Preparation method and device of phosphogypsum pretreatment agent
The invention belongs to the technical field of phosphogypsum pretreatment agent preparation, and particularly relates to a preparation method of a phosphogypsum pretreatment agent, which can reduce the consumption of quicklime in the phosphogypsum pretreatment process, thereby saving resources and energy consumption; meanwhile, a new resource utilization way can be provided for the old cement stone fine powder in the waste concrete, the additional value of the old cement stone fine powder is improved, the effect of treating waste with waste is achieved, and good economic benefits, environmental benefits and social benefits are achieved; according to the preparation device of the phosphogypsum pretreatment agent, the crushing mechanism and the grinding mechanism are driven by one motor to work at the same time, energy can be saved, concrete blocks are crushed twice through cooperative use of the crushing mechanism and the grinding mechanism, the concrete crushing treatment effect can be improved, and during grinding, the crushing efficiency is improved. The semi-circular plate can be driven to shake left and right in a reciprocating mode, screening holes of the semi-circular plate are prevented from being blocked, and crushing efficiency is improved.
本发明属于磷石膏预处理药剂制备技术领域，具体涉及通过本发明一种磷石膏预处理药剂的制备方法，不仅可以降低磷石膏预处理过程中的生石灰消耗量，从而节约资源和能耗，同时可以为废弃混凝土中的老旧水泥石细粉提供新的资源化利用途径并提高其附加值，达到以废治废的效果，具有良好的经济效益、环境效益和社会效益；本发明一种磷石膏预处理药剂的制备装置通过一个电机带动破碎机构以及碾碎机构同时工作，可节约能源，并且通过破碎机构以及碾碎机构的配合使用，对混凝土块进行两次破碎，可以提高对混凝土破碎处理的效果，在进行碾压时，可以带动半圆形板左右往复抖动，防止半圆形板的筛孔堵塞，提高破碎效率。
