Abstract
Filter is the use of porous filter medium, retain the mixture of liquid and solid particles, solid particles, and to achieve solid, liquid separation equipment. Filter is widely used in chemical, petroleum, pharmaceutical, light industry, food, mineral processing, coal and water treatment sectors. Currently, hundreds of our existing large filter manufacturers. To meet the requirements of the industry and the market has been the emergence of various different models and methods of filter .Be driven by different methods of filtration, divided into gravity filters, vacuum filters and pressure filter categories. Pressed mode frame filter press with manual compression, mechanical compression and hydraulic clamping three forms. Is developing a new type of filtration equipment: mechanical press filtration equipment; to achieve residue-free layer of filtering a dynamic filter; Coal washing waste water treatment, chemical and oil industry equipment used in large filtration. The design of the filter frame for the hand over machine. It has the advantage of simple structure, easy to filter area and small size, operating pressure is high, the application of the ability of various materials, mainly small-batch production and small business applications

绪论
20世纪初,转鼓真空过滤机实现了操作上的连续过滤。自那时以来,各种类型的压滤机出现。间歇运行的压滤机因能实现自动化操作而得到发展,随着生产能力的进一步发展,过滤面积越来越大。压滤机应该基于泥浆的浓度,固体颗粒大小,液体粘度和选择压滤机的质量要求。使用过滤漏斗实验,测定不同过滤介质和过滤速度不同压差下,滤液固体颗粒含量,滤饼层的厚度和含水量,找出适当的过滤条件,初步选定的压滤机类型。然后根据定处理量选定过滤面积的容量,和实际测试。正在开发一种新型的过滤设备有:机械力压滤过滤设备;实现无动态过滤滤饼层;洗煤废水处理、化工和石油等行业大型使用过滤设备。在过滤理论研究,残留在滤室内的滤饼其过滤阻力的计算和孔隙度、过滤速度、过滤设备模拟和放大,液体澄清过滤和动态过滤机制,以及过滤介质,是重要的课题。
