Definitions

  • the invention relates to a flange joint for connecting two objects in a fluid connection so that fluid can flow between the objects as defined in the preamble of the independent claim 1.
  • the invention relates also to a hindered-bed settler for separating particles of hydrous slurry as defined in the preambles of independent claims 8 and 9.
  • the invention relates also to a method for preventing clogging in an apparatus comprising several objects between which fluid flows as defined in the preamble of the independent claim 13 and to a method for preventing clogging in a hindered-bed settler as defined in the preamble of the independent claim 14.
  • the present invention relates to moving solids inside an object or an apparatus or inside a part of apparatus for example in a pipeline or similar with fluid for the sake of transportation, sizing or classifying. Problems occur when for some reason the fluid moves forward but does not carry the solid material along. The motion of the solid material then slows down and finally stops. The solid material starts to accumulate and ends up with blocking the object.
  • water should be added on the way continuously for process reasons or temporarily for improved material flow, to open a blockage or to add for example reagents into a process flow in a pipeline or in a process equipment.
  • Prior art teaches in DE 102006050783 B4 a pre-masher for production of mash from coarsely grind malt or cereal.
  • the pre-masher comprises a downpipe that guides a groat flow, a supply of mash water intended over a housing and distributor flanges.
  • the mash water is radially guided through openings of the flanges over a distribution chamber into a mash water gap, which is formed by suitable concentric surface geometry of the two flanges.
  • the geometry of the components forming the mash water gap is isolated.
  • the cross section of mash water openings or the mash water gap is varied by replacement of flange-shaped components.
  • the tube forming a mixing chamber is mounted through dismantlable tie rods between the two flanges and is sealed by a sealing.
  • flange connections are used above and/or below the pre-masher.
  • the replaceable flange contains concentric openings for the mash water that produces a partial flow of water in downward manner.
  • the mash water flow is set out by the openings by one of the cross-section contraction of the down flow resulting from a recess of the connection flange of the mixing chamber and/or resulting from reducer of mixture turbulences.;
  • the annular- shaped mash water flow guided downwardly to the center by the annular gap hits on a double cone displacement body.
  • the groat flow guided along the lower cone by the displacement body is led downwardly in a turbulent flow.
  • a partial flow of the mash water hits on the displacement body by the openings so that adhering dust particle is kept free during the single mashing process.
  • the cleaning medium is supplied over openings into the outer contour of the pre-masher in such a manner that a chamber is cleaned around the mash water gap without additional components reaching into the downpipe.
  • a tangential tubing connection with a shutoff device is used for the cleaning of an intake pipe of the pre-masher and the downpipe by the cleaning medium.
  • the mash water is supplyable through radial or a combination of radial and axial openings into the flange.
  • the object of the invention is thus to provide a flange joint with a gasket which alleviates the problems mentioned above.
  • Preferred embodiments of the flange joint are defined in the dependent claims 2 to 7.
  • the hindered-bed settler for separating particles of hydrous slurry is characterized by the definitions of the independent claim 8 and by the definitions of the independent claim 9.
  • Preferred embodiments of the hindered-bed settler according to claim 9 are defined in the dependent claims 10 to 12.
  • the method for preventing clogging in an apparatus comprising several objects between which fluid flows is characterized by the definitions of the independent claim 13 and the method for preventing clogging in a hindered-bed settler is characterized by the definitions of the independent claim 14.
  • the invention relates to a flange joint having a gasket and the said gasket being installed in the flange joint and that the flange joint has at least one channel for feeding additional fluid from outside of the flange joint through the gasket into fluid flowing between two objects.
  • a normal gasket in a flange joint can be replaced with a gasket according to the invention where the gasket has at least one distribution channel for fluid such as water. Also chemicals and gases can be distributed in said at least one channel.
  • the present invention relates particularly to a hindered-bed separator or a hindered-bed settler or similar separator or a thickener or a cyclone or a flotation cell or a settler apparatus or other type of equipment handling with solids that can settle in the equipment and block the valve of the equipment (hereinafter "hindered-bed settler") to partition solid particles in hydrous slurry or pulp into two or more fractions containing particles of different size and density.
  • the present invention can also be used in a connection with other equipments where solids are moved with fluid for the sake of transportation, sizing or classifying. In this application fluid stands for any liquid or gas that can flow.
  • Many sizing and classifying methods employ gravity of solid material in hydrous slurry with an incoming feed containing the material encountering an upward fluid flow.
  • the variation in size and/or density will result in heavier particles falling to a lower level and lighter particles being uplifted to an overflow level thus affecting the desired separation.
  • the hindered-bed settler handling solid material such as sand material, mineral slurries, hydrous slurries, pulp or other same kind of material (hereinafter "hydrous slurry”) comprises a body defining an inner space, having a plurality of feed points for even fluid distribution, advantageously water distribution, at a lower portion of the chamber.
  • a separate feed well means for introducing hydrous slurry into the inner space of the hindered-bed settler. All the material flows downward until it is discharged into the main chamber at a desired level.
  • faster settling particles move downwardly and are removed through coarse feed outlet by various means for example through a valve.
  • the rising fluid advantageously water, carries light particles upward over the top of the inner space of the body into the overflow launder.
  • the heavier solid material sinks downward while the lighter solid material goes upward.
  • the inner space of the body is closed by a colonial dewatering or liquid separation cone with an outlet valve at the bottom.
  • the heavier solid material, the coarse feed sinks to the bottom part of the cone where the grains of the coarse feed will stay close to each other while the fluid such as water flows between them.
  • the body can be closed by a part shaped other than conical for example by a narrowing shaped part.
  • What is desired in a hindered-bed settler handling solid material is that fluid such as water needs to be added either continuously for process reasons or temporarily for improved material flow or to open a blocked valve.
  • fluid such as water needs to be added either continuously for process reasons or temporarily for improved material flow or to open a blocked valve.
  • fluid such as water needs to be added either continuously for process reasons or temporarily for improved material flow or to open a blocked valve.
  • fluid such as water takes place through different sorts of nozzles, holes in a box-type structure or holes in a pipe.
  • Adding fluid feeder points to the hindered-bed settler after installation, if necessary, is difficult. This is especially true if the tank has some kind of lining such as rubber that will then be damaged. The same is true in regard of painting.
  • the idea of the invention is that in order to prevent the hindered-bed settler handling with solids to be blocked, fluid such as water has to be added to the lower part of the said hindered-bed settler.
  • fluid such as water is needed in the cone part of the hindered-bed settler or in the narrowing shaped part of the hindered-bed settler.
  • a flange joint with a specially made gasket installed in a flange joint is coupled in the hindered-bed settler.
  • the gasket is at least partly made of polymer, advantageously of polyurethane.
