Embodiment Construction

[0029] figure 1 A dewatering plant in the form of a press 1 is shown seen from the side and in section for dewatering a liquid suspension of solid biological material, eg cellulose pulp. The press 1 has a first dewatering drum 2 and a second dewatering drum 4 . like figure 1 As shown by the arrow R in , the dehydration drum 2 is arranged to rotate counterclockwise. The dewatering drum 4 is arranged to rotate in the opposite direction, that is, clockwise, but, hereinafter, even if the second dewatering drum 4 is mirror-symmetrical with respect to the first dewatering drum 2, the dewatering drum 4 is also similar in structure and function to the dewatering drum 2, so it will not The dewatering drum 4 is described again in more detail.

[0030] The press 1 also comprises pressing means in the form of a barrel 6 inside which the first dewatering drum 2 is arranged to rotate. The barrel 6 has an inlet 8 on one side of it for a liquid suspension of cellulose pulp, ie a dry solid...

Abstract

A sealing arrangement (36) for a press (1 ) comprises a first sealing ring (54), in which a replaceable first sealing strip (76) is fixed, said first sealing strip (76) being arranged to slide towards the dewatering drum (2) while it rotates, and a second sealing ring (54) arranged at an axial distance from the first sealing ring (52), in which second sealing ring (54) a replaceable second sealing strip (92) is fixed, said second sealing strip being arranged to slide against the dewatering drum (2) while it rotates.Both the first and the second sealing rings (52, 54) are fixed in a common holding device (58) that is located at the first sealing ring (52). The second sealing ring (54) is fixed in the holding device (58) by means of at least one spacer element (102). At least a part (60, 62) of the first sealing ring (52) is detachable from the holding device (58) for being made to slide along said at least one spacer element (102) in order to allow replacing the first sealing strip (76).

Description

technical field [0001] The invention relates to a sealing arrangement for a press for dewatering a liquid suspension of solid biological material, said press comprising a rotary dewatering drum provided with a liquid-permeable layer and a pressing device arranged to The liquid is pressed into the dewatering drum in such a way that the liquid suspension is pressed against the liquid permeable layer, wherein the sealing means seals the pressing means against the dewatering drum. Background technique [0002] A press comprising dewatering drums is often used when dewatering a liquid suspension of solid biological material, for example a suspension of cellulosic fibers used in the production of pulp. Typically, the dewatering drum has on its outside a screen or screen against which the pulp is compressed in the gap formed between the barrel contained in the press and the dewatering drum. The liquid squeezed from the suspension passes through a screen or sieve plate into the dru...
