Abstract
An apparatus for guiding bulk material transported by a pneumatic conveying line or by gravity into a container having an access spout generally consisting of means for supporting the container; a housing mountable on the supporting means including a cylindrical side wall having a lower open end insertable into the spout of the container, a closed upper wall having an opening disposed axially relative to the side wall through which a discharge end portion of the pneumatic conveying line may be inserted, a partition formed of a filter medium disposable between the side wall of the housing and the discharge end portion when such portion is inserted through the upper wall opening of the housing, providing a closed chamber and an open chamber communicating with the lower open end of the housing, and an outlet communicating with the closed chamber; and means mounted on a lower end of the housing side wall selectively operable to engage the spout when the lower end of the cylindrical side wall is inserted into the spout for forming a seal between the lower housing end and the spout.
