A mixing tank is disclosed for reducing ingestion across an interface. The tank may include a first zone including most of the volume of the tank; a second zone including the interface; a source of mixing energy configured to provide a first bulk energy dissipation rate in the first zone; a divider located between said first zone and said second zone inhibiting transfer of said mixing energy from said first zone to said second zone to preserve in said second zone a bulk power dissipation level less than a said first bulk power dissipation level; and a mass transport passageway between said first zone and said second zone for preserving a uniformity between the first and second zones. A method is disclosed for manufacturing a mixing tank and for retrofitting and existing mixing tank and for managing mixing to prevent air ingestion.

The invention discloses a method for predicting the solubility of at least one species at a specified pH value in an aqueous buffer comprising at least one weak acid species and/or at least one weak base species. The method comprises the steps of: a) selecting a start composition of the buffer, giving a start value for the total solute concentration; b) calculating the concentrations of all ionic species present in the buffer at the specified pH value from the total composition of the buffer and available dissociation constants; c) calculating the solubility limits of each combination of ionic species present in the buffer from available solubility products, taking the concentrations calculated in step a) into account; d) comparing the concentrations of all ionic species calculated in step a) with the solubility limits calculated in step b) and determining if any solubility limit is exceeded; e) if no solubility limit is exceeded, increasing the total solute concentration of the buffer or, if at least one solubility limit is exceeded, decreasing the total solute concentration of the buffer, and; f) repeating steps b)-e) until a predetermined convergence criteria is met.

A mixing apparatus for mixing particles in a liquid and its use are disclosed. The mixing apparatus comprises a tank having a bottom and a substantially vertical side wall, an agitation means comprising a rotation shaft located vertically and centrally in the tank, and an impeller arranged at a height above the bottom at the end of the rotation shaft and the impeller being a downward pumping axial or mixed flow impeller. The bottom is equipped with a corrugated formation comprising alternate consecutive ridges and valleys, the ridges and valleys extending radially in relation to a center of the bottom, whereby the valleys concentrate and channel the mixing power near to the bottom to direct the flow of the liquid and to increase the velocity of the flow near to the bottom.

A rotary machine for mixing, pumping or agitating a fluid includes an impeller for acting on the fluid, a drive unit for rotating the impeller around a rotation axis, a drive shaft connecting the impeller with the drive unit, a mounting flange for fastening the rotary machine to a wall of a vessel, and a support structure for supporting the rotary machine, the support structure comprising at least one leg, each leg extending in a vertical plane from a first end along a longitudinal axis to a second end, each leg including an outer member and an inner member coaxially arranged in the outer member, and the inner member slidingly movable relative to the outer member for adjusting the length of the respective leg. In addition, a method of mounting a rotary machine for mixing, pumping or agitating a fluid to a wall of a vessel is proposed.

An apparatus and method for manufacturing an electricity storage material are provided which allow easily measuring the dissolution rate to solubility of a solution of a powder thickener dissolved in a liquid solvent. An apparatus for manufacturing an electricity storage material includes: a dissolving device that dissolves in a liquid solvent a thickener as powder that is ionized when dissolved; and a dissolution-rate-to-solubility determining device that measures conductivity of the solution produced by the dissolving device and determines a dissolution rate to solubility of the solution based on the measured conductivity. The dissolution rate to solubility can thus be determined without the need to stop the dissolving device during dissolution of the thickener in the liquid solvent. This can significantly improve production efficiency. Since excessive operation of the dissolving device can be prevented, energy saving can be achieved.

In accordance with embodiments of the present disclosure, systems and methods for passively reducing or preventing dust formation in a particulate handling system are provided. In some embodiments, the handling system includes a silo for holding bulk material used to form a well fracturing treatment fluid. The silo may include a chute to deposit a portion of the bulk material from the silo into a blender and a cyclone mounted to the silo to separate dust from a pneumatic air flow and to release a substantially clean air into the atmosphere. In other embodiments, the handling system may include a horizontally oriented cyclone assembly mounted to a blender storage tank, cyclone assembly including a horizontally oriented cyclone separator to separate dust from a pneumatic airflow and a dust collection container to receive the dust and output the dust into the storage tank.

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 mixing assembly includes a main flow conduit having an inlet end and an opposite outlet, a source of pressurized air at the inlet end, a container of stucco in fluid communication with the flow conduit, and a source of water in fluid communication with the flow conduit between the outlet and the container. The pressurized air draws stucco from the container into the flow conduit, and also draws water into the flow conduit to form an atomized slurry.

A mixing assembly includes a bag of appropriate size, configuration, shape and material and a closable spout that may have extensions of various lengths, shapes and configurations to provide enhanced mixing of a component contained in the bag upon the addition of a second component. Once the closure of the spout is removed, the second component, typically a liquid such as water, milk, juice, chemical, oil substrate, or the like, can be added to the container for mixing. After the closure is refitted, the two components are mixed then consumed or dispensed, either by removing the closure or from a separate spout or nozzle fitted to the closure.
