Description

Technical Field

[0001] This invention relates to the field of titanium diboride powder preparation technology, specifically to a titanium diboride powder preparation apparatus for lithium battery manufacturing. Background Technology

[0002] In existing technologies, titanium diboride is often prepared by the borothermal method. Using titanium dioxide and elemental boron as raw materials under high temperature and vacuum catalysis, titanium diboride powder can be prepared at a high temperature and vacuum environment not exceeding 1100 degrees Celsius. This is a common preparation method for titanium diboride powder required for lithium battery manufacturing.

[0003] Since the preparation of titanium diboride via the borothermal method is mostly carried out in a reactor, and the purity of the selected titanium dioxide powder is required to be higher than 99%, titanium diboride tends to adhere to the reactor wall during the preparation process. In fact, this part of the titanium dioxide raw material does not participate in the preparation of titanium diboride, which has a certain impact on the yield of titanium diboride. Furthermore, the existing raw material mixing methods mainly use rod-shaped or fan-shaped stirring to mix the materials. During stirring, different materials need to be turned over as a whole or on the surface, which requires a lot of time. This type of stirring method cannot achieve rapid mixing between titanium dioxide and elemental boron, and the mixing process is inefficient. Therefore, we propose a powder preparation device for titanium diboride for lithium battery manufacturing. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention utilizes a vibrating assembly with a sleeve mounted on a lead screw. The sleeve rotates with the lead screw. The sleeve has a partition and a limiting plate. Inner plates are positioned between the partition and the limiting plates on both sides of the sleeve, allowing the inner plates to slide on the sleeve.

[0018] 2. In this invention, the spring can buffer the contact brush during the movement of the fixed sleeve and the movable sleeve, and reduce the contact impact force between the contact brush and the vessel body caused by material agglomeration on the side wall of the vessel body. This provides a certain degree of protection for both the contact brush and the vessel body. Furthermore, if the spring is damaged due to excessive buffering, it can be quickly replaced by disassembling the retaining bolt and the bolt hole. The operation is simple and the spring replacement is quick and convenient. Attached Figure Description

[0029] 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.

[0030] Please see Figure 1-9This invention provides a technical solution: a powder preparation device for titanium diboride used in lithium battery manufacturing, comprising a preparation container 1, a controller 2, a gas pressure gauge 3, and a servo motor 4. The output end of the servo motor 4 passes through the preparation container 1 and is fixedly connected to a ball screw nut assembly 5. A container wall contact assembly 6 is provided outside the ball screw nut assembly 5. A dispersion assembly 7 is provided at the end of the ball screw nut assembly 5 away from the servo motor 4. The container wall contact assembly 6 includes a movable sleeve 8, a fixed sleeve 9, and a contact brush 10. One end of the movable sleeve 8 is connected by a spring 11. One end of the sleeve is movably connected to the fixed sleeve 9, and the other end is movably connected to the contact brush 10. The side of the contact brush 10 away from the movable sleeve 8 is movably connected to the inner wall of the preparation container 1. An infrared receiver 140 is fixedly connected inside the fixed sleeve 9. An infrared transmitter 150 and a wireless transmission module 160 are fixedly connected inside the contact brush 10. The infrared receiver 140 and the wireless transmission module 160 are both electrically connected to the infrared transmitter 150. The wireless transmission module 160 is electrically connected to the controller 2. The gas pressure gauge 3 is movably connected to the preparation container 1.

[0031] The servo motor 4 drives the ball screw nut assembly 5 to rotate. On one hand, the screw 51 drives the ball nut 52 to move along the axial direction of the screw 51. On the other hand, the rotation of the screw 51 drives the dispersion component 7 to rotate. During the forward and reverse motion of the output end of the servo motor 4, the ball nut 52 drives the vessel wall contact component 6 to move along the axial direction of the screw 51. This causes the contact brush 10 inside the vessel wall contact component 6 to sweep off the material adhering to the inside of the vessel 11 after contacting the inner wall of the vessel 11. The material settles to the bottom of the vessel 11 under the action of gravity. When the screw 51 rotates axially, the dispersion component 7 rotates to achieve the dispersion and stirring of the material at the bottom of the vessel 11. The stirring of the material by the rotation of the dispersion component 7 can improve the material preparation rate. Moreover, the purpose of sweeping the vessel wall and dispersing the material by the dispersion component 7 can be completed with only one servo motor 4. This allows the purpose of improving the material preparation rate and reducing material loss to be achieved simultaneously in an energy-saving environment, effectively achieving the goal of reducing costs and improving output and product quality.

