It is not suitable for some research and prospecting operations. In addition, it has a complex structure, a large size, and is inconvenient to install and remove the filter cake. In order to overcome the above defects, I have developed a pressure-stabilized output filter press used for the research of filtrate recovery in prospecting operations. Utility Model Content
