Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of graphite production, in particular to a cold isostatic pressing graphite intelligent feeding and discharging device. BACKGROUND

[0002] Isostatic pressing graphite is a new type of graphite material developed in the 1960s, which has a series of excellent properties. The production of isostatic pressing graphite needs to go through the processes of crushing, screening and grinding of raw materials, melting of adhesive, and processing of batching, kneading, molding, baking, impregnation and graphitization;

[0003] Among them, the baking of the adhesive pitch is a complex chemical and physical change process. From room temperature to about 200 DEG C, the adhesive softens in a molten state, the stress in the green body relaxes, the volume slightly expands, part of the molten adhesive pitch migrates and diffuses and flows, prompting the rearrangement of particles. When the temperature is 200 to 300 DEG C, with the increase of temperature, the green body carries out dehydrogenation condensation reaction, removes moisture and carbon dioxide. When the temperature is 300 to 750 DEG C, the adhesive pitch undergoes intense decomposition, polymerization, cyclization and aromatization reactions to form semi-coke, and the amount of volatile matter is reduced. The volume of the green body shrinks again. With the increase of temperature, the semi-coke generated by the adhesive pitch changes into binding coke. When the temperature is 750 to 1100 DEG C, the atomic groups in the binding coke break, and the planar molecules rearrange, making the binding coke further shrink and densify.

[0004] Therefore, during the baking process, due to the discharge of gas and the shrinkage of volume, fine pores are left in the green body. The existence of a large number of pores will inevitably have a negative impact on the physical and mechanical properties of the body. In order to further improve the volume density, mechanical strength, thermal conductivity and other properties of the green body, isostatic pressing graphite needs to be treated by one or more times of pitch impregnation and baking. During the feeding and discharging process of the graphite product from the impregnation container, the adhesive is easy to adhere to the inner wall of the impregnation container when the adhesive surface is in a molten state, which will affect the graphite product and the next impregnation.

[0005] Therefore, we propose a cold isostatic pressing graphite intelligent feeding and discharging device. SUMMARY

[0013] The utility model further provides a use method of the intelligent feeding and discharging device for cold isostatic pressing graphite.

[0014] S1, the calcined graphite product is placed in the inside of the impregnation mold, at this time, the plugging support tray below the impregnation mold blocks the opening below the impregnation mold, so that the graphite product is located above the plugging support tray, at this time, the pitch is poured to the outer side of the graphite product, so that the graphite product is impregnated.

[0015] Step S2, when the graphite product impregnation work is finished, the push driving part drives the sealing support tray to move vertically upward inside the impregnation mold, so that the sealing support tray drives the graphite product above the impregnation end to move out of the inside of the impregnation mold, because the size of the sealing support tray is matched with the impregnation mold, so that when the sealing support tray moves vertically, the adhesive attached to the graphite product on the inner wall of the impregnation mold is scraped off by the sealing support tray;

[0016] Step S3, when the sealing support tray and the graphite product move out of the inside of the impregnation mold, the height limiting driving part drives the rod-shaped baking end feeding part and the annular baking end clamping part to move, so that the sealing support tray moves to the inside of the baking furnace for baking work again, when the baking work is finished, the rod-shaped baking end feeding part drives the sealing support tray to move to the original position again, so that the sealing support tray can return to the lower side of the impregnation mold through the push driving part, thereby facilitating the next impregnation work.