[0032] Preferably, the movable sleeve 8 has a first accommodating cavity 81 for accommodating the spring 110, and the fixed sleeve 9 has a second accommodating cavity 91 for accommodating the movable sleeve 8 and the spring 110. Each of the first accommodating cavity 81 and the second accommodating cavity 91 has a bolt hole 130 on one side. Each of the two bolt holes 130 is screwed with a retaining bolt 120, and one end of the retaining bolt 120 passing through the bolt hole 130 is engaged with the spring 110.

[0033] After screwing the retaining bolt 120 into the bolt hole 130, the end of the retaining bolt 120 inserted into the bolt hole 130 is inserted into the segment of the spring 110 and the spring 110 is locked in place. As the spring 110 moves between the fixed sleeve 9 and the movable sleeve 8, it can buffer the contact brush 10 and reduce the contact impact force between the contact brush 10 and the vessel body 11 caused by material agglomeration on the side wall of the vessel body 11. This provides a certain degree of protection for both the contact brush 10 and the vessel body 11. Furthermore, if the spring 110 is damaged due to excessive buffering, it can be quickly replaced by disassembling the retaining bolt 120 from the bolt hole 130. The operation is simple and the replacement of the spring 110 is quick and convenient.

[0034] Preferably, the contact brush 10 has a slot 102 inside for accommodating the infrared transmitter 150 and the wireless transmission module 160. A retaining plate 103 is expanded to one side of the slot 102. A tempered glass 104 is fixedly connected inside the retaining plate 103. An infrared receiver 140 is fixedly connected inside the retaining sleeve 9. The infrared transmitter 150 and the wireless transmission module 160 are fixedly connected inside the contact brush 10. Both the infrared receiver 140 and the wireless transmission module 160 are electrically connected to the infrared transmitter 150. The wireless transmission module 160 is electrically connected to the controller 2. The gas pressure gauge 3 is movably connected to the preparation container 1.

[0035] Since both the infrared receiver 140 and the wireless transmission module 160 are electrically connected to the infrared transmitter 150, and the wireless transmission module 160 is electrically connected to the controller 2, during the contact brush 10's contact with the vessel body 11, the infrared transmitter 150 emits an infrared signal in a straight line, which is received by the infrared receiver 140. If the movable sleeve 8 and the fixed sleeve 9 are relatively offset, this offset can easily cause the contact brush 10 to not adhere to the side wall of the vessel body 11, affecting the cleaning efficiency of the contact brush 10 on the vessel body 11. If the infrared signal emitted by the infrared transmitter 150 cannot be received by the infrared receiver 140, the wireless transmission module 160 will transmit the situation where the infrared transmitter 150 does not map the signal with the infrared receiver 140 to the controller 2, reminding personnel to perform maintenance.

[0036] Furthermore, the movable connection between the card slot 102 and the card plate 103 facilitates the maintenance of the infrared transmitter 150 and the wireless transmission module 160, and also ensures that floating materials do not enter the infrared transmitter 150 and the wireless transmission module 160.

[0037] Preferably, the ball screw nut assembly 5 includes a screw 51 and a ball nut 52. One end of the screw 51 is fixedly connected to the output end of the servo motor 4 via a connector 41, and the other end of the screw 51 is fixedly connected to the dispersion assembly 7. The ball nut 52 is disposed on the outside of the screw 51 and is movably connected to the screw 51.

[0038] Preferably, the dispersion component 7 includes a stirring and dispersion seat 71, a first dispersion blade 72, a second dispersion blade 73, and a vibration component 74. The stirring and dispersion seat 71 is fixedly connected to the end of the lead screw 51 away from the connector 41, and the first dispersion blade 72 and the second dispersion blade 73 are both fixedly connected to the outside of the stirring and dispersion seat 71.

