Definitions

  • the invention relates to a device for squeezing liquid from the liquid-containing substances, in particular for juicing fruit mash, with an endless screen press belt, which is guided in the device like a serpentine, the substance being applied to the side of the screen press belt facing the press rollers, and between the deflecting rollers mounted in a frame of the device are provided for the screen press belt in the frame of the device.
  • Devices for squeezing liquids out of substances are known in which the substance, e.g. Fruit mash is passed between sieve press belts over drainage drums, the sieve press belts wrapping around the drainage drums over part of their circumference.
  • Such devices are known for example from AT-PS 363 872 or EP-B-13 549.
  • the invention has for its object to provide a device of the type mentioned, in particular a belt press for juicing fruit mash, with which even when using a single, endlessly rotating screen press belt an efficient juicing of fruit mash or, in general, an efficient squeezing out of liquid from substances containing liquid is possible.
  • this object is achieved in that at least one of the deflection rolls provided between the press rolls is mounted on supports which are pivotably mounted in the device.
  • the pressing force of the deflection roller (s) under the action of the tension of the screen press belt can be exerted on one of the adjacent press rolls, in particular in the area at the end of the wrapping of the press roll by the screen press belt on the the desired additional pressure on the material to be pressed (fruit mash).
  • the resultant goes from the forces exerted by the screen press belt on the deflection roller either through the pivot axis of the carriers (neutral position) or the resultant has a distance from the pivot axis, so that a moment pressing the deflection roller against the adjacent press roller.
  • the axes of the press rolls and the deflecting rolls are aligned horizontally and arranged essentially in one plane.
  • a device according to the invention has proven itself in practice, in which it is provided that the press rolls have a decreasing diameter in the direction of the movement of the screen press belt.
  • a preferred embodiment of the device according to the invention is that the carrier of the deflecting roller is mounted on bearings which are adjustable in the frame.
  • the contact pressure ie the pressure with which the at least one deflecting roller under the action of the tension of the screen press belt on the screen press belt on the associated with it Press roller is present, can be adjusted to the desired value by changing the position of the bearings and thereby the position of the above-mentioned resultant to the pivot axis of the carrier of the deflection roller is selected accordingly.
  • This makes it possible to adapt the additional pressure exerted on the fabric by the screen press belt under the action of the deflecting roller to the properties or the degree of dewatering (juicing) of the fabric (fruit mash).
  • the deflection roller is mounted on its supports at a distance from a plane passing through the pivot axis of the supports.
  • the carriers have, for example, one leg which projects vertically from them and on which the deflecting roller is mounted.
  • the deflecting roller is additionally loaded under the action of the tension of the screen press belt on the press roll and thus increases the contact pressure of the screen press belt on the press roll, which is arranged on the side which the axis of the carrier from the going through the pivot axis of the carrier Level is adjacent.
  • the adjustment of the carrier for the deflecting roller and thus the selection of the contact pressure of the same to the press roller assigned to it is particularly simple if, according to a proposal of the invention, it is provided that the carriers of the deflecting roller are mounted on bearing supports which are essentially perpendicular to the Axes of the press rolls extending parts of the frame of the device can be clamped.
  • the belt filter press has a frame 1, in which a mash container 2 with mash feed is mounted at the top.
  • press rolls 3, 3 ', 3' 'and 3' '' are mounted around horizontally aligned axes of rotation, which in the exemplary embodiment shown are essentially in a horizontal plane.
  • the press rolls 3, 3 ', 3' 'and 3' '' are mounted in bearing brackets 20 which are fastened to a main support 21 of the frame 1 which extends essentially horizontally.
  • a drive roller 5 for a screen press belt 22 is provided on the far left in FIG. 1. This drive roller 5 is driven by a motor, not shown.
  • the screen press belt 22 is guided in a serpentine manner between the press rolls 3 and the deflection rolls 4.
