Description
技术领域technical field
本发明属于工程材料热加工的技术领域,涉及金属材料铸造工艺设备,更具体地说,本发明涉及一种铸造旧砂、炉渣回收处理设备。The invention belongs to the technical field of thermal processing of engineering materials, and relates to metal material casting process equipment. More specifically, the invention relates to a recycling and processing equipment for casting old sand and slag.
背景技术Background technique
目前,铸造产业得到迅速发展,相关的资源如造型砂等,越来越紧张或短缺;人类环境保护意识已普遍提高,而铸造行业旧砂或炉渣处理的工作环境存在严重的粉尘污染。At present, the foundry industry is developing rapidly, and related resources such as molding sand are becoming more and more tense or in short supply; human awareness of environmental protection has generally increased, and the working environment of used sand or slag treatment in the foundry industry has serious dust pollution.
目前铸造行业中废旧砂的处理存在的主要问题是:At present, the main problems in the treatment of waste sand in the foundry industry are:
相当一部分铸造企业产生的旧砂、炉渣只做了人工简单的分选。炉渣中渣铁含量一般达5%~20%左右,形状、大小不等,炉渣中参杂硫化物、渣铁等,外形不规则多布满荆棘、毛刺,人工只能清选大块的或渣体表面的细小块,无法彻底清选。人工清选后炉渣中仍有3%~近20%(少数甚至超过20%)的渣铁流失填埋;而旧砂虽然经过人工清选也仍有2%到近10%的渣铁流失,直接导致资源流失浪费。人工处理粉尘大,环境污染严重。人工日清选效益不高,日处理量在2吨左右。而且这样得到的再生砂,灰分没有得到有效地处理,其质量难以保证。A considerable part of the old sand and slag produced by foundry enterprises are only manually sorted. The slag iron content in the slag is generally about 5% to 20%, and the shape and size are different. The slag is mixed with sulfide, slag iron, etc., and the shape is irregular and full of thorns and burrs. Only large pieces or burrs can be cleaned manually. Small pieces on the surface of the slag body that cannot be cleaned thoroughly. After manual cleaning, there are still 3% to nearly 20% (a few or even more than 20%) of the slag and iron in the slag lost to landfill; and although the old sand has been manually cleaned, 2% to nearly 10% of the slag and iron are still lost. It directly leads to resource loss and waste. Manual processing has a lot of dust and serious environmental pollution. The efficiency of artificial daily cleaning is not high, and the daily processing capacity is about 2 tons. Moreover, the ash content of the regenerated sand obtained in this way has not been effectively treated, and its quality is difficult to guarantee.
部分企业为了减小资源浪费,采取了半自动化设备进行废旧砂、炉渣处理,虽然渣铁能够很好地回收,但工人劳动强度大,同时产生的粉尘却更大,导致环境污染加剧。In order to reduce the waste of resources, some enterprises adopt semi-automatic equipment to process waste sand and slag. Although slag and iron can be recovered well, the labor intensity of workers is high, and the dust generated at the same time is greater, which leads to aggravated environmental pollution.
经专利和技术文献检索,目前国内还没有相关的专用设备,既能实现渣铁、旧砂高效的分选,又能减小或降低粉尘污染物排放。According to the search of patents and technical literature, there is currently no relevant special equipment in China, which can not only realize the efficient separation of iron slag and old sand, but also reduce or reduce the emission of dust pollutants.
