[0031] As Figures 1 to 3 According to a first aspect of the present application, a quick dismounting tool for a single crystal furnace is provided, which includes a hook portion 2 and a pulling rod main body 1.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the above components of the quick dismounting tool for a single crystal furnace and the connection relationship of the above components will be described in detail.

[0033] As Figures 1 to 3As shown in the embodiment, the hook part 2 can be installed on the inner wall of the middle furnace cylinder 3 of the single crystal furnace. The pulling rod body 1 can be arranged inside the single crystal furnace. The middle part of the pulling rod body 1 can be clamped on the hook part 2, and the bottom end of the pulling rod body 1 can be clamped on the base plate 4 of the single crystal furnace. In this way, the middle furnace cylinder 3 and the base plate 4 of the single crystal furnace can be connected together through the pulling rod body 1. When the operator lifts the middle furnace cylinder 3, the base plate 4 will be lifted together with the pulling rod body 1, and the base plate 4 can support the heat preservation cylinder, thereby reducing the components that need to be disassembled, and achieving the purpose of quickly disassembling the hot field.

[0034] Preferably, as Figures 1 to 3 As shown in the embodiment, the pulling rod body 1 can include an upper pulling rod 11 and a lower pulling rod 12. The upper pulling rod 11 can be clamped on the hook part 2, that is, the upper pulling rod 11 is clamped on the inner wall of the middle furnace cylinder 3. The bottom end of the lower pulling rod 12 can be clamped on the base plate 4, that is, the lower pulling rod 12 is clamped on the base plate 4. The top end of the lower pulling rod 12 and the bottom end of the upper pulling rod 11 are detachably connected, so that the pulling rod body 1 can be disassembled according to actual needs, and the total length of the pulling rod body 1 can be adjusted by adjusting the distance between the upper pulling rod 11 and the lower pulling rod 12.

[0035] Further, preferably, as Figures 1 to 3 As shown in the embodiment, the pulling rod body 1 can further include a threaded connector 10. The threaded connector 10 can be arranged between the bottom end of the upper pulling rod 11 and the top end of the lower pulling rod 12. The threaded connector 10 can be provided with an internal threaded hole. The bottom end of the upper pulling rod 11 and the top end of the lower pulling rod 12 can be provided with external threads. The bottom end of the upper pulling rod 11 and the top end of the lower pulling rod 12 can be connected to the two ends of the threaded connector 10, respectively, so as to connect the upper pulling rod 11 and the lower pulling rod 12. When it is necessary to adjust the length of the pulling rod body 1, the operator can adjust the distance between the upper pulling rod 11 and the lower pulling rod 12 by screwing the threaded structure.

[0036] Specifically, as Figure 2As shown in the embodiment, the threaded connection 10 can include an upper ring body 101, a lower ring body 102, and a plurality of connecting blocks 103. The upper ring body 101 can be formed with an internally threaded hole. The bottom end of the upper lifting rod 11 can be disposed in the upper ring body 101 and threadedly connected with the upper ring body 101. The lower ring body 102 can be coaxially arranged with the upper ring body 101. The lower ring body 102 can be formed with an internally threaded hole. The top end of the lower lifting rod 12 can be disposed in the lower ring body 102 and threadedly connected with the lower ring body 102. The plurality of connecting blocks 103 can be arranged between the upper ring body 101 and the lower ring body 102. The two ends of the connecting block 103 can be respectively welded to the bottom surface of the upper ring body 101 and the top surface of the lower ring body 102. The plurality of connecting blocks 103 can be arranged at intervals in the circumferential direction, and the top end of the lower lifting rod 12 and the bottom end of the upper lifting rod 11 are located between the plurality of connecting blocks 103.

[0037] Preferably, as shown in the embodiment, Figure 1 and Figure 2 As shown in the embodiment, in the upper lifting rod 11, a circular ring-shaped lifting head 13 can be installed. The inner surface of the lifting head 13 can be formed with an internal thread, and the outer surface of the upper lifting rod 11 can be provided with an external thread. The lifting head 13 can be threadedly connected with the upper lifting rod 11, so that the lifting head 13 can move along the axial direction of the upper lifting rod 11 to adjust the position of the lifting head 13.

