Abstract
Description
Technical Field
[0001] This application relates to the technical field of graphite purification, and in particular to a highly efficient spherical graphite purification reaction vessel. Background Technology
[0002] The prerequisite for deep processing of graphite is purification. Graphite purification is a complex atomization process that requires mixing graphite powder, water, and acid in a certain proportion, stirring and reacting in a reaction vessel to dissolve impurities in the graphite and purify it.
[0003] For related technology, please refer to Chinese Patent No. CN217093474U, which discloses a reaction vessel with good reaction effect, including a tank body, a horizontally arranged coil at the top of the tank body, several liquid inlet holes at the bottom of the coil, a feed pipe passing through the top of the tank body, the feed pipe being fixedly connected and communicating with the coil, a stirring device being provided in the tank body, a solid feed inlet being provided at the top of the tank body, and a sieve plate being provided below the solid feed inlet.
[0004] Regarding the aforementioned technologies, although the mixing and dispersion of materials in the reactor can be improved by using coils and fan discs, when water and acid wash the graphite powder on the screen disc, a viscous liquid is formed, which easily adheres to the screen disc and is difficult to clean later. The material on the screen disc does not fall completely due to gravity. Utility Model Content
[0005] To improve the material falling effect on the sieve plate and reduce the residual material on the sieve plate, this application provides a high-efficiency spherical graphite purification reaction vessel.
[0006] This application provides a high-efficiency spherical graphite purification reaction vessel, employing the following technical solution:
[0007] A high-efficiency spherical graphite purification reaction vessel includes a vessel body, a vertically mounted stirring shaft inside the vessel body, a horizontally mounted coil at the top of the vessel body, several liquid inlet holes at the bottom of the coil, a feed pipe passing through the top of the vessel body and fixedly connected to and communicating with the coil, a feed inlet at the top of the vessel body, a sieve disc below the feed inlet, the sieve disc being a circular disc structure, the stirring shaft passing through and connected to the sieve disc, several sieve holes on the sieve disc, an annular groove with a height difference on the surface of the stirring shaft, an annular opening in the center of the sieve disc, a sliding block fixedly connected to the inner wall of the annular opening of the sieve disc and cooperating with the annular groove, a limiting plate fixedly connected to the inner wall of the vessel body, a limiting groove on the limiting plate, and a limiting block located within the limiting groove fixedly connected to the outer wall of the sieve disc.
[0008] By adopting the above technical solution, during use, a reaction solution of water and acid is delivered into the tank through the top feed pipe. The reaction solution is evenly sprayed through the feed hole of the coil, and graphite powder is delivered into the tank through the feed port. The graphite powder falls evenly onto the sieve plate and into the tank through the sieve holes. While the reaction solution washes away the graphite powder remaining on the sieve plate, it also falls evenly into the tank through the sieve plate and reacts fully with the graphite powder. When the stirring shaft rotates, the sliding block slides along the annular groove. Due to the height difference of the annular groove, the sieve plate moves up and down during the rotation of the stirring shaft. The sieve plate is limited by the limiting groove and the limiting block to prevent the sieve plate from rotating with the stirring shaft. The up and down movement of the sieve plate shakes the material off the sieve plate, improving the material falling effect and reducing the residual material on the sieve plate.
[0009] Optionally, a striking rod is fixedly connected to the inner wall of the tank, and a striking block that cooperates with the sieve plate is fixedly connected to the end of the striking rod.
[0010] By adopting the above technical solution, when the screen plate moves upward, it is struck by the striking block when it reaches the highest point, causing the screen plate to vibrate slightly, which improves the material falling effect on the screen plate and reduces the residual material on the screen plate.
[0011] Optionally, the screen plate near the screen holes has a smooth transition from the plate surface to the screen holes, and the screen plate is inclined from the center of the screen plate to the periphery.
[0012] By adopting the above technical solution, when graphite powder falls onto the sieve plate, the inclined setting of the sieve plate allows the graphite powder to slide down along the inclined direction. During the sliding process, the powder is gradually sieved down, improving the degree of dispersion. During the sliding process, as the powder passes through the sieve holes, the plate surface smoothly transitions towards the sieve holes, achieving uniform dispersion and falling.
[0013] Optionally, the sieve plate is located below the coil, and the liquid inlet hole on the coil faces the sieve plate.
[0014] By adopting the above technical solution, the reaction liquid sprayed from the coil can wash away the graphite powder on the sieve plate after passing through the sieve plate, and achieve preliminary solid-liquid mixing, thereby improving the mixing effect.
[0015] Optionally, the stirring shaft is provided with stirring paddles at intervals, and the edges of the stirring paddles are fixedly connected with shearing teeth.
