Technical Field

[0001] The utility model relates to the technical field of catalyst carrier vacuum impregnation, in particular to a catalyst carrier vacuum impregnation device. Background Art

[0002] Catalyst carrier, also known as support, is one of the components of supported catalysts. It is the skeleton of the active components of the catalyst, supporting the active components and dispersing them. It can also increase the strength of the catalyst. However, the carrier itself generally does not have catalytic activity. The catalyst needs to be impregnated to evenly disperse the active components on the carrier to improve its catalytic activity and selectivity.

[0003] Publication No. (CN216321977U) discloses a uniform impregnation device for a toothed ball catalyst carrier, comprising a base plate and an impregnation container, wherein a support frame is arranged on the top of the base plate, and an impregnation liquid tank is arranged on the top of the support frame, a sealing plate is arranged on the top of the impregnation liquid tank, and a manual shaft is arranged on the side of the sealing plate, the end of the impregnation liquid tank is connected with a connecting pipe, and a nozzle is arranged on the side of the connecting pipe. When the catalyst carrier is impregnated in the above-mentioned comparative document, the catalyst carrier is impregnated by the impregnation liquid tank, but the impregnation liquid tank does not have the function of vacuum impregnation of the catalyst carrier, resulting in that during the impregnation mixing process, the catalyst carrier cannot be placed in a closed oxygen-free environment, the impregnation liquid volatilizes and easily causes environmental pollution, and the impregnation liquid is exposed to oxidation in the air, so that its activity is reduced, and the catalyst carrier does not have the function of stirring during impregnation, resulting in the catalyst carrier and the impregnation liquid cannot be fully fused and contacted, the impregnation speed is slow, and it is not conducive to use by staff. For this reason, we propose a catalyst carrier vacuum impregnation device. Utility Model Content

[0024] During use: When the catalyst carrier needs to be vacuum impregnated, first place the catalyst carrier inside the storage frame 17, pour the impregnation liquid into the frame 5, and start the electric push rod 12.
