The present invention discloses a device for mixing a mixture material comprising at least two different phases where at least one first phase is in powdered form, said device comprising at least two separate inlets where a first inlet is intended for powder and a second inlet is intended for a second phase not being a powder, wherein the device further comprises an outlet and a mixing chamber with an agitator, wherein the mixing chamber comprises a mixing zone being that part of the mixing chamber in which the mixture material is being actively mechanically influenced to obtain mixing, and wherein said at least two separate inlets each involve any type of geometrical narrowing of their cross-sectional areas up to the mixing zone, and wherein the mixing zone further comprises any type of expansion of the cross-sectional area in a flow direction of the mixture material.

A device for mixing at least two fluid to pasty substances has a housing (2) with at least two openings (5, 6) for feeding the substances and with a discharge opening (8), a mixing element (3) which can rotate in the housing (2), which mixing element (3) can be displaced in the direction (17) of its axis (7) in relation to the housing (2) in order to adjust the size of a gap (18) between a conically tapering part (14) of the mixing element (3) and a likewise tapering region (15) of the housing (2) in order to adjust the shear rate in the region of the gap (18). The mixing element (3) has a region (9) in which annular ribs (11) are provided which project from the mixing element (3) and which engage between adjacent annular ribs (12) which project from the inner surface (10) of the housing (2).

The invention relates to a generator and its operation and use for generating toroidal and spatial vortices in a liquid. It comprises a rotationally symmetrical stator housing with an inlet opening and an eccentric outlet opening. It further comprises a rotor rotatably arranged in the stator housing with radially outwardly extending channels in constant fluid connection to the inlet opening. The rotor comprises a rotor disc, radially outside of the rotor with a side surface with inner notches in fluid connection to the rotor channels. The stator housing comprises a stator disc comprising a side surface with stator notches. When these notches face each other due to rotation of the rotor disc, a periodical liquid flow from the inner notches to the stator notches is formed and toroidal vortices are generated in the portioned liquid by shear stress as the portions of liquid move back and forth in the notches.

In the case of a rotor (109) for a device for mixing powder and liquid, which device has a stator which interacts with the rotor (109), at least some shear blades (124) are of wedge-shaped form and are inclined with one face side (233) in a flow direction (239). This has the result, in the case of an effective diversion at side walls (227) situated at the front in a flow direction (239), of an intense shear action at the face sides (233) and of a relatively low risk of formation of deposits and adherent accumulations on the side walls (230) situated at the rear in the flow direction (239).

A mixing unit for mixing a flow of liquid product is provided. The mixing unit comprises a stator forming a hollow sleeve, and a rotor having a circular displacement plate with two opposite sides, wherein at least one side has at least two chambers formed by a plurality of vanes extending in a direction being parallel with a longitudinal axis of the stator, wherein the rotor is arranged within the stator for rotating liquid product arranged in said chambers relative the stator. The displacement plate is tilted relative a longitudinal axis of the stator such that said at least two chambers have different volumes, and a side wall of the stator has at least one exit area comprising at least one through hole for allowing liquid product to exit the stator.

Provided is a pulping device. The pulping device includes a housing, a drive shaft, and an impeller assembly. The housing defines a cavity. The impeller assembly is disposed in the cavity and is configured to be driven to rotate by the drive shaft. A bottom surface of the impeller assembly is disposed opposite to an end surface of the housing, and one of the bottom surface of the impeller assembly or the end surface of the housing is provided with an annular protrusion, and the other one of the bottom surface of the impeller assembly or the end surface of the housing defines an annular groove matching the annular protrusion, and an interference-proof clearance is defined between an outer wall of the annular protrusion and an inner wall of the annular groove.

A membrane/electrode assembly of a fuel cell using a film obtained by molding a mixture in which a synthetic resin and a solvent are mixed with fullerene nanowhisker/nanofiber nanotubes supporting a catalyst or including a catalyst in fullerene crystals, wherein the fullerene nanowhisker/nanofiber nanotubes are obtained by uniformly stirring and mixing a solution containing a first solvent having fullerene dissolved therein, and a second solvent in which fullerene is less soluble than that in the first solvent, in a thin film fluid formed between processing surfaces arranged to be opposite to each other so as to be able to approach to and separate from each other, at least one of which rotates relative to the other, and the resultant fullerene nanowhisker/nanofiber nanotubes are heated at 300 C. to 1000 C. in a vacuum heating furnace.

A fluid treatment device with a new configuration is provided. The fluid treatment device is provided with an upstream treatment unit defined by treatment surfaces that rotate relative to each other, and a downstream treatment unit arranged downstream of the upstream treatment unit. The upstream treatment unit is configured such that, by passing the fluid to be treated into an upstream treatment space defined by the treatment surfaces, the fluid to be treated is subjected to upstream treatment. The downstream treatment unit is provided with a downstream treatment space which performs the function of retaining and mixing the fluid to be treated by means of a labyrinth seal. An upstream outlet of the fluid to be treated from the upstream treatment unit opens into the downstream treatment space, and the downstream treatment space is configured to use the labyrinth seal to perform the function of controlling retention time. The downstream treatment space is provided with narrow seal spaces, and retention spaces arranged upstream of the seal spaces and wider than the seal spaces, and the upstream outlet opens to a retention space.
