Stirring and mixing device for preparing fluorescent powder of LED(Light Emitting Diode)lamp

Abstract

The invention discloses a stirring and mixing device for preparing fluorescent powder of an LED(Light Emitting Diode)lamp. The device comprises a processing shell, wherein a gearbox body is arranged on the outer side wall of the top end of the processing shell and connected to a stirring rotating shaft through a meshing gear; a water conveying conduit is communicated above the stirring rotating shaft through a connecting rotating head; stirring rotating blades are arranged on side walls of both sides of the shaft body of the stirring rotating shaft and staggered from water spraying through holes; an exhaust gas conduit is communicated to the top cylinder wall of the processing shell; an air inlet hole of an exhaust gas treating chamber is connected at one end of the exhaust gas conduit; and a first active carbon adsorption layer, a second active carbon adsorption layer and a filter screen are sequentially arranged on the inner side wall of the exhaust gas treating chamber from top to bottom. The device disclosed by the invention has the advantages that the device has the function of automatic water supply to ensure that various materials can be uniformly mixed and stirred; and meanwhile, the generated toxic gas can be treated to guarantee the health of surrounding workers.

Description

technical field [0001] The invention relates to a stirring and mixing device for preparing LED lamp fluorescent powder, which belongs to the technical field of chemical mixing and stirring. Background technique [0002] Compared with traditional lighting sources, LED has many advantages such as energy saving, environmental protection, long life, small size and easy packaging. The fourth generation light source. At present, the mainstream way to obtain LEDs for lighting and decoration is the phosphor conversion method. Therefore, the preparation of fluorescent powder is the basis for the production of LED lamps. During the preparation of fluorescent powder, it is necessary to mix various raw materials for chemical reactions. In order to mix uniformly and fully for chemical reactions, it is necessary to use stirring equipment to mix various raw materials. However, the existing equipment does not mix well enough and evenly, and cannot perform the self-supplied water flushing ...

AI Technical Summary

Problems solved by technology

However, the existing equipment does not mix well enough and evenly, and cannot perform the self-supplied water flushing function. Manual operation is very troublesome, and the cleaning is often not clean. A variety of raw materials usually release a large amount of toxic and harmful gases during the mixing process. It will directly pollute the surrounding environment, and in serious cases will directly affect the life and health of workers, so the above problems need to be solved
