Lower end is fixed with helical blade, and the width of helical blade is the 1/4～1/3 of Drying internal diameter, if the lower end of Drying is additionally provided with
Dry louvre；The driving motor driving Drying to rotate is installed on support frame as described above.
The work process of the plastic pellet drying unit of this programme is:
Close discharge valve, plastic pellet to be dried is loaded in Drying from charging aperture, be then turned on heating wire and drive
Galvanic electricity machine, then heating wire will generate heat, and drive motor that Drying will be driven to rotate, and during Drying rotation, impeller also will rotate, impeller
Air will be sucked from air inlet during rotation, and air will be pressed in plenum chamber, when air will be added by heating wire through air inlet
The full hot-air of collection in heat, i.e. plenum chamber；Connect internal for Drying with plenum chamber, therefore owing to Drying lower end is provided with louvre
Hot-air in plenum chamber will enter in Drying from louvre, to dry plastic pellet；When Drying rotates,
Helical-blade sector-meeting within Drying by the plastic pellet at edge upwardly, then moves down from middle part, therefore Drying
The position of interior plastic pellet is constantly circulated so that plastic pellet can be fully contacted with hot-air；When hot-air is through plastics
After particle, steam together will be discharged from charging aperture with moisture.In order to plastic pellet will not spill from louvre, louvre straight
Footpath arranges 3～5mm.
This programme produces and provides the benefit that:
Owing to the hot-air louvre from Drying lower end enters in Drying, therefore the heat in Drying from edge to
Center is gradually weakened, and the most gradually weakens, and Drying can be rotated by driving driven by motor, and is provided with in Drying
Helical blade, therefore under the effect of helical blade, plastic pellet can move from lower to upper part, and plastic central particle can
To move to edge, with this, plastic pellet can be heated uniformly, and reach the purpose uniformly dried；Additionally, due to setting
Impeller, therefore blast in plenum chamber will increase so that hot-air enters the speed in Drying to be increased, and due to Drying
Surface area relatively big, the flow hence into the hot-air in Drying also increases, and improves the drying effect of plastic pellet with this
Rate.
Preferred version one, as the further optimization to base case, the bottom of described Drying is taper；Drying
Bottom is set to taper and is conducive to plastic pellet to discharge, it is to avoid plastic pellet residual volume in Drying is too much.
Preferred version two, as the further optimization to base case, described Drying is by lower end barrel and upper end toper
Section is welded, and described impeller is arranged on upper end conical section；In preferred version two, the epimere of Drying is also taper, therefore
The blade of impeller can increase so that the blast in plenum chamber increases further, i.e. the speed of the hot-air in entrance Drying
Improving further, the Drying Rates of plastic pellet improves the most further.
Preferred version three, as the further optimization to preferred version two, described discharging opening is provided above and discharging opening
The feed hopper of connection；After being set to taper due to the epimere of Drying, the size of charging aperture will reduce, after therefore arranging feed hopper
Convenient charging.
Preferred version four, as the further optimization to base case, the upper end of described Drying is welded with driven gear,
Being additionally provided with reductor on support frame as described above, described driving motor via reducer connects driving gear, described driven gear
Engage with driving gear；Driving motor to use gear-driven mode to drive Drying, the rotating speed that can make Drying is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
