Technical Field
[0001] The utility model relates to the technical field of catalyst processing, in particular to a powder feeding system that can reduce powder wall sticking. Background Art
[0002] A catalyst generally refers to a substance that can increase the reaction rate without changing the total standard Gibbs free energy change of the reaction.

When feeding the material, the powder adheres to the inner wall of the feeding hopper, which will form the problem of powder wall sticking. The existing method is to knock on the feeding hopper with a hammer held by a person to separate the powder attached to the inner wall of the feeding hopper from the feeding hopper. This method not only has low efficiency but also consumes physical strength, so it needs to be improved. Summary of the Utility Model
