Description
TECHNICAL FIELD
[0001] The present application relates to the field of magnetic stirring equipment, in particular to a magnetic drive reaction kettle for mixing and stirring. BACKGROUND
[0002] Compared with the traditional reaction kettle, the magnetic drive reaction kettle can realize completely sealed and zero leakage stirring transmission. Compared with the traditional reaction kettle, the magnetic drive reaction kettle does not have a penetrating stirring shaft, but instead has a mounting base for fixing the isolation sleeve and installing the entire magnetic drive device, thereby realizing the effect of complete sealing and zero leakage. The inside of the isolation sleeve is in communication with the inside of the reaction kettle, and the inside is rotatably assembled with an inner magnetic rotor, while the outside of the isolation sleeve is sleeved with an outer magnetic rotor. When the external driving device rotates with the outer magnetic rotor, the inner magnetic rotor can rotate with the stirring structure in the inside of the reaction kettle through the action of magnetic coupling.
[0003] The stirring structure of the magnetic drive reaction kettle is coaxially fixed with the magnetic rotor located in the inside of the kettle body, and then is sleeved on the surface of the positioning shaft located in the inside of the isolation sleeve. Under the limiting of the positioning shaft, the magnetic rotor can rotate with the stirring structure in the inside of the kettle body. However, in order to avoid the axial offset of the magnetic rotor and the stirring structure on the positioning shaft when the stirring structure rotates in the fluid due to the influence of fluid resistance, the magnetic rotor is fixed in the isolation sleeve by bolts, or the magnetic rotor and the stirring structure are magnetically limited outside the positioning shaft through a magnetic traction component. Although these two methods can effectively avoid the axial offset of the magnetic rotor and the stirring structure, it is very laborious and inconvenient to replace different stirring structures according to the different densities of the stirring medium when the stirring structure of many magnetic drive reaction kettles is equipped at the bottom of the kettle body.

[0037] The end face of each closed plate 26 close to each other is fixedly embedded with a group of second limiting magnetic blocks 28, and the opposite end faces of the two groups of second limiting magnetic blocks 28 are opposite in magnetic pole, and when the two closed plates 26 are combined, the mutual magnetic attraction of the two groups of second limiting magnetic blocks 28 can further improve the stability of the two closed plates 26 in closing the bottom of the disc sleeve frame 9.

[0039] Embodiment three: please refer to Figure 6 and Figure 9The embodiment is further illustration of other embodiments, and the magnetic limiting component is further arranged between the outer magnetic rotor 8 and the inner magnetic rotor 5, the magnetic limiting component comprises a magnetic ring 25 fixed at the bottom of the inner magnetic rotor 5, and the magnetic ring 25 does not contact the inner wall of the isolation sleeve 2, and a plurality of connecting rods 20 are radially rotatably arranged in the inner part of the outer magnetic rotor 8, the connecting rods 20 are fixedly provided with first limiting magnetic blocks 21 at one end extending into the inner part of the outer magnetic rotor 8, and the other end is provided with a deflection piece between the worm wheel disc 14.
[0040] When the second arc-shaped magnetic block 34 and the first arc-shaped magnetic block 7 are in the mutual magnetic attraction state, the first limiting magnetic block 21 and the magnetic ring 25 are also in the mutual magnetic attraction state, and when the worm wheel disc 14 rotates, the connecting rod 20 can be deflected with the first limiting magnetic block 21 through the deflection piece, so that when the second arc-shaped magnetic block 34 is no longer in the mutual magnetic attraction state with the first arc-shaped magnetic block 7, the opposite end faces of the deflected first limiting magnetic block 21 and the magnetic ring 25 will not be in the mutual magnetic attraction state.
