[0002] Zinc oxide is an oxide of zinc, which is insoluble in water but soluble in acid and strong alkali. It is a white solid, so it is also called zinc white. It can be obtained by burning zinc or roasting sphalerite (zinc sulfide). In nature, zinc oxide is the main component of the mineral zincite. Although there are two ways to make artificial zinc oxide: by oxidizing pure zinc or roasting zinc ore. Zinc oxide is used as an additive in a variety of materials and products, including plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, filling materials, pigments, foods (zinc supplements), batteries, ferrite materials, flame retardant materials and medical first aid bandages.

[0003] Reference patent CN214065725U mentions an oxygen injection calcination equipment for zinc oxide production, which solves the problem of existing oxygen injection calcination equipment for zinc oxide production. When the upper furnace is used for calcination, a pressure difference will occur in the furnace body, making it inconvenient to open the sealing cover and the upper furnace, resulting in a decrease in the practicality of the overall structure.
