Technical Field

The utility model relates to the technical field of graphite impregnation, in particular to an anti-extravasation graphite impregnation cooling system.

Background

In order to meet the process requirements of production, it is necessary to impregnate the graphite product with an impregnating liquid at the surface, for example by introducing hot pitch into an impregnation tank, impregnating the product under high pressure and then discharging the excess pitch from the impregnation tank while it is hot.

When the impregnating solution is discharged from the impregnating tank, the pressure in the impregnating tank is reduced, and asphalt in the product is easy to extravasate. In order to avoid the extravasation of bitumen, it is necessary, on the one hand, to maintain the pressure inside the impregnation tank and, on the other hand, to carry out the cooling of the product.

The utility model patent with application number 201820842776.1 discloses an independent cooling system for impregnation, which is characterized in that inert gas is introduced into an impregnation tank, so that after the interior of the impregnation tank is kept at rated pressure, the inert gas is driven by an airflow generator to circularly flow, and the inert gas is uniformly and circularly cooled by combining a cooling mechanism, so that asphalt and a product are tightly combined, and asphalt infiltration is avoided. Since it does not disclose an internal structure, the person skilled in the art cannot know the internal gas path thereof. In fact, due to the fact that the volume of the dipping tank is large, products subjected to dipping at a time are relatively large, the introduced inert gas is easy to run straight, is discharged along with the drainage component B directly, each product cannot be taken care of, the cooling rate of the products is inconsistent, the local extravasation of asphalt is difficult to avoid, and improvement is needed.
