[0002] Silicon carbide micropowder refers to micron-sized silicon carbide powder that is ultra-finely crushed and graded using JZFZ equipment. It is used for wire cutting of potassium arsenide and quartz crystals and is an engineering processing material in the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry. When actually processing silicon carbide micropowder, a drying device is required to complete the drying of the silicon carbide micropowder. In actual use, it has the advantages of simple operation, stable structure, and good use effect.

The staff first places the silicon carbide micropowder raw material in the feed hopper, and then drops it into the drying box. At this time, the motor and the heating plate can be started by operating the control panel, and the silicon carbide micropowder raw material can be dried by the heating plate; the transmission rod and the reciprocating screw are driven to rotate by the output end of the motor. The L-shaped rod is driven to move up and down by the cooperation of the connecting block and the sliding rod. The raw materials in the feed hopper are dredged by the up and down movement of the L-shaped rod in the feed hopper to avoid blockage in the feed hopper. The rotating rod and the stirring rod are driven to rotate by the rotation of the transmission rod and the reciprocating screw. The silicon carbide micropowder raw material is stirred by the rotation of the stirring rod, so that it rolls, is heated evenly, and has a good drying effect.
