Description

Technical Field

[0001] This utility model relates to the field of waste copper recycling technology, and in particular to a rapid smelting furnace for recycling waste copper rods. Background Technology

[0002] Scrap copper recycling can not only reduce the mining of primary copper ore, reduce energy consumption and environmental pollution, but also effectively utilize waste resources.

[0003] In traditional scrap copper smelting furnaces, common heating methods such as flame heating suffer from uneven heating. The flame acts directly on the surface of the scrap copper, and heat transfer mainly relies on thermal conduction. The scrap copper closer to the flame is heated first, while the parts farther away from the flame take a longer time to reach the melting temperature. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a rapid smelting furnace for recycling scrap copper from metal rods.

[0005] This utility model is achieved by the following technical solution: a rapid smelting furnace for recycling scrap copper from metal rods, including a fixed frame, an outer furnace of the smelting furnace rotatably connected to the middle of the inner wall of the fixed frame, a top plate fixedly connected to the top of the fixed frame, a tilting device fixedly connected to the middle of the upper surface of the top plate, and a guide rod fixedly connected to the middle of the rear end of the top plate.

[0006] The tilting device includes a mounting frame, on one side of which a motor A is fixedly connected, and the output end of the motor A is driven by a winding reel.

[0007] Through the above technical solution, the rotating connection of the outer furnace of the smelting furnace provides the basic structure for the subsequent pouring of smelted materials, while the layout of the relevant components on the top plate prepares the framework for realizing specific functions.

[0008] As a further improvement to the above solution, a connecting steel rope is fixedly connected to the inner wall of the winding reel. The connecting steel rope is adapted to the guide rod, and a connector is fixedly connected to the other end of the connecting steel rope. The connector is connected to the outer furnace of the smelting furnace.

[0009] The above technical solution uses a motor-driven winding reel to control the tilting of the outer furnace of the smelting furnace. The operation is relatively simple and easy to control. The presence of the guide rod makes the movement of the connecting steel rope more stable, avoiding large-scale shaking during the pulling process, and improving the accuracy and safety of the tilting operation.

[0010] As a further improvement to the above scheme, an intermediate frequency coil is fixedly connected to the inner wall of the outer furnace of the smelting furnace, and an inner furnace of the smelting furnace is fixedly connected to the inner wall of the intermediate frequency coil.

[0011] The above technical solution uses a medium-frequency coil for heating and melting, which has high heating efficiency and can quickly bring the scrap copper to its melting point. Moreover, this electromagnetic induction heating method is relatively uniform, which can improve the quality of melting and reduce local overheating or incomplete melting.

[0012] As a further improvement to the above solution, a B motor is fixedly connected to one side of the upper surface of the top plate, and a lead screw is driven to the output end of the B motor.

[0013] The above technical solution, combining a motor and a lead screw, allows for precise control of the furnace lid's movement. This method enables automated operation, improves the accuracy and repeatability of the furnace lid's opening and closing, and facilitates operations such as feeding and observing the smelting furnace.

[0014] As a further improvement to the above solution, a limit rod is fixedly connected to the other side of the inner wall of the fixed frame.

[0015] Through the above technical solution, the presence of the limiting rod ensures the stability of the moving ring's movement, preventing the moving ring from rotating or wobbling when the screw rotates, thus enabling the furnace cover to open and close stably.

[0016] As a further improvement to the above solution, a movable ring is sleeved on the outer surface of both the lead screw and the limiting rod, and a furnace cover is fixedly connected to one side of the movable ring.

[0017] The above technical solution provides a simple and effective design for opening and closing the furnace cover. The movement of the furnace cover can be controlled by a single motor, and the movement is stable with the assistance of the limit rod, which helps to improve the operational convenience and automation of the entire smelting furnace.

[0018] As a further improvement to the above solution, a diagonal brace is fixedly connected to the bottom of the outer surface of the fixed frame, and a base is fixedly connected to the bottom of the fixed frame.

[0019] The above technical solutions improve the structural stability of the entire smelting furnace by setting up diagonal braces and a base, ensuring that the equipment will not easily tip over or shake during the smelting process, thus guaranteeing the safety and service life of the equipment.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This invention, through the design of a medium-frequency coil, enables rapid and uniform heating, which helps to completely melt scrap copper and improve the refining effect. The design of the tilting device allows the outer furnace of the smelting furnace to achieve stable tilting under the control of the motor, avoiding the copper splashing phenomenon that easily occurs when pouring copper in traditional smelting furnaces, thus improving operational safety. The opening and closing of the furnace cover is automatically controlled by a combination of motor B, lead screw and limit rod, improving the convenience and accuracy of operation.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figures 1-5 This embodiment of a rapid smelting furnace for recycling scrap copper from metal rods includes a fixed frame 1, an outer furnace 2 rotatably connected to the middle of the inner wall of the fixed frame 1, a top plate 3 fixedly connected to the top of the fixed frame 1, a tilting device 4 fixedly connected to the middle of the upper surface of the top plate 3, and a guide rod 5 fixedly connected to the middle of the rear end of the top plate 3.

[0032] The tilting device 4 includes a mounting frame 401, with an A motor 402 fixedly connected to one side of the mounting frame 401. The output end of the A motor 402 is connected to a winding reel 403. The fixed frame 1 provides structural support for the entire smelting furnace, and its inner wall is rotatably connected to the outer furnace 2 of the smelting furnace, allowing the outer furnace 2 to rotate within a certain range. The top plate 3 is fixed to the top of the fixed frame 1, providing a mounting base for other components. The tilting device 4 is installed in the middle of the top plate 3, and the guide rod 5 is installed in the middle of the rear end of the top plate 3. These components work together to provide a possible mechanism layout for the tilting operation of the outer furnace 2 of the smelting furnace.

