Production line and method of non-autoclaved light building blocks

Abstract

The invention discloses a production line and method of non-autoclaved light building blocks and belongs to the field of building materials. According to the production line and method of the non-autoclaved light building blocks, the technical problems that equipment cost input for production of existing autoclaved aerated concrete building blocks is enormous, and production energy consumption is large are to be solved; and a discharging port in the bottom of a mixing tank is formed above the end head of a dry powder conveying belt, a feeding port of a pouring system is correspondingly formed below the other end head of the dry powder conveying belt, and a guide rail set and a cutting system are installed in the direction perpendicular to a first guide rail. The method comprises the following steps that water is added into the pouring system, then a reinforcing agent and a foam stabilizing agent are added, and stirring is evenly conducted; then a dry powder mixture is added through the dry powder conveying belt, and stirring is evenly conducted; and finally, a foaming agent is added, stirring is conducted, then a mold jacket assembly is injected, curing is conducted for six hours or more, demoulding is conducted, longitudinal cutting is conducted after transverse cutting is conducted, after rotating by 90 degrees, longitudinal cutting is conducted again, and the non-autoclaved light building blocks are obtained. The production line and method are used for producing the non-autoclaved light building blocks.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a production line and a production method of autoclaved lightweight blocks. Background technique [0002] Autoclaved aerated concrete blocks have been widely used wall materials. The existing autoclaved aerated concrete block products use cement and lime as the main cementitious materials, supplemented by mineral powder and fine sand as filling materials. Aluminum powder is a gas-generating material, which is made through grinding, stirring, gas-generating, molding, and high-temperature and high-pressure curing. The materials used in the entire production process are all natural materials, and natural materials are short-term non-renewable materials. Excessive development will seriously affect the natural environment, and the cost of equipment used in production is huge, and the production energy consumption is large.
