Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal smelting technology, and in particular to a permanent magnet stirring device for non-ferrous alloys. Background Technology

[0002] In the metallurgical industry, stirring non-ferrous metals is a key process in smelting, refining, and alloying. Most of these processes involve driving the flow of molten metal through mechanical paddles, electromagnetic induction, and permanent magnet induction, promoting uniform mixing of components, balanced temperature distribution, and enhanced reaction kinetics. Mechanical stirring is suitable for high-temperature smelting, while electromagnetic stirring achieves contactless and clean stirring. This process can effectively improve metal purity, improve microstructure, and ensure product quality and production efficiency, making it one of the core links in non-ferrous metal production.

[0003] Existing permanent magnet stirring for non-ferrous metals utilizes the magnetic field generated by permanent magnets to drive the flow of melt, achieving composition homogenization and grain refinement. It features no need for power supply and high energy efficiency, making it suitable for non-ferrous alloy smelting. However, during the process of fixing the permanent magnet to the furnace, it is manually positioned and fixed by the naked eye, which can easily lead to the permanent magnet shifting during the fixing process, resulting in poor stirring effect. It is also impossible to accurately position the magnet, and most of the time, the stirred molten metal alloy needs to be poured out manually, which poses a significant safety hazard.

[0004] Therefore, those skilled in the art have provided a permanent magnet stirring device for non-ferrous alloys to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a permanent magnet stirring device for non-ferrous alloys. This device enables precise positioning and clamping of the stirring cover when it is fixedly connected to the furnace, improving the efficiency of the fixed connection. Furthermore, it allows for the pouring of the stirred molten metal alloy, reducing the risks associated with manual pouring and improving the efficiency and safety of the pouring process.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A permanent magnet stirring device for non-ferrous alloys includes a base plate, a rotating assembly, a furnace, and a stirring cover. A drive motor is fixedly installed in the middle of the upper surface of the stirring cover, and a permanent magnet is fixedly installed at the output end of the drive motor. Receiving grooves are formed on both sides of the middle of the lower surface of the stirring cover, and positioning assemblies are fixedly installed inside each of the two receiving grooves. Magnetic strips are fixedly installed on the upper sides of both sides of the furnace. Semicircular grooves are formed in the middle of the opposite sides of the two magnetic strips, and positioning grooves are formed in the middle of the opposite sides of the two semicircular grooves.

[0008] The rotating assembly includes a first bearing seat, a second bearing seat, a rotating rod, a fixed plate, a connecting plate, two electric guide rails and a limiting rod. Connecting blocks are fixedly installed on the upper part of the middle of both sides of the connecting plate. Dampers are fixedly sleeved on both the front and rear ends of the limiting rod. Buffer springs are fixedly installed between the two dampers.

[0009] The two positioning components include two movable plates, four sliding rods and two electric push rods. A magnetic plate is fixedly installed at the lower end of each of the two movable plates. A positioning head is fixedly installed in the middle of the opposite side of each of the two magnetic plates. A strong spring is fixedly sleeved on both sides of each of the four sliding rods.

[0010] Furthermore, the two connecting blocks are respectively fixedly connected to the two electric guide rails, and the first bearing seat and the second bearing seat are rotatably connected by a rotating rod.

[0011] Furthermore, the connecting plate is slidably sleeved around the limiting rod.

[0012] Furthermore, the two movable plates are slidably sleeved around the four slide rods at their front and rear ends, respectively, and the two positioning heads are respectively engaged and installed inside the two positioning slots.

[0013] Furthermore, bearing sleeves are embedded in the middle of both sides of the furnace, and support plates are fixedly installed on both sides of the upper surface of the bottom plate near the middle.

[0014] Furthermore, handles are fixedly installed at both ends of the stirring cover on both sides, and a controller is fixedly installed in the middle of the front end face of the stirring cover.

[0015] Furthermore, a bearing pad is fixedly provided on the upper surface of the base plate near the front end, and an output nozzle is fixedly provided on the upper part of the middle of the front surface of the furnace.

[0016] This utility model has the following beneficial effects:

[0017] 1. The present invention proposes a permanent magnet stirring device for non-ferrous alloys. By setting a positioning component inside the receiving groove at the lower end of the stirring cover, the stirring cover is conveniently clamped and positioned when it is fixedly connected to the furnace, preventing the permanent magnet from being misaligned due to tilting and causing uneven stirring of the alloy, and improving the efficiency of fixing the stirring cover to the furnace.

