一、前言目前,冶金化工的过滤设备,一直采用以布为过滤介体的所谓板框压滤机、园盘、莫尔过滤机等,大多数是三十年代的老产品,设备陈旧落后,全凭手工操作,过滤速度慢,劳动强度大,耗布量多,已经阻碍了冶金工艺的自动化和影响冶金、化工工业的发展。金属过滤器的问世,为提高过滤速度和为过滤自动化创造了有利的条件。 I. Introduction At present, the metallurgical and chemical filtration equipment has been using the so-called frame filter press fabric filter, garden plate, Moore filter, etc., most of the old products of the thirties, outdated equipment, By manual operation, the filtering speed is slow, the labor intensity is big, the quantity of consumption is much, which has hindered the automation of metallurgical process and affected the development of metallurgy and chemical industry. The advent of metal filters has created favorable conditions for increased filtration speed and for filtration automation.