[0016] By adopting the above technical solution, the stirring paddle stirs the tank, accelerating the reaction speed. The shearing teeth on the edge of the stirring paddle can exert shearing force on the fluid, reducing the possibility of graphite powder agglomeration and improving the reaction effect.
[0017] Optionally, the top of the feed inlet is threadedly connected to a matching top cover.
[0018] By adopting the above technical solution, the top cover is used to cover the top of the feed inlet and seal the tank after feeding is completed, reducing the entry of impurities.
[0019] Optionally, a connecting rope is fixedly connected to the top of the top cover, and one end of the connecting rope away from the top cover is fixedly connected to the outer wall of the top of the tank.
[0020] By adopting the above technical solution, the connecting rope is used to connect the tank body to the top cover, thereby reducing the probability of the top cover being lost.
[0021] Optionally, a jacket is provided outside the tank body, and a baffle is provided inside the jacket.
[0022] By adopting the above technical solution, the jacket facilitates heating of the tank, and the baffle can improve the liquid flow within the jacket, enhance internal temperature uniformity, and thus improve the reaction effect.
[0023] Optionally, a fixing sleeve is fixedly connected to the outer wall of the tank, and several legs are fixedly connected to the bottom of the fixing sleeve.
[0024] By adopting the above technical solution, the tank body can be easily supported by the fixing sleeve and the support legs, which is beneficial to the stability of the tank body.
[0025] In summary, this application includes at least one of the following beneficial technical effects:
[0026] 1. When the stirring shaft rotates, the sliding block slides along the annular groove. Due to the height difference of the annular groove, the screen plate moves up and down during the rotation of the stirring shaft. The screen plate is limited by the limiting groove and the limiting block to prevent the screen plate from rotating with the stirring shaft. The up and down movement of the screen plate shakes the material off the screen plate, improves the material falling effect on the screen plate, and reduces the residual material on the screen plate.
[0027] 2. With the setting of the coil and sieve, the reaction liquid is evenly sprayed through the feed hole of the coil and graphite powder is conveyed into the tank through the feed port. The rotation of the stirring shaft drives the sieve to rotate, and the graphite powder falls evenly on the sieve and into the tank through the sieve holes. At the same time, the reaction liquid washes off the graphite powder remaining on the sieve and reacts evenly with the graphite powder in the tank through the sieve, which is beneficial to improving the reaction effect.
[0028] 3. When the screen plate moves upward, it is struck by the striking block when it reaches the highest point, causing the screen plate to vibrate slightly. This improves the material falling effect on the screen plate and reduces the residual material on the screen plate. Attached Figure Description

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.
[0034] This application discloses a high-efficiency spherical graphite purification reaction vessel.
[0035] Reference Figure 1 and Figure 2 A high-efficiency spherical graphite purification reaction vessel includes a vessel body 1, a drive motor 21 mounted on the top of the vessel body 1, a stirring shaft 2 vertically mounted inside the vessel body 1, the stirring shaft 2 being fixedly connected to the output shaft of the drive motor 21, stirring paddles 22 being installed at intervals on the stirring shaft 2, a feed pipe 11 passing through the top of the vessel body 1, a coil 3 horizontally mounted on the top of the vessel body 1, a plurality of liquid inlet holes 31 opening at the bottom of the coil 3, the feed pipe 11 being fixedly connected to and communicating with the coil 3, a feed inlet 12 opening at the top of the vessel body 1, and a discharge outlet 13 opening at the bottom of the vessel body 1. In use, a reaction solution of water and acid is fed into the vessel body 1 through the top feed pipe 11, the reaction solution is evenly sprayed through the feed holes of the coil 3, graphite powder is fed into the vessel body 1 through the feed inlet 12, the stirring shaft 2 rotates to stir the graphite powder and reaction solution in the vessel body 1, ensuring thorough mixing and reaction, and the product is discharged through the discharge outlet 13.
[0036] Reference Figure 1 and Figure 2 The top of the feed inlet 12 is threadedly connected to a matching top cover 121, which is used to cover the top of the feed inlet 12 and seal the tank 1 after feeding is completed, reducing the entry of impurities. A connecting rope 122 is fixedly connected to the top of the top cover 121. The end of the connecting rope 122 away from the top cover 121 is fixedly connected to the outer wall of the top of the tank 1 to reduce the probability of the top cover 121 being lost.
[0037] Reference Figure 1 and Figure 2The tank body 1 is provided with a jacket 14, and a baffle 141 is provided inside the jacket 14. The jacket 14 facilitates the heating of the tank body, and the baffle 141 can improve the liquid flow inside the jacket 14, improve the internal temperature uniformity, and thus improve the reaction effect.
