Description

Technical Field

[0001] This invention belongs to the field of powder processing technology, specifically an electromagnetic levitation non-contact mixing device and its control method. Background Technology

[0002] Powder mixing technology is widely used in modern industry, covering almost all industries involving the processing of powder or granular materials. Its core function is to ensure that powders of different components can be uniformly mixed, thereby guaranteeing the quality, performance, and consistency of the final product. Taking lithium-ion batteries as an example, the front-end powder mixing process requires mixing multiple powder materials of different particle sizes or types to achieve uniform mixing. The dispersion and uniformity of the particulate active material directly affect the movement of lithium ions between the battery electrodes, and thus directly affect the quality of subsequent lithium-ion battery production and the performance of the product.

[0003] Existing technology uses ultrasonic stirring to mix various powder materials of different particle sizes or types. The ultrasonic transducer vibrates at a rated frequency at the bottom of the mixing tank to achieve ultrasonic stirring. However, this stirring method has certain drawbacks. Powder materials closer to the transducer are stirred more thoroughly, which can easily lead to uneven mixing. When the transducer vibrates, it comes into contact with the inner wall of the container, causing severe wear inside the container. Container residue that falls off mixes into the material, causing contamination of the mixed materials. Therefore, improvements are needed. Summary of the Invention

[0004] To address the problem of wear and tear on containers during torsion in existing technologies, the present invention provides an electromagnetic levitation non-contact mixing device, comprising: A control base, wherein a movable platform is provided on the upper surface of the control base; The torque components are in two sets, symmetrically arranged on both sides of the upper surface of the moving platform; The suspension component is located in the middle of the upper surface of the moving platform; The rotating drum was modified and placed inside the suspension component; The torque component includes: A rotating motor has a vertical connecting plate fixedly connected to its outer surface, and the bottom end of the vertical connecting plate is slidably connected to the inner cavity of the moving platform through a sliding groove. The transmission component is located at the top of the rotating motor shaft; The coupling magnetic block is located at the end of the conductive component that is furthest from the rotating motor.

[0005] Furthermore, the modified rotary drum includes: A container shell, wherein an inner stirring plate is uniformly arranged on the inner wall of the container shell; There are two side magnetic rings, symmetrically fitted on both sides of the outer surface of the receiving cylinder. The coupling magnetic block can drive the side magnetic rings to twist through magnetic force. The suspended magnetic rings are symmetrically arranged in the middle of the outer surface of the housing shell.

[0006] Furthermore, the levitation component includes: A control frame, the lower surface of which is engaged with the upper surface of the mobile platform; Rotary motors are symmetrically arranged on both sides of the top of the control frame, and rotating joints are inserted into the outer surface of the rotating motor shaft; Connecting plates are symmetrically arranged on both sides of the outer surface of the rotating joint, and a detector is provided at the end of the connecting plates away from the rotating joint; The magnetic sleeve is set on the outer surface of the connecting rotating plate. The inner diameter of the magnetic sleeve is larger than the outer diameter of the levitation magnetic ring to ensure that the modified rotating drum will not come into contact with the magnetic sleeve when it rotates. The charging base is located at the front of the control frame and is used to fix the lower connecting plate. The lower connecting plate is fixed to the moving platform by the charging base, and the rotating motor rotates the upper connecting plate by rotating the joint.

[0007] Furthermore, the charging dock includes: An extended bottom shell is provided, the lower surface of which is snapped into the upper surface of the mobile platform, the back of which is inserted into the outer surface of the control frame, and a charging port is provided at the front of the inner cavity of the extended bottom shell. The guide pads are evenly distributed on the upper surface of the extended bottom shell, and the outer surface of the guide pads is inserted into the outer surface of the lower connecting plate.

[0008] Furthermore, the magnetic outer sleeve includes: A guide ring shell, wherein the middle part of the outer surface of the guide ring shell is inserted into the outer surface of the connecting rotating plate, and the inner cavity of the guide ring shell is uniformly provided with recessed slots. An electromagnetic plate is provided, wherein the outer surface of the electromagnetic plate is uniformly arranged in the inner cavity of the conductive ring shell through recessed slots, and the inner cavity of the conductive ring shell is connected to the outer surface of the electromagnetic plate through connecting wires.

