Abstract
A filter element constructed of stainless steel. The element includes a pair of filter media concentrically disposed to receive parallel flow of the filtrant. The element is adapted for disassembly to remove the filter media. The various component parts of the filter element may thereafter be easily cleaned and the filter media replaced. The filter media after being removed may also be cleaned and reused if desired. The component parts include appropriate guard assemblies to protect the filter media during handling and use.
Claims9
A dual metallic filter element for filtering materials having a viscosity in excess of about 200 poise at temperatures in excess of about 100.degree. C. and pressures in excess of approximately 400 p.s.i. and having dual replaceable spaced apart filter media, said material being filtered by flowing through each of said media from one side thereof, the upstream side, to another side thereof, the downstream side, comprising:
- (A) outer stainless steel metal filter media perforate support tube means;
- (B) outer stainless steel metal filter media perforate tubular guard shield means;
- (C) first tubular stainless steel metal filter media disposed between said outer tube and shield means;
- (D) inner stainless steel metal filter media perforate support tube means;
- (E) inner stainless steel metal filter media perforate tubular guard shield means;
- (F) second tubular stainless steel metal filter media disposed between said inner tube and shield means;
- (G) said first filter media being concentrically disposed outwardly relative said second filter media and defining an inner tubular volume surrounded by an annular outer void volume, said volumes having adjacent first ends and adjacent seconds end;
- and
- (H) retaining means including cap means and fitting means removably securing each said filter media on its respective support tube means and plugging said first end of said tubular volume and said second end of said annular void volume respectively, said support tube means being disposed opposed each other, defining said annular outer void volume, and being on the downstream side of the flow of said material through each said filter media.
