The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail, so that technical staff's of the same trade understanding:

Shown in Fig. 1-5, label is represented respectively:

Add pipe, body 2, first mixed cell 3, plate 31, second mixed cell 4, plate 41, the 3rd mixed cell 5, plate 51, conical deflector 6.

Embodiment 1:

Shown in Fig. 1-4, a kind of flow mixer is provided in the present embodiment 1, this flow mixer comprises cylindrical hollow tube 2, the two ends of this body 2 form liquid feeding end and outlet end respectively.Tube cavity between liquid feeding end and outlet end then constitutes the hybrid chamber that fluid-mixing is used.In this hybrid chamber, be provided with one and be used for playing the mixing arrangement that two or more fluid mixes.In addition, before the mixing arrangement, the liquid feeding end of described body 2 also has the adding pipe that is communicated in its hybrid chamber.

Described mixing arrangement is made of three mixed cells, and to outlet end (fluid flow direction in the body 2 just), these three mixed cells are called first mixed cell 3, second mixed cell 4, the 3rd mixed cell 5 successively by liquid feeding end.These mixed cells constitute by the plate that polylith is set parallel to each other, and the both sides of all plates all are fixedly connected on the inwall of body 2, and all are parallel to body 2 length direction settings.In arbitrary mixed cell, each plate arranges with equidistant interval, and the multilayer gap that forms between the plate constitutes fluid passage.

Shown in Fig. 2-4, along the fluid flow direction in the body 2, any two adjacent mixed cells upwards were crisscross arranged angularly in the week of body 2.Specifically, the angle of cut is 90 ° between the plate 51 of the plate 31 of first mixed cell 3 at two ends and the 3rd mixed cell 5, and the angle of cut is 45 ° between the plate 41 of second mixed cell 4 and plate 31/ plate 51.Describe for simplifying, the angle of cut can be described as the angle of cut between the mixed cell between these plates.

In addition, along the fluid flow direction in the body 2, the distance between plates of first mixed cell 3, second mixed cell 4 and the 3rd mixed cell 5 is successively decreased successively, i.e. h1＞h2＞h3.Preferably, the distance between plates h3 of described the 3rd mixed cell 5 is 1/2 of first mixed cell, 3 distance between plates h1.

Further preferred, the distance between plates span should be in 0.5-20cm.
