一、概况过滤在化工生产中是普遍应用的化工过程之一,用于固、液两相分离。由于分离的推动力不同,分为吸滤,加压过滤和离心分离三类。而目前生产中,对于粘性较大难过滤的物料,必须加压过滤,即需较大的推动才能过滤。在加压过滤设备中,到现在极大部分仍沿用板框压滤机,这种老式板框压滤机在板框的压紧、拉开,卸料和洗刷滤布方面都是采用落后的手工操作,不仅操作工人的劳动强度大,生产条件恶劣,而且劳动生产率很低,严重地影响我国染化、制药等化工行业的生产大幅度发展。为了填补我 First, the overview Filtration in chemical production is one of the chemical processes commonly used in solid and liquid two-phase separation. As the driving force for separation is divided into suction filter, pressure filtration and centrifugal separation of three categories. At present, the production of viscous more difficult to filter the material must be pressure filtration, which requires a larger impetus to filter. In the pressurized filtration equipment, to the great part still use the frame filter press, this old frame filter press in the frame of the compaction, opened, unloading and washing cloth are used behind By manual operation, not only is the labor intensity of the operating workers high and the production conditions are harsh, but the labor productivity is very low, which has seriously affected the substantial development of the chemical industry such as dyeing, pharmacy and other industries in our country.
