Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite finishing technology, and in particular to a special expandable graphite finishing device. Background Technology
[0002] Special expandable graphite is a high-performance graphite derivative prepared from ordinary expandable graphite through specific modification processes. Its core characteristics are the retention of the basic properties of expandable graphite, such as rapid volume expansion at high temperatures, high temperature resistance, corrosion resistance, and excellent sealing performance, while achieving targeted optimization in terms of expansion rate, expansion ratio stability, mechanical strength, and compatibility with suitable media. It is applied in fields such as sealing materials, fire-retardant materials, environmentally friendly adsorbent materials, and thermally and electrically conductive composite materials. Special expandable graphite finishing equipment is a specialized finishing device designed specifically to adapt to the characteristics of special expandable graphite materials. Unlike ordinary powder finishing equipment, it needs to address the layered structure, easy expansion characteristics, and stability of modified components of special expandable graphite, achieving targeted treatments such as particle size classification, lamellar regularization, impurity screening, moisture control, and volume uniformity. The core objective is to solve problems that easily occur during the preparation of special expandable graphite, such as uneven particle size distribution, lamellar breakage, modified component shedding, and poor volume consistency, ensuring the stability and reliability of key indicators such as expansion performance, sealing performance, and flame retardant performance in subsequent applications.
[0003] Currently, most commercially available special expandable graphite sorting devices employ multiple layers of fixed screens with different apertures. After the special expandable graphite is fed from the top of the device, it falls under its own weight and passes through the screens. The screens with different apertures respectively trap graphite particles of corresponding volumes, thus completing the grading. However, in actual use, this method suffers from the lack of active vibration function of the fixed screens. When graphite particles with a volume close to the screen aperture fall, the graphite particles that should have been trapped pass through the screen, ultimately affecting product performance due to poor consistency in the volume of the graded graphite. Utility Model Content
[0004] To overcome the above deficiencies, this utility model provides a special expandable graphite finishing device, which aims to improve the problem of poor volume consistency of graphite after grading, which affects product performance.

[0017] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Reference Figure 1 and Figure 2This utility model provides an embodiment of a special expandable graphite sorting device, including a fixed bracket 1, a motor 2 fixedly connected to the outer wall of the fixed bracket 1, a rotating column 3 fixedly installed at the output end of the motor 2, a turntable bracket 4 fixedly connected to the outer wall of the rotating column 3, a rotating bracket 5 fixedly connected to the outer wall of the turntable bracket 4, a rotating bracket 6 rotatably connected to the outer wall of the rotating bracket 5, a rotating bracket 7 rotatably connected to the outer wall of the rotating bracket 6, a fixed column 8 rotatably connected to the outer wall of the rotating bracket 7, and a sieving assembly provided on the outer wall of the fixed column 8 for sieving the expandable graphite.
[0019] Specifically, the motor 2 on the outer wall of the fixed bracket 1 drives the rotating column 3 to rotate. The fixed bracket 1 supports the rotating column 3, which in turn drives the turntable bracket 4 to rotate. The inner wall of the rotating bracket 5 is rotatably connected to the column on the outer wall of the turntable bracket 4. The rotating bracket 5 then rotates in a circular motion around the axis of the turntable bracket 4, causing the rotating bracket 6 to reciprocate on the column inside the fixed bracket 1. At the same time, it pulls the rotating bracket 7 and the fixed column 8 to reciprocate. Since the outer wall of the fixed column 8 is equipped with a screening component, the screening component moves repeatedly, generating vibration force. This prevents the expandable graphite from adhering to the inner wall when it is applied to the screening component, thus improving efficiency.
