A device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. The device comprises: a nozzle for dispensing the third material; a first container adapted to store a first ingredient material and mix the first ingredient material with a second ingredient material; a second container disposed within the first container, and moveable between a storage position in which a second ingredient material is stored in the second container and a mixing position in which the second ingredient material is moved to the first container; a mixer that longitudinally extends into the first and second containers; a handle alternatively coupled to the mixer to mix the first and second ingredient materials or to the second container to move the second container to a dispensing position to dispense the third material. During use, the first container is rotated causing the second container to move relative to the first container and the second material to flow into the first container for mixing. After mixing, the handle is uncoupled from the mixer and coupled to the second container to dispense the third material from the nozzle. Embodiments are also described herein for a method of making the device and a method of using the device.

A multi-stage mixer includes a multi-stage mixer inlet, a multi-stage mixer outlet, a first flow device, and a second flow device. The multi-stage mixer inlet is configured to receive exhaust gas. The multi-stage mixer outlet is configured to provide the exhaust gas to a catalyst. The first flow device is configured to receive the exhaust gas from the multi-stage mixer inlet and to receive reductant such that the reductant is partially mixed with the exhaust gas within the first flow device. The first flow device includes a plurality of main vanes and a plurality of main vane apertures. The plurality of main vane apertures is interspaced between the plurality of main vanes. The plurality of main vane apertures is configured to receive the exhaust gas and to cooperate with the plurality of main vanes to provide the exhaust gas from the first flow device with a swirl flow.

An exhaust gas aftertreatment device for a motor vehicle has an exhaust pipe and a mixing chamber arranged in the exhaust pipe to mix an exhaust gas stream with a reducing agent which can be introduced into the mixing chamber by a dosing device. The mixing chamber has a wall which is on the input side as viewed in a main flow direction of the exhaust gas stream through the exhaust pipe and in which a first inlet for the exhaust gas is formed. The first inlet extends in some regions in a lateral surface region of the input-side wall such that exhaust gas entering the mixing chamber through the first inlet can be set in a rotating motion inside the mixing chamber. The dosing device has an outlet device where a longitudinal axis of the outlet device is inclined towards the main flow direction of the exhaust gas stream.

The present invention relates to a method and device for emulsifying emulsion explosive: an oil phase and a part of a water phase having undergone split-flow enter a first stage coarse emulsion mixer; after mixing, the mixture together with a part of the water phase having undergone second stage split-flow enters a second stage coarse emulsion mixer; the obtained mixture together with a part of the water phase having undergone third stage split-flow enters a third stage coarse emulsion mixer for mixing; forming a coarse emulsion matrix after multiple stages of mixing, and finally completing emulsification after mixing in a multi-stage fine emulsion mixer. The method and device mix the water phase with the oil phase multiple times according to a desired ratio, thus greatly reducing the stored explosive, with no mechanical stirring or shearing, with no heat accumulation, and with low pressure, without requiring matrix pumping, thus enhancing safety.

An exhaust gas post-treatment apparatus comprises a first mixing chamber assembly and a second mixing chamber assembly. The first mixing chamber assembly comprises a first housing provided with a first mixing chamber, a gas inlet pipe, a first mixing pipe at least partially located in the first mixing chamber and a perforated pipe located in the first mixing pipe. The first mixing pipe includes a first pipe body located in the first mixing chamber and a second pipe body extending from the first mixing chamber, wherein a side wall of the first pipe body is provided with apertures and flow plates located in the first mixing chamber. In the axial direction of the perforated pipe, the perforated area of the perforated pipe fully covers the length of the flow plates. The second mixing chamber assembly includes a flow-guiding hood.

Methods and systems are provided for a mixer. In one example, a system may include a mixer arranged in a passage and configured to mix two dissimilar types of gases upstream of a device.

A nanobubble-producing apparatus includes a liquid vat provided with a bubble-containing-liquid inlet in an upper part thereof and a bubble-containing-liquid outlet in a bottom part thereof, a microbubble-containing-liquid supply unit to supply microbubble-containing liquid that contains microbubbles to the bubble-containing-liquid inlet of the liquid vat, an ultrasonic collapse unit to radiate ultrasonic waves to the inside of the liquid vat so that an ultrasonic collapse field in which the collapsing of the microbubbles with the ultrasonic waves is concentrated and nanobubbles are generated is formed at a location where the microbubble-containing liquid supplied into the liquid vat through the bubble-containing-liquid inlet flows downward, and a nanobubble-containing-liquid extraction portion where the nanobubble-containing liquid that contains the nanobubbles generated by the ultrasonic collapse unit is taken out of the liquid vat through the bubble-containing-liquid outlet.

Provided in one implementation is a method that includes introducing a volume of raw material into a chamber of a cavitation machine. The raw material can include a mixture comprising a powder and a solvent. The powder can have a first average particle size in the raw material. The method includes applying a hydrodynamic cavitation process to the raw material to produce a product material. The powder can have a second average particle size, smaller than the first average particle size, in the product material. The method includes causing the product material to exit the cavitation chamber and drying the product material to remove the solvent. Apparatus employed to apply the method are also provided.
