Filed:

Mar 30, 2012

Appl. No.:

13/436354

Inventors:

Ernst H. Schubert - Snoqualmie Pass WA, US
Andrew Turpin - Kent WA, US

Assignee:

OMAX Corporation - Kent WA

International Classification:

B24C 7/00
B24C 3/00

US Classification:

451 60, 451 99, 451446

Abstract:

Systems and methods for fluidizing an abrasive particulate material for an abrasive water jet are disclosed herein. In one embodiment, the abrasive material is delivered to a metering orifice in a distributor. Pressurized pulses of air can be directed around a circumference of the distributor to at least partially fluidize the particulate material to facilitate the material passing through the metering orifice. From the metering orifice, the abrasive particulate material is entrained in a water jet for a cutting procedure or other suitable application.

US Classification:

451 60, 451446, 451 99

Abstract:

Particle-delivery devices, abrasive jet systems, and associated devices, systems, and methods are disclosed herein. In certain aspects, the particle-delivery devices can include an elongated fluidizing chamber and a metering assembly. The metering assembly can include a particle flow path extending from the fluidizing chamber. The metering assembly can also include a carrier-gas passage extending to an injection orifice proximate the fluidizing chamber. The metering assembly can be configured to inject carrier gas into the fluidizing chamber to fluidize particles within the fluidizing chamber. Fluidizing the particles at different carrier-gas pressures and/or flow rates can change the rate of particle delivery. For example, the metering assembly can include a metering opening and a regulator configured to change a steady-state pressure and/or flow rate of carrier gas entering the fluidizing chamber. Systems disclosed herein can include a controller configured to change a flow rate of particles through the metering opening.

International Classification:

B24C 7/00
B24C 1/04

Abstract:

Abrasive-delivery apparatuses for use in abrasive jet systems and associated apparatuses, systems, and methods are disclosed. An abrasive-delivery apparatus configured in accordance with a particular embodiment includes a first funnel segment and a second funnel segment downstream from the first funnel segment. The first funnel segment can have a first inlet, a first outlet, and a first interior region extending between the first inlet and the first outlet. Similarly, the second funnel segment can have a second inlet, a second outlet, and a second interior region extending between the second inlet and the second outlet. The first interior region can have a first inward taper toward the first outlet, and the second interior region can have a second inward taper toward the second outlet. The second inward taper can be steeper than the first inward taper when the abrasive-delivery apparatus is vertically oriented.
