板框压滤机的设计（全套图纸）.doc

摘要 过滤机是利用多孔性过滤介质，截留液体与固体颗粒混合物中的固体颗粒，而实现固、液分离的设备。过滤机广泛应用于化工、石油、制药、轻工、食品、选矿、煤炭和水处理等部门。目前，国现有几百家大型生产厂家按获得过滤推动力的方法不同，分为重力过滤器、真空过滤机和加压过滤机三类。板框压滤机有手动压紧、机械压紧和液压压紧种形式。正在发展的新型过滤设备有：机械力压榨过滤设备；能实现无滤渣层过滤的动态过滤机；洗选煤炭污水处理、化工和石油工业用的大型过滤设备。的优点是结构简单、制造容易、过滤面积大而占地面积小、操作压力高、对各种物料的适用能力强，主要应用与小型企业小批量生产过滤机过滤面积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 Key Words:Filter Filter area Plates Filter box Screw 目录 绪论 6 1 板框压滤机 7 1.1 板框压滤机的起源及发展 7 1.1.1 板框压滤机的起源 7 1.1.2 板框压滤机的发展 7 1.1.3 板框压滤机的发展趋向 8 1.2 板框压滤机的简介及分类 8 1.3 板框压滤机的结构 8 1.4 板框压滤机的工作原理 9 2. 板框压滤机的设计 9 2.1 板框压滤机的过滤原理及特点 9 2.1.1 板框压滤机的结构 9 2.1.2 板框压滤机的流程 10 2.1.3 滤布的选型 12 2.2 过滤机的参数 12 2.3 滤板和滤框的设计以及强度计算 13 2.3.1 板框和滤板材料选择 13 2.3.2 滤板的强度计算 15 2.3.3 滤框的强
