Description

Catalyst granulation device

Technical Field

The utility model relates to the field of catalyst production, in particular to a catalyst granulation device.

Background Art

A catalyst is a substance that can change the chemical reaction rate of other substances in a chemical reaction but does not change the chemical equilibrium, and its own mass and chemical properties do not change before and after the chemical reaction. Catalysts have different shapes such as cylindrical, annular, spherical, pressed tablets, mesh, powder and strips. Therefore, when producing catalysts, a granulating device is required to produce the catalysts into different shapes.

After searching, the Chinese patent announcement number is CN217527371U, which discloses a granulation device for catalyst production. The patent sets a first receiving plate and a second receiving plate to fall downward, so that the catalyst particles form two buffers when falling, so the impact of the catalyst particles inside the receiving box is small, and a receiving vibration component is set at the bottom of the receiving box to enable the catalyst inside the receiving box to move continuously, so that the catalysts will not stick to each other and agglomerate; at the same time, the catalyst particles can also be hot-air dried by the hot air drying component, thereby further reducing the amount of catalyst particles agglomerating.

However, during granulation, some catalyst raw materials may adhere to the granulation roller. If they are not cleaned in time, the size of the groove of the granulation roller will change, thereby changing the size of the granulation and affecting the granulation effect.
