Method for preparing light sintered brick from basalt solid waste
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.
本发明涉及轻质烧结砖制备技术领域，具体为一种利用玄武岩固废制备轻质烧结砖的方法，按一定配比称取原料，将原料共同装入练泥机中进行搅拌练泥，使得原料混合均匀形成泥料，将泥料通过挤塑机成型，并制成一定规格的砖坯，将砖坯放入烘干炉内烘干形成烘干砖坯，将烘干砖坯送入窑炉内烧结，并在窑内保温一定时间后再冷却降温得到轻质烧结砖，利用玄武岩固废作为主原料进行制备，玄武岩固废的占比在70％以上，通过高温烧结，将玄武岩固废中的重金属进行了固化，不仅实现了废弃物资源化、无害化利用，而且节约天然矿产资源，利于环境的保护和改善，制备所得的轻质烧结砖属于无机保温材料，具有的轻质、高强、耐腐蚀、不老化等优点。
