Abstract

The invention relates to the field of experimental equipment, in particular to a laboratory catalytic hydrogenation device which comprises a shell, a rotating groove is formed in the top of the shell, a rotating rod is slidably connected into the rotating groove, the bottom of the rotating rod is inserted into a base in the shell, a guide column is arranged on the upper portion of the rotating rod, and a guide groove is formed in the periphery of the guide column; a gear box is arranged on the left side of the guide column, a driving bevel gear is arranged in the gear box, and a hand wheel is connected to the top of the driving bevel gear and arranged on the top outside the shell; the right side of the driven bevel gear is connected with a threaded rod, the threaded rod is in threaded connection with a transmission block, the right side of the transmission block penetrates out of the gearbox, and the right end of the transmission block is connected with a guide piece. And a plurality of filling assemblies are arranged on the rotating rod. Therefore, the catalyst and reactants can be uniformly mixed, the hydrogenation reaction effect is improved, after the reaction is completed, the catalyst is quickly replaced, and the time is saved.

Description

technical field [0001] The invention relates to the field of experimental equipment, in particular to a laboratory catalytic hydrogenation device. Background technique [0002] The hydrogenation reaction device is a very important piece of equipment in the organic chemistry laboratory and the actual production process. The catalytic hydrogenation device for the laboratory can not only be used for gas and liquid hydrogenation reactions, gas and gas hydrogenation reactions (for example, Publication No. For: CN108579621A patent introduces a carbon dioxide hydrogenation fixed-bed reactor in detail), which can also be used in occasions where liquid and gas need to be fully mixed. [0003] At present, the existing laboratory catalytic hydrogenation device needs to directly load the catalyst into the shell of the catalytic hydrogenation reaction device, which not only has a large loading capacity, but also makes it difficult to ensure uniform contact between the catalyst and the re...