[0033] A connecting steel rope 404 is fixedly connected to the inner wall of the winding reel 403. The connecting steel rope 404 is adapted to the guide rod 5. The other end of the connecting steel rope 404 is fixedly connected to a connector 405, which is connected to the outer furnace 2 of the smelting furnace. After the motor A 402 starts, it drives the winding reel 403 to rotate. The connecting steel rope 404 fixed to the inner wall of the winding reel 403 is wound and unwound during the rotation of the winding reel 403. The connecting steel rope 404 is adapted to the guide rod 5 to ensure a certain guiding effect during the movement. The connector 405 at the other end of the connecting steel rope 404 is connected to the outer furnace 2 of the smelting furnace. Thus, the forward and reverse rotation of the winding reel 403 pulls the outer furnace 2 of the smelting furnace, achieving the purpose of tilting.

[0034] An intermediate frequency coil 6 is fixedly connected to the inner wall of the outer furnace 2 of the smelting furnace, and an inner furnace 7 of the smelting furnace is fixedly connected to the inner wall of the intermediate frequency coil 6. When the intermediate frequency current passes through the intermediate frequency coil 6, an alternating magnetic field is generated around it. Since the inner furnace 7 of the smelting furnace is located on the inner wall of the intermediate frequency coil 6, under the action of the alternating magnetic field, the scrap copper in the inner furnace 7 will generate eddy currents due to electromagnetic induction. The eddy currents cause the scrap copper to heat up, thereby achieving smelting.

[0035] A B motor 8 is fixedly connected to one side of the upper surface of the top plate 3. The output end of the B motor 8 is connected to a lead screw 9. After the B motor 8 starts, it drives the lead screw 9 to rotate. The rotation of the lead screw 9 will be converted into linear motion of the moving ring 11 on the lead screw 9, which prepares for the subsequent movement of the furnace cover 12.

[0036] A limiting rod 10 is fixedly connected to the other side of the inner wall of the fixed frame 1. The limiting rod 10 is fixedly connected to the other side of the inner wall of the fixed frame 1. It works together with the lead screw 9 to move the moving ring 11. When the moving ring 11 moves along the lead screw 9, the limiting rod 10 restricts the rotational freedom of the moving ring 11, ensuring that the moving ring 11 can only make linear motion.

[0037] Both the lead screw 9 and the limiting rod 10 have a moving ring 11 sleeved on their outer surfaces. A furnace cover 12 is fixedly connected to one side of the moving ring 11. When the B motor 8 drives the lead screw 9 to rotate, the moving ring 11 sleeved on the outer surfaces of the lead screw 9 and the limiting rod 10 will move linearly along the lead screw 9. Since the furnace cover 12 is fixedly connected to one side of the moving ring 11, the furnace cover 12 will open and close as the moving ring 11 moves.

[0038] A diagonal brace 13 is fixedly connected to the bottom of the outer surface of the fixed frame 1, and a base 14 is fixedly connected to the bottom of the fixed frame 1. The diagonal brace 13 is fixed to the bottom of the outer surface of the fixed frame 1 to provide additional support for the fixed frame 1 and enhance the stability of the entire structure. The base 14 is fixed to the bottom of the fixed frame 1 and is used to place the smelting furnace as a whole on a suitable working plane to distribute the weight of the entire equipment.

[0039] The implementation principle of a rapid smelting furnace for recycling scrap copper rods in this embodiment is as follows: A smelting furnace outer furnace 2 is rotatably connected to the middle of the inner wall of the fixed frame 1. This allows the outer furnace 2 to rotate within a certain range, providing the possibility for subsequent tilting operations. When motor A 402 starts, the winding reel 403 rotates, pulling the outer furnace 2 through the connecting steel rope 404 and the connector 405, causing it to rotate around the rotating connection point, thereby achieving the tilting action. A medium-frequency coil 6 is fixedly connected to the inner wall of the outer furnace 2, and a smelting furnace inner furnace 7 is fixedly connected to the inner wall of the medium-frequency coil 6. When the medium-frequency current passes through the medium-frequency coil 6, an alternating magnetic field is generated around it. Since the smelting furnace inner furnace 7 is located on the inner wall of the medium-frequency coil 6, the alternating magnetic field... Under the action of electromagnetic induction, the scrap copper in the inner furnace 7 will generate eddy currents, which will heat up the scrap copper itself, thus achieving smelting. A B motor 8 is fixedly connected to one side of the upper surface of the top plate 3. The output end of the B motor 8 is connected to a lead screw 9. A limit rod 10 is fixedly connected to the other side of the inner wall of the fixed frame 1. A moving ring 11 is sleeved on the outer surface of both the lead screw 9 and the limit rod 10. A furnace cover 12 is fixedly connected to one side of the moving ring 11. After the B motor 8 is started, it drives the lead screw 9 to rotate. The rotation of the lead screw 9 will be converted into linear motion of the moving ring 11 on the lead screw 9. The limit rod 10 plays the role of restricting the rotational freedom of the moving ring 11, ensuring that the moving ring 11 can only make linear motion. The furnace cover 12 opens and closes as the moving ring 11 moves.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
