Preparation method of environment-friendly coal gangue-based hollow brick
The invention discloses an environment-friendly coal gangue-based hollow brick preparation method, which comprises: uniformly stirring and mixing a fuel, a filler and a curing material, sequentially adding a binder and water, and uniformly stirring and mixing to obtain a mixture; feeding the mixture into an extruder for extrusion molding, and cutting by a cutting machine to obtain a green brick; curing the green brick in a high-temperature and high-humidity environment for 10-15 hours, and then placing the green brick in a shade place at normal temperature for 3-5 days to obtain a cured greenbrick; sending the cured brick blank into a kiln for firing to obtain the hollow brick; the defects in the prior art are overcome, construction waste and foundry sand waste are effectively utilized, the manufactured hollow brick is high in compressive strength, kiln tail gas pollution is small in the production process, and the environment-friendly effect is good.
本发明公开了一种环保型煤矸石基空心砖制备方法，包括以下步骤：将燃料、填充料、固化料搅拌混合均匀，然后依次加入粘结料和水，再次搅拌混合均匀，得到混合料；将混合料送入挤出机中挤出成型，经切割机切割后得到砖坯；将砖坯在高温高湿环境中固化10‑15小时，然后在庇荫处常温放置3‑5天，得到固化砖坯；将固化砖坯送入炉窑内烧制，得到空心砖，本发明克服了现有技术的不足，有效的利用了建筑垃圾和铸造砂废料，制造的空心砖抗压强度大，生产过程中炉窑尾气污染小，环保效果好。
