ABSTRACT:
A filtration device for filtering of temperature controlled process liquids, as for example, liquid hot melts. The filtration device includes an outer housing with a sleeve disposed within and spaced from the side wall of the housing to form a temperature regulating fluid chamber therebetween. An elongate member with a groove or channel formed therein extends between the sleeve and the housing side wall. A filter assembly having an outer casing may be removably disposed within a filter chamber formed by the sleeve. In this case, the filter casing would have a fitting extending from the casing and through the elongate groove to a process liquid inlet pipe connected to the housing side wall. Releasable bolts operatively engage the filter casing to permit holding of the casing in the filter chamber. Another fitting extends from the casing and through the elongate groove to a process liquid outlet pipe connected to the housing side wall. This construction permits easy removal of the filter casing for cleaning of the filter assembly without physically disconnecting process liquid lines or temperature regulating fluid lines. This construction also permits fairly complete temperature regulating fluid flow around the filter assembly.
