Definitions

  • This invention relates to presses, particularly worm presses, for the treatment of moist materials, for instance oil containing materials, of the kind in which the material is continuously passed through a pressing chamber narrowed towards the discharge end, and the oil or other fluid expressed escapes through the walls of the pressing chamber.
  • Presses of this kind with pressing chamhers narrowing toward the discharge end have been built heretofore, in which either the pitch of the worm thread has been decreased -or the worm shaft diameter in creased towards the discharge end of the press. This has certain disadvantages, especially because of increased friction, which disadvantages are overcome by the present invention.
  • the pressing chamber comprises a series of compartments of progressively reduced diameters connected y tapering passages, the oblique internal surfaces of which passages have a damming action on the material passing from one compartment to the next.
  • the thread of the worm is interrupted at the tapering passages so that the material progresses in these parts, where it passes from a certain chamber to the next chamber of a higher pressure, in a straight axial direction.
  • Figure 2 represents -a vertical section taken on the line AB in Figure 1.
  • compartments or constituent pressing chambers there are several compartments or constituent pressing chambers, four such compartments being illustrated and respectively marked 2, 3, 4 and 5, these compartments being in this example cylindrical situated only in the compartments 2, 3, 4, 5
  • the material to be treated passes from the inlet 10 into the feed chamber 11, the walls 12 of which may he hinged as seen in Figure 2 in order to facilitate access to the interior of the apparatus for cleaning or other purposes. These walls 12 are rovided with perforations 13 ( Figure 2) or the esca e of the oil or other fluid component of t e material treated.
  • the said material is passed by the worm 9 from the chamber 11 into the compartment 5' and on reachin taneous discharge of fluid through the perforations in the compartment 5.
  • the compressed material is then pushed by the worm 9 into thecompartment 4, where its pro ess the oblique wall 6 is compressed, with sim so! is again dammed at the oblique wall so that it is further compressed, then'passes into the compartment 3 and is again dammed and compressed at the oblique wall 8, then pushed into the compartment 2 from which it finally escapes through the annular passage 14.
  • the invention is obviously capable of being carried out with several variations, for instance, instead of the strainer or pressing chamber being constructed with perforated walls, it may be made of rods between which the expressed fluid can escape. Instead of the walls of the compartments being cylindrical they may be cylindro-conical. .
  • the pressing device is a worm
  • the blades thereof in the different compartments may be of equal sizes, or of different sizes.
  • a press of the character described comprising a pressing chamber with a plurality of compartments of progressively decreasing average diameters andwith perforated Walls,
  • compartments being connected by tapered passa es; and a worm with substantially cylin rical shaft, thethread of the worm being discontinued and said shaft being left blank at the passages.
  • a press of the character described comprising a pressing chamber made up of a glurality of compartments of progressively I ecreasing average diameters, said' compartments being connected by tapered passages,
  • A-press o the character described in- 4 eluding a pressing chamber, successive points of maximum pressure and of relatively lower pressure in said chamber, a driven shaft in said chamber, feeding means on said shaft, said feeding means being discontinued and said shaft being left blank at said points of maximum pressure.
