摘要:
The present invention relates to a mixer for concrete and similar mixtures, of the type provided with a rectangular mixing tank (2), on whose lateral walls (4) the ends of two counter-rotating parallel mixing shafts with horizontal axis are fitted, it being provided that each end of each shaft is coupled with a geared motor (5) of standard size and power located externally on the bearing wall (4) of the tank (2).

The invention relates to a two-shaft compulsory mixer (1) whose mixing tools (4) are situated on two parallel mixer shafts (3a, 3b) in such a way and whose mixer shafts (3a, 3b) are also synchronised in such a way that with each rotation of the shafts (3a, 3b), the mixing tools (4) of both mixer shafts (3a, 3b) run from bottom to top through the horizontal line between the shafts (3a, b), axially adjacent to each other, in pairs, successively. In this way, the mixing tool pairs produce essentially continuous formations (9) as they pass through the area between the mixer shafts (3a, 3b), said formations emerging in a vertical direction between the two shafts (3a, 3b) from bottom to top. This significantly reduces the mixing times for a particular mixing quality compared to known two-shaft compulsory mixers with an identical number of middle mixing planes (5a-5h).

A mixing axis (1, 2) of a dual axis mixer for concrete mix, said mixing axis comprising several mixer elements attached to the mixing axis, said mixer elements including a mixing shaft (3) protruding substantially radially from the mixing axis, and at least one mixer blade (4) attached to the outer end of the mixing shaft, so that on that section of the mixing axis (1, 2) of the dual axis mixer that is located in the mixing tank, mixer elements are attached at nine successive mixer element fastening points (A-I), so that in the first, second and last fastening point (A, B and I), the total area of the mixer blades (4, 4') connected to a single fastening point is substantially four times as large as the total area of the mixer blades (4) connected to a single fastening point in the third, fourth, sixth and eighth fastening point (C, D, F and H). The invention also relates to a dual axis mixer provided with a described mixing axis.

A method for producing a ceramic honeycomb filter by blending a starting material mixture comprising a ceramic material, a molding aid and a pore-forming material under a pressure of 0.12-0.5 MPa in a pressure kneader to form a moldable material for a honeycomb extrudate.
摘要:
The present invention refers to a mixer for concrete, mortar and similar materials, provided with a parallelepiped tank in which two mixing shafts are horizontally mounted in parallel, which rotate inside basically cylindrical chambers, with a longitudinal overturned V-shaped profile in intermediate lower position, whose continuity is interrupted by the presence of a small central rectangular trap, with a hopper fixed in lower external position on the tank and provided with an upper mouth slightly larger than the length of the trap; it being also provided that the trap is equipped with a tilting lid to guarantee closing and opening by means of a suitable actuator.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum kontinuierlichen Mischen von lehmhaltigen Stoffen und Materialien mit lehmähnlichen Mischverhalten mit Wasser. Die Vorrichtung weist zunächst im unteren Bereich eines Vorrats- und Mischbehälters 1 eine Dosier- und Austragswelle 6 auf, die das mit dem Wasser vermischte Mischgut aus dem Vorrats- und Mischbehälter 1 austrägt und einer Fördereinrichtung 18 (Pumpe) zuführt. Erfindungsgemäß ist oberhalb der Dosier- und Austragswelle 6 zumindest eine Seitenwelle 9 angeordnet, die das Mischgut permanent auflockert, durchmischt und in Bewegung hält. Über eine Wasserzuführeinrichtung wird dem Mischgut geregelt Wasser zugeführt. Der Austrag von mit Wasser vermischtem Mischgut und die Zufuhr von Wasser sind so aufeinander abgestimmt, dass im unteren Bereich des Vorrats- und Mischbehälters ein Lehm-Wassergemisch mit gleichbleibender Konsistenz gebildet wird, dessen Höhenlinie 20 oberhalb der zumindest einen Seitenwelle liegt. Oberhalb der Höhenlinie 20 des Sumpfbereiches befindet sich trockenes Mischgut, welches entsprechend dem Austrag durch die Dosier- und Austragswelle nachrutscht.
摘要:
The present invention relates to a mixer for concrete and similar mixtures, of the type composed of a parallelepiped tank (2) internally provided with one or more mixing shafts (3), each of them driven into rotation by a corresponding motor unit (UM) in external position with respect to the tank (2), which comprises, with the necessary connections, an electric motor (4), a gear motor (6) and an intermediate gear (7) interfaced with the end of the corresponding mixing shaft (3), characterised by the fact that the electrical motor (4) and the corresponding gear motor (6) of each motor unit (UM) are fixed to a single bearing frame (8) that is hung to the border of the tank (2) by means of one or more hinges (9).
