Description
Technical field
Magnetic stirring apparatus is used for being stirred for liquid material, the dissolving of accelerating solid material, accelerates entering for chemical reaction
OK.There is stability of rotation compared with mechanical agitator, good sealing effect, it is easy to operate the advantages that, biochemical in chemical industry, medical science, religion
Etc. industry is widely used.
Background technology
The general principle of magnetic stirring apparatus is exactly the rotation by magnetic force moving magnetic stirring bar (magnetic stir bar) and reached
To the purpose of stirring.The mode for promoting magnetic stirring bar is usually to drive permanent magnet to rotate with motor, in magnetic stirring apparatus
Use during, generally require to adjust different mixing speeds according to the difference of required stirring material, therefore just need to select
Stepless time adjustment motor.Compared with the motor of fixed rotating speed, the price of stepless time adjustment motor is of a relatively high, complicated, easily
Damage., it is necessary to which multiple motors, unstability also further rises while the cost of equipment increases in multi-joint magnetic stirring apparatus
It is high.Certainly also multigroup magnet can be driven to realize with a motor by transmission belt, but multigroup magnet in this case
Rotation keeps synchronous, can not individually control.
The content of the invention
The technical problem to be solved in the present invention is how to provide a kind of mechanical variable speed agitator, the magnetic stirring apparatus energy
Overcome disadvantages mentioned above, and it is simple in construction, operate, be easy to maintenance.
The present invention provides a kind of mechanical variable speed agitator, including driving wheel, driven pulley A, driven pulley B, transmission belt, can
Slide speed-governing rotor, permanent magnet and support, it is characterised in that：Driving wheel does not act on directly with the driven pulley B with magnet, and
To driven pulley B indirectly-actings by another driven pulley A so that in the case that active wheel speed keeps certain, by from
Changing to adjust the rotary speed of magnet for site is driven between driving wheel A and driven pulley B.
According to a kind of mechanical variable speed agitator provided by the invention, it is characterised in that：Driving wheel is connected with motor
Connect, or be directly installed on motor reel.
According to a kind of mechanical variable speed agitator provided by the invention, it is characterised in that：Driven pulley A and driven pulley B are
Structure with disk, circular cone or spherical design, and permanent magnet is installed on driven pulley B.
According to a kind of mechanical variable speed agitator provided by the invention, it is characterised in that：Between driving wheel and driven pulley A
It can be transmission belt, chain, gear or turbine type drive connection, driven pulley A rotation is driven by the rotation of driving wheel.
According to a kind of mechanical variable speed agitator provided by the invention, it is characterised in that：Driven pulley A and driven pulley B it
Between be driven by disc type, circular cone type transmission or the sphere formula kind of drive be driven, driven pulley A rotate during, pass through
Its site with driven pulley B interphase interactions is adjusted to change driven pulley B rotating speed, so as to adjust the rotating speed in magnetic field.
A kind of method of the mechanical variable speed agitator provided by the present invention due to have changed speed governing, it is not with speed governing electricity
Motivation is to adjust mixing speed but uses the method for mechanical speed governors to carry out speed governing, without the alignment circuit system of complexity, has
It is simple in construction, it is easy to maintenance, it is safe the advantages of, especially greatly carried in multi-joint magnetic stirring apparatus and determine speed motor
Utilization rate.
Embodiment
Embodiment 1：
In a kind of mechanical variable speed agitator, driving wheel 1, driven pulley 2, driven pulley 3 are installed on support 7, driving wheel 1 is logical
Transmission belt 5 to be crossed with driven pulley 3 to be connected, driven pulley 3 is connected by a transportable sliding rotor 6 with driven pulley 2, from
Permanent magnet 4 is installed on driving wheel 2.Driving wheel 1 drives driven pulley 3 to rotate when instrument is run, sliding rotor 6 and driven pulley 3, from
Friction drives driven pulley 2 to rotate between driving wheel 2, then obtains a rotatable magnetic field.By adjusting sliding rotor 6 and two

In a kind of mechanical variable speed agitator, driving wheel 1, driven pulley 2, driven pulley 3 are installed on support 7, driving wheel 1 is logical
Cross transmission belt 5 with driven pulley 3 to be connected, permanent magnet 4 is installed on driven pulley 2.Driving wheel 1 drives driven pulley when instrument is run
3 rotate, and are rotated between driven pulley 2, then obtain a rotatable magnetic field.Unlike embodiment 1, two driven
Wheel is designed as cone, and eliminates sliding rotor 6.Directly regulated the speed by changing the present position of transmission belt 5.It is in
Transmission belt 5 among two conical discs, when it is moved up, the rotary speed in magnetic field reduces, when moving down, the rotation in magnetic field
Rotary speed increases.
Embodiment 3：
In a kind of mechanical variable speed agitator, it is divided in support 7 for two parts, driving wheel 1, driven pulley is installed in a part
3, the hemispheric structure for passing power is wherein designed with driven pulley 3；Driven pulley 2 is installed on another part, it is driven
Permanent magnet is fixed with wheel 2.Support 7 with semiglobe can be movable within the specific limits around the hemisphere centre of sphere.Driving wheel 3 is logical
