Definitions

  • the present invention relates to a spreading device for spreading granular material such as salt, slurry, sand, grit, aggregate, brine and/or powdery materials mixed with a liquid such as water, comprising a disc with a central bore adapted to rotate around an axle/shaft placed in said bore, said axle/shaft being driven by moving means, said disc supporting a number of wings for spreading the material, the spreading device further comprising a mixing chamber for mixing the liquid and the granulated material, said mixing chamber comprising a wall in which a discharge opening is provided.
  • DE 19933647 describes a spreading device comprising a rotatable disc for spreading granular moisture material such as brine and road salt. It comprises a chamber in which brine is placed. The chamber comprises an opening and closing distribution member such as a brush which is placed above the spreading disc. A funnel guides grid such as salt to the rotating spreading plate.
  • the spreader device does not provide a mixture before the brine and the salt reach the rotating spreading plate and therefore, the delivered substance may be quite unevenly mixed and thereby unevenly distributed.
  • EP1670992 discloses a spreader arrangement for a road machine. It comprises a rotating disc and a mixing chamber placed at the centre of the rotating disc. Liquid and granular material such as salt is led to the mixing chamber. In the chamber, mixing blades made in metal or other expensive materials are provided. They are exposed to great friction and thereby, they are worn out quite fast and must be replaced. This is an expensive and troublesome process.
  • EP1634997 discloses a spreading device for spreading granular material comprising a mixing disc with flexible means for mixing materials and discharging it through openings during rotation of the mixing disc.
  • a disadvantage with this solution is that the spreading device does not allow for an active and controlled transfer of the liquid-granular solution.
  • the spreading device further comprises a mixing disc adapted to rotate together with the disc, said mixing disc comprising a bore being coaxial with the central bore of the disc, the mixing disc comprising flexible means placed at the periphery of the mixing disc, said flexible means being adapted to mix the liquid and granular material and guide the mixed materials through the discharge opening to the wings during rotation of the mixing disc.
  • the mixing disc has a substantially circular periphery and the periphery is placed at a distance d1 from the inner surface of the wall of the mixing chamber, said wall being substantially circular in cross section and the free end of the flexible means being placed at a distance d2 from the inner surface of the wall of the mixing chamber, said distance d2 being larger than 0mm and smaller than d1.
  • the periphery of the mixing disc By placing the periphery of the mixing disc at a distance from the wall of the mixing chamber, sufficient place for the elongated fibres is obtained. Thereby, their function is improved.
  • the distance is around 45mm.
  • the fibres are the part of the rotating mixture disc being worn during the friction between the material and the fibres.
  • the wall of the mixing chamber is made in a wear-resistant material while the fibres are made in a softer material, which is why they are worn out.
  • the distance d2 is around 1-3mm. It is avoided that the rotation force is transferred from the rotating mixing disc to the delimiting walls of the mixing chamber.
  • the salt or other granular material is led from a container through a funnel and down to the mixing chamber. Water or brine is led to the mixing chamber from another inlet.
  • the mixing chamber is delimited by a cylindrical, vertical wall and at the bottom, the mixing disc is placed.
  • the mixing disc is rotating around the axle of the spreading disc and is attached to the rotating disc. However, the two discs may rotate with different speed independently of each other.
  • the flexible means being placed at the periphery of the rotating mixing disc.
  • the flexibility of the means ensures that an excellent mixing of the two components takes place. Further, the flexible means also press and direct the mixture through the discharge openings.
  • the flexibility has the advantage that the flexible means mix the substance very well.
  • the flexibility is chosen in such a way that on one hand, an optimal mixing of the substance takes place and on the other hand, the flexible means are so stiff that the mixture is directed out through the discharge openings.
  • the flexible means are brushes formed by filaments/fibres/.
  • the fibres are cylindrical or oval in cross section and advantageously, they are formed in a synthetic material such as a polymer, for instance PBT.
