Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and therefore are only examples, and the protection scope of the present invention is not limited thereby.

It is to be noted that unless otherwise specified, technical or scientific terms used herein shall have the ordinary meaning as understood by those skilled in the art to which the present invention belongs.

Example 1

As shown in fig. 1 to 3, embodiment 1 of the present invention provides a crucible for a graphitization furnace, which includes a crucible body 100 and a crucible cover 200 covering the crucible body 100.

The crucible body 100 is used for containing graphite powder, a groove is formed in the contact area of the surface of the crucible cover 200 and the crucible body 100, the groove and the surface of the crucible body 100 form an exhaust passage 300, and the exhaust passage 300 is communicated with the inside and the outside of the crucible body 100.

Specifically, the crucible cover 200 includes a cover plate portion 210 and a protrusion 220 disposed on one side of the cover plate portion 210, the cover plate portion 210 is attached to the end portion of the crucible body 100, the surface of the cover plate portion 210 facing the crucible body 100 is provided with at least one first groove 211 extending from the protrusion 220 to the outer peripheral surface of the cover plate portion 210, the protrusion 220 is embedded in the crucible body 100 and attached to the inner side wall of the crucible body 100, the outer peripheral surface of the protrusion 220 is provided with at least one second groove 221 extending from the cover plate portion 210 to the end surface of the protrusion 220, and the first groove 211 is connected to the second groove 221.

In this embodiment, the width of the second groove 221 is greater than the width of the first groove 211. The width of the first groove 211 on the cover plate part 210 is set to be smaller, external impurities are not easy to enter the crucible through the exhaust channel 300, the width of the second groove 221 on the protruding part 220 is set to be wider, and the larger the width of the groove is, the more difficult the groove is to be blocked.

In this embodiment, the crucible body 100 has a cylindrical barrel-shaped structure, and the lid plate portion 210 and the protruding portion 220 of the crucible cover 200 have a cylindrical structure coaxially disposed. Preferably, four first grooves 211 are formed on the surface of the cover plate part 210 of the crucible cover 200 facing the crucible body 100, four second grooves 221 are formed on the outer peripheral surface of the protrusion 220, and the second grooves 221 are arranged at equal intervals in the circumferential direction, which has the advantages of reasonable layout and uniform exhaust.

This application sets up the recess through the region of the surface at crucible cover 200 and crucible body 100 contact, when covering crucible cover 200, the recess constitutes exhaust passage 300 with crucible body 100's surface, in the production process, the gas that produces in the crucible can in time be discharged through exhaust passage 300, because the recess that constitutes exhaust passage 300 sets up on crucible cover 200's surface, difficult emergence blocks, even the outer recess of crucible cover 200 is blocked up, also clear up very easily, therefore the easy problem that blocks takes place of current crucible exhaust hole has been solved betterly.

Example 2

As shown in fig. 4 and 5, example 2 provides a crucible for a graphitization furnace, and example 2 is substantially the same as example 1 except for the shape of the crucible.

In this embodiment, the crucible body 100 has a rectangular parallelepiped barrel-shaped structure, and the cover plate portion 210 and the protruding portion 220 of the crucible cover 200 have a rectangular parallelepiped structure coaxially disposed. Preferably, four first grooves 211 are formed on the surface of the cover plate part 210 of the crucible cover 200 facing one side of the crucible body 100, four second grooves 221 are formed on the outer peripheral surface of the protrusion 220, and each second groove 221 is correspondingly formed on one side surface of the protrusion 220 with a rectangular parallelepiped structure.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
