A mixing unit includes a mixing body having mixing elements that are stacked in a stacking direction and that extend in an extending direction in which the extending direction is perpendicular to the stacking direction. The mixing elements have a plurality of through holes to form a flow path therein, and are arranged such that part or all of the through holes in one of the mixing elements communicate with through holes in the adjacent mixing elements to allow fluid to be passed in the extending direction in which the mixing elements extend. The mixing unit may be employed in an agitation impeller or an adhesive dispensing unit.

A micro-bubble generator has an intake manifold, a casing threadingly connected to the intake manifold, a first air inlet channel defined between threads of the intake manifold and the casing, a booster located inside the casing and having a gap defined between the casing and the booster to form a second air inlet channel and to communicate with the first air inlet channel, a bubble generating tube located inside the casing and having a third air inlet channel defined between the end faces of the bubble generating tube and of the booster. The booster includes a first water inlet and a first water outlet having an inner diameter smaller than that of the first water inlet so that water velocity at the first water outlet is faster than that at the first water inlet, which forces ambient air to enter the bubble generating tube via air inlet channels and to be mixed with water in the bubble generating tube to generate bubbles. Bubbles are cut into micro-bubbles after passing through the cutter and exit the bubble exit.

A device and apparatus for mixing and dispersing a solid and a liquid are provided. The device includes a powder pulverizing mechanism fixedly connected to a main shaft. The powder pulverizing mechanism is located in a powder feed chamber. The powder feed chamber is provided with a powder feed port. A liquid feed chamber is arranged on an outer side of the powder feed chamber. The liquid feed chamber is provided with a liquid feed port, and the liquid feed chamber is provided therein with a dispersing mechanism fixedly connected to the main shaft. A lower portion of the liquid feed chamber and a lower portion of the powder feed chamber are separately in communication with an upper portion of a mixing chamber. The mixing chamber is provided therein with an impeller fixedly connected to the main shaft.

The disclosure generally refers to a continuous mixer, which can be used in the production of coated particles, such as proppants used in hydraulic fracturing techniques.

An apparatus for mass transfer between a liquid and a gas inside a rotor having a packing. The liquid is introduced at a center of the rotor and driven outward through the packing by centrifugal force generated by rotation of the rotor, and the gas surrounding the rotor is forced inward through the rotor by a pressure of the gas, counter to the liquid flow in the rotor. The packing inside the rotor is divided into individual packing segments that together form a circular disk. Each circular ring segment is formed by at least one structured packing comprised of a plurality of superimposed woven, knitted, mesh or lattice structured surfaces composed of metal, in particular sheet-metal strips, or plastic or glass fibers, to which the axis of rotation of the rotor runs perpendicular.

Biomass feedstocks (e.g., plant biomass, animal biomass, and municipal waste biomass) are processed to produce useful products, such as fuels. For example, systems are described that can convert feedstock materials to a sugar solution, which can then be fermented to produce a product such as a biofuel.

An apparatus and method are disclosed for mixing and pumping solids and fluids and includes use of a blender including: a casing defining a cavity; a drive shaft extending through a casing opening into the cavity; a slinger having an outer edge, a center, a bottom slinger surface, a top slinger surface, and a plurality of slinger blades extending upwardly from the top slinger surface, wherein the slinger is attached to the drive shaft, and wherein the height of the top slinger surface above the bottom slinger surface continuously increases from the outer edge to the center; and an impeller having a bottom impeller surface and a plurality of impeller blades extending downwardly from the bottom impeller surface, wherein the impeller is positioned below the slinger and is attached to the drive shaft.

A rotating mechanism of a handicraft is provided, including: a cover body for covering a water lamp handicraft; a support member, where an end is connected to the cover body, and an other end includes an outer rotating groove; a water stirring impeller, located between the cover body and the support member, a rotating body, sleeved on the support member and having an inner rotating groove corresponding to the outer rotating groove; and a ball ring, located between the outer rotating groove and the inner rotating groove, where the rotating body is rotatably connected to the support member through the ball ring.