[0009] Furthermore, the magnetic outer casing also includes: Pressure-sensitive ball bearings, wherein the outer surfaces of the pressure-sensitive ball bearings are symmetrically arranged on both sides of the inner cavity of the guide ring shell through embedded grooves; An external display panel is attached to the outer surface of a guide ring shell. The inner cavity of the external display panel is fixedly connected to the inner cavity of a pressure-sensitive ball via a connecting wire. When the pressure-sensitive ball is subjected to pressure, it triggers the external display panel, causing the external display panel to turn into a red screen.

[0010] Furthermore, the conductive component includes: An electrically powered outer cylinder, wherein the left side of the inner cavity of the electrically powered outer cylinder is inserted into the outer surface of the rotating motor shaft via a socket; The plug-in end is symmetrically arranged on the right side of the inner cavity of the energized outer cylinder, and the outer surface of the plug-in end is plugged into the inner cavity of the coupling magnetic block. The cooling inner cylinder has its outer surface fixedly connected to the middle of the inner wall of the energized outer cylinder, and its right end is inserted into the inner cavity of the coupling magnetic block through an exhaust pipe.

[0011] Furthermore, the conductive component also includes: An external guide ring, the inner wall of which is sleeved with the outer surface of the energized outer cylinder; The power supply base has an extension wire fixedly connected to the middle of its inner cavity. The top of the extension wire is inserted into the bottom of the inner cavity of the outer guide ring. The inner cavity of the energized outer cylinder is inserted into the inner cavity of the plug-in end through an inner wire.

[0012] The beneficial effects of this invention are as follows: 1. This device can drive the powder inside to be stirred by twisting the container shell. As the container shell rotates, the side magnetic rings on both sides provide torque force, and the suspended magnetic ring in the middle can ensure that the container shell is suspended and does not come into contact with external objects. Therefore, when the container shell is centrifugally rotated, there will be no contact wear on the outside of the container shell. At the same time, the resistance on the container shell is greatly reduced, avoiding the problem of severe wear inside the container and the problem of container residue mixing into the material and contaminating the mixture.

[0013] 2. This device uses the electromagnetic force of the coupling magnetic block to twist the modified drum in the middle. When the rotation speed of the coupling magnetic block is too high, the coupling magnetic block will slip relative to the modified drum, thereby keeping the modified drum at the maximum limited speed for twisting, which plays a limiting and protective role for the modified drum. Since the modified drum does not feed back to the torque components on both sides due to centrifugal force when rotating, the device has higher stability and less noise during twisting.

[0014] 3. After the modified rotating drum is placed inside the merged guide ring housing, it is difficult to visually observe whether the modified rotating drum is in contact with the inner wall of the guide ring housing. Therefore, in order to facilitate the adjustment of the magnetic force of the guide ring housing, the guide ring housing has been improved. When the modified rotating drum comes into contact with the pressure-sensitive ball, it will exert a squeezing force on the pressure-sensitive ball, which will trigger the external display board. This allows the operator to intuitively adjust the magnetic force of the upper and lower electromagnetic plates, thereby ensuring that the modified rotating drum does not come into contact with any object for adjustment.

[0015] 4. The power supply base conducts electricity to the external guide ring through the extended wire. The external guide ring then supplies power to the plug-in end through the gasket structure in the middle of the energized outer cylinder, thereby enabling the coupling magnetic block to have magnetic attraction capability. In actual operation, the coupling magnetic block generates heat and continuously rises in temperature due to the power supply. At this time, the cooling inner cylinder will cool down the coupling magnetic block through the through-hole at the shaft center, thereby avoiding the problem of thermal damage to the coupling magnetic block.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an electromagnetic levitation non-contact mixing device, comprising: A control base 1 is provided, and a moving platform 2 is provided on the upper surface of the control base 1; Torque components 3, in two sets, are symmetrically arranged on both sides of the upper surface of the moving platform 2; The suspension component 4 is located in the middle of the upper surface of the mobile platform 2; Modify the rotating cylinder 5 and install it inside the suspension component 4; Torque component 3 includes: A rotating motor 31 is fixedly connected to a vertical connecting plate 32 on its outer surface. The bottom end of the vertical connecting plate 32 is slidably connected to the inner cavity of the moving platform 2 through a sliding groove. The transmission component 6 is located at the top of the rotating shaft of the rotating motor 31; The coupling magnetic block 35 is located at the end of the conductive component 6 away from the rotating motor 31.

