Abstract
Abstract An elongated separation chamber for conducting a fluid medium and having a peripheral wall with discharge openings provided in this wall. A motion imparting member is arranged in the region of the inlet of the separation chamber and is operative to cause the fluid medium to move within the separation chamber along a helical path towards the outlet of the chamber so that solid particles suspended in the fluid medium are moved along and against the peripheral wall and are thereby forced through the discharge openings in the wall while the fluid medium is discharged via the outlet of the chamber.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
170 words
Apparatus for separating solid particles from a fluid medium, comprising, in combination, an elongated separation chamber having a peripheral wall provided with a plurality of circumferentially spaced elongated slots extending in the direction of the elongation of said separation chamber, said separation chamber having an inlet portion at one end and an outlet at the other end thereof; means for introducing a fluid medium having solid particles suspended therein through said inlet portion of said separation chamber into the latter; motion imparting means arranged in said inlet portion for causing said fluid medium to move within said elongated separation chamber along a substantially helical path toward said outlet so that said solid particles present in said fluid medium are moved along and against said peripheral wall and pass through said elongated slots therein while said fluid medium will flow through said separation chamber and leave the same through said outlet thereof; and jacket means surrounding said peripheral wall and defining therewith an annular clearance with which said elongated slots communicate.
Claim 2
Dependent Claim
170 words
Apparatus for separating solid particles from a fluid medium, comprising, in combination, an elongated separation chamber having a peripheral wall provided with a plurality of circumferentially spaced elongated slots extending in the direction of the elongation of said separation chamber, said separation chamber having an inlet portion at one end and an outlet at the other end thereof; means for introducing a fluid medium having solid particles suspended therein through said inlet portion of said separation chamber into the latter; motion imparting means arranged in said inlet portion for causing said fluid medium to move within said elongated separation chamber along a substantially helical path toward said outlet so that said solid particles present in said fluid medium are moved along and against said peripheral wall and pass through said elongated slots therein while said fluid medium will flow through said separation chamber and leave the same through said outlet thereof; and jacket means surrounding said peripheral wall and defining therewith an annular clearance with which said elongated slots communicate.
Claim 3
Dependent Claim
40 words
Apparatus as defined in claim 1, wherein said elongated separation chamber is in the form of a cylinder of uniform diameter and wherein said elongated slots extend longitudinally from said inlet portion to said other end of said separation chamber.
Claim 4
Dependent Claim
43 words
Apparatus as defined in claim 1, wherein said annular clearance at the lower region thereof includes a portion forming a collecting chamber for said solid particles, said collecting chamber comprising discharge means for discharging the thus collected solid particles from said collecting chamber.
Claim 5
Dependent Claim
14 words
Apparatus as defined in claim 3, wherein said discharge means is a worm conveyor.
Claim 6
Dependent Claim
14 words
Apparatus as defined in claim 3, wherein said discharge means is a discharge pump.
Claim 7
Dependent Claim
40 words
Apparatus as defined in claim 1, wherein said motion imparting means includes a plurality of vanes operative to impart a substantially radially outward motion to said fluid medium to cause the same to move along said substantially helical path thereof.
Claim 8
Dependent Claim
14 words
Apparatus as defined in claim 6, wherein said plurality of vanes are helically shaped.
Claim 9
Dependent Claim
24 words
Apparatus as defined in claim 6, wherein said motion imparting means includes guide means for guiding said fluid medium into engagement with said vanes.
Claim 10
Dependent Claim
29 words
Apparatus as defined in claim 8, wherein said guide means has a cone-shaped circumference, and wherein said plurality of vanes project radially of said cone-shaped of said guide means.
Claim 11
Dependent Claim
21 words
Apparatus as defined in claim 9, wherein said plurality of vanes are unitary with said cone-shaped circumference of said guide means.
Claim 12
Dependent Claim
15 words
Apparatus as defined in claim 10, wherein said vanes and said guide means are stationary.
