Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, and in particular relates to a high-efficiency stirring device for lead alloy smelting furnaces. Background Technology

[0002] In lead alloy smelting, the stirring device plays a crucial role, directly affecting smelting efficiency, energy consumption, and the quality of the final product. During lead alloy smelting, mixing efficiency determines the uniformity of alloy composition and microstructure distribution, as well as the smelting speed. Inefficient stirring leads to uneven melting, affecting product quality and even requiring additional mixing and adjustment steps, increasing system energy consumption and production costs. Traditional stirring methods inevitably produce uneven melt mixing, resulting in circulation and other ineffective energy consumption. Especially in large-scale production, excessively high energy costs constitute a significant portion of production costs. Developing efficient and low-energy-consumption stirring devices is crucial for reducing production costs.

[0003] A prior art example, Chinese Patent (CN208313075U), discloses a stirring device for a smelting furnace, which includes a hydraulic lifting mechanism. A lower support plate is mounted on the top of the hydraulic lifting mechanism, and a slide rail is provided on the upper side of the lower support plate. An upper slide plate is slidably connected above the slide rail. A lead screw is connected to one end of the upper slide plate, and a stirring device is mounted on the other end. A drive device is mounted above the upper slide plate to drive the stirring device to rotate. In use, the lead screw pushes the upper slide plate to slide along the slide rail, allowing the stirring device to extend into the smelting furnace. The hydraulic lifting mechanism adjusts the height of the stirring device, causing it to extend into the molten metal. The drive device then drives the stirring device to rotate, thus stirring the molten metal.

[0004] The device has the following defects: First, the stirring center cannot be moved, resulting in low mixing efficiency; second, the stirring angle cannot be adjusted, resulting in poor mixing effect and uneven distribution of alloy composition; third, the stirring blades cannot be adjusted in position, which cannot meet the stirring position required for different metal densities, resulting in low applicability of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] like Figures 1 to 3 As shown, the prior art in this embodiment has the following problems: The inventors have found the following defects in the prior art: 1. The stirring center cannot be moved, resulting in low mixing efficiency; 2. The stirring angle cannot be adjusted, resulting in poor mixing effect and uneven distribution of alloy composition; 3. The stirring blades cannot be adjusted in position, and cannot cope with the stirring position that needs to be adjusted for different metal densities, resulting in low applicability of the device.

[0024] Therefore, the inventor provides a high-efficiency stirring device for a lead alloy smelting furnace, including a stirring device body and a controller 1. The controller 1 is located on the right side of the smelting furnace 2 and is electrically connected to the stirring device body. The stirring device body also includes an adjustment platform, a stirring rod rotating device, and a blade movable stirring rod. The adjustment platform is located above the smelting furnace 2, and the stirring rod rotating device is located below the adjustment platform. The front end of the adjustable blade stirring rod is connected to the end of the stirring rod rotating device.

[0025] By adopting the above scheme, the controller 1 can control the adjustment platform to adjust the overall position of the stirring device, and the control device for rotating the stirring rod can control the rotation of the adjustable blade stirring rod, changing the stirring center and stirring angle, increasing the mixing efficiency and enhancing the mixing effect. By controlling the movable blade stirring rod through the controller 1, the position of the blade 15 on the stirring rod can be changed. The threaded connection between the connecting rod 14 and the blade 15 is detachable and the stirring position can be adjusted up and down, improving the applicability of the device. The overall stirring efficiency of the device is high, the time consumption is short, and the energy-saving benefits are good.

[0026] Furthermore, the movable stirring rod also includes a stirring motor 10, a small sleeve 11, a large sleeve 12, a telescopic electric cylinder 13, a connecting rod 14, blades 15, a rotating motor 16, a gear shaft b17, and a rotating gear 18. The output end of the stirring motor 10 is connected to the front end of the small sleeve 11. The outer side of the middle part of the small sleeve 11 is slidably connected to the inner side of the front end of the large sleeve 12. The upper inner side of the small sleeve 11 is provided with a telescopic electric cylinder 13. The front end of the connecting rod 14 is connected to the side of the telescopic rod of the telescopic electric cylinder 13. The blades 15 are installed at the end of the connecting rod 14. The rotating motor 16 is located on the side of the top end of the small sleeve 11. The output end of the rotating motor 16 is connected to the gear shaft b17. The rotating gear 18 is located on the outer side of the front end of the large sleeve 12 and meshes with the gear shaft b17.

[0027] The telescopic electric cylinder 13 can drive the connecting rod 14 and the blade 15 to extend and retract outside the small sleeve 11. The rotating motor 16 drives the rotating gear 18 through the gear shaft b17 to make the large sleeve 12 rotate outside the small sleeve 11, thereby adjusting the vertical position of the connecting rod 14 and the blade 15 on the telescopic rod of the telescopic electric cylinder 13 on the large sleeve 12, thus improving the applicability of the device.

[0028] Furthermore, a circular hole (not shown in the figure) is provided at the bottom of the large sleeve 12.

[0029] Since the large sleeve is equipped with an adjustment groove 19, the alloy solution will enter from the side. Therefore, a round hole is provided to facilitate the discharge of the alloy molten liquid inside the large sleeve 12 from the bottom, so as to prevent the alloy molten liquid from accumulating in the large sleeve 12 during the stirring process.

