The specific embodiment
In order to understand the utility model better, below in conjunction with embodiment and accompanying drawing the technical solution of the utility model is described further, referring to Fig. 1 to Fig. 5:
Press the efficient combined-type mixer that the utility model is implemented, include frame 4, tank diameter 1 is fixed on the frame 4 with slush pump 6, and frame 4 bottoms are equipped with wheel 5, convenient moving.The inside of tank diameter 1 is cavity structure, and its top offers charging aperture 13, and charging aperture 13 porch are equipped with is convenient to disperse cement to make it reinforced uniform material dispersion awl 12, and tank diameter 1 bottom offers discharging opening and is connected with the suction inlet of slush pump 6.Vortex generator 2 is installed in tank diameter 1 top and is connected with slush pump 6 outlets through circulation pipe 11, circulating valve 10.Stirring core 3 is fixed on tank diameter 1 bottom and constitutes some flow-guiding channels with tank diameter 1 taper bottom surface.The outlet of slush pump 6 is connected with circulation pipe 11 and discharge nozzle 8 by threeway 7, and the flow of circulation pipe 11 and discharge nozzle 8 is respectively by circulating valve 10 and bleeder valve 9 controls.
As Fig. 2, the vortex generator of present embodiment is communicated with circulation pipe 11 by injector 16 and forms, injector 16 includes playpipe 14 and venturi nozzle 15, playpipe 14 is the Z font that is symmetrically distributed along the tank diameter cross-sectional circumferential, playpipe 14 centers are connected circulation pipe 11 ends, venturi nozzle 15 connects two ends of playpipes 14, like this playpipe 14 ejection slurries through venturi nozzle 15 along same direction clockwise or counterclockwise in the tank diameter 1, thereby the formation eddy current.
In Fig. 3, the stirring core 3 of present embodiment is combined by last cone 17 and following cone 18, be welded with eight on last cone 17 and following cone 18 side surfaces respectively and go up guide vane 19 and following guide vane 20, last guide vane 19 and following guide vane 20 are vortex-like line structure, and rotation direction is opposite, and is that axis is equally spaced along circumference to stir core 3 center lines.
The course of work of the present utility model is: open circulating valve 10, close bleeder valve 9, successively water and cement are joined in the tank diameter 1 by charging aperture 13, cement disperses to be evenly distributed in tank diameter 1 top under awl 12 effects at material, starting slush pump 6 sucks bottom water mud and is driven in the vortex generator 2 through circulation pipe 11, the cement mortar on tank diameter 1 top forms strong eddy current under vortex generator 2 jet-actions, impel the cement mortar of tank diameter top and bottom evenly to mix, at this moment, the venturi nozzle 15 inner local decompressions that produce, cause playpipe 14 and near the venturi nozzle 15 cement mortar to be drawn into continuously in the venturi nozzle 15, the velocity gradient of venturi nozzle 15 high speed slurries produces the shearing force of fragmentary cement granules aggregate, strengthened mixing effect, meanwhile, the secondary stream that is produced by eddy current promotes the cement granules aggregate to the place's gathering of tank diameter 1 bottom centre, running into stirring core 3 back aggregates owing to 19 shear actions of guide vane on being subjected to are torn fragmentation, simultaneously, the cement grout that flows downward forms eddy current once more under the effect of last guide vane 19, to around scatter, and be drawn into rapidly in the flow-guiding channel that the following guide vane 20 that stirs core 3 and tank diameter 1 taper bottom surface constituted, cement mortar forms strong eddy current again and is sheared by guide vane 20 down once more.Cement mortar is so constantly circulation stirring in mixer, after stirring, opens bleeder valve 9, closes circulating valve 10, and cement grout is discharged to the job site fast by discharge nozzle 8.The bubble that is produced in cement mortar circulation whipping process escapes in the atmosphere by discharging opening 13.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalence of being done according to the utility model claim changes, and still belongs to protection domain of the present utility model.
