[0013] 1. The utility model connects the device to an external power supply through a line and starts it through an external controller.

At the same time, the multiple diverter plates on the top assist in separating the catalyst particles. In this way, the catalyst particles can be continuously turned over to prevent them from sticking, and the drying speed can be accelerated. BRIEF DESCRIPTION OF THE DRAWINGS
