Spray mechanism for preparing rare earth luminescent material and preparation method thereof

Abstract

The present invention provides a rare earth luminescent material preparation spraying mechanism and a preparation method thereof, comprising a mounting frame, a rotating spraying device penetrating through the center of the mounting frame, a graded infusion system sleeved on the rotating spraying device, and A nozzle fixedly connected to the bottom of the rotary spraying device; an anti-wall flow device is also provided under the installation frame; the anti-wall flow device is located under the rotary spraying device. The nozzle on the self-rotating gear also rotates along the center of the center wheel at the same speed and rotates along the center of the self-rotating gear to meet the requirements of uniform spraying of various rare earth and oxalic acid feed liquids, and the crystallization effect is good. The spray mechanism is equipped with a graded infusion system, so that the material liquid at the spraying point can get approximately the same water pressure, so as to ensure the uniform spraying of the material liquid.

Description

technical field [0001] The invention relates to the field of preparation equipment for luminescent materials, in particular to a spray mechanism for preparing rare earth luminescent materials and a preparation method thereof. Background technique [0002] The process of rare earth luminescence is the process in which external energy is transferred to the luminescence center, the luminescence center is excited, and then radiates back to the ground state to generate fluorescence. At present, the commonly used matrix materials generally include fluoride, sulfide, oxide and so on. The phonon energy of fluoride is the lowest, but it is easy to decompose at high temperature, and its chemical temperature resistance is poor. The sulfur element of sulfide will volatilize due to current excitation in application, which will cause relatively great damage to nature. The characteristic of oxide is chemical And high physical stability, strong structure. Often used oxides are y 2 o 3、 ...
