<p>The present invention concerns a suction dryer, which comprises one or several filter plates (10). The filter plate (10) is fitted so that it can be displaced into contact with the material to be filtered. Negative pressure is applied into the filter plate so as to produce suction, so that the material to be filtered is arranged so as to adhere to the face of the filter plate, whereat the liquid to be filtered is sucked out of the material to be filtered. The suction dryer includes a distributor device (33) for the timing of the filtering stages, which said distributor device (33) comprises a rotor part (34) fitted stationarily on the structure, preferably a shaft (19), which displaces the filter plate (10) into the material to be filtered, and a stator part (35), which is functionally coupled to the rotor part and which can be set for the purpose of adjusting the filtering stages. The negative pressure applied to the filter plates is arranged so that it is transmitted through the ducts in the stator part (35) and through the ducts in the rotor part (34) at the time when the opening (40a, 42a) in the stator part (35) is located facing the mobile, preferably revolving, opening (34a, 34b...) in the rotor part (34).</p> |
