Description
Technical field
The utility model is related to a kind of civil engineering technical fields of Foam lightweight soil material preparation and construction.
Technical background
Foam lightweight soil has that light, intensity is suitable, fire prevention, heat preservation, sound insulation, easy for construction, energy conservation and environmental protection etc. are numerous
Advantage and noted by masses in engineering field, have a wide application field, more and more engineerings selections use foam light
Matter soil replaces traditional material and construction technology.It is even more to be made on a large scale using Foam lightweight soil in the man-made island project of Macao port
It, should by replacing lightweight aggregate concrete the problem of man-made island roadbed backfilling material reduction settlement after construction and as roofing heat insulating material
The Foam lightweight soil of project is always just measured up to as many as 230,000 sides.Cast-in-place foamed light soil is that cement mortar is mixed to form with aqueous foam
, in the case of material identical, the intensity of Foam lightweight soil depends primarily on its internal foam pore structure, therefore good
Foam is the key that prepare good quality froth light soil.Identical foaming agent can form the foam of different bubble diameters, the quality of foam
Quality depends primarily on the foam pattern of foaming machine.After being foamed due to foaming agent aqueous solution, with the thinning of liquid film of foam,
The foam that string bubble is bubble diameter bigger is influenced Foam lightweight soil inner hole structure, therefore foam initial stage bubble diameter is smaller by adjacent foam,
Foam is more lasting, and finally formed Foam lightweight soil pore structure is more advantageous.
One of foaming machine is mechanical foaming machine in the market at present, and principle is to drive meshed blade by motor
It carries out strong stirring and foaming agent aqueous solution is made to foam, the disadvantage is that：
1, using method of the motor with movable vane piece stirring foaming, motor needs to expend additional electric energy as power, energy consumption
It is larger.
2, using method of the motor with movable vane piece stirring foaming, equipment is more heavy, especially heavy-duty motor, dead weight
Greatly, device structure is complicated.
3, due to the presence of motor, there are Electrical Safety risk, foaming machine motor dimensions in the environment of cargo sweat liquid
Shield is difficult, and maintenance cost is higher.
4, the diameter of mesh determines the bubble diameter of foam on blade, can not prepare the other bubble of micro/nano level, prepared
Foam bubble diameter is larger, and easy string soaks the bubble of bigger, influences the pore structure and compression strength of Foam lightweight soil.
5, in order to enable foaming agent aqueous solution fully foams, foaming agent must foaming storehouse in stay long enough,
It is fully stirred, therefore bubbling efficiency is relatively low, is not suitable for large-scale application.
Foam lightweight soil application range is growing, and foaming agent has updated to the 4th generation compound foaming agent, still
The research of mating foaming machine is opposite to be lacked, in order to cope with the large-scale application in engineering, it is necessary to study a kind of foaming energy
Power is more preferable, energy consumption smaller, and foam theory is even more ideal, rational Novel foaming equipment.
Jet stream refers to fluid and is projected from nozzle, aperture, slit, or leans on mechanical driven, and with a plume of surrounding fluid blending
Body flows.The large Reynold number jet stream frequently encountered is usually the free turbulence constrained without Gu Bi.This turbulent jet passes through boundary
Surrounding fluid volume is sucked in and is constantly expanded by upper active turbulent closure scheme, and cocurrent is downstream.Jet stream is in water pump, steam pump, logical
Many technical fields such as wind turbine, chemical industry equipment and jet plane are used widely.Especially in sewage treatment field, jet stream
It is applied in the micro-nano aeration process of jet stream so that aeration bubbles bubble diameter reaches micro-nano rank so that oxygen in water
Amount greatly increases and is the currently the only technology that can accomplish micro-nano aeration steadily in the long term.
