Foamed concrete foam mixing device provided with blades

Abstract

The invention relates to a foamed concrete foam mixing device provided with blades. The foamed concrete foam mixing device comprises an initial mixing pipe and a conveying device, a foam generating mechanism and a cement paste mixing mechanism are connected to the front end of the initial mixing pipe, the back end of the initial mixing pipe is connected with the front end of the conveying device,the back end of the conveying device is connected with a foamed concrete output mechanism, the conveying device comprises a conveying pipe and a mixing shaft arranged inside the conveying pipe, the mixing shaft is movably arranged in the conveying pipe, the blades are arranged on the surface of the mixing shaft and are distributed in a multiple blade wheel manner, each blade wheel comprises a plurality of blades distributed evenly, a 45 degree-75 degree included angle is formed between each blade and the radial plane of the mixing shaft, the mixing shaft and the blades on the mixing shaft canfurther mix foamed concrete in the foamed concrete conveying process, and internal tiny bubbles are distributed more evenly.

Description

technical field [0001] The invention relates to concrete processing and transportation equipment, in particular to a foaming concrete mixing device provided with blades. Background technique [0002] Foamed concrete is a new type of building material formed by fully blowing the foaming agent to form a foam containing a large number of tiny bubbles, and fully mixing it with cement slurry. After the foamed concrete is cast in place or molded, a large number of closed pores will often be formed inside. , the building material has the characteristics of light weight, thermal insulation, sound insulation, etc., so it is more and more used in various engineering constructions, and its demand is increasing. [0003] However, the existing concrete processing and transportation equipment is designed for traditional concrete, and does not take into account the special needs of foamed concrete. Traditional concrete can be fully stirred to make the solute solution evenly mixed, but foa...

AI Technical Summary

Problems solved by technology

Traditional concrete can be fully stirred to make the solute solution evenly mixed, but foamed concrete cannot be vigorously stirred after the foam and cement slurry are mixed, mainly because the air bubbles mixed in the cement slurry may be damaged due to vigorous stirring, In turn, the resulting foamed concrete cannot meet the needs of actual construction due to insufficient air bubbles.
