Description
技术领域 technical field
本发明涉及一种建筑垃圾抛重破碎装置及其方法。 The invention relates to a construction waste throwing weight crushing device and a method thereof.
背景技术 Background technique
随着现代城市化的进程，我国的建筑垃圾逐年递增，大众提倡变废为宝，节约资源，绿色生活的理念，建筑垃圾分选机行业迫切需要一种小型综合垃圾分选机，可以分布城市各点角落，进行垃圾的分选与回收，避免垃圾的填埋与焚烧的传统任务。 With the process of modern urbanization, my country's construction waste is increasing year by year. The public advocates the concept of turning waste into treasure, saving resources, and living a green life. The construction waste sorting machine industry urgently needs a small comprehensive waste sorting machine that can be distributed in cities. Sorting and recycling of garbage at various points and corners, avoiding the traditional tasks of landfill and incineration of garbage.
建筑垃圾主要包括混凝土、废砖瓦、墙灰、金属物和木材物等物料，现有建筑垃圾分选是将物料经过抛重后用专门的破碎机进行破碎或者是先采用破碎机破碎物料后再进行抛重分选。徐州天地重型机械制造有限公司发明专利文献申请公布号CN102861718A，是一种建筑垃圾比重分选装置，上述专利是利用抛重的方法进行对骨料的轻重质之分，处理后的料无区分有无磁选且物料为粗质骨料，无进行细料处理，最终的粗质物料需要区别出有无磁性材料与破碎后才能进行后续的回收利用。它所采用料仓进料方式由于高达2m高度的限制，只能使用机具进料，在处理建筑垃圾的时候进料的效率慢，影响作业的时间。最后该专利分选出的物料并无破碎，出现的是粗质骨料，需要进行专门破碎分选机进行细料破碎，其需要另外增加破碎机破碎的成本。 Construction waste mainly includes materials such as concrete, waste bricks and tiles, wall ash, metal objects, and wood objects. The existing construction waste sorting is to use a special crusher to crush the materials after throwing weight, or use a crusher to crush the materials first. Carry out weight sorting again. Xuzhou Tiandi Heavy Machinery Manufacturing Co., Ltd. Invention Patent Literature Application Publication No. CN102861718A is a construction waste specific gravity sorting device. The above patent uses the method of throwing weight to classify the light and heavy aggregates, and the processed materials have no distinction. There is no magnetic separation and the material is coarse aggregate without fine material treatment. The final coarse material needs to be separated from magnetic material and crushed before subsequent recycling. Due to the limitation of the height of up to 2m, the feeding method of the silo can only be fed by machines and tools. When processing construction waste, the feeding efficiency is slow, which affects the operation time. Finally, the material sorted out by this patent is not broken, but coarse aggregate, which needs to be crushed by a special crushing and sorting machine, which needs to increase the cost of crushing by the crusher.
