Technical Field

[0001] The utility model relates to the technical field of crucibles, and more specifically to a positionable crucible suitable for an internally connected graphitization furnace. Background Art

[0002] Graphite crucible is a kind of crucible made of graphite, clay, silica and wax stone. Graphite crucible uses natural flake graphite as the main raw material, and plastic refractory clay or carbon as a binder for processing. It has the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life, which is of great significance in the processing operation of enterprises.

[0003] There are two common production crucible furnaces in enterprises: Acheson crucible furnace and internal series furnace. The internal series furnace places the crucible horizontally, connects the front and back together in series, and has positive and negative electrodes on the furnace body. The series crucible group is powered on and heated. The existing crucible furnace is a cylindrical crucible, which is convenient for processing but has the problem of difficult positioning, and the crucible body is easy to roll, resulting in a decrease in the conductivity of the crucible group.

The positionable crucible has improved conductivity. Compared with the traditional cylindrical crucible with a flat surface, the new crucible has good bottom contact, is easy for current to pass through, and can save raw materials.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A positionable crucible suitable for an inner-string graphitization furnace, wherein any two adjacent crucibles among a plurality of crucibles are connected end to end, the crucible comprises a crucible body and a crucible cover, the crucible body is a cylinder with an opening at the top, the crucible cover is arranged at the opening of the crucible body, a boss is arranged at the bottom of the crucible body, and the boss is arranged in coordination with the top opening of the crucible body.

[0007] The top opening of the crucible body is arranged as a stepped hole.

[0008] The crucible cover is a circular cover, a truncated cone is concentrically arranged on the crucible cover, and the crucible cover is matched with the stepped hole.

[0009] The boss is matched with the stepped hole.

[0010] The outer hole diameter of the stepped hole is 440 mm and the depth is 50 mm, and the inner hole diameter of the stepped hole is 300 mm and the depth is 50 mm.

[0011] The diameter of the crucible cover is 440 mm and the height is 30 mm. The diameter of the truncated cone is 300 mm and the height of the truncated cone is 50 mm.

[0012] The diameter of the boss is 440 mm, and the height of the boss is 20 mm.

[0013] The outer diameter of the crucible body is 600 mm, the height of the crucible body is 1100 mm, and the thickness of the side wall and the bottom of the crucible body are both 50 mm.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The step holes reserved on the top of the crucible and the bosses on the bottom of the crucible allow for tight fit when connected in series; the contact placement makes it convenient for workers to directly perform positioning operations, saving processes, reducing working hours, and facilitating subsequent processing; the conductivity is improved, and compared with the traditional cylindrical crucible with a flat surface, the bottom of the crucible has good contact, which is easy for current to pass through and can save raw materials. The crucible cover, the bottom boss and the step holes cooperate to connect several crucibles end to end and achieve a straight linear arrangement. BRIEF DESCRIPTION OF THE DRAWINGS
