Abstract
Abstract A device for continuously mixing or reacting liquids has a cylinder with a plurality of spaced radial liquid inlets intermediate its ends for sequentially adding liquid and an outlet. An agitator having two or more shafts disposed parallel with the axis of said cylinder also has a plurality of blades fixed on the respective shafts for extremely restricting the mixture and agitation of the liquids on the axial direction but mainly drives the added liquids radially.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
222 words
A device for continuously mixing or reacting a plurality of liquids comprising: a cylinder having an inlet for receiving a first liquid at one end, and an outlet for discharging the same at the opposite end, a plurality of axially spaced, radially directed second liquid inlets on the wall of said cylinder, and being disposed intermediate of said first liquid inlet and said outlet, and an agitator comprising at least two rotatable shafts disposed within said cylinder, said shafts extending parallel to the longitudinal axis of said cylinder, each shaft including a plurality of axially spaced disc-shaped blades at respective positions in planes substantially common to the axes of said second liquid inlets, and said disc-shaped blades mounted on said shaft nearest said second liquid inlets and lying in the same plane therewith carrying means for impelling said second liquids entering the cylinder from said second liquid inlets in a radial direction relative to said cylinder to mix said second liquids sequentially with said first liquid; whereby, rotation of said shafts cause mixture and agitation of the liquids in directions radial to the longitudinal axis of the cylinder but restricts mixture and agitation of the liquids in an axial direction to effect sequential, complete and uniform mixing of the second liquids with the first liquid in the direction of said liquid outlet.
Claim 2
Independent Claim
222 words
A device for continuously mixing or reacting a plurality of liquids comprising: a cylinder having an inlet for receiving a first liquid at one end, and an outlet for discharging the same at the opposite end, a plurality of axially spaced, radially directed second liquid inlets on the wall of said cylinder, and being disposed intermediate of said first liquid inlet and said outlet, and an agitator comprising at least two rotatable shafts disposed within said cylinder, said shafts extending parallel to the longitudinal axis of said cylinder, each shaft including a plurality of axially spaced disc-shaped blades at respective positions in planes substantially common to the axes of said second liquid inlets, and said disc-shaped blades mounted on said shaft nearest said second liquid inlets and lying in the same plane therewith carrying means for impelling said second liquids entering the cylinder from said second liquid inlets in a radial direction relative to said cylinder to mix said second liquids sequentially with said first liquid; whereby, rotation of said shafts cause mixture and agitation of the liquids in directions radial to the longitudinal axis of the cylinder but restricts mixture and agitation of the liquids in an axial direction to effect sequential, complete and uniform mixing of the second liquids with the first liquid in the direction of said liquid outlet.
Claim 3
Dependent Claim
37 words
The devicE as claimed in claim 1, wherein said means for impelling said second liquids in a radial direction comprises circumferentially spaced, radial projections adjacent the peripheries thereof, in the path of the incoming respective second liquids.
Claim 4
Dependent Claim
46 words
The device as claimed in claim 2, wherein said shaft nearest said second liquid inlets further carries a plurality of axially spaced, disc-shaped blades at positions intermediate said blades carrying said impelling means to further restrict mixing and agitation of the liquids in an axial direction.
Claim 5
Dependent Claim
46 words
The device as claimed in claim 1, wherein said shaft nearest said second liquid inlets further carries a plurality of axially spaced, disc-shaped blades at positions intermediate said blades carrying said impelling means to further restrict mixing and agitation of the liquids in an axial direction.
