DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0020] The technical solution provided by the utility model is as follows: As Figures 1 to 4 shown, in this embodiment, a combined crucible with high fire resistance includes a pot body 1. A central column 2 is arranged at the center position inside the pot body 1. The bottom of the central column 2 is fixedly connected to the bottom of the pot body 1. A plurality of splicing plates 3 are arranged between the inner wall of the pot body 1 and the outer wall of the central column 2. The plurality of splicing plates 3 are arranged in a circular array. A first sealing plate 8 is fixedly connected to one side of the splicing plate 3 close to the central column 2. A first sealing groove 14 that slidably fits with the first sealing plate 8 is formed on the outer wall of the central column 2. The height of the first sealing plate 8 is equal to the depth of the first sealing groove 14. A first fixing mechanism acting on the first sealing plate 8 is arranged on the central column 2. A second sealing plate 9 is fixedly connected to the other side of the splicing plate 3. A second sealing groove 15 that slidably fits with the second sealing plate 9 is formed on the inner wall of the pot body 1. A second fixing mechanism acting on the second sealing plate 9 is arranged on the side wall of the pot body 1.

[0021] Among them, the first fixing mechanism consists of a connecting column 5 and a locking plate 6. A threaded hole 4 is formed at the center position of the upper surface of the central column 2. The connecting column 5 that is threadedly matched with the threaded hole 4 is arranged inside the threaded hole 4. A locking plate 6 is fixedly connected to the top of the connecting column 5.

[0022] During use, when the splicing plate 3 is installed, the upper surface of the first sealing plate 8 will just be aligned with the upper surface of the central column 2. At this time, the connecting column 5 is rotated and installed into the threaded hole 4, so that the bottom of the locking plate 6 presses against the top end of the first sealing plate 8, thereby fixing the first sealing plate 8.

[0023] Among them, the diameter of the locking plate 6 is equal to the diameter of the central column 2. The height of the splicing plate 3 is greater than the height of the central column 2. The difference between the height of the splicing plate 3 and the height of the central column 2 is equal to the height of the locking plate 6.

[0024] With such a setting, the locking plate 6 after installation can be aligned with the upper surface of the pot body 1, avoiding the protrusion of the locking plate 6 from affecting the use of the pot body 1.

[0025] Among them, symmetric grooves 7 are formed on both sides of the upper surface of the locking plate 6.

[0026] With such a setting, a handle can be formed between the two grooves 7, facilitating the staff to grip the locking plate 6.

[0027] Among them, the second fixing mechanism includes a fixing bolt 11. A through hole 12 is formed on the outer wall of the pot body 1. The through hole 12 is distributed along the radial direction of the pot body 1. A mating hole 10 is formed on the side wall of the second sealing plate 9 at the extension position of the through hole 12. The fixing bolt 11 is sequentially inserted into the through hole 12 and the mating hole 10 and is connected to the mating hole 10 through threaded cooperation.

[0028] After the splicing plate 3 is installed, the mating hole 10 on the second sealing plate 9 will be aligned with the through hole 12 on the pot body 1. At this time, just rotate and insert the fixing bolt 11 into the mating hole 10 to complete the fixation of the second sealing plate 9.

[0029] Among them, a receiving groove 13 is formed on the outer wall of the pot body 1 at the opening position of the through hole 12.

[0030] The nut of the fixing bolt 11 can be received through the provided receiving groove 13, preventing the nut of the fixing bolt 11 from protruding on the outer wall of the pot body 1.

[0031] Among them, to ensure the high fire resistance of the combined crucible, the pot body, the splicing plate and the connecting components acting on the splicing plate in the combined crucible are all made of graphite material.

[0032] The present utility model provides a combined crucible with high fire resistance, and the specific working principle is as follows:

[0033] During use, the first sealing plate 8 and the second sealing plate 9 on both sides of the splicing plate 3 are respectively slid into the first sealing groove 14 on the side wall of the central column 2 and the second sealing groove 15 on the inner wall of the pot body 1, so as to form a seal at the connection positions of the splicing plate 3 with the central column 2 and the pot body 1. Then, the connecting column 5 is rotatably installed into the threaded hole 4, and the bottom of the locking plate 6 presses against the top of the first sealing plate 8 to fix the first sealing plate 8. Then, the fixing bolt 11 is rotated and inserted into the mating hole 10 to complete the fixation of the second sealing plate 9, thereby fixing the splicing plate 3 inside the pot body 1. During disassembly, just operate in the reverse direction. This structural design can freely control the installation quantity of the splicing plate 3 according to requirements when using the crucible, forming multiple storage bins inside the pot body 1. When melting various small amounts of metal materials, the available space inside the crucible can be effectively utilized, and the working efficiency can be effectively improved.

[0034] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
