Description

Technical Field

[0001] This invention relates to the field of hydraulic magnesium extraction technology, specifically to a hydraulic magnesium extraction device. Background Technology

[0002] In the process of producing magnesium by thermal reduction, crude magnesium is generally produced first, and then higher purity metallic magnesium is produced. When producing crude magnesium, it is collected in a collector. Then, the crude magnesium needs to be separated from the collector to complete the magnesium removal process. In order to reduce the labor intensity of workers, hydraulic equipment is used instead of manual operation.

[0003] For example, the Chinese patent with the number CN203080035U, "A Hydraulic Magnesium-Pulverizing Device", includes a hydraulic cylinder and a support plate mounted on the hydraulic cylinder. The hydraulic rod of the hydraulic cylinder passes through the support plate, and no fewer than three hooks are rotatably mounted on the support plate.

[0004] However, in the existing technology, the commonly used magnesium atomizing method is vertical magnesium atomizing. This method is only suitable for small tank collectors. When atomizing some large tank collectors, vertical magnesium atomizing not only fails to fix the large tank collector well, but also easily causes shaking during magnesium atomizing.

[0005] In addition, during magnesium removal, the hydraulic device needs to remove magnesium from collectors of different sizes. Therefore, when processing the coarse magnesium inside collectors of different sizes, the piston rod at one end of the hydraulic device starts to apply force, and the point of force will start to push the coarse magnesium away from the collector. However, due to the different sizes of the collectors, if the coarse magnesium is separated from the large tank collector, the force point of the coarse magnesium inside will be smaller. As a result, the separation efficiency is low, and the center of the separated coarse magnesium will be dented, and there will be coarse magnesium residue in the collector. Summary of the Invention

[0006] The purpose of this invention is to provide a hydraulic magnesium removal device to solve the problems mentioned in the background art. Because the hydraulic device needs to remove magnesium from collectors of different sizes, when processing coarse magnesium inside collectors of different sizes, the piston rod at one end of the hydraulic device applies force, pushing the coarse magnesium away from the collector. However, due to the different sizes of the collectors, if the coarse magnesium is separated from a large tank collector, the force point on the coarse magnesium inside will be smaller. Consequently, during separation, not only is the separation efficiency low, but the center of the separated coarse magnesium will also be concave, and coarse magnesium residue will remain inside the collector.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a hydraulic magnesium-powdering device, comprising a base plate and a support, wherein the bottom of the support is fixedly connected to the top of the base plate, a hydraulic cylinder is installed on one side of the support, a hydraulic lifting platform is installed on one side of the top of the base plate, a positioning mechanism is installed on the top of the hydraulic lifting platform, and a force-applying mechanism is provided on the inner side of the support;

[0008] The force-applying mechanism includes a connecting sleeve and a fixed column. The connecting sleeve is fixedly connected to one end of a hydraulic cylinder. The fixed column is fixedly connected to one end of the connecting sleeve. An installation groove is provided in the middle of the fixed column. A power component is provided on one side of the connecting sleeve. An installation plate is fixedly connected to one end of the fixed column. A limit plate is fixedly connected to the outer edge of the installation plate. A telescopic rod is slidably arranged inside the limit plate. A connecting plate is fixedly connected to one end of the telescopic rod. A first force-applying plate is fixedly connected to one side of the connecting plate. A rotating frame is rotatably connected to one side of the installation plate. A limit groove is provided at the corner of the rotating frame. A moving rod is slidably arranged inside the limit groove. One end of the moving rod is fixedly connected to the telescopic rod.

[0009] The power assembly includes a rotating rod, which is rotatably mounted inside a fixed column. One end of the rotating rod is fixedly connected to a rotating frame. A driven wheel is fixedly sleeved on the surface of the rotating rod, and a synchronous belt is sleeved on the surface of the driven wheel. One end of the synchronous belt is sleeved with a driving wheel.

[0010] Preferably, the width of the groove on the surface of the limiting plate is greater than the diameter of the moving rod, and the width of the telescopic rod is greater than the width of the groove. A baffle is fixedly connected to one end of the moving rod, and the diameter of the baffle is greater than the width of the limiting groove.

[0011] Preferably, a second force-applying plate is fixedly connected to one end of the rotating frame, and the first force-applying plate has an arc-shaped structure.

[0012] Preferably, a geared motor is fixedly installed on one side of the connecting sleeve, and the output end of the geared motor is fixedly connected to the drive wheel.

[0013] Preferably, the positioning mechanism includes a support frame and a support block. A lead screw is provided on the inner side of the support frame, and two movable frames are slidably installed on the surface of the support frame. Two sliding blocks are threaded onto the surface of the lead screw. The top of the sliding blocks is fixedly connected to the bottom of the movable frames, and the bottom of the support block is fixedly connected to the top of the movable frames. A connecting frame is fixedly connected to one end of the support block, and a limit track is fixedly connected to one end of the connecting frame.

