[0029] In the description of the present invention, it should be understood that terms such as "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0030] Embodiment 1

[0031] like Figure 1 and Figure 2 As shown: the utility model provides a lifting and cooling structure for a furnace body, comprising a fixed bracket 1, a cooling furnace body 2 installed on the top of the fixed bracket 1, a lower furnace body 3, a vertical lifting assembly 9 and a slide rail 6 for cooperating with a pulley 52; wherein a cooling assembly 4 is arranged inside the cooling furnace body 2; a crucible 8 with a temperature sensor 81 and a crucible lifting assembly 7 for driving the crucible 8 to move up and down are arranged inside the lower furnace body 3, a moving base 5 is arranged at the bottom of the lower furnace body 3, the crucible 8 passes through the cooling assembly 4, and pulleys 52 are installed on both sides of the moving base 5; the vertical lifting assembly 9 is installed on the fixed bracket 1, and both sides of the moving base 5 are clamped with the vertical lifting assembly 9; the slide rail 6 is arranged on the ground directly below the lower furnace body 3.

[0032] The cooling assembly 4 includes a cooling tube 41 wound into a cylindrical shape and installed in the middle of the cooling furnace body 2, and a cooling barrel 42 arranged inside the cooling tube 41. The cooling barrel 42 is a hollow columnar structure, and the outer surface of the cooling barrel 42 is in contact with the cooling tube 41. The diameter of the crucible 8 is smaller than the diameter of the cooling barrel 42 and passes through the interior of the cooling barrel 42.

[0033] In this embodiment, when heating, the heating zone, the cooling furnace body and the lower furnace body are integrated, wherein the lower furnace body is fixedly mounted at the bottom of the cooling furnace body by a snap lock 21; in specific use, after the material in the crucible is heated in the heating zone, the crucible 8 is lowered into the cooling assembly 4 in the cooling furnace body 2 by the crucible lifting assembly 7, and then after cooling, the cooling furnace body 2 is separated from the lower furnace body 3, and then the vertical lifting assembly 9 drives the moving base 5 and the lower furnace body 3 thereon to descend, and the crucible 8 is separated from the cooling assembly 4, and when the moving base 5 descends, the pulley 52 thereon will be released from the slide rail 6, and then the moving base 5 is separated from the vertical lifting assembly 9, and the moving base 5 moves on the slide rail 6, and the crucible containing the cooled finished product is removed for the next processing. In this solution, the furnace body is divided into different areas, and heating and cooling can be achieved in the furnace body, and rapid cooling can be achieved, which greatly reduces the processing time and improves efficiency.

[0034] At the same time, in this embodiment, the design of the cooling assembly 4 ensures the efficiency and uniformity of the crucible 8 during the cooling process. The two ends of the cooling pipe 41 are respectively connected to the circulation pump, and the cooling pipe 41 is wound into a cylindrical shape. This design enables the cooling medium (such as water or coolant) to form a uniform cooling environment when flowing in the pipe. The cooling pipe 41 and the cooling barrel 42 are both made of materials with high thermal conductivity to optimize the cooling efficiency.

[0035] The cooling barrel 42 is a core part of the cooling assembly 4, and is in the shape of a hollow columnar structure, which is in close contact with the cooling tube 41. The outer surface of the cooling barrel 42 is closely fitted with the inner wall of the cooling tube 41 to form a closed cooling space. When the cooling medium flows in the cooling tube 41, it will take away the heat of the cooling barrel 42, thereby reducing the temperature of the crucible 8 and the molten metal therein.

[0036] Since the diameter of the crucible 8 is smaller than that of the cooling barrel 42, the crucible 8 can easily pass through the interior of the cooling barrel 42. This design allows the exterior of the crucible 8 to completely contact the inner wall of the cooling barrel 42 during the descent process, thereby achieving all-round cooling. At the same time, the hollow structure of the cooling barrel 42 also ensures the uniformity and stability of the cooling effect.

[0037] In actual operation, the cooling medium enters through the inlet of the cooling tube 41, flows in the tube and takes away the heat, and then is discharged from the outlet. This circulating cooling method can continuously reduce the temperature of the crucible 8 and the molten metal inside until the desired cooling effect is achieved.

[0038] In addition, the lifting and cooling structure in this embodiment also realizes the smooth lifting and lowering of the lower furnace body 3 and the crucible 8 through the cooperation of the vertical lifting assembly 9 and the slide rail 6. This design enables the crucible 8 to adjust its position as needed during the cooling process, further optimizing the cooling effect. At the same time, through the real-time monitoring of the temperature sensor 81 and the precise control of the control system, it can ensure that the molten metal is cooled and solidified within a suitable temperature range, thereby improving the quality and production efficiency of the product.

