Description

Technical Field

[0001] This application relates to the field of melting equipment technology, and in particular to an alloy raw material melting equipment. Background Technology

[0002] An alloy raw material melting device is a specialized piece of equipment used to melt alloy raw materials into a liquid state. It uses heating elements to heat the alloy raw materials to their melting point, causing them to melt into a liquid state for easier subsequent processing and handling. Therefore, alloy raw material melting devices are widely used in the processing and production of various alloy materials. During the melting process, a stirring device is often used to agitate the alloy raw materials to improve melting efficiency.

[0003] When using existing alloy raw material melting devices, the alloy is quite viscous after melting, and the existing stirring devices can generally only perform local horizontal stirring, making it difficult to mix all the melted alloy from top to bottom, resulting in low melting efficiency. Therefore, an improvement is now made to an alloy raw material melting device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an alloy raw material melting device that overcomes these limitations. The device aims to solve the problem that existing alloy raw material melting devices can only perform localized horizontal stirring during the stirring process, making it difficult to mix all the molten alloy from top to bottom, resulting in low melting efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: an alloy raw material melting device, comprising a melting box, wherein a feed hopper and a discharge pipe are fixedly connected to the outer wall of the melting box near the top and bottom positions respectively, a heat insulation plate is fixedly installed inside the melting box near the top position, a rotating cylinder is rotatably connected inside the heat insulation plate via a bearing seat, a drive unit for driving the rotating cylinder is fixedly installed inside the melting box, a stirring shaft is provided inside the rotating cylinder, a stirring blade is fixedly connected to the outer wall of the stirring shaft near the lower end, a connecting block is fixedly connected to the upper end of the stirring shaft above the rotating cylinder, a rotating groove is formed inside the connecting block, a rotating block is rotatably connected inside the rotating groove, and an electric telescopic rod is fixedly installed on the upper surface of the melting box, the telescopic end of the electric telescopic rod passes through the upper cover of the melting box, inserts into the interior of the melting box, and is fixedly connected to the rotating block.

[0006] By adopting the above technical solution and setting a bearing seat, the rotating cylinder can rotate under the driving force of the drive unit. The rotation of the rotating cylinder drives the stirring shaft inside to rotate horizontally. At the same time, the stirring shaft can be vertically raised and lowered through the cooperation of the electric telescopic rod, connecting block, rotating groove and rotating block, forming a three-dimensional stirring trajectory. This movement mode can break the laminar flow state of the molten metal in the molten pool, allowing the molten alloy to be mixed from top to bottom. In addition, the up and down movement of the stirring blades can also prevent high-density metal deposition at the bottom, which helps to improve the melting efficiency.

[0007] As a preferred technical solution of this application, the driving unit includes a driving motor fixedly installed inside the melting tank, the output end of the driving motor is fixedly connected to a driving gear, a driven gear is meshed on one side of the driving gear, and the driven gear is fixedly sleeved on the outer wall of the rotating cylinder.

[0008] By adopting the above technical solution, the drive motor drives the active gear to rotate, which in turn drives the driven gear meshing with it to rotate, and the driven gear drives the rotating cylinder to rotate.

[0009] As a preferred technical solution of this application, the outer wall of the stirring shaft is fixedly connected to a limiting strip between the stirring blade and the connecting block, and the inner wall of the rotating cylinder is provided with a limiting groove, and the limiting strip slides inside the limiting groove.

[0010] By adopting the above technical solution, the sliding of the limiting strip in the limiting groove constrains the radial displacement of the stirring shaft, ensuring that it always remains vertically aligned during the lifting process, avoiding vibration or wear caused by eccentric rotation, thereby allowing the stirring shaft to rotate synchronously under the drive of the rotating cylinder.

[0011] As a preferred technical solution of this application, the external dimensions of the rotating block are adapted to the internal space dimensions of the rotating groove, and the diameter of the connecting block is larger than the diameter of the stirring shaft.

