A polymer flocculant mixing and dissolving system comprising: a mixing tank (2) in which a solid polymer flocculant is mixed with water used as a solvent; a liquid feed unit (3) for feeding an aqueous solution containing the polymer flocculant from the mixing tank; a regenerative mixer (4A,4B) used to mix and dissolve the polymer flocculant by applying pressure to the aqueous solution containing the polymer flocculant fed from the liquid feed unit while forming a vortex flow; a process channel (61) through which the aqueous solution that has passed through the regenerative mixer is fed to a downstream process; a circulation channel (62) through which the aqueous solution is returned to a position on an upstream side of the liquid feed unit; and a flow rate adjusting unit (6) for adjusting a balance between a flow rate of the aqueous solution flowing through the process channel and a flow rate of the aqueous solution flowing through the circulation channel. The polymer flocculant mixing and dissolving system can stably supply the solution in an amount required in the downstream process.

A slurry production apparatus includes: a mixing device (including a dispersion mixing section) that mixes a liquid and a powder to produce a slurry; a powder supply device that supplies the powder to the mixing device; a powder dry box that accommodates an opening portion of the powder supply device; and a first dry booth that accommodates the mixing device and the powder dry box.

Provided are a system for manufacturing dispersion liquid of carbon nanotubes and a method of manufacturing a dispersion liquid of carbon nanotubes using the same. The system includes; a mixing device supplied with solvent and carbon nanotubes, and storing a admixture of the solvent and the carbon nanotubes; a first dispersion device connected to the mixing device, performing a primary dispersion of the carbon nanotubes by an operation of a rotor and a stator, and then performing a secondary dispersion to form bent portions in the carbon nanotubes while discharging the carbon nanotubes through penetration holes of the stator; and a second dispersion device performing a tertiary dispersion of the carbon nanotubes to selectively cut the bent portions of the carbon nanotubes by irradiating a laser when the secondarily dispersed admixture recirculates to the mixing device.

A particle-carrying feedstock is mixed by a rotor-stator mixing mechanism placed within a mixing chamber where mixing is conducted under a negative pressure for separating and removing entrained air from the mixed feedstock, preferably before passing the de-aerated mixed feedstock to a media mill for processing into a particle dispersion. The rotor of the rotor-stator mixing mechanism preferably includes a disk carrying vanes on opposite faces of the disk for a conducting simultaneous dual mixing operations. Openings in the stator are provided with an H-shaped cross-sectional configuration and are intermingled for facilitating the mixing operation while maintaining the integrity of the rotor-stator mixing mechanism.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (e.g., mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The preparation sub-system may comprise a slurry recirculation flow loop configured with devices to stir, measure, and adjust a water to solids ratio of the slurry.

Provided is a method for manufacturing an active material mixture, the method including: supplying and dispersing a solid electrolyte in a dispersion medium while circulating the dispersion medium (a first dispersion step); and thereafter supplying and dispersing an active material and a conductive material in the dispersion medium (a second dispersion step), wherein an average rotation speed of the rotor in the second dispersion step is lower than an average rotation speed of the rotor in the first dispersion step. Aggregation of the solid electrolyte can be suppressed by separately performing the first dispersion step and the second dispersion step, and the increase in temperature of the active material mixture can be reduced by lowering the rotation speed of the rotor in the second dispersion step.

The present invention relates to a punch down apparatus and rotating sprayer that is axially movable along its shaft through the supporting vat, also provided with an element for breaking the solid upper cover referred to as “cap” in the art.

A fine-bubble mixed liquid producing apparatus 1 includes a reservoir 4 and a bubble feeding means 6 for feeding bubbles to a liquid L stored in the reservoir 4, wherein the bubble feeding means 6 includes a rotary cylinder 20 having an emitting part 22 on the outer circumferential surface, the emitting part 22 for being rotationally driven by a drive means 10, a circulating means 40 for drawing out the liquid L stored in the reservoir 4 and feeding the liquid L from the emitting part 22 to the reservoir 4, and a gas-liquid mixing part 50 for mixing bubbles with the liquid L circulated by the circulating means 40. This apparatus enables a fine-bubble mixed liquid to be efficiently produced.

Provided is a slurry manufacturing apparatus including: a mixing unit that mixes a predetermined powder and a solvent in a mixing chamber to produce a slurry; a supply unit that supplies a reaction gas to the mixing chamber when the slurry is produced by the mixing unit; and a circulation unit that recovers a surplus of the reaction gas from the mixing chamber and resupplies the surplus of the reaction gas to the mixing chamber.

A system for growing algae includes a pivot arm pivotally coupled to a pivot connection positioned in a pond containing water and algae, and a mixing device coupled to the pivot arm and extending into the pond to mix the water and the algae as the pivot arm rotates.
