A brine machine comprises a salt hopper, a source of water for wetting salt in the salt hopper, a brine hopper positioned in side-by-side relation relative to the salt hopper, a filter providing fluid communication between the salt hopper and the brine hopper, a generally horizontal auger positioned in a base of the salt hopper, and an upwardly directed lift auger having a first end in operable association with an end of the horizontal auger and a second discharge end positioned above a level of brine in the brine hopper. The augers convey solid material from the base of the salt hopper and discharge the material from the machine.

Described herein is a baby bottle formula mixing and feeding assembly designed to be coupled to a standard baby feeding bottle or powder mixing bottle. The formula mixing assembly is designed to include at least four main components: a bottom housing, a cylindrical gate body, a top housing and a cylindrical pliable cup body disposed within the top/bottom housing. A locking mechanism is included that unlocks the top housing and the gate body containing the pliable cup body and the formula, such that the apertures in the gate body align with the apertures in the bottom housing to when the top housing is rotated so as to empty the formula contents into the bottle with the liquid. e both the bottom housing and the gate body.

A method of providing a salt solution at a wellbore site includes delivering solid salt in a mixing tank containing water from a local source and pumping the water through nozzles in the mixing tank using a pump adjacent to the mixing tank to circulate the water in the mixing tank and form a concentrated brine by dissolving the solid salt in the water. The concentrated brine is transferred from the mixing tank to a reservoir using the pump, and the concentrated brine is diluted with additional water from the local source to form a dilute brine. A related mixing tank and a system including the mixing tank and a vehicle structured and configured for travel over a roadway and within an oilfield site.

A dissolution generator apparatus includes: a dissolution generator, including: a housing shell; a powder support screen assembly extending across an interior of the housing shell and configured to support a column of powder; a pressure mechanism disposed adjacent the powder support screen assembly; a spray delivery assembly located adjacent the powder support screen assembly opposite to the pressure mechanism, the spray delivery assembly comprising a spray nozzle configured to spray a solvent through the powder support screen assembly; a duct having a first end in fluid communication with the housing shell, and a second end; a dissolved powder reservoir in fluid communication with the second end of the duct; and at least one recirculation pump disposed in fluid communication with both the dissolved powder reservoir and the spray delivery assembly, so as to form a fluid recirculation loop between the dissolved powder reservoir and the spray delivery assembly.

A system for dissolving solid chemical may include three reservoirs positioned in a vertically stacked arrangement. A solid chemical reservoir configured to receive solid chemical to be dissolved may be nested in a solution generator reservoir into which water is introduced to erode the solid chemical. A dissolved chemical reservoir can be positioned under the solid chemical reservoir and the solution generator reservoir. The dissolved chemical reservoir can store solution generated using the system. In some examples, a recirculation circuit is used to recirculate water introduced into the solution generator reservoir until a solution having a target concentration of the chemical being dissolved is achieved. The recirculation circuit may include a recirculation line having an outlet aimed at the bottom wall of the solid chemical reservoir.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.

A system for continuously making-down a dry powder material is provided. The system may include a liquid supply system, a material feed system, a vessel, a filter, and an agitator. The vessel may receive a continuous supply of liquid from the liquid supply system and a continuous supply of dry powder from the material feed system. The liquid and material may be discharged continuously from the vessel. A filter may sealingly extend across the outlet to filter the solution exiting the vessel. The filter may include an upstream surface in contact with the inner volume of the vessel. The agitator may be disposed within the vessel and may be configured to agitate the contents of the vessel. The agitator may include a wiping member configured to contact the upstream surface of the filter while agitating the contents.

A sieve-like filter unit, especially for a cartridge-shaped receptacle, which is arranged on a connecting port/connector of the receptacle and is designed to withhold undissolved powder and/or solid particles present in the receptacle, comprising at least two openings each being composed of at least two connected part recesses, wherein each individual opening in its entirety is formed to be extending in a non-linear manner.

The present invention relates to a device for preparing a dialysis concentrate or another fluid, wherein the device includes an inflow for the raw material for the dissolving of or mixing with a raw material located in a container that can be dissolved in the solvent or can be mixed with it and a container having a raw material to be dissolved by means of the solvent or miscible with the solvent, wherein the device has connection means for connecting to the container, characterized in that the device has a mixing unit that is self-regulating and a mixing line and a suction unit arranged in the mixing line and a mixing chamber, with the suction unit being able to be brought into fluid communication with the inflow for the solvent and, by means of a suction line, with the container connectable to the device, and with a return line downstream of the mixing chamber leading back to the container connectable to the device.
