摘要： A testing device, a testing method, and a design method for a rotary pressure filter. The device includes 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 includes adding a certain calculated amount of testing slurry into the filter frame, introducing a gas with a certain pressure into the stabilizer tank, filling the filter frame through the buffer tank, opening a valve at bottom of the filter frame, measuring a mass of the expelled filtrate expelled from the filter frame, measuring time of the filtering process, sampling and analyzing the filter cake and the expelled filtrate according to actual needs; and perform cleaning and drying processes sequentially.
