Description

Technical Field

[0001] This utility model relates to a lifting and loading mechanism for the hot zone of a silicon carbide induction furnace, belonging to the technical field of silicon carbide induction furnaces. Background Technology

[0002] The hot zone is an important structure of silicon carbide induction furnace. In the existing technology, the loading and unloading of the hot zone generally relies on manual handling or the use of a trolley, which has problems such as being time-consuming and labor-intensive, and the installation and positioning accuracy cannot be guaranteed, thus affecting production efficiency and production quality. Utility Model Content

[0003] This utility model proposes a lifting and loading mechanism for the hot zone of a silicon carbide induction furnace, which aims to overcome the above-mentioned shortcomings of the existing technology and realize rapid and convenient loading and unloading of the hot zone.

[0004] The technical solution of this utility model is a lifting and loading mechanism for the hot zone of a silicon carbide induction furnace. Its structure includes a hot zone tray, a lifting module, and a rotating arm assembly. The lifting module is installed below the furnace body, with its lifting end connected to the lower furnace cover. The hot zone tray is supported on the top of the lower furnace cover, and the hot zone body is supported on the hot zone tray. One end of the rotating arm assembly is mounted on a frame near the bottom of the lifting module, and the other end is connected to a support ring. A gap is provided between the hot zone tray and the lower furnace cover for the support ring to engage. During material loading, the lifting module lowers the hot zone tray. After reaching a designated height, the rotating arm assembly is screwed into place, and the lifting module continues to descend. The support ring supports the hot zone tray, allowing it to detach from the lower furnace cover and unscrew to remove the hot zone body. The loading process is the reverse.

[0005] Preferably, the hot zone tray has a protruding socket at the bottom center, and the lower furnace cover has a plug at the top center that matches the shape of the socket. When the plug and socket are inserted, there is a gap between the hot zone tray and the lower furnace cover. This allows the support ring to be easily inserted.

[0006] Preferably, the swing arm assembly includes a swing arm, one end of which is connected to a support ring, and the other end of which is connected to a shaft pin and installed in a fixed block. The shaft pin is vertically arranged and rotatably connected to bearings with seats at both ends. The two bearings with seats are located at the top and bottom of the fixed block. A thrust bearing is installed on the shaft pin at the bottom of the swing arm end, and a pressure block is installed on the shaft pin at the top of the swing arm end. A nylon washer is provided between the pressure block and the swing arm.

[0007] The advantages of this utility model are: reasonable structural design, which enables quick and convenient installation and removal of the heating field, and can effectively support the heating field during installation and removal, thereby effectively improving production efficiency and ensuring production stability.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0012] like Figure 1 , 2 As shown, a hot zone lifting and loading mechanism for a silicon carbide induction furnace includes a hot zone tray 13, a lifting module 15, and a rotating arm assembly. The lifting module 15 is installed below the furnace body, and the lifting end of the lifting module 15 is connected to the lower furnace cover 12. The hot zone tray 13 is supported on the top of the lower furnace cover 12, and the hot zone body 14 is supported on the hot zone tray 13. One end of the rotating arm assembly is installed on the side of the frame near the bottom end of the lifting module 15, and the other end of the rotating arm assembly is connected to a support ring 8. A gap is provided between the hot zone tray 13 and the lower furnace cover 12 for the support ring 8 to be inserted.

[0013] The hot zone tray 13 has a protruding socket at the bottom center, and the lower furnace cover 12 has a plug at the top center that matches the shape of the socket. When the plug and socket are inserted, there is a gap between the hot zone tray 13 and the lower furnace cover 12. This allows the support ring 8 to be easily inserted.

[0014] The rotating arm assembly includes a rotating arm 7. One end of the rotating arm 7 is connected to a support ring 8, and the other end of the rotating arm 7 is connected to a shaft pin 3 and installed in a fixed block 2. The shaft pin 3 is vertically arranged and rotatably connected to seated bearings 1 at both ends. The two seated bearings 1 are located at the top and bottom of the fixed block 2. A thrust bearing 6 is installed on the shaft pin 3 at the bottom end of the rotating arm 7, and a pressure block 4 is installed on the shaft pin 3 at the top end of the rotating arm 7. A nylon washer 5 is provided between the pressure block 4 and the rotating arm 7. The rotating arm 7 of the rotating arm assembly can rotate around the shaft pin 3, causing the support ring 8 to move out of or into the gap between the hot zone tray 13 and the lower furnace cover 12.

[0015] According to the above structure, during the material handling process, the lifting module 15 drives the hot zone tray 13 to descend. After descending to the designated height, it is screwed into the rotating arm assembly. After being screwed into place, the lifting module 15 continues to descend, and the support ring 8 supports the hot zone tray 13, causing the hot zone tray 13 to detach from the lower furnace cover 12 and be screwed out. The hot zone body 14 is then removed. The loading process is the reverse.

[0016] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0017] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
