    摘要: The sand mixing device (1) has a mixing bowl (2) arranged stationarily on a support frame (3) and including a peripheral side wall (4) and a bottom wall (5). A central mix- ing tool (6) is arranged rotatably about a central mixer axis (7) of the mixing bowl and has a number of blades (8) extending along the bottom wall to the peripheral side wall. The mixing bowl is arranged in an inclined position on the support frame so that the central mixer axis is inclined at an angle to the vertical. A first cross-sectional plane extending through the mixing bowl and including both the central mixer axis and a horizontal line extending in a plane defining the bottom wall divides the mixing bowl into a lower part and a higher part. At least one peripheral mixing tool (9, 11) is arranged in the lower part of the mixing bowl.

    摘要: A method of reclamation of the used foundry sand, especially with an inorganic geopolymer binder system, wherein the reclamation occurs in batches so that friction elements located on two shafts rotate inside each dose of the used sand, wherein the reclamation is done by rotation of the impact bars (3) in the used sand moving in the fluidized bed, where the volume ratio of impact bars (3) to the volume of the batch of the used sand is in the range from 0.03 to 0.10, wherein the air passes through the layer of the sand with the velocity which ranges from 1,5 to 4 times the threshold velocity of fluidization, wherein for quartz sands the fluidization threshold speed is equal to 0,17 m/s. An equipment for performing the method of reclamation of the used foundry sand according to the claims 1 to 3, comprising a container casing (1), in which shafts (2) provided with impact bars (3) are arranged in a certain distance between them, wherein the container casing (1) has in its ground plan section shape of an oval, wherein spaced from its bottom there is a permeable bottom (6) of the fluidized bed attached on a carrier (5), and further, the container casing (1) is in its upper part provided with a dosing opening (8), wherein in its lower part has the container casing (1) the unloading opening (9) and the inside of the container casing (1) is provided with a wear-resistant lining (11), furthermore, in the container casing (1) there is arranged a pair of vertically oriented shafts (2) on which cylindrical impact bars (3) are attached.

In der Mischkammer (2) befindet sich ein über den Querschnitt der Mischkammer (2) reichendes Mischwerkzeug (3), welches während des Mischvorganges axial über die Länge der Mischkammer (2) vorzugsweise mehrfach verstellbar ist. Bevorzugt ist die Mischkammer (2) vertikal angeordnet und hat an ihrem unteren Ende eine Entleerungsöffnung (4), während am oberen Ende ein Deckel (9) mit einfüllöffnungen für die Mischungsbestandteile angeordnet ist. Durch die mehrfache Axialbewegung des Mischwerkzeuges (3) innerhalb der Mischkammer (2) wird nicht nur in jedem Querschnitt eine Durchmischung erzielt, sondern das Material auch in axialer Richtung durchmischt.

    摘要: There are provided a device and a method allowing that the surface of an admixture in a stirring tank pressed by a packing device is smoothed with a simple structure whereby a casting mold is precisely molded. A mold-making device includes a stirring device 3 that has a stirring tank 1 and stirring blades 2 and stirs a particulate aggregate and an additive(s) to yield an admixture M, a forming mold 4 that molds the admixture M into a predetermined shape, and a packing device 5 that compresses a surface of the admixture M within the stirring tank 1 and packs it into the forming mold 4. The stirring blades 2 are configured in a lattice pattern by a plurality of horizontal members 21 and a plurality of vertical members 22. A distal end of a rotating drive shaft 23 is bonded to the top edge of the stirring blades 2, and the rotating drive shaft 23 is configured so that it is not immersed into the admixture M. Scrapers 29 for smoothing out the surface of the admixture M are provided on the bottom of the stirring blades 2.

    摘要: The present invention relates to a mixing device comprising a preferably rotating container for holding a mixture, at least one mixing tool arranged inside the container, and a heating device for heating the mixture. In order to provide a mixing device of the type mentioned above which permits the fastest possible heating of the mixture, preferably also to temperatures above 200°C, it is proposed that the container be composed at least partially of an electrically conductive material and the heating device comprise at least one coil which can be excited by an alternating electric field and which is arranged in such a way that eddy currents are produced in the electrically conductive material of the container by the magnetic field change that arises when the current flow is changed.
