Compared with prior art, beneficial effects of the present invention are as follows：
1）The present invention provides a kind of construction technology of super-light aggregate foam concrete by above-mentioned technical proposal, ultralight to provide
The blending amount gathered materials, further improves the thermal property of foam concrete.It is known, required for the production mixing of foam concrete
The ratio of mud is generally than larger, and typically more than 0.5, in the case where meeting the ratio of mud, foam could effectively be connect with slurry
Touch, so that well mixed, it is ensured that product quality.But the ratio of mud is big, slurry viscosity is low, becomes desaturation, it is impossible to effectively wrap up
Firmly super-light aggregate, super-light aggregate is uniformly mixed into as problem.Therefore, in order that with super-light aggregate, improving foam concrete
Thermal property, current common solution is to reduce the ratio of mud of foam concrete, improves slurry viscosity, so as to wrap
Wrap super-light aggregate.And such solution there will naturally be problems with：One is that gained super-light aggregate foam concrete is sticky,
Original pumping equipment can not be applicable, and pumping load is big, taken out slurry difficulty and become big, be unfavorable for being smoothed out for construction operation；Two are
The ratio of mud is small, and the mixing uniformity of foam and slurry is difficult to control, and the quality of product will be affected.Super-light aggregate bubble of the present invention
The construction technology of foam concrete is to separate the preparation of foam concrete and the mixing of super-light aggregate, on the one hand, remain able to adopt
The production of foam concrete is carried out with existing equipment, without transforming original Foamed concrete producing equipment, load is pumped
Influenceed Deng the blending not by super-light aggregate, the production of original foam concrete is unaffected, the performance of foam concrete can be carried out
It is adjusted flexibly；Two are, increase mixing and blending machine, the foam concrete and super-light aggregate that existing equipment is produced are in mixing and blending machine
In be stirred mixing, so according to production equipment and product parameters etc. the need for, matching pumping system can be set,
Flexibility is improved, while the mixing uniformity of foam and slurry will not influenceed by super-light aggregate, it is only necessary to is improved and is mixed
Super-light aggregate is uniformly mixed into foam concrete by the structure of machine, and process complexity is substantially reduced.
2）It is of the invention according to the characteristics of super-light aggregate for the super-light aggregate foam concrete construction technology after improvement, with
And the performance of foam concrete etc., mixing and blending machine is improved as follows：One is that mixing component is improved, existing routine
Mixing component is usually that mixing arm is added on helical blade, or helical blade, but can not all solve the floating of super-light aggregate and ask
Topic.Mixing component includes helical blade in the present invention, and the helical blade is connected by dowel with agitating shaft, and in helical-blade
Baffle plate is added between piece, the distance of the distal face of the baffle plate to the agitating shaft surface is maximum at least equal to the helical blade outer
/ 2nd of footpath, so during mixing component is stirred, baffle plate can be in a certain position by foam concrete
And/or super-light aggregate is pressed in secondary mixer, and it is lighter plus super-light aggregate, on this basis, according to secondary mixing
The structure of device, the inwall apart from secondary mixer that the distal face of baffle plate can be designed more recently, the preferred distal end of baffle plate
Face is equal to or less than the particle diameter of super-light aggregate to the distance between the secondary mixer inwall, pushes effect more notable.Two
It is that the width of helical blade is improved, the width of original helical blade is consistent, for super-light aggregate and foam coagulation
Helical blade is designed as width by the mixing of soil, DeGrain, the present invention, while the internal diameter of the helical blade
Equal everywhere, i.e., internal diameter keeps constant, and only external diameter can be increasedd or decreased in change using gradual, or width alternating, excellent
In choosing, unit pitch, more than the 3/1 of helical blade is wide panel, and remainder is narrow panels, and baffle plate is connected to spiral shell
Between the wide panel of vane piece, the width so due to helical blade, in whipping process, compound same point by
Power is uneven, it is easier to occurs flow direction change, flowing is produced, so as to strengthen mixed effect.
3）By above-mentioned improvement, the present invention not only solves super-light aggregate and is easy to the difficulty that floats, wraps up well, and stirring is not
Uniform the problems such as, super-light aggregate is enabled to uniformly to be mixed with foam concrete, and super-light aggregate can be significantly improved
Blending amount so that the addition of super-light aggregate can reach 80 ~ 90%.
