Definitions
- Drainage device for presses for separating liquids from solid materials
- the invention relates to a drainage element for presses
- Pressure plate or attached to the press jacket of the press is
- 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, over the outside of which
- the core holder 7 is connected to the pressure plate 1 with the aid of a spacer bushing 12 and a locking ring 13.
- a cam 14 of the locking ring 13 which engages through a slot 15 in the spacer 12 into a groove 16 of the core holder 7, in connection with a collar 17 located behind the pressure plate 1
- Spacer 12 secures against axial displacement.
- the drainage core 4 is during the pressing process before the clamping point in the
- the sharp kinking of the drainage core 4 also reduces its lifespan and the liquid outflow through the grooves 5 of the drainage core 4 is partially hindered.
- the problem is the buckling of the grooves 5 located on the circumference of the drainage core 4 as a result of the compressive stresses which are symbolized in FIG. 1 by the symbol ⁇ .
- the resulting reduction in the cross-section of the grooves 5 hinders the outflow of liquid and increases the risk of clogging by solid deposits.
- the invention has for its object to avoid the disadvantages mentioned, especially the high filter wear, by a device of the type mentioned.
- this object is achieved by a filter attachment, in which the liquid-permeable filter sleeve is attached to the drainage core at a distance from its attachment to the juice collecting plate, pressure plate or to the press jacket of the press, a connecting piece of the drainage core, comprising the part for attaching the filter sleeve, the part for attachment to the juice collecting plate, pressure plate or to the press jacket of the press and those located between these parts
- Spacer has at least one internal juice drainage channel and in which the bending stiffness of this connecting piece is selected so that the drainage element kinks only in the area of the connecting piece of the drainage core between its attachment to the
- the liquid outflow in the kink region of the drainage element does not take place through external channels on the drainage core, but through one or more central channels.
- the cross-sectional reductions described in FIG. 1 on the grooves 5 of the drainage core 4 can be avoided.
- the kink on the drainage element can be shaped in such a way that only slight bending stresses occur and thus the service life of the drainage core or a coupling element can be significantly increased compared to the known solution.
- Another advantage of the invention is that the spatial separation of the filter fixation and the attachment of the free ends of the drainage element in the pressure plates means that the components for the individual functions can be made very compact. This results in
- Another advantage achieved by the invention is that there is no need for a further wearing part of the known solution, namely the flexible cuff 8. This also prevents filter damage that occurs as a result of torn cuffs.
- FIG. 1 shows a section through a known fastening of a drainage element to the pressure plate of a fruit press
- FIG. 2 shows a section through an attachment of a drainage element according to the invention to the pressure plate of a fruit press
- FIG. 3 shows a section through an attachment of another drainage element according to the invention to the pressure plate of a fruit press
- FIG. 4 shows a section through an attachment of a further drainage element according to the invention to the pressure plate of a fruit press
- FIG. 5 shows a section through an attachment of a further drainage element according to the invention to the pressure plate of a fruit press.
- a plurality of drainage elements 3 are arranged in a press space 2 of a fruit press, not shown, each delimited by a pressure plate 1.
- Each drainage element 3 comprises a flexible drainage core 4, one at each of its free ends 22 flexible coupling piece 25 made of the same material is welded on, as well as an adapter sleeve 26, an O-ring 27 and a securing spring 28 for fixing a filter 29 on the coupling piece 25.
- the free end of the coupling piece 25 is connected to the pressure plate 1 via a coupling holder 30.
- the securing against axial displacement from the free end of the coupling piece 25 in the coupling holder 30 is achieved with a locking spring 21 which is pushed laterally into the coupling holder 30 through a slot 22 and engages in a groove 23 at the end of the coupling piece 25.
- An O-ring 24 is used to seal the joining surface between the free end of the coupling piece 25 and the coupling holder 30.
- a sharp kinking of the drainage element 3 during the pressing process takes place according to the invention in a flexible, filter-free part 35 of the coupling piece 25 between the securing 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 pressing chamber 2 is in the coupling piece 25 by external grooves 36 of the
- Drainage core 4 passed into a central drain channel 37.
