Description

Technical Field

[0001] This utility model relates to the field of medium-frequency electric furnace technology, specifically to a feeding mechanism for a medium-frequency electric furnace. Background Technology

[0002] Medium frequency electric furnaces are core equipment in the field of metal smelting, mainly used for melting metal materials such as scrap steel and alloy blocks.

[0003] Currently, the feeding methods for medium-frequency electric furnaces mainly rely on manual handling or simple overhead crane hoisting. Manual handling is labor-intensive, inefficient, and carries the risk of burns from high temperatures. Although some existing technologies use belt conveyors for feeding, they have the following obvious drawbacks in actual use:

[0004] When traditional flat belt conveyors are lifted at large angles, materials such as scrap steel and iron blocks are very easy to slide or roll off the belt due to their smooth surface and heavy weight, which can lead to interruption of feeding or even damage to equipment or personnel below.

[0005] Traditional belt conveyors mostly use friction drive. When the load is too heavy, such as when a large amount of scrap steel is fed in at one time, the drive roller and the belt are prone to slippage, which leads to transmission failure.

[0006] Existing feeding devices are mostly fixed, making it impossible to flexibly adjust the feeding points according to the location of different electric furnaces in the workshop, resulting in low equipment utilization. Therefore, there is an urgent need for a medium-frequency electric furnace feeding mechanism that can prevent heavy materials from sliding down, ensure smooth transmission, and facilitate easy movement. Utility Model Content

[0007] The purpose of this invention is to provide a feeding mechanism for a medium-frequency electric furnace to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a medium-frequency electric furnace, comprising a base plate,

[0009] Four casters are fixedly connected to the bottom end of the base plate, a support plate is fixedly connected to the upper left end of the base plate, a diagonal brace is fixedly connected to the top end of the support plate, and first baffles are fixedly connected to both the front and rear ends of the diagonal brace. A conveying assembly for conveying materials is rotatably connected between the first baffles. The conveying assembly includes a drive gear shaft, a driven gear shaft, and a toothed conveyor belt sleeved on the outside of the two. The drive gear shaft is driven to rotate by a drive device to drive the toothed conveyor belt.

[0010] Furthermore, the driven gear shaft is rotatably connected between the left ends of the two first baffles, and the two ends of the driven gear shaft are respectively rotatably connected to the corresponding first baffles.

[0011] Furthermore, the toothed conveyor belt is sleeved on the outside of the driven toothed shaft and the driving toothed shaft, and a plurality of transfer plates for carrying materials are fixedly connected to the outer surface of the toothed conveyor belt, and the transfer plates are spaced apart along the length direction of the toothed conveyor belt.

[0012] Furthermore, the active gear shaft is rotatably connected between the right ends of the two first baffles, and a rotating shaft is fixedly connected to the front end of the active gear shaft, the rotating shaft passing through one of the first baffles.

[0013] Furthermore, the driving device is a motor fixedly connected to the front end of the first baffle, and the output end of the motor is fixedly connected to the rotating shaft to drive the active gear shaft to rotate.

[0014] Furthermore, a guide plate is fixedly connected to the top left end of the inclined support plate, and the discharge end of the guide plate extends above the toothed conveyor belt to guide the material onto the toothed conveyor belt.

[0015] Furthermore, a bracket is fixedly connected to the upper right end of the base plate, a support base is fixedly connected to the top of the bracket, and a first conveyor belt is fixedly connected to the support base.