[0038] Further, preferably, as shown in the embodiment, Figures 1 to 3 The hook portion 2 can include a hook body 21 and a clamping groove 22. The outer shape of the hook body 21 can be approximately cuboid. One side of the hook body 21 is fixed to the inner wall of the middle furnace cylinder 3, and the specific installation height of the hook body 21 can be adaptively changed according to actual needs. The side of the hook body 21 away from the middle furnace cylinder 3 is provided with an open slot 210. The open slot 210 can pass through the hook body 21 in the vertical direction, and the width of the open slot 210 is greater than the diameter of the upper lifting rod 11. The upper lifting rod 11 is disposed in the hook body 21 in the vertical direction through the open slot 210. In addition, a clamping groove 22 can also be provided at the top of the hook body 21. The clamping groove 22 can be a circular groove, and the diameter of the clamping groove 22 is greater than the width of the open slot 210. The lifting head 13 can be clamped in the clamping groove 22. The upper lifting rod 11 is disposed in the clamping groove 22, and the diameter of the lifting head 13 is less than the open slot 210. In this way, when the operator lifts the middle furnace cylinder 3, the hook can exert an upward force on the lifting head 13, thereby lifting the upper lifting rod 11 upward.

[0039] Further preferably, as shown in the embodiment, Figure 1 and Figure 2As shown in the embodiments, the quick dismounting tool for the single crystal furnace can further comprise a middle wrench 130. Specifically, the middle wrench 130 can be a ring-shaped outer hexagonal wrench. The upper pull rod 11 can be arranged in the middle wrench 130. An inner hexagonal slot 22 can be arranged at the top of the pull head 13, so that the middle wrench 130 can be partially arranged in the slot 22, thereby facilitating the operator to rotate the pull head 13 to adjust the position of the pull head 13 on the upper pull rod 11.

[0040] In addition, preferably, as shown in the embodiments, Figure 1 and Figure 2 As shown in the embodiments, the base plate 4 can be provided with a through hole at the position corresponding to the hook, the through hole penetrating the base plate 4 in the vertical direction, and the diameter of the through hole is greater than the diameter of the lower pull rod 12. Thus, the lower pull rod 12 can be arranged in the base plate 4 through the through hole. A rod-shaped lower wrench 121 can be arranged at the bottom end of the lower pull rod 12. Preferably, the extension direction of the lower wrench 121 is perpendicular to the axial direction of the lower pull rod 12, and the length of the lower wrench 121 is greater than the hole diameter of the through hole. In this way, when the lower pull rod 12 is lifted, the lower wrench 121 will abut against the base plate 4, thereby lifting the base plate 4.

[0041] Preferably, as shown in the embodiments, Figure 1 and Figure 2 As shown in the embodiments, the top end of the upper pull rod 11 can be provided with a rod-shaped upper wrench 111. The extension direction of the upper wrench 111 is perpendicular to the axial direction of the upper pull rod 11. The upper pull rod 11 is used for the operator to grasp and rotate. Preferably, the upper wrench 111 can be higher than the top end of the middle furnace cylinder 3, so as to facilitate the operator to operate and provide sufficient adjustment space for the pull head 13.

[0042] In addition, as shown in the embodiments, Figure 1 According to the second aspect of the present application, a single crystal furnace is provided, which comprises the quick dismounting tool for the single crystal furnace as described above.

[0043] In use, the quick dismounting tool for the single crystal furnace can complete the dismounting and mounting of the main components of the hot field within 30 minutes. Compared with the traditional method, the quick dismounting tool for the single crystal furnace shortens the dismounting and mounting time by at least 80%. Under the premise of meeting the quick dismounting and mounting function, the quick dismounting tool for the single crystal furnace can ensure the stability and reliability of the hot field structure during the single crystal production process, control the deformation of the key parts of the hot field within ±0.1mm, and ensure the stability of the single crystal growth.

[0044] When the bottom hot zone 6 needs to be cleaned, the operator does not need to disassemble the heat preservation barrel, can take out the middle furnace cylinder 3 together with the main chamber 5, then disassemble and clean the lower hot zone, and finally rotate and install the main chamber 5. If the whole hot zone needs to be cleaned, the upper lifting rod 11 and the hook part 2 can be disassembled by using the middle wrench 130. After the lifting rod body 1 is disengaged, the main chamber 5 can be rotated and opened for cleaning. After the cleaning is completed, the quick disassembly tool for the single crystal furnace can be reassembled, and the main chamber 5 can be rotated and installed.

[0045] The quick disassembly tool for the single crystal furnace can simplify the disassembly and assembly process of the single crystal furnace hot zone, reduce the dependence on professional tools and large equipment during disassembly and assembly, reduce the labor intensity of the operator, and enable ordinary technical personnel to perform hot zone disassembly and assembly operation after simple training. The quick disassembly tool for the single crystal furnace can be compatible with mainstream photovoltaic single crystal production equipment on the market, without the need for large-scale modification of the production equipment, thereby reducing the application cost.

[0046] Finally, it should be noted that the above-described embodiments are merely specific implementations of the present application, which are used to illustrate the technical solutions of the present application, rather than limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any person skilled in the art can modify or easily think of changes to the technical solutions described in the foregoing embodiments within the technical scope disclosed by the present application, or make equivalent replacements to some technical features.
