Description

technical field [0001] The invention belongs to the technical field of chemical preparation, and in particular relates to a drying device for preparing zinc oxide. Background technique [0002] Zinc oxide is an inorganic substance with the chemical formula ZnO, which is an oxide of zinc. Insoluble in water, soluble in acid and strong alkali. Zinc oxide is a commonly used chemical additive, widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paint coatings, ointments, adhesives, food, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room temperature light-emitting performance. It is used in liquid crystal displays, thin-film transistors, and light-emitting diodes in the semiconductor field. In addition, microparticles of zinc oxide as a nanomaterial have also begun to play a role in related fields. In the prior art, when preparing zinc o...

Problems solved by technology

In addition, microparticles of zinc oxide as a nanomaterial have also begun to play a role in related fields. In the prior art, when preparing zinc oxide nanoparticles, it is usually necessary to use a drying device to dry the zinc oxide nanoparticles with hot air. However, nowadays The structure of the drying equipment is complicated, and the zinc oxide nanoparticles are piled up in the drying cylinder for drying. The zinc oxide nanoparticles are relatively static in the drying device, which is not effective for the zinc oxide nanoparticles, and the efficiency is not high, which affects the efficiency of the staff.
