Definitions

  • This invention relates to the extraction of liquid by mechanical means from masses of material which consist of very finelydivided, especially colloidal, substances, such as peat.
  • Devices for this purpose may be constructed ,in various ysa a t
  • the movement bet'ween ;the material being pressed and the sieve should be effected in an inclined direction over the sieveand thesieve consist of: parallel spaces ofsucha width that mainly only the liquid squeezed out from the pressgoods is transmitted but'no part of the material itself.
  • Fi .ure8 is a fragmentary yiew of Figure 6 toa argerscale.
  • the essential features of the bars 6 or the discs 6 consists therein that they are arranged at such an angle to the direction of the pressure that the pressure within the press chamber 3 against the surfaces of the bars or discs facing each other tends to diminish the width of the space between them, whereas a pressure on the opposite side of the sieve from the chamber 11 tends to augment the width of said space.
  • the bars 6 or the discs 6 are therefore not immovably secured to their support (7, 7 8 or 9) but are secured in such a manner that they have a limited amount of movement.
  • the liquid extracted from the pressed material is discharged from the interior of the cylinders by means of a suitable discharging device (not-shown) and through the pipe 24 liquid or air may be introduced into the spaces, which lead out from the chamber 20, for their blowing out or scavenging.
  • any suitable device such as a mud pump, may be used.
  • Figure 6 shows a modified arrangement according to which the discs 6 abut at their outer ends towards a concentric wall 25 enclosing the chamber 3, in which a conveyor screw 26 presses the goods from the inlet 1 to the outlet 4.
  • Pipes 27 opening into the space 29 between the discs 6 by means of branch pipes 28 are provided.
  • the discs 6 are provided with holes 30, through which the spaces 29 are put in communication with one another and with the branch pipes 28.
  • Figure 7 illustrates a section of the same arrangement as shown in Figure 6, except that the discs 6 are substituted by longitudinal laminae 6 which are held in place by means of wire rings 31 or the like.
  • the sieve elements in the form of discs or slats closely abut each other at their ends adjacent to the press chamber. According to the fact that the surfaces of said rings or slats even in a well-ground condition are not perfectly smooth, but are provided with small cavities and projections, the spaces between said cavities and projections form small channels for the escape of the water pressed out from the material.
  • the sizes of these channels are automatically adjusted according to the pressure of the press material with the aid of overlapping surfaces of the sieve elements, on which the pressure acts so that the sieve elements are compressed more or less in accordance with the variations of said pressure.
  • a press for extracting liquid from a mass of finely divided solid material
  • a press chamber means for applying pressure to the material therein
  • a plurality of movably mounted sieve elements arranged in louvre like formation inclined to the radii of the press chamber, and closely abutting on their inner edges, the adjacent surfaces of said elements converging towards one another
  • said elements 7 nally within the press chamber, said elements 7 the spaces betweensaid elements being varied inversely in accordance with the pressure applied to the material in the press chamber.
  • a press chamber means for applying pressure to the material therein, a plurality of movably mounted sieve elements arranged in louvre like formation inclined to the radii of the press chamber and abutting but overlapping on their inner edges, the adjacent surfaces of said elements converging towards one another, the spaces between the elements being varied mversely in accordance w1th the pressure applied by the material on the said overlapping inner edges.
