[0002] Catalyst preparation refers to the production of catalysts. Usually, catalysts are produced by mixing multiple raw materials and reacting them to form catalysts. Catalyst preparation usually adopts impregnation method, precipitation method and blending method, etc. Different methods are used according to the characteristics of different raw materials.

[0003] The existing mixing device for catalyst preparation has poor mixing effect, so some people think of setting an ultrasonic transmitter inside the device to assist mixing by ultrasound to improve the mixing effect. For example, Chinese utility model patent with announcement number CN219002878U specifically discloses a mixing device for preparing catalyst.

[0004] However, in the actual use of the mixing device for preparing the catalyst, people will find that the device is to add the powder material and the liquid material separately and enter the mixing box through the conveying pipe at the same time. However, when the powder material and the liquid material are in direct contact, agglomeration is likely to occur, thereby clogging the conveying pipe, affecting normal feeding, and greatly reducing its practicality.
