Foam concrete production line and preparation method

Abstract

Foam concrete production line, including frame, controller, foam preparation mechanism, slurry preparation mechanism, mixing mechanism and conveying mechanism. The mixing mechanism includes a power chamber, an upper mixing chamber and a lower mixing chamber. The upper mixing chamber is equipped with a drainage hood. The upper mixing chamber is divided into a stirring chamber and a mixing chamber by the drainage cover; the stirring chamber is provided with a stirring shaft 1, a stirring shaft 2 and a fixed shaft, the fixed shaft is sleeved on the stirring shaft 2, and the stirring shaft is set on the fixed shaft, The lower end of shaft one has stirring blade one, the lower end of stirring shaft two has stirring blade two, the lower end of the fixed shaft is provided with a fixed plate, the fixed shaft has a foam channel, the fixed plate has a diffusion chamber and is provided with a number of foam holes, The foam produced by the foam production mechanism is discharged into the mixing chamber through the fixed shaft, and the cement slurry produced by the slurry production mechanism is discharged into the mixing chamber through the slurry feeding pipe, and the cement slurry and foam are stirred in the upper mixing chamber After mixing, it is discharged into the lower mixing chamber and mixed with auxiliary materials, and foamed concrete is obtained after molding and curing.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a foam concrete production line and a preparation method. Background technique [0002] Foamed concrete, also known as foamed cement, lightweight concrete, etc., is a new type of building energy-saving material that is waste-friendly, environmentally friendly, energy-saving, inexpensive and non-combustible. Lightweight concrete (foam concrete) is formed by introducing air or nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry according to the application needs through chemical or physical means, and after reasonable maintenance and molding, it is formed to contain a large number of small closed pores, and Concrete products of considerable strength. The production of lightweight concrete (foamed concrete) is usually prepared by mechanically preparing the foaming agent aqueous solution into a foam, and then adding the foam to the slurry composed of s...

Problems solved by technology

[0003] However, with the continuous development of foam concrete technology, the traditional foam concrete foaming method has limitations in flexibility and anti-cracking performance due to its different process methods and equipment, which is difficult to meet in actual production and life.
