Description

Technical Field

[0001] This application relates to the field of graphite material compaction technology, and in particular to a crucible compaction device. Background Technology

[0002] In graphitization production lines, the crucible, as the core container, undergoes a crucial compaction process after loading, significantly impacting production efficiency and finished product quality. The loose packing density of graphite raw materials is typically low, leading to insufficient filling in individual crucibles. This not only limits production efficiency but also increases the sintering cost per unit product. Therefore, improving the loose packing density of graphite raw materials has become a pressing issue for the industry.

[0003] Currently, the most common compaction method is manual feeding, where operators manually tap or vibrate the crucible wall to make the internal material sink, and then add new material. Although this method is simple to operate, it generates a lot of dust during the tapping process, polluting the working environment and endangering the health of operators. In addition, the compaction effect of manual operation is limited and uneven, making it difficult to increase the loose density to the ideal level. Summary of the Invention

[0004] In order to efficiently, environmentally friendly and stably compact graphite materials in crucibles, this application provides a crucible compaction device.

[0005] This application provides a crucible compaction device, which adopts the following technical solution: A crucible compaction device, comprising: frame; A support platform, mounted on the frame, is used to support the crucible to be vibrated; A vibration generating mechanism is located below the support platform and is used to generate high-frequency vibration to compact the material in the crucible; An elastic damping component is disposed between the support platform and the frame to absorb vibration energy, reduce noise, and reduce impact on the frame; A clamping and positioning mechanism, mounted on the frame, is used to fix the outer wall of the crucible to prevent it from shifting or tipping over during the compaction process; The frame is equipped with a dust cover, which is liftable and positioned above the crucible to seal the top opening of the crucible during the compaction process to prevent graphite material from spilling out.

[0006] By adopting the above technical solutions, the vibration generating mechanism generates high-frequency vibration, which causes the material in the crucible to be squeezed and fill the gaps under the vibration, thereby increasing the loose packing density of graphite. The elastic damping component can absorb the vibration energy generated by the vibration generating mechanism, reduce the transmission of vibration to the frame and the ground, and achieve the effect of vibration reduction and noise reduction. The clamping and positioning mechanism can firmly fix the outer wall of the crucible, preventing the crucible from shifting or tipping over during the compaction process, thus improving the safety and stability of operation. The dust cover on the frame can close the top opening of the crucible during the compaction process, preventing graphite material from overflowing, avoiding dust pollution of the working environment, and protecting the health of operators.

[0007] Optionally, the clamping and positioning mechanism includes a rotating shaft connected to the bearing platform; a baffle is fixed along the length of the rotating shaft, and a fixing clamp is detachably connected to the side of the baffle near the crucible; A driving component is provided between the baffle and the frame. The driving component can drive the baffle to move closer to or further away from the crucible, so as to clamp or release the crucible by the fixed clamping block.

[0008] By adopting the above technical solution, when it is necessary to fix the crucible, the driving component drives the baffle to move closer to the crucible, and the fixing block will press against the outer wall of the crucible, thereby firmly fixing the crucible on the bearing platform and preventing it from shifting or tipping over during the compaction process, thus improving the safety and stability of the operation. When the compaction operation is completed and it is necessary to remove the product from the crucible, the driving component drives the baffle to move away from the crucible, and the fixing block separates from the outer wall of the crucible, making it convenient to remove the crucible. In addition, the fixing block and the baffle are detachably connected, which makes it easy to replace the fixing block of different specifications to adapt to different crucibles, and allows for quick and convenient replacement.

[0009] Optionally, the driving component includes a driving screw that is rotatably connected to the frame in a vertical direction; the frame is provided with a sliding groove in a vertical direction, and a lifting block is slidably connected in the sliding groove, the lifting block being threadedly connected to the driving screw; pull ropes are fixed on both sides of the baffle, and the other end of the pull ropes is fixed to the lifting block.

