Definitions

  • the invention relates to a method for cleaning bodies, in particular containers to be introduced into a clean room.
  • This object is achieved in that the bodies are introduced into a cleaning chamber and their surface is subjected to cleaning air jets directed into the interior of the cleaning chamber and towards the body, at the same time extracting dust-laden air from the cleaning chamber.
  • body means bodies such as Tanspori containers, motor vehicle bodies or the like. On the surface of which dust can settle and the size of which allows exposure to cleaning air jets.
  • the directional blowing of the surface of the body in the cleaning chamber removes the dust adhering to the surface of the body and whirls it up.
  • the simultaneous suction ensures that the dust cannot settle on the body again.
  • the body e.g. B. container
  • the body after cleaning in a clean room, it is appropriate that the body be placed in a lockable cleaning chamber and cleaning is carried out after closing the chamber and that after the cleaning with air and after the suction of air has ended the body is brought directly into a clean room after opening the cleaning chamber.
  • the individual body is preferably moved through the cleaning chamber and subjected to at least oppositely inclined blast air jets from two blown air sources arranged at a distance when viewed in the direction of movement of the body, and air is sucked out of the cleansing chamber between the two blown air sources.
  • the air blown into the cleaning chamber and the air extracted from the chamber is guided in the circuit, since then less or, if the cleaning chamber can be closed, no dust can be sucked into the circuit from the surroundings of the chamber.
  • purge air is blown into the cleaning chamber at the ends of the cleaning chamber.
  • the invention is also directed to an apparatus for performing the method.
  • this is characterized in that an elongated cleaning chamber is provided, that at least two spaced-apart air blow-out devices are arranged in the chamber, the blow-out cross-sections of which ring-like surround a body moved through the chamber and whose blow-out flows are inclined in the opposite direction to the direction of movement of the body, and that in As seen in the direction of movement, at least one air suction device is provided between the two air blowing devices.
  • the term “ring-like” is understood to mean both a ring-like configuration and a configuration constructed from polygonal lines.
  • the discharge cross sections can be arranged in a rectangle or square encompassing the body.
  • the ring-like configuration can thus be formed when the discharge cross sections are formed as slots through two vertical slots and two horizontal slots.
  • Description of a ring-like not necessarily a 360 0 covering ring understood.
  • a not completely closed ring-like configuration can also be used. It is only important that the surface of the body is cleaned of dust by the area of action of the air-blowing devices when the body is moved.
  • the cleaning chamber is provided with closure devices at both ends.
  • a transport device is provided in the cleaning chamber for transporting the bodies from one end of the chamber to the other.
