An exhaust aftertreatment system for an internal combustion engine includes an outer casing defining an exhaust flow path for exhaust gases from the internal combustion engine, a selective catalytic reduction unit provided in the exhaust flow path for reducing nitrogen oxides, a urea dosing device for adding urea to the exhaust flow upstream of the selective catalytic reduction unit, and a rotatable mixer device for mixing the urea with exhaust gases upstream of the selective catalytic reduction unit. The exhaust aftertreatment system further comprises an air inlet valve provided upstream of the mixer device for introducing air into the exhaust flow path, and an electric motor arranged for rotating the mixer device to create a suction of air into the exhaust flow path via the air inlet valve.

The present disclosure relates to a mixer for drawing and mixing a solid product, such as a powder, with a liquid from a tank. The mixer includes a drawing wand which has a drawing tip suitable for drawing the product and a mixing vat which has a rotation shape delimited by a side wall. The discharge tip of the drawing wand leads into the top of a vat and injects the product into the vat. In one form, the mixer includes a hydraulic circuit designed to circulate the liquid between the tank and the vat. The circuit includes at least one injection duct having at least one injection nozzle that leads into the top of the vat so that the liquid from the tank flows over the side wall of the vat.

A bulk cargo blending hopper has a hollow interior volume that is selectively communicated with a source of vacuum pressure. A first conduit has a first end that is connected to the housing of the hopper and communicates with the interior volume of the housing of the hopper. An opposite second end of the first conduit is configured for communication with a source of bulk cargo that is separate from the hopper. A second conduit has a first end that is also connected to a portion of the housing of the hopper and communicates with the interior portion of the housing. A second end of the second conduit is also connected to a portion of the housing of the hopper and communicates with the interior volume of the housing of the hopper.

A device mixes bone cement and stores parent components of the bone cement. The device has a cartridge comprising an interior, that is closed on one side by a movable delivery plunger, a receptacle comprising side walls for receiving a monomer liquid container that are closed at least in some regions. The receptacle has at least one deformable closed side wall, a screen and/or a filter arranged below the receptacle so that the contents of the opened monomer liquid container flow through the screen and/or the filter. The device further has a connecting line through which the monomer liquid is to be routed into the interior of the cartridge, a hollow cylinder which is connected to the connecting line and which is connected to the receptacle by way of a fluid connection so that the hollow cylinder is arranged in a fluid line between the receptacle and the interior of the cartridge. A pump plunger is arranged in the hollow cylinder, which is axially displaceable in the hollow cylinder, and an opening device, which is movably mounted against the deformable side wall of the receptacle. The opening device extends into the hollow cylinder, wherein, by pressing the pump plunger into the hollow cylinder, the opening device is to be pressed against the deformable side wall of the receptacle so that the deformable side wall deforms such that a monomer liquid container located in the receptacle is to be opened by the pressure of the opening device.

A continuous chemical process is modified to allow parts thereto to be processed one quantum of matter at a time. This offers precision and efficiency beyond what is possible with the continuous mode. This Quantum Fluid Operation (QFO) is applied to basic unit operations: mixing, reacting, separating.

An analysis system may perform operations on an analyte that may be combined with multiple regents prior to being introduced into a flow cell. The instrument may include a volume into which the reagents to be combined with the analyte are aspirated one-by-one. The volume may be formed as a serpentine channel in a valve manifold associated with sippers for aspirating the reagents. The reagents may then be mixed by cycling a pump to move the reagents within the mixing volume or channel. For this, the reagents may be aspirated from a recipient into the volume or channel, ejected back into the recipient, and this process may be performed repeatedly to enhance mixing.

A grain and flour supply apparatus is provided, including a holding bin provided above a container and having an exhaust port from which gas is discharged, an introduction port into which grain and flour are introduced, and a supply port which supplies the grain and flour to the container; a first vacuum breaker valve opening and closing the exhaust port; a second vacuum breaker valve opening and closing the introduction port; a third vacuum breaker valve opening and closing the supply port; a temperature sensor measuring the temperature in the holding bin; a vacuum device drawing a vacuum in the holding bin; and a control device configured to control the first vacuum breaker valve, the second vacuum breaker valve, the third vacuum breaker valve, and the vacuum device, and set with a target temperature.

The present invention discloses a feeding system that comprises a plurality of material tanks having air outlets, a plurality of blowers, a dust remover having an air inlet, and a connecting pipe. Air inlets of the plurality of blowers are in communication with the air outlets of the material tanks in one-to-one correspondence. The first end of the connecting pipe is in communication with the air inlet of the dust remover, and the second end of the connecting pipe is movable between being connected with the air outlet of a first one of the plurality of blowers and being connected with the air outlet of a second one of the plurality of blowers. The disclosed feeding system a simple structure and zero dust leakage. Also disclosed is a glass production apparatus that comprises the disclosed feeding system.

A fluid mixing device includes inlet ports in fluid communication with respective source containers, an inlet check valve, a mixing container in fluid communication with the inlet check valve, a discharge port in fluid communication with a target container, and a discharge check valve in fluid communication with the mixing container and the discharge port. Responsive to a negative pressure at the mixing container, fluid is drawn from the respective source containers through the inlet ports and through the inlet check valve and into the mixing container, while the discharge check valve precludes drawing of fluid from the target container. Responsive to a positive pressure at the mixing container, fluid is expelled from the mixing container through the discharge check valve and into the target container, while the inlet check valve precludes discharge of fluid from the mixing container to the inlet ports and the source containers.

The present invention discloses a method for confined impinging jets (CIJ) mixing with imbalanced momenta. The method includes the following steps: connecting each inlet of a CIJ mixer with a to-be-mixed fluid by using an inlet conduit; connecting an outlet of the mixer with an inlet of a suction device by using an outlet conduit; and starting the suction device, enabling the to-be-mixed fluids to enter the mixer sequentially through the conduits and the inlets of the mixer and to mix in a mixer chamber, and the mixture is then sucked out from the outlet of the mixer and flows sequentially through the conduit, the inlet of the suction device, and the outlet of the suction device.
