Abstract
A system and a method of manufacturing continuous glass filament fiberglass media comprises melting glass within a temperature controlled melter. Molten glass exits through a bushing plate with orifices of varying row configurations and orientations. The resulting fiberglass filaments are received on a rotating drum and sprayed with resin and aqueous solution. The resulting fiberglass mat is placed onto a let-off table then sprayed with aqueous solution before further processing.
Claims19
An apparatus for manufacture of continuous glass filament filtration media, comprising:
- a reservoir comprising binder and configured to control a temperature of the binder;
- a rotatable drum;
- a traversing glass melting furnace configured to move in a first direction parallel to an axis of rotation of the rotatable drum;
- a bushing plate coupled to the traversing glass melting furnace, the bushing plate consisting of Inconel, wherein the bushing plate comprises a plurality of orifices configured to spin filaments;
- wherein the traversing glass melting furnace comprises a combustion heat source positioned above the bushing plate;
- a binder sprayer coupled to the traversing glass melting furnace;
- and
- one or more shields coupled to the bushing plate and extending vertically below the bushing plate;
- wherein the one or more shields enclose no more than three sides below the bushing plate so that at least one side remains open.