[0014] Preferably, the two sliding blocks have opposite internal threads on their inner sides, and a servo motor is installed on one side of the support frame.

[0015] Preferably, the output end of the servo motor is fixedly connected to one end of the lead screw, and the one end of the lead screw is rotatably connected to the inner wall of the support frame.

[0016] Preferably, a collector is provided inside the positioning mechanism, and a lifting component is installed on the surface of the collector.

[0017] Preferably, the outer edge of one end of the collector is located inside the limiting track, and one end of the collector is located on top of the two support blocks.

[0018] Preferably, the bottom of the support frame is fixedly connected to the top of the hydraulic lifting platform.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, the rotating frame can be started to rotate under the drive of the power component. Under the drive of the rotating frame and the limiting action of the limiting plate of the limiting groove, multiple moving rods can be moved at the same time, thereby realizing the simultaneous unfolding of the telescopic rods inside the multiple limiting plates. Therefore, the positions of multiple first force plates can be adjusted at the same time, so that when the hydraulic cylinder starts to separate the coarse magnesium after startup, the coarse magnesium inside the collectors of different sizes can be subjected to uniform force, so as to avoid the center position of the coarse magnesium from being concave after separation. In addition, the uniform force on the coarse magnesium can also improve the separation efficiency.

[0021] 2. In this invention, the servo motor drives the lead screw to rotate, which in turn causes the two sliding blocks to move. Since the rotation direction of the lead screw and the thread direction on the inner side of the two sliding blocks are opposite, the two support blocks can be moved closer or further apart under the drive of the moving frame. This allows for accurate positioning and clamping when separating crude magnesium from collectors of different sizes, preventing the collector from shaking or moving during the separation process. This would cause the collector's axis to shift, affecting the normal separation of crude magnesium and reducing the separation efficiency.

[0022] 3. In this invention, the hydraulic lifting platform can be controlled and the positioning mechanism can be adjusted. Thus, when positioning collectors of different sizes, the axis of the collector can be controlled to be on the same horizontal straight line as the axis of the force application mechanism and the hydraulic cylinder. This ensures uniform force application and rapid separation when separating coarse magnesium. Attached Figure Description

[0031] 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 some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0032] Reference Figure 1-5 As shown: The hydraulic magnesium-powdering device includes a base plate 5 and a bracket 3. The bottom of the bracket 3 is fixedly connected to the top of the base plate 5. A hydraulic cylinder 1 is installed on one side of the bracket 3. A hydraulic lifting platform 6 is installed on one side of the top of the base plate 5. A positioning mechanism 7 is installed on the top of the hydraulic lifting platform 6. A force-applying mechanism 4 is provided inside the bracket 3.

[0033] The force-applying mechanism 4 includes a connecting sleeve 41 and a fixed column 42. The connecting sleeve 41 is fixedly connected to one end of the hydraulic cylinder 1, and the fixed column 42 is fixedly connected to one end of the connecting sleeve 41. An installation groove 421 is provided in the middle of the fixed column 42. A power component 48 is provided on one side of the connecting sleeve 41. An installation plate 43 is fixedly connected to one end of the fixed column 42. A limit plate 431 is fixedly connected to the outer edge of the installation plate 43. A telescopic rod 45 is slidably provided inside the limit plate 431. A connecting plate 453 is fixedly connected to one end of the telescopic rod 45. A first force-applying plate 46 is fixedly connected to one side of the connecting plate 453. A rotating frame 44 is rotatably connected to one side of the installation plate 43. A limit groove 441 is provided at the corner of the rotating frame 44. A moving rod 451 is slidably provided inside the limit groove 441. One end of the moving rod 451 is fixedly connected to the telescopic rod 45.

[0034] The power assembly 48 includes a rotating rod 482, which is installed inside the fixed column 42. One end of the rotating rod 482 is fixedly connected to the rotating frame 44. A driven wheel 484 is fixedly sleeved on the surface of the rotating rod 482. A synchronous belt 483 is sleeved on the surface of the driven wheel 484. A driving wheel 485 is sleeved on one end of the synchronous belt 483.

[0035] The width of the groove on the surface of the limiting plate 431 is greater than the diameter of the moving rod 451, and the width of the telescopic rod 45 is greater than the width of the groove. A baffle 452 is fixedly connected to one end of the moving rod 451, and the diameter of the baffle 452 is greater than the width of the limiting groove 441. A second force-applying plate 47 is fixedly connected to one end of the rotating frame 44, and the first force-applying plate 46 has an arc-shaped structure. A reduction motor 481 is fixedly installed on one side of the connecting sleeve 41, and the output end of the reduction motor 481 is fixedly connected to the drive wheel 485.

