Method for continuously preparing activated clay

一种活性白土连续化制备方法

Abstract

The invention discloses a method for continuously preparing activated clay. The method comprises the following steps of: (1) metering bentonite, and adding the bentonite into a slurrying system to prepare original slurry; (2) conveying the original slurry to an activation system to prepare activated slurry; (3) conveying the activated slurry to an acid distribution system, performing filter pressing and deacidification, and then dispersing the activated slurry; (4) conveying the dispersed slurry to a rinsing system through a pipeline; (5) conveying slurry which is rinsed for three times to a filter pressing system through a pipeline, and conveying a filter cake which is obtained by filter pressing to a drying system through a conveying belt; (6) drying activated clay in the drying system; and (7) conveying the dried activated clay to a milling system through a pipeline, milling the activated clay through a Raymond mill, and then collecting the milled activated clay through a cyclone separator. According to the method, the environment pollution is reduced to a great extent in a continuous and mechanical manner. The flowing dust pollution and the emission of waste acid and boiling water are eliminated almost. The method is an industrial production method capable of realizing the recycling economy.
一种活性白土连续化制备方法,采用如下步骤:1)膨润土经计量后加入制浆系统制成原浆料;2)将原浆料输送至活化系统制成活化浆料;3)将活化浆料输送至分酸系统进行压滤脱酸,再打散;4)用管道输送打散浆料至漂洗系统;5)经过3次漂洗的料浆通过管道输送至压滤系统,压滤后的滤饼经传送带输送至烘干系统;6)在烘干系统中烘干活性白土;7)烘干活性白土通过管道输送至磨粉系统,经雷蒙机磨粉,然后通过旋风分离器收集。本发明的制备方法,利用连续化机械化,极大程度的降低对环境污染。扬尘污染及废酸沸水排放几乎没有,是一种循环经济的工业生产方法。
