Description

Technical Field

[0001] The utility model belongs to the technical field of silicon carbon preparation, and in particular relates to a powder-liquid mixing device for silicon carbon preparation. Background Art

[0002] Silicon-carbon composites are composite materials that combine the advantages of silicon and carbon materials. Their role in batteries is mainly reflected in improving the energy density and cycle stability of batteries. When preparing silicon-carbon composites, high temperatures are usually used to cause silicon and carbon to react and generate a large amount of composite oxides. Since starch is an organic high-molecular carbohydrate with high purity, it can avoid impurities and ensure the consistency of the hard carbon structure. Therefore, when preparing the carbon raw material, starch can be added to the catalytic system solution, so that the carbon raw material in the starch can be extracted.

[0003] After the starch suspension is added to the catalytic system solution and the two are allowed to fully react, the black carbon powder extracted from the starch will be deposited at the bottom of the reactor. Due to the obstruction of the reactor, when taking out the carbon powder at the bottom of the reactor, the operator needs to continuously dig out the carbon powder at the bottom of the reactor, which makes it inconvenient to collect the carbon powder.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0030] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0031] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0032] See also Figures 1-8 As shown, the utility model is a powder-liquid mixing device for silicon-carbon preparation, comprising a reaction cylinder 1, a support roller 2 is arranged inside the reaction cylinder 1, a collecting component 3 is arranged on the outer surface of the support roller 2, a stirring component 4 is arranged on the top of the collecting component 3, a shielding component 5 is arranged on the top of the reaction cylinder 1, the shielding component 5 is dynamically connected to the rotating end of the support roller 2, a lifting component 6 is arranged on the top of the shielding component 5, and a driving component 7 is arranged on the bottom of the reaction cylinder 1, and the driving component 7 is dynamically connected to the support roller 2.

[0033] The driving assembly 7 is used to drive the supporting roller 2 so that the supporting roller 2 drives the collecting assembly 3 and the stirring assembly 4 to rotate inside the reaction cylinder 1. The shielding assembly 5 is used to shield the reaction cylinder 1. The lifting assembly 6 is used to extract the collecting assembly 3 upward so that the supernatant is discharged from the inside of the reaction cylinder 1. The stirring assembly 4 is used to lift the collecting assembly 3 out of the inside of the reaction cylinder 1.

[0034] The catalytic solution and starch suspension are put into the interior of the reaction cylinder 1. Since a heating plate is provided inside the barrel of the reaction cylinder 1, the reaction cylinder 1 can heat the catalytic solution and the starch suspension. At the same time, the driving component 7 drives the collecting component 3 and the stirring component 4 through the support roller 2 to rotate inside the reaction cylinder 1 and stir the catalytic solution and the starch suspension. When the two are fully reacted, the supernatant is discharged, and the collecting component 3 filters the carbon powder. Then the shielding component 5 is opened, and the collecting component 3 is taken out from the interior of the reaction cylinder 1 through the stirring component 4, and the carbon powder inside the collecting component 3 is poured out outside the reaction cylinder 1.

[0035] By setting up the collecting component 3, the carbon powder can be directly precipitated inside the collecting component 3 after the reaction of the catalytic solution and the starch suspension is completed. When the supernatant is discharged, the carbon powder will not be discharged together with the supernatant due to the obstruction of the collecting component 3. At the same time, the collecting component 3 can be lifted out of the interior of the reaction cylinder 1 through the stirring component 4 and the collected carbon powder can be poured out outside the reaction cylinder 1. The above-mentioned arrangement makes it more convenient to collect the carbon powder inside the reaction cylinder 1.

[0036] In one embodiment, for the above-mentioned collecting component 3, the collecting component 3 includes a conical filter box 301, the conical filter box 301 is fitted together with the inner wall of the reaction cylinder 1, the outer surface of the support roller 2 is provided with a positioning groove 302, and the interior of the positioning groove 302 is movably connected with a positioning bar 303, the positioning bar 303 is fixedly connected to the conical filter box 301, the bottom of the support roller 2 is fixedly connected with an L-shaped support rod 304, and the bottom of the conical filter box 301 is fixedly connected with a sleeve 305 corresponding to the L-shaped support rod 304.

