Publication number: 20100065250Abstract: A method for transferring heat includes flowing a wastewater through a tank and flowing a fluid through a heat exchanger having an outer surface. The method further includes aerating the wastewater to produce a convective flow, contacting the outer surface of the heat exchanger with the convective flow to exchange heat, and cleaning the outer surface of the heat exchanger with the convective flow. A system for transferring heat includes a tank, a heat exchanger with an outer surface disposed in the tank, and a fluid flowing through the heat exchanger. Wastewater located in the tank flows over the outer surface of the heat exchanger, and a diffusion pipe disposed in the tank provides air into the tank to produce a convective flow in the wastewater.Type: ApplicationFiled: September 12, 2007Publication date: March 18, 2010Applicant: HANS HUBER AG MASCHINEN-UND ANLAGENBAUInventor: Christian Frommann

Patent number: 7638051Abstract: A filter apparatus in a container containing non-clarified contaminated liquid, especially wastewater, for clarifying this liquid consists of several spaced filter elements arranged in a circle or a polygon on a rotatably supported hollow shaft. The filter elements are connected to the hollow shaft in order to remove clarified liquid as permeate through the hollow shaft out of the container via a stationary pipeline. The rotating hollow shaft separates the wastewater from the permeate via at least two sealing elements. A blocking medium is arranged between the sealing elements.Type: GrantFiled: October 12, 2006Date of Patent: December 29, 2009Assignee: Hans Huber AG Maschinen-und AnlagenbauInventor: Bernhard Stadler

Patent number: 7572370Abstract: The invention relates to an installation for the mechanical purification of liquids, said installation comprising a container for separating suspended matter, and a transporting device for transporting the suspended matter to a discharge point. Said container comprising an inlet and an outlet for the liquid. A collecting chamber for suspended matter is formed in the bottom part of the container. The container for separating the suspended matter comprises at least two other chambers, at least one being embodied as a ventilated chamber and at least one as a non-ventilated chamber. The invention also relates to a method for separating suspended matter from liquids in a container comprising an inlet and an outlet for the liquid, and a collecting chamber for suspended matter in the bottom part thereof. According to said method, the suspended matter is separated in a multi-stage manner. At least one stage is a ventilated stage and at least one other stage a non-ventilated stage.Type: GrantFiled: July 5, 2005Date of Patent: August 11, 2009Assignee: Hans Huber AG Maschinen-und AnlagenbauInventor: Wolfgang Branner

Patent number: 7438810Abstract: A sieve device for insertion in a shaft has a connection for wastewater arriving in a supply device, which supply device is connected to a sieve surface of the sieve device for separating material to be separated from the wastewater. A worm conveyor transports the material to be separated out of the shaft. A fastening device is arranged in the shaft for the vertical fastening of the sieve device. The fastening device comprises a guide for the sieve device. An intersection is provided between the supply device and the sieve device. The guide positions the sieve device in front of the intersection when the sieve device is moved relative to the supply device into the shaft for purposes of mounting.Type: GrantFiled: June 29, 2006Date of Patent: October 21, 2008Assignee: Hans Huber AG Maschinen-und AnlagenbauInventors: Markus Lindl, Walter Blomenhofer

Patent number: 7344637Abstract: An apparatus serves for removing fine material to be screened from waste water. The apparatus includes a sieve grate (6) and a detaching device (16). The sieve grate (6) is cylindrical, and it is rotatingly driven. The sieve grate (6) allows for waste water to flow from its interior towards its exterior. The sieve grate (6) includes a supporting body (13) and a mesh sieve (7). The supporting body (13) is located at the exterior of the sieve grate (6). The supporting body (13) is made of a perforated sheet metal including comparatively large openings (37). The supporting body (13) provides for resistance and stability of the sieve grate (6). The mesh sieve (7) is located in the interior of the sieve grate (6). The mesh sieve (7) forms a separation surface (14) for the material to be screened. The mesh sieve (7) includes meshes of a comparatively small size. The mesh sieve (7) is fixedly connected to the supporting body (13). The detaching device (16) is arranged outside of the sieve grate (6).Type: GrantFiled: October 4, 2005Date of Patent: March 18, 2008Assignee: Hans Huber AG Maschinen-und AnlagenbauInventor: Christian Frommann

Patent number: 7318527Abstract: An apparatus (100, 100?, 100?) for separating organic material from inorganic material includes a container (1), a feeding apparatus (4), a charging apparatus (9), a lifting apparatus (21), a discharging apparatus (24) and a removal apparatus (7). The feeding apparatus (4) is located in the upper portion of the container (1), and it serves to introduce inorganic material polluted with organic material into the container (1). The charging apparatus (9) is located in the lower portion of the container, and it serves to introduce cleaning water into the container (1). The lifting apparatus (21) is located in the container (1), and it serves to substantially subject the inorganic and organic material to an upwardly directed component of movement. The lifting apparatus (21) and the charging apparatus (9) produce a fluidized layer (22) in the container (1) during operation of the apparatus (100, 100?, 100?). The fluidized layer (22) causes the organic material to be separated from the inorganic material.Type: GrantFiled: September 21, 2004Date of Patent: January 15, 2008Assignee: Hans Huber AG Maschinen-und AnlagenbauInventor: Wolfgang Branner

Patent number: 7037427Abstract: A filter device for the clarification of contaminated liquids includes a plurality of disk-shaped filter elements spaced apart from one another and combined into circular or polygonal filter modules. The filter elements are arranged rotatably about a horizontal axis in a vessel containing the unclarified liquid. The filtrate is capable of being discharged via the individual filter modules. The filter modules form centrally a cavity. The cavity on one side is closed by a carrying disk and on the other side is connected to the vessel via a suction-intake orifice. The cavity is connected operatively to a flow member in such a way that, via the suction-intake orifice, a flow can be generated in the unclarified liquid between the spaced-apart filter elements and avoids an adhesion of solids to the filter elements.Type: GrantFiled: April 19, 2001Date of Patent: May 2, 2006Assignee: Hans Huber AG Maschinen-und AnlagenbauInventors: Eberhard Harms, Mark Grigo
