Abstract:
A mixing device may define a mixing chamber including a vortex mixing portion, a primary gas path along which a first gas stream moves to the vortex mixing portion, and a secondary gas path along which a second gas stream moves to the vortex mixing portion. The mixing device may have a mixer body, an outer gas guide positioned in the mixer body to guide the second gas stream to the vortex mixing portion, and an inner gas guide at least partially positioned in the mixer body to guide the first gas stream to the vortex mixing portion. A portion of the inner gas guide may be positioned in the outer gas guide to form an annular gap between the gas guides to define the secondary gas path about the primary gas path to create a vortex of the first and second gas streams in the vortex mixing portion.
Abstract:
Wet abrasive blasting systems are described that have a slurry piping system and a gas piping system that have pipes and other piping components, such as valves and regulators, that have a more consistent internal cross-sectional area than conventional wet abrasive blasting systems. The more consistent flow area provides astonishing improvements in blasting efficiency and consistent and predictable slurry flow rates.
Abstract:
An extendable bag roller for supporting a bag of material during removal of the material from the bag includes a bag support having a curved surface configured to support the bag of material on the curved surface and a roller that rolls along the curved surface of the bag support to squeeze the material out of the bag. The bag support includes a base defining a first portion of the curved surface of the bag support and an extension defining a second portion of the curved surface of the bag support, the extension being moveable to selectively increase and decrease the area of the curved surface of the bag support to accommodate different bag sizes.
Abstract:
A dispensing device for connection to a drone is provided. The dispensing device has an outer housing and an inner housing interior of the outer housing. The inner housing has an inner cavity having an entrance opening and an opposing exhaust opening. The area between the outer housing and the inner housing defines an outer cavity adapted to hold a material. The dispensing device also has a fluid access opening to provide fluid access between outer cavity and the inner cavity to allow material in the outer cavity to be transferred to the inner cavity and mixed with air to create an air and material mixture. An air accelerator is provided adjacent the inner cavity to accelerate the air and material mixture out of the dispensing device.
Abstract:
Embodiments of the present disclosure describe a mixing nozzle, system implementing the mixing nozzle, and corresponding method of use. The mixing nozzle includes a housing defining a mixing chamber that has a sidewall separating a first end from a second end. A set of tangential feed conduits, which are oriented tangentially to the mixing chamber, extend outwardly from the mixing chamber, through the housing. An outlet orifice is located in the second end, which is one end of an exit channel extending through the housing.
