FIELD: instrument engineering.
SUBSTANCE: invention relates to equipment for separation of solid substances from fiber-containing slurries or fibers from suspension of fibrous material. Vertical press comprises cylindrical sieve, in which press screw is arranged to drive by means of drive. In press there is a receiver for suspension, drain for filtrate and outlet hole for dehydrated solid material. Cylindrical sieve is surrounded by a tank of back pressure of filtrate and in axial direction consists of several parts. At least the lowest part forms a back pressure tank having a larger diameter. Said tank with increased diameter can shift along vertical in axial direction. Receiver for suspension is located on upper end of press, and outlet hole for dehydrated solid material – at its lower end. Filtrate drain is arranged at the lower end of the back pressure tank of the filtrate.
EFFECT: as a result, higher capacity and efficiency of dehydration, as well as easier cleaning of press during its clogging.
