奥斯普雷(Osp- rey)皮带压滤机是一 种连续过滤的设备, 最近由英国WillianJones公司研制成功。给料矿浆需在低剪切速度搅拌条件下添加絮凝剂,矿浆进入过滤机后,滤液从皮带或两边可调溢流堰排除,絮凝矿粒沉淀在皮带上。过滤的物料被夹在两条聚酯皮带中,流入一组直径逐渐减小、弯曲度不断变化的对辊之间,滤饼中的水分逐渐受挤压而脱除。 过滤空间对滤饼产生两个力,一是因滤布在拉紧的情况下围绕着辊子转动而产生的 The Ospray belt filter press is a continuous filtration unit that was recently developed by Willian Jones UK. The feed slurry should be added flocculant under the conditions of low shear mixing speed. After the slurry enters the filter, the filtrate is removed from the belt or adjustable weirs on both sides, and the flocculated ore particles settle on the belt. Filtered material is sandwiched between two polyester belts, flowing into a group of gradually decreasing diameter, bending changes between the roller, the filter cake of water gradually squeezed and removed. The filter space creates two forces on the filter cake, one due to the rotation of the filter cloth around the roller under tension
