Method for removing moisture in filter cake of plate and frame filter press

In industrial applications, plate and frame filter presses almost encounter various filtering objects, and it also means that plate and frame filter presses are used in various industries. However, in terms of use effects, plate and frame filter presses are not suitable for all There are good treatment measures for filtering objects. Especially for the removal of water in the filter cake, it is necessary to take corresponding high-efficiency measures to remove the water in the filter cake.

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 methods, but it is difficult to remove the second type of water, and enhanced drying can The first and second types of moisture can be removed, and the third type of moisture can be removed by thermal drying. The so-called air drying method is an enhanced dehydration method that uses compressed air to dry the filter cake of the filter press. Chemical water, which is a dehydration method between mechanical dehydration and thermal drying.

The air drying method is commonly used in the filter cake water removal of the plate and frame filter press. The air drying method can not only significantly reduce the filter cake moisture of the filter press, but also increase the processing capacity of the filter press, and it is also easy to operate and easy to achieve. The popularization and application of this dehydration method will help to improve the working effect of the filter press in my country's coal preparation plant, and truly realize the closed-circuit cycle of recovery and washing water in the coal slime plant.

Use a large-flow feed pump or a compressed air feed tank to quickly fill the filter chamber of the filter press, stop feeding after the cake is formed, and then introduce compressed air into the filter chamber of the filter press for a certain period of time to dry the filter cake .These are the keys to air drying, so these steps must not be sloppy.
