Further, described discharge nozzle is provided with discharge valve, for controlling the discharge rate of the molding compound after blending.
Further, described feed pipe is provided with material inlet valve, for controlling the amount of the molding compound entering dilution zone.
Further, described uniform flow bore dia is 2 ~ 4mm, and the uniform flow hole gross area is 4 ~ 8% of carrier gas distributor internal surface area.
Further, described uniform flow hole is arranged on the differing heights of carrier gas distributor by group, and this group uniform flow hole on sustained height is in this highly corresponding circumferentially evenly offering.
Further, the bottom of described cylindrical shell tilts to direction, discharge nozzle place.
Further, described heater is electrothermal tube or dividing wall type heat exchanger.
Compared with prior art, the present invention has following beneficial effect:
1, the present invention adopts wind-force as the blending power of molding compound, and molding compound is fully mixed in blending cylinder.
2, the raw material owing to entering plastic molding machine after blending mixes, and makes the ratio of the raw material of product each several part, flexibilizer identical, improves product quality.
3, the present invention adopts the design of its top feed, is not easy blocking.
4, do not have other equipment in blending cylinder, not fragile, maintenance cost is low.
5, the present invention can realize while blending, carries out preheating to molding compound, can improve plastic molding machine production efficiency.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in further detail.
Pre-heated Mold for Plastics binder blending cylinder, as shown in Figure 1 and Figure 2, the cylindrical shell 1 comprising feed hopper 2 and vertically arrange; The top of described cylindrical shell is provided with the carrier gas distributor 3 of round platform tubular, and cylindrical shell 1 interior separation is become the carrier gas pre-distributor 4 on top and the dilution zone 5 of bottom by this carrier gas distributor 3; Described carrier gas pre-distributor wall 3 is provided with the carrier gas inlet 6 of tangential admission; The round platform bus of described carrier gas distributor 3 and the angle of axis are 25 ° ~ 45 °, and this carrier gas distribution wall 3 is evenly laid with some uniform flow holes, and each uniform flow hole is tangent with carrier gas distributor outer wall and tangentially and carrier gas inlet 6 tangentially identical; Described feed hopper 2 is arranged on the side of cylindrical shell 1, is communicated with dilution zone 5 by feed pipe 7; Described bottom, dilution zone 5 is provided with discharge nozzle 8, for discharging the molding compound after blending; The outer wall of described cylindrical shell 1 being provided with heater, heating for giving the molding compound in dilution zone 5 and carrier gas.
Conveniently regulating inlet amount and load, described discharge nozzle 8 being provided with discharge valve, for controlling the discharge rate of the molding compound after blending; Described feed pipe 7 is provided with material inlet valve, for controlling the amount of the molding compound entering dilution zone.
Uniform flow hole size and percent opening directly affect the mechanical strength of distributor and carrier gas by the speed of aperture and resistance.If hole is many or diameter is excessive, the mechanical strength of distributor can be made to reduce, and the flowing velocity of carrier gas passing hole is little, the kinetic energy deficiency of Stirring then can not reach expected effect, otherwise, if hole is too small or very few, carrier gas is large by the resistance of distributor, and the energy of consumption is just large.Suitable bore dia and percent opening both can ensure the flow velocity of carrier gas by aperture, had enough kinetic energy, and gas-solid in reactor body can be made again to form the dispersion fluidisation shape of disperse.Given this, finally determine that described uniform flow bore dia is 2 ~ 4mm, and the uniform flow hole gross area is 4 ~ 8% of carrier gas distributor 3 internal surface area, preferably 5%.
Described uniform flow hole is arranged on the differing heights of carrier gas distributor 3 by group, and this group uniform flow hole on sustained height is in this highly corresponding circumferentially evenly offering.
In order to discharge is convenient, the bottom of described cylindrical shell 1 tilts to direction, discharge nozzle 8 place.
As one preferred embodiment, described heater is electrothermal tube or dividing wall type heat exchanger.
Operation principle of the present invention: carrier gas imports from the carrier gas inlet 6 of cylindrical shell 1, tangentially enter in carrier gas pre-distributor 4, carry out rotating pre-distribution, then the rotation tangential small-hole arranged on truncated cone-shaped carrier gas distributor 3 enters dilution zone, forms the rotating flow with Strong shear effect.Carrier gas rotates and moves downward and mix with the mold pressing raw material entered through feed pipe 7, mixes under strong rotation blending effect, while blending, absorbs heat energy, reaches the object of raw material preheating.Cylindrical shell is left finally by discharge nozzle 8.
On the one hand, the mutual blending between carrier gas and molding compound, collision, due to the strong shear action of strong eddy flow, easily mix; Air-flow is descending at barrel surface rotating screw on the other hand, and not sticky wall does not deposit, and does not have other equipment in cylindrical shell, not fragile.
In actual use, carrier gas can use the gas that compressed air, nitrogen, carbon dioxide etc. and molding compound do not react.
The above embodiment of the present invention is only for example of the present invention is described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, other multi-form change and variations can also be made on the basis of the above description.Here cannot give exhaustive to all embodiments.Every belong to technical scheme of the present invention the apparent change of amplifying out or variation be still in the row of protection scope of the present invention.
