Screening device with detection mechanism for fluorescent powder waste

Abstract

The invention discloses a screening device with a detection mechanism for fluorescent powder waste. The device comprises a detection conveying mechanism, a screening mechanism and a material guiding mechanism, wherein the screening mechanism is arranged at the upper end of the detection conveying mechanism, and the material guiding mechanism is arranged at the output end of the detection conveying mechanism. The device has the beneficial effects that the size difference of screened fluorescent powder waste is small, the specification uniformity is high, later secondary treatment is facilitated, the screening assembly can push screening and open a splash-proof plate, the structural design is reasonable, the use flexibility is high, a first ball and a second ball have a better activity space during moving, so that a condition that the device is damaged due to long-time rigid extrusion, the maintenance cost is increased, and the fluorescent powder waste is prone to slipping off from the lower end of the pushing cover is avoided, the pushing assembly can be matched with the anti-skid piece and can be pushed to the middle of the over-specification fluorescent powder waste, and the screening fineness of the screening device is further improved.

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
