Description

Technical Field

[0001] The invention relates to the technical field of zinc oxide production equipment, in particular to an oxygen injection calcining device for zinc oxide production. Background Art

[0002] Zinc oxide is produced by heating electrolytic zinc ingots to a temperature of 600-700°C to melt, then placing them in a high-temperature crucible and allowing them to melt and vaporize at 1250-1300°C. Hot air is then introduced for oxidation. The resulting zinc oxide is cooled, separated by a cyclone, and the fine particles are collected in a bag to produce the finished product. Zinc oxide is a commonly used chemical additive, 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 band gap and exciton binding energy, high transparency, and excellent room-temperature luminescence properties. It is used in semiconductor products such as liquid crystal displays, thin-film transistors, and light-emitting diodes.

[0003] As the closest existing technology, Chinese patent publication number CN214065725U discloses an oxygen injection calcining device for zinc oxide production, comprising a lower furnace, an upper furnace, a support frame and a fixed plate.
