Method for making bricks by utilizing spent bleaching clay
The invention discloses a method for making bricks by using spent bleaching clay. The method comprises the following steps: (1) adding solvent oil into spent bleaching clay, uniformly stirring and mixing, filtering to obtain a first-stage filter cake and first-stage solvent oil containing lubricating oil base oil, adding the solvent oil into the filter cake, repeating the above steps for three times, and finally respectively collecting a fourth-stage filter cake and fourth-stage solvent oil containing lubricating oil base oil; (2) evaporating the filter cake, settling and layering to obtain upper-layer solvent oil, and recovering the upper-layer solvent oil, wherein the lower layer is bleaching clay without a solvent; and (3) calcining the bleaching clay, adding the mixture and water, uniformly stirring to obtain a mixed material, standing, and carrying out compression molding to obtain the bricks. The bricks prepared by processing and utilizing the spent bleaching clay have high compressive strength and good water resistance; and environmental pollution is avoided due to reutilization of waste, and resources are saved.
本发明公开了一种利用废白土制砖的方法,包括以下步骤:(1)在废白土中添加溶剂油,然后搅拌混合均匀,然后过滤得到一级滤饼和一级含有润滑油基础油的溶剂油;再向滤饼中添加溶剂油,重复上述步骤3次,最后分别收集四级滤饼和四级含有润滑油基础油的溶剂油;(2)将滤饼进行蒸脱,沉降分层得到的上层溶剂油回收,下层为不含溶剂的白土;(3)将白土煅烧,然后加入混料和水搅拌均匀得到混合物料,放置,压制成型得到所述的砖。本发明中通过将废白土加工利用制得的砖具有的抗压轻度高、耐水性好;废物的重新利用避免了环境的污染,节省了资源。
