Definitions

  • the invention relates to a press for squeezing liquid-containing substances, namely agricultural and chemical products with a container which has a filling and emptying opening and that in the interior of the container, a press membrane made of flexible or elastic material is arranged, the interior into a pressure medium and press room divided.
  • a wide variety of embodiments of membrane presses are known, for example tubular membranes, flat membranes that are clamped perpendicular to the axis of rotation, sack-shaped membranes, the fastening plane of which is parallel to the axis of rotation, and the like.
  • These presses which operate pneumatically or hydraulically, have prevailed above all because they can be gently pressed out of the material to be pressed, the actual pressing process being carried out discontinuously, i.e. the press is filled with the material to be pressed, this is pressed out completely and the residues are finally discharged.
  • the container To loosen the material to be pressed, the container must rotate during the loosening phase in these known presses.
  • These discontinuous presses have the major disadvantage that the performance, i.e. the throughput of material to be pressed is insufficient, and large-capacity tank presses have been built in order to improve the size of the performance. However, this involves a particularly high expenditure of material, which makes the manufacture of such presses considerably more expensive
  • the invention has for its object to design a press of the type mentioned in such a way that taking advantage of a membrane press enables continuous operation in the pressing process.
  • the invention has the essential advantage that an efficient pressing of an agricultural or chemical product is possible, the size of which can be considerably reduced compared to the conventional discontinuous presses of this type. Another significant advantage is that different pressure levels can be set up within the press, so that an exact adaptation of the press to the particular material to be pressed is also possible without difficulty. Due to the faster pressing, while avoiding loosening devices, there is even less turbidity, and the risk of oxidation is also reduced. In addition, there are only short juice paths through the mash, because the pressure layer can be kept low during continuous throughput within the press.
  • the first embodiment of such a press shown in FIGS. 1 to 4 has a machine frame 1 on which a fixed container 2 is mounted, a hopper 3 being arranged on one side of this container 2.
  • a screw conveyor 4 mounted on the machine frame 1, which has a screw shaft 6 with spirally extending screw blades 5 arranged thereon.
  • the screw conveyor 4 is driven, for example, by a motor 7 with a drive 8.
  • a conically enlarging 5-screw tube 11 is provided in the area of the hopper 3, i.e. of the filling chamber 9 with the filling opening 10.
  • the individual screw blades 5 are enlarged at their edges with the aid of fastening elements 12, a membrane 13 being clamped in a pressure-tight manner at this fastening point.
  • the membrane 13 consists of a strip, preferably of a rubber-elastic material, but a flexible plastic material can also be used here, which must then sag as far as the worm shaft 6 or must extend to the edge of the container 2, this strip spiraling between adjacent ones Screw blades 5 is wound up to the end of the screw conveyor 4.
  • the discharge opening 14 is located at the discharge end of the conveyor screw 4.
  • the membrane 2 divides the container 2 into a pressure medium chamber 15 and a press chamber 16, in which the material to be pressed is located.
  • a worm shaft journal 17 is provided with a corresponding connection.
  • the worm shaft 6 can also be divided several times, so that at least two pressure spaces 15 are created in order to work with different pressure zones.
  • the function of the continuously operating press is as follows.
  • the press is fed with the substance to be pressed out via the hopper 3, this hopper 3 being correspondingly large and thus constituting a storage space for continuous processing.
  • Other types of loading are also possible by conveying directly into the pressing space 16, e.g. with the help of a pump or a screw.
  • This hopper 3 is located at the screw entrance, whereby the auger 4 is started and the material to be pressed is moved a certain distance, e.g. half, one or one and a half revolutions depending on how often the PreBgut is to be pressurized and loosened up during transport.
  • the membrane 13 is expediently placed on the worm shaft 6, in particular to prevent damage.
  • This position is shown in Figure 3.
  • the screw conveyor 4 stops so that pressure medium can flow between the screw conveyor 4 and the membrane 13 and pressure is exerted on the product (FIG. 2).