  • a band sensor 6, which detects the lateral alignment of the screen press belt 22, is assigned to the run back of the screen press belt 22 below the press rolls 3 and deflection rolls 4. Furthermore, this strand of the screen press belt 22 is assigned a belt straightening roller 7, which is adjustably mounted in the frame 1 perpendicular to the plane of the drawing in FIG. 1.
  • adjustment devices designed as pneumatically actuatable actuators are provided for adjusting the strip straightening roller.
  • the screen press belt 22 runs back to the mashing task 2 around a belt tensioning device, which is also actuated by pneumatic bellows 8.
  • Each press roll 3 is also assigned a stripping device 9, which is assigned to the section moving upward - the screen press belt 22 runs counterclockwise in FIG. 1 (arrow 34).
  • the stripping device 9 strips off the press rolls 3 from the press rolls 3, if necessary, of any adhering, dewatered or juiced substance, and returns the material to the rotating screen press belt 22.
  • the liquid squeezed out of the substance to be dewatered, in the case of fruit mash, the fruit juice, is collected by guide devices and supplied to juice collecting trays 11.
  • the deflection rollers 4 are mounted on supports 30 so as to be rotatable about axes 31.
  • the supports 30 are on horizontal main supports 21 of the frame 1 of the pressing device, which are perpendicular to the axes 31, around horizontal, i.e. to the axes 31 of the guide roller 4 parallel axes 32 pivotally mounted in bearing supports 33.
  • the axis 31 of the deflecting roller 4 is offset from the plane 35 going through the axis 32 of the carrier 30 and is arranged so offset that the axis 31 is arranged on the side opposite to the plane 35 which goes through the pivot axis 32 of the carrier 30 which, based on the running direction of the screen press belt 22 (arrow 34 in FIG. 2), faces the press roll 3 arranged in front of the deflecting roll 4.
  • the bearing brackets 33 of the brackets 30 carrying the deflection roller 4 are clamped to the horizontally running main brackets 21 of the frame 1 of the device by means of tensioning screws 36. It is thus possible to change the position of the carriers 30, which carry the deflecting roller 4, between adjacent press rollers 3 and thus also the size of the moment and thus the contact pressure with which the deflecting roller 4 is to be pressed via the screen press belt 22 onto the press roller 3 arranged in front of it, to the respectively desired level. A position is also possible in which the deflecting roller 4 does not press on either of the two pressing rollers 3 adjacent to it.
  • the deflecting roller 4 is between the press rollers 3 and 3 'or its supports 30, more precisely their bearing supports 33, are set on part 21 of the frame 1 in such a way that the deflecting roller 4 is based on the tape running direction (arrow 34 in Fig. 2) - press roller lying in front of it - exerts less pressure than the deflection roller 4 'between the press rollers 3' and 3 ''.
  • the carrier 30 for the deflecting rollers 4 the pressure with which the endless screen press belt 22 passes through to the press rollers 3 in the region of the end of the wrapping of the press rollers 3 the screen press belt 22 can be adjusted to the desired value, for example depending on the properties of the substance from which liquid is to be squeezed.
  • the invention can be represented as follows, for example: In a juicer press for juicing fruit mash, an endless screen press belt 22 is guided in a serpentine manner between press rolls 3 and deflection rolls 4 arranged between press rolls 3.
  • the deflection rollers 4 are on carrier 30 and Bearing bracket 33 is pivotally mounted in frame 1 of the device about pivot axes 32.
  • the bearing supports 33 of the supports 30 for the deflecting rollers 4 are adjustable so that the distance of the resultant from the forces exerted by the screen press belt 22 on the deflecting roller 4 to the pivot axis 32 of the supports 30 can be changed.
  • the magnitude of the moment by which the deflecting roller 4 is pressed onto one or the other of the adjacent press rollers 3 can be adjusted to the most favorable value in order to adjust the contact pressure between the screen press belt 22 and the press roller 3 at the end of a wrap area Screen press belt 22 and press roll 3 to increase.