- the drain channel 37 is supported with three webs 18. The support of the
- Drain channel 37 can alternatively also take place via a separate spiral spring, not shown, which is inserted into the drain channel 37.
- the filter 29 is fixed on the coupling piece 25 with the aid of the O-ring 27, which is located in a groove 39 on the coupling piece 25, and the clamping sleeve 26.
- the clamping sleeve 26 is pushed in the direction of the drain core 4 over the filter 29 and secured against axial displacement by a collar 20 at the right end of the clamping sleeve 26 and the locking spring 28 which can be inserted laterally into a groove 31 on the coupling piece 25. If a tensile load acts on the filter 29 in the direction of the drainage core 4, the O-ring 27 moves up due to the frictional forces on the beveled groove 39 and thus increases the clamping force acting on the filter between the clamping sleeve 26 and the O-ring 27.
- a drainage core 4 is detachably connected to a coupling part 42 by a cross pin 43.
- 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 are firmly connected to one another by welding or gluing.
- the connection from the free end of the clutch holder 45 to a pressure plate 1 is carried out with the aid of a spacer 17 and a locking ring 13 as already described in FIG. 1.
- the sealing surface between the free end of the coupling holder 45 and the spacer bush 17 can be sealed by a sealing lip 50 located on the coupling holder 45.
- a filter 29 is fixed on the core holder 44 with the aid of an O-ring 27, which is located in a groove 39 of the core holder 44 which is chamfered on one side, and an adapter sleeve 54.
- the adapter sleeve 54 is placed over the filter 29 and the underlying O. -Ring 27 pushed onto pressure plate 1.
- the clamping sleeve 54 is fixed on the core holder 44 by means of a snap lock.
- two spring hooks 55 located on the core holder 44 which are clamped during assembly in an oblique groove 56 ' in the clamping sleeve 54, snap into recesses 57 provided in the clamping sleeve 54.
- the fixing of the clamping sleeve 54 on the core holder 44 can also be done by a bayonet lock or not shown a screw connection can be produced.
- the clamping sleeve. 54 is rotated relative to the core holder 44, the spring hooks 55 being pressed out of the cutouts 57 via bevels 58. The clamping sleeve 54 can then be pulled down from the core holder 44.
- the liquid flowing out of a press chamber 2 is passed through the grooves 36 of the drainage core 4 into the core holder 44 and passes through a central one
- the drainage element 3 shown in FIG. 4 consists of a drainage core 4, at the free ends 63 of which a coupling piece 64 made of the same material is welded, a fixation of the filter 29, and a coupling holder 67.
- the filter 29 is fixed in place on the coupling piece 64 provided recess 68 is made with two or more C-shaped tension springs 65, as shown by section AA.
- the tension springs 65 are mounted with openings offset on the circumference above the filter 29 in the region of the recess 68.
- the coupling piece 64 is fixed in the coupling holder 67 with a cross pin 11.
- the drainage element 3 is fastened in a pressure plate 1 via the coupling holder 67 with a spacer bush 17 and a locking ring 13 as already described under FIG. 1.
- the drainage element 3 consists of the drainage core 83, the stocking-like filter 29, a filter fixation 65 (not shown in more detail) on the drainage core 83, an O-ring 86 and a locking washer 87 for the axial fastening of the drainage core 83 in a core holder 88.
- the axial fastening of the drainage core 83 in the core holder 88 is achieved by the same means, which are explained in detail in FIG. 2.
- the O-ring 86 which is located in a groove 89 in the drainage core 83, is used to seal the joining surface.
- the fixation 65 of the filter 29 in a recess 68 provided for this purpose on the drainage core 83 can be done by tying the filter 29 with a thread, with a flexible band with Velcro fastener or the like.
- the drainage element 83 is fastened in a pressure plate 1 via the core holder 88 with a spacer bush 17 and a locking ring 13 as already described under FIG. 1.
- the liquid to be discharged from a press chamber 2 is guided through the grooves 36 of the drainage core 83 and in the kink region 82 of the drainage element 3 through a central bore 37 in the drainage core 83.
