Definitions

  • the invention relates to a drainage element for presses Excretion of liquids from solid substances, especially for fruit presses, comprising one rod-shaped, flexible drainage core with flow paths for Deriving the squeezed liquid from the press room and a surrounding the drainage core, liquid-permeable filter cover, at least one End of the drainage element on a juice collecting plate, Pressure plate or attached to the press jacket of the press.
  • Fig. 1 shows a longitudinal section through the known Attachment of a drainage element in a fruit press.
  • a press space 2 delimited by a pressure plate 1 a known fruit press, not shown, are one A large number of drainage elements 3 are arranged.
  • a drainage element 3 consists essentially of a elastic drainage core 4, over the outside Grooves 5, as section A-A shows, the liquid during the pressing process is led out of the pressing chamber 2, and a stocking-shaped filter 6 stretched over it Solid-liquid separation.
  • Each at the ends of the Drainage element 3 are the drainage core 4 and the filter 6 fixed in a core holder 7.
  • the filter 6 will passed over an elastic cuff 8 and with an O-ring 9 fixed.
  • a disc 10 serves to support the cuff 8 against a cross pin 11 which laterally in bores of Drainage core 4 and the core holder 7 is pushed, and the axial and radial fixation of the two components 4 and 7 guaranteed to each other.
  • the core holder 7 is using a spacer 12 and a circlip 13 connected to the pressure plate 1.
  • a cam 14 of the locking ring 13 the through a slot 15 in the spacer 12 into a groove 16 of the core holder 7 engages in connection with one behind the pressure plate 1 lying collar 17 Spacer 12, the security against axial displacement forth.
  • the drainage core 4 becomes during of the pressing process before the clamping point in the Pressure plate 1 kinked sharply.
  • a disadvantage of this known type of filter and drainage core attachment especially that due to the mechanical stress on the Filter in wear zones 18 and 19 is damaged. This is done in the wear zone 18 by clamping of the filter 6 between the drainage core 4 and the cuff 8 and in the wear zone 19 due to filter abrasion as a result Pull the filter 6 over the cuff 8.
  • the sharp kinking of the drainage core 4 also its lifespan is reduced and fluid drainage partially obstructed by the grooves 5 of the drainage core 4.
  • the problem is the kinking of the circumference of the drainage core 4 located grooves 5 due to the occurring Compressive stresses, which in Fig. 1 by the sign ⁇ are symbolized.
  • the resulting reduction in cross-section the grooves 5 hinder the outflow of liquid and increases the risk of constipation depositing solids.
  • the invention is based on the object Disadvantages, especially the high filter wear to avoid a device of the type mentioned.
  • this object is achieved by a Filter attachment solved, in which the liquid permeable filter cover on the drainage core in a distance to its attachment to the Juice collecting plate, pressure plate or on the press jacket of the Is attached to a connector of the press Drainage core, comprising the part for fastening the Filter cover, the part for attachment to the Juice collecting plate, pressure plate or on the press jacket of the Press and the one between these parts
  • Spacer at least one internal juice drainage channel and the bending stiffness of this Connector is chosen so that the buckling of the Drainage element only in the area of the connector of the Drainage core between its attachment to the Juice collecting plate, pressure plate or on the press jacket of the Press and the attachment of the filter cover occur.
  • Another advantage of the invention is that by the spatial separation of the filter fixation and the Attachment of the free ends of the drainage element in the Pressure plates the components for the individual functions very much can be made compact. This results in Cost advantages especially with the elements for fastening the drainage element in the pressure plates and at Fixation of the pressure plate in the fruit press.
  • Another advantage achieved by the invention is that that on another wearing part of the known solution, namely the flexible cuff 8, can be dispensed with. Filter damage that can be avoided as Occur as a result of torn cuffs.
  • each Pressure plate 1 limited press room 2 there are one in each Pressure plate 1 limited press room 2 one not illustrated fruit press a plurality of drainage elements 3rd arranged.
