Definitions

  • the intended concentration of the inertial mass on a relatively narrow area below the drum axis means that the mass resembles, like a boat keel, the most favorable point for stabilizing the drum against changes in position. place. In other words, you can work with relatively less mass with the same effect.
  • the principle used according to the invention is in contrast to conventional concepts, in which the broadest possible distribution of the inert mass was considered necessary or expedient.
  • the development of the invention according to claim 2 is advantageous in that the inert mass only needs to be connected to the machine at the installation site, so that it is easier to handle during transport and installation. If necessary, a mass package can be put together on the spot from steel plates which are available practically everywhere, so that the transport of inert mass, which accounts for a very considerable part of the total weight, is eliminated.
  • the design of the housing mounting specified in claim 3 has proven to be particularly suitable for absorbing the vibrations which are not balanced by the inert mass.
  • the arrangement of the bearing points provided for claims 4 and 5 is particularly favorable for the stability of the bearing and the absorption of the bearing forces. Since the width of the machines does not exceed the housing diameter as a result of the concentration of the inert mass according to the invention, these support points are freely available.
  • FIG. 1 shows a schematic front view of an industrial washing machine
  • Figure 2 is a side view, with parts broken away, and
  • Figure 3 shows a bearing in detail.
  • the machine shown in the drawings comprises a drum 11 mounted in a cylindrical housing 10 about a horizontal axis for receiving the textiles to be cleaned.
  • a door 12 for loading the drum 11 is provided on the front end of the housing 10.
  • the drum 11 is provided with an axle journal 14 which is mounted in an outer bearing 13 of the housing 10, which carries a pulley driven by an electric motor 16 via a belt 15.
  • a basket 17 is provided for receiving a mass package 18.
  • the basket 17 forms an approximately cuboid-shaped receiving space that is continuous over the entire axial length of the housing 10, the height and width of which correspond to approximately one fifth of the housing diameter.
  • the basket 17 consists of square profiles, which are welded to the housing 10 (shown at 28 in Figure 3) ring flanges via struts 19 extending tangentially to the housing 10.
  • the mass package 18 is preferably made up of individual steel plates which are assembled at the installation site and rigidly connected to the basket 17.
  • the housing 10 is supported in a frame 26 at four bearing points 21 (shown in more detail in FIG. 3), which are located at the four corners of an imaginary horizontal plane corresponding in depth to the axial length of the housing 10.
  • This plane can be the meridian plane containing the drum axis.
  • the connecting line between the center of the drum and the bearing point forms an angle of approximately 30 ° with the horizontal.
  • the angle ⁇ can be between 0 and 45 °.
  • the actual bearing element consists of a spherical elastomer cushion 22 with parallel bases, on each of which a bearing plate 23, 24 is vulcanized.
  • the lower bearing plate 23 is welded to the upper end of a vertical support 25 of the frame 26.
  • the upper bearing plate 24 is welded to the lower leg of a support strip 27 which extends over the entire length of the housing 10 and is connected to the ring flanges 28 surrounding the housing 10.
  • the right end of the support bar 27 and the support (25) carrying it have broken away.
  • a further bearing point can be provided on each side of the drum, which has a middle point of the support bar 27 via a bearing element (22, 23, 24) with the upper end of a further middle support (15) of the frame 26 combines.
  • Such an even more stable storage can be useful for larger drum volumes or if perchlorethylene is used as the solvent, which has a much higher density than hydrocarbon solution (KWL).
  • the support strip 27 has a box profile, at least in the area of the bearing point 21, on which a tab 29 which runs obliquely downwards attaches.
  • An air-filled shock absorber 31, which runs obliquely to the vertical, is arranged between the free end of the tab 29 and a further tab 30 welded to the support 25.
  • the existing at the axial ends of the drum housing 10 a total of four pairs of inclined shock absorbers 31 absorb movements of the housing 10 together with the drum 11 in both the vertical and horizontal directions.
  • the shock absorbers 31 have a natural frequency of approximately 3.3 Hz, so that resonance phenomena only occur when passing through the lower, safe spin speed range.
  • the frame 26 is designed separately from an outer machine frame 20.
  • the concentration of the inertial mass 18 in a narrow area below the drum housing 10 results in an overall small machine width. Therefore, the additional devices provided in conventional machines above the drum housing 10 (air dryer including cooling and heating devices, etc.) can be arranged laterally next to the drum housing 10 within the machine frame 20 in the machine according to the invention without increasing the overall space requirement.
  • Such a laterally arranged additional device is indicated at 32 in FIG. LIST OF REFERENCE NUMBERS

Abstract

L'invention concerne un dispositif de centrifugation destiné à l'essorage de textiles. Ce dispositif présente un tambour monté pivotant sur un axe sensiblement horizontal et logé dans un boîtier (10). Un panier (17), situé perpendiculairement sous l'axe de tambour, est destiné à recevoir une masse (18) dans une zone dont la largeur ne correspond qu'à une partie du diamètre du tambour. Le boîtier (10) est doté de deux barres d'appui (27) qui supportent le boîtier (10) et le tambour en au moins quatre points d'appui (21) à l'aide de coussinets élastomère (22), de telle façon qu'ils puissent vibrer dans un cadre fixe (25, 26).
