Abstract (en)
[origin: US4670302A] Method and apparatus for wetting pourable solid matter. A preferred apparatus includes a tank (31) for accepting the solid matter, a mixing mechanism (32) for moving and breaking up the solid matter within the tank (31), at least one apparatus (5) for spraying the liquid substance supplied from a reservoir (11) into the tank, and an apparatus (2) for continuously feeding solid matter into the tank (31), characterized by the fact that the apparatus for spraying in the liquid substance includes at least one spraying nozzle (5) with an unchangeable (fixed) outlet opening (178) and a closure member (15, 16) that is to be opened (for aerating) and closed continuously, in a controllable sequence, that is connected to a feed line (9) that is under almost uniform pressure, and that is to be opened intermittently, for example electropneumatically, by control signals furnished from the apparatus (2) for supplying the solid matter.
Abstract (de)
Zum Hochdruckversprühen flüssiger Substanzen wie Leim wird vorgeschlagen, die flüssige Substanz unter konstantem Druck intervallweise zu versprühen, so daß eine Steuerung der versprühten Menge durch Verändern der Impulszeiten der Versprühung erfolgt, ohne den Druck, unter welchem versprüht wird, ändern zu müssen. Diese Art der Versprühung eignet sich besonders zum Beleimen von Spangut mit Leimen, die bei unsachgemäßer Verarbeitung gesundheitsschädliche Aerosole bilden können.
