板框壓濾機濾餅水分的清除方法。板框壓濾機的濾餅水分一般包括物理一機械水、物理一化學水以及化學水。采用機械的方法可脫去類水分，但很難脫除第二類水分，而強化干燥則可以脫去、二類水分，熱力干燥可以脫去第三類水分。所謂空氣干燥法，就是使用壓縮空氣對壓濾機濾餅進行吹干的一種強化脫水方法，它可以脫去一部分物理一化學水，這是介于機械脫水和熱力干燥之間的一種脫水方法。
在板框壓濾機的濾餅除水中常用的是空氣干燥法，空氣干燥法不僅能顯著降低壓濾機的濾餅水分，提高壓濾機的處理量，而且操作簡便，容易實現(xiàn)。這種脫水方法的推廣應用，將有助于提高我國選煤廠壓濾機的工作效果，真正實現(xiàn)煤泥廠內(nèi)回收、洗水閉路循環(huán)。
采用大流量給料泵或壓縮空氣給料罐快速充滿壓濾機濾室，待成餅以后即停止給料，然后向壓濾機濾室通入一定時間的壓縮空氣，對濾餅進行吹干。這些是空氣干燥法的關(guān)鍵，因此這些步驟馬虎不得。
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.
