Technical Field

[0001] The utility model relates to the technical field of separation and charging of Raney nickel catalysts, in particular to a device for separating and charging Raney nickel catalysts. Background Art

[0002] Raney nickel catalyst is a commonly used metal catalyst, primarily used in the addition reaction of unsaturated compounds with hydrogen. 1,4-Butanediol (BDO), known as BDO, has advantages such as flammability, strong solubility, and low production costs. As an important fine chemical and organic chemical raw material, it is widely used in engineering plastics, synthetic fibers, pesticides, cosmetics, pharmaceuticals, and other fields.

[0003] A chemical company has nine BDO reactors. These reactors react 1,4-butynediol with hydrogen over a Raney nickel catalyst to produce 1,4-butanediol. After long-term operation, Raney nickel catalyst fines enter the reactors, disrupting the production process and reducing catalytic performance, thereby lowering 1,4-butanediol production. Each BDO reactor requires a regular replacement of 100 barrels of Raney nickel catalyst every three months.

[0004] Therefore, before introducing the Raney nickel catalyst into the BDO reactor, it is necessary to screen and remove the powder. During the screening process, the workers manually sieve the Raney nickel catalyst, which takes a long time and reduces the production efficiency of the BDO reactor. It is also labor-intensive, and the dust generated during the screening process can cause great harm to the health of the workers. Summary of the Invention
