Particle drying and screening device

The utility model relates to the technical field of particle screening, in particular to a particle drying and screening device, and solves the problems that in the prior art, in order to prevent wet particles from staining a screen of a screening frame during screening, the wet particles in each tray need to be screened after being dried for a period of time, the drying waiting time is long, and the screening efficiency is high. And therefore, the particle screening efficiency is reduced. A particle drying and screening device comprises a supporting frame, a plurality of rolling wheels are arranged at the lower end of the supporting frame, a mounting frame is fixedly connected to the supporting frame, a collecting box is arranged in the mounting frame, a plurality of air holes are formed in the collecting box, a moving frame is slidably connected to the supporting frame, and the moving frame is provided with a plurality of air holes. A screening mechanism used for achieving particle screening is arranged in
