The present invention relates to a welding jig micro-cleaning apparatus, and more particularly a welding jig micro-cleaning apparatus including a housing, a sandbox connected to the housing, an air supply unit connected to the sandbox through with a hose, a blasting gun positioned in the housing, a jig fixing portion positioned at a lower first end of the blasting gun, and a controller, wherein the jig fixing portion includes a magnetic unit configured to fix a welding jig.

A re-circulatory blasting device obtained is capable of performing stable treatment for a prolonged period of time even in cases in which an elastic abrasive employed has abrasive grains adhered to the surface of elastic cores. An elastic abrasive regeneration device provided to the blasting device regenerates elastic abrasive employed for re-circulation. The elastic abrasive regeneration device includes a mixer and a combining unit. Recovered abrasive fed in from an abrasive recovery section is mixed in the mixer with abrasive grains fed in from an abrasive grain feeder, and the abrasive grains are adhered to the surface of the cores of the recovered abrasive. In the combining unit, the abrasive grains are pressed against and combined to the surface of the cores by passing an aggregated state of the recovered abrasive mixed by the mixer along a constricted flow path having a flow path cross-sectional area that gradually narrows.

A blasting abrasive includes a particle of hot melt resin and abrasive grains to be firmly fixed to the particle, a blasting method further includes preparing a blasting abrasive including particles of hot melt resin and abrasive grains to be firmly fixed to the particles, heating gas, and injecting both the blasting abrasive and the heated gas.

A method of comminuting the size of particles of frangible blast media from each particle's respective initial size to a size smaller than a desired maximum size includes directing a flow of entrained particles toward a gap, at a first location splitting the flow into at least a first and second flow, the particles are entrained in the first flow, the first flow travels through the gap and substantially no particles are entrained in the second flow, and rejoining the second flow with the first flow at a second location downstream of and proximal to the gap.

An independent safety warning and notification system for sandblasting operations that require an operator of a blasting hose to be remotely positioned to the blasting pot operator. A dedicated activation switch assembly is secured to an existing sandblast hose with a separate dead man switch or alternately with an integrated dead man switch allowing the blast nozzle operator to communicate critical information to the pot operator. A warning notification light display and audible alarm assembly with a remotely positional warning light alarm is selectively secured near the pot operator for notification that a prescribed predetermined action has been requested by the blast nozzle operator or an emergency situation by activation of the switch assembly.

A micro-abrasion sandblast device having a tank for containing a supply of abrasive media and having a media outlet on a base thereof and a cabinet attached to the tank and providing a first inlet to which an external source of compressed air is connectable and a second inlet to which an external source of water is connectable. A media valve is located adjacent the base of the tank for receiving media from the media outlet and compressed air from the cabinet. A blast hose coupler connects to and extends from the media valve for receiving the media and compressed air from the media valve.

A method for cleaning a jet engine includes introducing a cleaning medium having solid materials into the engine by way of at least one discharging device, wherein the cleaning medium exits from the discharging device at an exit speed of 80 m/s or less.

A method and apparatus produce an enhanced blast stream which may be directed at a workpiece. The enhanced blast stream has higher energy allowing the blast stream to remove difficult to remove coatings from substrates. A heated flow is combined with an entrained particle flow and expelled through a nozzle. The heated flow results in more energy being imparted to the coating.

A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.

A wet media blasting system with a water injection system that provides more uniform distribution of the water, air and media components for achieving better application of the mixture while minimizing the amount of water required to contain and minimize or eliminate airborne particulate matter such as dust produced during the blasting operation. By more thoroughly mixing the water into the abrasive/water mix, the amount of water required is reduced. The abrasive feed is placed and shaped to optimize spray coverage and minimize abrasive flow into injection space thus mitigating water nozzle clogs. The abrasive flow is shaped as it is released from the metering valve in order to tighten the abrasive flow before it enters into the blast air stream. The shaped and tightened abrasive flow is maintained at the lower portion of the blast air stream. This positions the abrasive flow in optimum placement for spray wetting the abrasive as it flows into and through the nozzle. This also mitigates nozzle clogging by directing most of the abrasive flow away from the water spray nozzle port.