[0020] Reference Figure 1 and Figure 3 The screening assembly includes a limiting bracket 1 9, the outer wall of which is set on the outer wall of the fixed column 8, a screening screen 10 fixedly connected to the inner wall of the limiting bracket 1 9, a slider 11 fixedly connected to the outer wall of the limiting bracket 1 9, a limiting bracket 2 12 slidably connected to the inner wall of the slider 11, a motor 2 13 fixedly connected to the outer wall of the limiting bracket 2 12, a rotating column 2 14 fixedly set at the output end of the motor 2 13, and a baffle 15 fixedly connected to the outer wall of the rotating column 2 14. Specifically, as the fixed column 8 reciprocates, it pulls the limiting bracket 9 and the sieve 10 to reciprocate, thereby generating vibration. When expandable graphite falls onto the sieve 10, because the sieve 10 is tilted, excessively expanded graphite falls into the container set on the outer wall of the limiting bracket 12, while small-volume graphite falls into the inner wall of the limiting bracket 12. This avoids the graphite's performance being affected by the uneven volume of graphite. The slider 11 restricts the sieve 10 to always be aligned with the limiting bracket 12 below and not to fall off from the top of the limiting bracket 12, ensuring that small-volume graphite always falls into the limiting bracket 12. When the motor 13 starts, it drives the rotating column 14, causing the expandable graphite to fall into the gap between the baffles 15. Through the rotation of the rotating column 14, it gradually and evenly falls out from the outlet set on the limiting bracket 12, achieving the effect of improving performance and saving costs.
[0021] Reference Figure 2 The outer wall of rotating column 3 is rotatably connected to the inside of fixed bracket 1, and the outer wall of rotating bracket 2 6 is rotatably connected to the outer wall of fixed bracket 1. Specifically, by supporting the rotating column 3 with the fixed bracket 1, it is ensured that the rotating column 3 always rotates and its position does not change when driven by the motor 2. At the same time, the fixed bracket 1 restricts the rotating bracket 6 so that the rotating bracket 6 will not fall off the inside of the fixed bracket 1 when it is reciprocating.
[0022] Reference Figure 1 and Figure 2 The outer wall of the fixed column 8 is slidably connected to the inside of the fixed bracket 1, and the outer wall of the fixed bracket 1 is fixedly connected to the outer wall of the limiting bracket 12. Specifically, the fixed bracket 1 supports the fixed column 8, so that the fixed column 8 always pulls the limiting bracket 9 and the screen 10 to reciprocate when it is reciprocating. At the same time, the fixed bracket 1 and the limiting bracket 2 are fixedly connected, so that the fixed bracket 2 16 supports and fixes the fixed bracket 1 and the limiting bracket 2 12, preventing the components of the device from displacing when the device vibrates.
[0023] Reference Figure 1 and Figure 3 The outer wall of the rotating column 14 is rotatably connected to the inside of the limiting bracket 12, and the outer wall of the baffle 15 is attached to the inner wall of the limiting bracket 12. Specifically, the rotating column 14 is supported by the limiting bracket 2 12, so that the position of the rotating column 14 does not change when it is driven to rotate by the motor 2 13. At the same time, when the baffle 15 is rotated by the rotating column 14, it will not rub against the limiting bracket 2 12, and the graphite in the gap of the baffle 15 will not leak into the interior of the limiting bracket 2 12.
