Embodiment 1

[0016] The plastic powder sifter is basically attached figure 1 Shown:

[0017] It includes a storage tank 1, a powder stimulating mechanism, a conduit 2 and a dust removal bag 3. The powder stimulating mechanism includes a bottom plate 4, a latex sheet 6, a sliding ring 11, a reciprocating mechanism, and a powder outlet barrel 9. The bottom plate 4 is set horizontally, and the bottom plate 4 is slidably connected. On the inner wall of the material tank 1 and between the edge of the bottom plate 4 and the inner wall of the material tank 1, a seal is maintained, an upwardly arched cavity 5 is formed on the bottom surface of the bottom plate 4, and the powder outlet tube 9 is vertically fixed on the bottom plate 4, Powder outlet cylinder 9 bottoms are communicated with cavity 5, and the peripheral edge of latex sheet 6 is fixed on the peripheral edge of base plate 4, and latex sheet 6 is provided with only for gas to enter the space between latex sheet 6 and base plate 4. The f...

Embodiment 2

[0020] The difference from Embodiment 1 is that the reciprocating mechanism is an automatic reciprocating cylinder, the fixed end of the automatic reciprocating cylinder is fixed on the outer wall of the powder outlet tube 9, and the telescopic end of the automatic reciprocating cylinder is connected with the sliding ring 11.

Abstract

The invention relates to the field of dry separation methods of bulk materials, and discloses a plastic powder screening device. The device comprises a containing bucket, a powder exciting mechanism,a guide pipe and a dust removal bag; the powder exciting mechanism comprises a bottom plate, a flexible film, a sliding ring, a reciprocating motion mechanism and a powder discharging cylinder; the bottom plate is in sliding connection to the inner wall of the containing bucket, a cavity is formed in the bottom face of the bottom plate, the powder discharging cylinder is vertically fixed to the bottom plate, the peripheral edge of the flexible film is fixed to the peripheral edge of the bottom plate, a first one-way valve is arranged on the flexible film, a second one-way valve is arranged onthe bottom plate, a through hole is formed in the middle of the flexible film, the outer wall of the sliding ring is fixed to the through hole of the flexible film, the sliding ring is in sliding connection to the powder discharging cylinder, the reciprocating motion mechanism is arranged on the powder discharging cylinder, and comprises a free end, the free end is connected to the sliding ring, one end of the guide pipe is communicated to the powder discharging cylinder, and the other end o the guide pipe is communicated to the dust removal bag. According to the screening device, powder can be incessantly screened and subject to impurity removal, and manual intervention of impurity removal is avoided.

Description

technical field [0001] The invention relates to the field of dry separation of bulk materials (B07B). Background technique [0002] In the production of plastic powder, in order to ensure the quality of plastic powder, it is often necessary to sieve the processed powder to separate out larger and heavier impurities. For the screening of impurities, filtration equipment is usually used for filtration. Filtration is just adding a filter screen during the transmission process, which can easily lead to clogging of the feed end of the filter screen, and the clogged filter screen not only shortens the service life, but also requires manual intervention to remove impurities, which affects production efficiency. Contents of the invention [0003] The present invention intends to provide a plastic powder sifter, which can continuously sieve powder and remove impurities, and avoid manual intervention in the sieving process. [0004] The plastic powder sifter in this scheme include...
