Problems solved by technology

[0002] At present, in the production process of high-purity graphite, the impregnation process of graphite equipment materials adopts the static pressure impregnation method, that is, the graphite material is placed in a closed container, heated and dried by pumping negative pressure, and then injected with impregnated pitch until the graphite material is immersed. Introduce compressed air to pressurize the container to a certain pressure and keep the pressure for a period of time, impregnate the graphite material with asphalt in a static state, and then combine the asphalt and graphite material by heating and curing; but the traditional static pressure impregnation method It is difficult for the impregnating liquid to enter the micropores of graphite. After solidification, the internal thermal expansion of the graphite material will be inconsistent, which will easily cause stress concentration and cause harm to the performance of the overall graphite material. Chinese patent CN105800606A sets an ultrasonic generator on the impregnation barrel, using The cavitation effect of ultrasonic waves on resin liquid or other impregnating agents can make the impregnating resin or other impregnating agents continuously and evenly penetrate deep into the pores of graphite materials, and continuously push the impregnating liquid into the pores of graphite materials to achieve It changed the impregnation process from traditional macro impregnation to ultrasonic micro impregnation, improved the impregnation effect of graphite impregnation, and improved the high mechanical strength, consistency and impermeability of impregnated graphite products; but the existing graphite impregnation technology still exists The amount of impregnating liquid is too much, and the use of an ultrasonic generator increases the cost of impregnation; therefore, a graphite product electrode impregnation device is required
