Manufacturing technology for baking-free brick with blind holes

一种带有盲孔的免烧砖制作工艺

Abstract

The invention discloses a manufacturing technology for a baking-free brick with blind holes. The manufacturing technology comprises the following steps: (1) burdening: mixing and uniformly stirring coal ash, ardealite, quartz sand, cement and water; (2) making brick: conveying the uniformly stirred raw materials to a brick-making machine, wherein blind hole models which are made of steel are arranged in the brick-making machine, and making brick blanks through high-pressure vibration and extrusion forming; (3) maintaining: firstly stacking the brick blanks in a 40 DEG C constant-temperature shed for 25-30 h, drawing out the blank hole models, transferring the brick blanks to be stocked in the open air, in the first three days after stacking the brick blanks in the open air, uniformly spraying water for 2 times a day, and placing the brick blanks for 15-25 days to prepare the bricks. The manufacturing technology overcomes the defect of the prior art. The technical design is reasonable and simple. The baking-free brick is high in waste utilization ratio, high in brick strength, light in weight, short in production period, and free from emission of pollutants. The manufacturing technology is objectively required.
本发明公开了一种带有盲孔的免烧砖制作工艺,(1)配料将粉煤灰、磷石膏、石英砂、水泥和水进行混合并搅拌均匀;(2)制砖将搅拌均匀后的原料输送至制砖机内,制砖机内设有盲孔模型,盲孔模型为钢铁制成,通过高压振动、挤压成型制成坯砖;(3)保养先将坯砖在40℃恒温棚中堆码放置25~30小时,后将盲孔模型抽出,再将坯砖移至露天堆码,移到露天堆码后前3天每天均匀喷水2次,放置15~25天后制成。本发明克服了现有技术的不足,工艺设计合理简单,是一种废弃物利用率高、砖体强度高、重量轻、生产周期短且无污染物排放的免烧砖及其生产工艺是客观需要的。