[0010] By adopting the above technical solution, when the drive screw rotates, the lifting block connected to it by threads will slide vertically in the sliding groove of the frame. Since the other end of the pull rope fixed on both sides of the baffle is fixed to the lifting block, the vertical movement of the lifting block will drive the baffle to rotate around the rotation axis through the pull rope. When the lifting block moves upward, the pull rope pulls the baffle to rotate towards the crucible, so that the fixed clamping block presses against the outer wall of the crucible, thereby clamping and fixing the crucible. When the drive screw rotates in the opposite direction and the lifting block moves downward, the baffle rotates away from the crucible under the relaxation of the pull rope, and the fixed clamping block separates from the outer wall of the crucible, making it easy to remove the product from the crucible. The method of clamping or releasing the crucible by rotating the baffle through the cooperation of the drive screw, the lifting block and the pull rope is simple in structure and easy to operate, and can quickly position and fix the crucible.

[0011] Optionally, a torsion spring is provided at the end of the rotating shaft, with one end of the torsion spring fixed to the rotating shaft and the other end fixed to the bearing platform.

[0012] By adopting the above technical solution, when the lifting block moves upward, the torsion spring stores elastic potential energy; when the lifting block moves downward, the torsion spring rotates to the horizontal under the action of torsional force, so that the rotating shaft drives the baffle to rotate away from the crucible, thereby separating the fixed clamp from the outer wall of the crucible, making it easier to release the crucible and take out the product inside the crucible; the torsion spring makes the crucible release operation more convenient.

[0013] Optionally, the driving component further includes a worm gear fixedly sleeved on the outside of the driving screw, a worm rotatably connected to the frame and meshing with the worm gear, and a crank fixed to one end of the worm.

[0014] By adopting the above technical solution, turning the crank can drive the worm to rotate. Since the worm meshes with the worm wheel, the rotation of the worm can drive the drive screw to rotate. The cooperation between the worm wheel and worm can achieve precise rotation of the drive screw, making the control of the drive screw more accurate and facilitating precise adjustment of the rotation angle of the drive screw according to actual needs. At the same time, the worm wheel and worm have self-locking properties, which can lock the position after the drive screw rotates to the appropriate position, preventing the drive screw from rotating accidentally due to vibration or other reasons. Moreover, the driving method is simple and convenient to operate. The rotation of the drive screw can be easily controlled by the crank, and then the drive screw drives the movement of related components to achieve operations such as clamping or loosening the crucible, improving the convenience and reliability of the device operation.

[0015] Optionally, a lifting screw is fixed to the top of the drive screw, and the thread direction of the lifting screw is opposite to that of the drive screw; The lifting screw is threaded with a movable sleeve on its outer side, and the outer wall of the movable sleeve is provided with an adjusting thread; A movable seat is slidably connected within the sliding groove, and the movable seat is fixed to the movable sleeve; an upper locking nut and a lower locking nut are threadedly connected to the outer wall of the movable sleeve. A bracket is slidably connected to the movable base along its vertical axis. One end of the bracket is sleeved onto the outside of the movable sleeve and located between the upper locking nut and the lower locking nut. The other end of the bracket is fixed to the dust cover.

[0016] By adopting the above technical solution, when the drive screw rotates, the moving sleeve moves up and down along the lifting screw because the threads of the lifting screw and the drive screw are opposite and fixed. The moving sleeve is fixed to the moving seat, so the moving seat slides synchronously in the sliding groove. When the baffle flips and drives the fixed clamp to fix the outer wall of the crucible, the drive screw rotates, the moving sleeve moves, and the support moves down synchronously with the dust cover to seal the top opening of the crucible, preventing graphite material from spilling out during the compaction process. Conversely, when the baffle flips and loosens the outer wall of the crucible, the drive screw rotates in the opposite direction, and the dust cover moves up synchronously to open the top opening of the crucible. Moreover, the upper and lower locking nuts are threaded to the outer wall of the moving sleeve. By adjusting their positions on the moving sleeve, the vertical position of the support can be changed. When using crucibles of different heights and capacities, the positions of the support and the dust cover can be flexibly adjusted by adjusting the positions of the upper and lower locking nuts, realizing the synchronous operation of sealing and opening the top opening during the compaction process of crucibles of different specifications. This improves the versatility and applicability of the device and ensures that the compaction process is efficient and environmentally friendly.

[0017] Optionally, the top of the fixing block near the crucible is arranged in an arc shape that fits against the outer wall of the crucible.

