Abstract
A recovery system (10) is disclosed for recovering a treating material (12) for treating a surface (20) with a vacuum source (25). The treating material (12) may be a cleaning material such as sand, water or may be a coating material such as a paint or a plasma coating. The apparatus (10) ,comprises a housing (16) having a housing opening (18) for projecting the treating material (12) from a nozzle (14) through the housing opening (18) onto the surface (20). A fluid seal means (30) provides a seal between the housing (16) and the surface (20). The vacuum source (25) is connected to the housing (16) for withdrawing the treating non-adhering material (12A) from the housing (16).
Claims21
A recovery system for recovering a treating material with a vacuum source, the treating material being supplied by a pressurized source of treating material for treating a surface, comprising in combination:
- a housing having a housing opening;
- nozzle means connected to the pressurized source of the treating material secured to a nozzle support;
- housing mounting means for mounting said nozzle support to said housing enabling said nozzle means to project the treating material through said housing opening to impact onto the surface;
- fluid seal means defining a fluid sealing element;
- fluid seal mounting means for mounting said fluid sealing element about said housing opening;
- said fluid seal means comprising a fluid under pressure flowing between said fluid sealing element and the surface into said housing opening to establish a fluid cushion between said fluid sealing element and the surface for providing a seal between said housing opening and the surface;
- and
- vacuum connection means for connecting the vacuum source to said housing for withdrawing non-adhering material from the housing.
A recovery system for recovering a coating material with a vacuum source, the coating material being supplied by a pressurized source of coating material for coating a surface, comprising in combination:
- a housing having a housing opening;
- nozzle means connected to the pressurized source of coating material secured to a nozzle support;
- housing mounting means for mounting said nozzle support to said housing enabling said nozzle means to project the coating material through said housing opening to impact onto the surface;
- fluid seal means defining a fluid sealing element;
- fluid seal mounting means for mounting said fluid sealing element about said housing opening;
- said fluid seal means being connected to a fluid pressure source for discharging a fluid under pressure through said fluid sealing element to provide a seal between said housing opening and the surface;
- and
- vacuum connection means for connecting the vacuum source to said housing for withdrawing non-adhering coating material from the housing.
A recovery system for recovering a selected gas with a vacuum source during the application of a coating material onto a surface, the coating material being supplied by a pressurized source of coating material, comprising in combination:
- a housing having a housing opening;
- nozzle means connected to the pressurized source of coating material secured to a nozzle support;
- housing mounting means for mounting nozzle support to said housing enabling said nozzle means to project the coating material through said housing opening to impact onto the surface;
- fluid seal means defining a fluid sealing element;
- fluid seal mounting means for mounting said fluid sealing element about said housing opening;
- said fluid seal means being connected to a pressure source of the selected gas for discharging the selected gas under pressure through said fluid sealing element to provide a seal between said housing opening and the surface;
- said gas flow from said plurality of fluid seal ports into said housing opening establishing a selected gas atmosphere within said housing;
- and
- vacuum connection means for connecting the vacuum source to said housing for withdrawing said selected gas from the housing to recover said selected gas thereby.
