Definitions

  • the invention relates to a drainage element for presses for separating liquids from solid substances, in particular for fruit presses, comprising a rod-shaped, flexible drainage core with flow paths for draining the squeezed-out liquid from the press space and a liquid-permeable filter sleeve surrounding the drainage core, at least one end of the drainage element is attached to a juice collecting plate, pressure plate or to the press jacket of the press, and a rubber-elastic cuff surrounding the drainage core in the fastening area and on a free section adjoining it.
  • Fig. 1 shows a longitudinal section through the known attachment of a drainage element in a fruit press.
  • a plurality of drainage elements 3 are arranged in a press space 2, which is delimited by a pressure plate 1, in a known fruit press (not shown).
  • a drainage element 3 consists essentially of an elastic drainage core 4, via the external grooves 5, as the section AA shows, the liquid is led out of the press chamber 2 during the pressing process, and a stocking-shaped filter 6 for solid-liquid separation stretched over it.
  • the drainage core 4 and the filter 6 are fastened in a core holder 7 at the ends of the drainage element 3.
  • the filter 6 will passed over an elastic cuff 8 and fixed with an O-ring 9.
  • a disc 10 serves to support the cuff 8 against a cross pin 11 which is pushed laterally into bores in the drainage core 4 and the core holder 7, thus ensuring the axial and radial fixation of the two components 4 and 7 to one another.
  • the core holder 7 is connected to the pressure plate 1 by means of a spacer bush 12 and a locking ring 13.
  • a cam 14 of the locking ring 13 which engages through a slot 15 in the spacer bush 12 into a groove 16 of the core holder 7, in conjunction with a collar 17 of the spacer bush 12 lying behind the pressure plate 1, secures against axial displacement.
  • the invention has for its object to avoid the disadvantages mentioned by a device of the type mentioned.
  • this object is achieved by at least one support element for the cuff, which is connected to the cuff in such a way that its deformability in a partial area located in the fastening area is severely restricted compared to the remaining part.
  • the support element is designed as a sleeve with high bending rigidity. Further preferred embodiments are characterized in the claims.
  • FIG. 2 shows a cuff 8 'similar to the type already shown and explained in FIG. 1.
  • a metal sleeve 23 is inserted into the cuff 8' as a support element, and the connection between the metal sleeve and the cuff can be detachable or fixed.
  • the metal sleeve 23 closes in the fastening area of the drainage core 4 according to.
  • the length of the zone 24 is approximately equal to or less than the jacket thickness 45 according to the fastening area of the drainage core 4.
  • the metal sleeve 23 eliminates the disadvantages of the known drainage element mentioned above in connection with FIG. 1, namely the deformations on the grooves 5 for the drainage and the extraction of the rubber-elastic cuff 8 and the filter 6 between the core holder 7 and the drainage core 4.
  • a sleeve 26 which lies partly inside the cuff 8'.
  • the sleeve 26 projects axially over the cuff 8 'at its end by a piece of length 27.
  • the resulting protruding edge serves for better force introduction from the cross pin 11 according to FIG. Fig. 1 for support in the sleeve 26.
  • the disc 10 can be omitted.
  • Fig. 4 shows a variant of the cuff 8 ', in which the supporting sleeve 28 is flanged on both sides.
  • the resulting edges 29, 30 improve the introduction of force into the sleeve 28.
  • FIG. 5 shows a cuff 8 ′′ with a support element 31.
  • the support element 31 assumes part of the functions of the cuff 8 'according to FIGS. 2-4.
  • the support structure is now achieved by connecting the molded parts 8 ′′ and 31 with different deformation properties.
  • the support element 31 is made of a rigid plastic and is connected to the elastic cuff 8 ′′ by a snap lock 32. This structure allows the replacement of damaged cuffs 8 '', the support element 31 being reusable.
  • Fig. 6 shows a cuff 8 ', in which a sleeve 36 is inserted as a support element so that an axial fixation occurs.
  • a sleeve 36 is inserted as a support element so that an axial fixation occurs.
  • FIG. 7 shows a connection part for the drainage element 3 in the pressure plate 1, in which the filter 6 is fixed between two conical components 37, 38.
  • the drainage core 4 is surrounded by a cuff 8 '' ', in which a sleeve 23' is inserted as a support element.
  • FIG. 8 shows a connecting part similar to that according to FIG. 7, the conical component 38 having a sleeve 23 ′′ as a supporting element for the cuff 8 ′′ ′′ being made from one part.
  • This embodiment facilitates assembly and makes the cuff 8 '' 'cheaper as a wearing part.
