Description

Technical Field

[0001] The utility model relates to the technical field of zinc oxide preparation, and more particularly to a stirring device for zinc oxide preparation. Background Art

[0002] Zinc oxide is a white solid powder that is insoluble in water but soluble in acids and strong bases. It is used as an additive in a variety of materials and products, including plastics, ceramics, glass, cement, lubricants, paints, ointments, adhesives, caulking materials, pigments, foods (zinc supplements), batteries, ferrite materials, flame retardants, and medical first aid bandages.

[0003] In addition, zinc oxide is a wide-bandgap semiconductor material with a bandgap of approximately 3.3 eV at room temperature and an exciton binding energy of up to 60 meV. Due to its wide-bandgap characteristics, zinc oxide has important applications in the field of optoelectronics, especially in ultraviolet LEDs and laser diodes (LDs), and is expected to replace GaN as the material for manufacturing ultraviolet LDs and LEDs.

[0004] In the preparation process of zinc oxide, the raw materials need to be crushed, ball-milled, washed and classified, floated, concentrated, and dried;

[0005] In the conventional drying process, zinc oxide is mainly heated by a heating structure provided in the box, and is usually stirred in conjunction with a stirring structure to ensure uniform heating and drying of the zinc oxide. However, during use, the above method requires continuous stirring to ensure contact between the zinc oxide material and the heating source on the inner wall of the box. The stirring structure is the structure that is in the closest contact with the zinc oxide, but it cannot heat the zinc oxide itself to achieve heating and drying. As a result, the heating uniformity, sufficiency and heating efficiency of the zinc oxide raw material are poor, affecting the drying efficiency of the zinc oxide.

[0006] In addition, the stirring devices in the existing zinc oxide drying devices are mostly structures such as stirring rods or plate-shaped stirring blades. When drying the zinc oxide, it is necessary to stop feeding and discharging. In particular, drying cannot be carried out during feeding and discharging, resulting in poor efficiency in drying the zinc oxide, and the inability to achieve streamlined operation, which affects the operating efficiency.