[0016] Furthermore, a second baffle is fixedly connected to both the front and rear ends of the support base. The second baffle extends along the transmission direction of the first conveyor belt to prevent materials from falling from both sides of the first conveyor belt.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] By setting up a first conveyor belt and a toothed conveyor belt, and through the relay conveying of the first conveyor belt and the toothed conveyor belt, the entire process of material input to furnace entry is automated, replacing traditional manual handling or semi-mechanized feeding. This reduces human intervention and significantly increases the material conveying capacity per unit time. It is especially suitable for batch processing of heavy materials such as scrap steel and alloy blocks, avoiding direct contact between humans and the high-temperature furnace body or heavy materials, reducing labor intensity and the risk of work-related injuries. At the same time, it reduces the dependence on the number of operators, saving labor costs. By setting up active and driven toothed shafts, the toothed conveyor belt meshes with the active and driven toothed shafts for transmission, avoiding the problems caused by excessive material weight or insufficient friction in traditional flat belt conveying. To address slippage issues and ensure stable power transmission, a transfer plate system is installed. These plates are spaced apart on the toothed conveyor belt surface, forming a "lifting" conveying structure that effectively prevents lumpy materials from sliding down during inclined conveying. This is especially suitable for irregularly shaped materials. First and second baffles provide lateral protection for materials in inclined and horizontal conveying sections, respectively, preventing materials from falling from both sides and causing damage or pollution to the workshop environment. Four casters are installed at the bottom of the base plate, allowing the equipment to move flexibly according to the furnace location and production needs. This adapts to different workshop layouts or scenarios where multiple furnaces share a single feeding mechanism, improving equipment utilization. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-4This utility model provides a technical solution for a feeding mechanism of a medium-frequency electric furnace: A feeding mechanism for a medium-frequency electric furnace includes a base plate 1, with four casters 2 fixedly connected to the bottom end of the base plate 1. By setting the casters 2, the equipment can be flexibly moved according to the position of the electric furnace and production needs, adapting to different workshop layouts or scenarios where multiple furnaces share a single feeding mechanism, thereby improving equipment utilization. A support plate 3 is fixedly connected to the upper left end of the base plate 1, and a diagonal brace 4 is fixedly connected to the top end of the support plate 3. First baffles 5 are fixedly connected to both the front and rear ends of the diagonal brace 4. By setting the first baffles 5 and the second baffles... 17. The first baffle 5 and the second baffle 17 provide lateral protection for the materials in the inclined and horizontal conveying sections, respectively, to prevent the materials from falling from both sides and causing losses or pollution to the workshop environment. The first baffle 5 is rotatably connected with an anti-slip transmission component. The transmission component adopts a forced meshing transmission structure, including an active gear shaft 9 and a driven gear shaft 7 that are rotatably installed between the first baffle 5 through bearings. In order to solve the problem of slippage under heavy load, the inner surface of the toothed conveyor belt 8 is provided with meshing teeth that match the tooth groove of the active gear shaft 9. Power is transmitted through the meshing principle of gear and rack, which completely eliminates the slippage phenomenon of traditional friction belts when conveying heavy metal materials.

[0029] Furthermore, to address the issue of irregular materials such as scrap steel easily rolling off, the outer surface of the toothed conveyor belt 8 is integrally formed or vulcanized with several transfer plates 13. The transfer plates 13 are evenly distributed along the conveying direction, and adjacent transfer plates 13 and the surface of the toothed conveyor belt 8 form a "hopper-shaped" carrying space for accommodating materials. When materials transition from the horizontal first conveyor belt 16 to the inclined toothed conveyor belt 8, the materials are caught above the transfer plates 13, thus being stably lifted to a higher position, eliminating the risk of material slippage.

[0030] The drive gear shaft 9 is rotatably connected between the right ends of the two first baffles 5. A rotating shaft 10 is fixedly connected to the front end of the drive gear shaft 9, and the rotating shaft 10 passes through one of the first baffles 5. The driving device is a motor 11 fixedly connected to the front end of the first baffle 5. The output end of the motor 11 is fixedly connected to the rotating shaft 10 to drive the drive gear shaft 9 to rotate. A guide plate 12 is fixedly connected to the top of the left end of the inclined support plate 4. The discharge end of the guide plate 12 extends above the toothed conveyor belt 8 to guide the material onto the toothed conveyor belt 8. A bracket 14 is fixedly connected to the upper right end of the base plate 1. A support base 15 is fixedly connected to the top of the bracket 14. A first conveyor belt 16 for receiving materials is provided on the support base 15. The first conveyor belt 16 and the toothed conveyor belt 8, through the relay conveying of the first conveyor belt 16 and the toothed conveyor belt 8, realize the full-process automation of materials from input to furnace, replace the traditional manual handling or semi-mechanized feeding, reduce human intervention, and greatly increase the material conveying capacity per unit time. It is especially suitable for batch processing of heavy materials such as scrap steel and alloy blocks, avoids direct contact between human and high-temperature furnace body or heavy materials, reduces labor intensity and risk of work injury, and at the same time reduces the dependence on the number of operators, saving labor costs. The front and rear ends of the support base 15 are fixedly connected with the second baffle 17, which extends along the transmission direction of the first conveyor belt 16 to prevent materials from falling from both sides of the first conveyor belt 16.

[0031] In use, the operator pushes the device to a suitable position using the casters 2 according to the location of the induction furnace opening, and locks the caster brakes. When feeding begins, the first conveyor belt 16 and the motor 11 are started simultaneously. First, the scrap steel, alloy blocks, and other materials to be melted are placed onto the horizontally positioned first conveyor belt 16. Under the limit of the second baffle 17, the materials are smoothly conveyed to the left. When the materials reach the end of the first conveyor belt 16, they fall onto the inclined toothed conveyor belt 8 under gravity. At this time, the motor 11 drives the drive gear shaft 9 to rotate, causing the toothed conveyor belt 8 to engage in forced transmission. The falling materials will be precisely wedged between two adjacent transfer plates 13. As the toothed conveyor belt 8 continues to rotate, the transfer plates 13 provide an upward thrust to the materials, preventing them from sliding down due to gravity. After being lifted to the top of the inclined support plate 4, the materials overturn the drive gear shaft 9 and, guided by the guide plate 12, accurately slide into the furnace opening of the induction furnace, completing the automatic feeding process.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