  • Each drainage element 3 comprises a flexible one Drainage core 4, at the free ends 22 each flexible coupling piece 25 made of the same material is welded on and an adapter sleeve 26, an O-ring 27 and a securing spring 28 for fixing a filter 29 on the coupling piece 25.
  • the connection of the free end of the coupling piece 25 with the pressure plate 1 takes place via a clutch holder 30.
  • the pressing process takes place in one flexible, filter-free part 35 of the coupling piece 25 between the locking spring 28 for filter fixing and the Clamping point of the coupling piece 25 in the coupling holder 30.
  • the stocking-shaped filter 29 is not claimed.
  • the liquid flowing out of the press chamber 2 is in the Coupling piece 25 of external grooves 36 of the Drainage core 4 into a central drain channel 37 headed.
  • the drain channel 37 supported with three webs 18.
  • the support of the Drain channel 37 can alternatively not via one shown separate coil spring made in the Drain channel 37 is inserted.
  • the fixation of the filter 29 on the coupling piece 25 takes place using the O-ring 27, which is in a groove 39 chamfered on one side on the coupling piece 25 is located, and the clamping sleeve 26.
  • the clamping sleeve 26 is in Pushed towards the drainage core 4 over the filter 29 and by a collar 20 at the right end of the clamping sleeve 26 and the side in a groove 31 on the coupling piece 25 retractable locking spring 28 against axial displacement secured.
  • a tensile load acts on the filter 29 in In the direction of the drainage core 4, the O-ring 27 moves due to the frictional forces on the beveled groove 39 and thus increases the clamping force acting on the filter between adapter sleeve 26 and O-ring 27.
  • the coupling part 42 consists of a core holder 44, for example made of plastic, and a one-piece Coupling holder 45 with flexible kink area 46, which by Welding or gluing are firmly connected.
  • the Connection from the free end of the clutch holder 45 with a pressure plate 1 takes place with the help of a spacer 17 and a locking ring 13 as in FIG. 1 described. Sealing the joint surface between the free end of the coupling holder 45 and the spacer 17 can by a located on the clutch holder 45 Sealing lip 50 take place.
  • the fixation of a filter 29 on the core holder 44 happens with the help of an O-ring 27, which is in a groove 39 of the core holder 44, bevelled on one side, and an adapter sleeve 54.
  • the Adapter sleeve 54 over the filter 29 and the one below Slide O-ring 27 towards pressure plate 1.
  • the Fixing of the clamping sleeve 54 takes place on the core holder 44 via a snap lock.
  • Spring hooks 55 which are installed in an oblique groove 56 be clamped in the clamping sleeve 54, in designated Recesses 57 of the clamping sleeve 54.
  • the liquid flowing out of a press chamber 2 becomes via the grooves 36 of the drainage core 4 into the core holder 44 entered and passes through a centric Drain channel 51 of the coupling holder 45 outside the Press room 2.
  • the drainage element 3 shown in Fig. 4 consists of a drainage core 4, at the free ends 63 of each Coupling piece 64 is welded from the same material, a fixation of the filter 29, and a clutch holder 67.
  • the fixing of the filter 29 in the on Coupling 64 provided recess 68 takes place with two or more C-shaped tension springs 65, as the Section A-A shows.
  • the tension springs 65 are on the circumference offset openings over the filter 29 in the area of Recess 68 installed.
  • the coupling piece 64 is in Coupling holder 67 fixed with a cross pin 11.
  • FIG. 5 In contrast to those described in Figs. 2-4 Exemplary embodiments are shown in FIG. 5 shown drainage element 3 in a kink region 82 no separate coupling piece used, but the required subfunctions are determined using a modified drainage core 83 solved.
  • the drainage element 3 consists of the drainage core 83, the stocking-like filter 29, one not shown Filter fixation 65 on the drain core 83, an O-ring 86 and a locking washer 87 for the axial attachment of the Drainage core 83 in a core holder 88.
  • the axial Attachment of the drainage core 83 in the core holder 88 is carried out achieved the same means as that shown in Fig. 2nd are explained in detail.
  • the O-ring 86 which is in a groove 89 in Drainage core 83 is located.