[0018] 2. The present invention proposes a permanent magnet stirring device for non-ferrous alloys. By using a rotating component located at the rear of the upper part of the base plate, the stirred alloy inside the furnace can be easily poured out by rotating the furnace.

[0026] 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.

[0027] Reference Figures 1-5An embodiment of this utility model provides a permanent magnet stirring device for non-ferrous alloys, including a base plate 1, a rotating component 2, a furnace 5, and a stirring cover 6. A drive motor 7 is fixedly installed in the middle of the upper end face of the stirring cover 6, and a permanent magnet 15 is fixedly installed at the output end of the drive motor 7. Receiving grooves 16 are opened on both sides of the middle of the lower end face of the stirring cover 6. Positioning components 14 are fixedly installed inside the two receiving grooves 16. Magnetic strips 11 are fixedly installed on the upper sides of both sides of the furnace 5. Semicircular grooves 12 are opened in the middle of the opposite side of the two magnetic strips 11, and positioning grooves 13 are opened in the middle of the opposite side of the two semicircular grooves 12.

[0028] Bearing sleeves 17 are embedded in the middle of both sides of the furnace 5. Support plates 4 are fixedly installed on both sides of the upper surface of the bottom plate 1 near the middle. Connecting columns 18 are fixedly installed on the opposite side of the two support plates 4 near the top. Handles 8 are fixedly installed on both sides of the front and rear ends of the stirring cover 6. A controller 9 is fixedly installed in the middle of the front end of the stirring cover 6. A bearing pad 3 is fixedly installed on the upper surface of the bottom plate 1 near the front end. An output nozzle 10 is fixedly installed in the middle of the front end of the furnace 5 near the top.

[0029] Specifically, by setting a drive motor 7 on the upper surface of the stirring cover 6, the permanent magnet 15 at the output end of the drive motor 7 rotates, causing the magnetic field generated by the permanent magnet 15 to drive the melt flow. The positioning component 14 inside the receiving tank 16 facilitates the positioning and clamping of the stirring cover 6 when it is fixedly connected to the furnace 5, improving the efficiency of the fixed connection between the stirring cover 6 and the furnace 5 and preventing deviation. The magnetic strips 11 fixed on the upper sides of the furnace 5 facilitate the adsorption of the stirring cover 6 during the positioning process. The semi-circular grooves 12 on the magnetic strips 11 and the positioning grooves 13 on the semi-circular grooves 12 facilitate the positioning and clamping of the stirring cover 6 on the furnace 5 by the positioning component 14.

[0030] The bearing sleeves 17 embedded on both sides of the furnace 5 facilitate the rotation of the connecting column 18 on the support plate 4, which is then fitted inside the bearing sleeves 17. This allows for easy connection to the furnace 5 via the rotating assembly 2 on the base plate 1, enabling the furnace 5 to rotate and allowing for easy pouring of the molten metal alloy after stirring. This improves the safety and stability of the pouring process. The handles 8 located on both sides of the stirring cover 6 facilitate the handling of the stirring cover 6. The controller 9 located in the middle of the front face of the stirring cover 6 facilitates the control of the drive motor 7 and the electric push rod 1403. The bearing pad 3 at the top of the base plate 1 provides support for the container storing the molten metal alloy. The outlet 10 facilitates the orderly discharge of the molten metal alloy from the furnace 5.

[0031] Reference Figures 1-3The rotating assembly 2 includes a first bearing seat 202, a second bearing seat 204, a rotating rod 203, a fixed plate 201, a connecting plate 207, two electric guide rails 205 and a limiting rod 2010. Connecting blocks 206 are fixedly installed on the upper part of the middle of both sides of the connecting plate 207. Dampers 209 are fixedly sleeved on both the front and rear ends of the limiting rod 2010. Buffer springs 208 are fixedly installed between the two dampers 209.

[0032] Two connecting blocks 206 are fixedly connected to two electric guide rails 205 respectively. The first bearing seat 202 and the second bearing seat 204 are rotatably connected by a rotating rod 203. The connecting plate 207 is slidably sleeved around the limit rod 2010.

