| 20080277087 | Screen Cylinder - A screen cylinder comprising screen slots ( | 11-13-2008 |
| 20090025899 | Apparatus for Cleaning a Fiber Suspension for a Papermaking Process - An apparatus for cleaning a fiber suspension for papermaking of foreign substances contained therein, such as sand, metal parts, glass splinters, bark fragments and the like, by using a tubular, vertically aligned housing, which is constructed with an inlet for the introduction of the fiber suspension into this housing under pressure, also provided at its lower end with an outlet for discharging the foreign substances contained in the fiber suspension and at its upper end with an outlet for leading off the fiber suspension freed of the foreign substances. In this case, at least a portion of the housing, or the lower housing parts, or at least a casing that encapsulates the lower housing parts, are produced from a transparent or a see-through material, in particular from a transparent or a see-through plastics material. | 01-29-2009 |
| 20090218065 | Arrangement for the Treatment of Cellulose Pulp Involving Seal Positioning Means - A washer for washing and dewatering cellulose pulp is disclosed, comprising a rotary drum with a plurality of external compartments on the drum defined by axial compartment walls distributed along the circumference of the drum, a stationary cylindrical casing enclosing the drum, defining a ring-shaped space between the casing and the drum, and longitudinal seals in the axial direction of the drum diving the ring-shaped space into a forming zone for forming the pulp, at least one washing zone for washing the pulp at an overpressure, and a discharge zone, and where the longitudinal axial seals are attached to positioning cylinders for adjusting the radial position of the seals, and the longitudinal seal has an articulated connection with the positioning cylinders to make possible oblique positioning of the seal. | 09-03-2009 |
| 20090229778 | Arrangement For Treatment Of Cellulose Pulp - A washer for washing and dewatering of cellulose pulp is disclosed, comprising a rotatable drum with a plurality of outer compartments for the pulp to be washed defined by axial compartment walls distributed along the circumference of the drum, a stationary cylindrical casing that encloses the drum, whereby an annular space is defined between the casing and the drum, the annular space divided by means of longitudinal seals in the axial direction of the drum into zones for forming, washing and discharge of the pulp. At least two of the longitudinal seals are arranged such that, when the drum rotates, they meet compartment walls at shifted points in time with respect to each other. Preferably, all of these longitudinal seals are arranged along the circumference of the drum at different positions with respect to respective opposite axial compartment walls. | 09-17-2009 |
| 20090277599 | TANK ASSEMBLY FOR MAKING FIBRE PRODUCTS FROM STOCK - The present invention relates to a tank assembly for making fibre products from stock comprising a stock vat, a main tank ( | 11-12-2009 |
| 20100059194 | SCREEN - The present invention relates to a method for the production of a screen and to a screen for the treatment of a fibrous material suspension suitable for the production of a fibrous material web, the screen including at least two screen layers that are connected to each other and have apertures, at least some of the apertures being arranged in such a way that the result is screen openings leading through the screen. The production of the screen is simplified in that some of the apertures are arranged in such a way that the result is recesses on the front side of the screen which do not pass through the screen, and at least the apertures forming the recesses are introduced into the screen layers before the latter are connected. | 03-11-2010 |
| 20110061829 | METHOD FOR DEGASSING AND SUPPLYING A FIBROUS SUSPENSION TO A HEADBOX OR A FILTER DEVICE AND DEGASSING DEVICE - Degassing device that includes a housing, a rotor having a rotatable interior arranged within the housing, an inlet for adding a liquid to be degassed, the inlet being structured to open into the interior of the rotor, and an outflow for a degassed liquid. A degassing tube is centrally arranged with respect to the interior to remove gas escaping from the liquid. The rotor includes at least one opening structured and arranged to produce an hydraulic connection with the outflow. | 03-17-2011 |
| 20110290444 | SCREENING IN AN APPROACH FLOW SYSTEM - The invention relates to an arrangement for obtaining a fiber suspension for producing a web of paper, cardboard, tissue, or other fibers from at least one high-consistency flow containing fibrous material and filling material in the approach flow system of a fiber web manufacturing machine, at least one high-consistency flow being directed through at least one screening device. In order to reduce the screening effort, the accept from the screening device is directed to the headbox of the machine, and the reject from the screening device is redirected upstream into a high-consistency flow. | 12-01-2011 |
| 20120012271 | Device for Dilution of Cellulose Pulp - 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 Liq.sub.LEV 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. | 01-19-2012 |
| 20140190646 | PAPERMAKING SCREEN APPARATUS - A screen apparatus includes a tank receiving a papermaking raw material; a screen partitioning the tank into a primary chamber and a secondary chamber; a papermaking raw material supply passage for supplying a papermaking raw material to the tank; a foreign material discharge passage for discharges the papermaking raw material containing a foreign material that does not pass through the screen to the outside of the tank; a papermaking raw material discharge passage communicating with the secondary chamber, and discharging the papermaking raw material passing through the screen to the outside of the tank; a cylindrical rotor body rotatably provided inside the screen, and stirs the papermaking raw material in the primary chamber; and a stepped stirring member provided on the side surface except for both end surfaces of the rotor body. The stepped stirring member is formed at a falling gradient with respect to a papermaking raw material flow. | 07-10-2014 |
