The invention relates to a mixing device (10), particularly for producing a suspension consisting of at least one respective liquid component and solid component. The mixing device comprises a mixing chamber in which a shaft (12) is rotationally arranged, said shaft determining an axis of rotation (A). Several mixing blades (16) are fixed to the shaft (12), rotating with said shaft (12) in a preferred direction of rotation (R). At least two of the mixing blades (16) have a wedge-shaped base body (24) when see from a cross-sectional point of view, said base body extending from the shaft in a radially outward manner, and a mixing blade head (28) which is also wedge-shaped and which is connected to the free end of the base body (24). The wedge tips (26 and 30) of the base body (24) or mixing blade head (28) are both oriented in the preferred direction of rotation (R) of the shaft and the mixing blade head (28) widens out more strongly in an axial direction than the base body (24), starting from the associated wedge tip (30). As a result a transition area (36) is formed between the narrower base body (24) and the broader mixing blade head (28) on at least one side of the base body (24). Said transition area (36) is inclined in relation to the axis of rotation (A) of the shaft in such a way that items to be mixed, contained in the mixing chamber, are transported in an inner direction towards the shaft (12) when the shaft (12) rotates in the preferred direction of rotation (R).

A mixer having i) a vessel defining a mixing chamber surrounded by boundary walls for receiving a mixture containing lumps therein, ii) a plurality of mixing blades, and iii) a driving mechanism supporting the mixing blades in the mixing chamber for mixing motion relative to the vessel so as to mix the mixture within the mixing chamber of the vessel, further includes at least one lump conditioning blade. The lump conditioning blade is supported by the driving mechanism such that the lump conditioning blade is movable in a working direction along a respective one of the boundary walls with a working edge of the blade being maintained at a prescribed space from the boundary wall which is effective to reduce a lump size of the lumps in the mixture as the mixture passes between the working edge of the lump conditioning blade and the boundary wall.

It is an object of the present invention to provide a wet mixing apparatus (20) and a wet mixing method capable of mixing a raw material mixture uniformly while preventing adherence of a wet mixture to the inner wall of the mixing apparatus (20). The wet mixing apparatus (20) according to the present invention comprises: a disc (22) having a circular platelike structure, equipped with a vertically placed rotary shaft member (21) as a central axis and having a plurality of agitation blades (25) provided on the side face thereof; and a casing (26) provided with a raw material feeding port (28a,28b) and a mixture discharging port (29), wherein the raw material feeding port (28a,28b) is disposed above the disc (22) and the mixture discharging port (29) is disposed below the disc.

Zum Aufbereiten luftporenreicher Putze oder Mörtel wird in einer Mischkammer (30), weicher ein Vorratsbehälter für das Trockengut vor- und eine Absaugvorrichtung für das Mischgut nachgeschaltet wird, ein grobkörniger bis pulverförmiger Trockenfertigmörtel mit einer Flüssigkeit und/oder einem Schaumgut kontinuierlich gemischt, wobei die Mischkammer durch eine mechanische Vorrichtung in Zusammenwirkung mit dem Trockengut gegen Luftaustritt durch die Trockengutzuführung gesperrt wird und teils mit dem Trockengut, das durch unter geringem Überdruck stehende Luftpolster durchsetzt ist, und teils mit dem Mischgut gefüllt gehalten wird, während die Trockengutnachförderung mindestens gleich groß bleibt wie die Entnahme des Mischgutes durch die Absaugvorrichtung.
摘要:
There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.
