Definitions

  • the invention relates to a device for the removal of liquid from strand-like fibrous, matted materials, in particular from sugar cane bagasse with a high moisture content, to which the materials are supplied in a loosened form and which has co-operating press rolls with the liquid collecting channels associated therewith.
  • the above-mentioned preferred application of the device for sugar cane bagasse concerns the drainage of the bagasse, both of sugar cane diffusion bagasse and of demarked sugar cane bagasse, as e.g. is used for further processing in the paper industry.
  • the invention has for its object to provide a device of the type mentioned in such a way that the structural outlay and the wear of the device parts are reduced and thus the maintenance costs and also the required drive energy are considerably reduced and, in addition, a uniform fluid withdrawal from the materials is ensured.
  • the above-mentioned device is designed such that two hollow press rolls cooperating with low pressure or medium pressure in a range between 0.5 and 50 kg / cm 2 are provided and can be driven in rotation in a support frame with central axes running in a common horizontal plane are maintained that the feed nip between the press rolls in the area of their ends is sealed by lateral boundary walls and a feed chute for the materials to be squeezed, which extends at least up to the lateral boundary walls, projects above the feed nip and surrounds the cross section of the feed nip, and that the peripheral walls of the two press rolls are perforated and equipped with radially projecting drivers in the form of knobs or strips.
  • the press rolls mentioned can be designed as relatively thin-walled sheet metal rolls, depending on the press pressure provided, even if they have a relatively large diameter in order to achieve a sufficient residence time for the material between the rolls.
  • a favorable pressing of the material between the press rolls takes place in that both rolls are perforated and the maximum paths of the liquid squeezed out of the material correspond to half the gap width between the press rolls.
  • the liquid can flow relatively quickly into the interior of the rollers, the perforated rollers ensuring that the fluid flows out of the interior of the roller into the liquid collecting channels just as quickly.
  • So-called low-pressure press rolls are known (DE-OS 30 21 311), but they are always pre-dewatering rolls that either interact with a conveyor level designed as a screen for the material strand that has not yet been loosened or as a pair of rollers at the end of the conveyor level of the crop strand are arranged and exert a pressure on them before loosening.
  • the rollers are arranged one above the other, an upper smooth roller interacting with a lower perforated roller.
  • only a small amount of pre-dewatering can be achieved solely in view of the thickness caused by the strand of material and the matting of the material.
  • the outflow of the liquid is only possible in one direction, namely to the conveying plane designed as a sieve or to the lower roller. In view of the long distances caused by this for a large part of the liquid, it is not possible to drain off to the required extent during the pressing process, so that the pressed liquid is taken up again by the strand emerging from the pressing zone.
  • the present invention is concerned with avoiding the great effort previously required for the high-pressure press rolls. Surprisingly, this is actually possible with the above-mentioned design of the device according to the invention.
  • the drivers of both press rollers so that they the holes in the walls of the Rollers with a radial clearance, but completely cover in plan view. This ensures that the holes in the walls of the rolls remain free of clogging and allow the liquid to flow quickly into the interior of the press rolls or out of the press rolls into the collecting troughs.
  • the openings in the walls of the press rolls can be designed as bores or slots or also differently shaped recesses.
  • a particularly advantageous embodiment and mode of operation is obtained if the drivers laterally tightly enclose the holes in the walls of the press rolls except for an area pointing against the direction of rotation of the rolls.
  • an inflow of the squeezed liquid is achieved in the holes on the pressure-relieved side of the radially projecting and penetrating drivers.
  • the outflow of the pressed liquid is promoted and at the same time the risk of clogging of the holes in the walls of the press rolls is additionally reduced.
  • the gap as the side walls for sealing the feed nip of the press rolls
  • Cover flange rings held on the end face of the respective roller and rotating with the roller are provided. This results in a relatively simple lateral covering of the feed nip, so that the material to be pressed off cannot emerge laterally from the rollers when it is drawn into the press nip.
