Production method for preparing elevator balancing weight from solid waste
The invention discloses a production method for preparing an elevator balancing weight from solid waste. The production method comprises the following steps: the solid waste is crushed into particleswith the particle size within 1.5 cm through a crusher; heavy particles with the density of 1.2 g/cm<3>-2.0 g/cm<3> are separated out from the particles through a gravity separator; the heavy particles enter a harmful substance detection machine in batches to be detected, the batches, where harmful substances exist, of the heavy particles are separated from the system, and the batches, where no harmful substances exist, of the heavy particles serve as balancing weight raw materials to be conveyed to the next step to be treated; the components of the heavy particles, the iron powder, the sandstone and the cement are proportioned according to the requirements of balancing weight, a proper amount of water is added, and the raw materials are stirred through a stirrer to uniformly mix all the component materials; and the uniformly stirred raw materials are poured into a prefabricated mold, vibrating and compacting by using a vibrating bar are conducted, and solidifying and molding are carried out. Waste is turned into wealth by recycling solid waste, and meanwhile, the prepared balancing weight material is uniform in density and convenient to fill and use, and does not damage a prefabricated mold.
本发明公开了一种利用固体废料制备电梯配重块的生产方法，包括以下步骤：通过破碎机将固体废料破碎成粒径在1.5cm以内的颗粒；通过重力分选机将颗粒分选出密度为1.2g/cm～2.0g/cm的重质颗粒；将重质颗粒分批次进入有害物质检测机进行检测，将重质颗粒存在有害物质的批次从系统中分离出来，将重质颗粒不存在有害物质的批次作为配重原料送至进行下一步处理；根据配重的要求，对重质颗粒、铁粉、砂石和水泥的组份进行配比，加入适量水并通过搅拌机对原料进行搅拌，使各种组份材料均匀混合；将搅拌均匀的原料倒入预制模具，并使用振动棒振动密实，凝固成型。本发明通过回收利用固体废料实现变废为宝，同时制成的配重材料密度均匀，装填使用方便，且不损坏预制模具。
