Problems solved by technology

[0003] At present, basalt is used as a chemical raw material, and its main components are silicon dioxide, aluminum oxide, iron oxide, calcium oxide, magnesium oxide, etc., among which the content of silicon dioxide is the largest, and the solid waste produced by basalt after chemical production is usually processed. Landfill, reduce the utilization rate of basalt solid waste, and at the same time cause certain pollution to the environment

Abstract

The invention relates to the technical field of preparation of light sintered bricks, in particular to a method for preparing a light sintered brick from basalt solid waste. The method comprises the steps of: weighing the raw materials according to a certain proportion; putting the raw materials into a pug mill together for stirring and pugging; uniformly mixing the raw materials to form pug; molding the pug through a plastic extruding machine; preparing a green brick with a certain specification; putting the green brick into a drying furnace for drying to form a dried green brick; sending thedried brick blank into a kiln for sintering; keeping the temperature in the kiln for a certain time, and then performing cooling to obtain the light sintered brick. Basalt solid waste is used as a main raw material for preparation; the proportion of the basalt solid waste is more than 70%; heavy metal in basalt solid waste is solidified through high-temperature sintering, resource and harmless utilization of the waste is achieved, natural mineral resources are saved, environmental protection and improvement are facilitated, and the prepared light sintered brick belongs to an inorganic heat preservation material and has the advantages of being light, high in strength, resistant to corrosion, free of aging and the like.

Description

technical field [0001] The invention relates to the technical field of preparation of light-weight sintered bricks, in particular to a method for preparing light-weight sintered bricks by using basalt solid waste. Background technique [0002] The bricks used for masonry load-bearing and non-load-bearing walls made of clay, shale, coal gangue or fly ash after molding and high-temperature roasting are collectively called sintered bricks. According to different raw materials, it can be divided into sintered clay bricks, sintered fly ash bricks, sintered shale bricks, etc. Sintered ordinary bricks are called sintered ordinary bricks for solid or sintered bricks with a porosity of less than 25%. The production and use of ordinary clay bricks have a history of more than 3,000 years in my country. Nowadays, among the wall materials used in construction projects, ordinary clay bricks still dominate. Although ordinary clay bricks have many shortcomings, due to reasons such as low...
