A kind of air-entrained concrete block forming preparation technology

Abstract

The present invention relates to a process for forming and preparing aerated concrete blocks, in particular to a demoulding and cleaning device for preparing and preparing aerated concrete blocks, which includes a lifting and demoulding mechanism, an electric switching turntable, a cleaning walking mechanism, a wall-adhering mechanism and Cleaning mechanism; the lifting and demoulding mechanism includes a device plate, two demoulding cylinders vertically fixed on the top of the device plate, four guide posts distributed vertically and fixedly at the bottom of the device plate in a rectangular shape, a vertical The square elevating frame arranged on the four guide columns and the four supporting mechanisms arranged one-to-one on the four side wall ends of the elevating frame are arranged in a straight slide manner, and the cleaning mechanism includes an L-shaped fixing frame and a cleaning drive motor , cleaning roller and passive shaking mechanism; the device involved in the process provided by the invention can complete the general demoulding operation, and can automatically complete the cleaning of the slurry on the inner wall of the mold frame in time after the demoulding is completed, so as to avoid the dryness of the slurry , reducing the difficulty and trouble of mold frame cleaning.

Description

technical field [0001] The invention relates to the technical field of production and processing of building materials, and specifically proposes a molding preparation process of an aerated concrete block. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermal insulation, good fire resistance, nailable, sawable, planable, and has certain earthquake resistance. As early as the early 1930s, China began to produce this product, and it was widely used in high-rise frame structure buildings. It is an excellent new building material. Compared with traditional concrete blocks, aerated concrete blocks have the advantages of light weight, high strength, good thermal insulation performance, good shock resistance, good machinability, high temperature resistance, and good sound insulation, so they are widely used in the field of modern building materials. been promoted and used. [0003] The production process...

AI Technical Summary

Problems solved by technology

[0003] The production process of aerated concrete blocks generally goes through raw material preparation, raw material storage, steel mesh processing, batching mixing, slurry pouring, static maintenance, embryo demoulding, slitting, heat preservation and autoclaving, and exiting the kettle. In the process of demoulding the embryo body, the aerated concrete body formed by static stop maintenance and expansion is separated from the frame of the forming mold. In the production process of the aerated concrete block, in order to improve the demoulding The smoothness of the mold and the integrity of the outer wall of the aerated concrete body after demolding should be ensured as much as possible. The mold frame used for forming generally needs to clean the inner wall after use, and spray oil on the inner wall after cleaning. In the production process, it is inevitable that slurry residue will be formed on the inner wall of the mold frame. In the traditional processing process, the slurry on the inner wall of the mold frame is often not cleaned in time after the demoulding is completed, so that the slurry often dries up and increases. Increased the difficulty and trouble of follow-up cleaning
