Background technology
Magnetic stirring apparatus is a kind of mixing apparatus being carried out agitated liquid by atwirl stirrer.Have the magnet of rotation under the base panel of magnetic stirring apparatus, stirrer is built-in with ferrimagnet, rotarily drives stirrer and rotates, thus realize agitating solution by magnet; Magnetic stirring apparatus is quieter and efficient, and is not exposed to extraneous drive disk assembly, so not fragile.And relative to other mixing plant, stirrer is also more easily cleared up and sterilization, magnetic stirring apparatus does not need lubricating oil, so can not reaction solution be polluted in whipping process, and even can use in container airtight completely, and do not need for rotating shaft of stirrer is in container upper shed, be therefore usually applied in high-precision test and test.
But existing magnetic stirring apparatus is subject to the restriction of power resources itself, stirrer itself does not have fixed support point, therefore random rolling self is done when rotating, hydromechanical profile is met so do not exist, usually be all be arranged to simple solid geometry shape or subsidiary one gimbal, this restriction causes magnetic stirring apparatus dealing with in bulk solutions and viscous liquid, perform poor, the ability of being uniformly mixed is restricted, can only apply and small-sized test chemical or experiment, need the magnetic stirring apparatus that a stirring capacity is stronger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vane type magnetic stirring apparatus, this magnetic stirring apparatus achieves the position rotating of stirrer, the impeller blade of hydrodynamic contour can be set on stirrer, greatly improve the stirring capacity of magnetic stirring apparatus, this magnetic stirring apparatus enable is applied in every field more widely.
The utility model is achieved in that a kind of vane type magnetic stirring apparatus, be made up of magnetic stirring apparatus body and stirrer two parts, described stirrer comprises passive rotating shaft and is arranged at least two blades on passive rotating shaft outer wall, described blade with passive rotating shaft core for center of circle annular array; Be provided with a stirrer permanent magnet in described passive rotating shaft, the outer end of described blade is provided with ferrimagnet; Be provided with in described magnetic stirring apparatus body by the active permanent magnet of driven by motor, described active permanent magnet rotates around active rotating shaft, match with blade in quantity and the position of active permanent magnet, be provided with location permanent magnet in described active rotating shaft, described location permanent magnet absorption stirrer permanent magnet makes the bottom surface of stirrer be positioned at container bottom.
The bottom surface of described stirrer is provided with an inner concave arc surface, and axle center, the bottom surface place of stirrer is provided with a back shaft, and the top of described back shaft slightly exceeds the outer of inner concave arc surface.
The material of described ferromagnetism material is iron, cobalt, nickel.
Described blade has two.
The utility model vane type magnetic stirring apparatus, is respectively provided with at the center of rotation of active permanent magnet and the center of rotation of stirrer the permanent magnet matched, achieves the position rotating of stirrer; Stirrer rotate time to container without particular/special requirement, as long as Flat bottom container can use this agitator and supporting stirrer to stir smoothly; After the rotary motion trace of stirrer is determined, can arrange the impeller blade of hydrodynamic contour on stirrer, greatly improve the stirring capacity of magnetic stirring apparatus, this magnetic stirring apparatus enable is applied in every field more widely.

Fig. 2 is the ac power waveform figure used in the present embodiment.
In figure: 1 magnetic stirring apparatus body, 2 stirrers, 11 motors, 12 are permanent magnet, 13 active rotating shafts, 14 location permanent magnets, 21 passive rotating shafts, 22 blades, 23 stirrer permanent magnets, 24 ferrimagnets, 25 inner concave arc surfaces, 26 back shafts initiatively.
Detailed description of the invention
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model statement.
Embodiment 1
As shown in Figure 1, 2, a kind of vane type magnetic stirring apparatus, be made up of magnetic stirring apparatus body 1 and stirrer 2 two parts, at least two blades 22 that described stirrer 2 comprises passive rotating shaft 21 and is arranged on passive rotating shaft 21 outer wall, described blade 22 with passive rotating shaft 21 axle center for center of circle annular array; Be provided with a stirrer permanent magnet 23 in described passive rotating shaft 21, the outer end of described blade 22 is provided with ferrimagnet 24, and ferrimagnet 24 is generally iron, cobalt, nickel; The active permanent magnet 12 driven by motor 11 is provided with in described magnetic stirring apparatus body 1, described active permanent magnet 12 rotates around active rotating shaft 13, match with blade 22 in quantity and the position of active permanent magnet 12, be provided with location permanent magnet 14 in described active rotating shaft 13, described location permanent magnet 14 adsorbs stirrer permanent magnet 23 makes the bottom surface of stirrer 2 be positioned at container bottom.
In use, stirrer 2 is put in container, container is placed on the platform of magnetic stirring apparatus body 1, because stirrer permanent magnet 23 and location permanent magnet 14 all have fixing magnetic pole, as long as therefore container bottom is comparatively smooth, then can ensure that the bottom surface of stirrer 2 is positioned on the axis of active rotating shaft 13 all the time, when motor 11 starts to rotate, stirrer 2 will rotate around the axis of active rotating shaft 13, because rotary motion trace is fixed, blade 22 on stirrer 2 can be set to meet the hydrodynamics impeller blade shapes stirring needs most, the surface area of blade own also can be larger simultaneously, so greatly improve the stirring capacity of magnetic stirring apparatus.
In the present embodiment, in order to reduce stirrer 2 when rotated, the frictional force of stirrer bottom surface and container, the bottom surface of described stirrer 2 is provided with an inner concave arc surface 25, to reduce contact area between the two, simultaneously, in order to ensure balance when rotating, axle center, the bottom surface place of stirrer 2 is provided with a back shaft 26, the top of described back shaft 26 slightly exceeds the outer of inner concave arc surface 25, usually this part exceeded is 0.1mm ~ 1mm, like this after stirrer 2 starts to rotate and reaches certain speed, the outer of inner concave arc surface 25 also disengages with container bottom, stirrer can be made to rotate while further reduction friction more to balance, and rotating speed slower or stressed unstable time, back shaft 26 is also unlikely to stirrer 2 is tumbled, be unlikely to the normal rotation having influence on stirrer.
Being at least two at the utility model Leaf 22 is because will ensure the uniform force of stirrer 2, energy normal rotation; But blade quantity is also too much unsuitable, too much blade quantity can cause each active permanent magnet may disturb when adsorbing blade, and have influence on normal stirring, therefore, in the present embodiment, described blade 22 has two.
