Abstract

The invention discloses a rare earth fluorescent powder waste mixing and stirring device with crushing function, and relates to the technical field of light powder waste treatment. A purpose of the invention is mainly aims to solve the problem that fluorescent powder waste particles are large and are uniformly mixed and reacted. The rare earth fluorescent powder waste mixing and stirring device comprises a mixing and stirring box, wherein an eccentric feeding port is formed in the top end wall of the mixing and stirring box, a discharge port is formed in the side wall of the bottom of the mixing and stirring box, a rotating rod shaft coaxial with the mixing and stirring box is arranged in the mixing and stirring box, a grinding cylinder is further arranged on the inner wall of the mixing and stirring box, the inner wall of the grinding cylinder is arranged in a horn mouth shape, an annular grinding plate of a circular-truncated-cone-shaped structure is arranged in the middle of the rotating rod shaft, a plurality of material penetrating holes are distributed in the side wall of the annular grinding plate, and grinding projections are arranged on the outer side wall of the annular grinding plate and the inner wall of the grinding cylinder. The rare earth fluorescent powder waste mixing and stirring device is simple in structure, capable of sequentially crushing, mixing and uniformly mixing, high in efficiency, convenient to operate and control and high in practicability.

Description

technical field [0001] The invention relates to the technical field of fluorescent powder waste treatment, in particular to a rare earth fluorescent powder waste mixing and stirring device with a crushing function. Background technique [0002] In the current application of rare earths, when rare earths are applied to rare earth fluorescent materials, a certain amount of rare earth phosphor waste will be produced, and if the rare earth phosphor waste is dumped or thrown away at will, it will directly cause certain pollution to the environment. Also will cause the waste of energy simultaneously, also will reduce the benefit of enterprise simultaneously; Therefore, in current technology, it is more to form yttrium europium oxalate enrichment after rare earth phosphor waste material is processed to utilize, In order to improve the economic value of the enterprise and the effective use of resources, it also helps to protect the environment; [0003] When phosphor waste is forme...
