Definitions

  • the present invention relates to a device for the continuous cleaning of material webs, in particular paper or fabric webs, in which the material web is continuously movable past air suction means, the air suction means extending over the entire width of the material web and with an air suction channel in Flow connection.
  • sheet-like semifinished products e.g. made of paper, plastic, fabrics or even precious metals
  • sheet-like semifinished products must be carefully cleaned of dust, dirt and fluff before they are further processed, in order to avoid, for example, misprints in the printing shop, contamination of treatment baths in the finishing shop, etc. . to avoid.
  • the dedusting devices used to date have not been able to meet the increasing requirements for the degree of dedusting. If, for example, a fabric web with a feed of 60m / min. is moved over a suction slot of 20 mm width, then the exposure time of the air flow is about 0.02 sec. This is rarely enough for effective cleaning and is among other things absolutely useless for flocked webs.
  • the object of the invention is therefore to provide a device of the aforementioned type which, despite the high feed rate of the web, ensures a long exposure time of the air flow and thus optimal cleaning.
  • the air suction means which are in flow connection with the air suction duct are diffusers, of which a plurality are arranged one behind the other in the direction of movement of the material web and a plurality are arranged next to one another and open out in a common plane parallel to the material web, wherein a plurality of bars serving to support the web, arranged in a lattice-like manner, extend obliquely in the direction of movement of the web toward the center of the web to produce a spreading effect in the mouth plane of the diffusers, and to form a very large one flat suction mouth plane, three diffusers are arranged symmetrically one behind the other and open out in a funnel shape in the mouth plane, the two outer diffusers having a deflection of approximately 90 °.
  • the bars arranged in a grid-like manner are supported on a frame with respect to their inclination and if the frame outside the bars has two, extending over the entire width of the device, superior to the support plane of the bars for the web, guiding the Remove the rulers that serve the web.
  • the rods can be designed as scrapers or brushes on the support side of the web.
  • the material web is continuously and horizontally moved past air suction means 2, 3, 4 in a known manner, which extend over the entire width of the material web and over an air Air intake duct 1 is in flow connection with an air intake unit 10 (high-pressure fan).
  • air intake unit 10 high-pressure fan
  • the air intake diffusers 2, 3 and 4 of which a plurality are arranged one behind the other in the direction of movement 5 'of the web 5 and a plurality are arranged side by side, these opening out in a common plane 7 parallel to the web.
  • three diffusers 2, 3 and 4 are advantageously arranged one behind the other symmetrically and open into of the mouth plane 7 from a funnel shape, the two outer diffusers 2 and 4 having a deflection of approximately 90 °, as can be seen in particular in FIG. 3.
  • the bars 6, 8 arranged in a lattice arrangement are supported on a frame 9 so as to be adjustable with respect to their inclined position.
  • the adjustment can be carried out by hand or via a hydraulic slide 11 or via motor-driven spindle means, not shown.
  • 12 vibrator means 13 can engage on the actuating axis or spindle common to the rods, which the Reini additional effect.
  • two rulers 16 extend from the frame 9 outside of the bars 6, 8, which extend over the entire width of the device and extend beyond the support plane of the bars 6, 8 for the web 5, and serve to guide the web.
  • the bars 6, 8 are designed as scrapers or brushes on the support side of the web, which further increases the cleaning effect.
