TECHNICAL FIELD

[0001] The present application relates to the field of hydrogen magnesium element manufacturing process, in particular to a high-pressure-resistant magnetic transmission stirring structure and method for hydrogen magnesium element production process. BACKGROUND

[0002] In the hydrogen magnesium element preparation process, stirring needs to be carried out in a hydrogen environment. The traditional magnetic stirring equipment needs to provide a high-pressure sealed environment, and the inner wall is thicker than that of the normal pressure stirring, which increases the distance between the magnetic core and the magnetic sleeve, weakens the magnetism, and results in the need for larger volume of the magnetic core and the magnetic sleeve transmission. The large thickness of the sleeve is difficult to process and install, and the large volume of the magnetic core and the magnetic sleeve also causes space shortage, weight and cost increase and other problems. SUMMARY

[0003] In order to solve the above technical problems, a high-pressure-resistant magnetic transmission stirring structure and method for hydrogen magnesium element production process are disclosed in the present application. The technical scheme of the present application is as follows:

[0004] A high-pressure-resistant magnetic transmission stirring structure for hydrogen magnesium element production process, comprising a balance valve, a driving system, a magnetic transmission system, a reaction shell, a power shell, a flange plate and a stirring paddle.

[0005] Preferably, the balance valve comprises a valve body, a valve core, a push rod, a sealing metal sheet, a spring and a plug.

[0006] Preferably, the driving system comprises a motor, a driving wheel and a transmission belt.

[0007] The motor is fixed on the flange plate, the motor is connected to and controls the driving wheel, and the transmission belt is rotatably connected to the driving wheel.

[0008] Preferably, the magnetic transmission system comprises a magnetic ring, a magnetic core and an isolation shell.

[0009] The magnetic ring surrounds the magnetic core and can rotate relative to the magnetic core.

[0010] The isolation shell isolates the magnetic core from the magnetic ring.

[0011] The magnetic core passes through the flange plate and connects the stirring paddle.

[0012] A high-pressure-resistant magnetic transmission stirring method for hydrogen magnesium element production process, comprising the following steps:

[0013] S1, the material is put into the inside of the reaction shell;

[0014] S2, hydrogen is filled into the inside cavity of the reaction shell;

[0015] S3, the pressure inside the reaction shell is greater than the pressure inside the power shell; the balance valve operates, and the external gas enters the power shell;

[0016] S4, when the pressure inside the reaction shell is equal to the pressure inside the power shell, the balance valve stops operating, and the gas intake stops;

[0017] S5, repeat S2-S4 until the pressure inside the reaction shell reaches the set value and the pressure is balanced;

[0018] S6, control the main system to drive the magnetic transmission system to move, thereby driving the stirring paddle to rotate, and the material inside the reaction shell reacts.

[0019] Preferably, the S3 specific steps are as follows:

[0020] The pressure inside the reaction shell cavity increases, the pressure inside the power shell remains unchanged, and the pressure resistance of the isolation shell is much greater than the rigidity of the sealing metal sheet. The sealing metal sheet is pushed forward under pressure and exerts pressure on the push rod. When the pressure of the push rod exerted by the sealing metal sheet is greater than the spring force, the push rod drives the valve core to move, the side opening of the valve core coincides with the opening of the valve body shell, and the external gas enters the power shell through the gas inlet. The pressure inside the power shell increases.

[0021] Preferably, the S4 specific steps are as follows:

[0022] The pressure inside the power shell gradually increases. When the pressure inside the power shell rises to equal the pressure inside the reaction shell, the sealing metal sheet loses the thrust provided by the pressure difference, the valve core is reset due to the spring force, and the external gas intake stops.

[0023] Preferably, the S6 specific steps are as follows:

[0024] The motor rotates to drive the driving wheel, and then drives the transmission belt. Since the transmission belt is connected to the magnetic ring, the magnetic ring rotates with the transmission belt. The magnetic core rotates with the magnetic ring due to the magnetic field, and the stirring paddle rotates with the magnetic core due to the connection. The material begins to react in a high-pressure hydrogen environment.

[0025] The technical scheme of the present application can solve the technical problems in the prior art that in the production process of hydrogen magnesium, the traditional magnetic stirring equipment needs to provide a high-pressure sealing environment, the inner wall is thicker than that of the normal pressure stirring, which increases the distance between the magnetic core and the magnetic ring, weakens the magnetism, and causes the need for larger volume of the magnetic core and ring transmission, and the large thickness of the sleeve is difficult to process and install, and the large volume of the magnetic core and ring also causes space shortage, weight and cost increase, etc. The technical scheme of the present application is to design a new stirring transmission structure. In the manner of providing pressure to the opposite side, the inner wall thickness is greatly reduced, thereby reducing the distance between the magnetic core and the magnetic ring and improving the transmission efficiency. The balance valve with self-balancing function is arranged in the inner and outer cavities, which can automatically complete the balancing work when the pressure difference is generated between the inner and outer cavities.

