Description
Technical field
This utility model is related to plastics-production field and in particular to a kind of granule materials feeding screening plant.
Background technology
At present in being modified plastic processes, plastics after modification, often by extrusion equipment
And coordinate extrusion die that plastics are prepared into nutty structure, in order to ensure prepared plastic grain between diameter unification, improve
Product quality, is both needed to carry out sifting sort to prepared plastic grain.
Due to equipment limit, material all using first material being carried out screening and separating, is then sent by existing production technology again
Enter subsequent processing, therefore allow for procedure of processing and increase, efficiency reduces.
In addition mostly existing screening plant, be by vibration screen, so that plastic grain passes through screen cloth, but is prepared due to firm
The plastics particle temperature going out is higher, in order to plastic grain is lowered the temperature in addition it is also necessary to arranged blower fan plastic grain is carried out air-cooled,
But because plastic quality is lighter, easily raise up under airflow influence, thus so that plastic grain is unfavorable for by screen cloth.
Utility model content
The purpose of this utility model be to provide a kind of can be moreover it is possible to being screened to material and being lowered the temperature while feeding
Granule materials feeding screening plant, with improve production efficiency.
For reaching above-mentioned purpose, base case of the present utility model is as follows：

The principle of this programme granule materials feeding screening plant is：
The plastic grain of plastic granulator output is introduced in barrel, and starts motor, make motor drive material
Cylinder rotates；While barrel rotates, axial-flow leaf follows rotation, so that pressure in Pressure chamber is increased, and granule is discharged from discharge opening.
Under the effect of the pressure, air-flow drives granule through annular material mouth, and makes particles hit online in conical screen；Then less granule
Will be by taper screen cloth so that plastic pellet completes to separate.Because feed pipe connects feeding fan, therefore in screening expects pipe
Negative pressure can be formed, after plastic grain impinges upon taper screen cloth, be conducive to less granule to enter in sorting pipe, simultaneously in negative pressure
In the presence of, less granule is inhaled into feed pipe, and delivers to subsequent processing by feed pipe；And fail to enter in sorting pipe
Larger plastic grain will enter reject bin by annular discharge gate, and discharge from waste outlet.
This programme produce beneficial effect be：
Because this device is in feeding, you can material is screened, therefore eliminate the step to the independent screening of material,
Improve efficiency.Axial-flow leaf not only has increase Pressure chamber pressure, promotes the effect that plastic grain is discharged, axial-flow leaf can also
Make cold air enter Pressure chamber by nearly air port, and accelerate air flow in Pressure chamber, and then so that granule is fully connect with cold air
Touch, granule is lowered the temperature；Barrel lower end is in inverted cone, and the side wall of conical section is provided with some discharge openings, and granule can be made to arrange
Concentrating to general headquarters after going out, can strengthen the probability of granule and taper screen contact with this；And plastic grain will produce during barrel rotation
Raw centrifugal force, more conducively plastic grain is discharged under the influence of centrifugal force, thus improving efficiency；Screen cloth is set to taper, favorably
Enter in reject bin in larger granule.
Preferred version one：As the optimization further to base case, described connecting tube is solid with the butt end of outer cylinder body
Surely there is the flange cooperating；Outer cylinder body is connected by flange and screening expects pipe is conducive to this device being dismantled and keeping in repair,
Simultaneously easy to assembly.
Preferred version two：As the optimization further to preferred version one, described annular material mouth is the equal gap of spacing；
This optimization can make granule concentrate to middle part further, and can strengthen granule flow velocity, so that less granule is easier to by conical screen
Net.
Preferred version three：As the optimization further to preferred version two, described annular discharge gate be spacing equal between
Gap, and taper screen cloth is identical with the taper of annular discharge gate；This optimization can form air-flow in taper screen surface, thus can not
Brought into rapidly in reject bin by the plastic grain of taper screen cloth, it is to avoid taper screen cloth is blocked.
Preferred version four：As the optimization further to preferred version three, described screening expects pipe upper end is fixed with pedestal, drives
Galvanic electricity machine is arranged on pedestal；The upper end that motor is arranged on screening sorting pipe can make more compact structure.
Preferred version five：As the optimization further to preferred version four, described feeding fan is particle blower fan；Due to moulding
Material easily produces electrostatic during friction, and feeding fan adopts ion blower, can effectively go to destatic, and then prevents
Plastic grain mutually bonds or adsorbs on feeding tube side wall, affects feeding.
Preferred version six：As the optimization further to preferred version five, described connecting tube is tapered；Connecting tube is arranged to
Conical pipe, is conducive to waste material to discharge.
