A “fluid mixer” device that automates the mixing of multiple fluids into a base liquid and the delivery of the mixed liquid according to user-specified parameters with automatic flush-out, full logging and reporting capabilities. The device is comprised of a plurality of modules, each of which is designed for a different environmental setting: (a) the control module, the module with which the user interfaces, is normally located in a dry area, away from both line voltage electricity and fluids; (b) the power module, which supplies power to all modules, is located near 110V-230V single phase line voltage, and thus contains all of the high-voltage gear and interfaces; and (c) the flow module, the bank of controlled liquid mixers, is located in the wet area and uses only low-voltage direct current in its operation.

A fuel mixing apparatus for fuel cell system includes a first fluid tank, a second fluid tank, a tube assembly, a pump, and a mixing tank. The first fluid tank is for containing a first fluid. The second fluid tank is for containing a second fluid. The tube assembly connects to the first fluid tank and the second fluid tank. The pump is disposed on the tube assembly. The mixing tank is connected to the tube assembly. The pump transmits the first fluid in the first fluid tank to the mixing tank via the tube assembly, and the pump transmits the second fluid tank to the mixing tank via the tube assembly.

A sewage system component spray assembly is attached at a predetermined height above pumps in the interior of the component and has at least one nozzle for spraying liquid downwardly and generally tangential to a center of the sewage system component. Operation of the nozzle causes the liquid to disperse floating material on the sewage surface and creating a rotational flow around the center to direct such material to the pumps.

Embodiments of the present disclosure involve methods, devices, and systems for hydrating polymers using multiple mixing chambers. Adjacent mixing chambers may be coupled using an under-over baffle, and each mixing chamber may be generally rectangular with rounded corners.

Provided herein are methods and systems of the invention that include the use of an automated solution dispenser to form a solution according to at least one target characteristic. A controller may be operatively connected to the automated solution dispenser, wherein the controller is programmed to direct mixing of one or more solids and one or more liquids to produce the solution. At least a portion of the solution can be dispensed into one or more containers.

A system (10) for treating produce includes an application system (12) for applying a treatment liquid to the produce. A piston pump (20) is connected in liquid flow receiving communication with a source of treatment liquid (16), and also is connected in liquid flow expelling communication with an application line (18) leading to the application system. A control system (22) controls the operation of the piston pump to pump a selected dosage of the treatment liquid from the source of treatment liquid (16) to the application system (12).

A slurry blending tool may include a blending tank to receive and blend one or more materials into a slurry, and at least one inlet pipe connected to the blending tank and to provide the one or more materials to the blending tank. The at least one inlet pipe may vertically enter the blending tank and may not contact the blending tank. The slurry blending tool may include a blending pump partially provided within the blending tank and to blend the one or more materials into the slurry. The slurry blending tool may include an outlet pipe connected to the blending pump and to remove the slurry from the blending tank.

An agitation control system of an agricultural system. The agitation control system includes an agitator that induces movement of particulate material through the agricultural system. An agitator motor couples to the agricultural system to move the agitator. A first motor couples to the agitation control system. The first motor includes a first sensor that detects a first temperature of the first motor and emits a first signal indicative of the first temperature. A controller couples to the agitator motor and to the first motor. The controller receives the first signal indicative of the first temperature from the first sensor and determines an ambient temperature from the first temperature. The controller controls the agitator motor in response to the ambient temperature.

A preparation apparatus includes a first tank, a second tank, a preparation tank, and a computer having a hardware processor. The first tank contains a first liquid. The second tank contains a second liquid having a lower viscosity than the first liquid. The preparation tank stirs the first liquid supplied from the first tank and the second liquid supplied from the second tank to prepare a preparation liquid. The hardware processor measures a viscosity of the first liquid based on a supply time required to supply a specified amount of the first liquid at a constant pressure from the first tank to the preparation tank, and supplies an amount of the second liquid to the preparation tank based on the measured viscosity of the first liquid so as to cause the preparation liquid to have a target viscosity.

The present invention comprises an ultrasound stirring device. The ultrasound stirring device includes an inner container body configured for accommodating solution, an outer container body accommodating the inner container body, an ultrasound generator located between the inner container body and the outer container body, a mounting base located a side of the outer container body far away from the inner container body and configured for supporting the outer container body, a first circuit board including a control circuit configured for controlling the ultrasound generator generate ultrasound to stir the solution, and a battery configured for supplying the first circuit board.