[0038] Reference Figure 1 and Figure 2 A fixing sleeve 15 is fixedly connected to the outer wall of the tank body 1, and several support legs 16 are fixedly connected to the bottom of the fixing sleeve 15. The fixing sleeve 15 and the support legs 16 facilitate the support of the tank body, which is beneficial to the stability of the tank body.
[0039] Reference Figure 2 Inside the tank 1, a sieve plate 4 is installed below the coil 3. The liquid inlet 31 on the coil 3 faces the sieve plate 4. The sieve plate 4 has a circular structure, and the area near the sieve holes 41 of the sieve plate 4 smoothly transitions from the disc surface to the sieve holes 41. The stirring shaft 2 passes through the sieve plate 4 and is connected to it. The sieve plate 4 is inclined from the end near the stirring shaft 2 to the end away from the stirring shaft 2. In use, graphite powder is fed into the tank 1 through the feed inlet 12. The rotation of the stirring shaft 2 drives the sieve plate 4 to rotate. When the graphite powder falls onto the sieve plate 4, it slides down through the sieve holes 41, achieving uniform dispersion as it falls. The reaction liquid sprayed from the coil 3 washes the graphite powder off the sieve plate 4, achieving preliminary solid-liquid mixing and improving the mixing effect. The reaction liquid falls evenly into the tank 1 through the sieve plate 4 and reacts fully with the graphite powder, which is beneficial for improving the reaction effect.
[0040] Reference Figure 2 and Figure 3 An annular groove 23 with a height difference is provided on the surface of the stirring shaft 2, and an annular opening 42 is provided in the middle of the sieve plate 4. A sliding block 43 that cooperates with the annular groove 23 is fixedly connected to the inner wall of the annular opening 42 of the sieve plate 4.
[0041] Reference Figure 2 A limiting plate 6 is fixedly connected to the inner wall of the tank body 1. A limiting groove 61 is opened on the limiting plate 6. A limiting block 44 located in the limiting groove 61 is fixedly connected to the outer wall of the screen plate 4.
[0042] Reference Figure 2 and Figure 3 When the stirring shaft 2 rotates, the sliding block 43 slides along the annular groove 23. Due to the height difference of the annular groove 23, the screen plate 4 moves up and down during the rotation of the stirring shaft 2. The screen plate 4 is limited by the limiting groove 61 and the limiting block 44 to prevent the screen plate 4 from rotating with the stirring shaft 2. The up and down movement of the screen plate 4 shakes the material off the screen plate 4, improves the material falling effect on the screen plate 4, and reduces the residual material on the screen plate 4.
[0043] Reference Figure 2 A knocking rod 5 is fixedly connected to the inner wall of the tank body 1. A knocking block 51 that cooperates with the screen plate 4 is fixedly connected to the end of the knocking rod 5. When the screen plate 4 moves upward to the highest point, it will be knocked by the knocking block 51, causing the screen plate 4 to vibrate slightly, which improves the material falling effect on the screen plate 4 and reduces the residual material on the screen plate 4.
[0044] Reference Figure 2 The edge of the stirring paddle 22 is fixedly connected with shearing teeth 221. The shearing teeth 221 on the edge of the stirring paddle 22 can exert shearing force on the fluid, reduce the possibility of graphite powder agglomeration, and improve the reaction effect.
[0045] The implementation principle of a high-efficiency spherical graphite purification reaction vessel in this application embodiment is as follows: During use, a reaction solution of water and acid is supplied to the vessel 1 through the top feed pipe 11. The reaction solution is evenly sprayed through the feed hole of the coil 3, and graphite powder is supplied to the vessel 1 through the feed port 12. The graphite powder falls evenly onto the sieve plate 4 and into the vessel 1 through the sieve holes 41. While the reaction solution washes away the graphite powder remaining on the sieve plate 4, it also falls evenly into the vessel 1 through the sieve plate 4 and reacts fully with the graphite powder. When stirred... When shaft 2 rotates, sliding block 43 slides along annular groove 23. Due to the height difference of annular groove 23, screen plate 4 moves up and down during the rotation of stirring shaft 2. Screen plate 4 is limited by limiting groove 61 and limiting block 44 to prevent screen plate 4 from rotating with stirring shaft 2. The up and down movement of screen plate 4 shakes the material off screen plate 4. When screen plate 4 moves upward, it is struck by striking block 51 when it reaches the highest point, causing screen plate 4 to vibrate slightly, which improves the material falling effect on screen plate 4 and reduces residual material on screen plate 4.
[0046] 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.
