Patent ID: 7640853

Claim:
Press for separating solid and liquid parts of matter, comprising: a cage ( 2 ) presenting a cylindrical lateral wall ( 6 ) and two flanges ( 7 ) closing said cage respectively at one end and at the other end of said lateral wall ( 6 ); means ( 4 , 13 - 16 ) for mounting said cage ( 2 ) to rotate about its axis ( 3 ) in a position where the latter is positioned horizontally, comprising a chassis ( 4 , 14 , 16 ); means ( 21 - 24 ) for selectively controlling the rotation of said cage ( 2 ) about its axis ( 3 ); a deformable flexible membrane ( 8 ) positioned in said cage, fixed in a seal-tight manner to the lateral wall ( 6 ) of the cage along two opposite longitudinal edges ( 9 ) and fixed in a seal-tight manner to the flanges ( 7 ) along two respective transversal edges ( 10 ) each situated between an end of one longitudinal edge ( 9 ) and an end of the other longitudinal edge ( 9 ) so that said membrane ( 8 ) separates the internal volume of said cage ( 2 ) into a pressing chamber ( 11 ) delimited by said membrane ( 8 ), by a first half of said lateral wall ( 6 ) situated between said two opposite longitudinal edges ( 9 ) and by a first half of each of said flanges ( 7 ) situated, relative to the respective transversal edges ( 10 ), on the side of the first half of the lateral wall ( 6 ), and into a control chamber ( 12 ) delimited by said membrane ( 8 ), by the second half of said lateral wall ( 6 ) and by the second half of said flanges ( 7 ), said flexible membrane ( 8 ), at rest, having almost the form of half of the cage ( 2 ); means ( 13 , 17 ) for admitting a pressure agent into said control chamber ( 12 ) and means ( 13 , 18 ) for sucking said pressure agent out of said control chamber ( 12 ); at least one door ( 19 ) blocking or revealing an opening provided in said first half of the lateral wall ( 6 ) of the cage ( 2 ); drainage means ( 20 ) equipping said first half of the lateral wall ( 6 ) of the cage ( 2 ); and means for recovering said liquid part of the matter leaving the pressing chamber ( 11 ) via said drainage means ( 20 ); wherein said recovery means comprise: on the cage ( 2 ), at least one external racking device ( 33 ), and a connection unit ( 39 ) through which opens out an outlet orifice ( 37 ) of the racking device ( 33 ); and on said chassis ( 4 , 14 , 16 , 42 , 43 ), a liquid taking device ( 40 ) comprising a telescopic tubular unit ( 46 ) having a retracted position in which said telescopic unit ( 46 ) presents no obstacle to the rotation of the cage ( 2 ) and an extended position in which said telescopic unit ( 46 ) is adapted, when the cage ( 2 ) is in a predetermined pressing angular position, to come against said connection unit ( 39 ) in a seal-tight bearing manner around the outlet orifice ( 37 ) of the racking device ( 33 ).
