[0002] Mixing is a crucial step in the production of powdered catalysts, as it directly affects the performance and effectiveness of the catalyst. The main purpose of the mixing process is to uniformly disperse powders of different components to ensure the uniformity among the active components, support, and additives of the catalyst.

[0003] V-type mixers are commonly used when mixing powdered catalysts. These mixers have a V-shaped mixing structure. After feeding from both ends, the material rotates and mixes inside the V-shaped cylinder. After the mixing process, a receiving bucket is placed below the discharge end of the V-shaped mixing mechanism. Since different receiving buckets have different heights and the material being mixed is powdered catalyst, if the opening of the receiving bucket is far from the discharge end, the powdered catalyst will spill, causing not only product waste but also pollution to the production environment. In view of this, this solution proposes a mixing device for catalyst production to solve the above problems. Utility Model Content
