[0022] Working principle: In the prior art, in order to distinguish particles of different diameters during the screening process, multi-level screening is required, and the screening process is relatively long. In addition, during the screening process, the sieve holes on the sieve plate 7 are prone to clogging and need to be cleaned regularly, resulting in the screening process not being able to be carried out continuously and effectively, thereby greatly reducing the screening efficiency. Therefore, in view of the above problems, a flame-retardant PBT processing granular material screening device is proposed; in the process of screening PBT particles, the particles to be screened are first dropped into the tank body 5 through the feed hopper 13, and then the first motor 6 is started to make the rotating shaft drive the sieve plate 7 to rotate, and at the same time, the second motor 10 is started to make the turntable 11 rotate, and then the swing rod 12 drives the collecting trough 3 to move back and forth along the slide rail 2, so that the tank body 5 reciprocates. The sieve plate 7 is shaken, and the small particles fall into the small particle collection chamber 303 along the leakage groove 8 through the shaking of the tank body 5 and the rotation of the sieve plate 7, and the large particles fall into the large particle collection chamber 301 from the sieve holes, and the qualified particles slide along the receiving filter plate 9 into the qualified particle collection chamber 302, so that the particles of different diameters can be quickly screened and separated, and the particles of different diameters can be classified and collected at the same time. Through the rotation of the sieve plate 7, because the receiving filter plate 9 and the sieve plate 7 are staggered, the sieve holes on the sieve plate 7 can be cleaned with the cooperation of the receiving filter plate 9, so that the sieve holes on the sieve plate 7 can be prevented from being easily blocked, thereby improving the screening effect of the sieve plate 7, and at the same time, the screening process can be carried out continuously and effectively, thereby greatly improving the screening efficiency;
[0023] When using the device, in order to avoid a large number of particles entering at one time causing a large amount of screened particles to accumulate on the sieve plate 7, resulting in the particles being unable to be completely screened, it is necessary to adjust the opening size of the feed hopper 13 as needed, and by moving the fixed frame 18, drive the screw 17 to move in the arc groove 16, thereby driving the two movable plates 15 to move. When the two movable plates 15 are moved to meet the opening size requirements of the feed hopper 13, the locking cap 19 is used to fix the screw 17 and the fixed frame 18, so that the movable plate 15 can be fixed in the current position, so that the opening size of the feed hopper 13 can be adjusted as needed, to avoid a large number of particles entering at one time causing a large amount of screened particles to accumulate on the sieve plate 7, resulting in the particles being unable to be completely screened, thereby improving the subsequent screening effect of the granular materials.
