A device for cooling a slurry manufacturing mixer-comprises: a rotation container that comprises a mixing part, which mixes slurry and has a temperature detection part, and a slurry discharge part, which is formed under the mixing part and has a discharge hole for discharging the slurry; a body that is positioned under the rotation container and has a through-hole formed therethrough, through which the rotation container is inserted; and a sealing member interposed between the rotation container and the body, wherein the mixing part comprises an inner container and an outer container, and a cooling water passage is formed between the inner container and the outer container.

A shotcrete nozzle assembly comprising: a tubular body operatively connectable to a concrete source, the tubular body including a stream controlling section for controlling a stream of fresh concrete projected from an outlet body end, the stream controlling section including at least one helicoidal conduit defined within the body sidewall, each helicoidal conduit extending helicoidally around a central conduit between an air inlet end operatively connectable to a pressurized air source and an air outlet end located towards the outlet body end, each helicoidal conduit being twisted around the central passageway to guide pressurized air exiting through the air outlet end along an helicoidal path extending away from the outlet body end and around the stream of fresh concrete exiting the outlet body end.

In accordance with presently disclosed embodiments, systems and methods for using one or more pre-filled, portable containers, instead of pneumatic transfer, to move bulk material from a transportation unit to a blender receptacle of a blender are provided. A transportation unit may deliver one or more containers of bulk material to the well site, where the containers may be disposed in an elevated position around the blender receptacle. A gravity feed outlet may extend from one or more containers to route bulk material from the one or more containers directly into the blender receptacle. Since the transportation unit is able to unload the portable containers of bulk material without pneumatic transfer, the stackable containers may enable a cleaner and more efficient bulk material transfer at the site.

Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

Methods for handling bulk material in a manner that reduces dust, noise, and emissions are provided. The presently disclosed techniques use portable containers to transfer bulk material from a transportation unit to a blender inlet. The containers may be carried to the location on the transportation unit, where a hoisting mechanism is used to remove the container from the transportation unit and place it in a desired location. When bulk material is needed at the blender inlet, the hoisting mechanism may position the container of bulk material onto an elevated support structure. Once on the support structure, the container may be opened to release bulk material to a gravity feed outlet, which routes the bulk material from the container directly into the blender inlet. The disclosed containerized bulk material transfer system and method allows for reduced dust, noise, and emissions on location.

An automated drilling-fluid additive system and method for on-site real-time analysis and additive treatment of drilling fluid to be directly injected into a well without additional storage or handling. The drilling fluid includes returned drilling fluid intended to be re-used, which has a variety of viscosity and other qualities resulting from its various preceding use. The target drilling fluid will have a variety of viscosity and other qualities depending upon and changing with various phases of drilling operations and various conditions encountered. The drilling fluid is analyzed in real time as it flows into the automated drilling-fluid additive system, and various additives are added to and thoroughly blended with the drilling fluid as needed to achieve the desired result. The blended drilling fluid is collimated to produce a laminar flow and is discharged from the automated drilling-fluid additive system in the proper condition for direct injection into a well without any storage in a holding tank and without any further processing, treatment, or handling.

An apparatus, comprising a magnetically conductive conduit having a fluid entry port, a fluid impervious boundary wall and a fluid discharge port defining a fluid impervious flow path through the magnetically conductive conduit, at least one end of the conduit having a taper forming a planar surface extending from an outer to an inner surface; an electrical conductor comprising a length of an electrical conducting material having a first and second conductor lead, the electrical conductor coiled with at least one turn to form an uninterrupted coil of electrical conductor encircling a section of the outer surface of the magnetically conductive conduit; and an electrical power supply operably connected to at least one of the first and second conductor leads, wherein the at least one coiled electrical conductor is thereby energized to provide a magnetic field having lines of flux directed along a longitudinal axis of the magnetically conductive conduit.

A system for preparing a polymeric mixture includes: a containment device configured to distribute dry polymeric materials; a receiving chamber in fluid communication with the containment device; a wetting bowl; a dispersing channel; and a mixing chamber connected to the dispersing channel. A method of preparing a polymeric mixture includes distributing water and dry polymeric materials through the various components of the system and mixing the materials with the mechanical mixing device.

An apparatus for extracting cannabis essential oils. A housing is provided for containing trichome material from a cannabis plant, the housing having a sealable opening. A rotatable impeller is disposed in the housing. A container is connected to the housing for collecting essential oils. The process for extracting cannabis essential oils includes the steps of introducing trichome material from the cannabis plant into the housing, introducing water and ice into the housing via an opening therein, and agitating the water and ice and the trichome material to separate and extract essential oils therefrom.

A method in which a stream of dry cementitious powder passes through a first conduit and aqueous medium stream passes through a second conduit to feed a slurry mixer to make cementitious slurry. The cementitious slurry passes through a third conduit and a reinforcement fiber stream passes through a fourth conduit to feed a fiber-slurry mixer which mixes the slurry and discrete fibers to make a stream of fiber-slurry mixture. An apparatus for performing the method is also disclosed.
