[0037] Reference Figure 1-Figure 3 , Figure 1 It is an assembly diagram of a partial crucible lifting device and a crucible provided by the utility model; Figure 2 It is a structural schematic diagram of a supporting device provided by the utility model; Figure 3 It is a structural schematic diagram of a crucible provided by the utility model. This embodiment provides a crucible lifting device, including a lifting device 1 and a supporting device 2 arranged relatively to each other; the supporting device 2 includes a supporting body 21, the supporting body 21 is used to carry the crucible 00, and the supporting body 21 is provided with at least two blocking members 22 on the side close to the lifting device 1, and a connecting member 23 is provided between at least two blocking members 22. The lifting device 1 drives the supporting body 21 to reciprocate along a first direction X through the connecting member 23, and the first direction X is the direction from the lifting device 1 to the supporting device 2.

[0038] Specifically, refer to Figure 1 As shown, the crucible lifting device provided in this embodiment includes a pulling device 1 and a supporting device 2 which are arranged relatively to each other. The pulling device 1 is connected to a heavy hammer (not shown in the figure) in the single crystal furnace on the side away from the supporting device 2. When the single crystal furnace is running, the heavy hammer is hung on the lower end of the suspension wire clamp or the jumper wire. The heavy hammer can be connected to the seed crystal chuck. The seed crystal chuck is pulled by the heavy hammer to complete the work of pulling the single crystal. The heavy hammer is suitable for high temperature environment and can play a role of stabilizing verticality during the crystal pulling process. The heavy hammer is a structure inside the single crystal furnace. The heavy hammer can match the mechanical action of the single crystal furnace table. Similarly, other structures connected to the heavy hammer can also match the mechanical action of the single crystal furnace table. Since the pulling device 1 is connected to the heavy hammer on the side away from the supporting device 2, the control system of the single crystal furnace is manually operated (not shown in the figure). (as shown) controlling the movement of the weight can control the movement of the pulling device 1, the weight drives the pulling device 1 to reciprocate along the first direction X, the first direction X is the direction from the pulling device 1 to the supporting device 2, it can be understood that the control system in the single crystal furnace has crystal lifting and crystal lowering instructions, when the crystal lifting instruction is started, the weight drives the pulling device 1 to rise in the first direction X, when the crystal lowering instruction is started, the weight drives the pulling device 1 to fall in the first direction X; the crucible lifting device provided in this embodiment connects the pulling device 1 with the weight, and can directly use the lifting control system of the single crystal furnace table to control the movement of the pulling device 1. Compared with other mechanical devices for removing the crucible, it can avoid the use of other transmission mechanisms, reduce process costs, and reduce safety hazards and labor costs.

[0039] Combination Figure 1-Figure 3As shown, the support device 2 includes a support body 21, and the support body 21 is used to support the crucible 00. It can be understood that the support body 21 is located on the side of the crucible 00 away from the pulling device 1, wherein the crystal pulling process is as follows: polycrystalline silicon and other silicon raw materials are placed in a crucible, and the silicon raw materials are melted by a heater in a single crystal furnace, and a seed crystal fixed on the seed crystal axis is inserted into the melt surface. After the seed crystal and the melt are fully melted, the seed crystal is slowly pulled upward, and the crystal grows at the lower end of the seed crystal to eventually form a crystal rod. The crucible 00 is a structure that supports the crucible in the single crystal furnace. The shape of the crucible 00 is approximately a bottomless circular bowl-shaped structure. The crucible 00 has an R angle, and the R angle is the part with an arc surface at the bottom of the crucible 00. The support device 21 can clamp the R angle of the crucible 00, and the support body 21 is close to the side of the pulling device 1 At least two blocking members 22 are provided, and a accommodating cavity (not marked in the figure) for accommodating the crucible 00 is formed between the at least two blocking members 22 and the supporting body 21. The blocking member 22 can limit the crucible 00 and lock the crucible 00 to prevent it from falling from the supporting body 21, thereby eliminating safety hazards. A connecting member 23 is provided between the at least two blocking members 22, and the connecting member 23 can be a rope-like structure. When the supporting body 21 carries the crucible 00, the lifting device 1 pulls the connecting member 23, and the heavy hammer can drive the connecting member 23 to reciprocate along the first direction X. Since the connecting member 23 is fixedly connected to the blocking member 22, the lifting device 1 can drive the supporting body 21 to reciprocate along the first direction X through the connecting member 23. The first direction X is the direction from the lifting device 1 to the supporting device 2.

[0040] Reference Figure 2 As shown, the material of the lifting device 1, the supporting body 21 and the blocking member 22 can be selected from metal materials, and the metal material can be stainless steel. Stainless steel has the advantages of corrosion resistance, high temperature resistance, light weight, long service life, easy cleaning, etc.; the connecting member 23 can be selected from steel wire rope, which has the advantages of being able to transmit loads over long distances, having a large load-bearing safety factor, being safe and reliable to use, having a light weight, having high tensile strength, fatigue strength and impact toughness, good corrosion resistance, and good softness; it should be noted that the materials that can be selected for the lifting device 1, the supporting body 21, the blocking member 22 and the connecting member 23 include but are not limited to these, and are not limited here.

[0041] Reference Figure 1As shown, the crucible lifting device provided in this embodiment is applied to a single crystal furnace. The heat field diameter of the single crystal furnace includes but is not limited to 36 inches. The size of the crucible lifting device can be adaptively adjusted with parameters such as the heat field diameter and the size of the crucible 00, which are not limited here. After the single crystal furnace performs crystal pulling operation, there are remaining crucibles in the single crystal furnace. Through the crucible lifting device, the crucible 00 can be lifted and pulled by relying on a heavy hammer, so that the crucible 00 can be dismantled. The crucible lifting device provided in this embodiment has the advantages of increasing the safety of the dismantling work of the crucible 00 and reducing labor costs. It should also be noted that the crucible lifting device provided in this embodiment can be used to lift crucibles, insulation cylinders and other heat field materials in addition to lifting the crucible 00, which is not limited here.