[0012] By adopting the above technical solution, the dimensions of the rotating block and the rotating groove are matched to form a constraint condition, allowing the stirring shaft to be vertically raised and lowered under the drive of the electric telescopic rod. The diameter of the connecting block must be larger than the diameter of the stirring shaft to ensure that the stirring shaft is detached from the inside of the rotating cylinder.

[0013] As a preferred technical solution of this application, the stirring shaft, the limiting strip and the stirring blade are all stainless steel components, and a gap is left between the outer wall of the stirring blade and the inner wall of the melting box.

[0014] By adopting the above technical solution, the stainless steel components have strong corrosion resistance and long service life, and the gap between the outer wall of the stirring blade and the inner wall of the melting tank ensures the safety of the device.

[0015] As a preferred technical solution of this application, a jacket is fixedly sleeved on the outer wall of the melting box near the bottom position. A hot oil inlet and a hot oil outlet are fixedly connected to the outer wall of the jacket near the top and bottom positions, respectively. The jacket is fixedly connected to the hot oil heating device through the hot oil inlet and the hot oil outlet.

[0016] By adopting the above technical solution, hot oil enters the jacket through the hot oil inlet and flows from top to bottom before being discharged from the hot oil outlet. This can fully cover the internal space of the jacket, avoid local heat accumulation, and ensure that the material in the melting box is heated evenly.

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

[0018] In this invention, by setting a bearing seat, the rotating cylinder can rotate under the driving action of the drive unit. The rotation of the rotating cylinder drives the internal stirring shaft to rotate horizontally. At the same time, the height position of the rotating block and the stirring shaft can be adjusted by the telescopic movement of the electric telescopic rod, so as to realize the vertical lifting and lowering of the stirring shaft and form a three-dimensional stirring trajectory. This movement mode can break the laminar flow state of the molten metal in the molten pool, allowing the molten alloy to be mixed from top to bottom. In addition, the up and down movement of the stirring blades can also prevent the deposition of high-density metal at the bottom, which helps to improve the melting efficiency.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1 - Figure 4 As shown, this embodiment provides an alloy raw material melting device, including a melting tank 1. A feed hopper 2 and a discharge pipe 3 are fixedly connected to the outer wall of the melting tank 1 near the top and bottom positions, respectively. A heat insulation plate 4 is fixedly installed inside the melting tank 1 near the top position. A rotating cylinder 6 is rotatably connected inside the heat insulation plate 4 via a bearing seat 5. A drive unit 7 for driving the rotating cylinder 6 is fixedly installed inside the melting tank 1. A stirring shaft 8 is provided inside the rotating cylinder 6. A stirring blade 10 is fixedly connected to the outer wall of the stirring shaft 8 near its lower end. A connecting block 11 is fixedly connected to the upper end of the stirring shaft 8 above the rotating cylinder 6. A rotating groove 12 is formed inside the connecting block 11, and the rotating block 10 is rotatably connected inside the rotating groove 12. 3. An electric telescopic rod 14 is fixedly installed on the upper surface of the melting tank 1. The telescopic end of the electric telescopic rod 14 passes through the upper cover of the melting tank 1 and is inserted into the interior of the melting tank 1 and fixedly connected to the rotating block 13. In use, the rotating cylinder 6 is driven to rotate by the drive unit 7, and the rotation of the rotating cylinder 6 drives the stirring shaft 8 inside it to rotate horizontally. At the same time, the stirring shaft 8 is vertically raised and lowered by the cooperation between the electric telescopic rod 14, the connecting block 11, the rotating groove 12 and the rotating block 13, forming a three-dimensional stirring trajectory. This movement mode can break the laminar flow state of the molten metal in the molten pool, allowing the molten alloy to be mixed from top to bottom. In addition, the up and down movement of the stirring blade 10 can also prevent the deposition of high-density metal at the bottom, which helps to improve the melting efficiency.

