AI Technical Summary

Technical Problem

Traditional stirring equipment is difficult to flexibly adjust for different concentrations of alkali-activated materials, resulting in difficulty in effectively removing bubbles at low and medium concentrations, and easy generation of bubbles at high concentrations, which affects the density and mechanical properties of the mixed liquid.

Method used

A device for preparing alkali-activated materials that can replace cement was designed, including a base, a preparation cylinder, a stirring mechanism, and a vibration component. By switching between inclined stirring blades and flat stirring blades, combined with a partition component and a vibration component, efficient stirring and defoaming at different concentrations can be achieved.

Benefits of technology

The stirring mode can be flexibly adjusted according to the material concentration. At low or medium concentrations, the inclined stirring blades diffuse to the inner wall of the stirring chamber and remove bubbles. At high concentrations, the flat stirring blades move up and down to reduce foaming, thereby improving the preparation quality and applicability.

Abstract

The invention discloses equipment and a method for preparing an alkali-activated material capable of replacing cement, relates to the technical field of preparation of alkali-activated materials, and aims to solve the technical problems that a mixed solution is easy to foam and difficult to eliminate. Comprising a base, a preparation cylinder arranged on the upper surface of the base, a partition ring arranged in the preparation cylinder, a vibration cylinder arranged in the preparation cylinder, a stirring mechanism arranged in the preparation cylinder, a partition assembly and a vibration assembly. The preparation method realized by the equipment can flexibly adjust the stirring mode according to the concentration of the alkali-activated material: when low-concentration or medium-concentration mixed liquid is treated, the bubble-containing mixed liquid is diffused to the inner wall of the stirring cavity by virtue of the inclined stirring blades, and bubbles are effectively removed by virtue of the vibration assembly after being separated by virtue of the separation barrel, so that the materials are uniformly mixed, and bubble residues are reduced; when high-concentration mixed liquid is treated, the plane stirring blades are in contact with the liquid level and move up and down in a reciprocating mode to disturb the mixed liquid, annular wave diffusion is formed, and therefore the foaming phenomenon in the stirring process is reduced.
