Definitions

  • This invention relates to an apparatus for the continuous lixiviation of disintegrated or comminuted par ticularly vegetable or animal material, comprising an inclined trough provided at its lower end with a supply chute for the said material and containing a plurality of helical conveyors rotatable about axes parallel to each other and to the generating line of the trough wall and constructed with passage openings for the lixiviation liquid, said conveyors in axial projection filling substantially the full cross section of the trough.
  • the axes of the screw conveyors are located substantially horizontally side by side.
  • the known apparatuses with a plurality of screw conveyors have certain limitations to their function which are of some disadvantage in practical operation.
  • a further consequence of this is that there is practically no other possibility of varying the capacity of the apparatus than varying the speed of rotation of the screws, and this is only feasible within certain limits, because the time of travel of the material from one end of the trough to the other, and thereby the time in which it is subjected to lixiviation, will otherwise vary too much.
  • the lower limit of the capacity of such an apparatus amounts to about 70% of the nominal capacity. However, it may frequently be desirable to be able to go down to a considerably lower capacity.
  • the principal characteristic of the invention is that the axes of the helical conveyors are located in pairs vertically or atent O 3,235,338 Patented Feb. 15, 1966 substantially vertically above one another at a mutual distance substantially equal to and at any rate not exceeding the sum of the radii of the outer contours of the two helical conveyors, the trough wall being shaped substantially to match the combined contour of the helical conveyors.
  • An apparatus constructed in this manner is capable of satisfactory operation as soon as the cross sectional zone of the trough covered by the lower screw conveyor (or conveyors) is filled with material, i.e. a satisfactory, uniform lixiviation may be obtained even if the upper screw conveyor (or conveyors) runs completely or partly idle.
  • a satisfactory, uniform lixiviation may be obtained even if the upper screw conveyor (or conveyors) runs completely or partly idle.
  • the capacity may be increased to a certain limit by increasing the speed of rotation.
  • the upper screw conveyor (or conveyors) may be put in operation, too, and this may then, if desired, also be completely filled, the speed of rotation being again reduced to the minimum value, and the number of revolutions being subsequently increased gradually as the capacity requirements increase.
  • the capacity in this manner it is possible to control the capacity as far down as to 30% of the nominal capacity.
  • the screw conveyors of each pair located one above the other, should interengage slightly. A more pronounced interengagement is not necessary in order to secure a satisfactory feeding, and would therefore only result in an unnecessary increase of the friction between the material and the helical windings and an unnecessary stirring of the material whereby it would also be more difficult to carry out feeding by the lower screw conveyor (or conveyors) alone without disturbances occurring from the upper screw conveyor (or conveyors).
  • the material supplied to the apparatus has a natural tendency to remain on the surface of the lixiviation liquid and consequently to be conveyed by the upper screw conveyor (or conveyors)
  • the supply chute at least at its lower end, with separate supply paths for the supply of comminuted material to the zones of the upper and the lower helical conveyor respectively, the supply path to the lower zone containing feeding means for supplementing the feeding movement produced by the gravity of the material.
  • the material will be supplied predominantly to the lower screw conveyor (or conveyors) and will begin to fill the zone of the upper screw conveyor only when the zone of the lower screw conveyor has already been completely filled.
  • a guide plate is provided at the lower end of the chute, said guide plate extending downwards at an inclination in the feeding direction from a transverse line in the zone of the chute to a portion of the shaft of the upper helical conveyor constructed without helical windings.
  • the lower screw of each pair and the upper screw of the same pair, or at least the section of the latter screw located beyond the guide plate may have the same directions of rotation.
  • the upper screw conveyor or conveyors
  • the upper screw conveyor will contribute to a particularly great extent to the above mentioned smoothing of the surface of the filling of material under the operating condition where the zone of the upper screw conveyor (or conveyors) is only partly filled.
  • the distance between the planes of the axes of any two adjacent pairs of screw conveyors may, according to the invention, advantageously be smaller than the sum of the radii of the outer contours, as viewed in axial projection, of the two juxtaposed screw conveyors, while at the same time the two pairs of screws have winding-s of opposite pitch and opposite directions of rotation.
  • the best possible feeding of the material in a uniform manner and in a uniformly packed state is obtained in each of the screw conveyor levels.
  • the section of the upper screw conveyor of each pair located under the inclined guide plate and on the proximate side thereof, as viewed in the feeding direction may, according to the invention, be terminated by a conical screw tapering towards the guide plate.
  • the section of the upper screw conveyor (or conveyors) located under the inclined guide plate and on the proximate side thereof, as viewed in the feeding direction with a pitch different from that of the section of the same screw conveyor (or conveyors) located beyond the guide plate.
  • a further possibility of controlling the relative proportion of the feeding of material to the lower and the upper screw conveyors may be obtained, according to the invention, by so arranging the apparatus that the direction of rotation and the speed of rotation of the section of the upper screw conveyor of each pair of screws located under the inclined guide plate and on the proximate side thereof, as viewed in the feeding direction, are independent of the direction of rotation and the speed of rotation, respectively, of the section of the same screw conveyor lo cated beyond the guide plate.
