Fiber concrete additive fiber smashing device

Abstract

The invention relates to the technical field of fiber concrete additive fiber smashing, in particular to a fiber concrete additive fiber smashing device. The device comprises a supporting frame, a smashing mechanism and a stirring mechanism, the supporting frame is of a [-shaped structure with a downward opening, and the smashing mechanism and the stirring mechanism are sequentially installed in the supporting frame from top to bottom. Through cooperation of the smashing mechanism, the stirring mechanism and a grinding plate, the three-stage smashing effect on glass fibers is achieved, meanwhile, the smashing efficiency of the glass fibers is improved, the problem that the glass fibers and cement base materials are difficult to evenly mix due to the fact that the smashing effect of single-time smashing of the glass fibers is poor is solved, meanwhile, the adhered glass fibers are scraped through a material scraping plate and a scraping plate in the smashing mechanism and the stirring mechanism respectively, so that the problem that the glass fibers are accumulated on a smashing roller and a stirring barrel to influence the smashing effect of the smashing roller and the stirring barrel on the glass fibers is solved.

Description

technical field [0001] The invention relates to the technical field of fiber pulverization of fiber concrete additives, in particular to a fiber pulverization device of fiber concrete additives. Background technique [0002] Fiber-reinforced concrete is a general term for composite materials composed of fibers and cement base materials (cement stone, mortar or concrete). The main varieties of fiber-reinforced concrete are steel-fiber-reinforced concrete, glass-fiber-reinforced concrete, plant-fiber-reinforced concrete, and high-elastic-modulus synthetic-fiber-reinforced concrete. , glass fiber concrete is a composite material composed of glass fiber and cement base material. Glass fiber in glass fiber concrete is an inorganic non-metallic material with excellent performance. Before the glass fiber is added to the cement base material, the glass fiber needs to be crushed , so that the glass fiber can be quickly mixed with the cement substrate.

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, the following problems may occur in the process of crushing the fiber concrete additive fiber: 1. When the glass fiber is crushed, the glass fiber is only crushed once and then sent to the cement base for mixing. , the single crushing of glass fiber is prone to the phenomenon that the crushing effect of glass fiber is not good, which leads to the formation of agglomeration of glass fiber when it is mixed with cement base material, and it is difficult to achieve the effect of uniform mixing

[0004] 2. The glass fiber is easy to adhere to the side wall of the crushing roller and the mixing barrel during the crushing process. The above phenomenon will easily affect the crushing effect of the crushing roller and the stirring barrel on the glass fiber
