Definitions

  • ABSTRACT The present disclosure is directed to an apparatus for drying and steaming material which is conveyed on rolls and/or drums wherein the bearings for the fans are separated from the wall of the treatment chamber and/or the housing of the apparatus.
  • the present invention relates to an apparatus for drying and steaming material which is guided between rolls and/or drums and which is treated by a treatment medium which is applied to the material by means of fans which are associated with the treatment apparatus.
  • fans are attached directly to the housing of the various drying apparatus. Since fans, even if they are perfectly balanced, produce vibration in operation, at least some of the supporting walls of the housing of the apparatus must be very rugged to ensure the necessary reliability with respect to the fan suspension and to provide a device which is sturdy enough so that possible damage to the material being processed as a result of vibration of the apparatus during operation is substantially avoided.
  • Another disadvantage of the known fan suspensions is that in many cases the housing and/or the treatment chamber must be made of high-grade. alloyed steel or aluminum to ensure a sufficient corrosion-resistance construction when a moist atmosphere or hot steam is used asthe treatment medium. This type of construction also avoids a knockout of the attachment elements of the fans which is of particular danger if aluminum is used.
  • a precondition of the staggered drum arrangement is a relatively large overall height of the apparatus, i.e. a height of up to about several meters.
  • the apparatus thus becomes more expensive since the respective sidewall of the treatment chamber must be stabilized at least up to the bearings of the uppermost fans which are generally attached at the level of the shafts of the sieve drums of the upper row.
  • An object of the present invention is to avoid the prior art disadvantages in the conveyance of material between rolls and/or sieve drums.
  • Another object of the present invention is to provide an improved apparatus for mounting the fans which permits a thinner wall construction of the treatment chamber and/or the treatment housing.
  • a further object of the present invention is to provide an improved apparatus for drying and steaming textile materials wherein the undesirable influence of the fan vibration on the treatment chamber is substantially eliminated.
  • the entire housing may now be made of a light metal, for example, aluminum, which provides corrosion protection as well as a lighter weight device. Furthermore, the undesirable influence of the fan vibration on the treatment chamber of the apparatus is eliminated.
  • the fans may be arranged and/or supported individually or jointly in a closed frame outside the treatment chamber.
  • a possible relative displacement between the separate units will occur in operation if the treatment chamber is heated to an elevated temperature, for example, to about 250 C.
  • a special elastic seal is provided for this situation, said seal compensating for the relative displacements between the treatment chamber and the fans.
  • the seal advantageously consists of an elastic hose coupling, one end of which is connected as firmly as possible in a steam-type manner with the edge of the opening in the wall of the treatment chamber, and the other end of which is movably connected, also in a steam-type manner withthe fan shaft.
  • the latter connection is preferably effected by a sealing friction bearing.
  • any material which complies with the requirements for elasticity, steam-tightness and corrosion resistance is suitable for use as the hose coupling.
  • the aforedescribed elastic seal can compensate for relative motions in any dimension between the fans which, accordingto the invention, are supported separately and the treatment chamber of the apparatus.
  • the fans are accommodated in a bearing block.
  • FIG. 1 shows a detail and a side viewof a sieve drum steamer utilizing staggered sieve drums according to the present invention
  • FIG. 2 is a section AB according to FIG. 1, said figure showing a detail of the longitudinal section and the separate support and/or suspension of the fans according to the invention.
  • FIG. 3 is an enlarged view of detail C according toFlG. 2, said figure showing the seal according to the present invention between the treatment chamber of the apparatus and the fan support.
  • the apparatus for the-present invention comprises according to FIG. 1, a sieve drum steamer 1 containing staggered drums 2. For this reason, the overallheight D is relatively great.
  • a bearing 3 for a fan 4 issuspended separately from a'wall 5 of the treatment chamber 6 of the sieve drum steamer 1.
  • the fan bearings 3 are provided on a U-rail 7, each. of which is anchored, for example, to the floor independently of the wall 5.
  • a fan motor 19 is also-attached to a frame 18 which supports the bearings 3 of the fans 4.
  • FIG. 3 An example of the elastic seal required according to the present invention is shown in detail in FIG. 3.
  • An opening 8 in the wall 5 of the treatment chamber 6 for the fan shaft 9 is advantageously bordered by a cylindrical bushing 10.
  • This bushing is expediently welded steamtight to some or all parts 11, 1 2 and 13 of the wall 5.
  • an elastic hose coupling 14 is, according to the present invention, connected with the bush l0 and with the shaft 9.
  • the hose coupling 14 may consist of any material which complies with the require- :ments for elasticity, steam-tightness and corrosion resistance. According to the present invention, it has been found that a hose coupling of polytetrafluoroethylene which is also known under the trade name Teflon is especially suitable for this purpose.
  • An apparatus for drying and steaming materials which comprises a treatment chamber, at least one conveying means rotatably disposed in said treatment chamber, fan means associated with the conveying means for circulating the treatment medium, said fan means being provided with a fan shaft which extends into the treatment chamber, wall means having an axially disposed opening into said chamber to accommodate said fan shaft, means for supporting the fan shaft disposed independent of the walls of the treatment chamber, and an elastic sealing assembly for providing a seal between said fan shaft and said wall means of the-treatment chamber which comprises an elastic coupling fixedly attached to the walls of the treatment chamber and movably attached to the fan shaft by a friction bearing, said friction bearing being secured against turning by a pin which is fixedly attached to said bearing and the wall of the treatment chamber, thereby compensating for any relative displacement between the fan shaft and the opening in the wall means.
  • drum means are cylindrical sieve drums.
