<p>Pressure strainer device for cellulose, paper or equivalent pulp suspension comprising at least one straining cylinder, through which the acceptable pulp is strained and in connection with which there is provided at least one vane revolving about its axis and moving at a small distance from it and which vane cleans the face of the straining cylinder facing the pulp to be strained and which vane has for the purpose of collecting the rejected pulp a cavity extending from one end to the other and opening through a slot towards the straining cylinder and communicating at one end with the reject space. The reject space is separated from the entry space of the pulp to be strained by a secondary straining cylinder, through which the acceptable pulp still travelling along with the rejected pulp is strained and in connection with which there is provided at least one secondary vane revolving about its axis and moving at a small distance from it, which secondary vane cleans the face of the secondary straining cylinder facing the reject space.</p> |
