A paint spray booth water washed subfloor system, including distribution piping for supplying water to only one portion thereof. The distribution piping has only one main pipe to supply water to the one portion of the subfloor. The water supplied to the one portion of the subfloor is then transferred from that portion through a trough extending across and forming part of the subfloor to provide water to the other portions of the subfloor. Preferably, at least a part of the subfloor's other portions are sloped downwardly from both sides toward a center slot or opening for generating a fall of water to mix with paint overspray laden air descending through the center opening. The distribution piping is provided with special valves for throttling the flow of water onto the subfloor, but yet permitting maximum flow, and assisting the flow of water into the trough portion, and hence, to the other portions of the subfloor. Following the principles of the invention, a spray booth subfloor of any desired length can be constructed, simply by adding a number of similar sections or modules together to achieve the desired length.
A water washed subfloor system for a paint spray booth or the like, comprising a subfloor having two sides with a downwardly sloped panel on each of said sides, discharge orifice means in said subfloor at the lower edges of and between said two sloped panels, a single main water distribution pipe adjacent the subfloor for delivering water to said subfloor, means in said subfloor for distributing water from said main pipe to both of said sides of said subfloor, and means for flowing water uniformly from each of said sides onto said sloped panels and into said orifice means, whereby water admitted from said single main water distribution pipe flows therefrom to said means in said subfloor for distributing the water to both of said sides of said subfloor, uniformly across said sloped panels of said subfloor, and into said orifice means, and said orifice means receives water from both sides of the subfloor, though water is admitted only from said single main distribution pipe.
A subfloor system for a paint spray booth or the like, comprising a subfloor, a main water distribution pipe, at least one riser extending from said main water distribution pipe to and communicating with said subfloor, and a volume control valve in each riser, said volume control valve comprising a pair of relatively movable cone-shaped elements for regulating the flow of water through said valve, each of said cone-shaped elements having openings therein alignable with each other for forming an open position and alternatively misalignable with each other for forming at least one partially open position, said openings in said cone-shaped elements being approximately the area of the internal cross section of said riser, and an adjustment mechanism for said control valve extending from said cone-shaped elements through said riser to above said subfloor, said adjustment mechanism altering the relative position of said cone-shaped elements to one another and being adjustable from above said subfloor, whereby said volume control valve when in the open position does not unduly restrict water flow through said riser and can be readily adjusted to balance the flow onto said subfloor from said subfloor.
A water-washed subfloor system for a paint spray booth or the like, comprising a subfloor having a substantially flat portion including spaced side areas and at least one cross trough extending between and interconnecting said side areas, a weir extending upwardly from said flat portion at the inner edge of each of said side areas, a downwardly sloped panel extending inwardly and downwardly from each of said weirs, said panels forming a discharge orifice at their inner lower ends, a closure member extending upwardly from said flat portion along the edges of said cross trough between said weirs, said weirs extending upwardly to essentially the same level and said closure members extending upwardly to a higher level than said weirs, a water supply main extending adjacent said subfloor and communicating with said flat portion thereof for delivering water thereto, said weirs and said closure members causing the water to accumulate uniformly over said flat portion of said subfloor to the level of said weirs and causing the water to be delivered to and uniformly distributed over said weirs and onto said sloped panels for uniformly distributed descent over said sloped panels and into said discharge orifice.
