Description
Technical field
This utility model relates to field of plastics processing, is specifically related to a kind of feeding material choosing apparatus.
Background technology
At present in being modified plastic processes, the plastics after modification, are the most all to be set by extrusion
Standby and coordinate extrusion die that plastics are prepared as nutty structure, unified in order to ensure diameter between prepared plastic grain, carry
High product quality, is 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, sent by material
Entering subsequent processing, therefore allow for procedure of processing and increase, efficiency reduces.
Much the most existing screening plant, be by vibration screen, so that plastic grain is through screen cloth, but due to just preparation
The plastics particle temperature gone out is higher, in order to lower the temperature plastic grain, in addition it is also necessary to arranges blower fan and carries out air-cooled to plastic grain,
But owing to plastic quality is relatively light, easily raises up under airflow influence, thus make plastic grain be less useful for passing through screen cloth.
Utility model content
The purpose of this utility model is to provide the one can be while feeding, moreover it is possible to screens material and lowers the temperature
Feeding material choosing apparatus, to improve production efficiency.
For reaching above-mentioned purpose, base case of the present utility model is as follows:
Feeding material choosing apparatus includes feed pipe, and the sidewall of feed pipe offers charging aperture, and it is right that feed pipe is additionally provided with
Should be in the feed hopper of charging aperture；Also including discharge nozzle, connecting tube and charging blower fan, described charging assembling is in feed pipe one end
End, described connecting tube is fixed on the other end of feed pipe, and the air outlet of charging blower fan connects with feed pipe；Described discharge nozzle
Including connecting end and discharge end, it is provided with discharge opening between described connection end and discharge end, a diameter of connection end of described discharge opening
The 1/3～1/4 of internal diameter, the end of described connection end is fixed with taper screen cloth outwardly, connects end and inserts in feed pipe, and
Forming the annular material mouth parallel with taper screen cloth between feed pipe with discharge nozzle, connecting tube is also fixed with discharge nozzle, and connecting tube
And form reject bin between discharge nozzle, the sidewall of connecting tube is provided with waste outlet.
The principle of this programme feeding material choosing apparatus is:
Starting charging blower fan, be introduced in hopper by the plastic grain of plastic granulator output, therefore plastic grain will be with
Air-flow moves along feed pipe；Owing to the sectional area of discharge opening and annular material mouth is all little than the sectional area of feed pipe, therefore feed
Air-flow in pipe will flow out from discharge opening and annular material hole simultaneously；When plastic grain flows in feed pipe, taper can be impinged upon
On screen cloth, the least granule will pass through taper screen cloth, and the plastic grain that can not pass through taper screen cloth will be at gas
Enter reject bin from annular material mouth under the effect of stream, and discharge from waste outlet；Then entered out by the granule of taper screen cloth
Material pipe, and discharged by discharge opening.
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；The 1/3～1/4 of a diameter of connection end internal diameter of discharge opening, the beneficially airflow diversion in discharge nozzle becomes two strands
Air-flow so that plastic grain can export dischargings from two, and the sidewall of annular material mouth is parallel with screen surface, then can form one
Stock skims over the air-flow of screen surface, thus the plastic grain that will not pass through screen cloth brings annular material mouth into, it is to avoid screen cloth is blocked；
Additionally arrange reject bin can so that waste material is collected, and charging blower fan can charging while material is dropped
Temperature.
Preferred version one: as the further optimization to base case, described connecting tube and discharge nozzle are fixed with mutually
The flange coordinated, and between flange, it is provided with sealing ring；Dismounting and maintenance is conducive to by Flange joint feed pipe and discharge nozzle,
The most easy to assembly.
Preferred version two: as the further optimization to base case, be provided with regulation valve at described charging aperture, regulate valve
Plastic grain can be regulated and enter the flow in feed pipe, thus be conducive to controlling plastic grain and the mixing of air in feed pipe
Ratio, it is ensured that material flow, in order to control to select materials.
Preferred version three: as the further optimization to base case, described discharge opening is transitioned into connection end by taper hole
And discharge end；Discharge opening passes through discharge opening with feed end and discharge end by taper hole transition, beneficially plastic grain, and works as plastics
Granule, by after discharge opening, contributes to again granule dispersion, to ensure the mobility of material.
Preferred version four: as the further optimization to base case, connect at described waste outlet and have threeway, threeway
One end is provided with discharging blower fan；The purpose arranging threeway is to install discharging blower fan, can further enhance after installing discharging blower fan
Material fluidity, contributes to discharging, and also can form certain negative pressure in reject bin, with by waste material sucking-off.
Preferred version five: as the further optimization to preferred version three, described threeway is also associated with connect reject bin
Circulating line with feed hopper；Due to merely through primary screening, it is impossible to thoroughly screened by material, therefore circulating line is set
After material repeatedly can be screened.
Preferred version six: as the further optimization to preferred version four, described charging blower fan and discharging blower fan be from
Sub-blower fan；Owing to plastics easily produce electrostatic during friction, and feed blower fan and discharging blower fan employing ion blower, can
Effectively to go to destatic, and then preventing plastic grain from mutually boning or adsorb on feed pipe sidewall or screen cloth, impact is selected materials.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Reference in Figure of description includes: feed pipe 1, connecting tube 2, discharge nozzle 3, charging blower fan 11, annular material
