Embodiment 1

[0023] A method for manufacturing autoclaved lime-sand bricks by using construction waste and crystal glass solid waste, the method includes the following steps: the local construction waste and fine sandstone solid waste in Pujiang are sieved through a jaw crusher, a pulverizer, and a drum sieve The powder with the particle size of the mixture below 0.5mm is piled up. After weighing and proportioning in the hopper, 10% of lime is mixed with 60% of crushed construction waste and fine sandstone crystal solid waste, and then 20% of Pujiang crystal glass solid waste is synthesized and quantitatively transported to the double-horizontal mixer, and 10% is added. The water enters into the digestion bin after being forced to stir with the conveyor belt, and the lifting belt is sent into the digestion bin. After several substances are digested and reacted for 4-5 hours, they are released from the digestion bin, and the vertical strong powder machine is used to carry out deep crushing t...

[0025] A method for manufacturing autoclaved lime-sand bricks by using construction waste and crystal glass solid waste, the method includes the following steps: the local construction waste and fine sandstone solid waste in Pujiang are sieved through a jaw crusher, a pulverizer, and a drum sieve The powder with the particle size of the mixture below 0.5mm is piled up. After weighing and proportioning in the hopper, 15% of calcium carbide slag waste mixed with 65% of crushed construction waste and fine sandstone crystal solid waste is mixed with 10% of Pujiang crystal glass solid waste to be synthesized and quantitatively transported to the double-horizon mixer, and mixed into 10% water, after being forced to stir, use the conveyor belt to lift the belt and send it into the digestion bin. After 4-5 hours of digestion and reaction, several substances are released from the digestion bin, and the vertical strong powder machine is used for deep crushing to the rolling machine. The...

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...
