A kind of particle screening equipment

Abstract

The invention discloses particle screening equipment. The particle screening equipment comprises a winnowing device, an oblique screening device and a horizontal screening device. The oblique screening device and the horizontal screening device are located at the two sides of the winnowing device. The particle screening equipment has the beneficial effects that by the adoption of the winnowing device, dust and super-small disqualified particles can be blown into a wind bag, most of large particles can enter the horizontal screening device to be screened through a discharging hopper A, and the particles located between the dust and super-small disqualified particles and the large particles can enter the oblique screening device to be screened through a discharging hopper B; the particle screening equipment integrates the advantages of winnowing, and meanwhile a rotating-type screening mode is adopted in the oblique screening device and the horizontal screening device, so that noise is reduced obviously compared with an existing vibration screening mode with a vibrating screen, and practicability is high; and the particle screening equipment is particularly suitable for screening plastic particles (particularly thermoplastic plastic particles), and thus the large particles, super-small disqualified particles and dust can be separated out.

Description

technical field [0001] The invention relates to a mechanical device, especially a particle screening device. Background technique [0002] The vibrating screen is a commonly used screening machine. It uses the principle of vibrating particles to sieve the particles out of the screen. The small particles fall on the screen, and the large particles are located above the screen and discharged from the other opening. The biggest problem of the vibrating screen is The noise is so loud that several vibrating screens are placed in the same workshop, and even speech cannot be heard. [0003] 201610502208.2 discloses a plastic granule screening device, which proposes to rely on the principle of air selection to sieve plastic granules, but put all plastic granules in suspension for secondary screening, which is inefficient, difficult, and not very practical. Because of such problems, it is necessary to improve the existing screening machinery. Contents of the invention [0004] Th...
