A mixer is adapted to include: a flow path forming member formed with an internal flow path; and an insertion member inserted into the internal flow path, in which: the inner circumferential surface forming the internal flow path in the flow path forming member or the outer circumferential surface of the insertion member is formed with a first groove and a second groove merging with the first groove and branching from the first groove, and the inner circumferential surface and the outer circumferential surface are fitted to each other; and the first groove and the second groove are formed as a mixing flow path for, between the flow path forming member and the insertion member, branching and merging fluid flowing from one side of the internal flow path and guiding the fluid to the other side of the internal flow path.

A production method for producing a particle mixture in which two or more types of particles are mixed, including a step of adding a first additive to first particles and mixing the first additive with the first particles using a first mixer and a step of introducing the two or more types of particles including the first particles mixed with the first additive and second particles into a blender container of a gravity blender, and mixing the two or more types of particles inside the blender container.

The fluoride tablet feeder device is a device for dissolution of fluoride tablets into a water stream. The device is specifically designed for the fluoride tablets disclosed and claimed by U.S. Pat. No. 10,485,738 titled Tablet for Fluoridating Potable Water, which is incorporated by reference. The crux of ideal dissolution of fluoride tablets in a flowing water supply is total immersion of the tablets, with water flowing around all tablet sides for even dissolution.

An exhaust mixer apparatus, emissions cleaning module, and a method of manufacturing the exhaust mixer apparatus is provided. The exhaust mixer apparatus comprises an exhaust conduit, a first exhaust mixer and a second exhaust mixer. The exhaust conduit is configured to extend in an elongate direction comprising an inlet and an outlet for transporting exhaust fluid. The first exhaust mixer comprises a plurality of elongate mixing blades each having a length extending in the elongate direction. The elongate mixing blades are connected together along at least part of their lengths and arranged about the elongate direction, each elongate mixing blade comprising an outer edge extending in the elongate direction. The elongate mixing blades are twisted along their lengths such that the outer edge of each elongate mixing blade is rotated about the elongate direction. The exhaust conduit is configured to locate the first exhaust mixer in an upstream location of the exhaust conduit. The second exhaust mixer is configured to impart a swirl on an exhaust fluid when in use. The second exhaust mixer is arranged in the exhaust conduit downstream and spaced apart from the first exhaust mixer in the elongate direction.

A system, method, and apparatus for oxygenation of a source of water, to increase the dissolved oxygen content of water. Aspects of the present invention harnesses and directs the power of water flowing through the system to extract oxygen present in air, rather than relying on the injection of gas or using other mechanical means. The water oxygenator is formed as an elongate cylindrical tube having a water inlet at a first end, a water outlet at a second end, and an air inlet proximal to the first end. The elongate cylindrical tube has an outer sidewall defining a mixing chamber within an interior cavity of the water oxygenator. The mixing chamber includes a plurality of baffles that are disposed in a spaced apart relation along a longitudinal length of the interior cavity.

A mixing and dispensing device and method. In particular, the device used by the applied method reduces the risk of chlorine gas formation while providing a stable, effective and safe disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device includes a highly concentrated disinfectant and dilutes the concentrate through the device while simultaneously mixing the concentrate with a dilute solution of an organic acid. The two diluted solutions are mixed without production of chlorine gas and to a level of safety before being dispensed to produce the stable, effective and safe neutral pH sodium hypochlorite solution disinfectant in the form of a hypochlorous add and sodium hypochlorite mixture. The mixing and dispensing device can be in the form of a kit for retrofitting into institutions or isolated, remote areas in need thereof or for off the shelf use in the home.

A device and a method for dispersing at least one substance in a fluid is disclosed. The device includes a process housing with a rotor, a fluid supply, a feed line for the at least one substance to be dispersed having at least one outlet opening, as well as a product outlet. The rotor brings about an axial delivery of a supplied fluid at least in some sections. Furthermore, the rotor brings about a radial delivery of the supplied fluid at least in some sections.

The invention generally relates to a mixing device. In certain embodiments, devices of the invention include a fluidic inlet, a fluidic outlet, and a chamber, the chamber being configured to produce a plurality of fluidic vortexes within the chamber.

A rotary machine for acting on a process fluid includes an impeller, a shaft, a drive, a seal and a flush casing. The impeller acts on the process fluid and is mounted on the shaft. The drive is connected to the shaft and rotates the shaft and the impeller about an axial direction. The seal has a sealing element sealing the shaft during rotation of the shaft. The flush casing receives a flushing fluid for flushing the sealing element, and delimits an annular flush chamber extending about the sealing element. The flush casing includes a bushing surrounding the sealing element and delimits a radial leakage gap arranged between the sealing element and the bushing. The bushing delimits an axial leakage gap between the impeller and the bushing, and the width of the axial leakage gap in the axial direction is adjustable.

An atomizing system is provided to connect a liquid supply zone and a gas supply zone. In the atomizing system, a first pipeline is connected between the liquid supply zone and a first treatment tank, a second pipeline is connected between the first treatment tank and a second treatment tank, a third pipeline is connected between the gas supply zone and the second treatment tank. The end of each of the nozzles is connected to the other end of the third pipeline. The liquid supplied from the liquid supply zone is flowed into the second treatment tank through the second pipeline, the gas supplied from the gas supply zone is flowed into the second treatment tank through the nozzles, so that the liquid contacts the gas in the second treatment tank to produce the atomized liquid.
