Abstract:
Die Erfindung betrifft ein Verfahren zum Betrieb eines Apparates (1) mit mindestens einer rotierenden Welle (5), wobei die mindestens eine rotierende Welle (5) Funktionselemente (7) aufweist, die auf in dem Apparat (1) zu verarbeitendes Material einwirken, wobei der Apparat (1) eine Einfüllöffnung (15) und eine Auslassöffnung (9) mit einer einstellbaren Unterkante (13) aufweist und Material kontinuierlich durch den Apparat (1) von der Einfüllöffnung (15) zur Auslassöffnung (9) gefördert wird, folgende Schritte umfassend: a) Messung von Belastungsdaten der mindestens einen rotierenden Welle (5) zur Bestimmung der Wellenbelastung, b) Absenken der Unterkante (13) der Auslassöffnung (9) und/oder Reduzieren der Menge an zugeführtem Material, wenn die Wellenbelastung eine vorgegebene Maximalbelastung überschreitet oder Verschieben der Unterkante (13) der Auslassöffnung (9) nach oben und/oder Erhöhen der Menge an zugeführtem Material, wenn die Wellenbelastung kleiner als eine vorgegebene Wellenbelastung ist.
Abstract:
The present invention relates to an apparatus for mixing a first fluid into a second fluid, which apparatus comprises: a housing (12) having a flow-through chamber (20) for said second fluid, a throttling body (70) in the flow-through chamber, and also inlet and outlet passages (30, 32) for said second fluid to and from, respectively, said flow-through chamber (20). In the invention, the throttling body (70) is arranged with elements (82, 90, 94, 96) which are able to displace said throttling body (70) between a position in which it blocks the inlet passage (30) and a position in which the inlet passage (30) is open. The apparatus is also provided with means (38, 44) for introducing said first fluid, preferably into, or immediately in front of, said inlet passage (30).
Abstract:
A constrictor valve can be associated with a conduit in fluid communication with a mixer to control a flow of cementitious slurry discharged from the mixer through the conduit. The constrictor valve can include a constrictor housing, a webbing constriction assembly, and a drive mechanism. The webbing constriction assembly includes a pair of rotatable members rotatably mounted to the constrictor housing and a plurality of webbing straps connected to the rotatable members and wrapped around the conduit. The drive mechanism includes a drive shaft and a gear assembly configured to rotate the rotatable members in opposing winding directions in response to the drive shaft rotating in a tighten direction to wrap the webbing straps tighter around the conduit to compress it and to rotate in opposing unwinding directions in response to the drive shaft rotating in a loosen direction to loosen the grip of the webbing straps on the conduit.
Abstract:
A throttled fluid mixing device comprises a valve having an axially extending valve casing (2) containing a disc-shaped valve member (3) located axially within said casing and arranged for axial movement relatively to a flared inner wall portion (2C) of said casing which is arranged to widen continuously in a direction away from its upstream end. Axial movement of the valve member (3) serves to throttle the flow of fluid through said casing, and the valve member (3) has, on its downstream side, one or more orifices (3C) from which a second fluid can be introduced into the valve casing (2) immediately on the downstream side of the valve member (3), whereby turbulent flow immediately downstream of the valve member (3) is effective to cause mixing of the two fluids. Preferably, the disc-shaped valve member has a domed or radiused frontal face, and, on its rear face, an annular recess (3A) located adjacent the rim of the disc and coupled to the orifice or orifices (3C).
Abstract:
A multifunctional mixer, including a rack, a container, a blender and a transmission, a round circular orbit is installed on the lower of rack, the bottom of a vertical cylinder contain is a cone-shaped bottom which is driven by a lifting device, thus it can automatically lift and fall, while transmission mechanism drives the blender to rotary, by transmission, the container component rotates in a reverse direction with the rotation direction of blender on the round circular orbit of rack, the blender is consisted of a number of blending rods fixed to a horizontal blending shelf, the rotation axis of blending shelf is eccentricity relative to the centerline of vertical cylinder container. The invention with blending rods of different structure has respectively follow functions: mixing, skinning, cleaning, polishing and dampening.
Abstract:
A gas-driven appliance comprises a jet pump (10) and a small burner in which a gaseous fuel (58) is mixed with air (60) by the jet pump (10) and the fuel/air mixture (62) is burnt. The fuel (58) flows through a variable-width regulating gap (34) provided on the upstream section of a valve element (14). A propelling nozzle (38) which forms an open jet is arranged on the downstream section of the valve element (14) and a collecting nozzle body (44) is arranged downstream of the propelling nozzle (38). An upstream front wall (46) of the collecting nozzle body (44) and a downstream wall (40) of the valve element (14) form a second variable-width regulating gap (54) through which the air (60) is entrained by the open jet. This measure makes it possible to vary the fuel/air mixture (62) in function of the operating mode of the appliance.
Abstract:
The invention relates to an apparatus for mixing a first fluid into a second fluid, which apparatus (A) comprises: a housing (1) having a flow chamber (39) for the said second fluid; a flow restrictor member (6) in the flow chamber; and means (18) for introducing the said first fluid into at least one gap (15, 16) between the flow restrictor member and those walls (5, 10) of the flow chamber (39) facing towards the flow restrictor member. The characteristic features of the invention are: that the flow restrictor member, in a plane transversely to the principal flow direction (31) of the second fluid, as well as the said flow chamber in the same plane, has the essential shape of a wedge; that between each of those two sides of the flow restrictor member which converge in a wedge shape and those walls of the wedge-shaped chamber facing towards the flow restrictor member there is a gap (15, 16); and that the said means (18) for introducing the said first fluid are disposed in the region of these two gaps.
