板框压滤机滤饼水分的清除方法。板框压滤机的滤饼水分一般包括物理一机械水、物理一化学水以及化学水。采用机械的方法可脱去类水分，但很难脱除第二类水分，而强化干燥则可以脱去、二类水分，热力干燥可以脱去第三类水分。所谓空气干燥法，就是使用压缩空气对压滤机滤饼进行吹干的一种强化脱水方法，它可以脱去一部分物理一化学水，这是介于机械脱水和热力干燥之间的一种脱水方法。
在板框压滤机的滤饼除水中常用的是空气干燥法，空气干燥法不仅能显着降低压滤机的滤饼水分，提高压滤机的处理量，而且操作简便，容易实现。这种脱水方法的推广应用，将有助于提高我国选煤厂压滤机的工作效果，真正实现煤泥厂内回收、洗水闭路循环。
采用大流量给料泵或压缩空气给料罐快速充满压滤机滤室，待成饼以后即停止给料，然后向压滤机滤室通入一定时间的压缩空气，对滤饼进行吹干。这些是空气干燥法的关键，因此这些步骤马虎不得。
The method for removing moisture from the filter cake of the plate and frame filter press. The filter cake moisture of the plate and frame filter press generally includes physical-mechanical water, physical-chemical water, and chemical water. The first type of water can be removed by mechanical means, but it is difficult to remove the second type of water, while the intensive drying can remove the first and second types of moisture, and the thermal drying can remove the third type of water. The so-called air drying method is an intensive dehydration method for drying the filter cake of compressed filter by using compressed air, which can remove a part of physical-chemical water, which is a kind of dehydration between mechanical dehydration and thermal drying. method.
In the filter cake of the plate and frame filter press, the air drying method is generally used. The air drying method can not only significantly reduce the moisture of the filter cake of the filter press, but also improve the processing capacity of the filter press, and the operation is simple and easy to implement. The popularization and application of this dehydration method will help to improve the working effect of the filter press in China's coal preparation plant, and truly realize the closed loop of recycling and washing in the slime plant.
The large-flow feed pump or compressed air feed tank is used to quickly fill the filter press filter chamber, and the feed is stopped after the cake is formed, and then the compressed air is supplied to the filter press filter chamber for a certain period of time to dry the filter cake. . These are the key to air drying, so these steps are sloppy.
