Definitions

  • the invention relates to a drainage element for presses for separating liquids from solid substances, in particular for fruit, grape or fruit presses, consisting of a core which is fastened in a socket connected to the container shell and is in the form of a rod and is surrounded by a liquid-permeable filter sleeve.
  • a larger number of such drainage elements is arranged, for example, in the pressing chamber of a fruit press having a pneumatically actuated membrane on the container wall above or below the juice collecting channels.
  • the flexible drainage elements protruding into the press room are deformed.
  • the squeezed juice penetrates the filter cover of the drainage element and is guided out of the press chamber along the rod-shaped core and directed into juice collection channels.
  • the respective end of the drainage element is detachably fastened in a socket connected to the container wall, the core provided with longitudinal grooves for transporting the liquid protruding into a juice collecting channel.
  • a sleeve which closely surrounds it and which has a flanged edge at the end facing away from the pressing chamber and between which and the socket the stocking-like filter cover which is flushed around the latter is clamped, the latter securing the core in the axial direction by a latter penetrating pin and against the flanged edge of the sleeve and between the end of the Core and the bottom of the juice collection channel an insert is provided.
  • a disadvantage of this known embodiment is that the filter sleeve in the area of the transition point, where the drainage element protrudes from the socket into the pressing space, is pressed by the pressing pressure into the longitudinal drainage grooves of the core and thus impair the drainage. At this point, the frequent movements of the core result in high wear and tear.
  • the invention has for its object to avoid the disadvantages mentioned and to provide a fastening of the drainage element, the manufacture of which is simple and allows rapid assembly and functionality.
  • the retaining ring is arranged in an annular groove provided on the sleeve or the socket. This enables a compact design to be achieved.
  • the retaining ring is designed as an O-ring.
  • the sleeve is made of an elastic material.
  • the annular groove provided in the sleeve preferably has an insertion angle ( ⁇ ) which is approximately at right angles to the pulling direction of the filter sleeve.
  • the insertion angle ( ⁇ ) is greater than 90 °.
  • the sleeve has an outer cone tapering in the direction of the press chamber, which cooperates with a corresponding inner cone of the socket, the filter sleeve being arranged between the socket and the socket.
  • the sleeve is axially secured in the direction of the liquid collecting space by means of a releasable pin which is arranged at the end of the core and passes through a hole in the core and the socket.
  • An end plate is expediently arranged between the sleeve and the pin.
  • the retaining ring or the O-ring takes over the function of sealing the solids from the pressing chamber.
  • the advantages achieved with the invention also consist in the fact that, due to the wedge effect of the O-ring, the holding force increases with increasing tensile force on the filter sleeve and thus a secure fastening is ensured even with high tensile forces.
  • the construction of the attachment allows a thin-walled design of the socket, in which the drainage element is used for anchoring. This results in low material costs and an inexpensive manufacture.
  • the assembly and disassembly of the filter cover is simplified and facilitated.
  • a plurality of drainage elements 2 are arranged in a press chamber 1 of a fruit press (not shown in more detail).
  • Each drainage element 2 consists of a rod-shaped, flexible core 3, which is surrounded by a stocking-like filter cover 4.
  • the ends of the drainage element 2 are each inserted in a socket 6, which is arranged axially immovably in a passage opening 7 of the container shell 5.
  • the socket 6 protrudes with its longer part into a liquid collecting space or juice collecting channel 8, which is delimited by a wall 9 or U-shaped.
  • a pin 10 is provided, each of which penetrates a hole in the socket 6 and the core 3.
  • a pressing member for example a membrane, is moved against the container wall 5, the flexible drainage elements 2 buckling and the squeezed juice passing through the liquid-permeable filter sleeve 4 to the core 3 and being conducted via liquid channels in the core 3 into the liquid collecting space or juice collecting channel 8.
  • an elastic sleeve 11 is pushed onto the end of the core 3 and has an outer cone 12 that tapers in the direction of the press chamber 1.
  • the end of the filter sleeve 4 is pulled over the sleeve 11 and held in an annular groove 14 of the sleeve 11 with a retaining ring designed as an O-ring 13.
  • the drainage element 2 is pushed into the socket 6 from the side of the container wall 5 facing away from the pressing chamber 1 until the outer cone 12 of the sleeve 11 with the coated filter sleeve 4 comes to rest against a corresponding inner cone 15 of the socket 6.
  • an end plate 16 is pushed onto the core 3, to which the pin 10 connects, which axially secures the sleeve 11 on the core 3 and, as already described, fixes the end of the drainage element 2 in the socket 6.
  • the annular groove 14 in the sleeve 11 has an insertion angle ( ⁇ ) of approximately 90 ° (FIG. 2).
  • the O-ring 13 inserted into the annular groove 14 and covering the filter sleeve 4 is held in the annular groove 14 by the inner wall of the socket 6.
  • considerable tensile forces arise at the attachment point of the filter cover 4, which act in the direction of the arrow 17 in FIG. 3.
  • an elastic deformation occurs on the front flank 18 of the annular groove 14 in the direction of pull, as shown in FIG. 3.
  • the O-ring 13 rolls on the inner wall of the socket 6 in the pulling direction 17 of the filter sleeve 4 (arrow 19 in FIGS. 2 and 3) and is deformed so that it acts as a wedge and braces the filter sleeve 4 against the flank 18 of the annular groove 14.
  • the tension increases with increasing tensile force, so that a secure attachment of the filter cover 4 is ensured even with very high forces.
  • the insertion angle ( ⁇ ) of the annular groove 14 is selected to be greater than 90 ° (FIG. 4) in order to increase the wedge effect of the O-ring 13 when tensile forces occur achieve.
  • a wedge opening is formed between the flank 18 of the annular groove 14 and the inner wall of the socket 6, into which the O-ring 13 by rolling (arrow 19) on the inner wall of the socket 6 when the filter sleeve 4 is subjected to tensile forces is drawn in and deformed into a wedge, which braces the filter sleeve 4 against the flank 18 of the annular groove 14.
