Description
Technical field
The utility model is related to a kind of stirrer, more particularly to a kind of scalable stirrer of magnetic stirring apparatus.
Background technology
Chemistry and Bioexperiment during, magnetic stirring apparatus be chemistry or Bioexperiment during through commonly used instrument
Device, stirrer is then that it is put into the force application part that stirring action is played in vessel.The operation principle of magnetic stirring apparatus follows the storehouse of magnetic
Logical sequence law, magnetic stir bar is the agitating device by magnetic stirring apparatus field drives, by magnetic material core body and polytetrafluoroethyl-ne
Alkene shell is constituted.There is a rotatable magnet in magnetic stirring apparatus, will be driven when the magnet in magnetic stirring apparatus is rotated
Magnetic stir bar is rotated, so as to reach the purpose of stirring.
The stirrer that existing magnetic stir bar is generally used at present is all the rotatable magnetic of a fixed size
Rotor, it is in stirring movement, and material can follow magnetic stir bar to rotate simultaneously, and its shape is that section is oval magnetic patch,
The shortcoming of this stirrer is that mixing effect is poor, and agitated liquid is difficult to stir evenly in stirring viscosity larger liquid.And magnetic is stirred
Mix son additionally depends on magnetic stirrer axial direction chi to the mixing effect of material except container size, liquid are how many and viscosity influence is outer
Very little size, the big magnetic stirrer mixing effect of axial dimension is preferable in identical sample.But the axial chi of magnetic stirrer
The very little excessive rotary resistance for necessarily increasing magnetic stirrer unfavorable mixing effect, therefore select suitable for a user on the contrary
The magnetic stirrer of axial dimension is relatively difficult.
The content of the invention
The technical problems to be solved in the utility model is in view of the shortcomings of the prior art, proposing a kind of strong adaptability, stirring
The good stirrer of effect.
In order to solve the above-mentioned technical problem, the utility model proposes technical scheme be：A kind of magnetic stirring apparatus use can stretch
Contracting stirrer, the stirrer is made up of intersect at least two hollow connecting shafts, and magnet, institute are provided with the crosspoint
The two ends for stating connecting shaft are provided with stirring vane；The tail end of the stirring vane has an external screw thread, have in the connecting shaft with
The internal thread that the external screw thread coordinates, the tail end of the stirring vane is stretched into the connecting shaft, and passes through the internal and external screw thread
Coordinate and install, the head end of the stirring vane is curved；The stirrer outer wrap has polytetrafluoroethylene floor.
Such scheme, which is further improved, to be：The depth that the tail end of the stirring vane is stretched into the connecting shaft can
Arbitrarily adjusted between 1 to 30 centimetres.
Such scheme, which is further improved, to be：The outer surface of the polytetrafluoroethylene floor has screw thread or ring grain.
The scalable stirrer of magnetic stirring apparatus that the utility model is provided, its is simple in construction, easy to make, can pass through
Mould integrated injection molding completes, thus cost of manufacture is relatively low；Arc stirring vane structure design is simply ingenious, more fits
The radian of beaker, liquid with stirrer except moving in a circle in whipping process for it, and arc stirring vane realizes centrifugal mixer
Effect, the dynamics and intensity of stirring are increased significantly, it is ensured that the mixing quality and mixing evenness of material to be mixed；It can stretch
Contracting design causes the characteristics of stirrer has length adjustable, greatly increases stirring efficiency.
Brief description of the drawings
Fig. 1 is one preferred embodiment structural representation of the utility model.
Label is schematically as follows in figure：1- connecting shafts, 2- stirring vanes, 3- magnets.
Embodiment
Embodiment
The present embodiment provides the scalable stirrer of magnetic stirring apparatus, as shown in figure 1, hollow by two of right-angled intersection
Connecting shaft 1 is constituted, and magnet 3 is provided with crosspoint, and the two ends of connecting shaft 1 are provided with stirring vane 2；The tail end of stirring vane 2
With external screw thread, there is the internal thread coordinated with external screw thread, the tail end of stirring vane 2 is stretched into connection 1, and is led in connecting shaft 1
Cross internal and external screw thread and coordinate installation, the head end of stirring vane 2 is curved；Stirrer outer wrap has polytetrafluoroethylene floor.
The depth that the tail end of stirring vane 2 is stretched into connecting shaft 1 can arbitrarily be adjusted between 1 to 30 centimetres.By changing
Become size, can also realize the regulation of bigger distance.
The outer surface of polytetrafluoroethylene floor has screw thread or ring grain, quickly and efficiently can will stick to consolidating for flask inwall
Body sample is scraped off, and material recovery rate is high.
The present embodiment is cross-compound arrangement, can be as needed, increases to 3 axles, 4 axles etc. multiaxis, realizes preferably stirring effect
Really.
The utility model is not limited to the concrete technical scheme of above-described embodiment, in addition to the implementation, the utility model
There can also be other embodiment, be the protection domain of the utility model requirement.
