Steel fiber dispersing machine for preparing fiber concrete

Abstract

The invention discloses a steel fiber dispersing machine for preparing fiber concrete. The steel fiber dispersing machine comprises a stock bin, wherein a feeding hopper is arranged on the side wall of the stock bin, the interior of the stock bin is divided into a material shifting cavity and a dispersing cavity by a partition plate, an output port of the feeding hopper communicates with the shifting cavity, a shifting device is arranged in the shifting cavity, a material outlet is formed in the bottom of the dispersing cavity, an vibrating assembly is fixed on the material outlet, a pluralityof shifting units are arranged on the periphery outer wall of the rotating shaft along the axis of the rotating shaft, a plurality of shifting tooth grooves are formed in the partition plate, each shifting unit is composed of a plurality of shifting teeth, the rotating shaft is rotated anticlockwise, when the shifting teeth drive the steel fibers to move to the vibrating assembly, and then the shifting tooth penetrate through the material shifting tooth grooves to be moved into the shifting cavity again so as to realize continuous stirring. According to the technical scheme, a conventional latticed screen is not adopted during dispersion, and a two-stage vibrating screen plate is designed, so that secondary dispersion of the steel fibers is realized, and bending or damage of the steel fibers in the dispersing process is avoided while blockage of the steel fibers is avoided.

Description

technical field [0001] The invention relates to a steel fiber disperser, in particular to a steel fiber disperser for preparing fiber concrete. Background technique [0002] Concrete is the most widely used building material in the civil engineering industry. It has the advantages of easy molding, high compressive strength, good durability, and low price. It is widely used in tunnels, bridges, roads, water ports, underground structures, etc. An irreplaceable building material for engineering construction. However, as a brittle building material, concrete's low tensile strength is still a major problem in its engineering application. [0003] The emergence of fiber reinforced concrete has successfully solved the problem of low tensile strength and toughness of concrete. As a high-performance concrete building material, fiber reinforced concrete has been widely used in the field of engineering construction in my country. When fiber-reinforced concrete is prepared, an approp...

AI Technical Summary

Problems solved by technology

The artificial dispersion method can only meet the small-scale preparation of fiber concrete in the laboratory. If large-scale concrete construction is carried out, the dispersion efficiency is low, the effect is not ideal, and time-consuming and labor-intensive. Therefore, mechanical dispersion must be used.

Existing conventional dispersing machines include drum type, centrifugal type and sieve drum rotating type, etc. The dispersing blades of the dispersing machine are very easy to bend or damage the steel fibers during dispersion, and the steel fibers are easy to block the grid screen.
