Description
Technical field
The present invention relates to plastics-production field, be specifically related 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 as nutty structure, unified in order to ensure diameter between prepared plastic grain, improve product quality, be both needed to carry out sifting sort to prepared plastic grain.
Owing to equipment limits, existing production technology all uses and first material is carried out screening and separating, the most again material is sent into subsequent processing, therefore allows for procedure of processing and increase, and efficiency reduces.
The most existing screening plant, mostly it is to pass through vibration screen, so that plastic grain is through screen cloth, but the plastics particle temperature owing to just having prepared is higher, in order to plastic grain is lowered the temperature, in addition it is also necessary to arrange blower fan and plastic grain is carried out air-cooled, but owing to plastic quality is lighter, easily raise up under airflow influence, thus make plastic grain be unfavorable for passing through screen cloth.
Summary of the invention
It is an object of the invention to provide one can be while feeding, moreover it is possible to the granule materials feeding screening plant screening material and lowering the temperature, to improve production efficiency.
For reaching above-mentioned purpose, the base case of the present invention is as follows:
Granule materials feeding screening plant includes the driving motor that outer cylinder body, barrel, sieve sub-feed tube, feed pipe are connected and the feeding fan being connected with charging line one end with barrel；Described barrel is positioned at outer cylinder body inner upper end, and barrel is rotationally connected with outer cylinder body；Pressure chamber is formed between described barrel upper end and outer cylinder body, the axial-flow leaf being fixed on barrel sidewall it is provided with in Pressure chamber, Pressure chamber is arranged over air inlet, barrel lower end is the conical section in inverted cone, and the sidewall of conical section is provided with some discharge openings, between conical section and outer cylinder body, form annular material mouth；Described outer cylinder body lower end is in trumpet-shaped butt end, the insertion butt end, upper end of described sieve sub-feed tube, and forms annular discharge gate between sieve sub-feed tube and butt end；Described sieve sub-feed tube extenal fixation has a connecting tube, and connecting tube also lower end with outer cylinder body is fixed, and forms reject bin, connect and offer waste outlet on tube wall between connecting tube and sieve sub-feed tube；Sieve sub-feed tube upper end is fixed with taper screen cloth, and sieve sub-feed tube is connected to feed pipe side.
The principle of this programme granule materials feeding screening plant is:
The plastic grain of plastic granulator output is introduced in barrel, and starts driving motor, make driving driven by motor barrel rotate；While barrel rotates, axial-flow leaf follows rotation, and in making Pressure chamber, pressure increases, and granule is discharged from discharge opening.Under the effect of the pressure, air-flow drive granule is through annular material mouth, and makes particles hit online at conical screen；The least granule will pass through taper screen cloth so that plastic pellet completes to separate.Owing to feed pipe connects feeding fan, therefore negative pressure can be formed, after plastic grain impinges upon taper screen cloth in screening material pipe, be conducive to less granule to enter and select materials in pipe, simultaneously under the effect of negative pressure, less granule is inhaled into feed pipe, and delivers to subsequent processing by feed pipe；And fail to enter the bigger plastic grain selecting materials in pipe and will enter reject bin by annular discharge gate, and discharge from waste outlet.
This programme produces and provides the benefit that:
Owing to this device is when feeding, material can be screened, therefore eliminate the step of screening independent to material, improve efficiency.Axial-flow leaf not only has increase Pressure chamber pressure, promotes the effect that plastic grain is discharged, and axial-flow leaf can also make cold air enter Pressure chamber by nearly air port, and accelerates air flowing in Pressure chamber, and then makes granule fully contact with cold air, lowers the temperature granule；Barrel lower end is in inverted cone, and the sidewall of conical section is provided with some discharge openings, concentrating to general headquarters after granule can be made to discharge, and can strengthen the probability of granule and taper screen contact with this；And plastic grain will produce centrifugal force during barrel rotation, the most more conducively plastic grain is discharged, thus improves efficiency；Screen cloth is set to taper, is conducive to bigger granule to enter in reject bin.
Preferred version one: as the further optimization to base case, described connecting tube is fixed with, on the butt end of outer cylinder body, the flange cooperated；Be conducive to this device being dismantled and keeping in repair by Flange joint outer cylinder body and sieve sub-feed tube, the most easy to assembly.
Preferred version two: as the further optimization to preferred version one, described annular material mouth is the gap that spacing is equal；This optimization can make granule concentrate to middle part further, and can strengthen granule flow velocity, makes less granule be easier to by taper screen cloth.
Preferred version three: as the further optimization to preferred version two, described annular discharge gate is the gap that spacing is equal, and taper screen cloth is identical with the tapering of annular discharge gate；This optimization can form air-flow at conical screen net surface, thus the plastic grain that will not pass through taper screen cloth is brought into rapidly in reject bin, it is to avoid taper screen cloth is blocked.
Preferred version four: as the further optimization to preferred version three, described sieve sub-feed tube upper end is fixed with pedestal, drives motor to be arranged on pedestal；Drive motor to be arranged on the select materials upper end of pipe of screening and can make more compact structure.
Preferred version five: as the further optimization to preferred version four, described feeding fan is particle blower fan；Owing to plastics easily produce electrostatic during friction, and feeding fan uses ion blower, can effectively go to destatic, and then prevents plastic grain from mutually boning or adsorb on feed pipe sidewall, affect feeding.
Preferred version six: as the further optimization to preferred version five, described connecting tube is tapered；Connecting tube is arranged to conical pipe, and beneficially waste material is discharged.
