Mechanical screening device

Abstract

The invention discloses a mechanical screening device. The mechanical screening device comprises a hemispherical seat, a balance ball is fixedly connected to the middle position of the inner surface of the hemispherical seat, a partition plate is movably connected to the position, close to the balance ball, of the inner surface of a screening barrel, a fluctuating mechanism is movably connected to the side, away from the balance ball, of the partition plate, and a spherical soft plate is movably connected to the side, away from the partition plate, of the fluctuating mechanism. An inclination angle mechanism is movably connected to the position, located on the partition plate, of the outer surface of the screening barrel, screening holes are formed in the position, located above the spherical soft plate, of the outer surface of the screening barrel, and a water injector is fixedly connected to the middle position of the top of a top cover. The invention relates to the mechanical technical field. Water flow is used for cleaning away dust on the surfaces of plastic particles, dust is prevented from influencing the weight of the particles, the particles are effectively layered through different water buoyancy degrees caused by different shapes of the particles, meanwhile, the device obliquely rotates, the particles are layered and discharged, and the particle screening quality is guaranteed.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a mechanical screening device. Background technique [0002] Material screening is to separate sand, gravel, dust and other sundries in the material through the filter sieve. The traditional screening method is to manually shake the filter sieve for screening, which has low efficiency and high labor intensity. The structure of the existing vibrating screening machine is relatively complicated, and each vibrating screen needs to be equipped with a vibrating mechanism, and the manufacturing cost is relatively high. [0003] According to Chinese patent CN106862078B, the air separation device can be used to separate the large particles and small particles first, and then further sort through the oblique screening device and the tail screening device, which combines the advantages of air selection, and the oblique screening device And the tail screening device adopts a rotary sc...

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a mechanical screening device, which solves the problem that during the use of the existing mechanical screening device, the contaminants on the particle surface will change the weight of the particle itself, which affects the actual screening. effect, resulting in the mixing of screened particles with each other, and the quality of screened plastic particles cannot be guaranteed
