Preparation method of light foam concrete and its main machine

Abstract

The invention discloses a preparation method of lightweight foamed concrete and its main engine. The preparation method uses a manual regulating valve and an adjustable electronic valve in the measurement and mixing of foaming agent, water and compressed air for foam preparation. Combined control technology; in the mud delivery technology that solves the mixing of mud and foam, the large pneumatic diaphragm pump regulated by the manual control valve is used to transport the mud, and the lightweight foam concrete is directly transported to a certain height or a certain distance. The main feature is on-site, and the main feature of the main machine is that it integrates three parts, the compressed air supply device, the foam preparation device and the mud and foam mixing device to prepare the finished lightweight foam concrete device, into one casing. The preparation method has the characteristics of accurate measurement of raw materials, stable foam quality, and good quality of the foam concrete; the host machine has the characteristics of compact and reasonable structure, convenient on-site use, convenient control and adjustment, and the like.

Description

technical field [0001] The invention relates to a preparation method of lightweight foam concrete and a main machine thereof, belonging to concrete preparation technology and construction machinery technology. Background technique [0002] Lightweight foamed concrete (hereinafter referred to as foamed concrete) is widely used as the surface construction material for building walls and roofs due to its advantages of light weight, heat insulation and sound insulation, or it is prepared by mold pouring. Quality insulation components. The said foam concrete is a kind of energy-saving and environment-friendly concrete at present, and has extremely broad application prospects. [0003] Mainly use cement as the cementitious material in existing, and in the said foam concrete technology of foam preparation, mainly there are following two problems: the one, in its foam preparation technology, because be according to blowing agent instruction manual , by manually mixing and diluting...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for preparing lightweight foamed concrete and its main engine, so as to solve the problems of inaccurate measurement of raw materials, unstable foam quality, and high foam damage rate in the pumping process. The technical problem that the quality of the prepared lightweight foamed concrete is difficult to guarantee, and it is suitable for on-site construction or factory preparation of the said foamed concrete member, and the needs of its host for easy movement and control.
