Embodiment Construction

[0011] attached figure 1 . The structure schematic diagram of the present invention is given, and the arrows in the figure indicate the direction of material flow. attached figure 2 The structure of the vertical stirrer is given.

[0012] Working process of the present invention:

[0013] A certain amount of cement, aggregate (sand) and chopped fiber (surface-treated carbon fiber) are put into three storage hoppers 1 respectively, and under the action of gravity, they fall into the frequency conversion induction motor 3 whose instantaneous speed is controlled by a computer. The screw feeder 4 driven by the gear 2 is fed into the vertical agitator 6 through the feeding pipe 5, and the material entering the vertical agitator 6 is stirred by gravity and the stirring rod 7 and the stirring blade 23 (stirring rod) rotating at a high speed (1400r / min). 7 is driven by the three-phase AC asynchronous motor 13 controlled by main controller 17 through belt 9, and 12 is under the sti...

Abstract

A gradient pugging apparatus for preparing the cement-based materials, such as the gradient functional concrete or short fibres reinforced cement-based gradient functional material is composed of vertical stirrer, horizontal pugging cabin, water flow regulator and more than two storage tanks, which consists of feed hopper, frequency-varying induction motor, speed-varying gears, screw feeder and discharge pipe.

Description

Technical field: [0001] The invention relates to a cement-based material gradient mixing instrument. Background technique: [0002] As the most widely used building material, cement-based materials have played a significant role in the improvement of human civilization and living conditions in the 20th century, and there is no sign of being replaced by other materials in the next hundred years. Cement-based materials have the advantages of wide source of raw materials, low cost, convenient processing and manufacturing, high compressive strength, and good durability. full play of its role. The concept of functionally gradient materials provides a new way to prepare materials with composite functions, special functions or excellent mechanical properties. At present, functionally graded materials have become a reality in the fields of fine functional ceramics, metal / ceramic composite materials, and metal alloy materials. However, due to the particularity of the structural co...
