厢式(板框式)压滤机是一种间歇操作的加压过滤设备，广泛应用于石油、化工、石材、陶瓷、矿业、冶金、洗煤、造纸、染料、食品和环保等行业各类悬浮液的固液两相分离及工业废水污泥的脱水处理。本机通过压紧机构将滤板压紧，用输浆泵将悬浮液输入各滤板形成的滤室，在泵压力的作用下，以滤布作为过滤介质来达到固液分离的目的。本机有手动、机械、液压等多种传动方式，滤板有聚丙烯、超高分子聚乙烯、橡胶、橡胶隔膜板等多种材质形式可供选择。
Van (Frame type) filter press is a kind of pressure and filtration equipment with intermittent operation . It is widely used to separate all kinds of suspension of the solid-liquid and de-water for industrial wast water in petroleum, chemical, stone, ceramics, mining, metallurgy, coal washing, paper, dyes, food and environmental protection industries. the compaction plate is pressed by the parts of press , the suspension is inputed to filter chambers made of all plates with the input pump . Under pressure of pump, solid-liquid separation purposes achieves with filter cloth as a filter media. The machines has following type , manual, mechanical, hydraulic and other transmission. The plate can be selected as variety of materials , such as polypropylene, ultra-high molecular polyethylene, rubber, rubber diaphragm plate