[0036] In this embodiment, during separation, a 500T hydraulic oil station is configured for the hydraulic cylinder 1, along with regulating valves, instruments, and oil pipes. As the hydraulic cylinder 1 moves, it begins to push the force application mechanism 4 to move, thereby using the hydraulic cylinder 1 to control the force application mechanism 4 to separate the coarse magnesium inside the collector 21. When the collector 21 is large, the force application mechanism 4 can be adjusted so that when the force application mechanism 4 applies force to the coarse magnesium inside the collector 21, the coarse magnesium inside the collector 21 is subjected to uniform force, thereby ensuring that the coarse magnesium can be separated from the inside of the collector 21 during separation.

[0037] During the adjustment process, after the geared motor 481 is powered on, it can drive the drive wheel 485 to rotate. When the drive wheel 485 rotates, it can drive the synchronous belt 483 to move, causing the driven wheel 484 to start rotating, which in turn can drive the rotating rod 482 to start rotating. As the rotating rod 482 rotates inside the fixed column 42, it can also drive the rotating frame 44 to start rotating together. Since the corner of the rotating frame 44 is an arc-shaped structure and a limit groove 441 is opened at the corner position, when the rotating frame 44 is rotating, the moving rod 451 can be moved by using the limit groove 441.

[0038] Then, when the moving rod 451 moves, it will also drive the telescopic rod 45 to move together. Since the telescopic rod 45 slides inside the limiting plate 431, the movement of the telescopic rod 45 will be limited by the limiting plate 431. Thus, driven by the moving rod 451 and limited by the limiting plate 431, the telescopic rod 45 will start to move in a straight line. In addition, when the moving rod 451 moves, the baffle 452 on one side can also play a limiting role to ensure that the moving rod 451 will not be tilted when it moves.

[0039] Finally, driven by the rotating frame 44, and limited by the limiting groove 441 and the limiting plate 431, multiple moving rods 451 can be moved simultaneously, thereby enabling the telescopic rods 45 inside the multiple limiting plates 431 to unfold together. Therefore, the positions of multiple first force plates 46 can be adjusted simultaneously, so that when the hydraulic cylinder 1 starts to separate the coarse magnesium, the coarse magnesium inside the collectors 21 of different sizes can be subjected to uniform force, so as to avoid the center of the coarse magnesium from being concave after separation. In addition, uniform force on the coarse magnesium can also improve the efficiency of separation. Example 2

[0040] Figure 6-7 As shown, the positioning mechanism 7 includes a support frame 78 and a support block 75. A lead screw 72 is provided inside the support frame 78, and two movable frames 74 are slidably mounted on the surface of the support frame 78. Two sliding blocks 73 are threadedly connected to the surface of the lead screw 72. The top of the sliding block 73 is fixedly connected to the bottom of the movable frame 74, and the bottom of the support block 75 is fixedly connected to the top of the movable frame 74. A connecting frame 76 is fixedly connected to one end of the support block 75, and a limit rail 77 is fixedly connected to one end of the connecting frame 76. The two sliding blocks 73 have opposite internal threads on their inner sides, and a servo motor 71 is installed on one side of the support frame 78.

[0041] In this embodiment, when the collector 21 is hoisted, the position of the support block 75 and the position of the limiting track 77 on the positioning mechanism 7 can be adjusted. This not only makes it easier to fix the collector 21, but also prevents the collector 21 from moving or shaking when separating crude magnesium, thus preventing the crude magnesium from being separated from the collector 21 quickly and normally after being subjected to force.

[0042] Therefore, when the servo motor 71 starts to drive the lead screw 72 to rotate, it can control the sliding block 73 to move. When the sliding block 73 moves, it will also drive the moving frame 74 to move together. When the moving frame 74 moves, it will be limited by the support frame 78, so that the moving frame 74 will slide on the surface of the support frame 78. This ensures that the moving frame 74 and the sliding block 73 will not deviate when they move.

[0043] Furthermore, since the internal threads of the two sliding blocks 73 on the surface of the lead screw 72 are in opposite directions, when the servo motor 71 is powered on, the two sliding blocks 73, together with the connected moving frame 74, can be controlled to move closer to each other or further away from each other, depending on the direction of rotation of the servo motor 71.

[0044] Then, as the sliding block 73 slides on the surface of the lead screw 72, the moving frame 74 slides on the surface of the support frame 78, thereby controlling the position of the two support blocks 75. Due to the arc-shaped structure of the support block 75, it is convenient to support and position one end of the collector 21.

