Abstract
A multi-step concrete mixing technology for quickly preparing cement paste includes such steps as charging powder material, proportinoally mixing powder with water, stirring cement paste, proportionally mixing with aggregates, stirring again, and loading finished product in car. Its advantages are full hydrating, high strength of concrete, saving cement and low cost.
Description
Technical field
The present invention relates to a kind of build concrete stirring technique, particularly a kind of multi-step concrete stirring technology for fast grout preparation method in the concrete mixing is stirred.
Background technology
In available coagulation soil stirring technique, after water and cement, flyash weighing are good, just directly enter mixer and aggregate stirs, after water and cement, flyash weighing operation, there is not the mortar agitating procedure.Like this, water is not combined with cement, flyash, influences the aquation quality of cement, flyash.Because it is insufficient that the physical-chemical reaction of cement, flyash carries out, thereby reduce concrete quality.
And powder is directly to enter concrete mixer in the conventional process flow, and the aggregate charging aperture of mixer can not reach complete closed, and causes dust to be discharged in the air, has caused the pollution of environment.
Summary of the invention
The objective of the invention is to provides a kind of water that can allow fully be mixed with cement, flyash to the public, makes the combination reaction between cement, flyash and the water more complete, more can give full play to the adhesion of cement, flyash.Thereby improve the multi-step concrete stirring technology for fast grout preparation method of the concrete quality of finished product.
Below be that the present invention is the method that achieves the above object and adopted
The process of multi-step concrete stirring technology for fast grout preparation method is:
When after water and powder metering, carrying out the mortar stirring, carry out the aggregate metering, be only concrete then and stir product car-loading:
Described powder is cement, flyash, and described aggregate is sand, stone.
The concrete technical scheme of above-mentioned multi-step concrete stirring technology for fast grout preparation method as shown in Figure 1.
Feed: storage bin 1, conveyor screw 2 (but 1,21 group or several groups, store respectively and carry a kind or powdery binders such as several cement, flyash) powder is transported to weighing hopper 3.
Metering: water batch meter 4 measures corresponding water on request, match ratio requirement routinely in 3,4, and the water and the powdery binders such as cement, flyash that measure are placed in the mortar change-can mixer 9.
Mortar stirs: in change-can mixer 9, mixed uniform mortar through water and the powdery binders such as cement, flyash that measure by high-speed stirring.Concrete stirs: several aggregates in the aggregate bin 8 are placed into metering in the aggregate scale 7 in proportion, and the aggregate after the metering is sent in the concrete mixer 5 through conveyer 6.Send at aggregate and to open change-can mixer 9 bottom valves in the process, the mortar that stirs is put into concrete mixer 5.
Product car-loading: aggregate and mortar are after mixer stirs into high-quality concrete, and the concrete of packing into delivery truck is sent to each job site.
Quickly preparing cement paste method technology is meant: binder such as water through measuring in powdery binder measuring chute 3, the water batch meter 4 and cement, flyash and water are dropped in the change-can mixer 9 hydration reaction that mixes uniform mortar, cement, flyash through high-speed stirring to be carried out fully.Mortar reenters concrete mixer with the aggregate stirring method.
The mud agitating procedure is to be that vertical, concentric, twin shaft change-can mixer is born by an architectural feature.Basic structure is: the vertical machine that is meant is barrel-shaped, and charging is last, and discharging is following; Be meant that with one heart the high-speed stirred axle is concentric with the stirring at low speed axle; Twin shaft is meant that high-speed stirred axle and high speed leaf oar fix, and stirring at low speed axle and low speed leaf oar are fixed.Its detailed structure has been applied for the utility model patent protection separately.
Powder such as cement, flyash and water stir into oar through stirring the oar machine earlier, enter concrete mixer and aggregate again and stir.Stirring oar can be whole powders, also can be only to stir water and cement or cement and flyash.
Described aggregate is meant rubble or cobble.
The invention has the advantages that:
One, owing to increased the mud agitating procedure, the water after the metering and cement, flyash and other powder dropped into earlier stir the oar machine and stir, powder and water are stirred into oar drop into concrete mixer and aggregate stirring again.Powders such as cement elder generation and water are stirred into mortar, be transported to concrete mixer again and stir with aggregate, this new technology can make the binder in the concrete obtain sufficient aquation, and its adhesion is not fully exerted, thereby improves concrete intensity.Satisfying under the situation of requirement of strength, can save binders such as cement, reduce the concrete cost effectively.
Two, powder is stirred pulping by change-can mixer and enters concrete mixer again, concrete stirs charging aperture will no longer include the dust discharge, all be that totally-enclosed transmission does not have dust pollution yet in all processes before the change-can mixer discharging opening, thereby the dust discharge of having removed powder is fully polluted, and powder directly enters concrete mixer in the conventional process flow, the aggregate charging aperture of mixer can not reach complete closed, pollutes and cause dust to be splashed in the air.

The specific embodiment
As shown in Figure 1,
The process of multi-step concrete stirring technology for fast grout preparation method is: feed be with the powder in water and the fines storehouse 1 (cement, flyash) by fines conveying device 2 and water pipe respectively routinely ratio measure by metering device 3,4, the change-can mixer 9 that enters the mortar agitating procedure stirs, and then enter mixer 5 and stir with aggregate, be that aggregate is carried then, the aggregate metering, aggregate puts in storage.
Described quickly preparing cement paste technology is meant: mortar agitating procedure 9 is to be that vertical, concentric, twin shaft change-can mixer is born by an architectural feature.Basic structure is: the vertical machine that is meant is barrel-shaped, and charging is last, and discharging is following; Be meant that with one heart the high-speed stirred axle is concentric with the stirring at low speed axle; Twin shaft is meant that high-speed stirred axle and high-speed stirred leaf slurry is fixing, and the stirring at low speed axle is fixed with stirring at low speed leaf slurry.Its function is to stir out mortar fast, evenly, in large quantities.
Powder such as cement, flyash and water stir pulping through change-can mixer earlier, enter concrete mixer and aggregate again and stir.Stirring slurry can be whole powders, also can be only to stir water and cement, or cement and flyash.Described fines is cement, flyash etc., and aggregate is meant sand, rubble.
