Abstract
A portable apparatus for surface treatment with particulate material thrown onto the surface at high velocity is disclosed. The apparatus includes a device or features for removing from the surface the particulate material and debris generated by the treating process. The removing features include a magnetic drum for attracting ferromagnetic material, a vacuum packup for removing nonmagnetic material, and a plurality of air jets for positioning and lifting the material to increase the efficiency of the recovery process. The recovered material is separated according to content and the particulate is recycled for reuse.
Claims13
In a portable apparatus having means for projecting particulate material onto a surface portions of which may be grooved and for removal of debris and spent particulate thereon, the improvement comprising:
- a. magnetic means for removing ferromagnetic material from said surface;
- b. second means for removing by vacuum pickup any remaining debris and particulate from said surface;
- c. separating means receiving the removed material from said first and second means for effecting separation of debris from said particulate;
- d. means for returning the recovered and separated particulate to said projecting means;
- and
- e. means for producing an air blast on said surface to focus the debris and spent particulate into the vicinity of said magnetic means and second
A portable device for removal of debris from a horizontal surface including means for projecting ferromagnetic abrasive onto said surface comprising:
- magnetic means for removing ferromagnetic debris from said surface;
- vacuum means for removing nonmagnetic debris from said surface;
- means receiving the ferromagnetic and nonmagnetic debris for reclaiming said abrasive therefrom;
- means returning said reclaimed abrasive to said projecting means for reuse;
- and
- means for producing an air blast on said surface to focus the ferromagnetic and nonmagnetic debris and spent abrasive into the vicinity of said
In a portable apparatus having means for projecting particulate material onto a surface, portions of which may be grooved, and for removal of debris and spent particulate thereon, the improvement comprising:
- a. magnetic means for removing ferromagnetic material from said surface including a nonmagnetic rotating drum and magnets at selected fixed positions along the inner circumference of said drum;
- b. second means for removing by vacuum pickup any remaining debris and particulate from said surface;
- c. separating means receiving the removed material from said first and second means for effecting separation of debris from said particulate;
- and
- d. means for returning the recovered and separated particulate to said projecting means.
