Description
Technical field
The present invention relates to a kind of mixer, particularly a kind of mixer that is used for the carbon fiber mixture stirring.
Background technology
In the carbon fiber reinforced concrete goods, whether carbon fiber and cement are dispersed in the carbon fiber reinforced concrete is the key that causes the alert and resourceful performance quality of carbon fiber reinforced concrete.Because carbon fiber belongs to fragile material, if adopt wet type to stir, promptly add water and stir, two kinds of situations then may occur: one, mixing time is long, and carbon fiber easily produces fracture; Mixing time is too short, and then the carbon fiber skewness can cause alert and resourceful performance reduction of carbon fiber reinforced concrete or concrete strength not to reach requirement.And the method for traditional stirring carbon fiber reinforced concrete be with mixing time as the major control index, but this control is what be difficult to grasp.Equally, mixing time is too short, and it is inhomogeneous that carbon fiber disperses, and mixing time is long, and the carbon fiber phenomenon that fractures is serious, so the normal method of adding dispersant that adopts stirs.The researcher obtains when analyze adopting this stirring means: when the increase along with mixing time, to the CFCC of different carbon fiber content, the Changing Pattern of the carbon fiber coefficient of dispersion is consistent, promptly increase earlier, and reach maximum, after reduce suddenly, increase again at last; The corresponding coefficient of variation is just opposite, is to reduce earlier, reaches minimum of a value, after increase again, reduce again at last.The coefficient of dispersion and the coefficient of variation have reflected carbon fiber dispersed uniform degree in cement based to a certain extent.Therefore the whipping process of above-mentioned CFCC can be divided into three phases: (1) carbon fiber and cement meet, and sneak into mutually, because heterogeneous body becomes the mixture of certain uniformity gradually, the coefficient of dispersion is extremely maximum by zero; (2) along with the adding of cement, carbon-fiber cement compound denseness becomes big uniformly, and intergranular friction power strengthens, and stirring resistance increases, and the stirring of continuation makes fiber begin to assemble agglomerating, pencil, and fibre length diminishes; (3) prolong with mixing time, the fibrous fracture aggravation, agglomerate, bundle fiber are stirred the machine blade and break into very little group, bundle, and it is littler that fibre length becomes, and along with the aggravation of fiber breakdown, the coefficient of dispersion begins again to increase.In addition, in the method that adds dispersant, must earlier carbon fiber and water be mixed and stirred, how many consumptions of water has influence on dispersion effect, water consumption is many more, dispersion effect is good more, and the consumption of water is very low in the high-strength concrete, therefore, adopts to add dispersant and carry out stirring method and be difficult to make high-intensity concrete product.
Summary of the invention
At above-mentioned situation, the purpose of this invention is to provide and a kind ofly can evenly mix and stir the mixer that carbon fiber in the concrete and cement do not influence the alert and resourceful characteristic of concrete product again.
For achieving the above object, a kind of mixer that is used for carbon fiber mixture of the present invention comprises support, expansion bearing on this support rotating cage and be arranged on charging basket in this rotating cage.
For implementation structure optimization, reach not damaged and efficiently mix and stir, its further step is:
Described rotating cage comprises a pair of runner that is provided with wheel rim, spoke and the cage grid that are connected two runners and the fulcrum that is fixed in the runner center.
Described cage grid are fixed in the wheel rim place of two runners by the grizzly bar that is parallel to each other.
Described grizzly bar is provided with the movable cage door of opening.
The end of described fulcrum is provided with crank.
The root of described fulcrum is provided with bearing and bearing block.
Described bearing block is half-moon-shaped and adapts on the support.