[0018] By adopting the above technical solution, when the clamping and positioning mechanism fixes the crucible, the arc-shaped surface can fit tightly against the outer wall of the crucible, increasing the contact area between the fixing block and the crucible, thus fixing the crucible more firmly. Moreover, the fitting arc-shaped surface can evenly distribute the pressure applied to the crucible, avoiding excessive local pressure that could damage the crucible.

[0019] Optionally, a retaining strip is fixed to the side of the baffle near the fixing block, and a retaining groove is provided on one side of the fixing block, into which the retaining strip can be inserted.

[0020] By adopting the above technical solution, when installing the fixing block, simply align the slot on one side of the fixing block with the clip fixed on the baffle and insert it to complete the installation of the fixing block on the baffle. This connection method is simple to operate and can quickly realize the installation of the fixing block. When the fixing block is worn or damaged after long-term use, simply pull the clip out of the slot to remove the fixing block, which is convenient for replacement or repair.

[0021] Optionally, the elastic shock absorption assembly includes multiple rubber springs, which are evenly distributed and connected between the support platform and the frame, and the bottom of the frame is also provided with multiple shock-absorbing pads.

[0022] By adopting the above technical solution, the rubber spring can buffer the impact of vibration on the frame when the vibration generating mechanism generates high-frequency vibration to compact the material in the crucible, reduce the noise generated by the vibration transmitted to the frame, and protect the frame structure from excessive vibration. At the same time, multiple shock-absorbing pads installed at the bottom of the frame further isolate the vibration transmitted to the ground.

[0023] Optionally, the vibration generating mechanism includes a vibration motor fixed to the bottom of the crucible.

[0024] By adopting the above technical solution, the high-frequency vibration generated by the vibration motor can be used to efficiently compact the material in the crucible, which can significantly improve the loose packing density of graphite and increase the filling capacity of a single crucible.

[0025] In summary, this application includes at least one of the following beneficial technical effects: High-frequency vibration is generated by a vibrating motor fixed to the bottom of the crucible to efficiently compact the material inside the crucible. The high-frequency vibration causes the graphite particles inside the crucible to rearrange and fill the gaps between the particles, which significantly increases the loose density of graphite and thus increases the filling capacity of a single crucible. The elastic damping components and damping pads can absorb the vibration energy generated by the vibration generating mechanism, reduce the transmission of vibration to the frame and the ground, play a role in vibration reduction and noise reduction, and protect the equipment and the ground foundation, thus extending the service life of the equipment. When it is necessary to fix the crucible, the drive unit drives the baffle to move closer to the crucible, and the fixing block will press against the outer wall of the crucible, thereby firmly fixing the crucible on the support platform and preventing it from shifting or tipping over during the compaction process, thus improving the safety and stability of the operation. When the compaction operation is completed and it is necessary to remove the product from the crucible, the drive unit drives the baffle to move away from the crucible, and the fixing block separates from the outer wall of the crucible, making it easy to remove the crucible. A drive system enables synchronous linkage between crucible clamping and dust cover lifting. The operator only needs to turn the handle to automatically lower the dust cover to seal while clamping the crucible, which simplifies the operation and improves work efficiency. The lifting bracket of the dust cover is adjusted in position by upper and lower locking nuts, so that the starting height of the dust cover can be flexibly adjusted according to crucibles of different specifications. With the detachable fixing block, the device can adapt to crucibles of various sizes and shapes, improving the versatility and applicability of the crucible compaction device. Using a worm gear mechanism as the transmission source not only enables precise fine-tuning of the clamping force, preventing damage to the crucible, but also utilizes its inherent self-locking characteristics to ensure that the clamping force and the sealing state of the dust cover remain stable during the compaction process, improving the reliability and safety of the device. Furthermore, by setting a torsion spring auxiliary baffle for automatic reset, when the drive screw reverses to release the crucible, the torsion spring can quickly drive the baffle to spring outward, realizing the rapid and automatic release of the fixed clamping block, which facilitates the removal of the crucible after compaction.

[0028] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0029] This application discloses a crucible compaction device. (Refer to...) Figure 1The crucible compaction device includes a frame 1, with a support platform 2 mounted on top of the frame 1. The support platform 2 is used to horizontally place the crucible 3 to be compacted. To achieve efficient compaction, a vibration generating mechanism 4 is installed below the support platform 2. The vibration generating mechanism 4 is a vibration motor fixed to the bottom of the support platform 2. When the vibration motor is started, the high-frequency excitation force is directly transmitted through the support platform 2 to the bottom of the crucible 3, causing the graphite particles in the crucible 3 to squeeze and rub against each other, filling the gaps, increasing the loose packing density of the graphite, and increasing the filling capacity of a single crucible 3.

