Description
Technical field
The present invention relates to deduster field, more particularly to a kind of powder dust separating device of final dusting.
Background technique
In the preparation process of the plastic particles raw materials such as polyethylene and polypropylene, it is inevitably easy to produce various powder
Dirt, and mixing in material so that the technical process of next step is by large effect, therefore indispensable is just needed to modeling
Material raw material is dusted technique, and the existing dedusting method to various materials mainly has two kinds of sides of wind-force dedusting and oscillating plate dedusting
Formula.
And the efficiency of wind-force dedusting is apparently higher than oscillating plate now, such as entitled one kind of Patent No. 201510278115
The patent of invention of blower feeding dust separator, technical solution include cyclone separator, deduster outer barrel, deduster mesh bucket
And dust blower, cyclone separator top side offer blower charging line entrance, for connect blower charging line with to
Material is sent into the cyclone separator, and the cyclone separator upper end is provided with and communicated with dust passing away, and described
Another outlet of dust passing away connects a dust cloth bag and carries out dust；Deduster outer barrel is set to the cyclone separator
The lower part of lower section, the cyclone separator is funnel-shaped, and end, which penetrates in the deduster outer barrel, realizes interlinking between the two
It connects, the lower end of the deduster outer barrel is provided with material particles outlet, material particles after processing are discharged；Deduster mesh
Bucket, nesting are set to the deduster inside the barrel, the whole barrel-like structure in a lower end uncovered, and upper end and the whirlwind
The lower part outlet of separator is connected, and the aperture that multiple diameters are less than material particles diameter is provided on bucket wall；Dust blower
Dust mouth connect another dust cloth bag, there are two dust discharge wire rubber pipe, the dust discharge wire rubber pipe is another for suction inlet connection
End penetrates in the deduster outer barrel, and is symmetrically disposed on the deduster mesh bucket outer wall, will flow through the dedusting
The dust in material in device mesh bucket sucks the dust discharge wire rubber pipe by the aperture on the deduster mesh bucket bucket wall
In, and be delivered in dust cloth bag.Material carries out dedusting twice in cyclone separator and deduster inside the barrel, can effectively go
Except the dust on plastic grain, but this structure has also disadvantage, can not be according to different objects if the air quantity of blower can not be adjusted
Material adjusts the air quantity of blower, is thus easy to cause because the negative pressure that blower generates makes material be adsorbed on deduster mesh very much greatly
It can not fall blanking on bucket inner wall, influence the conveying of material, and material is adsorbed on deduster mesh bucket inner wall can block net
Hole influences the suction of dust.
