the storage tank, a hinge rod hinged to the movable end of the telescopic cylinder, and a limiting tube horizontally located and fixedly connected to the support frame. The cylinder body of the telescopic cylinder is fixedly connected to the support frame, the telescopic rod of the telescopic cylinder is slidably located in the limiting tube, and the end of the hinge rod away from the telescopic cylinder is hinged to the lower side of the baffle.
[0013] Furthermore, the support frame is provided with a plurality of vertically arranged columns, and a pair of inclined guide plates are provided on the columns; the pair of guide plates are respectively arranged on both sides of the storage tank.
[0014] Furthermore, the support frame is provided with multiple buffer pads, and the lower side of the storage tank is fixedly mounted on the buffer pads.
[0015] The technical solution of this utility model has at least the following advantages and beneficial effects: The medium-frequency furnace feeding device of this utility model allows raw materials to be temporarily stored in a storage tank during use. When feeding is required, the support frame is pushed towards the medium-frequency furnace, aligning the opening of the storage tank with the furnace's feed inlet. Then, the vibration device is activated, causing the material in the storage tank to slowly move towards the furnace under vibration (due to the slight inclination of the storage tank, the material will naturally move downwards under vibration) and fall into the furnace through the opening. The feeding amount can be controlled by the vibration time. After feeding is completed, the support frame and storage tank return to their original positions. After a certain period of use, the scraper can be moved inside the storage tank by pulling a lever, thereby scraping off the material adhering to the inner wall of the storage tank, preventing the material from adhering to the tank for a long time. By using a support frame and a storage tank as an intermediate transfer device for feeding, not only can the feeding operation be made more efficient and convenient, but the amount of feeding can also be better controlled, and the feeding process can be better controlled manually or automatically.

Detailed Implementation
[0018] Example The following description, in conjunction with specific embodiments, further illustrates the points, as shown in the appendix. Figure 1 -Appendix Figure 8 As shown, the medium-frequency furnace feeding device of this embodiment includes a horizontally arranged support frame 10, a storage trough 20 inclinedly mounted on the support frame 10, a plurality of rollers 11 disposed on the lower side of the support frame 10, a vibration device 12 fixedly disposed on the lower side of the storage trough 20, a scraper 21 vertically disposed inside the storage trough 20, and a pull rod 22 connected to the scraper 21; the storage trough 20 has a long strip structure, the upper side and one end of the storage trough 20 are open sides, and the scraper 21 is attached to the sealed end of the inner wall of the storage trough 20; the length direction of the storage trough 20 is perpendicular to the plane where the scraper 21 is located. Specifically, during use, raw materials are temporarily stored in the storage tank 20. When it is necessary to add material to the induction furnace, the support frame 10 is pushed towards the induction furnace so that the opening side of the storage tank 20 is aligned with the feed port of the induction furnace. Then, the vibration device 12 is started (the vibration device 12 can be a conventional vibration motor, such as an eccentric motor). Under the action of vibration, the material in the storage tank 20 slowly moves towards the induction furnace (since the storage tank 20 is slightly inclined, the material will naturally move downwards under the action of vibration) and falls into the induction furnace through the opening side of the storage tank 20. The amount of material added can be controlled by the vibration time. After the material is added, the support frame 10 and the storage tank 20 can be returned to their original positions. After a certain period of use, the scraper 21 can be moved inside the storage tank 20 by pulling the pull rod 22 to scrape the material adhering to the inner wall of the storage tank 20 off the inner wall of the storage tank 20, thus preventing the material from adhering to the inside of the storage tank 20 for a long time. By using the support frame 10 and the storage tank 20 as intermediate transfer devices for feeding, not only can more efficient and convenient feeding operations be achieved, but the amount of feeding can also be better controlled, and the feeding process can be better controlled manually or automatically.
[0019] In this embodiment, the end of the pull rod 22 away from the scraper 21 is provided with a hook 23. Specifically, the pull rod 22 can be fixed to other fixed equipment by the hook 23, and then the support frame 10 and the storage tank 20 can be moved, thereby achieving the purpose of scraping material by the scraper 21 in the storage tank 20.
[0020] In this embodiment, a groove 25 is provided at the bottom of the storage tank 20, and the pull rod 22 is disposed in the groove 25. Specifically, the pull rod 22 is embedded in the groove 25 as much as possible, which can avoid the pull rod 22 itself from affecting the movement of materials, and can also prevent the materials from damaging the pull rod 22.
[0021] In this embodiment, a limiting ring is provided at the bottom of the opening side of the storage tank 20, and the end of the pull rod 22 away from the scraper 21 passes through the limiting ring. Specifically, by limiting the limiting ring, the pull rod 22 can be kept moving within the limiting ring and the slide groove 25, preventing the pull rod 22 from coming out of the limiting ring, and also allowing the scraper 21 to maintain a straight movement better.
