Definitions

  • the invention relates to an apparatus for extracting liquid from liquid-containing material, such as oil from oleaginous vegetable material, of the type described in U .S. Patent No. 2,724,327.
  • the material which has been comminuted more or less, is fed to the gap between two counter-rotating rollers with grooved, or at least rough, and continuous cylindrical surfaces via a supply space which is bounded by the surface of one of the rollers and the concave surface of a curved guide plate placed eccentrically relative to this surface, in such a way that'the supply space gradually narrows towards the gap between the rollers and the pressure in the material thus increases, but without the latter becoming so high that an appreciable quantity of liquid is expressed from the material before it has reached the gap between the rollers.
  • the guide plate Shortly before this latter the supply space, after a narrowest passage, has a widening over some distance, while near the widening and the narrowest passage the guide plate has been provided with outlet means for the liquid, preferably consisting of slotshaped passage openings. This enables the liquid expressed between the rollers to escape against the supply direction of the material.
  • the invention aims at an improvement of such an apparatus, which consists in that, in front of the said narrowest passage, the guide plate has been provided with liquid outlet openings. This makes it possible to increase the pressure on the material between the first roller and the curved guide plate to a value at which liquid is expressed without the liquid flowing out obstructing the supply of the material, as would be the case in the known apparatus if the pressure in the material in the supply space were increased.
  • Figures 1 and 2 illustrate a vertical and a longitudinal cross-section respectively through an apparatus according to the invention.
  • the apparatus consists of two cooperating horizontal rollers l and 2 with continuous but rough surfaces, e.g., provided with longitudinal grooves, which rollers are supported in the frame members 3, 4 and are each provided with their own drive 5 and with a toothed wheel respectively, which cooperates with a pinion 6 for rotation in opposite senses.
  • a concave, preferably polished guide plate 8 Facing the roller 1, at some distance from it a concave, preferably polished guide plate 8 has been provided, which at the lower end rests against a beam 9, from which extend a number of parallel pressing rods 10 of triangular cross-section, which enclose downwardly widening passages 11 and whose upper surfaces form a smooth continuation of the inner surface of the guide plate 8, so that they form therewith a continuous guide surface, which is provided with slot-shaped liquid outlet openings.
  • the position and the curve of this guide surface are such that the supply space for the material, enclosed by this surface and the corresponding roller surface, gradually decreases in width in the direction of the gap between the rollers, but after a point of narrowest passage, shortly before the gap, gradually widens again.
  • the beam 9 with the pressing rods 10 is mounted on a frame 12, provided underneath the pressing rods and having bottom outlets 13 and supporting ribs 14 for the pressing rods 10, this chamber being movable about a longitudinal axis 16 by means of hydraulic jacks 15 mounted in the foot of the frame, with a view to adjusting the pressing rods and the guide plate relative to the roller 1, i.e., adjusting the shape of the supply space for the material.
  • a liquid separator consisting of an angle piece 18 lying with its open side against the pressing rods and resting on a base plate 19, the horizontal limb of this angle piece and said plate being provided with coinciding passage openings for the discharge of the liquid expressed between the rollers, which flows back via the above mentioned widening.
  • the material to be expressed is introduced above the roller 1 into the apparatus via an oblong filling tube 20 and drops on to the clockwise rotating roller 1, by whose roughened surface it is fed to the mouth of the supply space between guide plate and roller, while being laterally enclosed by the flanges 21.
  • This supply is con trolled by means of an adjusting valve 23, which is freely rotatable about an axis 22 and with which the upper edge of the plate 8 is pivotally connected. Near this upper edge of the plate 8 is acted upon by a supply-adjusting member 24 constructed in the form of a screw.
  • An apparatus for extracting liquid from liquid-containing material such as oleaginous material comprising two rotary rollers with continuous, irregular, cylindrical surfaces arranged in opposed relationship and adapted to exert expressing pressure on material passing therebetween and a curved guide plate extending around a substantial portion of the peripheral surface of one of said rollers in closely spaced but eccentric relationship thereto and terminating adjacent the nip of said rollers, said plate and the roller surface defining a smoothly and gradually 3 4 plate and surface cooperating to exert pressure on said the rollers having outlet openings therein to discharge material therebetween to express liquid therefrom in fluid expressed in said tapering passageway.
