Publication number: 20080164186Abstract: Disclosed herein is a method for separation of construction waste. In the method, the construction waste, crushed to a predetermined size, is added to liquid in a precipitation tank and separated into components in the tank according to specific gravity, in which the liquid has a reference specific gravity lower than that of a component to be recovered but higher than that of the remaining components, such that only the component to be recovered is separated by precipitation to the bottom of the precipitation tank. According to the method, high-quality recyclable aggregate contained in the construction waste can be easily separated from other impurities through a simple process. Particularly, the reference specific gravity of the separation liquid is suitably adjusted so that the recyclable aggregate can be easily separated even from impurities (tiles, red brick, asphalt concrete, cement paste mass, etc.) heavier than water, unlike the prior separation process using an aerated water tank.Type: ApplicationFiled: September 23, 2005Publication date: July 10, 2008Inventors: Heon-Chan Kang, Kyoung-Rok Kong

Patent number: 7341154Abstract: A water bath separator includes a tank for receiving a volume of water for forming a water bath having a top water surface and a light material conveyor path extending from the tank such that an upstream end of the light material conveyor path is closely below the top water surface when the tank is in filled operating condition. The light material conveyor path includes a sorting conveyor provided with a row of rotatable, driven shafts mutually spaced in a conveying direction and each extending transversally to that conveying direction. The shafts each carry a row of radially extending impellers for intermittently urging material on the sorting conveyor upward and in conveying direction, the impellers of each of said rows being mutually spaced in longitudinal direction of the respective shaft. The sorting conveyor has an upstream portion located in the tank such that an upstream end of the sorting conveyor is immersed in the water bath when the tank is in filled operating condition.Type: GrantFiled: March 24, 2005Date of Patent: March 11, 2008Assignee: Bollegraaf Beheer Appingedam B.V.Inventor: Pieter Boer

Patent number: 6695147Abstract: This invention provides an extraction device and a method for extracting desired particles from a sample stream containing the desired particles. The device has a sample stream inlet, an extraction stream inlet, and an extraction channel in fluid communication with the sample stream inlet and the extraction stream inlet. The extraction channel is for receiving a sample stream from the sample stream inlet in adjacent laminar flow with an extraction stream from the extraction stream inlet. A sequestering material within the extraction channel captures desired particles in the extraction stream. A by-product stream outlet in fluid communication with the extraction channel receives a by-product stream comprising at least a portion of the sample stream form which desired particles have been extracted. A product outlet in fluid communication with the extraction channel receives a product which has the sequestering material and at least a portion of the desired particles.Type: GrantFiled: October 12, 1999Date of Patent: February 24, 2004Assignee: University of WashingtonInventors: Paul Yager, James P. Brody

Patent number: 6666338Abstract: A device for the separation of solid objects (9) from fluid flowing in a conduit tube (2) includes a housing that includes a tubular outer wall (3) and a tubular inner wall (4). Between these is delimited a collecting space (8). Concentrically relative to the inner wall (4) is provided a rotation-symmetrical central body (12) which at opposing ends cooperates with flow converting devices (15, 16), which transform incoming flow to a rotative motion and outgoing flow to an axial motion. In the inner wall (4) are recessed tangentially separated holes (20) of elongated shape, through which the scrap objects may pass and be collected in a collecting space (8). In the collecting space (8) a calm flow operation is obtained which guarantees that collected scrap objects are not carried away and returned to the main fluid flow through the separation device.Type: GrantFiled: September 14, 2001Date of Patent: December 23, 2003Assignee: Vattenfall ABInventors: Mats Henriksson, Anders Lundström, Rolf Karlsson, Tapio Kaipanen, Johan Westin

Publication number: 20030019595Abstract: A method of draining water from low-consistency water-fiber suspensions, in which the water-fiber suspension is fed to a filtering surface comprising holes. The rougher fibers are first separated from the water-fiber suspension and fed to the filtering surface to form a separate filtering layer and the water-fiber suspension is led to flow through the filtering layer formed by the rougher fibers.Type: ApplicationFiled: June 24, 2002Publication date: January 30, 2003Applicant: Metso Paper, Inc.Inventor: Vesa Juutinen

Publication number: 20010022283Abstract: Dense, tramp material, is efficiently separated in a comminuted cellulosic fibrous material feed system, for example in a chemical cellulose digester feed system, in a simple but effective matter. By merely utilizing a generally vertical conduit and a slurry flow within it (which may be augmented by high speed liquid introduction), that is caused to turn in a radiused path, centrifugal force allows separation of the tramp material into a cavity beneath the radius transition without requiring any mechanical element to engage the slurry. Appropriate purges, baffles, and discharge mechanisms may be provided. Alternatively, a tramp material separator may be built into an otherwise conventional metering screw in a digester feed system, or one or more centrifugal separators can be provided downstream of the slurry pump in a chip slurry transport system or digester feed system.Type: ApplicationFiled: May 17, 2001Publication date: September 20, 2001Applicant: Andritz-Ahlstrom Inc.Inventors: Vic L.
