Definitions

  • the invention relates to the technical field of tobacco fiberization.
  • it relates to the technical field of shredded tobacco material production by defibration and, more specifically, the invention is to shred a tobacco rib material to produce a product having particularly advantageous properties which can ultimately be used to make smoking articles.
  • the defibration of tobacco materials has been found to be advantageous, because from the starting material, for example, a rib material, a very high quality product can be produced, the sensorial and its structure after the quality of cut tobacco hardly lagging.
  • the pressure defibration is very efficient, allows a high material yield and provides unique products.
  • a generic tobacco fiberizing apparatus which has a heatable pressure chamber, which in turn has a tobacco material inlet on the low pressure side, a relaxation gap outlet on the pressure side and a shaft-mounted screw conveyor for conveying the tobacco material from the inlet to the outlet.
  • the auger shaft is mounted on the inlet side, runs until just before the outlet and is cantilevered there in the chamber.
  • the screw conveyor is centered relatively well with the aid of the product flow in the pressure chamber.
  • the free-standing end of the auger shaft inside the pressure chamber housing so that, for example, when starting the system inlet grooves in the housing and on the shaft increased wear.
  • the conveyor worm shaft extends further behind the outlet in the device and is again stored there by means of an abutment.
  • the screw conveyor shaft is centered or immobilized in the area of the outlet by being supported on both sides of the pressure chamber.
  • This multiple bearing has the advantage that it ensures the stability of the shaft position in the outlet area, in all operating conditions; This reduces the wear and the life and reliability are increased.
  • the mentioned counter-bearing can be fixed according to the invention with respect to the pressure chamber, and thereby also the centering of the shaft by the counter-bearing against the pressure chamber and in particular with respect to the stationary arranged at the pressure chamber outlet is effective, i. exactly in the most important place.
  • the counter-bearing is arranged on a discharge head, which adjoins the pressure chamber and is attached at its outlet end.
  • the invention is further characterized in that the gap outlet is limited by a first outlet part, which is attached to the pressure chamber or on the outlet head, and a second outlet part which is non-rotatably mounted on the shaft.
  • This embodiment in turn results in great advantages, and it can also be regarded as a separate invention or as a separate purpose of the invention. Namely, the devices according to the prior art have two separate axes, one for the screw conveyor and one for a part of the gap outlet, because these two elements are not on one sitting together wave. Due to ever-present manufacturing tolerances but these two axes are not really aligned with each other and this leads to small gap distances to increased wear of the tool, so the outlet parts.
  • the second outlet part is non-rotatably seated on the auger shaft, the centered orientation of the second outlet part (tool part) is by definition (even at very small gap distances), and therefore can be also realize smaller gap distances.
  • the second outlet part can be fixed to adjust the gap size at different axial positions of the shaft. It can also be chosen an embodiment in which the second outlet part for adjusting the gap size is axially displaceable and fixed by displacement means mounted on the shaft.
  • the first outlet part may form an outer part of the gap outlet, while the second outlet part forms an inner part of the gap outlet.
  • the gap of the gap outlet is an annular gap, especially a cone gap, wherein in particular the outer part has an inner cone and the inner part has a corresponding outer cone. Outer part and inner part move advantageously relative to each other, of course, moves in the above-proposed embodiment, of course, the second outlet part; because it rotates with the shaft.
  • gap sizes will be in a range of 0.01 mm to 2 mm, in particular in the range of 0.1 mm to 0.5 mm. It is possible to make the gap walls so that they have roughening or profiling, in particular groove or funnelrillenprofilleiteren, which are preferably arranged transversely to the gap wall movement direction and in particular have a depth of up to 3 mm.
  • speeds of 0 to 600 min -1 can be achieved if drive and storage or counter bearing of the device (the auger shaft) are designed accordingly.
  • the tobacco material is introduced on the low pressure side of a pressure chamber and relaxed on the pressure side of the chamber at a gap outlet and discharged, the tobacco material by means of a Both end portions shaft-mounted screw conveyor is conveyed from the inlet to the outlet, and wherein the screw conveyor is operated in a speed range of up to 600 min -1 .
  • the speed range of the operating speed can essentially begin at one of the following values: 50 min -1 , 100 min -1 , 150 min -1 , 200 min -1 , 250 min -1 . It can terminate substantially at one of the following values further 300 min -1, 350 min -1, 450 min -1 500 min -1, 550 min -1. Intermediate values are possible, the selection depends on the particular device present and the desired input and output parameters.
  • a screw conveyor 1 which sits on the shaft 19, accommodated in a tube 3, which serves as a pressure chamber.
  • the screw conveyor 1 and the shaft 19 may be components of a single piece, which differ only by their function; but they can also be formed or composed of several pieces or parts.
  • the tool 7 comprises an inner cone 11 (outer part or first outlet part), ie a hollow cone.
  • the second outlet part or the inner part is formed by the cone 9, and this cone 9 is rotatably mounted on the shaft 19. Between the tapered wall of the cone 9 and the inner wall of the inner cone 11 creates a gap outlet.
  • the inner cone 11 of the tool 7 is mounted in a discharge head 13, which has the same as the inlet side arranged gear housing 15 bearings 17, which serve as an abutment according to the present invention.
  • the bearings of the gear housing 15 carry the reference numeral 16.
  • the counter-bearing 17 supports the common shaft 19, which carries the screw conveyor 1 and the cone 9.
  • the tool 7 has an adjustable gap, which is, however, fixed before the start of production, such as by a fixation of the cone 9 at a certain axial point of the shaft 19 by conventional means.
  • an adjustable gap is advantageous if the operating parameters are known and retracted precisely and a change in the gap width during production is not necessary.
  • the cone 9 to be stored on the shaft 19 displaceable fixable, in such a way that the gap width can be selectively varied during production.
  • a sliding fit and a hydraulic cylinder force application can be selected, either against a second hydraulic cylinder or against a spring bearing.
  • the rotational speed in devices of the prior art is limited to low values in the range of about 50 min -1.
  • With the multi-bearing shaft of the device according to the invention can be rotational speeds up to 300 min -1 , in particular even reach up to 600 min -1 , without being able to determine increased wear.
  • inventive device can be expected with a significant increase in material throughput, as in Figure 2 is shown.
  • Figure 2 the curves of the material throughput compared to the necessary pressure for systems with multi-bearing shaft (dashed) and with one-sided bearing shaft according to the prior art (solid) to see.
