An apparatus for containing and mixing a load of liquids and solids is disclosed. The apparatus includes an elongated tank, which includes a lower portion and an upper portion. The apparatus further includes an elongated rotatable shaft within the tank. At least one blade is connected to the shaft and is configured to mix the liquids and solids when the shaft is rotated. The apparatus also includes a shaft support configured for maintaining the shaft in a rotatable manner within the tank. The shaft support is selectively moveable in a manner permitting the shaft to move in an upward direction from the lower portion toward the upper portion, and in a downward direction from the upper portion toward the lower portion. An is contained with the tank for moving the shaft support in the upward direction and in the downward direction.

A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.

Provided herein are systems, apparatuses, and methods for localized, on-demand diesel exhaust fluid (DEF) production. The systems can comprise a loading station for securing a container comprising a pre-measured quantity of urea and releasing the urea from the container. The released urea and water can then be fed into a mixing tank to produce the DEF product. The water can be pre-treated, for example, in a reverse osmosis and/or deionization process before being fed to the mixing tank. The DEF product can be immediately dispensed into a diesel vehicle or stored in a nearby intermediate storage tank. The systems and processes advantageously reduce or eliminate the need for over-the-road shipments and retail packaging of DEF.

A multiple submergence depth diffused air system includes: a vessel having a non-flat bottom floor and fluid; a single blower or compressor that provides a single mass flow and a single pressure discharge of air; a plurality of air distribution lines that extend from the single blower or compressor into the fluid, in which outlets of the plurality of air distribution lines have grids with air diffuser units for distributing air; and orifice plates associated with each air distribution line. At least some of the air distribution lines extend to different depths within the fluid and at least one of the air distribution lines extend into the fluid formed in the non-flat bottom floor of the vessel. The orifice plates can also be sized and configured to produce a unique pressure head for each air distribution line at a designated mass flow of air to the respective air distribution line.

A device for mixing a first component with a second component includes a housing forming a first chamber for the first component, a second chamber for the second component, a separation element for separating the first chamber and the second chamber, and an activation element for creating a breakthrough through the separation element. The activation element is integrally formed with the housing and a predetermined breaking area is formed in the housing to create an outlet for withdrawing a mixture of the first component and the second component.

Disclosed are a paddle discarding fully-sealed cement stirring and solidification bucket and a liquid injection and stirring method. A stirring paddle, a bucket cover, and a stirring steel bucket are first assembled and conveyed to a feeding station for cover removal and cement filling; then the stirring steel bucket is conveyed to a stirring station; after a stirring power device, a waste liquid injection device, and a breathing and exhaust device are correspondingly connected to a stirring paddle drive connection end, a waste liquid injection interface, and a breathing and exhaust device interface, injection and stirring of radioactive waste liquid are carried out in a fully-sealed environment. In the present invention, the stirring paddle is discarded in the steel bucket, thereby avoiding the problems of secondary radioactive waste liquid produced by cleaning the stirring paddle and diffusion of radioactive aerosol in the stirring process.

A pharmaceutical compounding system includes a plurality of vials and a receptacle. The system is arranged to remove substances stored within the vials and combine them within the receptacle to form a medication, and each vial is continuously maintained gripped within the system during preparation of the medication.

A method for producing a suspension, wherein plant parts are comminuted in portions and mixed with water so that the water and the plant parts form the suspension, and a pomace remaining from the plant parts is separated from the suspension. A device for producing a suspension, the device including a mixing chamber and a mixing element in the mixing chamber for mixing a portion of comminuted plant parts with water so that the water and the plant parts form the suspension, and an outlet on the mixing chamber for letting the suspension out of the mixing chamber so that a pomace remaining from the plant parts is retained in the mixing chamber. In order to accelerate production, the plant parts are mashed to a pulp while the water is pressed at a positive pressure through the pulp and through a filter which retains the pomace.

An additive manufacturing system for additive manufacturing material with long fibers includes an extruder comprising a nozzle that includes a static-mixing portion, a compression portion, and a long fiber alignment portion. The static-mixing portion includes a static-mixing channel with static-mixing rods distributed inside and extending radially inward from a channel wall. The long fiber alignment portion has an alignment channel with a diameter D.sub.AC that is less than a diameter D.sub.SMC of the static-mixing channel. The compression portion includes with a reducing diameter from an input end to an output end of the compression channel. A nozzle and method for additive manufacturing are also disclosed.

In some examples, a mixing device is configured to receive a fluid flow in an inlet section and accelerate the fluid flow in a nozzle section fluidically coupled to the inlet section. The nozzle device is configured to discharge the fluid flow to an outlet section. The outlet section includes one or more suction ports configured to draw a material into the fluid flow via the suction ports. In some examples, the mixing device is configured to be secured to a container configured to hold a medical solution comprising the fluid flow and the material. In some examples, the mixing device is included in a mixing system configured to produce a medical solution.
