The invention refers to a device for dewatering and washing of fibrous mass. According to the invention, the device is comprised in part of a housing (1), which contains a revolving drum (2) in the shape of a hollow cylinder with a side wall equipped with holes (3) with feed tracks through (11) and shovels arranged in these (12), in part a device (30) for supplying washing fluid and partly a device (14) set up in the drum (2) which is designed to cause the shovels (12) to move themselves back and forth in the feed tracks (11). The device is characterized by the fact that the device (14) is constructed of a number of shovels (12) guidable with a carrier (15) and an axle (16), whose centre line (17) is located off-centre in relation to the drum's (2) centre line (18). The carriers (15) are connected with the axle (16) so that they can turn around the centre line (17) of the axle. Between the inside of the housing (1) and the drum (2) there is a cavity (4) for passage of the fibrous mass, which narrows in the direction from the housing's (1) inlet hole (5) to its outlet hole (6).<IMAGE> |