[0020] Modified rotary drum 5 includes: The container shell 51 is provided with an inner stirring plate 52 evenly arranged on the inner wall of the container shell 51. There are two side magnetic rings 53, which are symmetrically sleeved on both sides of the outer surface of the receiving cylinder 51. The coupling magnetic block 35 can drive the side magnetic rings 53 to rotate through magnetic force. The levitation magnetic ring 54 is symmetrically arranged in the middle of the outer surface of the receiving shell 51.

[0021] Suspension component 4 includes: The lower surface of the control frame 41 is engaged with the upper surface of the mobile platform 2. Rotary motors 42 are symmetrically arranged on both sides of the top of the control frame 41, and rotating joints 43 are inserted into the outer surface of the rotating shaft of the rotary motors 42. Connecting plates 45 are symmetrically arranged on both sides of the outer surface of the rotating joint 43, and a detector 46 is provided at the end of the connecting plates 45 away from the rotating joint 43. The magnetic sleeve 47 is set on the outer surface of the connecting rotating plate 45. The inner diameter of the magnetic sleeve 47 is larger than the outer diameter of the levitation magnetic ring 54, ensuring that the modified rotating cylinder 5 will not come into contact with the magnetic sleeve 47 when it rotates. The charging base 44 is located at the front of the control frame 41 and is used to fix the lower connecting plate 45. The lower connecting plate 45 is fixed to the moving platform 2 by the charging base 44. The rotating motor 42 rotates the upper connecting plate 45 by rotating joint 43.

[0022] When using this device, open the suspension component 4, such as... Figure 2 As shown, powder is filled inside the housing shell 51, and then the housing shell 51 is sealed. Then, side magnetic rings 53 are fitted onto both ends of the housing shell 51 for reinforcement, and a floating magnetic ring 54 is fitted onto the middle of the housing shell 51. Then, the floating magnetic rings 54 on the upper and lower sides interlock to form a ring structure.

[0023] The assembled modified rotating cylinder 5 is placed inside the levitation component 4, with the levitation magnetic ring 54 facing the upper and lower magnetic sleeves 47. Then, the motor 42 rotates and closes the upper connecting plate 45 by twisting the rotating joint 43, so that the upper and lower magnetic sleeves 47 are connected. Subsequently, the charging base 44 supplies power to the magnetic sleeves 47 on both sides. The magnetic sleeves 47 on both sides are aligned with the axis of the modified rotating cylinder 5 by magnetic force. Since the inner diameter of the magnetic sleeves 47 is large, the modified rotating cylinder 5 is no longer in contact with the magnetic sleeves 47 at this time, and the modified rotating cylinder 5 is in a levitation state.

[0024] During processing, the mobile platform 2 controls the rotating motors 31 on both sides to slide horizontally, so that the coupling magnetic blocks 35 on both sides maintain a certain distance from the side magnetic rings 53 of the modified rotating drum 5. Then, the rotating motors 31 twist the coupling magnetic blocks 35 through the transmission component 6. Under the action of magnetic force, the side magnetic rings 53 are subjected to torque, which drives the receiving cylinder shell 51 to rotate. When the receiving cylinder shell 51 rotates, it will stir the powder inside through the inner stirring plate 52. During the rotation of the modified rotating drum 5, it never comes into contact with external objects.

[0025] After the powder inside the modified rotating drum 5 has been stirred for a period of time, the powder is processed. At this time, the upper connecting plate 45 is opened, the modified rotating drum 5 is removed, the side magnetic ring 53 and the suspending magnetic ring 54 are released, and the powder inside is poured out.

[0026] The charging base 44 mainly supplies power to the magnetic sleeve 47 of the levitation component 4. After the operation is completed, the magnetic sleeve 47 is de-energized and no longer exerts a magnetic force on the levitation magnetic ring 54.

