Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.It is illustrative to the description only actually of at least one exemplary embodiment below, is never used as to this practicality
New and its application or any restrictions used.Based on the embodiment in the utility model, those of ordinary skill in the art are not having
All other embodiments obtained under the premise of creative work are made, shall fall within the protection scope of the present invention.
As shown in Figure 1, the utility model embodiment provides a kind of fluid stirrer.The fluid stirrer includes：Mixing drum
10th, driving mechanism 20, multiple mixing components 30 and gear drive.Wherein, mixing drum 10 has stir chamber.Multiple stirring groups
Part 30 is spaced apart and arranged in stir chamber, and multiple mixing components 30 include an active mixing component 30 and at least one driven
Mixing component 30.Driving mechanism 20 is drivingly connected with active mixing component 30.Gear drive is arranged on active mixing component
Between 30 and driven mixing component 30 and/or between two driven mixing components 30 so that active mixing component 30 drive it is driven
Mixing component 30 is stirred.
Using the fluid stirrer in the present embodiment, in active mixing component 30 and the whipping process of driven mixing component 30
In, shear-mixed and convection current mixing are enhanced, accelerates the mixing between the liquid that viscosity characteristics differ larger, so that high viscous
Degree gel state fluid, heterogeneous fluid can be uniformly mixed with low viscosity fluid, solve fluid stirrer of the prior art
The problem of being not easy to mix viscosity characteristics difference larger fluid, while also improve stirring efficiency.
Specifically, each mixing component 30 includes rotation axis 31 and agitating paddle 32, and agitating paddle 32 is arranged on rotation axis 31
On.Rotation axis 31 on active mixing component 30 is drivingly connected with driving mechanism 20.
Specifically, the rotation axis 31 of multiple mixing components 30 is arranged in parallel.
Specifically, rotation axis 31 can set multigroup agitating paddle 32 along short transverse, and agitating paddle 32 includes multiple blades, multiple
Blade is symmetricly set on centered on rotation axis 31 in rotation axis 31.Preferably, symmetrically set on agitating paddle 32 in the present embodiment
Two blades are put.Preferably, outer diameter of two blades when rotating should be less than the internal diameter of mixing drum 10.In the present embodiment, two
Outer diameter of a blade when rotating is the internal diameter of 0.35-0.8 times of mixing drum 10.
Specifically, the spacing of the rotation axis 31 of two neighboring mixing component 30 be more than mixing component 30 blade length and
Less than two blades length and.
Specifically, the mixing surface of blade and the axial plane of rotation axis 31 have angle.In the whipping process of blender,
When mixing speed is low speed, the stirring flow direction of agitating paddle 32 is horizontal circumferential stream and axial stream, when mixing speed is high speed,
The stirring flow direction of agitating paddle 32 is radial flow and axial stream.Therefore, by setting the mixing surface of blade and the axial direction of rotation axis 31
The angle of plane changes the stirring plug-flow form of agitating paddle 32, so as to shorten the stirring used time, improves different viscosities characteristic
The mixed effect of liquid.
Preferably, the mixing surface of blade and the angle of the axial plane of rotation axis 31 should be set rationally in the present embodiment.
When the angle of setting is less than normal so that for agitating paddle 32 when at a high speed with stirring at low speed, the stirring flow direction of agitating paddle 32 is level
Circumferential direction stream and axial stream, the stirring plug-flow form of agitating paddle 32 does not change, thus can not improve mixed effect.When setting
When the angle put is bigger than normal, in the whipping process of blender, agitating paddle 32 and the contact area of fluid are maximum, thus agitating paddle 32
Larger resistance will be constantly subjected to, so as to which the extent of damage of blade can be increased.
Specifically, in order to enable a motor that multiple mixing components 30 to be driven to move, the gear drive in the present embodiment
Mechanism includes driving gear and at least one driven gear.Wherein, driving gear is arranged on active mixing component 30, and at least one
A driven gear is corresponded at least one driven mixing component 30 and set, and the gearratio of driving gear and driven gear is 1.
In this embodiment, it is preferred that there is provided a driven gears.As shown in Fig. 2 a, 2b, 2c and 2d, in the blender
Whipping process in, active mixing component 30 is identical with the rotating speed of driven mixing component 30, and direction is opposite.And two mixing components
30 remain correct phase, the gap being kept fixed, and are not in touch phenomenon mutually.
When two 30 synchronous rotaries of mixing component, high-viscosity gel shape fluid and low viscosity fluid or heterogeneous fluid with
Convection phenomena is generated between low viscosity fluid, and the fluid circled can be collided when contacting with each other, shears, squeezed
Pressure crushes, and destroys the circumferential cycle movement of fluid, both prevents eddy flow, also increase the axial shearing force between fluid, enhance
Mixed effect.
Specifically, fluid stirrer further includes controller 40, and controller 40 is used for controlling the movement of driving mechanism 20, and controls
Device 40 processed is electrically connected with driving mechanism 20.
Specifically, controller 40 includes permanent torque variable-frequency governor.It can be controlled and stirred by the perseverance torque variable-frequency governor
30 frequency conversion of component rotation is mixed, reduces the average torque and mill in 30 rotation axis 31 of active mixing component 30 and driven mixing component
Damage, so as to reduce maintenance capacity and maintenance cost, substantially increases 32 service life of agitating paddle.Using the perseverance torque variable-frequency governor,
When the Reynolds number for stirring initial stage fluid is smaller, the resistance that mixing component 30 is subject to is larger, thus mixing speed is relatively low, and stirs
Speed is 1-100r/min.With the progress of stirring, the Reynolds number of fluid constantly increases, and mixing speed is continuously improved.The perseverance is turned round
The time that square variable-frequency governor to reach identical miscible effect shortens, and energy consumption reduces, improve high-viscosity gel shape fluid with
The mixing efficiency of low viscosity fluid.
Specifically, driving mechanism 20 includes motor.
Using the fluid stirrer in the present embodiment, during the work time, fluid stirrer passes through permanent torque frequency control
Device controls the work of motor, and motor drives the driving gears in gear drive so that coordinates with driving gear
Driven gear also move therewith.With the transmission of gear drive, two be connected with driving gear and driven gear stir
It mixes component 30 to start to rotate, and the velocity of rotation of the two mixing components 30 is identical, direction is on the contrary, so that two stirring groups
Agitating paddle 32 on part 30 will not be touched mutually always.And the fluid stirrer is used, it adds different viscosities particular fluid and exists
Collision and shearing force when contacting with each other, so as to improve high-viscosity gel shape fluid and low viscosity fluid, heterogeneous fluid with
The mixed effect of low viscosity fluid, accelerates stirring efficiency, solves fluid stirrer of the prior art and is not easy to mix viscosity
The problem of characteristic difference larger fluid.
