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.