  • the press remains under pressure for a shorter or longer period. After releasing the pressure, the screw conveyor 4 starts moving again until it stops.
  • the pressing work can take place in one pass or one pass only serves as pre-pressing. It is also possible to set up several pressure levels in one screw pass.
  • FIG. 4 shows the cross section through such a press, the container 2 being composed of two container halves 18, 19, which have laterally offset eyes 20 and a simple connection of the two halves can be achieved by pushing rods through.
  • the container halves 1B, 19 themselves can have a sieve shape, so that the squeezed liquid can flow off directly.
  • This type of construction of the container shell 2 results in simple assembly and also cleaning options.
  • a further fixed, closed drum jacket can be arranged around this container 2.
  • the two-part is most advantageous, but a one-piece, closed container with an access opening can also be used, or the container can be divided into a larger number of segments.
  • FIGS. 5 and 6 show the arrangement of the start and end of the membrane strip 13, a web 21 being attached to the worm shaft 6 and continuing in an angled flange 22, the end of the membrane 13 being attached to the flange by means of a pressure strip 23 22 pressure fluid tight is attached.
  • the latter is reinforced in such a way that bulging laterally into the filling space 9 or the emptying opening 14 is prevented.
  • FIGS. 7 and 8 show this end region of the membrane, various layers 25 being placed on top of one another and fastened.
  • FIGS. 9 to 11 show different possibilities for fastening the edge 26 of the press membrane 13, a reinforcement 25 also being present here.
  • the edge 26 of the membrane is against the edge of the screw blade 5 on the one hand with the aid of a pressure bar 27 and on the other hand screwed with the help of the fastening elements 12.
  • the screw wing 5 is correspondingly extended and the edges 26 of the press membrane 13 are fastened within the screw wing 5 with the aid of the pressure strips 27.
  • the pressure bars of the screw vanes increasing fastening elements 12 are in the embodiment of Figure 11 27, respectively b zw on the front sides of the screw blade 5.
  • FIGS. 12 to 15 show a further embodiment of such a press, such an embodiment being useful if such a press has to be built with a higher output, which leads to greater overall lengths.
  • the shaft 6 must be made with a larger diameter in order to prevent bending.
  • the worm blades 5 are fastened directly to the shaft 6, for example by a pressure bar 27 being attached to it as a foot and this foot 27 being screwed to the shaft 6, the diaphragm 13 being clamped in using a reinforcement 25 .
  • the ends of such a strip-shaped membrane 13 are each fastened to the shaft 6 with pressure strips 27.
  • the worm blades 5 are welded to the shaft 6.
  • a so-called spiral screw 29 is used here as the screw conveyor, which is fastened to the ends of the screw, specifically to the flanges 30.
  • the membrane 13 'then lies within this helical screw, and it can then curve outwards between the individual wings of this screw 29, as is indicated in FIG. 18.
  • the attachment of this helical screw 29 is also shown enlarged in FIGS. 19 and 20, the attachment to the flanges 30 using end parts 31.
  • a tubular membrane 13 ' is drawn over the screw shaft 6, which is connected to the discharge opening 14 with the aid of a the flange on the strins side is attached in a pressure-tight manner and on the filling funnel 3 with the aid of a clamping ring 34, with the outside of the diaphragm 13 'screw segments 5' being attached.
  • These screw segments 5 'can consist of the same material as the membrane 13' and can be vulcanized, glued or releasably attached, for example.
  • the membrane 13 'together with the screw segments 5' can also be produced in one piece, for example by casting.
  • FIG. 23 an embodiment of such a press is indicated in FIG. 23, in which a hose 33 is arranged between the screw blades 5 of the screw, this hose 33 extending over the entire length of the screw 4 or of the container casing.
  • the hose With the help of a pressure medium, the hose can be inflated in such a way that it bulges outward against the container wall 2 and thus the pre-effect is brought about.