[0039] Embodiment 2

[0040] Based on the first embodiment, the difference of this embodiment is that:

[0041] like Figure 2-5 As shown: the crucible lifting assembly 7 includes a fixed plate 76, a lifting mechanism and a lifting bracket, wherein the crucible 8 is mounted on the top of the fixed plate 76; the lifting mechanism includes a telescopic rod 74 and a lifting cylinder 72 that drives the telescopic rod 74 to move up and down, and the fixed plate 76 is mounted on the top of the telescopic rod 74; the lifting mechanism is mounted on the lifting bracket, and the bottom of the lifting bracket is fixedly connected to the inner wall of the lower furnace body 3. The lifting bracket includes two parallel mounting plates 71, a guide sleeve 73 is arranged between the two mounting plates 71, and a plurality of guide rods 75 are installed in the guide sleeve 73, and the top of the guide rod 75 is fixedly connected to the bottom of the fixed plate 76. A heat insulation felt 77 is arranged on the top of the fixed plate 76.

[0042] In this embodiment, the crucible lifting assembly 7 is tightly connected to the crucible 8 via the fixing plate 76, thereby ensuring the stability and safety of the crucible 8 during the lifting process.

[0043] The lifting mechanism, as the core part of the crucible lifting assembly 7, adopts a combination of a telescopic rod 74 and a lifting cylinder 72. The top of the telescopic rod 74 is connected to the fixed plate 76. Driven by the lifting cylinder 72, the telescopic rod 74 can move up and down smoothly, thereby driving the crucible 8 to achieve the lifting function. This design is not only simple in structure, but also easy to operate, and can quickly complete the lifting action of the crucible 8.

[0044] The design of the lifting bracket further enhances the stability and reliability of the crucible lifting assembly 7. The two parallel mounting plates 71 provide a stable support for the lifting mechanism. The combination of the guide sleeve 73 and the guide rod 75 ensures the stability and linearity of the telescopic rod 74 during the lifting process, avoiding safety hazards caused by deviation or shaking.

[0045] In addition, the heat insulation felt 77 disposed on the top of the fixing plate 76 effectively isolates the heat conduction between the crucible 8 and the fixing plate 76 .

[0046] In practical applications, the operator can precisely control the lifting cylinder 72 through the control system to achieve smooth lifting of the crucible 8. At the same time, through real-time monitoring by the temperature sensor 81, it can be ensured that the temperature of the molten metal is controlled within a suitable range during the cooling process. This intelligent control method not only improves work efficiency, but also ensures the stability of product quality.

[0047] In summary, the crucible lifting assembly 7 in this embodiment achieves stable lifting and precise control of the crucible 8 through optimized design and intelligent control, thereby improving work efficiency and product quality. This innovative design has brought important technical breakthroughs to the metal smelting and cooling process.

[0048] Embodiment 3

[0049] Based on the first embodiment, the difference of this embodiment is that:

[0050] like Figure 1 , Figure 6-Figure 9 As shown: the vertical lifting assembly 9 includes a guide rod, a sliding block 91 installed on the guide rod, and a lifting motor that drives the sliding block 91 to move up and down. A fixed block 911 is arranged on the front side of the sliding block 91, a buffer pin 912 is installed on the fixed block 911, a clamping block 914 is arranged on the top of the buffer pin 912, the clamping block 914 is provided with a plurality of clamping holes 915, a spring 913 is arranged on the outer sleeve of the buffer pin 912, and both ends of the spring 913 are fixedly connected to the bottom of the clamping block 914 and the top of the fixed block 911 respectively.

[0051] The movable base 5 includes a chassis 51, a support rod installed on the top of the chassis 51, and a driving motor 53 that drives the pulley 52 to rotate. The top of the support rod is fixedly connected to the bottom of the lower furnace body 3. Snap-in plates 54 are installed on both sides of the chassis 51, and snap-in rods 541 that match the snap-in holes 915 one by one are installed on the snap-in plates 54.

[0052] In this embodiment, the vertical lifting assembly 9 drives the mobile base 5 to move up and down, and the mobile base 5 is fixed to the sliding block 91 through the clamping plates 54 installed on both sides of the chassis 51. Specifically, the clamping rod 541 on the clamping plate 54 is inserted into the clamping hole 915 on the clamping block 914 to fix it. When the vertical lifting assembly 9 descends, the pulley 52 contacts the slide rail 6, and then the slide block 91 continues to move downward, the clamping rod 541 disengages from the clamping hole 915, and then the driving electrode 53 is started to drive the pulley to move on the slide rail 6, thereby removing the cooled crucible for the next step of operation. This setting realizes automatic detachment and automatic removal of the crucible, saving manpower and material resources.