  • substantially prismatic filling bodies may be provided between adjacent pairs of screw conveyors at the level of the borderline between the zones of operation of the upper and lower screw conveyors, respectively.
  • the filling bodies may also be rendered useful by being provided with heating or cooling means, e.g. by being hollow and provided with inlets and outlets for a heating or cooling medium.
  • heating or cooling means e.g. by being hollow and provided with inlets and outlets for a heating or cooling medium.
  • a particularly eflicient exchange of heat will be obtained because this exchange takes place in the interior of the material being fed so that it is not necessary, as in the known apparatuses, to limit the heat exchange to the circumferential surface.
  • a partition may, according to the invention, be provided in the supply chute, said partition extending upwards from the guide plate substantially at right angles to the axes of the screw conveyors, and, according to a special embodiment of the invention, the said partition, or part of same, may form a closure for the supply chute to the upper screw conveyors, located above the guide plate, said closure being rotatable about an axis extending transversely of the trough about or at the level of the upper edge of the said guide plate.
  • FIG. 1 shows a longitudinal vertical section through the apparatus
  • FIG. 2 a cross section along the line II-1I in FIG. 1, and
  • FIG. 3 is a diagrammatic view showing the prismatic body.
  • 1 is a slightly inclined trough-shaped container, to the lower end of which a supply chute 2 is connected.
  • Two pairs of screw conveyors 3, 3a and 4, 4a are provided in the trough.
  • the axes 5, 5a and 6, 6a of the two screws of each pair 3, 3a and 4, 4a, respectively, are located vertically above one another.
  • the two upper screw conveyors 3a and 4a are located horizontally side by side, as viewed in cross section, and the same applies to the two lower screw conveyors 3 and 4.
  • the two screws of each pair interengage slightly only whereas considerable engagement exists between each two screws located horizontally side by side.
  • the outer contour of the trough matches the outer contour of the four screws at the bottom and on the side.
  • the lower screw B or 4 of each pair and the upper screw 3a and 4a respectively of the same pair have the same directions of rotation while the two pairs of screws 3, 3a and 4, 411, respectively, have windings of opposite pitch and opposite directions of rotation as indicated by arrows in FIG. 2.
  • a partition 7 which extends substantially at right angles to the shafts of the screw conveyors and from the lower edge of which an inclined guide plate 8 extends downwards to a section 9 of the shafts of the upper screw conveyors where no screw blades are provided.
  • the upper screws are terminated with conical screw blades 10.
  • conical screw blades 10 Thereby these screw blades urge the material supplied to them forwards against the underside of the guide plate 8 whereby the material is caused to slide along the guide plate to the zone of the lower screws.
  • the conical shape of the screw blades 10 Owing to the conical shape of the screw blades 10, the operating zone of the latter is extended to the immediate neighbourhood of the guide plates so that a movement is imparted to the material along the guide plate whereby there will be no danger of the accumulation of material.
  • the conical screw blades 10 may be rigidly attached to the shafts 5a and 6a or they may be rotatably mounted thereon and provided with driving means of their own. In the latter case they may be rotated at a difierent speed from or even in the opposite sense than the main portions of the screw conveyors 3a and 4a. In this manner the feeding of material to the upper screw conveyors may at will be accelerated or retarded relative to the feeding of material to the lower screw conveyors in order to obtain optimum operating conditions.
  • the screw blades may have a pitch different from that of the main portions of the screw conveyors 3a and 4a.
  • the part of the partition 7 above the upper edge of the guide plate 8 may, if desired, be rotatable to the right (as viewed in the drawing) so that the supply of material to the upper screws may be completely stopped.
  • substantially prismatic hollow filling body 11 which may be constructed with an inlet and an outlet for a heating or cooling medium.
  • the apparatus is provided at its upper end with an inlet for the lixiviation medium, not shown, and with means, not shown either, for removing the lixiviated material, e.g. rotating conveyor blade-s, screws or bucket elevators, and at the lower end of the apparatus an outlet, not shown, for extract is provided.
  • the material tobe lixiviated is supplied to the container 1 through the chute 2 and is fed upwards through the inclined container 1 by means of the screw conveyors 3, 3a and 4, 4a and encounters the lixiviation medium supplied to the upper end of the container in counter current, the said lixiviation medium flowing substantially axially through the container under the influence of its gravity, the extract thereby formed encountering material with a constantly increasing content of extractable matter until the final extract is discharged from the zone where fresh disintegrated material is supplied.
  • the apparatus operates substan tially as previously described.
  • a lixiviation apparatus may, according to the invention be constructed in various ways. Instead of two pairs of screws it may e.g. be constructed with one pair of screws only, and it may also comprise more than two pairs of screws. It will be understood that, for a certain outer diameter of the screws and a certain total width of the trough, a doubling of the capacity may be obtained as compared with the known apparatuses in which screw blades are provided at one level only, and from this maximum capacity, a substantial reduction may be obtained by arranging for the feeding to be effected by the lower pair of screws only, while at the same time causing these to rotate at the minimum speed of rotation permissible.
  • the apparatus is primarily intended for the extraction of vegetable or animal material, but it is entirely possible to use it for other extraction or washing processes or e.g. for the chemical treatment of minerals with solutions.