[0041] The deflection piece comprises a bevel gear 19 fixedly sleeved on one end of the connecting rod 20 away from the first limiting magnetic block 21, and the outer surface of the outer magnetic rotor 8 is further rotatably sleeved with a bevel gear sleeve ring 18, the outer wall of the bevel gear sleeve ring 18 is fixedly provided with at least two curved rods 22 distributed at equal intervals in a circle, and the other end of the curved rod 22 is fixedly assembled with the worm wheel disc 14, and the outer wall of the disc sleeve frame 9 is further provided with a second arc-shaped groove 23 for sliding of the curved rod 22, when the worm wheel disc 14 rotates with the curved rod 22, the first limiting magnetic block 21 can be deflected through the transmission engagement of the bevel gear sleeve ring 18 and the bevel gear 19, and the deflection angle can be controlled through the gear ratio of the bevel gear sleeve ring 18 and the bevel gear 19.
[0042] Working principle: after the driving motor 12 is started, the rotating shaft 10 can rotate with the outer magnetic rotor 8 and the disc sleeve frame 9 outside the isolation sleeve 2 through the action of the synchronous gear 32 and the synchronous toothed belt 33, and the inner magnetic rotor 5 can rotate with the stirring impeller 6 in the inside of the isolation sleeve 2 through the mutual magnetic attraction of the first arc-shaped magnetic block 7 and the second arc-shaped magnetic block 34, so as to mix and stir the substances in the inside of the reaction kettle body 1.
[0043] When the stirring impeller 6 and the inner magnetic rotor 5 need to be replaced in the later stage, the personnel need to rotate the inner hexagonal nut 24 by using a wrench, the transmission engagement of the worm 16 and the worm disc 14 causes the worm disc 14 to be deflected inside the disc sleeve frame 9, at this time, since the pull rod 13 can only move radially inside the disc sleeve frame 9, the position adjustment of the pull rod 13 to the positioning column through the first arc-shaped slot 15 can cause the pull rod 13 to pull the limiting sleeve 35 to adjust the position of the second arc-shaped magnetic block 34, in the process of the limiting sleeve 35 and the second arc-shaped magnetic block 34 moving away from the center of the outer magnetic rotor 8, the limiting sleeve 35 and the second arc-shaped magnetic block 34 will be hindered by the stepped portion 17, so that the limiting sleeve 35 and the second arc-shaped magnetic block 34 are elastically deflected, and after deflection, the second arc-shaped magnetic block 34 and the first arc-shaped magnetic block 7 cannot be magnetically attracted to each other.
[0044] In the deflection process of the above worm disc 14, the worm disc 14 can also be deflected with the bevel gear sleeve ring 18, the transmission engagement of the bevel gear sleeve ring 18 and the bevel gear 19 can cause the first limiting magnetic block 21 to rotate inside the outer magnetic rotor 8, when the position adjustment of the limiting sleeve 35 and the second arc-shaped magnetic block 34 is completed, the first limiting magnetic block 21 and the magnetic ring 25 will not be magnetically attracted to each other at this time, that is, the inner magnetic rotor 5 will not be limited by the magnetic force at this time, and the personnel can quickly replace the inner magnetic rotor 5 and the stirring impeller 6 without resistance.
[0045] After the replacement is completed, the worm disc 14 is reset by rotating the worm 16 again, in the resetting process, the second arc-shaped magnetic block 34 and the limiting sleeve 35 will be elastically deflected and adjusted adaptively due to the first coil spring, so that the second arc-shaped magnetic block 34 and the first arc-shaped magnetic block 7 are magnetically attracted to each other again, and when the position resetting of the second arc-shaped magnetic block 34 is completed, the first limiting magnetic block 21 will also be magnetically attracted to the magnetic ring 25 again, so that the inner magnetic rotor 5 is limited by the axial magnetic force inside the isolation sleeve 2 through the mutual magnetic attraction of the first limiting magnetic block 21 and the magnetic ring 25, avoiding the inner magnetic rotor 5 from falling off during the mixing and stirring process of the material with the stirring impeller 6, and ensuring the stability of the high-speed rotation of the inner magnetic rotor 5 inside the isolation sleeve 2.
