Definitions

  • This invention relates to apparatus for chemically cleaning and drying fabrics, textiles, garments and the like and is a division of copending application Ser. No. 632,947 filed in the United States September 13, 1932 and in Germany March 5,1932.
  • Combined washing and drying machines usually consist of a perforated drum containing the articles, Vwhich rotates in a casing partially fluid is drawn off and the heated air enters through distributing tubes or through the perforations in the drum walls.
  • An object of the invention is to improve the construction and operation of rotary washing and drying machines and particularly to prevent damage to the articles being treated, and to accelerate evaporation of the washing fluid 30 and drying of the articles in the apparatus after cleaning.
  • the air is admitted into and/or ydischarged from the drum in an undivided stream.
  • the passages in the drum wall neces? sary to pass this stream are preferably quite large and are tapered and slant inwardly so that the washed articles which might otherwise enter these openings are carried -by centrifugal force and/or gravity away from the metal and walls.
  • Figs. 1 and 2 are, respectively, longitudinal and transverse sections of a machine having enlarged axially arranged inlet and outlet passages; y
  • Figs. 3 and 4 are longitudinal and transverse sections of a machine having an air inlet passage similar to that of Fig. 1 but spaced from the axis of the drum, and an outlet similar to that of my earlier application.
  • the combined ywashing and drying machine vof Figs. 1 and 2 has a closed casing I -containing 'a rotating receptacle orfdrum 2.
  • the two end walls and the perforated cylindrical wall of the drum are preferably made of sheet metal.
  • Drum 2 is provided at each end with longitudinally extending annular conical passages 3 for air. These passages which surround the axis of the drum are conically widened or flared towards the interior of the drum and are provided with radial bars 4 as shown. Such passages serve to expand the air stream adjacent the inlet and to contract the stream adjacent the outlet, thereby insuring a better distribution and circulation of air through the drum.
  • Hot air is blown by a suitable ventilator through inlet and outlet pipes 5 and through the axially arranged air chambers 6.
  • a flange 1 is arranged on'each end of the drum and each flange cooperates with a stationary close-fitting the stream of drying air.
  • the enlarged air passages 3 serve as terminals for the direct passage longed contact between the sheet metal walls ⁇ and the articles being treated, prevent damage to the latter even when the air enters the drum in a very hot state.
  • the washing machine shown in Figs. 3 and 4 has a large annular passage I3 for the stream of air in an end wall of the drum I2. This passage is widened toward the interior of the drum and is provided with radial bars I4. Passage I3 differs from passages 3 (Figs. l and 2) in that it is spaced from the axis oi the drum. This arrangement facilitates the distribution of air and the connection with pipe I5 fastened t0 the end of casing I I is simplied by the elimination of the special air chamber 6 of Fig. l.
  • Flanges I'I-I8, which span the space intermediate the drum and casing, provide an enclosed connecting conduit for direct passage of air. Flanges 2I--28 adjacent the outer periphery of the drum also prevent leakage, and wasteful circulation of the air in the channel intermediate the drum and casing.
  • the opposite end-of the drum may be provided with a passage similar to passage I3, or one of the passages 3 shown in Fig. l.
  • the other terminal for the direct passage of the air through the drum is similar to that shown in my copending application Ser. No. 632,947 previously mentioned.
  • the closed casing is partially lled with any desired type of washing fluid, such for instance as benzine, ethylene triehloride, carbon tetrachloride and the like.
  • the drying medium likewise may be of any suitable or convenient type. Thus I may use hot air or other gas for removing the solvent residue and for drying the cleaned articles. Washing uids such as benzine, which form an explosive mixture with air, can be removed by an inert gas as carbon dioxide or nitrogen.
  • Apparatus for chemically cleaning fabrics, textiles and the like comprising a casing, a rotatable perforated drum in said casing adapted to contain articles to be cleaned, said drum having at one end means for admitting gases and distributing same throughout substantially the entire interior of the drum and having at the other end means for withdrawing gases from substantially the entire interior of the drum, one of said means comprising a stationary passage in the end of said casing eccentric with, the adjacent end wall of the drum and an annular passage in the adjacent end wall of the drum communicating with said stationary passage as the drum is rotated, said annular passage being flared longitudinally toward the interior of the drum.
