Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fluorescent powder processing, and in particular relates to a fluorescent powder washing device. Background Art
[0002] The principle of phosphor washing is mainly to utilize the physical and chemical properties of phosphor, as well as the solubility and permeability of water. Water can penetrate into the surface and interior of phosphor, dissolve and remove some impurities and pollutants attached to the surface of phosphor.
[0003] When water dissolves impurities attached to the phosphor, the phosphor particles tend to agglomerate, making it difficult for water to evenly contact each particle. When the phosphor is directly washed and stirred by stirring, the agglomerated phosphor can be stirred and dispersed, increasing its contact area with water, so that the particles attached to the surface of the phosphor can be washed away; but the washing and stirring process may cause partial dissolution or dispersion of the phosphor, thereby affecting its luminescent performance. The mechanical action during the washing and stirring process may also cause certain damage to the crystal structure or surface state of the phosphor, thereby affecting its luminescent effect. When the phosphor is washed without stirring, the washing effect of water simply through the flow of water is poor, which is not conducive to the washing of the phosphor. Utility Model Content
