Description

TECHNICAL FIELD

[0001] The present application relates to the field of magnetic transmission and fluid dynamics, in particular to a device for generating a specific spatial distribution of multipole magnetic field by using permanent magnets or electromagnets to drive the synchronous rotation of turbines on both sides to achieve non-contact torque transmission. BACKGROUND

[0002] Traditional fluid stirring or driving devices (such as mechanical impellers and propellers) usually require shaft seals, which have problems of leakage, wear and high maintenance costs. In applications requiring aseptic, non-polluting or closed transmission (such as chemical industry, biopharmaceuticals and food processing), the failure risk of mechanical seals is a major hidden danger.

[0003] Non-contact magnetic transmission technology (such as magnetic couplers) partially solves the sealing problem, but it usually generates a synchronous rotating magnetic field, which is single-function and mainly used for simple torque transmission.

[0004] Some existing magnetic stirring devices achieve non-contact stirring, but the generated flow field is mostly simple laminar or turbulent flow. Therefore, there is an urgent need in the field for a device capable of generating high-strength, high-stability and structure-controllable flow field to achieve efficient mixing, mass transfer, heat transfer or non-contact transmission. SUMMARY

[0005] To overcome the above-mentioned problems, the present application aims to overcome the deficiencies of the prior art and provide a turbine device with novel structure, high efficiency, no wear and no leakage.

[0008] Further, the driving end and the driven end interact through magnetic field without physical contact, and at least one set of stator magnet group is arranged on the opposite end of the driving end and the driven end, the stator magnet group is arranged by stator magnet body and permanent magnet or electromagnet according to specific polarity rule to generate a rotating multipole parallel magnetic field.

[0009] Further, the refrigerant pipeline is symmetrically arranged on the driving end and the driven end.

[0010] Further, the number of the stator magnet bodies is one, and the number of the permanent magnets is multiple.

[0011] Further, the permanent magnets can be replaced by electromagnets.

[0012] Further, the shell and the magnetic coupler are in detachable connection, and the refrigerant pipeline and the shell are also in detachable connection.

[0013] The application has the advantages that only magnetic transmission is used without other mechanical components, so that the cost is saved, the sealing is good, a complex and efficient vortex flow field is generated in the fluid, and the energy conversion efficiency and the control precision of the fluid are improved.

[0020] Referring to Figures 1-2 , the embodiment discloses a magnetic turbine device, which comprises a shell 1, a turbine 2 and a magnetic coupler 3. The turbine 2 is connected to the first main shaft 31 of the driving end 30 of the magnetic coupler 3, and the first main shaft 31 is connected with a gas suspension bearing 4. The second main shaft 33 of the driven end 32 of the magnetic coupler 3 is connected with a thimble bearing 5. The shell 1 is installed outside the magnetic coupler 3, and the top of the shell 1 is provided with a refrigerant pipeline 6. The refrigerant pipeline 6 is in communication with the inside of the turbine 2 through the shell 1.

[0021] ​The driving end 30 and the driven end 32 are interacted by magnetic field without physical contact, and each end of the driving end 30 and the driven end 32 is provided with at least one set of stator magnet group 7, which is arranged by stator magnet body 70 and permanent magnet 71 or electromagnet with specific polarity, for generating a rotating multi-pole parallel magnetic field.

[0022] The refrigerant pipeline 6 is symmetrically arranged on the driving end 30 and the driven end 32. The refrigerant pipeline 6 is used for inputting refrigerant, so that the refrigerant drives the turbine 2 to rotate, and at this time the driving end 30 of the magnetic coupling 3 can rotate, thereby generating magnetic vortex.

[0023] The number of the stator magnet body 70 is one, and the number of the permanent magnet 71 is multiple.

[0024] The permanent magnet 71 can be replaced by an electromagnet.

[0025] The shell 1 and the magnetic coupling 3 are in detachable connection, and the refrigerant pipeline 6 and the shell 1 are also in detachable connection, and the detachable connection can effectively reduce the maintenance cost and improve the maintenance convenience.

[0026] The working principle of the present application is that in the implementation process, one of the refrigerant pipelines 6 in the structure is connected with high-pressure refrigerant, and the other is connected with low-pressure refrigerant, so that the refrigerant gas entering the inside of the turbine 2 forms a high-low pressure difference airflow, and under the above-mentioned high-low pressure difference environment, the aerostatic bearing 4 is opened to enter the working state, at the same time, the refrigerant gas entering from the refrigerant pipeline 6 can drive the turbine 2 to operate, thereby driving the magnetic coupling 3 to rotate, under the action of magnetic vortex, the driven end 32 of the magnetic coupling 3 is opened to move, in this process, the aerostatic bearing 4 can protect and support the components of the driving end 30 of the magnetic coupling 3, improve the stability and safety of the overall operation, the thimble bearing 5 can reduce the friction of the components on the driven end 32, make the rotation more smooth, effectively reduce the energy consumption, and the cooperation of the aerostatic bearing 4 and the thimble bearing 5 greatly improves the operation efficiency of the present application, and also prolongs the service life of the machine.
