Autoclaved sand-lime bricks manufactured by using building waste materials and crystal glass solid waste and manufacturing method thereof

Abstract

The invention relates to a method for manufacturing autoclaved sand-lime bricks manufactured by using building waste materials and crystal glass solid waste. The manufacturing method comprises the following steps: (1) enabling the building waste materials and fine sandstone to pass through a jaw crusher and a grinder, and screening a mixture by using a drum screen so as to obtain a building waste material and fine sandstone mixed waste materials; (2) blending the crystal solid waste with lime or carbide slag waste materials and the ground building waste material and fine sandstone mixed waste materials, synthesizing, quantitatively conveying to a double-horizontal mixer, adding water, carrying out forced stirring, feeding into a slaking silo, carrying out slaking reaction, and discharging out of the slaking silo; (3) sequentially passing through a vertical type forced grinder and a running wheel machine, feeding into a distribution bin of a forced pressing machine, distributing the materials to a mold, carrying out compression molding, and demolding to a working surface so as to obtain the mold bricks; and (4) sending the mold bricks to an autoclave, feeding air, heating, keeping constant temperature for several hours, discharging air and taking the bricks out of the autoclave, and maintaining the finished products for 6-10 days for use. The method has the characteristics of waste material utilization, energy conservation, soil conservation, environmental protection and sustainable development.

Description

technical field [0001] The invention relates to a method for producing autoclaved lime-sand bricks by using solid waste materials. Background technique [0002] In Pujiang, known as the capital of crystal, the processing and sales of crystal materials have become one of the main sources of income for thousands of households. Its vigorous development has enriched the majority of peasant brothers, cultivated a large number of social talents, and also promoted the development of logistics, transportation, packaging and other related industries, and promoted the social and economic development of Pujiang. However, due to the characteristics of the crystal industry, such as low technical level requirements, many geographical distribution points, large quantities, and wide areas, the distribution of the entire industry is unreasonable; the processing of crystal materials in Pujiang County is mainly in the form of family workshop production, resulting in Most of the crystal proces...

Problems solved by technology

However, with the increasing number of crystal processing workshops, more and more crystal processing households have spread to the countryside, which has brought great difficulties to the supervision of the environmental protection department, resulting in littering of crystal waste and waste water. , making the originally verdant and lush hills and forests decadent, the fields full of crops without harvest, and the crystal clear river with sewage flowing across

At the same time, the noise generated during the processing has seriously affected the lives of the surrounding residents and caused many social conflicts such as neighborhood disputes.
