Definitions

  • the machines which are the most generally used for this purpose provide for the movement of the liquid medium and of the articles to be washed when hanging freely in the said liquid medium through a mechanical stirring, for instance by means of beaters or the like stirring means.
  • This stirring has also been produced through hydraulic means, for instance through a circulat ing pump, a syphon or the like means.
  • the mass of liquid carrying the washing and scouring products is set in motion and held in the presence of the products or of articles to 'be treated in a manner such that said treatment is performed exclusively through the mechanical stresses and through the action of the treating products whereby the liquid medium is polluted gradually as the treatment pro gresses; consequently, at the end of the operation and whatever known means are applied, the treated or washed products remain always immersed at the end of the operation in the aqueous medium which is polluted to a maximum.
  • said cellular mass is particularly well adapted for retaining the impurities carried by the maing water, treating products and heat can only lead to a detrimental result as concerns the grade of treatment and conversely this grade can be improved only 'by giving up any attempt to reach such an economy in water, treating products and heat.
  • This invention relates to an apparatus for carrying out anovel method according to which the actual washing step is produced in a medium which is at the start of an aqueous nature and is then totally or partly transformed into a mass having a cellular structure with a high-consistency, which is neither froth nor an emulsion but a special state of the liqiud matter, the specific weight of which is less than that of the original liquid mass whereby the original stirring is automatically reduced while said cellular mass assumes in combination with the stirring movement a comparatively low but constant rising movement.
  • This special state is produced through the introduction into the aqueous medium in which the articles to be washed are immersed of a gasiform fluid such as; air under very particular conditions disclosed hereinafter. As a matter of fact, it may be easily proved that the mere blowing of air is inoperative, when provided under any pressure, at any point of the vat and through any means.
  • the gasiform fluid is introduced into the aqueous medium through the rotary member which produces therein the desired mechanical stirring and the streams of gasiform fluid are terial or article to be washed.
  • this rising component in the cellular mass brings automatically said im-- purities to the surface of the mixture in the vat. It is therefore. advisable to introduce into the washing procedure a further step which consists in removing periodically the upper fraction of the cellular mass and conse.
  • This novel method is adapted to be applied systematically in a perfectly controlled manner through the agency of special machines which form also the object of this invention.
  • This washing machine includes in combination with and inside a vat at least one rotary member, for instance of the pulsator type, said arrangement being such as will produce within the liquid mass areas submitted to a reduced pression followed by higher pressure areas while it alsoallows the introduction of a' gasiform fluid, genenerally air, in the form of a plurality of streams leading. to said areas submitted to a reduced pressure as provided by, the. suction produced through said areas.
  • the air insuitably outlined peripheral recesses which are directly connected with the bore in said hollow shaft whereby the rotation of said pulsator member produces inside the liquid mass successive areas submitted to low pressure and to high pressure; the air streams drawn into the machine revolve together with the pulsator member and enter always the liquid massthrough the low pressure areas.
  • Said special pulsator member may obviously be executed in substantially different forms which allow its suitable adaptation for various purposes.
  • said rotary pulsator member may be-located' at different pointsof the vat and, for certain applications; it is possible to set inside the vat a plurality of such rotary members.
  • Figure 1 is a diagrammatic radial cross-section of this" improved washing machine.
  • Figure 2 is a plan view, partly sectional, of the pressure reducing pulsator member.
  • Figure 3'- is a cross-section through line II-IIII' of Figure 2.
  • the washing machine according to the invention in cludes thus a vat 1 provided with a double conical concave bottom 2-3 the upper wall 2 of which isperforated' at 4.
  • a false perforated bottom 5 may in certain cases be provided above said frusto-conical bottom 2'--3.
  • Through the central portion of the latter is provided an opening in which the rotary pulsator member is fitted.
  • the latter is constituted for instance by a hollow shaft 6 to which is secured the actual pulsator member 7 which latter is optionally capped by a screen 8.
  • Saidpulsator member is adapted to be driven into rotation at a high speed by an electric motor 9 through the agency of a pulley 10 keyed to the axis of the motorof abelt 11 and of a pulley 12 secured either directly to the hollow shaft.
  • the hollow shaft 6 communicates with an air intake 14 extending for instance above the upper edge of the vat 1.
  • This air intake may be provided with a throughout-adjusting and closing valve 15, the flap or cover of which may be perforated or otherwise designed so as to provide apassage for the pipe 16 feeding for instance a heating. fluid.
  • the actual pulsator member 7 is constituted as shown in Figures 2 and 3 by two parallel flanges 1-7 and 18 rigidly interconnected by radial or approximately radial ribs 19 defining recesses 20 facing outwardly.
  • the bottom of each recess 20 opens into at least one tangential or approximately tangential passageway 21 opening in: its turn into the hollow shaft 6; Opening into each recess 20 on the downstream side of the opening end of'each channel 21 may be provided a further channel 22- passing through the lower flange 18.
  • Said suitably outlined passageway 22 terminates with a lip 23 projecting underneath the flange 18.
  • the ribs 19 are bounded by arcuatesurfaces having forwardly convex outlines meeting near the outer periphery of the pulsator.
  • this pulsator member provides for the systematic. change in the state of the liquid medium as disclosed hereinabove. Said state is perfectly reversible so that it may be. produced, and destroyed almost instantaneously, by opening or closingthe air intake 14.
  • This procedure consists in introducing into the vat 1 of the machine the desired amount of water, washing products and articles to be washed.
  • the motor 9 is then started while the air intake 14 is transiently closed.
  • a washing machine comprising a vat adapted to be filled with an aqueous medium and to contain the articles to be washed, a pulsator member having a vertical axis, a hollow shaft coaxially rigid with the. pulsator member, a bent air intake pipe, means through which. said intake pipe communicates with the bore in said shaft, an ex tension for said air intake pipe extending up to a point. above the uppermost level of the aqueous medium in the vat and opening into the atmosphere, an; adjustable closing member for the upper end of said extension, a pipe adapted to convey a heating fluid in heat exchanging re.-' lationship with said closing.
