Abstract
A motionless mixer including a number of baffles attached to a central rod is slidably mountable within a hollow cylindrical conduit. A cross member is attached across the interior of the conduit and is configured to mate with a slot formed in the downstream end of the central rod, to prevent longitudinal motion or rotation of the mixer within the conduit.
Claims2
A motionless mixer includes
- a substantially cylindrical conduit defining a channel having a central axis;
- an elongated member disposed longitudinally within said channel along said central axis, said elongated member having a transverse end surface and a slot-like aperture extending into and across said end surface;
- a plurality of baffle means attached to said elongated member at spaced longitudinal points;
- and
- a cross member of a first cross sectional area having two ends which ends are attached respectively to two opposed sides of said channel, so that said cross member extends transversely across said channel, said cross member including at least one longitudinal portion having a smaller cross sectional area than said first cross sectional area which portion intersects said central axis and is adapted to cooperate with said slot-like aperture in said one end surface of said elongated member.

A motionless mixer includes
- a conduit defining a channel;
- an elongated member disposed longitudinally within said channel, said elongated member having a first end with a transverse end surface and a slot-like aperture formed in said end surface, said elongated member further including a first portion having a substantially constant first cross sectional area and a second portion having a cross sectional area greater than said first cross sectional area said second portion extending to said first end;
- a plurality of baffle means attached to said first portion of said elongated member at spaced longitudinal points;
- and
- a cross member attached across said channel in said conduit, said cross member being configured to fit within said slot in said second portion of said elongated member.
