Description

Technical Field

[0001] This invention belongs to the field of pebble bed high-temperature gas-cooled reactor technology, and specifically relates to a pipeline magnetic coupling lifting device for spherical elements. Background Technology

[0002] The pebble bed high-temperature gas-cooled reactor employs non-stop refueling technology, maintaining reactor operation through the continuous loading and unloading of spherical fuel elements. In existing technologies, after fuel elements are removed from the bottom of the core, they undergo pebble separation, burnup measurement, and multi-stage transfer and conversion equipment before finally returning to the core. Currently, fuel sphere lifting primarily relies on a pneumatic conveying system, which uses compressed helium to blow fuel spheres from the bottom to the top of the reactor. Specifically, the system can lift three fuel elements simultaneously at a time, and each reactor has four independent fuel sphere delivery pipelines to achieve continuous circulation.

[0003] However, this pneumatic conveying system presents several technical challenges. First, the conveying cycle is not an independent loop; airflow exchange occurs between the top and bottom of the stack and the primary loop, requiring specialized flow-blocking devices to isolate airflow interference. This results in a complex system structure and significant challenges in coordinated control. Second, pneumatic conveying relies on high-pressure helium and associated compression and purification equipment, leading to high system costs and operation and maintenance expenses. Furthermore, the pneumatic conveying method has limited precision in controlling the trajectory of fuel briquettes, making it susceptible to airflow fluctuations that affect conveying stability and thus hindering the improvement of overall refueling efficiency.

[0004] Therefore, how to simplify the system structure, reduce costs and maintenance difficulties, while improving the fuel ball delivery efficiency and control accuracy is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a pipeline magnetic coupling lifting device for spherical components, which can simplify the system structure, reduce the cost and maintenance difficulty, and improve the conveying efficiency of spherical components.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pipeline magnetic coupling lifting device for a spherical element includes a fixed tube body, a first magnetic component, a second magnetic component, and a power transmission mechanism;

[0008] The fixed tube is configured as a channel for conveying spherical components;

[0009] The first magnetic element is housed within the channel and is capable of sliding along the axial direction of the fixed tube.

[0010] The second magnetic component is connected to the power transmission mechanism;

[0011] The power transmission mechanism is disposed outside the fixed tube body, and the power transmission mechanism can drive the second magnetic component to move up and down along the height direction of the fixed tube body.

[0012] The first magnetic component and the second magnetic component are magnetically coupled, so that the second magnetic component can magnetically drive the first magnetic component to move synchronously in the channel along the axial direction of the fixed tube, thereby driving the spherical element to move along the channel.

[0013] Optionally, the power transmission mechanism includes a drive motor and a linear transmission assembly, and the second magnetic element is connected to the linear transmission assembly.

[0014] Optionally, the linear transmission assembly includes a driving pulley, a driven pulley, and a belt, the belt connecting the driving pulley and the driven pulley, and the output shaft of the drive motor connected to the driving pulley;

[0015] The belt extends along the axial direction of the fixed tube.

[0016] Optionally, it also includes a fixing member for fixing the second magnetic element, the fixing member being movable along the axial direction of the fixing tube body;

[0017] The second magnetic element is provided on the side of the fixing member facing the fixing tube, and the side of the fixing member facing away from the fixing tube is connected to the belt.

[0018] Optionally, the fixing member has a U-shaped groove on the side facing the fixing tube, and the second magnetic member is fixed to the groove wall of the U-shaped groove.

[0019] Optionally, a connecting plate is also included, the belt is fixed between the connecting plate and the fixing member, and the belt is fastened between the connecting plate and the fixing member by bolts.

[0020] Optionally, it also includes a support body, which is slidably disposed within the channel;

[0021] The support body and the first magnetic component can be linked together.

[0022] Optionally, the support includes a support body and a support surface, the support surface being disposed on the support body and used to contact the spherical element.

[0023] Optionally, the supporting surface is an arc surface, and the radius of curvature of the supporting surface is greater than the radius of curvature of the spherical element.

[0024] Optionally, the support body has a plurality of first through holes, the first through holes penetrating the top and bottom of the support body.

[0025] Optionally, the fixed tube body is further provided with an inlet pipe and an outlet pipe, the inlet pipe is inclinedly disposed on one side of the fixed tube body, and a switch assembly is also provided inside the inlet pipe;

[0026] The outlet pipe is located at the top of the fixed pipe body, and the outlet pipe is a bent pipe.

[0027] Optionally, it may also include a pipe fixing bracket, which is connected to the fixed pipe body.

[0028] Optionally, both the first magnetic component and the second magnetic component are electromagnets or permanent magnets.

The power transmission mechanism drives the second magnetic component to rise along the height direction of the fixed tube. Since the second magnetic component located outside the fixed tube is magnetically coupled with the first magnetic component located in the channel of the fixed tube, the second magnetic component can magnetically drive the first magnetic component to move synchronously in the channel of the fixed tube along the axial direction of the fixed tube, thereby driving the spherical element to move along the channel to realize the conveying of the spherical element.

