ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a mounting system for filtration media and more particularly to an adjustable mounting system for filtration media which is being used to remove solid or liquid particulate from fluid streams.
2. Description of the Related Art
Residential and commercial heating, ventilating and air conditioning systems (HVAC systems) deal with the filtration of a variety of particulate, including dust, lint and pollen. Similar filtration systems are utilized in industrial spray painting booths to collect paint droplets from the exhaust airstream. Dust collection systems are also utilized in industrial settings to capture the by-products of manufacturing processes which are entrained in airstreams. Obviously, the removal of such particulate in all of these settings is desirable for reasons of health, comfort and aesthetic appeal.
Generally speaking, the filtration media or fluid filter is placed in the fluid stream to remove the particulate from the fluid stream. In many installations, a layer of filtration media is placed in the fluid stream at right angles thereto. Such a mounting system obviously limits the surface area of the filtration media to the cross-sectional area of the fluid flow. In other words, if the fluid flow area has a dimension of 24″×24″, the area of the filtration media exposed to the fluid stream is 576 square inches. If the media surface area can be increased, the time period between change-outs of the filter media may be increased.
SUMMARY OF THE INVENTION
An adjustable mounting system for filtration media is disclosed comprising first and second upstanding panel members with each of the panel members having an upper end, a lower end, a forward edge, and a rearward edge. The upstanding panel members define an opening therebetween for the passage of exhaust air therebetween. First and second substantially vertically disposed supporting rails are provided oil the front edges of the first and second panel members, respectively. Each of the first and second support rails have a plurality of forwardly presented openings or slots formed therein. Preferably, a plurality of filtration media support frames having an adjustable V-shape are mounted on the support rails between the first and second panel members. A continuous layer of filtration media extends between the upper and lower ends of the first and second panel members and is supported by the filtration media support frames. The V-shape of each of the filtration media support frames may be adjusted to increase or decrease the angle of the V-shape. Each of the filtration media support frames are comprised of a pair of frame members hinged together so as to form a “V” when the frames are attached to the support rails. Depending on the slots used for attachment, the angle of the “V” may be varied. Additionally, the support frames are designed so that when closed to form the “V”, the frames clamp or grab and retain the filter media to maintain the filter media in close proximity to the support frame.
It is therefore a principal object of the invention to provide a mounting system for filtration media.
A further object of the invention is to provide an adjustable mounting system for filtration media.
Yet another object of the invention is to provide an adjustable mounting system for supporting a continuous roll of filtration media thereon with the media being supported in an accordion or pleated arrangement.
Still another object of the invention is to provide an adjustable mounting system for filtration media which includes a pair of horizontally spaced and vertically disposed support rails including multiple slots provided therein for the attachment of individual filtration media support frames at various locations along the length of the rails.
Yet another object of the invention is to provide an adjustable mounting system for filtration media including individual hinged frames hinged together so as to form a “V” when the frames are attached to the rails with the angle of the “V” being selectively varied.
Still another object of the invention is to provide an adjustable mounting system for filtration media including a pair of horizontally spaced and vertically disposed support rails which support individual hinged frames which include means for maintaining the filtration media in close proximity thereto.
Still another object of the invention is to provide an adjustable mounting system for filtration media which provides increased filtration media surface area which results in longer periods between filter changes and lower power requirements due to the lower pressure drop through the media.
Still another object of the invention is to provide an adjustable mounting system for filtration media which enables the operator to tune the life of the media depending upon the particular operator's requirements.
Yet another object of the invention is to provide an adjustable mounting system for filtration media of the type described above wherein the number of media support frames may be increased in localized areas between the panel members to account for the concentration of overspray in the vicinity of a spray gun or the like.
These and other objects will be apparent to those skilled in the art.
