Definitions

  • the present invention relates generally to particle blast systems apparatus, and is particularly directed to a device with a synchronized feeder and particle generator.
  • the invention will be disclosed in connection with, but not limited to, a carbon dioxide blasting system having a shaver which is synchronized by a drive belt to the feeder.
  • Particle blasting systems have been around for several decades.
  • particles also known as blast media
  • Particles are fed by a feeder into a transport gas flow and are transported as entrained particles to a blast nozzle, from which the particles exit, being directed toward a workpiece or other target.
  • Particles may be stored in a hopper or generated by the blasting system and directed to the feeder for introduction into the transport gas.
  • One apparatus for generating carbon dioxide particles is known as a shaver, such as disclosed in USP 5,520,572 which is incorporated herein by reference, in which a working edge, such as a knife edge, is urged against and moved across a block of carbon dioxide.
  • Particles also referred to as granules
  • Particles are thus generated and fed to the inlet of a feeder.
  • a feeder is disclosed in United States Patent Application Serial Number 10/123,974, filed on April 17, 2002 for Feeder Assembly For Particle Blast System, which is incorporated herein by reference.
  • FIG. 1 is a perspective view of a particle blast system constructed in accordance with the teachings of the present invention, with the outer panels removed to reveal the components.
  • FIG. 2 is a an end view of a portion of the particle blast system of FIG. 1.
  • FIG. 3 is a side view of the drive motor, the feeder, the end of the shaver, and the drive belt.
  • FIG. 4 is a side cross-sectional view similar to FIG. 3, taken along line A-A of
  • FIG. 5 is an enlarged view of the rotor of the feeder
  • particle blast system generally indicated at 2, include frame 4 which provides support for the components, and to which outer panels (not shown) are attached, enclosing most of the components.
  • System 2 includes particle generator 6, feeder 8 and control panel 10.
  • Generator 6 is depicted as a shaver configured to received a standard size commercially available block of dry ice, such as a 6" x 6" x 12" block.
  • one end of generator 6 includes housing 12 within which the particles, or granules, are formed and allowed to flow by gravity to inlet 14 of feeder 8.
  • housing 12 houses rotatable carrier 15 which carries one or more working edges 16, which is urged against and moved relative to the dry ice block (not shown) to shave granules off of the block. Particles flow from the block downwardly into inlet 14 and into cavities 18, also referred to as pockets, formed in the circumferential surface of rotor 20.
  • Rotor 20 may be driven directly by motor 22 as shown, such as through legs 24, or may be driven indirectly through any suitable power transmission configuration.
  • the particles are transported to discharge 26 of feeder 8, where they are introduced into the transport gas flow, exiting out exit port 28 to which the delivery hose (not shown) is directly or indirectly connected, for transport to the blast nozzle (not shown).
  • Inlet port 30 of feeder 8 is connected to a source of transport gas (not shown) having suitable flow capacity and pressure, such as up to 125 psi.
  • Carrier 15 is supported and driven by shaft 32 which is rotatably supported by housing 12.
  • Drive pulley 34 is fixed to shaft 32, with key 36 preventing rotation therebetween. Any suitable construction may be used to connect drive pulley 34 non-rotatably to shaft 32, such as splines.
  • Drive pulley 34 is connected to end 38 of rotor 20 by drive belt 40.
  • Drive pulley 34 includes a plurality of teeth 42 which engage complementarily shaped teeth formed on the inside of drive belt 40.
  • End 38 also includes a plurality of complementarily shaped teeth 44 which engage the inside of drive belt 40.
  • An idler 46 may also be used.
  • This synchronizes the generation of particles by particle generator 6 relative to the feed rate of the particles through feeder 8.
  • the particles are transported immediately into the transport gas, thereby preferably moving continuously, avoiding being in a static state and avoiding agglomerating.
  • the ratio is approximately 10:1, with the feed rate of particles being about one pound per minute introduced to a transport gas of 25 to 50 standard cubic feet per minute. Different ratios may be used, depending on the desired feed rate, such as might be necessary when higher flow rate nozzles are utilized.
  • Any suitable drive mechanism may be used, such as a chain and sprocket.
  • a variable transmission may be provided, allowing easy use of different flow rate nozzles and transport gas flows.
  • Motor 22 may be interposed between shaft 32 and rotor 20, with the appropriate drive mechanisms between shaft 32 and motor 22 and rotor 20 and motor 22. Any suitable source of rotary motion and power may be used.
