A single-pass flow-through dry chemical mixing trailer for use with a well has a trailer, a refillable liquid storage tank, a main liquid storage tank valve, a liquid storage tank inlet valve, an onboard power supply, a motor with a fuel supply, a transmission, a fluid circulation loop, a self-priming bidirectional flow alternating centrifuge pump, an automated mixer assembly, and a discharge tank. The refillable liquid storage tank prevents backflow to the self-priming bidirectional flow alternating centrifuge pump while flowing the homogenized slurry to the well and the dry chemicals introduced at the automated mixer are subjected to high shear forces, incorporating the dry chemicals into the liquid with increased dispersion and reduced agglomeration.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

The present invention discloses a sparkling water machine capable of achieving automatic resetting from gas inflow, comprising a main machine, a sub-machine, a gas inflow main body, a gas path main body, a button, a gas inflow pressure rod, a gas pressure chamber, a gas pressure valve body, a gas pressure valve rod, a first resetting device, a second resetting device and a gas inflow connecting rod hook, and the gas inflow pressure rod is provided with a through hole. When in use, gas is supplied to a carbon dioxide gas cylinder through the button, and the gas inflow pressure rod is fixed under the action of the second resetting device. When a gas pressure in a sparkling water bottle reaches a specified value, a driving end of the gas inflow connecting rod hook is pressed, thereby achieving automatic resetting and stopping gas inflow.

A raw material mixing apparatus, including mixing drums and a feed pipe, each of the two mixing drums is provided with a feed port and a discharge port, the feed ports of the two mixing drums are both communicated with the feed pipe, and a switching valve is arranged on the feed pipe; a first rotating disc and a second rotating disc are rotatably connected at two ends of each said mixing drum respectively, and a stirring assembly is connected between the first rotating disc and the second rotating disc in the axial direction of each said mixing drum; the stirring assembly includes a central stirring element and a plurality of non-central stirring elements radially arranged between inner side walls of each said mixing drum and outer side walls of the central stirring element.

A pothole filling method and apparatus with a separate liquid asphalt tank, aggregate hopper, and activator container, and having and using one or more of the following features: 1. Compressed air to deliver the liquid asphalt component from the liquid asphalt tank to the mixing head; 2. A swivel between extender delivery conduits, with an internal sleeve for guiding aggregate and protecting the swivel bearings; 3. A water cleaning system being switchable between a clean out line connected directly to a mixing/delivery unit or to the liquid asphalt delivery line, which cleans the delivery line as well as the mixing/delivery unit; 4. A mixer/delivery unit clean out is provided, wherein the unit is operated at increased speed a short time after the unit stops operating; 5. Compressed air bubbler or an air driven stirrer for mixing the liquid component. 6. A generally vertically oriented funnel shaped activator holder with a generally vertically oriented motorized auger extending to a delivery tube, to deliver activator to a mixing/delivery unit.

Delivery systems for in situ forming foam formulations are provided. The devices may include various actuation mechanisms and may entrain air into fluid formulation components in a variety of ways, including mixing with air and the addition of compressed gas.

Underwater gas pressurization units and liquefaction systems, as well as pressurization and liquefaction methods are provided. Gas is compressed hydraulically by a rising pressurization liquid that is separated from the gas by a water immiscible liquid layer on top of an aqueous salt solution. Tall vessels are used to reach a high compression ratio that lowers the liquefaction temperature. The pressurizing liquid is delivered gravitationally, after gasification, transport to smaller water depths and condensation. Cooling units are used to liquefy the compressed gas. A cascade of compression and cooling units may be used with sequentially higher liquefaction temperatures, which allow eventual cooling by sea water. The pressurizing liquid, dimensions of the vessels, the delivery unit, the coolants and the implementation of the cooling units are selected according to the sea location, to enable natural gas liquefaction in proximity to the gas source.