[0039] During the rotation of the ball screw nut assembly 5, the ball nut 52 can move along the axial direction of the screw 51 and drive the vessel wall contact assembly 6 to move along the axial direction of the screw 51. During this process, the contact brush 10 inside the vessel wall contact assembly 6 is movably connected to the inner wall of the vessel 11 and cleans the vessel 11. At the same time, the rotation of the screw 51 drives the stirring and dispersing seat 71 to rotate. After the stirring and dispersing seat 71 rotates, it drives the first dispersing blade 72 and the second dispersing blade 73 to rotate to disperse and stir the material at the bottom of the vessel 11, thereby increasing the material preparation speed.

[0040] The oscillation assembly 74 includes a first mesh plate 741, a second mesh plate 742, and a sleeve 744. The middle part of the sleeve 744 is rotatably connected to the rod body of the corresponding lead screw 51. The second mesh plate 742 is provided with a plurality of insert rods 7421. A first trapezoidal platform 7442 and a second trapezoidal platform 7443 are respectively provided on both ends of the sleeve 744. The highest points of the first trapezoidal platform 7442 and the second trapezoidal platform 7443 are at the same height, and the lowest points of the first trapezoidal platform 7442 and the second trapezoidal platform 7443 are at the same height. The shapes of the first trapezoidal platform 7442 and the second trapezoidal platform 7443 are... Similar in shape, the sleeve 744 has a limiting plate 7441 on its outer wall, with the limiting plates 7441 respectively disposed on the outer walls of both ends of the sleeve 744. A partition 748 is disposed in the middle of the sleeve 744, the diameter of which is the same as the diameter of the limiting plates 7441 on both sides. Inner plates 749 are respectively disposed on the sleeve 744 on both sides of the partition 748, the diameter of which is larger than the diameter of the partition 748. Connecting rods 743 are disposed on the side edges of the inner plates 749 on both sides of the partition 748, and top plates 7432 are disposed on the outer ends of the connecting rods 743. The top plate 7432 and the corresponding inner plate 749 have the same diameter. Each side of the top plate 7432 has a through-hole 7431 in the middle. A lead screw 51 is rotatably connected to the through-hole 7431. A rotating opening 744 is provided in the middle of the sleeve 744 corresponding to the lead screw 51. The lead screw 51 is inserted into the corresponding rotating opening 7444. A first return spring 745 and a second return spring 746 are respectively sleeved on the sleeve 744 between the limiting plate 7441 and the inner plate 749 on each side of the sleeve 744. The first return spring 745 and the second return spring 746 are located on the corresponding inner plate. Between 749 and the limiting plate 7441, an inner rod 747 is provided on each side of the top plate 7432. The inner rod 747 faces the corresponding first trapezoidal platform 7442 and second trapezoidal platform 7443. A ball head 7471 is provided on the output end of each inner rod 747. Each ball head 7471 is slidably connected to the edge of the corresponding first trapezoidal platform 7442 and second trapezoidal platform 7443. The first mesh plate 741 is provided on the outer connecting rod 743 of the corresponding first trapezoidal platform 7442, and the second mesh plate 742 is provided on the outer connecting rod 743 of the second trapezoidal platform 7443.

[0041] Furthermore, a sleeve 744 is provided on the lead screw, which can rotate with the lead screw 51. The sleeve 744 is provided with a partition 748 and a limiting plate 7441. Inner plates 749 are respectively provided between the partitions 748 and the limiting plates 7441 on both sides of the sleeve 744, allowing the inner plates 749 to slide on the sleeve 744. A first return spring 745 and a second return spring 746 are respectively provided between each inner plate 749 and the corresponding limiting plate 7441. The return springs can push the inner plate 749 towards the partition 748. Each inner plate 749 is connected to a top plate 7432 via a connecting rod 743. The top plate 7432 is provided with a ball head 7471, and the ball head 7471 corresponds to a sleeve... The cylinder 744 is provided with a first trapezoidal platform 7442 and a second trapezoidal platform 7443. When the trapezoidal platforms rotate, they can push the top plates 7432 on both sides to move vertically, thereby driving the first mesh plate 741 and the second mesh plate 742 to move vertically. When the first mesh plate 741 and the second mesh plate 742 are close together, the insertion rod 7421 can be inserted. When they are far apart, the first mesh plate 741 and the second mesh plate 742 can vibrate as the sleeve 744 rotates, so that the titanium dioxide and boron on the first mesh plate 741 and the second mesh plate 742 can be more loose. Through the above arrangement, the titanium dioxide and boron can be mixed more easily and the mixing between titanium dioxide and boron can be accelerated.

