Preferred embodiments of the present invention will now be described in detail, examples of which are shown in the drawings. Wherever possible, the same reference numerals will be used in all the drawings to denote the same or similar parts.

[0048] Furthermore, although the terminology used in this invention is selected from commonly known and used terms, some terms mentioned in this specification may have been selected by the applicant in his or her judgment, and their detailed meanings are explained in the relevant sections of the description herein.

[0049] Furthermore, it is required that this utility model be understood not only through the actual terminology used, but also through the meaning implied by each term.

[0050] like Figure 2 and Figure 3 As shown, this utility model discloses a suspendable magnetic drive stirring device 100, which includes a drive unit, an isolation unit 110, and a working unit. The drive unit preferably includes a motor and reducer section 120 and an inner magnetic rotor 130. The motor and reducer section 120 is connected to the inner magnetic rotor 130 and is located below the isolation unit 110. An extended output shaft on the motor and reducer section 120 is connected to the inner magnetic rotor 130, and the motor and reducer section 120 has an extended output flange connected to the isolation unit 110.

[0051] The working unit may preferably include a spindle 140, a magnetic levitation component 150, a guide inner sleeve 160, a stirring rotor 170, a guide outer sleeve 180, and at least one magnetic structure 190.

[0052] The isolation unit 110 is installed outside the inner magnetic rotor 130. The spindle 140 is fixedly connected to the isolation unit 110, and the guide inner sleeve 160 is sleeved on the spindle 140 and pressed and fixed by fasteners (e.g., cap bolts). The lower part of the stirring rotor 170 is sleeved outside the isolation unit 110, and the guide outer sleeve 180 is pressed to the upper part of the stirring rotor 170 by the magnetic levitation component 150.

[0053] For example, the magnetic levitation component 150 can be provided with a threaded structure to fix the guide sleeve 180 in the stirring rotor 170. The isolation unit 110 and the stirring rotor 170 are preferably clearance-fitted.

[0054] The magnetic structure 190 is installed on the lower part of the spindle 140 and is arranged opposite to the magnetic levitation component 150. The magnetic structure 190 and the magnetic levitation component 150 form a repulsive magnetic levitation force, which keeps the stirring rotor 170 in a suspended state.

[0055] The mandrel 140 can preferably be connected by welding or threading to an end face with magnetic force, providing axial magnetic force (the direction of the magnetic force is parallel to the axis of the mandrel 140). This, together with the magnetic levitation component 150, forms a repulsive magnetic levitation force. By connecting the magnetic levitation component 150 to the stirring rotor 170 and the mandrel 140 to the isolation unit 110, the stirring rotor 170 is levitated. The stirring rotor 170 and the magnetic levitation component 150 can preferably be connected by threads, forming a repulsive magnetic force with the special magnetic end face (with a magnetic structure 190) on the mandrel 140.

[0056] For example, the mandrel 140 can be configured with a threaded connection structure and fixed to the isolation unit 10. Alternatively, the mandrel 140 can be configured with a special magnetic end face formed by threaded connection, welding, or integral machining.

[0057] Preferably, a mounting boss 141 is provided at the lower part of the mandrel 140, and the magnetic structure 190 is mounted on the upper end face of the mounting boss 141. The mounting boss 141 is fixedly connected to the isolation unit 110.

[0058] Here, the magnetic levitation component 150 can preferably be formed by encasing a magnetic material within a metal.

[0059] like Figure 3 As shown, in this embodiment, the mounting boss 141 is integrally formed with the lower part of the mandrel 140. The magnetic structure 190 with end face of the mandrel 140 cooperates with the magnetic levitation component 150 to realize the levitation function.

[0060] Or, such as Figure 4 As shown, in another embodiment, the mounting boss 141 is connected to the lower part of the spindle 140 in a separate fixing manner. The magnetic structure 190 on the end face is fixed to the spindle 140 by assembly, and can also cooperate with the magnetic levitation component 150 to realize the levitation function.

[0061] Based on this, the levitation capability can be changed by altering the configuration of the upper end face structure of the mandrel 140.

[0062] Here, the magnetic structure 190 and the mounting boss 141 can preferably be connected by threads, welded, or machined as a whole.

[0063] In addition, the suspendable magnetic drive stirring device also includes a guide and limiting component, which is mounted on the spindle 140 by fasteners. The fasteners are preferably cap bolts.

[0064] The isolation unit 110 is fixed (e.g., welded) to the container, with its upper side located inside the container. The stirring rotor 170 can be located at the bottom of the container, either eccentrically or centrally. Except for the motor and reducer 120 and the internal magnetic rotor 130, all other components are located inside the container. The stirring rotor 170 rotates under magnetic levitation, using impellers to propel the material, dispersing and mixing it, and creating axial and radial flow within the container.

[0065] According to the above structural description, the working process of this levitation magnetic drive stirring device is as follows: the motor and reducer 120 outputs rotational motion to the inner magnetic rotor 130, the isolation unit 110 is welded to the container, and the inner magnetic rotor 130 drives the stirring rotor 170 to rotate around the spindle 140. The magnetic levitation component 150 cooperates with the magnetic structure 190 on the spindle 140 to achieve levitation. The inner guide sleeve 160 and the outer guide sleeve 180 act as bearings, thus creating a levitation magnetic drive stirring device that realizes the function of dispersing and mixing materials.

[0066] This utility model is a suspendable magnetic drive stirring device that can efficiently stir and mix low-viscosity materials, and the use of magnetic levitation function can be selected according to the cleanliness requirements of the application scenario.

[0067] In summary, this levitation magnetic drive stirring device can reduce the contact area between the inner guide sleeve and the outer guide sleeve by utilizing levitation capability, thereby increasing the service life, stabilizing the working state of the stirring rotor, and reducing the risk of material contamination.

[0068] The stirring rotor uses magnetic levitation force to form a repulsive magnetic force with the spindle, which can effectively reduce the impact of external vibration, prevent the stirring rotor from jumping on the spindle, and improve the service life of the stirring rotor.
