Abstract
The present invention relates to a device for treatment of material in a vessel, particularly for dispersion or homogenization of liquids, or for suspension of solids in liquids. The device comprises a treatment element that is rotationally mounted in the vessel and that has an essentially tubular configuration comprising two ends. The jacket of the treatment element has a plurality of cuts formed with sharp edges, which may be drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material. The shearing forces produce the desired treatment in the vessel.
Claims17
A device for treatment of material in a vessel (1), particularly for dispersion or homogenisation of liquids, or for suspension of solids in liquids, of the kind comprising a treatment element (10) that is rotationally mounted in the vessel (1), characterized in that the treatment element (10) essentially is of tubular configuration and is formed in a jacket (15) with a plurality of cuts (11) formed with sharp edges (12), which are drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material wherein said treatment element is enveloped by said material and at least one of the ends of the treatment element (10) is formed with an inwardly directed flange.
A device for treatment of material in a vessel (1), particularly for dispersion or homogenisation of liquids, or for suspension of solids in liquids, of the kind comprising a treatment element (10) that is rotationally mounted in the vessel (1), characterized in that the treatment element (10) essentially is of tubular configuration and is formed in a jacket (15) with a plurality of cuts (11) formed with sharp edges (12), which are drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material wherein said treatment element is enveloped by said material and the treatment element (10) has a barrel-shaped contour configuration.
A device for treatment of material in a vessel (1), particularly for dispersion or homogenisation of liquids, or for suspension of solids in liquids, of the kind comprising a treatment element (10) that is rotationally mounted in the vessel (1), characterized in that the treatment element (10) essentially is of tubular configuration and is formed in a jacket (15) with a plurality of cuts (11) formed with sharp edges (12), which are drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material wherein said treatment element is enveloped by said material, wherein the cuts are the meshes of a net formed by expanding a material, in which through-slits have been made, said slits forming said sharp edges.
A device for treatment of material in a vessel (1), particularly for dispersion or homogenisation of liquids, or for suspension of solids in liquids, of the kind comprising a treatment element (10) that is rotationally mounted in the vessel (1), characterized in that the treatment element (10) essentially is of tubular configuration and is formed in a jacket (15) with a plurality of cuts (11) formed with sharp edges (12), which are drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material wherein said treatment element is enveloped by said material and the treatment element (10) is fitted on a stirrer (7) having vanes thereon, said stirrer arranged to be driven via magnetic drive by a drive means (6) situated on the exterior of the vessel (1).
A device for treatment of material in a vessel (1), particularly for dispersion or homogenisation of liquids, or for suspension of solids and liquids, of the kind comprising a treatment element (10) that is rotationally mounted in the vessel (1), characterized in that the treatment element (10) essentially is of tubular configuration and is formed in a jacket (15) with a plurality of cuts (11) formed with sharp edges (12), which are drawn through the material in the vessel as the treatment element rotates, in order to transfer shearing forces to said material;
- wherein the cuts (11) are formed with shovel means (13), the mouths of which are all orientated in the direction of rotation (A) of the treatment element, said mouths being formed with sharp edges (14).
