Description
Technical field
The utility model belongs to the field of microflow control technique, and in particular to a kind of microfluid based on electroactive polymer is mixed
Clutch.
Background technology
In order to which fluid preferably mixes under minute yardstick, there are many document reports based on the more of different principle both at home and abroad
The microfluid mixer of type.But since the ratio of surface area and volume increased dramatically under minute yardstick, surface force and viscosity
The influence of power is occupied an leading position, and the effect of inertia greatly weakens.Therefore, microfluid in a mixer mixed effect be not it is fine,
Flowing time is also longer.
Microfluid mixer is broadly divided into active and passive type two major classes at present.It is active using additional excitation,
Periodically interference flowing field to be to reinforce the diffusion of molecule and the axial transport of quality, its main feature is that shorten mixing it is required when
Between, controllability is good, but needs external input energy, and structure is more complex.Passive use special microchannel or channel
In special construction, generate transverse mass transport or so that flow field be in unordered state, to reinforce mixed effect, its main feature is that tie
Structure is simple, but required time is grown, and process is uncontrollable.So coming from the structure and mixed performance of existing microfluid mixer
It sees, the two kinds of mixer of active and passive type can all enhance the mixing effect of microfluid in channel in certain degree
Fruit, but respectively have disadvantage.Therefore, there is an urgent need to can improve mixed effect and reduce the microfluid mixer of incorporation time.
Invention content
Insufficient existing for existing microfluid mixer in order to overcome, the utility model proposes one kind being based on electroactive polymer
Microfluid mixer, be provided with passive mixed cell and active mixed cell, combine active and passive type advantage.
Technical solution is as follows used by the utility model solves its technical problem：It is a kind of based on the micro- of electroactive polymer
Flow mixer, including three inlet tubes, a mixing chamber, one outlet pipe.Three inlet tubes are connected to mixing chamber；Institute
It is R that state mixing chamber, which be a radius, and the cylinder of a height of H is located at the centre of inlet tube and outlet, and it is passive to be equipped in mixing chamber
Mixed cell；The outlet is connected to mixing chamber, and outlet is made of five connecting pipes, the first straight pipeline and the first semicircle
Shape pipeline connects, and the first semi-circular pipe is connect with the second straight pipeline, and the second straight pipeline is connect with the second semi-circular pipe, and second
Semi-circular pipe is connect with third straight pipeline；Active mixed cell is equipped in the outlet.
The passive mixed cell is r by radius, four identical arch cylinder barrier compositions of width d, a height of H；
Arch cylinder barrier symmetrical configuration in the horizontal direction.
It is equipped on the inner wall of the first semi-circular pipe and the second semi-circular pipe in the active mixed cell electroactive
Polymer obstacle item；The surface and underface of first semi-circular pipe and the second semi-circular pipe are provided with metallic plate.
A kind of operation principle of microfluid mixer based on electroactive polymer described in the utility model is as follows：
A kind of fluid enters from intermediate inlet tube, and one other fluid enters from both sides inlet tube, and two kinds of fluids obtain tentatively
Mixing, encounters arch cylinder barrier after subsequently entering mixing chamber, can form vortex, the mixed effect of two kinds of fluids obtains again
It improves；Then, fluid enters outlet, and under DC Electric Field, the electroactive polymerization in semi-circular pipe inner wall is arranged
Object obstacle item will produce deformation, and constantly deformation can not only drive the movement of microfluid to electroactive polymer obstacle item, shorten micro-
The incorporation time of fluid, and can play the role of changing inside the outlet pipe structure, so that the mixed effect of fluid is obtained again
Enhancing.Therefore two kinds of fluids enter from microfluid mixer inlet tube, by mixing chamber, are flowed out from outlet, whole process one
It experienced and mix three times altogether, combine hybrid mode actively and passively, mixed effect is been significantly enhanced.
There is the utility model practical novelty, major advantage to be：
1. a kind of microfluid mixer based on electroactive polymer provided by the utility model is equipped with passive mixed cell
With active mixed cell, active and passive type advantage is combined, whole process experience mixes three times, and mixed effect is notable.
2. a kind of microfluid mixer based on electroactive polymer provided by the utility model, in the effect of extra electric field
Under, large deformation can constantly occur in the electroactive polymer obstacle item that semi-circular pipe inner wall is equipped with, make the knot of inner passage
Structure is constantly changed, and drives the movement of fluid, substantially reduces the time needed for mixing.
