Abstract:
A concrete mixer (10) includes a rotatable vessel (12) and a rotatable inlet cone (16). The rotatable vessel (12), such as a drum, is configured to mix concrete material upon rotation of the vessel (12). The inlet cone (16) is configured to transport concrete material and/or concrete making materials, into the vessel (12) through a vessel axial opening (13) upon rotation of the inlet cone (16). The inlet cone (16) is received at least partially within the vessel (12) via the vessel axial opening (13), wherein the arrangement of the vessel axial opening (13) and the inlet cone (16) is configured to prevent fluid communication of concrete material from the vessel (12) into the inlet cone (16) in a loading configuration and in a discharging configuration.
Abstract:
A mixing unit comprising a frame, a rheology control portion, and a high-volume solids blending portion. The rheology control portion comprises means for receiving a first material from a first transfer mechanism, a dispersing/mixing system connected with the frame, and a first metering system to meter the first material from the first material receiving means to the dispersing/mixing system. The dispersing/mixing system disperses/mixes the metered first material with a fluid to form a first fluid mixture. The high-volume solids blending portion comprises means for receiving a second material from a second transfer mechanism, a solids blending system connected with the frame, and a second metering system to meter the second material from the second material receiving means to the solids blending system. The solids blending system blends the metered second material with the first fluid mixture to form a second fluid mixture.
Abstract:
The present invention relates to continuous dry particulate matter injection device (1), and more in particular to a device for use in a fertigation application in which a soluble matter, such as a fertilizer, is suspended and/or dissolved into the irrigation water in order to use the irrigation system and irrigation water as a delivery system for the soluble matter, in particular a soluble fertilizer. To this end, the device comprises at least one feed device (2), suitable for feeding particulate matter, and connected, by a first connection pipe (3), to the top of a vertically positioned slurry mixing chamber (5), located under the first connection pipe (3), and a pressurized mixing tank (12), connected to the bottom of the slurry mixing chamber (5) by a second connection pipe (8). The device is operated in a continuous cycle.
Abstract:
An exemplary system for dispensing liquid and solid materials can comprise a tank; one or more liquid feeders configured to dispense one or more liquids into the tank; a powder hopper comprising a powder inlet, a powder outlet, and a valve configured to open and close the powder outlet, the powder outlet being coupled to the tank; one or more powder feeders coupled to the powder inlet of the powder hopper; a first scale configured to measure the mass of powder dispensed into the powder hopper; a second scale configured to measure the mass of the liquids dispensed into the tank; and a control system configured to control the dispensing of liquids and powders based at least in part on the mass measurements from the first and second scales.
Abstract:
The invention relates to a method and an arrangement for admixing powdered substance to heated liquid in a mixing vessel (11). The powdered substance is fed into the mixing vessel via a powder inlet (16) provided in the upper part of the mixing vessel and is made to fall down into heated liquid in the mixing vessel in order to be mixed with this liquid. Dry heated air or other dry gas is blown into the upper part of the mixing vessel above the surface of the heated liquid via one or more gas inlets (25) provided in the mixing vessel in order to form a volume of dry hot air or other dry gas in upper part of the mixing vessel in the area of the powder inlet and thereby prevent vapour from the heated liquid in the mixing vessel from rising to the powder inlet.
Abstract:
A device and method are provided for manually actuated dispensing of a particulate confection from a selected confection hopper into a dispensing stream of soft frozen dessert. The device includes a plurality of confection hoppers with corresponding confection outlets, a manual actuator operatively connected to a dispensing member that cooperates with the confection outlet to dispense only a controlled amount of confection from the corresponding hopper into a confection conduit each time the actuator is actuated, and mixing means for substantially uniformly mixing the controlled amount of confection into a serving amount of the soft frozen dessert as the dessert is dispensed into a serving receptacle.
Abstract:
Die Erfindung betrifft eine Mörtelmischpumpe (10) mit einer motorgetriebenen Förderschnecke (14) zum Einführen von zu vermischendem Material in eine Mischkammer (18), die mit einer Auskleidung (52) aus Gummi oder Kunststoff versehen ist, zumindest im Wesentlichen koaxial zur Förderschnecke (14) angeordnet ist und der durch eine oder mehrere Flüssigkeitseinspritzdüsen Flüssigkeit zuführbar ist, wobei in der Mischkammer (18) ein zur Drehung mit der Förderschnecke (14) bestimmtes Mischorgan (36) zum Vermischen des in die Mischkammer (18) geförderten Materials mit der Flüssigkeit aufgenommen ist, und wobei das von der Förderschnecke (14) entfernte Ende der Mischkammer (18) von einem zur Verbindung mit einer Pumpe (22) bestimmten Pumpenflansch (20) begrenzt ist. Zur Verbesserung des Gesamtbetriebsverhaltens, insbesondere zur Vermeidung jedweder Materialablagerung, und zur Vereinfachung der Reinigung ist die Förderschnecke (14) in einem Trichter (12) zum Einfüllen des zu vermischenden Materials angeordnet, ist die Mischkammer (18) ein vom Trichter (12) und Pumpenflansch (20) separates, mit dem Trichter (12) verbundenes Bauteil, steht die Auskleidung (52) der Mischkammer (18) in unmittelbarem Kontakt mit dem Trichter (12) und mit der Oberfläche des Pumpenflansches (20), und ist eine Mehrzahl von Flüssigkeitseinspritzdüsen (66) in einem Düsenträger (60) aufgenommen, der in einer Aussparung der Auskleidung (52) zumindest annähernd bündig mit der Innenfläche der Auskleidung (52) angeordnet und durch von außerhalb der Mischkammer (18) zugängliche Befestigungsmittel lösbar befestigt ist.
Abstract:
A transport device has a screw conveyor (3) rotative around its longitudinal axis and arranged in a housing (6) having a filling opening (7) and a discharging opening (8). In a partial section of the housing (6), the screw conveyor (3) has a different pitch. An enlarged space (9a-d) for relatively large components of the products to be transported may be arranged between the screw conveyor (3) and the housing (6, 6a-d).
Abstract:
In accordance with presently disclosed embodiments, systems and methods for using containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle of a blender are provided. A transportation unit may deliver one or more containers of bulk material to the well site, where one or more conveyors may deliver the containers to a location proximate the blender receptacle. A chute may extend from the bottom of each container to route bulk material from the one or more containers directly into the blender receptacle. Since the transportation unit is able to unload the containers of bulk material without pneumatic transfer, the containers may enable a cleaner and more efficient bulk material transfer at the site.