[0045] Finally, when the support block 75 slides, the connecting frame 76 will also drive the limiting frame to move. Since the moving direction of the support block 75 is driven by the support frame 78 connected to it, the moving direction of the limiting track 77 is the same as that of the sliding block 73. Therefore, the protruding edge at the other end of the collector 21 will move to the inside of the limiting track 77, so that the limiting track 77 can fix the collector 21, thereby avoiding the collector 21 from shaking or moving during the separation process, which would cause the collector 21 to deviate from its axis, affect the normal separation of crude magnesium, and reduce the separation efficiency. Example 3

[0046] according to Figure 1 , Figure 6 and Figure 7 As shown, the output end of the servo motor 71 is fixedly connected to one end of the lead screw 72, and the other end of the lead screw 72 is rotatably connected to the inner wall of the support frame 78. A collector 21 is provided inside the positioning mechanism 7, and a lifting component 2 is mounted on the surface of the collector 21. One outer edge of the collector 21 is located inside the limiting rail 77, and the other end of the collector 21 is located on top of the two support blocks 75. The bottom of the support frame 78 is fixedly connected to the top of the hydraulic lifting platform 6.

[0047] In this embodiment, the hydraulic lifting platform 6 can control the support frame 78 to start lifting and lowering, and then adjust the height of the positioning mechanism 7 according to the size of the collector 21 to ensure that the support block 75 can stably contact the collector 21 when positioning the collector 21. In addition, when the positioning mechanism 7 is controlled by the hydraulic lifting platform 6, it can also ensure that the axis of the collector 21 is on the same horizontal straight line as the axis of the force application mechanism 4 and the hydraulic cylinder 1, so that the force can be applied evenly and the separation can be carried out quickly when separating coarse magnesium.

[0048] The method of use and working principle of this device: Connect the hoisting component 2 to the external hoisting device, so that the collector 21 can be placed inside the positioning mechanism 7 by using the hoisting component 2. After adjusting the positioning mechanism 7, the collector 21 with a can-shaped structure of different sizes can be positioned.

[0049] First, during positioning, the servo motor 71 drives the lead screw 72 to rotate, controlling the movement of the sliding block 73. As the sliding block 73 moves, it also moves the moving frame 74. The moving frame 74 is limited by the support frame 78, causing it to slide on the surface of the support frame 78. This ensures that the moving frame 74 and the sliding block 73 do not deviate during movement. Furthermore, because the internal threads of the two sliding blocks 73 on the surface of the lead screw 72 are in opposite directions, when the servo motor 71 is powered on, the direction of rotation of the servo motor 71 can control the two sliding blocks 73, along with the connected moving frame 74, to move closer to or further apart.

[0050] Then, as the sliding block 73 slides on the surface of the lead screw 72, the moving frame 74 slides on the surface of the support frame 78, thereby controlling the position of the two support blocks 75. Due to the arc-shaped structure of the support block 75, it is convenient to support and position one end of the collector 21.

[0051] In addition, the hydraulic lifting platform 6 can control the support frame 78 to start lifting and lowering, and then adjust the height of the positioning mechanism 7 according to the size of the collector 21 to ensure that the support block 75 can stably contact the collector 21 when positioning the collector 21. In addition, when the positioning mechanism 7 is controlled by the hydraulic lifting platform 6, it can also ensure that the axis of the collector 21 is on the same horizontal straight line as the axis of the force application mechanism 4 and the hydraulic cylinder 1.

[0052] Next, the separation of crude magnesium begins. The separation mechanism is adjusted according to the size of the collector 21. During the adjustment process, the geared motor 481 is energized and drives the drive wheel 485 to rotate. When the drive wheel 485 rotates, it drives the synchronous belt 483 to move, causing the driven wheel 484 to start rotating, which in turn drives the rotating rod 482 to start rotating. As the rotating rod 482 rotates inside the fixed column 42, it also drives the rotating frame 44 to start rotating together. Since the corner of the rotating frame 44 has an arc-shaped structure and a limit groove 441 is opened at the corner, when the rotating frame 44 rotates, the moving rod 451 can be moved by the limit groove 441. When the moving rod 451 moves, it will also drive the telescopic rod 45 to move together. Since the telescopic rod 45 slides inside the limiting plate 431, the movement of the telescopic rod 45 will be limited by the limiting plate 431. Thus, driven by the moving rod 451 and limited by the limiting plate 431, the telescopic rod 45 will start to move in a straight line. In addition, when the moving rod 451 moves, the baffle 452 on one side can also play a limiting role.

[0053] Finally, driven by the rotating frame 44, and limited by the limiting groove 441 and the limiting plate 431, multiple moving rods 451 can be moved simultaneously, thereby enabling the telescopic rods 45 inside the multiple limiting plates 431 to unfold together. Therefore, the positions of multiple first force plates 46 can be adjusted simultaneously, so that when the hydraulic cylinder 1 starts to separate the coarse magnesium after startup, the coarse magnesium inside the collectors 21 of different sizes can be subjected to uniform force.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
