Definitions

  • the invention relates to a device for removing 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 have cooperating press rolls with the liquid collecting channels assigned to them.
  • 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.
  • Low-pressure press rolls are known (DE-OS 30 21 311), which cooperate to achieve a pre-dewatering with a conveying plane designed as a sieve for the not yet loosened material strand. Also for main drainage, instead of sugar cane mills, low-pressure press rolls have been provided in such a way that they are arranged as a pair of rolls at the end of the conveying plane of the strand of material and exert a pressing pressure which is effective longer than in sugar cane mills before loosening. The rollers are arranged one above the other, an upper smooth roller interacting with a lower perforated roller.
  • the invention has for its object to provide a device of the type mentioned for pressing or the pre-dewatering of a loosened stream of material so that the structural effort for pressing compared to the previously required sugar cane mills and the drive energy required for pressing are significantly reduced and, in addition to previous low-pressure press rolls, an improved and uniform removal of liquid from the materials is ensured both in the preliminary dewatering and in the pressing.
  • the device mentioned above is designed in such a way that two hollow press rolls cooperating with low pressure or medium pressure in a range between 0.5 and 50 kg / cm 2 are rotatably held in a supporting frame with central axes running in a common horizontal plane are that the feed gap between the press rolls in the area of their ends is sealed by lateral boundary walls and a feed chute is provided for the materials to be pressed at least as far as the lateral boundary walls, projecting beyond the feed gap and enclosing the cross section of the feed gap, and that the peripheral walls of the two Press rolls are perforated and are equipped with radially projecting drivers in the form of knobs or strips.
  • the present invention is concerned with subjecting the already loosened material flow to effective dewatering with little effort.
  • the press rolls of the device designed according to the invention can be designed as relatively thin-walled sheet metal rolls as a result of the low working pressure as a function of the press pressure provided, even if they have a relatively large diameter in order to achieve a sufficient residence time of 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 away relatively quickly into the interior of the rolls, the perforated rolls ensuring that the liquid flows out of the inside of the roll into the liquid collection channels just as quickly.
  • 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 rollers remain free of clogging and allow the liquid to quickly drain off into the interior of the press rollers or from the press rollers into the collecting troughs.
  • the openings in the walls of the press rolls can be designed as bores or slots or in other ways figurated recesses.
  • a particularly advantageous embodiment and mode of operation results if the drivers tightly enclose the holes in the walls of the press rolls, except for an area pointing counter to the direction of rotation of the rolls. In this way, an inflow of the squeezed-out liquid into the holes on the pressure-relieved side of the radially protruding portion and drivers which penetrate into the material flow is achieved. This promotes the outflow of the squeezed liquid and at the same time additionally reduces the risk of clogging of the holes in the walls of the press rolls.
  • 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 which are usually arranged below the rolls.
  • the side walls for sealing the feed nip of the press rolls are provided with flange rings which cover the nip and are held on the end face of the respective roll and face outward and rotate with the roll.
  • the contour of the feed nip of the press rollers is adapted to the walls held in the supporting frame and covering the gap 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 you also want to achieve a lateral liquid seal of the feed gap, so 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 pressing off materials with a large proportion of liquid, the liquid which has already been squeezed out in the area of the feed nip runs counter to the roll movement over the outer wall surface of the press rolls and in this way reaches the collecting 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 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 set down in the direction transverse to the longitudinal axis of the press rolls is formed and extends with a section of larger cross-section to the entry nip of the pre-dewatering rolls and extends with its section reduced in section from the exit nip of the pre-dewatering rolls to the entry nip of the press rolls.
  • 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 device designed according to the invention can also be used with great advantage only for the preliminary dewatering of the loosened material strand.
  • the press rolls are arranged as pre-dewatering rolls above a sugar cane mill and between the press rolls and the sugar cane mill there is a shaft section with a smaller cross-section than the feed shaft to the press rolls for feeding the pre-dewatered material to the sugar cane mill is.
  • the pre-dewatering rollers arranged above the sugar cane mill are connected to the drive of the sugar cane mill. This results in a particularly simple construction of the entire drainage device.
  • the press rolls can also have a construction which differs from the design described above.
  • This is advantageously characterized in that the press rolls are double-walled and the outer perforated circumferential walls enclose an inner all-round closed roller body at a radial distance and axially outstanding on both sides, that the space between the outer peripheral wall and the peripheral wall of the inner roller body by radially and parallel to the axis of rotation extending webs is divided into chambers and the outer peripheral wall is connected to end walls which have free through openings at least at the level of the chambers.
  • the inner baffles that would otherwise be necessary are eliminated.
  • the pre between the inner roller body and the outer peripheral wall seen chambers lead to less deposits than is the case with rollers with inner guide plates.
  • the further advantage is achieved that the cleaning of the rolls is simplified and increased dimensional stability is achieved.
  • the webs provided between the outer perforated peripheral wall and the inner roller body only extend over the axial length of the inner roller body and the end walls connected to the outer peripheral wall are designed as ring flanges which only partially extend over the height of the chambers.
  • 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.