[0055] In view of this, the core of the present invention is to provide a pipeline magnetic coupling lifting device, which can simplify the system structure, reduce the cost and maintenance difficulty, and improve the conveying efficiency of spherical components.

[0056] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Please refer to [the accompanying drawings]. Figures 1-7 .

[0057] Please refer to Figure 1 and Figure 5 The magnetic coupling lifting device for a spherical element disclosed in this embodiment of the invention includes a fixed tube 100, a first magnetic element 200, a second magnetic element 300, and a power transmission mechanism 400. The fixed tube 100 is configured as a channel for conveying the spherical element 900. The first magnetic element 200 is housed in the channel and can slide along the axial direction of the fixed tube 100. The second magnetic element 300 is connected to the power transmission mechanism 400. The power transmission mechanism 400 is disposed outside the fixed tube 100 and can drive the second magnetic element 300 to rise and fall along the height direction of the fixed tube 100.

[0058] The first magnetic element 200 and the second magnetic element 300 are magnetically coupled, so that the second magnetic element 300 can magnetically drive the first magnetic element 200 to move synchronously in the channel along the axial direction of the fixed tube 100, thereby driving the spherical element 900 to move along the channel.

[0059] When conveying the spherical element 900, the power transmission mechanism 400 needs to be activated. The power transmission mechanism 400 drives the second magnetic element 300 to rise along the height direction of the fixed tube 100. Since the second magnetic element 300, which is located outside the fixed tube 100, is magnetically coupled with the first magnetic element 200, which is located in the channel of the fixed tube 100, the second magnetic element 300 can magnetically drive the first magnetic element 200 to move synchronously in the channel of the fixed tube 100 along the axial direction of the fixed tube 100, thereby driving the spherical element 900 to move along the channel to realize the conveying of the spherical element 900.

[0060] Compared with the prior art, the spherical element pipeline magnetic coupling lifting device disclosed in the embodiments of the present invention has the following technical advantages:

[0061] 1) The spherical element 900 is transported by magnetic coupling of the first magnetic component 200 and the second magnetic component 300, which eliminates the need for complex mechanical transmission parts, simplifies the structure, and reduces the cost and maintenance difficulty.

[0062] 2) Magnetic conveying can effectively improve the conveying efficiency of spherical element 900.

[0063] The embodiments of the present invention do not limit the specific structure of the power transmission mechanism 400. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0064] As a specific embodiment of the present invention, the power transmission mechanism 400 disclosed in the present invention includes a drive motor 401 and a linear transmission assembly, wherein the second magnetic element 300 is connected to the linear transmission assembly, and the second magnetic element 300 is driven to rise or fall by the linear transmission assembly.

[0065] The embodiments of the present invention do not limit the specific structure of the linear transmission component. The linear transmission component can be a chain drive, rope drive, or lead screw guide drive, etc., and of course, it can also be other forms of transmission structure.

[0066] For specific embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 6 The linear transmission assembly disclosed in this embodiment of the invention includes a driving wheel 403, a driven wheel 404, and a belt 402, wherein the belt 402 connects the driving wheel 403 and the driven wheel 404, and the output shaft of the drive motor 401 is connected to the driving wheel 403.

[0067] It should be noted that the belt 402 is parallel to the axis of the fixed tube 100, that is, the belt 402 is set along the height direction of the fixed tube 100.

[0068] Start the drive motor 401. The output shaft of the drive motor 401 drives the drive wheel 403 to rotate. The drive wheel 403 drives the belt 402 to rotate. Under the action of the belt 402, the driven wheel 404 rotates synchronously, thereby driving the second magnetic component 300 to rise and fall along the axis of the fixed tube 100.

[0069] The axial direction of the fixed tube 100 is the same as the height direction of the fixed tube 100.

[0070] As a further embodiment, the pipeline magnetic coupling lifting device for the spherical element disclosed in this embodiment of the invention further includes a fixing member 500 for fixing the second magnetic element 300, the fixing member 500 being able to move along the axial direction of the fixing tube body 100.

[0071] In this design, a second magnetic element 300 is provided on the side of the fixing member 500 facing the fixing tube 100, and the side of the fixing member 500 facing away from the fixing tube 100 is connected to the belt 402. With this arrangement, the second magnetic element 300 is positioned close to the fixing tube 100, which can form good magnetic coupling.

[0072] The present invention does not limit the specific structure of the fastener 500. The fastener 500 can be a rectangular structure, a V-shaped structure, or other structures. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0073] As a specific embodiment of the present invention, the fixing member 500 disclosed in this embodiment has a U-shaped groove 501 on the side facing the fixing tube 100, wherein the second magnetic member 300 is fixed to the groove wall of the U-shaped groove 501. With this configuration, the U-shaped groove 501 forms a semi-enclosed magnetically conductive cavity. Fixing the second magnetic member 300 to its groove wall effectively guides and concentrates the magnetic field lines, allowing them to pass through the tube wall more efficiently and point towards the first magnetic member 200 inside, reducing the dissipation loss of the magnetic field inside the fixing member 500, thereby enhancing the effective magnetic coupling strength.

