Definitions

  • the invention relates to a dryer, in particular a tumble dryer, according to the The preamble of claim 1, 4 and 11, respectively.
  • Dryers in particular tumble dryers for commercial use (Laundries, etc.), have a rotating drivable drum.
  • the drum points At opposite ends or opposite end portions on races. With The drum rests on wheels on the races.
  • At least one impeller is drivable, so that hereby the drum frictionally in a rotational movement about its longitudinal central axis is displaceable.
  • the longitudinal center axis of the drum forms at the same time their Axis of rotation.
  • the invention has the object, a dryer, In particular, tumble dryer, to create a simple and light has mountable and removable drum. At the same time, the dryer should be low-wear.
  • a dryer for solving this problem has the features of claim 1.
  • the inventive compound of the races by struts leads to a stable Drum cage, which allows a precise concentricity of the drum.
  • the drum cage forms a static-carrying part of the drum, which is a reliable and accurate Storage of the jacket plate of the drum allows, whereby the jacket sheet itself no or does not have to have any significant bearing properties.
  • This can in particular, formed from a plurality of jacket plate parts jacket plate with the Drum cage can be easily connected without having to connect the sheath sheet metal parts is required with each other.
  • the preferably welded to the races struts are according to a preferred Design of the device provided with a profiled cross-section.
  • the struts are box-shaped or hollow profile-like, where it is sufficient the hollow profile is not completely closed, but for example open on one side train. This design of the struts contributes in particular in connection with the Welding the same with the races to form a stable, in itself carrying drum cage.
  • the shrouds are of several individual Sheath sheet parts formed, which are connected by clamping with the drum cage.
  • the thus out of the drum cage and several directly not in connection Standing drum formed sheet metal parts drum can be easily assembled.
  • individual sheath sheet metal parts can be replaced.
  • the at least partially clamping connection the cladding panel parts with the drum cage allows relative movements of the cladding panel parts to the drum cage, for example, by a temperature-induced expansion the shell sheet metal parts this or their corresponding edges due to by the Clamping frictional and / or non-positive connection takes place relative to Drum cage, in particular the struts of the same, can move.
  • the transverse edges or adjoining edge regions of the shell sheet metal parts on the struts continuous clamped, preferably by terminal strips.
  • the attachment of the Cross edges of the shroud parts is to pay special attention to it is sufficient, only the transverse edges of the shell sheet metal parts clamped to the bars of To attach drum cage.
  • the longitudinal edges of the Mantelblechteile can in conventional Be screwed to the races, where it is sufficient, only relatively few screws to use.
  • the clamping bars are preferably simultaneously as projecting ribs in the interior of the Drum formed.
  • the terminal strips have a double function, that is, There are no additional components required for the terminal strips.

  • This non-contact seal is as good as not subject to wear and does not brake the drum against the direction of rotation. As a result, the force to drive the drum over known dryer with friction grinding ring seals reduced.
  • the non-contact sealing of the drum with respect to the housing takes place in the area each race on an opening having an end face of the drum.
  • drums with a stable drum cage has the respective race over a high running accuracy, whereby with small gap widths a reliable and always non-contact seal can be realized.
  • the preferably machining (Turning, grinding or the like) takes place after the races through the struts are connected by welding in particular. Then at the same time at the Machining eliminates any distortion of the races due to welding.
  • statically supporting, stable training of Drum cage and the machining of the races can be a very high Accuracy of even large drums achieve the non - contact seals for Housing also allows for relatively small gap widths.
  • the non-contact sealing of the drum with respect to the stationary housing takes place in the region of the respective opening on one or both opposite End faces of the drum through annular end-side areas of the races opposite to a closely spaced adjacent end wall of the housing.
  • the existing sealing gap can be reduced by at least one gap-reducing ring-like coating, in particular sealing coating. This one is designed that he does not the respective end face of the race during the rotation of the drum touched, and leaves only a sealing gap to the relevant end face of the race, the is relatively narrow.
