Description
Technical field
The present invention relates to a kind of high-performance quick generator for foam of making cellular concrete product, belong to construction material manufacturing and construction machine field.
Background technology
High-performance quick generator for foam is a kind of machine of producing foam concrete brick and/or foam concrete block and/or foam concrete insulating, after foam that high-performance quick generator for foam is made and cement slurry or concrete sand slurry or pulverized fuel ash cement slurry mix, obtain foamed cement slurry or foam concrete mortar body or foam pulverized fuel ash cement slurry.Foamed cement slurry or foam concrete mortar body or foam pulverized fuel ash cement slurry moulding by casting are obtained foam concrete brick and/or foam concrete block, or foamed cement slurry or foam concrete mortar body or foam pulverized fuel ash cement slurry directly constructed obtain the foam concrete insulating in the house top layer.The quality of foam concrete brick and/or foam concrete block and/or foam concrete insulating is except outside the Pass having with foam concrete density, foam stability, also relevant with uniformity, the cell diameter of foams, the uniformity of foams is relevant with the performance and the foam-generating method of foam maker with cell diameter.The production method of existing cellular concrete product mainly contains four kinds: first method is earlier the solution that contains blowing agent to be mixed with concrete mortar, the stirring vane that re-uses low-speed mixer is directly squeezed into air in the slurry and is foamed, and directly obtains gas-liquid-solid three-phase froth concrete mortar.The shortcoming of this method has: 1. the cell diameter of foams changes greatly, and the pore size distribution range of cellular concrete product is big, and its intensity is reduced; 2. the stirring vane mixing speed is slow, the little air of introducing in the concrete mortar, and expansion rate is slow, and the production efficiency of cellular concrete product is low; 3. blowing agent can not fully foam, and the blowing agent utilization rate is low.Second method is earlier the solution that contains blowing agent to be mixed with concrete mortar, and the stirring vane that re-uses quick mixer is directly squeezed into air in the slurry and foamed, and directly obtains gas-liquid-solid three-phase froth concrete mortar.Second method is compared with first method, the production efficiency of cellular concrete product is improved,, make the varying aperture of the foams that obtain big because its foam process is similar with first kind, the pore size distribution range of cellular concrete product is wide, and the intensity of cellular concrete product is reduced; Blowing agent can not fully foam, and causes the blowing agent utilization rate to reduce.The third method is earlier the solution that contains blowing agent to be pressurized to certain pressure, then foam chamber mesohigh water with pattern and pressure-air mix, broken, foaming, obtain foams.It is most advanced that this method prepares the technology of foam, and the production efficiency height is effective, but because the operating pressure height, and the specification requirement of equipment is improved, and complex manufacturing improves production cost, has influenced the popularization of its technology.The 4th kind of method is by foaming machine the liquid that contains blowing agent to be mixed with compressed air earlier, make solution-air two-phase foams, again foams and concrete slurry are mixed, make the foam concrete slurry at last, promptly getting cellular concrete product after the cast of foam concrete slurry.The cellular concrete product that this method obtains all increases than first and second kinds on production efficiency and serviceability, but because the difference of its foaming tube and/or foam chamber internal structure, make to be entrained with not the fully foaming agent solution of foaming in the foams, the utilization rate of blowing agent is reduced; In addition, also make the bubble diameter size of the foams that make and distribution difference thereof bigger, directly have influence on the performance of cellular concrete product.