[0074] It should be noted that the U-shaped groove 501 has three sides of its groove wall. The second magnetic element 300 can be disposed on at least one side of the U-shaped groove 501, or at least two sides of the groove wall, or three sides of the groove wall. Those skilled in the art can make the arrangement according to actual needs.

[0075] To effectively secure the fixing member 500, the spherical element pipeline magnetic coupling lifting device disclosed in this embodiment of the invention further includes a connecting plate 800. A belt 402 is fixed between the connecting plate 800 and the fixing member 500. The connecting plate 800 and the fixing member 500 are fastened together by bolts 801. With this configuration, the belt 402, the fixing member 500, and the second magnetic element 300 are integrated into one unit, enabling synchronous lifting.

[0076] To effectively support the spherical element 900, the pipeline magnetic coupling lifting device for the spherical element disclosed in this embodiment of the invention further includes a support body 600. Please refer to [reference needed]. Figure 7 The support body 600 is slidably disposed in the channel, and the support body 600 and the first magnetic component 200 can be linked together.

[0077] In fact, the support body 600 is essentially an addition of a movable mechanical base and a physical position lock to the magnetic drive system, upgrading the original magnetic drive-magnetic maintenance mode to a more efficient and reliable magnetic drive-mechanical support mode. This structural design can greatly improve the practicality, safety and functionality of the entire pipeline magnetic coupling lifting device.

[0078] It should be noted that the support body 600 disclosed in the embodiments of the present invention includes a support body 601 and a support surface 602, wherein the support surface 602 is disposed on the support body 601 and is used to contact the spherical element 900.

[0079] As a further embodiment, the supporting surface 602 disclosed in this embodiment of the invention is an arc surface, wherein the radius of curvature of the supporting surface 602 is greater than the radius of curvature of the spherical element 900. This configuration enables stable and effective support for the spherical element 900.

[0080] To effectively filter debris and dust from the spherical element 900, the support 600 disclosed in this embodiment of the invention has multiple first through holes, which extend through the top and bottom of the support 600. With this configuration, debris and dust generated by the spherical element 900 can fall from the top to the bottom of the support 600 through the first through holes under the influence of gravity, vibration, or airflow, thus being effectively removed from the critical contact area. This maintains the cleanliness of the contact surface and significantly improves the reliability and service life of the magnetic coupling lifting device for the spherical element.

[0081] It should be noted that the fixed pipe body 100 disclosed in this embodiment of the invention is also provided with an inlet pipe 101 and an outlet pipe 102. The inlet pipe 101 is inclinedly disposed on one side of the fixed pipe body 100, and a switch assembly 1011 is also disposed inside the inlet pipe 101. The outlet pipe 102 is disposed at the top of the fixed pipe body 100, and the outlet pipe 102 is a bent pipe.

[0082] When it is necessary to insert a spherical element 900 into the inlet pipe 101, the switch assembly 1011 can be turned on. After a certain number of spherical elements 900 have been inserted into the inlet pipe 101, the switch assembly 1011 can be turned off. The bend in the pipe allows the spherical element 900 to slide to the next stage.

[0083] In order to fix the fixed tube body 100, the pipeline magnetic coupling lifting device for the shaped element disclosed in the embodiment of the present invention further includes a pipeline fixing bracket 700, wherein the pipeline fixing bracket 700 is connected to the fixed tube body 100 to achieve support and fixation of the fixed tube body 100.

[0084] As a specific embodiment, one end of the pipeline fixing bracket 700 disclosed in this invention can be set on the wall of the factory building, or on other fixing bodies that can support the lifting device.

[0085] It should be noted that the first magnetic component 200 and the second magnetic component 300 disclosed in the embodiments of the present invention can both be electromagnets or permanent magnets.

[0086] In order to prevent the first magnetic component 200 from being damaged during the lifting and lowering process, the outer surface of the first magnetic component 200 disclosed in the embodiments of the present invention is also covered with a wear-resistant layer 201.

[0087] To effectively filter debris and dust from the spherical element 900, the first magnetic component 200 disclosed in this embodiment of the invention is further provided with a second through hole, which penetrates the top and bottom of the first magnetic component 200. With this arrangement, debris and dust generated by the spherical element 900 can fall to the bottom sequentially through the first and second through holes under the influence of gravity, vibration, or airflow, thereby being effectively removed from the critical contact area and maintaining the cleanliness of the contact surface. This significantly improves the reliability and service life of the spherical element's pipeline magnetic coupling lifting device.

[0088] The first magnetic element 200 can be one or more. As a preferred embodiment of the present invention, the first magnetic element 200 disclosed in the present invention can be multiple, and the multiple first magnetic elements 200 are connected to each other as a whole, which is redundant to improve reliability.

[0089] It should be noted that the pipeline magnetic coupling lifting device for spherical elements disclosed in the embodiments of the present invention also includes a replacement housing, in which a first magnetic component 200 for backup is placed. When the first magnetic component 200 in use fails, the backup first magnetic component 200 can be replaced at any time.

[0090] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
