ABSTRACT:
An in-line blender is provided for mixing a single fluid or blending it with at least one other substance. The blender includes a conduit having a hollow interior disposed about a central axis and a shaft extending longitudinally through the conduit along the central axis. The blender also includes a plurality of stationary mixing stages extending in series along the central axis with each of the mixing stages defining a plurality of spiral channels within the hollow interior of the conduit. Each of the mixing stages includes a plurality of distinct segments extending in series along the central axis. The blender further includes means for adjusting both the angular and the axial position of each of the segments with respect to adjacent segments along the shaft. The in-line blender is assembled by securing a retaining device to one end of the shaft, placing a plurality of mixing elements on the shaft in sliding engagement therewith, and positioning each mixing element at a desired angular and axial position on the shaft. A holding device is secured on a second end of the shaft so as to hold the mixing element in compression between the holding device and the retaining device. The shaft and mixing elements are then placed within a conduit and secured therein so as to prevent relative axial movement therebetween. The retaining device may be utilized to either inject fluids into the line or to sample fluids flowing in the line. The retaining device includes a frame having an outer surface and a hollow interior defining an inner surface. The frame includes at least one opening extending radially from the inner surface to the outer surface. A tubular member extends though the opening into the hollow interior of the frame and the tubular member is releasably affixed to the frame in such a manner that the radial position of the tubular member is adjustable