[0057] The balance valve 1 comprises a valve body 1-1, a valve core 1-2, a push rod 1-3, a sealing metal sheet 1-4, a spring 1-5 and a plug 1-6.

[0058] The active system comprises a motor 2-1, an active wheel 2-2 and a transmission belt 2-3;

[0059] The motor 2-1 is fixed on the flange plate 6, the motor 2-1 is connected and controls the active wheel 2-2, and the transmission belt 2-3 is rotatably connected with the active wheel 2-2.

[0060] The magnetic transmission system comprises a magnetic ring 3-1, a magnetic core 3-2 and an isolation shell 3-3;

[0061] The magnetic ring 3-1 surrounds the magnetic core 3-2 and can rotate relative to the magnetic core 3-2;

[0062] The isolation shell 3-3 isolates the magnetic core 3-2 from the magnetic ring 3-1;

[0063] The magnetic core 3-2 penetrates through the flange plate 6 and is connected with the stirring paddle 7.

[0064] The structure of the embodiment is used to carry out the step of high-pressure-resistant magnetic transmission stirring in the hydrogen magnesium element production process.

[0065] S1, the material is put into the inside of the reaction shell 4; since the reaction shell 4 is sealed by the flange plate 6, at this time, the inside cavity of the reaction shell 4 is at normal pressure and is isolated from the atmosphere.

[0066] S2, hydrogen is filled into the inside cavity of the reaction shell 4;

[0067] S3, the pressure inside the cavity of the reaction shell 4 is greater than the pressure inside the inside cavity of the power shell 5; the pressure inside the cavity of the reaction shell 4 is increased, the pressure inside the cavity of the power shell 5 is unchanged, and the pressure resistance of the isolation shell 3-3 is much greater than the rigidity of the sealing metal sheet 1-4, the sealing metal sheet 1-4 is pushed to move and exerts pressure on the push rod 1-3, when the pressure of the sealing metal sheet 1-4 on the push rod 1-3 is greater than the elastic force of the spring 1-5, the push rod 1-3 drives the valve core 1-2 to move, the side opening of the valve core 1-2 is coincided with the opening of the valve body 1-1 shell, the external gas enters the inside cavity of the power shell 5 through the air inlet 1-7, and the pressure inside the inside cavity of the power shell 5 is increased.

[0068] S4, the pressure inside the inside cavity of the power shell 5 is gradually increased, when the pressure inside the inside cavity of the power shell 5 is increased to equal the pressure inside the inside cavity of the reaction shell 4, the sealing metal sheet 1-4 loses the pushing force provided by the pressure difference, the valve core 1-2 is reset due to the elastic force of the spring 1-5, and the external air intake is stopped.

[0069] S5, S2-S4 is repeated until the inside cavity of the reaction shell 4 reaches the set value and the pressure is balanced;

[0070] S6, the active system drives the magnetic transmission system to move, so as to drive the stirring paddle 7 to rotate, and the material in the inside cavity of the reaction shell 4 is reacted.

[0071] The motor 2-1 is controlled by the PLC to rotate the driving wheel 2-2, and then drive the transmission belt 2-3. Since the transmission belt 2-3 is connected with the magnetic ring 3-1, the magnetic ring 3-1 rotates with the transmission belt 2-3. The magnetic core 3-2 rotates with the magnetic ring 3-1 due to the magnetic field effect. The stirring paddle 7 is connected with the magnetic core 3-2 and rotates with it. The material starts to react in the high-pressure hydrogen environment.

[0072] In this embodiment, the inner wall thickness is greatly reduced in the manner of providing pressure to the opposite side, thereby reducing the distance between the magnetic core 3-2 and the magnetic ring 3-1 and improving the transmission efficiency. The self-balancing balance valve 1 is arranged between the reaction shell 4 and the power shell 5, which can automatically complete the balancing work when the pressure difference is generated inside and outside.

[0073] Under the same transmission force requirement, the volume of the magnetic core 3-2 and the magnetic ring 1-1 is reduced.

[0074] Under the same transmission force requirement, the processing difficulty is reduced.

[0075] The internal magnetic core 3-2 and the magnetic ring 3-1 are commonly used under the same torque, and only the external container needs to be replaced under different pressures, which is good in universality.

[0076] It should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
