Patent number: 8794552Abstract: Apparatus for separating components of post-consumer carpet—pile, adhesive, and primary/secondary backings—may initially comprise spectrographic face fiber identification. Separating substantial portions of pile from backing comprises feeding carpeting into a rotating pinned drum, with separated pile U's dropping, while a residual composition, being primarily backing, travels with the drum, to be separated therefrom using vacuum pressure, with the composite backing being sent to a press. Vacuum pressure delivers the separated U's to a spinning perforated squirrel cage to remove dislodged pieces of adhesive, by vacuum pressure applied to an interior top portion of the cage to draw pieces therein. Rotating the perforated squirrel cage, which is sealed on the exterior using a belt, permits the U's to drop into a hopper. A mesh shaker box vibrates to separate any remaining backing from the pile U's. Hammers in a fibermill remove remaining adhesive attached to the separated pile U fiber.Type: GrantFiled: December 31, 2012Date of Patent: August 5, 2014Inventors: Frank J. Levy, Sergio Dell'Orco

Patent number: 7887671Abstract: The method and a device is for the dilution of dewatered cellulose pulp that maintains a consistency of 20-30% or greater. By shredding of the pulp to a finely divided dry-granulate, dilution to a homogeneous consistency in the medium consistency range can take place exclusively through hydrodynamic effects from the addition of dilution fluid. The dilution fluid is added to granulate at a position at which granulate is in free fall in a standpipe and above a level LiqLEV of diluted pulp in the standpipe. A number of nozzles are arranged around the periphery of the stand pipe, directed in towards the centre of the stand pipe, obliquely downwards in the direction of fall of the granulate. It is possible through this simplified procedure to avoid completely the conventional dilution screws, and this reduces the investment costs and operating costs, while at the same time unnecessary mechanical influence of the pulp fibres can be avoided.Type: GrantFiled: March 9, 2005Date of Patent: February 15, 2011Assignee: GLV Finance Hungary Kft.Inventors: Vidar Snekkenes, Lennart Gustavsson, Jonas Saetherasen, Goran Olsson

Publication number: 20080041982Abstract: The present invention is a system and method for creating a coal replacement wood waste fuel produced from waste construction and demolition refuse. Construction demolition refuse is gathered and separated into recyclable items and non-recyclable items. Then, larger recyclable items are conveyed to a picking room and smaller recyclable items are screened to remove dirt and gravel. The larger of the smaller particles are then re-united with the larger recyclable materials. Non-fuel products are picked off a conveying system and discarded or recycled otherwise. The fuel products remaining on the conveying system are ground into a coal replacement wood waste fuel. Wet or dry fuel supplements may be added to the wood waste fuel. Additionally, the fuel may be gasified to create a burnable gas.Type: ApplicationFiled: July 31, 2006Publication date: February 21, 2008Applicant: ENVIRONMENTAL RECLAMATION AND RECYCLING, L.C.Inventors: JONATHAN C.
