Definitions

  • the present invention relates to a method and apparatus for cleaning floor mats such as when using a continuous batch washer or tunnel washer.
  • the present invention relates to the cleaning of particulate laden material (such as floor mats, sand laden beach towels, work uniforms laden with metal shavings, or jeans laden with pumice rock such as the pumice rocks used in garments washing such as stone washed jeans) in a multiple module washer (e.g., tunnel washer) wherein a specially configured recirculation arrangement transmits liquid from a module (e.g., first module) to an intake or hopper and wherein a pump and filter in between the module and intake effect a removal of particulate material such as sand, metal shavings, or rocks during such recirculation.
  • a module e.g., first module
  • a pump and filter in between the module and intake effect a removal of particulate material such as sand, metal shavings, or rocks during such recirculation.
  • a floor mat The purpose of a floor mat is to wipe or otherwise remove sand and dirt from the feet of people.
  • dirty floor mats can be laden with significant quantities of heavy dirt or sand.
  • Towels can be laden with sand and thus pose a problem for a resort hotel laundry.
  • Metal shavings from uniforms used in the metal work industry can cause problems for a laundry.
  • Other items to be laundered can be laden with pumice rocks used in garment washing such as stone washed jeans.
  • One of the problems with washing floor mats embedded with sand is that once the sand is released from the mat into the washing water, the sand collects inside the shell of the washing machine such as in many of the modules of the tunnel washer. Periodically, the machine is programmed to insert a purge pocket which drains the water and hopefully most of the sand and organic compounds. If the sand and organic compounds are not removed, they build up in the machine. This causes the mats to not be cleaned. The build up of organic compounds causes the mats to have an extreme odor.
  • Patents have issued that are directed to batch washers or tunnel washers.
  • the following table provides examples of such patented tunnel washers, each listed patent of the table being hereby incorporated herein by reference.
  • the present invention provides an improved method and apparatus for washing floor mats in a tunnel washer.

  • a washing chemical can be added to the volume of liquid, after a selected time period, and counter flowing a rinsing liquid along a flow path that is generally opposite the direction of travel of the material.
  • a volume of liquid can be recirculated from the first module to the intake via a recirculation flow line. Particulate matter can be removed from the volume of liquid flowing in the recirculation flow line with a filter after the volume of liquid leaves the first module and before the volume of liquid reaches the intake.

Abstract

L'invention concerne un procédé de lavage d'un matériau chargé de particules dans un appareil de lavage, ledit procédé consistant à déplacer le matériau chargé de particules de l'entrée de l'appareil de lavage jusqu'à la sortie de l'appareil de lavage et à travers de multiples modules ou secteurs. Du liquide peut être introduit à contre-courant à l'intérieur de l'appareil de lavage le long d'un trajet d'écoulement qui est généralement opposé à la direction de déplacement du matériau chargé de particules. Un agencement de recirculation/filtration spécialement configuré élimine la plus grande partie des particules et de la matière organique se trouvant dans le fluide de lavage.
