Patent number: 11007541Abstract: A dust collecting device using multi-cyclone dust filtration includes a dust collecting chamber, cyclone chamber and airflow guiding component. The dust collecting chamber communicates with the cyclone chamber having an intake port for a gas to be filtered, an annular side wall connected to intake port and guiding gas to be filtered to form a first cyclone, an engaging port communicated with dust collecting chamber and allowing first cyclone to enter dust collecting chamber, and an exhaust port. The airflow guiding component within cyclone chamber is provided with a return flow tube receiving the returned gas to be filtered and forming a second cyclone, an airflow guiding bonnet separated from return flow tube, and a dust filtration channel between airflow guiding bonnet and return flow tube. The second cyclone flows toward the exhaust port, and enables dust therein to enter cyclone chamber again, as passing by dust filtration channel.Type: GrantFiled: April 23, 2018Date of Patent: May 18, 2021Assignee: X'Pole Precision Tools Inc.Inventor: Bach Pangho Chen

Patent number: 8506824Abstract: A method for treating waste water and sewage by introducing high pressure wash water or other fluids including gas into a housing of a hydro-cyclone and creating a cyclone with an enhanced and controllable vortex for increased removal of putrescible materials. Waste water and sewage is introduced into the housing and into the cyclone vortex. By the very high centrifugal force generated, suspended inorganic grit is quickly separated from the wash water and organic matter. The water with organic matter is then discharged typically out of the top of the housing, for returning to a water treatment plant for further processing. At this time, the separated inorganic grit, as a concentrated grit liquid, is typically funneled downwardly by gravity through a bottom of the hydro-cyclone housing for waste discharge removal.Type: GrantFiled: May 16, 2012Date of Patent: August 13, 2013Inventor: Charles M. Schloss

Patent number: 6109119Abstract: Sample focusing method and device for field-flow fractionation techniques that lead to improved detection, improved separation resolution, and a compressed sample plug while permitting a more straightforward quantitation of peaks and reliable large volume injections. The method and technique can be implemented in separations that are performed by a variety of field-flow fractionation techniques, including thermal FFF, electrical FFF, sedimentation FFF, gravitational FFF, dielectric FFF, photophoretic FFF, flow FFF, asymmetric flow FFF, and symmetric flow FFF. The sample focusing device can be integrally built into a separation channel or it can be manufactured as an attachable independent piece.Type: GrantFiled: February 27, 1998Date of Patent: August 29, 2000Assignee: FFFractionation, LLCInventors: Yong Jiang, Marcia E. Hansen, Michael E. Miller, Andreas M. Kummerow

Patent number: 5788083Abstract: The invention proposes an elbow/countercurrent classifier by means of which a pneumatically introduced bulk-material stream can be separated into coarse fractions and fine materials. In order to increase the efficiency of the classifier as regards the separating action, a wall profile which results in increased turbulence of the gas streams is selected, in particular, in the region of the acceleration section and of the classifying section which adjoins the latter at the bottom. This produces a rise in the air velocity in the vicinity of the wall and thus an air velocity which is constant over the cross section.Type: GrantFiled: October 22, 1996Date of Patent: August 4, 1998Assignee: Zeppelin Schuettguttechnik GmbhInventor: Wolfgang Krambrock

Patent number: 5749470Abstract: An installation for decontaminating a radioactively contaminated surface with a dry mechanical abrasive includes an extractor for suction extraction of an extraction gas together with an abrasive/dust mixture produced during blasting. A separator separates the abrasive/dust mixture aspirated by the extractor into a dust fraction and a re-usable abrasive fraction. A storage bin is connected between the extractor and the separator. The storage bin includes a filter device having a filter for filtering the extraction gas flowing through the storage bin to the extractor, and a blowoff line to be connected to the filter device for blowing off the filter.Type: GrantFiled: December 8, 1995Date of Patent: May 12, 1998Assignee: Siemens AktiengesellschaftInventors: Hermann Operschall, Jakob Weber, Klaus-Alfred Steiner, Stefan Ring

Patent number: 5466384Abstract: A device for separating a mixture comprised of at least a continuous phase I and at least a disperse phase II, one of the phases being a light phase and the other being a heavy phase, comprising canalization means for canalizing a current of the mixture and suited for communicating thereto a helical motion along a central shaft (A) and filtration means, the motion leading to a differentiated radial displacement of the light phase and of the heavy phase under the action of the centrifugal force, during which the continuous phase I flows at least partly through said filtration means. The canalization means and filtration means are arranged to define a helical passage which decreases according to a direction of flow of the mixture through the device.Type: GrantFiled: November 5, 1993Date of Patent: November 14, 1995Assignee: Institut Francais du PetroleInventors: Isabelle Prevost, Alexandre Rojey