[0030] Reference Figure 1 To protect the equipment structure and improve the working environment, an elastic damping component 5 is installed between the support platform 2 and the frame 1. The elastic damping component 5 includes several rubber springs 51 evenly distributed between the connection points of the support platform 2 and the frame 1. The rubber springs 51 absorb and dissipate most of the vibration energy, preventing vibration from being directly and rigidly transmitted to the frame 1, significantly reducing operating noise and mitigating structural fatigue. To further isolate vibration transmission to the ground, damping pads 52 are also installed at the four support legs at the bottom of the frame 1, forming a double vibration isolation system.

[0031] Reference Figure 1 and Figure 2 To ensure the stability of the crucible 3 during the compaction process and prevent it from shifting horizontally or tipping over under high-frequency vibration, a clamping and positioning mechanism 6 is also provided on the frame 1. The clamping and positioning mechanism 6 includes a rotating shaft 61 rotatably connected to the support platform 2. A baffle 62 is fixed along the length of the rotating shaft 61, and a fixing block 63 is detachably connected to the side of the baffle 62 near the crucible 3. Specifically, referring to the figure, a dovetail-shaped retaining strip 621 is fixed on the baffle 62, and a matching retaining groove 631 is opened on one side of the fixing block 63. During installation, simply align the retaining groove 631 with the retaining strip 621 and insert it to complete the fixation. It is easy to install and remove, and it is convenient to replace the fixing block 63 with different curvatures or materials according to the different diameters of the crucible 3. To improve the stability of the clamping and protect the crucible 3, the top of the fixing block 63 near the crucible 3 is designed as an arc surface 632. The curvature of the arc surface 632 fits the curvature of the outer wall of the crucible 3, increasing the contact area, making the clamping force evenly distributed, and avoiding stress concentration that could damage the crucible 3.

[0032] Reference Figures 2-4A drive component 65 is provided between the baffle 62 and the frame 1 to drive its rotation. The drive component 65 includes a drive screw 651 vertically rotatably connected to the frame 1. A sliding groove 11 is formed vertically on the side wall of the frame 1, and a lifting block 652 is slidably embedded in the sliding groove 11. The lifting block 652 forms a threaded transmission with the drive screw 651 through an internal threaded hole. A high-strength pull rope 653 is fixedly connected to each of the two sides of the baffle 62, and the other end of the pull rope 653 is fixed to the lifting block 652. At the same time, a torsion spring 64 is installed at the end of the rotating shaft 61, and the two ends of the torsion spring 64 are fixed to the rotating shaft 61 and the bearing platform 2, respectively.

[0033] Reference Figure 4 and Figure 5 To achieve more effortless and precise control, the drive component 65 is also equipped with a speed reduction and torque increase structure and a self-locking mechanism. Specifically, a worm gear 654 is fixedly sleeved on the outer side of the lower end of the drive screw 651, and a worm 655 that meshes with the worm gear 654 is rotatably connected to the frame 1. One end of the worm 655 extends out of the frame 1 and is fixed with a crank handle 656.

[0034] When the operator turns the crank handle 656, the worm gear 655 drives the worm wheel 654 and the drive screw 651 to rotate synchronously. When the drive screw 651 rotates forward, the lifting block 652 slides upward along the sliding groove 11, pulling the baffle 62 around the rotation axis 61 towards the crucible 3 via the pull rope 653. During this process, the torsion spring 64 is twisted and stores energy. The baffle 62 drives the arc-shaped surface 632 of the fixed clamping block 63 to press tightly against the outer wall of the crucible 3, achieving a stable clamping. Due to the self-locking property of the worm wheel 654 and worm gear 655 mechanism, the clamping force remains unchanged even if the crank handle 656 is released. When the compaction is complete and the crucible 3 needs to be released, the crank handle 656 is turned in the opposite direction, causing the drive screw 651 to reverse, the lifting block 652 to move downward, and the pull rope 653 to loosen. At this time, the previously stored torsion spring 64 releases its elastic potential energy, driving the rotating shaft 61 to rotate automatically in the opposite direction, causing the baffle 62 and the fixed clamp 63 to quickly spring outward and separate from the crucible 3, making it easier to remove the crucible 3.