[0033] Specifically, the connecting blocks 206 on both sides of the connecting plate 207 facilitate the connection of the electric guide rail 205 to drive the connecting plate 207 to move. The dampers 209 fixedly sleeved around the front and rear ends of the limiting rod 2010, and the buffer springs between the dampers 209, compress the buffer springs and dampers 209 when the connecting plate 207 slides around the limiting rod 2010, so that the movement of the connecting plate 207 remains stable. The first bearing seat 202 and the second bearing seat 204 are rotatably connected by the rotating rod 203, so that the first bearing seat 202 is fixed below the furnace 5 and the second bearing seat 204 is fixed on the connecting plate 207. The movement of the connecting plate 207 drives the furnace 5 to rotate. The electric guide rail 205 and the limiting rod 2010 are both fixed on the fixed plate 201, which improves the safety of the molten metal alloy inside the furnace 5 during the pouring process after stirring, and can pour at a uniform speed, improving the efficiency of pouring the molten metal.

[0034] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 The two positioning components 14 include two movable plates 1401, four slide rods 1404 and two electric push rods 1403. The lower ends of the two movable plates 1401 are fixedly provided with magnetic plates 1405. The middle of the opposite side of the two magnetic plates 1405 is fixedly provided with positioning heads 1406. The four slide rods 1404 are fixedly sleeved with strong springs 1402 on both sides.

[0035] The two movable plates 1401 are slidably sleeved around the four slide rods 1404 at their front and rear ends, respectively, and the two positioning heads 1406 are respectively engaged and set inside the two positioning grooves 13.

[0036] Specifically, the magnetic suction plate 1405 at the lower end of the movable plate 1401 facilitates the attraction of the magnetic suction strips 11 on both sides of the upper part of the furnace 5. The positioning head 1406 in the middle of the opposite side of the magnetic suction plate 1405 facilitates the sliding within the semi-circular groove 12 and the locking within the positioning groove 13. The strong springs 1402 on both sides of the slide rod 1404 cause the movable plate 1401 to press the strong springs 1402 when sliding around the slide rod 1404. After the electric push rod 1403 pushes the movable plate 1401, the movable plate 1401 resets and the magnetic suction plate 1405 is attracted, clamped and positioned on the magnetic suction plates 1405 on both sides of the upper part of the furnace 5. This improves the positioning efficiency during the fixed connection between the furnace 5 and the stirring cover 6 and prevents the permanent magnet 15 on the stirring cover 6 from tilting, which would lead to insufficient stirring.

[0037] Working principle: During the stirring process of molten non-ferrous metal, the molten metal is poured into the furnace 5. The control handle 8 positions the stirring cover 6 above the furnace 5, causing the electric push rod 1403 in the positioning assembly 14 inside the receiving tank 16 below the stirring cover 6 to drive the moving plate 1401 to slide around the slide rod 1404 and press against the strong spring 1402. The stirring cover 6 is temporarily placed on the furnace 5, and the moving plate 1401 is reset by the strong spring 1402. The lower magnetic plate 1405 attracts and holds the magnetic strip 11 on the furnace 5. The positioning head 1406 on the magnetic plate 1405 slides on the semi-circular groove 12 and is locked inside the positioning groove 13 by moving the stirring cover 6. The stirring cover 6 is clamped and positioned with the furnace 5. The stirring cover 6 is then fixed with the furnace 5. The permanent magnet 15 at the output end of the drive motor 7 on the stirring cover 6 drives the melt flow by rotating the permanent magnet 15 and using the magnetic field generated by the permanent magnet 15 to achieve composition homogenization and grain refinement.

[0038] Next, after thoroughly stirring the molten metal alloy inside the furnace 5, the stirring cover 6 is removed, allowing the connecting blocks 206 on both sides of the connecting plate 207 in the rotating assembly 2 connected to the furnace 5 on the base plate 1 to move backward on the electric guide rail 205. The second bearing seat 204 at the front end of the connecting plate 207 is connected to the first bearing seat 202 via the rotating rod 203. The connecting column 18 on the support plate 4 rotates inside the bearing sleeves 17 on both sides of the furnace 5, causing the first bearing seat 202 to pull the furnace 5 to rotate. Furthermore, the lower end of the connecting plate 207 slides around the limit rod 2010, squeezing the buffer spring 208 and the damper 209, thus keeping the furnace 5 stable during rotation. This allows the molten metal alloy to be poured into the container through the outlet 10, improving the safety and efficiency of pouring out the stirred molten metal alloy inside the furnace 5.

[0039] 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.
