Description

Technical Field

[0001] This utility model relates to the technical field of single crystal furnaces, and in particular to a disassembly and assembly device for hot zone components of a single crystal furnace. Background Technology

[0002] In the production of monocrystalline silicon, the hot zone components of the monocrystalline furnace (such as crucible supports, crucible sides, quartz crucibles, crucible bottom materials, and heaters) need to be cleaned and inspected for each furnace, which requires disassembling and reassembling these components. Currently, the disassembly and reassembly method requires opening the main furnace chamber and disassembling the hot zone components one by one in sequence. This operation is complex and time-consuming, usually requiring at least two operators to work together. This not only increases labor costs and is inefficient, but also carries the risk of damage to the hot zone components due to human error. Utility Model Content

[0005] Furthermore, the first hook is fixedly connected to the bottom of the support leg, and the support leg is rotatably connected to the mounting base.

[0006] Furthermore, the mounting base is provided with a rotating hole, the upper end of the support leg is rotatably connected in the rotating hole, and the upper end of the support leg is provided with a first knob, which extends from bottom to top out of the rotating hole.

[0008] Furthermore, a hook is provided at the upper end of the mounting base.

[0009] Furthermore, the mounting base has a Y-shaped cross-section, and the multiple legs are located at multiple ends of the mounting base.

[0010] Furthermore, the mounting base is a stainless steel base, and the support legs are stainless steel support legs.

[0014] The beneficial effects of this utility model are:

[0015] Compared with the shortcomings of the prior art, in this utility model, the hot zone components of the single crystal furnace are disassembled and assembled using a disassembly and assembly device. Instead of disassembling the insulation tank, the crucible, crucible side, crucible support, heater, and other devices are directly hoisted to achieve disassembly and assembly, which facilitates pipe cleaning. Therefore, this utility model simplifies the disassembly and assembly steps of the hot zone components without opening the main furnace chamber, thereby reducing the risk of damage to the hot zone components during disassembly and assembly, reducing personnel operation, and improving work efficiency. Thus, this utility model has the advantages of easy disassembly and assembly, reduced personnel operation, and improved work efficiency. Attached Figure Description

[0027] When it is necessary to hoist the crucible, without opening the main furnace chamber of the single crystal furnace, the disassembly and assembly device is inserted through the gap between the heater and the crucible side. At this time, multiple support legs 2 are arranged around the outside of the crucible. The first hook 3 is further rotated so that the first hook 3 faces inward to support the bottom of the crucible support. The mounting base 1 is then lifted by the hoisting machine to lift the crucible support, crucible side, crucible and crucible bottom material out together.

[0028] When it is necessary to hoist the heater, without opening the main furnace chamber of the single crystal furnace, the disassembly and assembly device is lowered to the middle of the heater. At this time, the heater is surrounded on the outside of multiple support legs 2. The second hook 6 is then rotated so that it faces outward and extends into the gap of the heater's heating zone, and the heater is then hoisted out.

[0029] Compared with the shortcomings of the prior art, in this utility model, the hot zone components of the single crystal furnace are disassembled and assembled using a disassembly and assembly device.

Thus, this utility model has the advantages of easy disassembly and assembly, reduced personnel operation, and improved work efficiency.

A first knob 8 is provided at the upper end of the support leg 2, and the first knob 8 extends from bottom to top out of the rotating hole 7. Specifically, by rotating the first knob 8, the support leg 2 can rotate to drive the first hook 3 to rotate, thereby adjusting the orientation of the first hook 3 for disassembly and assembly operations.

[0031] In some embodiments, the support leg 2 is provided with a mounting hole 9 communicating with the through hole 5, and the second hook 6 is provided with a second knob 10, which is exposed outside the mounting hole 9. Specifically, the orientation of the second hook 6 is adjusted by the second knob 10 for disassembly and assembly operations.

[0032] In some embodiments, a hook 11 is provided at the upper end of the mounting base 1; the cross-section of the mounting base 1 is Y-shaped, and multiple support legs 2 are respectively located at multiple ends of the mounting base 1; the mounting base 1 is a stainless steel base, and the support legs 2 are stainless steel support legs; the number of support legs 2 is three.