[0037] The positioning strip 303 on the back of the conical filter box 301 is directly sleeved on the inside of the positioning groove 302, so that the conical filter box 301 can be moved to the inside of the reaction cylinder 1. At the same time, under the guidance of the positioning groove 302 and the positioning groove 302, the sleeve 305 at the bottom of the conical filter box 301 can be directly sleeved on the outer surface of the L-shaped support rod 304. The arrangement of the L-shaped support rod 304 and the sleeve 305 makes the connection between the conical filter box 301 and the support roller 2 relatively firm. At the same time, there are multiple conical filter boxes 301, which makes it more convenient to move multiple conical filter boxes 301 to the inside of the reaction cylinder 1. At the same time, the arrangement of the conical filter box 301 in contact with the bottom inner wall of the reaction cylinder 1 makes it possible for the carbon powder inside the starch suspension to fall directly into the interior of the conical filter box 301 when it is extracted, thereby ensuring the effect of the conical filter box 301 in collecting the carbon powder.

[0038] In one embodiment, for the above-mentioned stirring component 4, the stirring component 4 includes a stirring frame 401, the stirring frame 401 is fixedly connected to the conical filter box 301, a limiting groove 402 is opened on the top of the supporting roller 2, and the internal movable connection of the limiting groove 402 is provided with a limiting rod 403, and the limiting rod 403 is fixedly connected to the stirring frame 401.

[0039] When the conical filter box 301 is moved to the interior of the reaction cylinder 1, the corresponding stirring frame 401 will also move with it to the interior of the reaction cylinder 1. At the same time, the limiting rod 403 on the stirring frame 401 can be directly moved to the interior of the limiting groove 402. The setting of the limiting rod 403 and the limiting groove 402 makes the connection between the stirring frame 401 and the supporting roller 2 relatively firm, so that when the supporting roller 2 drives the conical filter box 301 and the stirring frame 401 to rotate, the overall stability of the stirring frame 401 can be guaranteed. The stirring frame 401 can not only stir the starch suspension and catalytic solution inside the reaction cylinder 1, but also can lift the conical filter box 301 out of the interior of the reaction cylinder 1 by pulling the stirring frame 401, so that it is relatively convenient to take the conical filter box 301 out of the interior of the reaction cylinder 1.

[0040] In one embodiment, for the above-mentioned shielding assembly 5, the shielding assembly 5 includes a shielding plate 501, the supporting roller 2 is rotatably connected to the shielding plate 501, the top of the shielding plate 501 is fixedly connected to the feeding pipe 502, the top of the shielding plate 501 is provided with a picking groove 503, the outer surface of the reaction cylinder 1 is rotatably connected to the flip cover 504, the flip cover 504 is movably connected to the picking groove 503, the outer surfaces of the shielding plate 501 and the flip cover 504 are provided with T-slots 505, the inside of the T-slot 505 is movably connected to a T-bar 506, and the outer surface of the T-bar 506 is fixedly connected to an L-shaped fixing plate 507.

[0041] By rotating the L-shaped fixing plate 507, the L-shaped fixing plate 507 can drive the T-shaped bar 506 to move inside the T-shaped slot 505, so that the L-shaped fixing plate 507 is no longer locked on the flip cover 504, and then the flip cover 504 is rotated so that the flip cover 504 no longer blocks the taking slot 503. At this time, the operator can pull the stirring rack 401 upward through the taking slot 503, so that the stirring rack 401 drives the corresponding conical filter box 301 to move out of the interior of the reaction cylinder 1 through the taking slot 503, and at the same time continuously push the support roller 2. By rotating, all the conical filter cartridges 301 can be moved out of the inner control of the reaction cylinder 1 through the taking-in slot 503. In the above arrangement, the arrangement of the T-slot 505, the T-bar 506 and the L-shaped fixing plate 507 enables the flip cover 504 to have high stability when shielding the taking-in slot 503. At the same time, the shielding plate 501 and the flip cover 504 can shield the top of the reaction cylinder 1, so that the heat generated when heating the starch suspension and the catalytic solution inside the reaction cylinder 1 is not easy to dissipate from the inside of the reaction cylinder 1, and at the same time, it will not hinder the removal of the conical filter cartridges 301.

