Definitions
- the invention relates to a drainage element for presses for separating liquids from solid substances, in particular fruit presses, consisting of a rod-shaped, flexible core with flow paths for discharging the pressed-out liquid from the press chamber and a liquid-permeable filter sleeve surrounding the core, at least one end of the drainage element via a Dra 'inageschtake at a Saftsammeiplatte or fixed to the press cover.
- a larger number of such drainage elements is arranged, for example, in the press chamber of a fruit press between the movable and the fixed pressure plate.
- the flexible drainage elements deform during the pressing process or when the movable pressure plate is closed.
- the squeezed juice penetrates the filter cover of the drain nageelements and is led out of the pressing space along the flow paths of the rod-shaped core and directed into a juice collection.
- both ends or, in the case of one-sided fastening, only one end of the drainage element are detachably fastened to the pressure or juice collecting plates, which on the one hand delimit the press chamber and on the other hand delimit the juice collecting chamber.
- the flow paths for the juice are formed by longitudinal grooves, which are arranged on the outer circumference of the core and open into the juice collection space via the drainage lock.
- the pressed juices are heavily contaminated with fine solids or trub particles.
- small lumps of trub can form, which are supported in their flow movement by the bending movements of the flexible drainage cores.
- this movement support is missing and solid trub plugs are formed, which clog the longitudinal grooves of the drainage core.
- Juice drainage can be severely hampered, resulting in increased yield and performance losses.
- the removal of the blockages is often very tedious and time-consuming because the drainage elements have to be removed and the workflow of the press is interrupted. In addition, increased chemical cleaning is required.
- the invention has for its object to avoid the disadvantages mentioned and blockages in the area Prevent drainage locks to improve the function and performance of the press.
- this object is achieved in that the flow paths of the drainage element are enlarged in the region of the drain lock.
- the flow paths of the drainage element are advantageously formed by longitudinal grooves which are arranged on the outer circumference of the core and which are enlarged in the region of the drainage lock.
- a particularly simple measure for enlarging the longitudinal grooves which can also be applied to juice presses already delivered, consists in removing every second web of the drainage core formed between the longitudinal grooves in the region of the drainage lock.
- the longitudinal grooves in the region of the drainage lock are flared.
- Another way of increasing the flow paths is to increase the depth of the longitudinal grooves in the area of the drainage lock.
- the advantages achieved with the invention are in particular that, due to the expansion of the flow channels in the area of the rigid drainage lock, the inflowing ones Turbid parts are no longer inhibited in their flow movement and are immediately washed out into the juice chamber.
- the dwell time in the extended flow channels is too short for a fast growth of the sediment particles. Clogging of the flow channels is thus successfully prevented and the performance of the press is increased.
- the interval between the periodic cleaning work of the press can also be increased
- Fig. 2 is an enlarged view of one end of the drainage element
- FIG. 3 shows a section through the drainage element along the line III-III in FIG. 2
- a plurality of drainage elements 2 are arranged in a press space 1 of a fruit press, not shown in detail.
- the free ends of the drainage element 2 are each releasably attached via a drainage lock 3 to juice collecting plates 4, which on the one hand delimit the pressing chamber 1 and on the other hand juice collecting chambers 5.
- juice collecting plates 4 which on the one hand delimit the pressing chamber 1 and on the other hand juice collecting chambers 5.
- Each drainage element 2 consists of a rod-shaped, flexible core 6, which is surrounded by a stocking-like filter cover 7.
- the core 6 has a plurality of longitudinal grooves 8 distributed around the circumference, which serve as flow paths for the pressed juice.
- the filter sleeve 7 is fastened to the core 6 by a plug-in part 9 which penetrates the juice collecting plate 4 with a sleeve 10.
- the plug-in part 9, the sleeve 10 and the juice collecting plate 4 together form the drainage lock 3, which enables the drainage element 2 to be detachably fastened to the juice collecting plate 4.
- the sleeve 10, which projects into the juice collecting space 5, has bores 11 for the exit of the juice, which is guided through the drainage lock 3 via the longitudinal grooves 3 of the drainage element 3.
- Crosspieces 12 are formed between the longitudinal grooves 8 of the core 6, by means of which the longitudinal grooves 8 are separated from one another. Every second web 12 is removed at the ends of the core 6. This creates new longitudinal grooves 13 which are widened by approximately two to three times compared to the longitudinal grooves 8. The length of the longitudinal grooves 13 corresponds approximately to the length of the area in which the drainage element 2 is immobile due to its mounting in the rigid drainage lock 3.
- the longitudinal grooves 10 in the region of the drainage lock can be flared or the groove depth increased as a further measure for pre-enlarging the flow paths.