  • the diameter of each cylindrical fibre is 1-2mm, preferably 1.5mm.
  • the mixing disc Due to the construction of the mixing disc as such, it is easy to replace the disc without replacing the rest of the mixing chamber as it is a part of the mixing disc - the elongated fibres - that is being worn.
  • the fibres are placed in bundles, each bundle comprising around 8-16 fibres, preferably around 12 bundles.
  • the bundles are substantially cylindrical.
  • the spreading device is fixed/attached to a suitable vehicle comprising a motor for rotating the disc around a shaft.
  • a container is placed in connection with the rotatable spreader disc.
  • the container contains the granular material to be distributed. Then, the material is led down to the rotatable mixing disc. Fluid is led down to the rotating mixing disc as described above.
  • the flexible means comprise elongated flexible means spaced apart and attached to the periphery of the mixing disc.
  • the flexible means By forming the flexible means as elongated devices, the mixing and guiding properties are improved.
  • the flexible means may be arranged in bundles of fibres, said bundles being spaced apart. Having a certain distance between each bundle ensures an even, controlled mixing and spreading pattern.
  • each elongated flexible means is substantially circular or oval.
  • This shape of the cross-sectional area ensures that the flexible properties of the flexible means are properly regulated.
  • the mixing disc comprises a mixing upper surface and an oppositely placed mixing lower surface, said upper surface pointing towards the wall of the mixing chamber and comprising a number of grooves being spaced apart, each groove having an opening in the periphery of the mixing disc.
  • the granular and the liquid are caught in said grooves.
  • the mixture is led to the openings of the grooves placed at the periphery of the mixing disc. Due to the centrifugal force, the mixture is hurled outwards and hits the inner surface of the wall of the mixing chamber.
  • the rotating flexible means support the mixing by pressing it towards the inner surface of the wall leading the mixture out through the discharge opening.
  • the mixed material leaving the rotating disc falls in a parabolic curve.
  • the grooves comprise a bottom wall, two oppositely placed side walls and a back wall connecting the three walls, said bottom wall being inclined downwards and towards the periphery of the mixing disc and the opening.
  • the flexible means are arranged in at least two circumferential rows placed in the periphery of the mixing disc, said one row being placed above the other row.
  • bundles of elongated flexible means are placed in the periphery of the mixing disc and between the openings of the grooves, and the bundles are arranged in such a way that at least two bundles of elongated flexible means are places between two neighbouring openings, said bundles being placed with one bundle placed above the other bundle.
  • the mixing disc comprises several displaceable disc parts for forming the mixing disc, said each displaceable disc part comprising at least one groove and flexible means attached to the periphery of said disc part.
  • some parts of the mixing disc are provided with additional flexible means compared to other parts of the mixing disc, said additional flexible means being placed above the other flexible means.
  • the additional flexible means have the purpose of cleaning the mixing chamber whereby clogging of the substance is avoided.
  • the flexible means being detachably attached to the periphery of the mixing disc.
  • the mixing disc is a replaceable part comprising fastening means for fastening the mixing disc to (the upper surface of) the disc.
  • the grooves are placed with their longitudinal axis being radially directed and that the grooves are placed with the same distance to their longitudinal axis measured on a circle with a centre being the centre of the bore.
  • a mixing space is provided between the periphery of the mixing disc and the inner surface of the wall of the mixing chamber, and in that the flexible means are placed in said mixing space.
  • the flexible means are free to move, and the space improves the mixing property of the construction.
  • the invention also relates to a vehicle or device comprising a spreading arrangement, said vehicle/device comprising a motor for rotating the spreading device, a container for containing and supplying the granular material and a second container for supplying the liquid.
  • the bundles of elongated flexible means are made in a polymer material such as polypropylene or PBT.
  • the mixing disc is made in a polymer material such as polypropylene.
  • the flexible means are arranged in several separated units placed on the periphery of the mixing disc, each unit being placed between the openings of the grooves.