[0042] Compared with the prior art, the Crucible Lifting Device provided in this embodiment achieves at least the following beneficial effects:

[0043] The crucible lifting device provided in this embodiment includes a pulling device and a supporting device which are relatively arranged; the supporting device includes a supporting body, the supporting body is used to carry the crucible, at least two blocking members are arranged on the side of the supporting body close to the pulling device, a connecting member is arranged between at least two blocking members, the pulling device drives the supporting body to reciprocate along a first direction through the connecting member, and the first direction is the direction from the pulling device to the supporting device; the above scheme is adopted to avoid the additional installation of other transmission structures, and the lifting and lifting of the crucible can be completed directly by using the control lifting device of the single crystal furnace table, which is convenient to use, reduces the process difficulty, and reduces safety hazards, while increasing the safety of the crucible dismantling work while saving labor costs.

[0044] In an optional embodiment, the support body 21 includes an inner surface 211, the inner surface 211 is in contact with the crucible 00, and along the first direction X, the inner surface 211 is inclined toward the center of the support body 21 away from the side of the pulling device 1.

[0045] Specifically, combined Figure 2-Figure 3 As shown, the support body 21 includes an inner surface 211, and the inner surface 211 is a surface that contacts the R angle of the Crucible 00. The inner surface 211 is in contact with the Crucible 00. Along the first direction X, the inner surface 211 is inclined toward the center of the support body 21 away from the side of the pulling device 1. It can be understood that the inner surface 211 has an inclined surface. This arrangement can make the inner surface 211 more match the structure of the bottom of the Crucible 00, thereby avoiding damage to the Crucible 00 and affecting the lifting of the Crucible 00 due to the incompatibility of the structures.

[0046] In an optional embodiment, the support body 21 is an annular structure, and at least two blocking members 22 are arranged along the diameter direction of the support body 21 .

[0047] Specifically, combined Figure 1-Figure 2As shown, since the cross-sectional figure of the Crucible 00 along the first direction X is circular, the support body 21 is set as a ring structure, which can ensure that the support body 21 is in contact with the Crucible 00 as much as possible, so that the support body 21 can support the Crucible 00 from 360°, thereby improving the supporting effect of the support body 21 and balancing the supporting force exerted on the Crucible 00. At the same time, the setting of the ring structure can save the cost of manufacturing the support body 21 while ensuring the supporting effect of the support body 21, thereby avoiding waste of resources.

[0048] Combination Figure 2-Figure 3 As shown, at least two blocking members 22 are arranged along the diameter direction of the support body 21. This arrangement can ensure that when the connecting member 23 drives the blocking member 22 to lift, the force on the support body 21 is balanced and uniform, thereby preventing the support body 21 from shaking due to uneven force, causing safety hazards; optionally, the number of blocking members 22 can be four, and the arc lengths between each two adjacent blocking members 22 are equal. Setting four blocking members 22 can make the force on the support body 21 more uniform, facilitate stabilizing the crucible 00, and prevent the crucible 00 from falling from the support body 21; as long as the effects of stabilizing the crucible 00, limiting the position of the crucible 00, and preventing the crucible 00 from falling from the support body 21 can be achieved, the number of blocking members 22 can be adaptively adjusted according to actual conditions, and this embodiment does not make any specific restrictions on this.

[0049] In an optional embodiment, the inner diameter of the support body 21 on the side close to the lifting device 1 is larger than the inner diameter of the support body 21 on the side away from the lifting device 1 .

[0050] Specifically, combined Figure 2-Figure 3 As shown, the inner diameter of the support body 21 close to the lifting device 1 is set to be larger than the inner diameter of the support body 21 away from the lifting device 1, also to ensure that along the first direction X, the inner surface 211 away from the lifting device 1 is inclined toward the center of the support body 21 (that is, the inner surface 211 has an inclined surface). This setting can make the inner surface 211 more matched with the structure of the bottom of the Crucible 00, avoiding damage to the Crucible 00 and affecting the lifting of the Crucible 00 due to the incompatibility of the structures.

[0051] Optionally, the inner diameter of the support body 21 is gradually changed from the inner diameter on the side close to the pulling device 1 to the inner diameter on the side away from the pulling device 1. For example, the inner diameter changes gradually. This arrangement can make the inner surface 211 more matched with the structure of the bottom of the Crucible 00, thereby avoiding damage to the Crucible 00 and affecting the lifting of the Crucible 00 due to structural incompatibility between the two, thereby further improving the supporting effect of the support body 21.

The two C-shaped structures can be combined into a circular ring structure. The first support portion 21a and the second support portion 21b can be arranged in a mirror-symmetrical manner, and the straight line where the symmetry axes of the first support portion 21a and the second support portion 21b are located coincides with the straight line where a diameter of the circular ring structure is located; the first support portion 21a and the second support portion 21b have the same structure, and the first support portion 21a and the second support portion 21b can be made of the same process and the same The first supporting part 21a and the second supporting part 21b having the same structure can ensure that the supporting force applied to the crucible 00 is more uniform when supporting the crucible 00, thereby avoiding the displacement of the crucible 00 when the lifting device 1 drives the supporting body 21 to reciprocate along the first direction X through the connecting piece 23. At the same time, since the force is mutual, the supporting forces applied to the crucible 00 by the first supporting part 21a and the second supporting part 21b can make the force on the crucible 00 more uniform.
