Description
Technical field
This application involves a kind of small-sized plate form rubber blenders.
Background technique
China comes into the extensive road rehabilitation phase, generates a large amount of waste asphalt pavement material every year.Foamed asphalt
Regeneration techniques with the unique advantage of its " energy-saving and environmental protection, economy are significant " can Efficient Cycle utilize these materials.
Asphalt foaming be by air, atomization water and be heated to the pitch of certain temperature, while being passed into specific appearance
It is intracavitary, the physical change of a series of complex occurs, fossil bitumen volume is caused to increase rapidly, generates the bubble of similar spongelike structure
Foam pitch.The viscosity of foamed asphalt has significant decrease relative to the viscosity of plain asphalt, and has after mixing and stirring with mixture fine
Wrap up in attached performance, it can be achieved that the road constructions technology such as foamed asphalt regeneration, foamed asphalt warm mix, virgin material cold mixing.But foam drips
Blueness belongs to meta-stable product, there is only tens seconds, is stirring the needs " mixing and stirring in foaming " that mix and stir of plate form rubber (i.e.
It mixes storehouse inner edge sprinkling foamed asphalt and completes stirring before the state that foamed asphalt restores fossil bitumen while mixing and stirring mixture).Bubble
The quality and performance of foam asphalt are the premises of foamed asphalt regeneration techniques successful implementation.The construction of foamed asphalt regeneration techniques
Before, clearly optimal Mixture Ratio is needed, and guarantee that mixing goes out in a very short period of time and match homogeneous foam up to standard
Asphalt.The uniformity of plate form rubber directly determines the high-temperature stability of mixture, low-temperature cracking-resistance, durability
Etc. technical performances, and then determine bituminous pavement fatigue life.The position voidage that coarse aggregate is concentrated is excessive, bitumen content is inclined
Less, the harm such as pit slot and Moisture Damage easily occurs for bituminous pavement, can reduce the fatigue life of bituminous pavement；The position that fine aggregate is concentrated
Often bitumen content is on the high side, and voidage is too small, the harm such as will lead to the permanent deformation on road surface, and bellding occur.Therefore, it to obtain
The mixture of function admirable will also take into account stirring efficiency, this just proposes plate form rubber blender performance harsh
It is required that.
In bituminous mixture field, current research is all the large-scale blender that Engineering Oriented uses, and is dedicated to
The new structure of design blender, increase new function, and the small-sized plate form rubber blender used towards laboratory
Rarely has research.
Twin-shaft mixer is usually used in the stirring of concrete, asphalt, but the foam with " meta-stable " characteristic drips
It is green very different from pitch, think in a very short period of time to stir evenly mixture just more difficult.The knot of twin-shaft mixer
Structure parameter is more, and the complexity between parameter is contacted and influenced each other but also finding the structural parameters of most suitable foamed asphalt stirring
It becomes difficult.
It at present for the evaluation of asphalt mixed material agitator performance, is mainly measured by Marshall Test, Wu Facong
Uniform mixing mixes and stirs the angle of efficiency and stirring intensity to blender progress accurate evaluation.Since Physical Experiment can not be visited
Survey blender Different structural parameters to mixture uniform mixing, mix and stir the influence of efficiency and stirring intensity, market and research
In it is also limited because calculating cost always to this numerical simulation study or practical and flow in surface because being detached from market.
Summary of the invention
