  • Patent number: 4498934
    Abstract: A method for cleaning dirty objects using cleaning fluid and rinsing fluid and an apparatus using the method. The method has consecutive steps of spraying the surface of a dirty object with high pressure spray of cleaning fluid, immersing the dirty object in an immersion chamber containing cleaning fluid, spraying additional cleaning fluid at high pressure into the immersion chamber at a location downstream from the initial location where the dirty object is immersed to turbulate cleaning fluid therein to scrub the surface of the dirty object, removing the dirty object from the immersion chamber, and spraying the surface of the dirty object with a high pressure spray of rinsing fluid.

  • Patent number: 4344448
    Abstract: An apparatus for cleaning dirty objects with fluids is disclosed. The apparatus has a housing within which a high pressure wash chamber is located at the input end of the housing. A high pressure rinse chamber is located at the discharge end of the housing. An immersion chamber containing cleaning fluid is disposed between the wash chamber and the rinse chamber. The dirty objects are moved serially through the wash chamber, the immersion chamber and the rinse chamber to clean the dirty objects by mechanical scrubbing and chemical action. A guide rail system is provided to insure that dirty objects less dense than the cleaning fluid are submerged into the cleaning fluid in the immersion chamber. In the preferred embodiment, ultrasonic transducers are mounted in the immersion chamber below the level of the chemical fluid to generate vibrations to loosen and remove a portion of the dirt therein.