[0030] Furthermore, an adjustment groove 19 is provided on the outer side of the large sleeve 12;

[0031] The adjustment groove 19 allows the connecting rod 14 and the blade 15 to be adjusted to different positions by rotating the motor 16.

[0032] Furthermore, a limit hole 20 is provided at the end of the adjusting groove 19;

[0033] The limiting hole 20 can fix the connecting rod 14 to prevent the connecting rod 14 from shifting after the position is changed. Example 1

[0034] like Figures 1 to 3 As shown;

[0035] Furthermore, the adjustment platform also includes an X-axis lead screw guide rail 3, a Y-axis lead screw guide rail 4, an X-axis slider 5, and a Y-axis slider 6. The X-axis lead screw guide rail 3 is respectively set on both sides above the melting furnace 2. The X-axis slider 5 is slidably mounted on the X-axis lead screw guide rail 3. The Y-axis lead screw guide rail 4 is set on the X-axis slider 5. The Y-axis slider 6 is slidably mounted on the Y-axis lead screw guide rail 4.

[0036] The X-axis lead screw guide 3 drives the X-axis slider 5 to move the Y-axis lead screw guide 4 on the X-axis. The Y-axis lead screw guide 4 can drive the Y-axis slider 6 to move in the Y-axis direction, so that the entire adjustment platform can be adjusted and moved in the X and Y axes. This can change the stirring center and improve the mixing efficiency. At the same time, this method can precisely adjust the position of the stirring center.

[0037] Furthermore, the stirring rod rotating device also includes a rotating mechanical joint 7, a spherical mechanical joint 8, and a stirring rod support 9. The rotating mechanical joint 7 is located below the Y-axis slider 6, the spherical mechanical joint 8 is located below the rotating mechanical joint 7, and the stirring rod support 9 is located below the spherical mechanical joint 8.

[0038] Among them, the rotating mechanical joint 7 can rotate horizontally, and the spherical mechanical joint 8 can drive the stirring rod support 9 to swing on the Z-axis plane. The combination of the rotating mechanical joint 7 and the spherical mechanical joint 8 can realize the change of the angle of the device, thereby changing the stirring angle and improving the mixing efficiency. Example 2

[0039] Not shown in the diagram;

[0040] Furthermore, the connecting rod 14 and the blade 15 are threaded together;

[0041] The threaded connection facilitates the disassembly of the connecting rod 14 and the blade 15.

[0042] In summary, the device includes a stirring device body and a controller 1. The adjustment platform and stirring rod can change the stirring center and adjust the stirring angle, thereby increasing the mixing efficiency and enhancing the mixing effect. The movable stirring rod with blades can adjust the position of the stirring blades 15, and the blades 15 are detachable, which improves the applicability of the device.

[0043] The working principle of this utility model is as follows: Using the scheme of embodiment 1, the controller 1 controls the X-axis slider 5 to slide synchronously on the X-axis lead screw guide 3, thereby driving the Y-axis lead screw guide 4 on the X-axis slider 5 to change its position in the X-axis direction. At the same time, the controller can control the Y-axis lead screw guide 4 to change the position of the Y-axis slider 6 in the Y-axis direction. In this way, the stirring rod rotating device set below the Y-axis slider 6 can move in the X and Y-axis directions, which can change the stirring center and improve the mixing efficiency. At the same time, this method can precisely adjust the position of the stirring center.

[0044] By controlling the horizontal rotation of the rotary mechanical joint 7 through the controller 1, and cooperating with the spherical mechanical joint 8 to swing on the Z-axis plane, the movable stirring rod with blades set below can be driven to rotate, thus changing the stirring angle and improving the mixing efficiency.

[0045] The controller 1 controls the movable stirring rod with blades at the end of the spherical rotating shaft 16 to start. The stirring motor 10 drives the small sleeve 11 below and the rotating motor 16 to rotate, which, together with the blades 15, realizes the basic stirring function. At this time, the connecting rod 14 is stuck in the limiting hole 20 on the large sleeve 12. When the position of the blades 15 needs to be adjusted, the telescopic electric cylinder 13 retracts, so that the connecting rod 14 moves upward away from the limiting groove. The rotating motor 16 starts, drives the gear shaft b17 to rotate, so that the rotating gear 18 drives the large sleeve 12 to rotate to the right, so that the connecting rod 14 comes to the vertical section of the adjustment groove 19. Then the telescopic electric cylinder 13 retracts or extends to adjust the connecting rod 14 to another position. At the same time, the large sleeve 12 rotates back to the top of the limiting groove, and the telescopic electric cylinder 13 extends downward to lock the connecting rod 14 into the limiting groove, thus completing the switching of the position of the blades 15 and improving the applicability of the device.

[0046] The scheme of Embodiment 2 is adopted, in which the connecting rod 14 and the blade 15 are threadedly connected, which makes it easy to remove and replace the blade 15, improves the applicability of the device, and the overall stirring efficiency of the device is high, the time is short, and the energy-saving benefits are good.

[0047] This completes the operation of the entire mixing device.