[0042] In one embodiment, for the above-mentioned lifting assembly 6, the lifting assembly 6 includes a mounting frame 601, the mounting frame 601 is fixedly connected to the outer surface of the reaction cylinder 1, and a hydraulic cylinder 602 is fixedly installed on the top of the mounting frame 601. The output end of the hydraulic cylinder 602 passes through the mounting frame 601 and is fixedly installed together with the baffle 501.

[0043] By driving the hydraulic cylinder 602, the hydraulic cylinder 602 drives the baffle plate 501 to move upward, and the baffle plate 501 drives the multiple conical filter boxes 301 to move upward through the support roller 2, so that the bottom of the conical filter box 301 is no longer in contact with the bottom of the inner wall of the reaction cylinder 1. This arrangement allows the supernatant to flow between the conical filter box 301 and the reaction cylinder 1 and be directly discharged to the outside of the reaction cylinder 1. The above arrangement ensures that the carbon powder accumulated inside the conical filter box 301 will not hinder the discharge of the supernatant when the supernatant is discharged.

[0044] In one embodiment, for the above-mentioned driving component 7, the driving component 7 includes a discharge pipe 701, the discharge pipe 701 is fixedly connected to the bottom of the reaction cylinder 1, and a motor 702 is fixedly installed at the bottom of the discharge pipe 701, and the output end of the motor 702 is fixedly connected to a driving rod 703. A slot 704 is provided at the bottom end of the support roller 2, and the driving rod 703 passes through the discharge pipe 701 and is movably connected to the slot 704. A driving groove 705 is provided on the inner wall of the slot 704, and a driving bar 706 is movably connected to the inner wall of the driving groove 705, and the driving bar 706 is fixedly connected to the driving rod 703.

[0045] By driving the motor 702, the motor 702 drives the driving rod 703 to rotate, and the driving bar 706 on the driving rod 703 drives the supporting roller 2 to rotate through the driving slot 705, so that the supporting roller 2 can drive multiple conical filter boxes 301 and the stirring frame 401 to rotate. When the supporting roller 2 moves upward, the driving rod 703 can slide inside the slot 704, and the driving bar 706 slides inside the driving slot 705. This setting ensures that no matter how the supporting roller 2 moves up and down, the driving rod 703 can always keep driving the supporting roller 2 under the drive of the driving bar 706 and the driving slot 705. At the same time, a sealing component is provided at the connection between the driving rod 703 and the discharge pipe 701, so that the driving rod 703 can maintain normal rotation while the sealing of the connection with the discharge pipe 701 can also be guaranteed.

[0046] In one embodiment, for the reaction cylinder 1 , a support cylinder 8 is fixedly connected to the bottom of the reaction cylinder 1 , and a solenoid valve 9 is provided inside the discharge pipe 701 .

[0047] By controlling the solenoid valve 9, the supernatant inside the reaction tube 1 can flow out through the discharge pipe 701, which is relatively convenient to operate. At the same time, the support tube 8 can support the reaction tube 1, so that the stability of the reaction tube 1 during operation can be guaranteed.

[0048] According to the above technical solution, 1. by setting the collecting component 3, the carbon powder can be directly precipitated inside the collecting component 3 after the reaction of the catalytic solution and the starch suspension is completed. When the supernatant is discharged, the carbon powder will not be discharged together with the supernatant under the obstruction of the collecting component 3. At the same time, the collecting component 3 can be lifted out of the interior of the reaction cylinder 1 by the stirring component 4 and the collected carbon powder can be poured out outside the reaction cylinder 1. The above arrangement makes it more convenient to collect the carbon powder inside the reaction cylinder 1; 2. by the positioning groove 302 and the positioning bar 303, the sleeve 305 can be directly sleeved on the L-shaped The outer surface of the support rod 304, the limiting rod 403 can be directly moved to the inside of the corresponding limiting groove 402. The above arrangement makes it convenient to move the conical filter box 301 and the stirring frame 401 to the outside of the support roller 2. At the same time, when the support roller 2 drives the conical filter box 301 and the stirring frame 401 to rotate, the positioning groove 302 cooperates with the positioning bar 303, the sleeve 305 cooperates with the L-shaped support rod 304, and the limiting groove 402 cooperates with the limiting rod 403, so that the stability of the connection between the conical filter box 301 and the stirring frame 401 can be guaranteed when they are rotated driven by the support roller 2.
