Abstract:
The invention concerns a filtration module (1) comprising an end plate (3) run through with apertures (4) wherein are engaged end parts of the filtering elements (5). Sealing means (7, 8) are engaged on the end parts projecting from the filtering elements (5) and compressed between the end plate (3) and a clamping plate (9). The sealing means (7, 8) comprise at least a first sealing plate (7) made of elastomer material having a hardness less than 60 Shore A and a second sealing plate (8) superposed on the first sealing plate (7) made of an elastomer material having a hardness greater than the hardness of the first elastomer material of the first sealing plate (7). The second sealing plate (8) comprises apertures (11a) in the axial alignment of the filtering elements (5) and cavities (11b) surrounding the apertures (11a) on the inside of the second sealing plate (8) for receiving the filtering elements (5) ends which are urged to rest on supporting ledge (17) of the second sealing plate (8).
Abstract:
A pressurized screen arrangement for screening lignocellulose-containing fiber material, comprising a screen housing (10) with a screen cage (11) and a rotor. Both ends of the screen cage (11) are arranged in first and, respectively, second attachment members (17, 18) in the screen housing (10). Both ends of the screen cage (11) are fitted into the attachment members (17, 18) with radial clearance, and an axial support (21) is provided at least at one of the attachment members (17, 18).
Abstract:
A filtration array comprising a main raw fluid supply line and a main filtered fluid collecting line, at least one filtration flow path extending between the main raw fluid supply line and the main filtered fluid collecting line; each of the at least one filtration flow path is configured with a filtering assembly comprising a pair of filter units coaxially extending from a common manifold configured on the filtration flow path and is in flow communication with the main raw fluid supply line and the main filtered fluid collecting line, each of the filter units comprising a plurality of parallely disposed filter members.
