Definitions

  • a guide housing for, conducting or transporting air which is charged or contaminated with impurities, such as dust or fibers.
  • the inventive guide housing possesses a housing body member having an approximately cylindrical or spiral-shaped cross-section.
  • This housing body member further incorporates an inlet opening, a discharge opening as well as a discharge connecting piece or stud which communicates with the discharge opening and is tangentially directed with respect to the housing body member.
  • the housing body member is equipped with means for generating a spin or spiral flow within the housing body member.
  • the discharge connecting piece or stud extends opposite to the direction of deflection of the spinflow generating means in order to produce an aerodynamic reduction of the cross-section.
  • the effective flow cross-sectional area of the discharge connecting piece or stud is reduced to a fraction of the actual cross-sectional area thereof, to thereby enable discharge of air and fiber accumulations even larger than the effective flow cross-sectional area.
  • the present invention relates to an improved guide housing for, transporting air charged or contaminated with impurities, especially dust or fibers.
  • Another, more specific object of the present invention relates to an improved apparatus for, effectively transporting air contaminated with impurities, such as dust 01' fibers, in such a way that there is no tendency for the air flow channels to become clogged.
  • Yet a further significant object of the present invention relates to an improved apparatus for, conducting away air charged with impurities, such as dust and fibers, in an extremely efficient, economical and reliable manner, with little likelihood of clogging of the apparatus and downtime of the associated pneumatic cleaning installation.
  • the inventive guide housing for air charged or contaminated With dust or fibers incorporates a housing body member possessing an approximately cylindrical or spiral-shaped cross-section.

  • the guide housing can be also used for the uniform blowing out of air charged with fibers over a very Wide, narrow discharge stud. This is of importance for the pneumatic cleaning of textile machines having large surfaces which are to be cleaned, since it is then possible not only to use clean air but also air charged with fibers for the blowing operation without clogging of the discharge cross-section.
  • the aspect of the invention contemplates providing an effective flow cross-sectional area of the discharge spout or connecting piece which is only a fraction of the actual cross-sectional area of such connecting piece, to thereby enable discharge of air and fiber accumulations even larger than the effective flow cross-sectional area.

This is of particular importance as will become apparent more fully hereinafter.
  • the clean air stud or connecting piece 16 will not come into coincidence with any of the studs or connecting pieces 23 or 25 due to the imaginary rotation previously described above.

  • the tip or apex of the filter 20 is formed by an air permeable hood or cover member 25'.
  • Guide members or devices 30' are arranged within the housing portion 12'. These guide members 30' impart a spin or twist to the inflowing air charged with fiber and dust; this spin or twist being in the clockwise direction when viewed in the direction of movement of the air. Moreover, such spin or twist of the air can be already imparted in the infeed stud or connecting piece 14.
  • the clean air stud 16 piercingly extends through the central region of a substantially spiral-shaped guide housing 24' and is directly connected with the clean air side of the filter 20.

  • the ventilator or fan 19 sucks air, for instance out of the spinning room, through the inlet stud or connecting piece 23.
  • This air is charged with contaminants such as fiber and dust and has imparted to it by means of the air infeed spiral 14 a spin or twist which is in the counterclockwise direction of FIG. 2.
  • a translational movement is superimposed upon the spin or twisting movement in the direction of the axis 24" towards the stud or connecting piece 26.
  • the fibers can periodically accumulate in large quantities, for instance if the filters of pneumatic cleaning installations at spinning machines are cleaned.
  • the largest portion of the air in the separator 10 passes through the cylindrical filter member 20 and arrives via the stud or connecting piece 16 at a suitable non-illustrated air conditioning installation, for instance.
  • the fibers entrained by the air are held back by the cylindrical filter member 20, further rotate along a spiral-shaped path mixed with a small quantity of transport air and arrive at the guide housing 24.
  • the cylindrical filter member 20 has imparted to it a selfcleaning action due to the rotation of the fibers and the air.
  • the air and the fibers appearing in the stud or connecting piece 26 are conveyed by the fan or ventilator 21 and transported into a suitable apparatus which finally removes the fibers from the air.
  • the mode of operation of the separator 10 depicted in 'FIGS. 3 and 4 is essentially similar to that previously described in connection with the separator construction 10 of FIGS. 1 and 2.
  • the difference between these separators resides primarily in the manner of producing the spin or twist of the air flow which, in the case of the second embodiment of FIGS. 3 and 4, is produced by the previously discussed means 30.
  • FIG. illustrates a sectional view of the inventive guide housing, the section being taken at right angles or perpendicular to the axis 24" of the spiral-shaped guide housing 24 or 24'.

  • Reference numeral 39 designates the center of the spiral, in other words, the point of piercing of the axis 24" of the housing body member 31 through the section plane. In the case of a spiral which is not defined mathematically, the center 39 should be located at the center of gravity of the spiral.
  • the nose member 37 is formed by the intersection at a point of the wall 40 of the stud 38 which is located closer to the center 39 of the spiral and the inner casing or jacket portion 35. This nose member 37, however, can possess an infinitely large radius.
  • the separation or partition location between the inner and outer jacket portions 35 and 33, respectively, should be defined by the point or location 36 situated diametrically opposite the nose member 37.
  • the inner and the outer jacket portions 35 and 33, respectively, of the spiral can be portions of a logarithmic or Archimedes spiral. In such cases the center 39 coincides with the geometric center or pole of the spiral.
  • the outer and inner jacket portions 33 and 35 can be also composed of circular arcs of different "radii or from a single circular arc or can approximate a polygon.
  • the air which should leave a spiral through a stud or connecting piece, rotates within the spiral in counterclockwise direction in the arrangement depicted in FIG. 5. In so doing, the air flows at least along the outer jacket portion 33 and arrives finally in an undisturbed path in the stud or connecting piece 38. With this direction of rotation there is provided a 6 frontal flow against the nose member 37 which thus determines the amount of air which flows out through the stud or connecting piece 38.
  • the air rotates in clockwise direction in the spiral depicted in FIG. 5. Consequently, the air flows at least along the inner jacket portion 35 and finally towards the nose member 37. Thereafter, there occurs an abrupt deflection of this air about this nose member 37, opposite to the twist or spin direction prevailing in the spiral.
  • FIG. 6 there is depicted a further possibility for producing a spin or twist in a spiral and a further possibility of use of the inventive guide housing.
  • a substantially spiral-shaped guide housing which is laterally limited or bounded by end plates or sheets 52.
  • Reference numeral 56 designates the axis which extends in lengthwise direction of the guide housing 50 through the center of the spiral.
  • this guide housing 50 possesses a tangentially exiting discharge stud or connecting piece 55, at the end of which there is provided a relatively long and relatively narrow discharge slit or slot 54.
  • a narrow stud or connecting piece 58 merges at least approximately tangentially and preferably perpendicular to the axis 56 with the guide housing 50.
  • this stud or connecting piece 58 can be also arranged to connect with the guide housing '50 at an inclination with respect to the lengthwise axis 156. As will be apparent by referring to FIGS. 6 and 7, the stud or connecting piece 58 is arranged centrally symmetric to the stud with respect to the lengthwise axis 56.
