Screening device with detection mechanism for fluorescent powder waste

Abstract

The invention discloses a screening device with a detection mechanism for fluorescent powder waste, comprising a detection conveying mechanism, a screening mechanism and a material guide mechanism, the screening mechanism is arranged at the upper end of the detection conveying mechanism, and the material guide mechanism is arranged at the detection conveying mechanism output end; the beneficial effect of the present invention is that the size difference of phosphor waste after screening is small, the specification uniformity is high, and it is convenient for secondary treatment in the later stage. Reasonable design, high flexibility in use, the first ball and the second ball have a better space for movement, avoiding damage to the device caused by long-term rigid extrusion, increasing maintenance costs, phosphor waste is easy to slip from the lower end of the push cover , and the pushing component can cooperate with the anti-skid piece, and the pushing component can be pushed to the middle of the super-standard phosphor waste, further improving the screening fineness of the screening device.

Description

technical field [0001] The invention relates to the technical field of fluorescent powder waste processing equipment, in particular to a screening device with a detection mechanism for fluorescent powder waste. Background technique [0002] In the 1980s, my country's rare earth industry rose rapidly relying on the advantage of having the world's largest rare earth resources. Due to the unique properties of rare earth elements in magneto-optical and other aspects, they have been widely used. Because the addition of rare earth elements in phosphors can significantly improve the light efficiency, color rendering and lifespan of fluorescent lamps, rare earth phosphors are widely used in the fields of fluorescent lamps, semiconductor lighting light-emitting diodes and color picture tubes and other luminescent materials. With the promotion of my country's green lighting projects, a large amount of phosphor waste will be produced every year. If it is not treated, it will not only p...

Problems solved by technology

With the promotion of my country's green lighting projects, a large amount of phosphor waste will be produced every year. If it is not treated, it will not only pollute the environment, but also cause a waste of rare earth resources.

[0003] Materials need to be sieved during phosphor waste treatment. However, current phosphor waste sieving devices do not have a material specification detection mechanism, which makes the sieved phosphor waste uneven in size and often contains larger specifications. During the second transportation, processing and extraction, the transportation takes up a lot of space due to uneven specifications, which will cause certain damage to the processing machinery. additional questions
