摘要： The present invention relates to a rotary pressure filter testing apparatus, a testing method and a design method thereof. The apparatus comprises a stabilizer tank; a buffer tank connected to the stabilizer tank; a filter frame disposed beneath the buffer tank, and connected to the buffer tank; a liquid receiving tank disposed beneath the filter frame; an electronic balance disposed at bottom of the liquid receiving tank; and a seconds counter. The testing method is to add a certain amount of calculated testing tank into the filter frame, then introduce a gas with a certain pressure into the stabilizer tank, fill the filter frame through the buffer tank, then open a valve at bottom of the filter frame, measure a mass of discharged mother liquid in the filter frame, measure time of the filtering process, and sample and analyze the filtered filter cake and the mother liquid according to actual needs; subsequently, perform cleaning and drying processes sequentially according to such method. The present invention largely reduces the testing costs, and meanwhile, actual working conditions can be simulated more accurately, thereby obtaining accurate and reliable design data.

摘要： A device for reducing pressure fluctuation of a pressure filter frame and a pressure filter. The device includes a pressure filter frame that is a cylindrical housing. An inner wall of the pressure filter frame is further provided with a buffer plate. A plurality of openings are provided in the buffer plate. A gap is remained between the buffer plate and the inner wall of the pressure filter frame. A plurality of supporting posts are disposed in the gap, which fixedly connect the inner wall of the pressure filter frame with the buffer plate.
