An automatic mixing machine includes a vessel, a shell, a motor, a mixing unit, a detection and feedback unit, a computing control unit and a drive unit. The shell is connected with the vessel to form a closed space. The motor is arranged in the shell. The first end of the mixing unit is connected with the motor, and the second end of the mixing unit extends into the closed space. The detection and feedback unit is electrically connected with the motor and collects at least one electric parameter of the motor. The computing control unit is electrically connected with the detection and feedback unit and generates a control signal according to the electric parameters and the mixing parameters. The drive unit is electrically connected with the computing control unit and the motor respectively, and outputs a drive signal to drive the motor according to the control signal.

A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.

A mixing system is configured to mix and discharge a paste. The mixing system includes a base-medium subsystem that provides a base fluid-medium. The mixing system further includes an additive-medium subsystem that provides one or more additive fluid-mediums. The mixing system further includes a density-reducing medium subsystem that provides a density-reducing medium.

A mixer support assembly for use in an integrated cover and mixer apparatus and anaerobic digester system incorporating same provided. The digester system includes a tank with an integrated cover and mixer apparatus which provides a completely or substantially gas tight enclosure for the collection of biogas. The integrated cover and mixer apparatus includes a cover, a mixer, and a mixer support assembly for supporting the mixer. The mixer support assembly includes a float ring and a support body that is selectively removable from the float ring. The support body is attached to the float ring by way of a clamping arrangement.

This invention (FIG. 1) was conceived out of necessity to control hazardous conditions created while mixing materials like concrete or mortar in containers (1) such as a three gallon or five gallon bucket. The invention (2) is a vacuum attachment which produces a low pressure zone within the bucket when a vacuum is applied to the outlet port (3) of the invention that will keep dust and other airborne material from leaving the interior of the invention through the top of the opening (4). It consists of a funnel shaped opening (4) on the top and a channel around the underside of the funnel leading to the vacuum attachment opening (3), which creates high and low pressure zones, which controls the release of particulate into the atmosphere.

This invention is a mobile water and chemical delivery system that allows for the injection of a chemical in the path of the water line under high pressure. The system allows for mobile agricultural workers to move large quantities of clean water between job sites to use to deliver agricultural chemicals inline without having to carry large quantities of chemicals into the field. The chemicals are injected between the mobile water tank and the hoses that take the water from the tank to the application site. The purity of the mobile water source remains constant even if there is a change in the chemical.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

A beverage mixing assembly includes a gasket that is positioned around an open end of a beverage container. The gasket is comprised of a resiliently stretchable material for accommodating a variety of sizes of beverage containers. A housing is coupled to the gasket for gripping the housing and a motor is positioned within the housing. A shaft releasably engages the motor such that the motor rotates the shaft when the motor is turned on. The shaft extending downwardly into the beverage cup when the gasket is positioned around the open end of the beverage container. A mixer is coupled to the shaft such that the shaft rotates the mixer when the motor is turned on thereby facilitating the mixer to mix the beverage in the beverage container.

A blender includes a lid configured to shield the opened upper surface of a container, in which the lid includes a main lid seated on the container and having a through-hole opened to communicate with an inside of the container, a gasket provided around the main lid and being in contact with the inner surface of the container, and an auxiliary lid inserted into the through-hole and exposed from the upper surface of the main lid, the auxiliary lid is coupled to the main lid and rotated together with the main lid in a state of being inserted into the through-hole, and the gasket protrudes to be in close contact with the inner surface of the container according to the rotational manipulation of the auxiliary lid.

According to some aspects, a mixer for detection and/or removal of material in an undesired location of an additive fabrication device is provided. For instance, in an inverse stereolithography device, liquid photopolymer may adhere and cure or partially cure to a surface of the additive fabrication device in a location that may interfere with the additive fabrication process and/or cause the additive fabrication process to be unsuccessful. The mixer may be coupled to a movable structure within the additive fabrication device so that the mixer, when coupled to the movable structure, may be moved along at least one axis within the additive fabrication device. The mixer may be configured to detect and/or remove undesired material from a surface within the additive fabrication device.
