Definitions

  • the invention relates to an arrangement for sealing the inlet of a rotating Drum for the treatment of tobacco with a closing end of the drum End wall which has an inlet opening which is concentric with the axis of rotation of the drum Has tobacco, and one protruding through the inlet opening into the drum stationary feed line, the outer peripheral surface of which at least in the region of Inlet opening concentric with the axis of rotation of the drum and with the edge of the Inlet opening of the rotating end wall forms an annular gap.
  • tobacco Before processing, tobacco becomes end products such as cigarettes, cigarillos, pillars and such rod-shaped tobacco articles are usually pretreated or conditioned. To it can be used in one or more treatment stages in a rotating drum with a Treatment medium brought into contact or exposed to certain environmental influences become.
  • the tobacco is usually fed into the drum by a stationary one Feeding device such as a pipe or a slide.
  • a stationary one Feeding device such as a pipe or a slide.
  • the invention has for its object a further sealing arrangement of the beginning Specify described type with improved properties.
  • This object is achieved according to the invention in that on the peripheral surface of the feed line a stuffing box seal on the outside of the end wall of the drum is arranged with an annular sealing body sealing the annular gap.
  • This Seal reliably seals the drum from the environment and is for setting and Maintenance work easily accessible. It does not interfere with the tobacco movement inside the Drum, and at most small amounts of the sealing material get into the Drum. The seal is protected from exposure to pieces of tobacco.
  • the sealing body of the gland seal is made made of felt.
  • the selection of felt as a sealing material has the advantage that it is inexpensive and tolerated by the tobacco industry.
  • the sealing body is impregnated with a sealing compound, being as Sealant preferably a silicone oil comes into question. Soaking the sealing ring with silicone oil increases its sealing effect and its service life.
  • the further sub-claims 5 to 8 contain features of a preferred embodiment of the Sealing arrangement according to the invention. This training also increases their sealing Effect and enables service-friendly optimal setting of the on the Sealing ring acting pressure. This allows the most favorable operating conditions for the seal can be set.
  • the sealing arrangement proposed according to the invention offers the advantages that in the event of a seal defect or wear caused by wear, only slight Amounts of the sealing material get into the tobacco and that this sealing material is tolerable in the unavoidable small amounts for the tobacco industry in tobacco.
  • felt is inexpensive as a sealing material.
  • the sealing arrangement is easy to maintain and enables quick and easy replacement of the Sealing material. No tobacco can deposit on the seal and it is in front of the mechanical impact of tobacco protected. With simple and inexpensive means a very effective and advantageous seal of a rotating treatment drum realized for tobacco.
  • drum 1 shows a drum 1 for the treatment of tobacco. That drum has an inlet side 2 and an outlet side 3. It is known in the drawing not shown rotatably arranged.
  • the outlet side 3 of the drum 1 lies in a stationary housing 4, in the not shown Devices for conveying or for further treatment of the drum 1 leaving tobacco are provided.
  • the inlet side 2 of the drum 1 has a radial end wall 6 with a central concentric Inlet opening 7 through which a stationary feed line 8 for introduction of tobacco protrudes into the drum.
  • a funnel 9 or one opens into the feed line 8 other loading device for feeding tobacco.
  • the boundary between the rotating end wall 6 of the drum 1 and the stationary feed line 8 is with a Sealed arrangement 11 sealed.
  • the drum arrangement described can be used, for example, for loosening and conditioning serve from tobacco leaves removed in layers from bales. Such drums but are also used to treat cut tobacco used in these drums heated, moistened, dried, mixed, mixed with additives and in any other way is treated.
  • the sealing arrangement 11 is shown in detail in FIG.
  • the drum 1 has one cylindrical outer wall 12 and is closed on the input side by the end wall 6.
  • a cylindrical section 13 of the feed line 8 projects into the drum 1 the end wall 6 provided inlet opening 7 of the drum 1 largely to the outer diameter of the cylindrical portion 13 of the feed line 8 is a Opening reducing adapter ring 14 inserted into the inlet opening 7 and with the End wall 6 connected.
  • the seal assembly 11 is as Stuffing box seal with a sealing body 17, preferably made of felt, which is impregnated with an impregnating compound, preferably silicone oil.
  • the sealing body 17 is formed as a ring that the cylindrical portion 13 in the boundary region between the End wall of the drum and the cylindrical portion 13 surrounds a ring. He is in one Retaining and pressure ring 18 bordered him axially and radially in its intended Holds position in front of the annular gap 16.
  • the holding and pressure ring 18 has an approximately L-shaped Cross section with a radial annular surface acting on an end face of the sealing body 24 and a cylindrical bearing against the outer peripheral surface of the sealing body Ring surface 26.
  • the holding and pressure ring 18 is against the with adjustable pressure the annular gap 16 sealing body 17 pressed.
  • An adjustment device is used for this 19 with an adjusting screw 21 provided in a on the feed line 8 Ring flange 22 is mounted and acts axially on the holding and pressure ring 18. At the extent Several such adjustment devices 19 can be provided, so that the whole Extent a uniform pressure can be set on the sealing body 17.
  • this seal assembly 11 sits on the outside of the drum are easy Wise maintenance and renewal work possible. With the adjustment of the pressure the adjusting device 19 can be easily worn on the wear of the material Sealing body 17 are reacted so that always optimal sealing conditions are obtained stay.
  • the selection of felt as a sealing material is acceptable for the tobacco industry, because any parts of the sealing material that get into the tobacco Do not permanently affect the quality of the tobacco. However, by arrangement of the sealing body 17 outside the drum in front of the narrow annular gap 16, that at most small amounts of the sealing material get into the tobacco can.
  • drum 1 as a release drum for layers removed from tobacco bales Used tobacco leaves, some of which still clump together, is due to the arrangement the seal assembly 11 outside the drum ensures that the seal against the impact of larger tobacco packages is protected. That has positive things Influence on the life of the seal.
