Abstract
In a paint spraying booth having a fresh air inlet at one end and an exhaust at the other end, the inlet end is provided with a solid end wall and a filtering wall parallelly spaced therefrom. Through the ceiling of the booth and in the region between the end wall and the filtering wall, one or more air-inlet vertically-disposed pipes is coupled. The lower end of the pipe terminates within the booth and between the end wall and the filtering wall while the upper end extends several feet upward above the ambient dust and dirt in the atmosphere. At the exhaust end, a pair of doors are provided and on each side of the doors are vertically disposed compartments having vertical filtering walls and being coupled to an overhead duct to expel the air into the atmosphere.
Claims5
A spray paint booth for a vehicle to be sprayed with paint said booth sitting on a floor and comprising:
- a pair of parallelly disposed side walls, a pair of end walls and an overhead forming an enclosure;
- one of said end walls having a door opening formed thereon;
- a solid door assembly closing said door opening and providing access into said enclosure when said door assembly is open;
- a first filtering wall disposed within said enclosure and spaced from and parallel to said other end wall to form an appendage therebetween;
- said filtering wall extending to both side walls, said overhead and said floor;
- means for allowing air to enter said appendage from a region outside said enclosure and said appendage;
- second and third filtering walls disposed at right angles to each other and disposed within said enclosure adjacent said one end wall and on one side of said door opening to form, with said adjacent side wall, a first vertical compartment extending from said floor to said overhead;
- fourth and fifth filtering walls disposed at right angles to each other and disposed within said enclosure adjacent said one end wall on the other side of said door opening from said first compartment to form, with said one end wall and said adjacent side wall, a second vertical compartment extending from said floor to said overhead;
- a U-shaped member disposed over said overhead and over said first and second compartments to form a third compartment disposed horizontally;
- said overhead having a pair of openings disposed over said first and second compartments so that said first, second and third compartments communicate with each other;
- a vertical chimney extending from and communicating with said third compartment;
- and
- an exhaust fan disposed within said chimney to draw air out of said enclosure through either one of said first or second compartments and through said third compartment to exhaust said air out of said chimney so that the air, entering said enclosure through the said appendage, is filtered by said first filtering wall and the air, leaving said enclosure, is filtered by said second and third filtering walls and said fourth and fifth filtering walls.
