Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide production and processing, in particular to a feeding device for zinc oxide production and processing. Background Art

[0002] Zinc oxide is an inorganic compound with the chemical formula ZnO. It is an oxide of zinc. It is insoluble in water and ethanol, but soluble in acid, sodium hydroxide aqueous solution, and ammonium chloride. It is a commonly used chemical additive and is widely used in the production of plastics, silicate products, synthetic rubber, lubricants, paints and coatings, ointments, adhesives, foods, batteries, flame retardants and other products. Zinc oxide has a large energy band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence properties. It is used in liquid crystal displays, thin-film transistors, light-emitting diodes and other products in the semiconductor field. In addition, microparticle zinc oxide as a nanomaterial has also begun to play a role in related fields, and in order to facilitate the unloading of zinc oxide, a unloading device for zinc oxide production and processing is needed.

[0003] Existing zinc oxide is generally stored in a storage box and discharged through a discharge port, and is received by a receiving tube. Since powdered zinc oxide is prone to agglomeration and bridging, it will lead to unsmooth discharge. Furthermore, since the material is directly received through the receiving tube, it is easy to cause dust to float around, and it is not convenient to determine the amount of material discharged. Therefore, it is necessary to propose a discharge device for zinc oxide production and processing to solve the above-mentioned problems. Utility Model Content
