Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
Based on an automation feed system for pre-heated Mold for Plastics binder blending cylinder, as shown in Figure 1 and Figure 2, comprise preheatingFormula Mold for Plastics binder blending cylinder and side's disposed thereon dosing device;
Described pre-heated Mold for Plastics binder blending cylinder comprises feed hopper 2 and the cylindrical shell 1 vertically arranging; Described cylindrical shellTop is provided with the carrier gas distributor 3 of round platform tubular, and this carrier gas distributor 3 becomes the carrier gas on top to divide in advance cylindrical shell 1 interior separationThe dilution zone 5 of cloth device 4 and bottom; On described carrier gas pre-distributor 4 walls, be provided with the carrier gas inlet 6 of tangential admission; DescribedThe round platform bus of carrier gas distributor 3 and the angle of axis are 25 ° ~ 45 °, are evenly laid with some on these carrier gas distributor 3 wallsUniform flow hole, tangent with carrier gas distributor outer wall and the tangential and carrier gas inlet 6 in each uniform flow hole tangentially identical; Described feed hopper2 are arranged on a side of cylindrical shell 1, are communicated with dilution zone 5 by feed pipe 7; Described 5 bottoms, dilution zone are provided with discharge nozzle 8, forMolding compound after blending is entered to plastic molding machine; On the outer wall of described cylindrical shell 1, be provided with heater, for giving dilution zoneMolding compound in 5 and carrier gas heating.
Described dosing device comprises feed belt device 9 and several sides' disposed thereon material container 10;Described feed belt device 9 is made up of driving wheel 91, driven pulley 92 and belt 93, and belt 93 ringwise, is placed on driving wheel 91Outside driven pulley 92, for molding compound being delivered to feed hopper 2; Described material container 10 is inverted tank shape, for holdingDifferent molding compounds or flexibilizer, its upper end has charging door, under lower end, has ingredients mouth, and ingredients mouth place is provided with batching and controlsValve, for controlling the amount of molding compound of discharge.
For convenient inlet amount and the load of regulating, on described discharge nozzle 8, be provided with discharge valve, for controlling blendingAfter the discharge rate of molding compound; On described feed pipe 7, be provided with material inlet valve, for controlling the molding compound that enters dilution zoneAmount.
Uniform flow hole size and percent opening directly affect mechanical strength and the carrier gas of distributor and pass through speed and the resistance of aperture.If hole is many or diameter is excessive, can make the mechanical strength of distributor reduce, carrier gas is little by the flowing velocity in hole, StirringKinetic energy deficiency can not reach expected effect, otherwise if hole is too small or very few, carrier gas is large by the resistance of distributor, disappearsThe energy of consumption is just large. Suitable bore dia and percent opening both can ensure that carrier gas, by the flow velocity of aperture, had enough kinetic energy, againCan make the dispersion fluidisation shape of gas-solid formation disperse in reactor body. Given this, finally determine described uniform flow bore dia be 2～4mm, and the uniform flow hole gross area is 4～8% of carrier gas distributor 3 internal surface areas, preferably 5%.
