Preparation method of coal gangue hollow bricks
The invention provides a preparation method of coal gangue hollow bricks. The method comprises the following steps of 1, raw material selection, wherein a fuel, a filling material and a curing material are crushed, then a binding material and water are sequentially added, and stirring is performed again for uniform mixing to obtain crushed raw materials; 2, hollow brick forming, wherein the mixture is fed into an extruder for extrusion forming under the forming pressure of 2.2-2.4 MPa, and cutting is performed through a cutting machine to obtain green bricks; 3, green brick stacking, wherein the cut formed hollow bricks are stacked on trays; 4, drying, wherein the formed hollow bricks stacked on the trays are conveyed to a drying chamber for drying; 5, roasting, wherein the dried hollow bricks are conveyed to a roasting chamber for roasting; 6, cooling; and 7, warehousing. According to the preparation method of the coal gangue hollow bricks, the temperature of the drying chamber and the temperature of the roasting chamber can be adjusted and controlled by workers, energy conservation and emission reduction are achieved, and the prepared coal gangue hollow bricks are stable in structure.
本发明提供了一种煤矸石空心砖的制备方法，包括包括以下步骤：步骤一，选取原料，将燃料、填充料和固化料破碎，然后依次加入粘结料和水，再次搅拌混合均匀，得到破碎后的原料；步骤二，空心砖成型，将混合料送入挤出机中挤出成型，成型压力为2.2‑2.4MPa，并经切割机切割后得到砖坯；步骤三，码坯，将切割之后的成型空心砖进行码坯堆放于托盘上；步骤四，烘干，将码坯堆放在托盘上的成型空心砖送至烘干室进行烘干处理；步骤五，培烧，将烘干之后的空心砖送至培烧室进行培烧；步骤六，冷却；步骤七，入库，本发明所提供的一种煤矸石空心砖的制备方法，烘干室和焙烧室的温度皆可以通过工人调设控制，不仅节能减排，而且制备的煤矸石空心砖结构稳固。
