Title of the articleA method and apparatus for making colored concrete
Abstract.The article proposed method and device for the preparation of colored concrete. The method is that the container loaded with material reported complex spatial motion with an irregular per revolution angular velocity. The amplitude of change of the angular velocity in a single revolution, selected in the range of 0,1...0,9 the value of the average speed and the frequency of the change within 120...290 min-1. The method is implemented by a device consisting of two coupled four-bar spatial mechanisms with crossed axes of hinges and two tanks, mounted on crank mechanisms. Sides of the housing, connected with the leading cranks have a constant angular velocity, and other parties associated with the slave cranks, a variable angular velocity, with capacity have opposite spin. As a result, they create the same in magnitude, but opposite in sign to the inertia moments, which balance each other on the bed and do not apply. Under the action of complex, uneven spatial movement and an additional inertial effect intensify preparation of a colored concrete mix is balanced and at the same time the device. A method and apparatus are protected by copyright certificates on the invention. Production test preparation colored concrete one hundred percent showed the uniform distribution of pigments of the dye throughout the volume of the mixture. Multi-function device in addition to mixing the concrete mix showed high technical and economic indicators in other processes: mixing of different feed products, seed treatment, washing of root and tuber, grinding the seeds of sugar-beet haulage, skins of fur animals, etc.
Keywords.cranks, connecting rod, spatial mechanism, mixing, concrete color mix.
