Abstract
The utility model relates to a shearing and dispersing magnetic agitator, which is characterized by comprising a magnetic rotor, wherein a connecting shaft is arranged on the magnetic rotor; the magnetic rotor can freely rotate around the connecting shaft; and the other end of the connecting shaft is connected with a polyetrafluoroethylene shearing plate. The shearing and dispersing magnetic agitator is simple and smart in structural design, can simultaneously shear and disperse a material, and obtains better effects of shearing and dispersing.
Description
Technical field
The utility model relates to a kind of shearing and disperses magnetic stir bar.
Background technology
Magnetic stir bar is the agitating device that relies on the magnetic stirring apparatus field drives, is made of magnetic material core body and polytetrafluoroethylene (PTFE) shell.A rotatable magnet is arranged in the magnetic stirring apparatus, when the magnet in the magnetic stirring apparatus rotates, just can drive the magnetic stir bar rotation, thereby reach the purpose of stirring.Stir so magnetic stir bar directly can be put into to be stirred in the material, need not to build complicated agitating device, be particularly useful for vacuum reaction and confined reaction.
And existing magnetic stir bar all is a rotating magnet rotor, it is when stirring movement, material can be followed magnetic stir bar and be rotated simultaneously, and make the storeroom little relative movement, the dispersed with stirring performance is not good, especially for profit two-phase dispersion and emulsion and solid-liquid two-phase dispersion, dispersive property is poorer, and causes it to have tangible deficiency in actual applications.
Summary of the invention
The utility model provides a kind of relative motion, dispersive property shearing dispersion magnetic stir bar good, that also can shear the stirring material simultaneously of producing at above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
Shear and disperse magnetic stir bar, it is characterized in that: it comprises a magnet rotor, and described magnet rotor is provided with a connecting axle, and can freely rotate around this connecting axle, and the other end of described connecting axle is connected with a polytetrafluoroethylene (PTFE) shear plate.
Press such scheme, described magnet rotor is by the magnetic core body and be wrapped in the external polytetrafluoroethylene (PTFE) shell of magnetic core and constitute.
Press such scheme, described polytetrafluoroethylene (PTFE) shear plate main body is in the form of annular discs or closely discoid, and its periphery evenly is laid with a plurality of sheared edges.
Press such scheme, described sheared edge is fan-shaped, and the number of sheared edge is preferably 3-8.
Press such scheme, the outer of described polytetrafluoroethylene (PTFE) shear plate is bending-like, so that magnet rotor is when linking to each other with the polytetrafluoroethylene (PTFE) shear plate, the lower surface of magnet rotor does not exceed the flanging of polytetrafluoroethylene (PTFE) shear plate outer, and can freely rotate in the polytetrafluoroethylene (PTFE) shear plate.
Shearing of the present utility model disperses magnetic stir bar except a magnet rotor that can rotate with magnetic field, also has a polytetrafluoroethylene (PTFE) shear plate that does not rotate with magnetic field.When magnet rotor during by the field drives in the magnetic stirring apparatus, the polytetrafluoroethylene (PTFE) shear plate is not because of by field drives, and make a relative motion is arranged between magnet rotor and the polytetrafluoroethylene (PTFE) shear plate, be convenient to material is disperseed, and when disperseing, material is sheared, especially when the outer of polytetrafluoroethylene (PTFE) shear plate is bending-like, magnet rotor is when rotating the stirring material, form narrow slit between meeting and the polytetrafluoroethylene (PTFE) shear plate, so, material can be disperseed by powerful shearing force by this narrow slit the time, reaches good shearing dispersion effect.
The beneficial effects of the utility model: structural design is simply ingenious, can shear material when material is carried out dispersed with stirring, reaches better shearing dispersion effect.
Description of drawings
Fig. 1 and Fig. 2 are for shearing the schematic diagram that disperses magnetic stir bar;
Fig. 3 is for shearing the cutaway view that disperses magnetic stir bar;
Among the figure: 1 magnet rotor, wherein: 1-1 magnetic core body, 1-2 polytetrafluoroethylene (PTFE) shell; 2 polytetrafluoroethylene (PTFE) shear plates; 3 connecting axles.
The specific embodiment
As shown in Figure 1-Figure 3: shear and disperse magnetic stir bar to comprise a magnet rotor 1, described magnet rotor is provided with a connecting axle 3, and can freely rotate around this connecting axle, and the other end of described connecting axle is connected with a polytetrafluoroethylene (PTFE) shear plate 2.Described magnet rotor is by magnetic core body 1-1 and be wrapped in the external polytetrafluoroethylene (PTFE) shell 1-2 of core of magnetic material and constitute.Described polytetrafluoroethylene (PTFE) shear plate main body is in the form of annular discs, periphery evenly is laid with 6 fan-shaped sheared edges, the outer of described polytetrafluoroethylene (PTFE) shear plate is bending-like, so that magnet rotor is when linking to each other with the polytetrafluoroethylene (PTFE) shear plate, the lower surface of magnet rotor does not exceed the flanging of polytetrafluoroethylene (PTFE) shear plate outer.
During use, can disperse magnetic stir bar to be put in to fill this shearing waits to stir in the container of material, container is put on the magnetic stirring apparatus, open the magnetic agitation switch of magnetic stirring apparatus, then this shearing disperses magnet rotor in magnetic stir bar to begin to rotate under the field drives in magnetic stirring apparatus, but the polytetrafluoroethylene (PTFE) shear plate is not because of by field drives, and make a relative motion is arranged between magnet rotor and the polytetrafluoroethylene (PTFE) shear plate, be convenient to material is disperseed, the sheared edge of polytetrafluoroethylene (PTFE) shear plate can be sheared material when disperseing, especially when the outer of polytetrafluoroethylene (PTFE) shear plate is bending-like, magnet rotor is when rotating the stirring material, and can form narrow slit between the polytetrafluoroethylene (PTFE) shear plate, so, material can be disperseed by powerful shearing force by this narrow slit the time, reaches good shearing dispersion effect.