[0042] To elaborate further, the first screen plate 741 has several holes, and a second screen plate 742 is provided below the first screen plate 741. The holes on the first screen plate 741 and the second screen plate 742 are not opposite each other. The second screen plate 742 is provided with a rod 7421, which can extend and retract within the holes of the first screen plate 741, so that the raw material will not be blocked in the hole.

[0043] At the same time, the contact brush 10 is movably connected to the inner wall of the vessel 11 and cleans the vessel 11. The material adhering to the inner wall of the vessel 11 can be swept to the bottom of the vessel 11 by the contact brush 10, thereby reducing the amount of material adhering to the inner wall of the vessel 11 that is not being prepared, improving the material preparation rate and the yield of finished products, and improving the purity of the material preparation. Furthermore, when the servo motor 4 drives the ball screw nut pair 5 and the dispersion component 7 to rotate simultaneously, it can effectively reduce energy consumption and reduce the cost of material preparation.

[0044] Preferably, the preparation container 1 includes a vessel body 11, a vessel cover 12 movably connected to the vessel body 11, and a base 17 disposed at the bottom of the vessel body 11.

[0045] The vacuum port 13 can be connected to a vacuum tube. Before material preparation, the vacuum port 13 is connected to the vacuum tube, and the vacuum pump is used to evacuate the inside of the vessel 11 through the vacuum port 13, so that the reaction can proceed smoothly and the material can be prepared smoothly.

[0046] Preferably, a support frame 15 is fixedly connected to the outside of the vessel body 11, the gas pressure gauge 3 is movably connected to the support frame 15, and the output end of the gas pressure gauge 3 passes through the vessel body 11 and communicates with the interior of the vessel body 11.

[0047] The gas pressure gauge 3 can perform gas pressure leak detection tests on the vacuuming operation inside the vessel 11 to avoid the situation where the vessel 11 is not in a vacuum environment before material preparation or the vessel 11 is not sealed during the material preparation process, which may lead to poor preparation.

[0048] Preferably, a lifting lug 16 is fixedly connected to one side of both the vessel body 11 and the vessel lid 12, and the lifting lug 16 is evenly distributed on the outer side of the vessel body 11 and the vessel lid 12.

[0049] The preparation container 1 can be transported by using a crane or other transportation equipment after being connected to the hook and the lifting lug 16. The preparation container 1 is convenient and quick to transport.

[0050] Preferably, the vessel wall contact components 6 are arranged in a circular array with the center line of the lead screw 51 as the baseline, and are evenly distributed on the outside of the ball nut 52. There are a total of six sets of vessel wall contact components 6, and the included angle between any two adjacent vessel wall contact components 6 is always 60°.

[0051] The vessel wall contact component 6 is set as a regular hexagon, so that the contact brush 10 inside the vessel wall contact component 6 can contact the inner wall of the vessel body 11 to the maximum extent, thereby achieving the most efficient scraping effect of the material on the inner wall of the vessel body 11, and further improving the material preparation quantity and the purity of the material preparation.

[0052] Preferably, the contact brush 10 has a screw head hole 101 inside, and the movable sleeve 8 is fixedly connected to a screw head 82 at the end away from the fixed sleeve 9, and the screw head 82 is adapted to the screw head hole 101.

[0053] The contact brush 10 can be removed from the movable sleeve 8 by screwing the screw head 82 into the screw head hole 101, which facilitates the maintenance of the contact brush 10 and the infrared transmitter 150 and wireless transmission module 160 inside the contact brush 10.