[0022] In this embodiment, a pair of guide rails 31 are also provided on the ground 30, and rollers 11 are mounted on the guide rails 31. The rollers 11 are connected to a power device. Specifically, by providing guide rails 31 on the ground 30 and mounting rollers 11 on the guide rails 31, the support frame 10 and the storage tank 20 can maintain reciprocating linear movement more effectively. Connecting a power device such as a motor to the rollers 11 enables the support frame 10 to have its own movement function.
[0023] In this embodiment, it also includes a base 32 fixed to the ground 30, a connecting hole 33 on the base 32, a vertically arranged connecting rod 34 detachably connected to the connecting hole 33, a traction rope 35 connected to the upper end of the connecting rod 34, and a hanging ring on the end of the traction rope 35 away from the connecting rod 34; the base 32 is located between a pair of guide rails 31, and the hook 23 can be hooked onto the hanging ring. Specifically, when it is necessary to use the scraper 21 to scrape the material in the storage trough 20, the connecting rod 34 can be inserted into the connecting hole 33 of the base 32 (or threaded connection), and then the hanging ring of the traction rope 35 on the connecting rod 34 can be hooked onto the hook 23 of the pull rod 22 (as shown in the attached figure). Figure 4 As shown, by using a power unit to drive the support frame 10 and the storage tank 20 to move away from the connecting rod 34, the traction rope 35 and the pull rod 22 can be used to pull the scraper 21 to move in the storage tank 20 to scrape the material inside the storage tank 20. After scraping is completed, the connecting rod 34 can also be used to push the pull rod 22 and the scraper 21 back to their original positions.
[0024] In this embodiment, limiting strips are provided on both opposite sides of the inner wall of the storage tank 20, and limiting grooves are provided on both opposite sides of the scraper 21. The limiting strips are slidably disposed in the limiting grooves. Specifically, the setting of the limiting strips and limiting grooves makes the movement of the scraper 21 more stable and avoids the scraper 21 from tilting or other situations.
[0025] In this embodiment, baffles 26 are provided on both sides of the opening side of the storage tank 20. A discharge plate 27 is hinged to the lower side of the opening side of the storage tank 20. The discharge plate 27 is connected to a driving device 28. The discharge plate 27 is located between a pair of baffles 26. One end of the discharge plate 27 is hinged to the lower side of the storage tank 20 via a rotating shaft. The driving device 28 is used to drive the discharge plate 27 to rotate around the rotating shaft. The driving device 28 includes a telescopic cylinder 281 horizontally located below the storage tank 20, a hinge rod 283 hinged to the movable end of the telescopic cylinder 281, and a limiting tube 282 horizontally located and fixedly connected to the support frame 10. The cylinder body of the telescopic cylinder 281 is fixedly connected to the support frame 10. The telescopic rod of the telescopic cylinder 281 is slidably located in the limiting tube 282. The end of the hinge rod 283 away from the telescopic cylinder 281 is hinged to the lower side of the baffle 26. Specifically, the baffle 26 and the discharge plate 27 form a structure similar to a discharge nozzle, which can better control the flow of materials. When the drive device 28 drives the discharge plate 27 to rotate downward, the material can be discharged from the storage tank 20 more effectively. When the drive device 28 drives the discharge plate 27 to rotate upward, the opening sides of the pair of storage tanks 20 can be blocked, which can prevent the material from falling out.
[0026] In this embodiment, the support frame 10 is provided with a plurality of vertically arranged columns 14, and a pair of inclined guide plates 15 are provided on the columns 14; the pair of guide plates 15 are respectively arranged on both sides of the storage tank 20. Specifically, the guide plates 15 form a funnel-like structure, so that the material can enter the storage tank 20 more effectively.
[0027] In this embodiment, the support frame 10 is provided with multiple buffer pads 13, and the lower side of the storage tank 20 is fixedly mounted on the buffer pads 13. Specifically, by setting the buffer pads 13, the vibration of the storage tank 20 can be avoided or reduced from being transmitted to the support frame 10. Furthermore, the storage tank 20 does not contact the column 14 or the guide plate 15.
[0028] In summary, the intermediate frequency furnace feeding device of this embodiment discharges raw materials into the storage tank 20 for temporary storage during use. When it is necessary to feed the intermediate frequency furnace, the support frame 10 is pushed towards the intermediate frequency furnace so that the opening side of the storage tank 20 is aligned with the feed port of the intermediate frequency furnace. Then, the vibration device 12 is activated, so that the material in the storage tank 20 slowly moves towards the intermediate frequency furnace under the action of vibration (since the storage tank 20 is slightly inclined, the material will naturally move downward under the action of vibration) and falls into the intermediate frequency furnace through the opening side of the storage tank 20. The amount of feeding can be controlled by the vibration time. After feeding is completed, the support frame 10 and the storage tank 20 can be returned to their original positions. In this way, by using the support frame 10 and the storage tank 20 as intermediate transfer devices for feeding, not only can more efficient and convenient feeding operations be achieved, but also the amount of feeding can be better controlled, and the feeding process can be better controlled manually or automatically.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
