A stirring member (90) for an industrial stirrer, in particular for a stirring rod arrangement, for connecting to a stirring mechanism combinable with a container for receiving liquids, wherein the container comprises a filling opening closable with a lid for filling the container in an upper bottom wall, wherein the stirring member is connectable to a rod-shaped stirring member carrier of the stirring rod arrangement, wherein the stirring member comprises a bearing end (91) and a stirring member end (94) connected to the bearing end (91) via a link (92) and having a flow tube (93), wherein the flow tube comprises a tube wall, wherein the flow tube comprises an annularly formed accumulating surface (95) at its flow inlet cross section, wherein the accumulating surface comprises at least one circular ring sector (96) which is inclined with respect to an inflow plane of the flow inlet cross section.

A powdery-material feeding device is configured to feed a powdery material to a compression-molding machine configured to obtain a molded product by filling a die bore with the powdery material and to compress the powdery material with punches. The powdery-material feeding device includes a detector configured to detect a biologically-originated foreign matter mixedly contained in the powdery material to be fed to the compression-molding machine, and a controller configured to control to remove the powdery material mixedly containing the biologically-originated foreign matter detected by the detector to avoid feeding of the powdery material mixedly containing the biologically-originated foreign matter to the compression-molding machine, or to control to stop the feeding of the powdery material to the compression-molding machine.

A fluid mixing system includes a container, such as a flexible bag, bounding a compartment. A flexible drive line is disposed within the compartment, the drive line having a first end rotatably connected to a first end of the container and an opposing second end rotatably connected to a second end of the container. At least one mixing element, such as an impeller, can be coupled with the flexible drive line. Rotation of the drive line facilitates rotation of the impeller within the container.

The present invention relates to an apparatus comprising a reactor body to which gas and water are supplied to create a gas hydrate; an upper cover which is engaged to an upper portion of the reactor body, a scraper mounted rotationally within the reactor body, and a motor for providing a driving force to the scraper. It is possible to remove gas hydrate particles attached to at least one of an inner surface of the reactor body and an inner surface of the upper cover, by a rotary driving of the scraper. According to the invention, it is possible to prevent a material hindering a heat transfer by attaching on a wall surface of the reactor, through a process of scraping out gas hydrate particles, when the scraper which is rotationally driven about a center axis of the reactor is close to the inner surface of the reactor.

A pug mill having a housing and a cantilevered shaft extending through the housing includes, in seriatim, a vacuum chamber, a wall, a mixing chamber and a reduction cone. A communication port about the shaft is positioned in the wall between the vacuum chamber and the mixing chamber. Vacuum can be maintained within the mixing chamber by air passing through the port. An auger associated with the shaft forces clay toward the reduction cone. This creates a seal for maintaining vacuum within the mixing chamber and extrudes cylindrical blocks of conditioned clay without significant air bubbles. A deflection plate rotating with the shaft and a spiral element about the shaft keep the communication port clear. The shaft is eccentrically mounted. The dividing wall is removable.

A container (1) for a viscous liquid, in particular a colorant for paint, may comprise a stirrer (2) having a rotatable shaft (3) and a plurality of paddles (4) connected to the shaft (3). At least one of the paddles (4) and/or the connections (5) between the paddles (4) and the shaft (4) is flexible.

A radially conveying stirring device with at least one stirring element hub configured to rotate about a rotational axis, with at least one stirring blade and with at least one carrier arm connecting the stirring blade to the stirring element hub, wherein there is at least one half-line which starts from the rotational axis, goes through a center of mass of a connecting surface area of the carrier arm to the stirring element hub and is free from intersection points with the stirring blade, and wherein the stirring blade features at least one beveling dividing the stirring blade into at least two stirring blade sections, wherein the carrier arm is embodied at least substantially L-shaped, wherein the beveling is arranged at least substantially in parallel to the rotational axis.

This mixing machine comprises a mixing head that attaches to a container, forming a closed mixing receptacle. The head is pivotably supported in a frame such that the closed mixing receptacle can pivot to perform the mixing. The mixing head also has a rotationally driven tool which cleans the bottom of the head, supplying a low-energy transport stream for material to at least one second tool carried by the head. The second tool performs the mixing and is located inside the movement path of the bottom-cleaning first tool. The first tool has a scoop positioned in the direction of rotation of the tool with its edge facing in the direction of rotation and outward in the radial direction. The first tool comprises a first scoop section, a second, wall-cleaning scoop section and a recess open toward its closure more remote from the wall through which the second tool passes during rotation of the first tool.

The invention relates to an agitator device having a static unit and a rotational unit which is in the form of an agitator shaft and, in an assembled state, forms together with the static unit at least one common fluid channel for a fluid. It is proposed that a flow cross-section of the fluid channel, viewed along a main course of flow, is at least substantially constant at least in a coupling region between the static unit and the rotational unit.

A radially conveying stirring device with at least one stirring element hub configured to rotate about a rotational axis, with at least one stirring blade and with at least one carrier arm connecting the stirring blade to the stirring element hub, wherein there is at least one half-line which starts from the rotational axis, goes through a center of mass of a connecting surface area of the carrier arm to the stirring element hub and is free from intersection points with the stirring blade, and wherein the stirring blade features at least one beveling dividing the stirring blade into at least two stirring blade sections, wherein the carrier arm is embodied at least substantially L-shaped, wherein the beveling is arranged at least substantially in parallel to the rotational axis.
