Definitions

  • My invention relates to improvements in straining presses for extracting liquids from moist substances of various kinds and more particularly to presses of the type having a press chamber of annular cross section through. which the material is passed, said chamber being mainly composed of two cylinders, one of the latter or preferably both "being perforated and the moist substances being continuously fed'and squeezed through the space between said perforated cylinders.
  • the object of my invention is to provide a press of this character which is very simple in its construction. containing no complicated parts as worms safety couplings gear wheels and the like, and which can be manufactured, sold and .maintained its place by means of a ring 11 surroundlng at comparatively low cost.
  • Another object of my invention is to thus design the feeding and discharging mechanism that the pressing action and the amount of material under treatment. will be kept automatically practically constant during the whole operation of the press.
  • Fig. 1 is a vertical sectional view'of the pr Figs. 2, 3, a
  • nd 4 are. similar sectional views showing three modified forms of the feeding and actuating mechanism.
  • annular press chamber 1 comprises twowalls 2, 3 which are in their preferred form cylindricalybutwhich. can be made conical or in part conical andin part cylindrical; withthe essence of my invention,
  • the extractedliquid is discharged. through the outlet ports 17, 18*, while the material after treatment is discharged at the .dis-
  • Y I prefer to mount the scrapers 12 so as to atively to the press chamber and so as to project to a larger or smaller extent into the discharge port 13.
  • controlling mechanism for the scrapers 12 consists of a lever 15, engaging the carrier 14, the latter being slidably mounted on the shaft 7.
  • Figs. 2 and 3 show straining presses ac-- cording to this invention but of modified constructioi'i in which the inner straining member 3-is tiltably mounted upon its-carrier and is postively actuated to its rotary tilting motion.
  • the means for imparting. apositive tilting motionto the inner straining member, 3 comprises a rotating eccentric 1-7 engaging the hub 9 of the straining member? within: the rigidly mounted bearing '18. Said tilting motion of the shaft is trans-- mitted in turn to the inner straining cylinder 8.
  • the construction and! the WOIlTlIlgCOlldltlOIlS of this modified press. are identical to-that outlined in. connection with Fig. 1'. I
  • the outer straining member 2 may. be given. a positive tilting motion e. g; through a' rotary driving mem ber' engaging the head of said cylinder 2 at its innner periphery by means of a roller or a. similar element
  • the said roller shouldbe" arranged so as to be closely before or behind the feeding thumb 8 with regard to its respective position on-the'shaft 7 and-thedirection olrotation. of the latter, the object being-to provide an. enlarged. in take space in due register'withw thefeeding action.
  • the discharging knives which operate in the outlet end of the annular pressing space and serve to scrape the material out of the same, are axially shiftable in the same manner as the pressingthumb 8,.which1makesit possible to:reg ulate the pressure in the pressing space.
  • thepnessinggdevice 8 and discharging scrapers 12 are positively connected together by a system of levers in sucha" manner that with the automatic withdrawah of the pressing devicethe discharging scrapers are simultaneously movedin' the same direction.
  • the system oflevers consistsof the. lever 26 which is pivoted to "the frame ofthe press at and” whose free lubly mounted upon the shaft "If the ID'OVBDIQDi) of the material in the-pressing spaceis stopped by an increase-in pressure,
  • the pressing device rises which raises the lever 26 and causes the discharging, scrapers to penetrate, deeper" into the outlet end; of the press; thereby increasing: the discharge of material from the pressing space,
  • the pressure in. the pressing space returns to normal, the. pressing thumb sinks ..again, forcing, the scrapers 12back. to their normal operating position- Thecenter of he tilting motion which. is
  • a straining press comprising a. pair of cages one inside the other and forming between theme space for the reception of material tobe pressed andgnieans for rela tively tilting saidl cages.
  • a straining press comprising apalir. of cylindroidal cages of 1 different diameter mounted one inside the. other. and: forming between them an annular space fonthe reception of material to be pressed, and means for relatively. tilting; said. cages ti k :strainingv press comprising a pair-of cylindroidal cages of different diameter mounted. one inside the other. andI-fonming; between them an annular space for the resaid annular space is progressively squeezed and compressed in a transverse direct1on.
  • a straining press comprising .apair of cylindroidal cages of different'diameter mounted one inside the other and forming between them an annular space for the reception of material to be pressed, means for tilting one of said cages, and a circular guide surrounding said tilting cage at the transverse plane where its'tilting motion is Zero.
  • a straining press comprising a pair of cylindroidal cages of different diameter mounted one inside the other and forming between them an annular space for the reception of material to be pressed, a revoluble shaft, an eccentric on said shaft,
  • Astraining press comprising a pair of cylindroidal cages of different diameter I mounted one inside the other and" forming between them an annular space for the reception of material to be pressed, one of said cages being freely tiltable, means for feeding material to be pressed into one end of said annular space, and a pressing thumb working at the intake end of said annular space and adapted to be moved around the same for pressing in new material to be pressed, whereby said tiltable cage'is tilted so as to squeeze the material in the side of said annular space opposite to said thumb in a substantially transverse direction.
  • a straining press comprising a pair of cylindroidal cages of different diameter mounted one inside the other and forming between theman annular space for the reception of material to be pressed, said cages being tiltably mounted, means for feeding material to be pressed into one end of said annular space, a revoluble shaft within said cages, an eccentric on said shaft, an eccentric ring cooperating with sand eccentric and rigid with one of said cages, a pressing thumb secured on saidshaft so as to rotate I therewith and extending into the intake end of said annular space, the point' of said eccentric furthest from the axis of said shaft f being opposite to said pressing thumb.