[0035] Reference Figure 4 and Figure 6The frame 1 is equipped with a dust cover 7 to seal the top opening of the crucible 3 during the compaction process to prevent graphite material from overflowing. The dust cover 7 is raised and lowered above the crucible 3. A lifting screw 66 is coaxially fixed to the top of the drive screw 651, and the thread direction of the lifting screw 66 is opposite to that of the drive screw 651. A movable sleeve 661 is threaded on the outer side of the lifting screw 66, and the outer wall of the movable sleeve 661 has an adjusting thread. A movable seat 662 is fixedly connected to the outside of the movable sleeve 661, and the movable seat 662 is slidably connected in the sliding groove 11. An L-shaped bracket 665 is slidably connected to the movable seat 662 vertically, one end of which is slidably fitted onto the movable sleeve 661, and the other end is fixed to the top of the dust cover 7. Above and below the fitting of the bracket 665, the adjusting thread of the movable sleeve 661 is screwed with an upper locking nut 663 and a lower locking nut 664, respectively. By screwing these two nuts, the bracket 665 can be fixed at any height position of the movable sleeve 661.

[0036] When the drive screw 651 rotates to clamp the crucible 3, the moving sleeve 661 is driven to move downwards because the lifting screw 66 rotates in the opposite direction. The moving sleeve 661 then drives the bracket 665 and dust cover 7 to move downwards synchronously via the upper locking nut 663 and lower locking nut 664. At the moment the clamping action is completed, the dust cover 7 is precisely and tightly fastened to the top opening of the crucible 3, forming a closed space. When the drive screw 651 reverses to release the crucible 3, the moving sleeve 661 moves upwards, simultaneously lifting the dust cover 7 to make room for removing the crucible 3. When handling crucibles 3 of different heights, simply loosen the lower locking nut 664, slide the bracket 665 and dust cover 7 along the moving sleeve 661 to a position matching the height of the crucible 3, and then tighten the upper locking nut 663 and lower locking nut 664 to lock them in place. This allows for flexible adjustment.

[0037] The implementation principle of the crucible 3 compaction device in this application embodiment is as follows: Before operation, select a suitable fixing clamp 63 according to the size of the crucible 3 and insert it into the baffle 62. Adjust the upper locking nut 663 and the lower locking nut 664 to set the dust cover 7 to a suitable height. Place the crucible 3 filled with material on the support platform 2. Rotate the crank handle 656, and the power is transmitted to the drive screw 651 after being reduced and increased in torque by the worm gear 655 and worm wheel 654. The rotation of the drive screw 651 causes the lifting block 652 to move upward and pull the pull rope 653, forcing the baffle 62 to overcome the elastic force of the torsion spring 64 and flip towards the crucible 3 until the arc surface 632 of the fixing clamp 63 firmly clamps the crucible 3. At the same time, the lifting screw 66, which rotates in the opposite direction, drives the moving sleeve 661 and the dust cover 7 to move downward synchronously. At the moment the crucible 3 is clamped, the dust cover 7 just closes the top opening of the crucible 3. At this point, the vibration motor is activated, and high-frequency vibration is transmitted to the crucible 3 through the support platform 2, efficiently compacting the graphite material inside. The downward energy transmitted during vibration is absorbed by the rubber spring 51 and the shock-absorbing pads 52, ensuring smooth operation and low noise throughout the equipment. After compaction, the vibration motor is stopped, the crank handle 656 is rotated in the opposite direction, driving the screw 651 to reverse, the lifting block 652 moves downward, and the baffle 62 automatically springs open under the elastic force of the torsion spring 64, releasing the crucible 3. Simultaneously, the dust cover 7 is raised. The compacted crucible 3 can then be safely and conveniently removed. The entire operation involves a single, coordinated step for clamping and sealing, making it simple, convenient, safe, and environmentally friendly. It efficiently, environmentally friendly, and stably compacts the graphite material inside the crucible 3, and is applicable to crucibles of different specifications, demonstrating good versatility and applicability, significantly improving production efficiency and product quality.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