[0024] Reference Figure 1 and Figure 4 Fixed bracket 11 has a fixed bracket 2 16 fixedly connected to its outer wall. Fixed bracket 2 16 has a threaded rod 17 rotatably connected inside. Threaded rod 17 has a crank handle 18 fixedly connected to its outer wall. Threaded rod 17 has a sliding bracket 19 threadedly connected to its outer wall. Sliding bracket 20 has a fixedly connected sliding bracket 19 to its outer wall. Fixed bracket 3 21 has a sliding connection to the outer wall of sliding bracket 20. Fixed bracket 2 16 has its outer wall fixedly connected to the outer wall of limiting bracket 2 12. Fixed bracket 3 21 has its outer wall fixedly connected to the outer wall of fixed bracket 2 16. Sliding bracket 1 19 has its outer wall fitted to the outer wall of fixed bracket 2 16. Fixed bracket 3 21 has its outer wall fitted to the outer wall of limiting bracket 2 12. Specifically, rotating the crank handle 18 on the outer wall of the fixed bracket 1 causes the threaded rod 17 to rotate, causing the sliding bracket 19 on the outer wall of the threaded rod 17 to slide. This, in turn, causes the sliding bracket 20 to slide on the inner wall of the fixed bracket 3 21. The sliding bracket 20 has a hollow graphite outlet at one end and a solid plate at the other. When the hollow outlet aligns with the outlet of the limiting bracket 2 12, expandable graphite falls out, allowing the operator to collect it. When a certain amount is collected, rotating the crank handle 18 in the opposite direction aligns the solid plate portion of the sliding bracket 2 20 with the outlet of the limiting bracket 2 12, stopping the graphite from falling. This facilitates the collection and organization of the required amount of graphite, thereby achieving... To improve accuracy, the fixed bracket 2 16 and the limiting bracket 2 12 are fixedly connected, making the device more stable during use. At the same time, the fixed bracket 2 16 and the fixed bracket 3 21 are fixedly connected, making the sliding bracket 2 20 more stable when sliding on the inner wall of the fixed bracket 3 21. The fixed bracket 2 16 restricts the sliding bracket 1 19 to prevent it from falling off the outer wall of the threaded rod 17 when sliding. The outer wall of the fixed bracket 3 21 is always in contact with the outer wall of the limiting bracket 2 12, so that the graphite will not fall off due to the gap between the sliding bracket 2 20 and the limiting bracket 2 12 when falling. This achieves the effect of reducing costs and improving the stability of the device.
[0025] Working principle: When it is necessary to process expandable graphite, the expandable graphite is poured onto the sieve 10. First, the motor 2 is started to drive the rotating column 3 to rotate inside the fixed bracket 1, which in turn causes the turntable bracket 4 to rotate. This causes the rotating bracket 5 to rotate around the axis of the turntable bracket 4, causing one end of the rotating bracket 6 to reciprocate around the column set on the inner wall of the fixed bracket 1. This drives the rotating bracket 7 and the fixed column 8 to move back and forth, while simultaneously pulling the limiting bracket 9 and the slider 11 on the outer wall of the limiting bracket 12. The slides back and forth on the track, causing the sieve 10 to vibrate. This allows expandable graphite to pass through the sieve 10 and enter the inner wall of the limiting bracket 2 12. The sieve 10 and the limiting bracket 1 9 are inclined, so that excessively expanded graphite cannot pass through the sieve 10 and slide out from the outlet of the limiting bracket 1 9. Instead, it falls into the receiving component on the outer wall of the limiting bracket 2 12 for secondary processing. This allows for the grading of expandable graphite and avoids the impact of inconsistent graphite volume on graphite performance during use, thereby improving performance and saving costs. After the expandable graphite is sieved, the rotating column 14 is driven to rotate by the starting motor 13. This causes the baffle 15 on the outer wall of the rotating column 14 to rotate around the axis of the rotating column 14, which can pour the sieved graphite downwards at a uniform speed and amount. At the same time, turning the crank handle 18 drives the threaded rod 17 to rotate inside the fixed bracket 16, which in turn causes the sliding bracket 19 to slide on the outer wall of the threaded rod 17. This, in turn, pushes the sliding bracket 20 to slide on the inner wall of the fixed bracket 21. One end of the second support 20 is hollow and the other end is solid. When the hollow part of the sliding support 20 is aligned with the outlet set by the limiting support 2 12 during the sliding process, the operator uses a container to collect the expandable graphite. When a certain amount of expandable graphite is collected, the operator turns the crank handle 18 in the opposite direction to align the solid part of the sliding support 20 with the outlet set by the limiting support 2 12, thereby stopping the graphite from falling. This allows for easy sorting according to the required amount of expandable graphite to be collected, thus improving the accuracy of graphite collection. In other words, when this device is used, it can not only classify expandable graphite and ensure that the volume of the screened graphite is uniform, thus improving its performance and saving costs, but also sort it according to the required amount of expanded graphite and improve the accuracy of graphite collection.

Although the present utility model 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.
