[0002] Activated alumina, also known as activated bauxite, is usually called "activated alumina" when used in catalysts. It is a porous, highly dispersed solid material with a large surface area. Its microporous surface has the characteristics required for catalysis, such as adsorption performance, surface activity, excellent thermal stability, etc., so it is widely used as a catalyst and catalyst carrier for chemical reactions. In the process of processing activated alumina, a quantitative delivery device is required to deliver it quantitatively, but the existing quantitative delivery device has certain inconveniences when used.

[0003] The utility model patent with announcement number CN217457412U proposes an automatic quantitative conveying device for activated alumina, including a conveyor belt, a storage frame, a conical barrel and a bottom plate.
