The embodiment of the invention discloses a filter press. The filter press comprises a shell, a filter ring, a squeezing capsule, a filter pressing executing mechanism and a squeezing executing mechanism, wherein the filter ring is arranged in the shell; filtrate channels are formed between the filter ring and the shell; the squeezing capsule is arranged in the shell and is surrounded by the filter ring; driven by the squeezing executing mechanism, the part, in the shell, of the squeezing capsule can expand or shrink; filtration areas are formed between the squeezing capsule and the filter ring; the shell is provided with a filtrate outlet communicated with one filtrate channel, a filter cake outlet communicated with the filtration areas and a slurry inlet communicated with the filter pressing executing mechanism and one filtration area; and a separating mechanism for separating the filtration areas from the outside is arranged at the filter cake outlet. The filter press not only can obtain ideal filter cakes from the slurry with high concentration and big grain size but also has high recovery rate toward some slurry with low concentration, small grain size and certain value, so that the equipment provided by the invention solves the problems in the prior art.