  • the contour of the feed nip of the press rollers is adapted to the walls held in the supporting frame and covering the nip space above the roller axes near the roller ends and on the outer circumference of the rollers with the walls sealingly cooperating rings are held. If the rings do not come into contact with the walls, a labyrinth seal will still result, which will surely prevent the material to be pressed out. If one also wants to achieve a lateral liquid seal of the feed gap, the aforementioned walls can be arranged displaceably in the longitudinal direction of the gap space and can be held in contact with the rings held on the rollers under the action of springs.
  • the rings or the walls can be coated with corresponding abrasion-resistant sealing materials in order to ensure a liquid-tight seal.
  • the rings mentioned also have the effect that, when materials with a large proportion of liquid are pressed off, the liquid which has already been pressed off in the area of the feed nip runs against the roller wall movement over the outer wall surface of the press rolls and onto the latter Paths to the collection troughs provided below the press rolls.
  • the static pressure of the material column prevailing in the feed shaft can be used to pre-press the material.
  • the feed chute has perforated walls as well as circumferential collecting troughs arranged at a distance above one another in a liquid-tight manner and connected to the outside of the walls. In this way, it becomes possible for the liquid squeezed out due to the static pressure of the column to emerge from the feed shaft and be discharged before the material reaches the nip between the press rolls.
  • the feed chute is equipped with a fill level controller which is equipped with a control device for driving the press rolls and / or one Feeder for the loosened material is connected.
  • the outflow of the squeezed liquid from the press rolls is favored if they are equipped with guide plates arranged on the inside of the wall and each pointing at an incline in the direction of rotation.
  • the liquid emerging from the interior of the press rolls through the openings in the walls is fed to the collecting troughs usually arranged below the rolls.
  • the press rolls can be kept movable relative to one another in order to set the respective same press pressure be, the axis of at least one press roll being supported in an adjustable abutment.
  • a hydraulic piston-cylinder arrangement can be provided as the abutment and adjusting device, which is connected on the one hand to the axis of one roller held in a fixed bearing and on the other hand to the other axis of the other roller held in a floating bearing.
  • pre-dewatering rolls are arranged at a distance above the press rolls and the feed chute is offset in the direction transverse to the longitudinal axis of the press rolls and with one section Larger cross-section extends to the inlet nip of the pre-dewatering rolls and extends with its section reduced in cross-section from the outlet nip of the pre-dewatering rolls to the entry nip of the press rolls. It is expedient if the pre-dewatering rolls have a smaller diameter than the press rolls, but have the same design as the press rolls and are equipped with liquid collecting channels and side walls to cover their feed gap.
  • the drawing shows exemplary embodiments of the invention in a schematic representation in connection with the drainage of sugar cane diffusion bagasse.
  • this is equipped with striking or tearing arms 4a, which engage in a movement of the loosening roller 4 in the direction of the arrow shown in the crop strand 3 and loosen the crop, so that it is fed to the conveyor 5 in the loosened state, which
  • it can be designed as a scratch conveyor and can also run parallel to the longitudinal axis of the loosening roller 4, with its end of the task pivoted by 90 °, and can thus be made considerably narrower than the material strand 3.

  • the drivers 16 enclose the bores 15 and 15a except for an area pointing against the direction of rotation of the press rolls, which forms the gap 17 shown, through which the liquid can get into the bore 15 and 15a.
  • the inlet gap 17 for the liquid lies on the side of the drivers 16 facing away from the pressure, so that the inflow of the liquid to the bores 15 and 15a is thereby favored.
  • FIG. 9a to 9c show two other forms of training of the drivers, which are particularly easy to manufacture.
  • two different versions of the drivers are shown, which are designated 16a and 16b.
  • FIG. 9a shows in a sectional view through the peripheral wall 10 of the press roll 9 the arrangement of the drivers 16a and 16b, the top view of which can be seen from FIG. 9b.
