Background technology
Current laboratory scientific research, teaching prepare whisker using hydro-thermal method, use autoclave alkali magnesium sulfate or sulphur more
Sour calcium pyroborate, equipment volume is big, be unfavorable for scientific research and teaching operating procedure, simultaneously because the larger each dress of the volume of reactor more
Doses also compares many, and scientific research is compared high with instruction cost.And mini-reactor small volume currently used in the market, operation side
Just, but due to that can not apply stirring, therefore the whisker problem of growing up can not be solved during whisker is prepared.It can not carry out simultaneously again
Several groups of experiments, to investigate under conditions of identical temperature, stir speed (S.S.), reaction ratio, catalyst, time etc. are a variety of to examination
Test the influence of result.
Agitating device is to make liquid, gas medium forced convection and mixed uniformly device.The type of agitator, size and
Rotating speed, all has an impact to distribution of the power of agitator between overall flow and turbulence pulsation.At present in industry and laboratory often
Use various types of agitators, according to the parameters such as the viscosity of material select suitable agitator can realize preferably processing or
Experiment effect.But the agitating device commonly used at present in application is that drive device drives rotary shaft to turn by mechanical transmission method combining
Dynamic, the stirring vane in rotary shaft realizes the stirring to material, and this stirring structure is simple, cost is low, torque is big, but is due to
Drive device couples with stirrer paddle machine driving, so certain influence is produced to the sealing in whipping process, simultaneously because
Rotor be installed in rotary shaft cause rotor dismounting and clear up it is also cumbersome, after long-term use material easily rotor or its
He connects sealing etc. and produces buildup, and the mixing to the later stage generates certain influence, there is inconvenience part.
Compared to above-mentioned conventional agitating device, also a kind of widely used magnetic stirring apparatus is stirred material at present
Mix, this agitator rotates the stirring realized to material by magnetically-actuated stirrer paddle, and drive device is to separate with agitating paddle
Two parts, be non-contact transmission, so the problems such as sealing of above-mentioned conventional whisk, cleaning can be avoided, installed, especially
It is with the obvious advantage in the stirring mixing of low capacity low viscosity material.
The content of the invention
The purpose of the present invention is in view of the shortcomings of the prior art that, there is provided a kind of magnetic stirring apparatus, solving should in industry
With and experiment in the container intracavity gas leakage of material stirring process, connection sealing, cleaning is difficult, the problem of installing trouble, together
When also improve common magnetic agitation effect, played the advantage of magnetic agitation, realized under the conditions of particular/special requirement to material
High-efficiency stirring.
In order to solve the above problems, the technical solution adopted by the present invention there is provided a kind of magnetic stirring apparatus, including stirring
Container and agitating paddle, the agitating paddle are ferrimagnet, and by magnet Magnetic Control, it is moved the agitating paddle.
Improved as one kind of this programme, be connected with drive mechanism above the agitating paddle, the drive mechanism being capable of band
Dynamic agitating paddle swings.
As another improvement of this programme, the drive mechanism is pendulum structure, makes it using clockwork spring to provide energy
Swing.
As the further improvement of this programme, a circle annular magnet, institute are arranged with outside agitating paddle above the stirring container
State and certain interval is left between annular magnet and agitating paddle.
As the further improvement of this programme, the annular magnet is arranged on the top edge of stirring container.
As the further improvement of this programme, the stirring container is hollow magnet.
As the further improvement of this programme, the agitating paddle end is provided with free-wheeling system.
As the further improvement of this programme, the free-wheeling system is propeller or wire netting, the propeller or iron wire
Net being capable of rotation.
As the further improvement of this programme, the agitating paddle can stretch.
As the further improvement of this programme, the agitating paddle is coated with one layer of decorative material layer.
Compared with prior art, by driving mechanisms control, it swings the agitating paddle of agitating device of the present invention, because
Agitating paddle is set to ferrimagnet, and surrounding is provided with a circle annular magnet again and surrounded, and annular magnet gives the suction of agitating paddle one
Gravitation so that agitating paddle is drawn close to annular magnet, when agitating paddle swings by the suction of annular magnet, is formed turning
Circle swing, reached the effect of agitated liquid, at the same agitating paddle end set propeller, the propeller can rotation, make
Agitating paddle revolution while, propeller again can rotation, accelerate stirring efficiency while again so that stir it is more thorough.