[0027] Example 2, please refer to Figures 1-9The present invention provides a technical solution: based on embodiment 1, the charging base 44 includes: The extended bottom shell 441 has its lower surface snapped into the upper surface of the mobile platform 2, its back end inserted into the outer surface of the control frame 41, and a charging port 442 is provided at the front of the inner cavity of the extended bottom shell 441. The conductive pads 443 are evenly distributed on the upper surface of the extended bottom shell 441, and the outer surface of the conductive pads 443 is inserted into the outer surface of the lower connecting plate 45.

[0028] Magnetic jacket 47 includes: The guide ring shell 471 is inserted into the outer surface of the connecting plate 45 at the middle of its outer surface. The inner cavity of the guide ring shell 471 is uniformly provided with recessed slots. Electromagnetic plate 472, the outer surface of which is uniformly arranged in the inner cavity of conductive ring shell 471 through recessed slots, the inner cavity of conductive ring shell 471 is connected to the outer surface of electromagnetic plate 472 through connecting wires.

[0029] The magnetic jacket 47 also includes: Pressure-sensitive ball 473, the outer surface of the pressure-sensitive ball 473 is symmetrically arranged on both sides of the inner cavity of the guide ring shell 471 through embedded grooves; The external display panel 474 is snapped onto the outer surface of the guide ring shell 471. The inner cavity of the external display panel 474 is fixedly connected to the inner cavity of the pressure-sensitive ball 473 through a connecting wire. When the pressure-sensitive ball 473 is subjected to pressure, it will trigger the external display panel 474, causing the external display panel 474 to turn into a red screen.

[0030] Conductive component 6 includes: The energized outer cylinder 61 has its left side cavity connected to the outer surface of the rotating shaft of the rotating motor 31 via a socket. The plug-in end 63 is symmetrically arranged on the right side of the inner cavity of the energized outer cylinder 61, and the outer surface of the plug-in end 63 is plugged into the inner cavity of the coupling magnetic block 35. The cooling inner cylinder 64 has its outer surface fixedly connected to the middle of the inner wall of the energized outer cylinder 61, and the right end of the cooling inner cylinder 64 is inserted into the inner cavity of the coupling magnetic block 35 through an exhaust pipe.

[0031] Conductive component 6 also includes: An external guide ring 62 is connected to the outer surface of the energized outer cylinder 61 through which the inner wall of the external guide ring 62 is sleeved. The power supply base 33 has an extension wire 34 fixedly connected to the middle of its inner cavity. The top of the extension wire 34 is inserted into the bottom of the inner cavity of the outer guide ring 62. The inner cavity of the energized outer cylinder 61 is inserted into the inner cavity of the plug-in end 63 through the inner wire.

[0032] After the upper and lower connecting ring shells 471 surround the modified rotating cylinder 5, they generate a magnetic force on the modified rotating cylinder 5 through the working electromagnetic plate 472. However, during the power-on debugging process, the electromagnetic plates 472 on the upper and lower sides magnetically attract the modified rotating cylinder 5. At this time, the modified rotating cylinder 5 may come into contact with the upper and lower connecting ring shells 471, which will cause the modified rotating cylinder 5 to fail to maintain a suspended state when rotating. Therefore, pressure-sensitive balls 473 are provided on both sides of the connecting ring shells 471. When the modified rotating cylinder 5 comes into contact with the pressure-sensitive balls 473, it will exert a squeezing force on the pressure-sensitive balls 473. The pressure-sensitive balls 473 will then trigger the external display plate 474, allowing the operator to adjust the magnetic force of the upper and lower electromagnetic plates 472, thereby ensuring that the modified rotating cylinder 5 does not come into contact with any object.

[0033] The power supply base 33 conducts electricity to the external guide ring 62 through the extension wire 34. The external guide ring 62 then supplies power to the plug-in terminal 63 through the pad structure in contact with the middle of the energized outer cylinder 61, thereby enabling the coupling magnetic block 35 to have magnetic attraction capability. In actual operation, as the coupling magnetic block 35 generates heat and its temperature rises continuously due to the power supply, the cooling inner cylinder 64 will cool down the coupling magnetic block 35 through the through-hole at the shaft center, thereby preventing the coupling magnetic block 35 from being damaged by heat.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
