Process for manufacturing bricks by recovering nonmetal powder of waste circuit boards
The invention is suitable for the technical field of waste circuit board recovery, and provides a process for manufacturing bricks by recovering nonmetal powder of waste circuit boards. Circuit boardfragments are obtained by successively crushing waste circuit boards; circuit board residues are obtained by further crushing the circuit board fragments; the circuit board residues are separated by wind power flotation to obtain nonmetal wastes and metal wastes; the nonmetal wastes are conveyed to a resin powder storage tower for storage; the nonmetal wastes are mixed with cement, stone sand andexcitants in a closed space by stirring to obtain mixtures; and the mixtures are pressed and processed to obtain baking-free bricks. By storing the nonmetal wastes in the storage tower and then mixingin the closed space, the generation of flying dust by inputting powder to a mixing area can be prevented to a greatest extent.
本发明适用于废旧线路板回收技术领域，提供了一种废旧线路板非金属粉回收制砖工艺，通过依次破碎废弃线路板，获得线路板碎料，进一步粉碎线路板碎料，获得线路板碎末，采用风力浮选，分离线路板碎末，获得非金属废料和金属废料，将非金属废料输送到树脂粉末存储塔进行存储，将非金属废料与水泥、石砂、激发剂在一个密闭空间内通过搅拌混合，获得混合料，将混合料压制加工，获得免烧砖，本发明通过存储塔存储非金属废料，然后在一个密封空间内搅拌混合，可以最大化杜绝粉末在输入搅拌区域时产生扬尘。