[0028] In this embodiment, as Figure 2 and 3 As shown, the drive unit 7 includes a drive motor 71 fixedly installed inside the melting tank 1. The output end of the drive motor 71 is fixedly connected to a drive gear 72. A driven gear 73 is meshed with one side of the drive gear 72. The driven gear 73 is fixedly sleeved on the outer wall of the rotating cylinder 6. In use, the drive motor 71 drives the drive gear 72 to rotate, thereby driving the driven gear 73 meshing with it to rotate, and the driven gear 73 drives the rotating cylinder 6 to rotate.

[0029] In this embodiment, as Figure 2-4 As shown, a limiting strip 9 is fixedly connected to the outer wall of the stirring shaft 8 between the stirring blade 10 and the connecting block 11. A limiting groove 15 is opened on the inner wall of the rotating cylinder 6. The limiting strip 9 slides inside the limiting groove 15. During use, the sliding of the limiting strip 9 in the limiting groove 15 constrains the radial displacement of the stirring shaft 8, ensuring that it always remains vertically aligned during the lifting process, avoiding vibration or wear caused by eccentric rotation, thereby allowing the stirring shaft 8 to rotate synchronously under the drive of the rotating cylinder 6.

[0030] In this embodiment, as Figure 4 As shown, the external dimensions of the rotating block 13 are adapted to the internal space dimensions of the rotating groove 12. The diameter of the connecting block 11 is larger than the diameter of the stirring shaft 8. In use, the dimensions of the rotating block 13 and the rotating groove 12 are matched to form a constraint condition, allowing the stirring shaft 8 to be vertically raised and lowered under the drive of the electric telescopic rod 14. The diameter of the connecting block 11 is larger than the diameter of the stirring shaft 8 to ensure that the stirring shaft 8 is disengaged from the inside of the rotating cylinder 6.

[0031] In this embodiment, as Figure 2 and 4 As shown, the stirring shaft 8, the limiting strip 9, and the stirring blade 10 are all stainless steel components. There is a gap between the outer wall of the stirring blade 10 and the inner wall of the melting tank 1. When in use, the stainless steel components have strong corrosion resistance and a long service life. The gap between the outer wall of the stirring blade 10 and the inner wall of the melting tank 1 ensures the safety of the device.

[0032] In this embodiment, as Figure 2 As shown, a jacket 16 is fixedly fitted onto the outer wall of the melting box 1 near the bottom. A hot oil inlet 17 and a hot oil outlet 18 are fixedly connected to the outer wall of the jacket 16 near the top and bottom, respectively. The jacket 16 is fixedly connected to the hot oil heating device through the hot oil inlet 17 and the hot oil outlet 18. In use, hot oil enters the jacket 16 through the hot oil inlet 17 and flows from top to bottom before being discharged from the hot oil outlet 18. This can fully cover the internal space of the jacket 16, avoid local heat accumulation, and ensure that the material in the melting box 1 is heated evenly.

[0033] The working principle of this utility model is as follows: When using the alloy raw material melting device of this application, alloy raw materials are added into the melting tank 1 through the feed hopper 2. Hot oil enters the jacket 16 through the hot oil inlet 17 and flows from top to bottom before being discharged from the hot oil outlet 18, which can fully cover the internal space of the jacket 16, thereby heating the alloy raw materials in the melting tank 1 to make them molten. The drive unit 7 drives the rotating cylinder 6 to rotate, and the rotation of the rotating cylinder 6 drives the stirring shaft 8 inside it to rotate horizontally. At the same time, the electric telescopic rod 14 performs telescopic movement to adjust the height position of the rotating block 13, so as to realize the vertical lifting and lowering of the stirring shaft 8 and form a three-dimensional stirring trajectory. This movement mode can break the laminar flow state of the molten metal in the molten pool, allowing the molten alloy to be mixed from top to bottom. In addition, the up and down movement of the stirring blade 10 can also prevent the deposition of high-density metal at the bottom, which helps to improve the melting efficiency.
