Abstract

The utility model relates to a fluid mixer, which comprises an outlet pipe and at least two inlet pipes. The inlet pipe is communicated with the outlet pipes through a reticular pipeline; the reticular pipeline is composed of a plurality of pipelines which are mutually crossed and communicated; each adjacent pipeline is connected into a net; intersections between each pipeline form mutually communicated fork paths; the reticular pipeline comprises a plurality of the intersections and the fork paths. In the process that two or more than two fluids gather together and flow across the reticular pipeline, the fluids frequently change the flow direction, separate currents and gather currents a plurality of times, which results in collision between the fluids to achieve the purpose of full mixing. The utility model is suitable for fluid mixing with micro flow quantity in a laboratory.

Description

Flow mixer

The utility model relates to a kind of flow mixer, is used for the mixing of fluid in the continuous-flow process of two or more fluid, particularly tiny flow quantity.

In flow analysis, often two or more fluid (for example treating fluid measured and reaction reagent) fully need be mixed in flow process.Many siphunculus that the general employing of present this mixing contains a plurality of imports realize that a plurality of inlet tubes directly link to each other with same outlet, and two or more fluids feed from inlet tube separately, mix the back in intersection and discharge from outlet.Because only once of short duration crossing between each road fluid, therefore mix very insufficiently, be difficult to interpenetrate between the laminar flow regime fluid that particularly physical and chemical parameter such as density, viscosity difference is bigger, layering advection still after crossing in pipe is difficult to abundant mixing.For overcoming above shortcoming, the intersection space enlargement of people with many siphunculus arranged, in this space, install magnetic stirrer additional or install spherical or tabular flow-disturbing thing additional, make fluid produce disturbance.The shortcoming of this blender is a complex structure, and latter's mixed effect is also undesirable.The fluid used of lab analysis generally is tiny flow quantity (0.5-5ml/min) in addition, caliber is 0.5-2.0mm only, installs the diameter that agitating device must enlarge pipeline intersection additional, and memory effect increases, and prolonged analysis time, operating efficiency and sensitivity all reduce.

The purpose of this utility model provides a kind of simple in structure, high efficiency, and the flow mixer of low memory, it need not to add the flow-disturbing thing and multiple fluid is fully mixed in flow process.

The utility model flow mixer contains inlet tube and the outlet that interconnects, wherein inlet tube has two at least, communicate with tubes in line between said inlet tube and the outlet, said tubes in line is made up of several pipelines that communicate that cross one another, be linked to be grid between each adjacent channel, interface point between each pipeline forms the cross road, contains several the such interface point and cross road in the tubes in line.Tubes in line can contain single triangle, quadrangle, polygonal mesh or by the grid of above-mentioned at least two kinds of combination of shapes.This flow mixer also comprises the box-like body of being made up of base plate and cover plate, and tubes in line is provided in a side of the tubes in line groove of backplate surface, and cover plate and base plate fasten and with connecting elements locking, form tubes in line thereby the tubes in line groove is sealed by cover plate.Box body is provided with inlet tube interface and the outlet interface that communicates with the import and export of tubes in line respectively, feeds or discharges for fluid.

This flow mixer makes two or more fluid converge the back and flows into tubes in line, when fluid passes through in tubes in line with self pressure, change the flow direction continually owing to constantly run into the cross road, and shunt repeatedly and collaborate, cause constantly producing bump between the fluid, thereby two or more fluid is automatically fully mixed in flow process.This mixed closet need not to install additional flow-disturbing mechanism, and is simple in structure, the mixing efficiency height, and also memory effect is low.Mix efficient and sensitivity for analysis that can impact analysis work especially for the fluid of laboratory tiny flow quantity.

Further specify example structure of the present utility model below in conjunction with accompanying drawing.

Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 represent the various forms of tubes in line embodiment of the utility model flow mixer.

Fig. 7 is the boxlike flow mixer structural representation that contains the tubes in line groove.

In Fig. 1, Fig. 2, the flow mixer shown in Figure 3, the grid of tubes in line 3 is quadrilateral mesh.As depicted in figs. 1 and 2, fluid A and fluid B flow into tubes in line 3 from inlet tube 1-1 and 1-2 respectively, repeatedly shunt in tubes in line and collaborate, and reach abundant mixing, and mixed fluid AB is flowed out by outlet 2.Fig. 3 represents that A, B, three kinds of fluids of C flow into tubes in line 3 from inlet tube 1-1,1-2,1-3 respectively, and mixed fluid ABC is flowed out by outlet 2.Fig. 4 represents that the tubes in line 3 of flow mixer contains triangular mesh, and the tubes in line 3 of Fig. 5 flow mixer contains quadrangle, pentagon and hexagonal composite grid; Triangle and tetragonal composite grid are contained in webmaster road 3 among Fig. 6.Fig. 4,5,6 embodiment all contain two fluid inlet tubes 1-1,1-2, feed for fluid A and fluid B respectively, and mixed fluid ABC is flowed out by outlet 2.

Fig. 7 is the embodiment of the utility model boxlike flow mixer.Base plate 4 and cover plate 5 are by bolt 6 lockings, and tubes in line 3 is the pipeline grooves that are engraved on the base plate 4, and cover plate 5 is carried and being closed after base plate 4 and locking, and the tubes in line groove promptly is closed and reticulates pipeline.In the present embodiment, box body has two inlet tube interface 4-4,4-3 and an outlet interface 4-3, is used for the mixing of two kinds of fluids.
