Description
Technical Field
The utility model relates to a crucible, in particular to an exhaust regeneration crucible for a graphitization furnace.
Background
At present, most of the crucibles adopted by graphitization furnaces are carbonaceous crucibles, the materials fired in the crucibles are negative electrode materials of batteries, the negative electrode materials are filled in the crucibles and then covered tightly on a crucible cover, and when the crucibles are filled in the graphitization furnaces, electric and heat conducting materials are added between the crucibles, and the materials are tamped, otherwise, the electric and heat conducting effects are influenced, and finally the product quality is influenced. In the firing process, the anode material carries certain moisture, the anode material is fired at a high temperature of 2700-3000 ℃ for a long time, the moisture in the anode material is evaporated to form steam, and the crucible is easy to explode or crack due to the fact that the crucible cover is fastened and the compacted material is arranged around the crucible, so that the service life of the crucible is seriously shortened, and the crucible can be used for 2-3 times, so that waste is generated, and a great potential safety hazard exists.
Disclosure of Invention
The utility model aims to provide the exhaust regeneration crucible for the graphitization furnace, which can exhaust steam in the crucible, avoid the explosion of the crucible and prolong the service life of the crucible.
The utility model is implemented by the following technical scheme: an exhaust regeneration crucible for a graphitization furnace comprises a cover, a tank body and a plurality of exhaust grooves formed in the edge of the top of the tank body; the cover is movably arranged at the top of the tank body; the bottom of the cover and the exhaust groove form a bent exhaust channel, and two ends of the exhaust channel are respectively communicated with the inside and the outside of the tank body.
Further, the exhaust passage is zigzag.
Further, an exhaust cavity is communicated between at least two adjacent exhaust channels.
The utility model has the advantages that: according to the utility model, the exhaust channel is arranged at the top of the regeneration crucible tank body, so that steam generated by the battery cathode material in the regeneration crucible tank body during high-temperature firing can be discharged in time, the explosion of the regeneration crucible is avoided, the service life of the regeneration crucible is doubled, and meanwhile, the production potential safety hazard is reduced. The exhaust channel arranged on the regeneration crucible is Z-shaped, so that waste caused by that the battery cathode material in the regeneration crucible is discharged out of the tank body along with steam is avoided; meanwhile, an exhaust cavity is communicated between two adjacent exhaust channels, and after one exhaust channel is blocked, steam can be discharged from the other exhaust channel through the exhaust cavity. When the tank body is cleaned after the use, the exhaust groove is more convenient for cleaning the battery cathode material blocked in the exhaust groove.

In the figure: the device comprises a tank body 1, a cover 2, an exhaust channel 3, an exhaust groove 4 and an exhaust cavity 5.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Example 1
As shown in fig. 1 to 3, an exhausted regeneration crucible for a graphitization furnace comprises a tank body 1, a cover 2 and three exhaust grooves 4 formed at the top edge of the tank body 1; the exhaust groove 4 is Z-shaped, and the Z-shaped exhaust groove 4 avoids the waste of materials caused by the fact that the battery negative electrode materials in the regeneration crucible are discharged out of the tank body 1 along with steam, and is convenient for cleaning the battery negative electrode materials blocked in the regeneration crucible. The cover 2 is movably arranged at the top of the tank body 1, and the bottom of the cover 2 and the exhaust groove 4 form a bent exhaust channel 3. The two ends of the exhaust passage 3 are respectively communicated with the inside and the outside of the tank body 1.
The operation procedure of this embodiment:
and (3) filling the battery anode material to be fired into a regeneration crucible, covering the cover 2, putting into a graphitization furnace for firing, and discharging steam from the exhaust channel 3 in the firing process to realize pressure relief.
Example 2
As shown in fig. 4, an evacuable regeneration crucible for a graphitization furnace has the same overall structure as that of example 1, except that an exhaust chamber 5 is communicated between two adjacent exhaust passages 3. After one of the exhaust channels 3 is blocked, steam can be discharged from the other exhaust channel 3 through the exhaust cavity 5, so that accidents caused by the blocking of the exhaust channels 3 are avoided.
The operation procedure of this embodiment:
and (3) filling the battery anode material to be fired into a regeneration crucible, covering the cover 2, putting into a graphitization furnace for firing, and discharging steam from the exhaust channel 3 in the firing process to realize pressure relief.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
