Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-4, the stirring device based on the magnetic-type stirring rod provided by the invention comprises:
the stirring device comprises a stirring motor 1, wherein a rotating shaft 11 is fixedly arranged at the output end of the stirring motor 1;
one end of the rotating shaft 11, which is far away from the motor, is inserted at the upper end of the motor fixing head 2 and is fixedly connected with the motor fixing head 2;
the stirring rod fixing head 3 is fixed or separated from the lower end of the motor fixing head 2 through attraction or repulsion of magnetic poles;
and the stirring rod 4 is tightly fixed with the stirring rod fixing head 3, and the central shaft of the stirring rod 4 and the central shaft of the stirring rod fixing head 3 are positioned on the same axial center. To the mounting means of puddler and stirring fixed head, the puddler fixed head has a through-hole along the center pin through, inserts the puddler in this through-hole to after adjusting the distance between puddler lower extreme to the test container bottom in advance, closely fixed puddler and puddler fixed head through modes such as gluing, in order to guarantee the eccentric problem of disappearance when the dead lever installation, the internal diameter of this through-hole slightly is greater than the external diameter of puddler, thereby reduced the error of installation.
As an embodiment of this application, the inside extension fixed mounting of 2 lower extremes of motor fixed head has a plurality of even annular distribution's first strong magnet 22, the inside extension fixed mounting in 3 upper ends of puddler fixed head has a plurality of even annular distribution's second strong magnet 31, the quantity of second strong magnet 31 with first strong magnet 22's quantity is the same. The mounting or dismounting of the agitating bar 4 is achieved by the mutual attraction or repulsion between the first strong magnet 22 and the second strong magnet 31. The first and second strong magnets of the present application are identical strong magnets.
Specifically, the number of the first strong magnets 22 and the number of the second strong magnets 31 are both even, and the polarities of the two adjacent first strong magnets 22 are opposite, and the polarities of the two adjacent second strong magnets 31 are opposite. Because the adjacent polarity of first strong magnet 22 and second strong magnet 31 is opposite, when the installation, through opposite poles attracting principle with puddler fixed head 3 and motor fixed head 2 fixed connection, when needs are dismantled puddler fixed head 3 from motor fixed head 2, only need rotate puddler fixed head 3 certain angle make first strong magnet 22 correspond rather than polarity the same second strong magnet 31 on, thereby realize the separation of puddler fixed head 3 and motor fixed head 2 under the principle that like poles repel each other, the efficiency of puddler 4 dismantlement has greatly been improved.
In addition, when using strong magnet to fix puddler 4, puddler fixed head 3 and motor fixed head 2 need adopt non-magnetic material to prepare, avoid the material to produce the influence to the magnetic field of strong magnet to influence the installation of puddler fixed head and motor fixed head.
