Detailed description of the invention
Below in conjunction with specific embodiment, the utility model is described in further detail.
An automation feed system for Mold for Plastics binder blending cylinder based on its top feed, as shown in Figure 1, 2, comprises topThe Mold for Plastics binder blending cylinder of portion's charging and side's disposed thereon dosing device;
The Mold for Plastics binder blending cylinder of described its top feed comprises the cylindrical shell 1 of vertical setting and is arranged on entering of its topHopper 2; The top of described cylindrical shell is provided with the carrier gas distributor 3 of round platform tubular, and this carrier gas distributor 3 is by interior cylindrical shell 1 partBe divided into the carrier gas pre-distributor 4 on top and the dilution zone 5 of bottom; On described carrier gas pre-distributor 4 walls, be provided with tangentiallyThe carrier gas inlet 6 of gas; The round platform bus of described carrier gas distributor 3 and the angle of axis are 25 ° ~ 45 °, at this carrier gas distributor 3On wall, be evenly laid with some uniform flows hole, the cutting of tangent and the tangential and carrier gas inlet 6 of each uniform flow hole and carrier gas distributor outer wallTo identical; In the middle of described carrier gas distributor 3, is provided with feed pipe 7, this feed pipe one end is communicated with feed hopper 2, the other end andDilution zone 5 is communicated with; Described 5 bottoms, dilution zone are provided with discharge nozzle 8, for discharging the molding compound after blending.
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%.
