Description

Technical Field

[0001] The utility model relates to the technical field of silicon-carbon negative electrode materials, in particular to a reactor for manufacturing silicon-carbon negative electrode materials. Background Art

[0002] Silicon-carbon negative electrode material refers to negative electrode material with silicon and carbon as the main components. Silicon-carbon negative electrode material has attracted much attention due to its excellent electrochemical properties. First of all, silicon-carbon negative electrode material has high specific capacity. Compared with traditional graphite negative electrode material, silicon-carbon negative electrode material has higher specific capacity. When making silicon-carbon negative electrode material, a reactor is needed.

[0003] In the prior art, a Chinese utility model with publication number CN220546943U discloses a reactor for making silicon-carbon negative electrode materials, comprising a shell, a feed assembly being installed on the surface of the shell, the feed assembly comprising a feed mechanism for injecting silane into the shell and a mounting mechanism for fixing the feed mechanism, the mounting mechanism having an annular fixing member composed of two semi-annular members, the feed mechanism being installed inside the semi-annular members, the utility model is provided with a mounting mechanism, two clamping rings are fixed to the surface of the shell by connecting sheets and studs, and the shell is loaded with material by the internal feed mechanism, a clamping groove is provided so that the shell will not slide out of the inside of the clamping ring due to its own weight, a through hole is provided to facilitate the feeding of material to the shell, silane gas enters the inside of the chamber from the feed port, and then enters the inside of each discharge port from the chamber, the discharge port is embedded in the inside of the through hole, and silane gas enters the inside of the shell from the through hole.

[0004] In the above technology, the outer shell is supported from both sides by a mounting mechanism, and then the silane gas is injected into the interior of the outer shell from multiple angles through a feeding mechanism inside the mounting mechanism for reaction, thereby increasing the contact area between silane and porous carbon. However, when injecting the silane gas, a certain amount of time is required to ensure that the gas flows fully and fills the entire interior of the outer shell.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] Embodiment 1:

[0026] See also Figure 1-4 The utility model provides a technical solution: a reactor for making silicon-carbon negative electrode materials, comprising: a bottom plate 1, a support frame 2 is fixed on the top surface of the bottom plate 1, a reaction box 3 is fixed on the inner bottom surface of the support frame 2, a storage box 4 is fixed on the top surface of the support frame 2, and silane gas is stored in the storage box 4; a dispersion pipe 5 is connected and fixed to the bottom surface of the storage box 4, and the other end of the dispersion pipe 5 is respectively connected and fixed to one side of the reaction box 3, and fixing holes 6 are respectively opened on both sides of the support frame 2, and a driving motor 7 is fixed inside the fixing hole 6; a placement frame 8 is rotatably arranged inside the reaction box 3, and a top cover is rotatably connected to the top surface of the placement frame 8 through a hinge, a buckle is arranged on one side of the placement frame 8, and support columns 9 are rotatably arranged on both sides of the placement frame 8, and two clamping blocks are fixed on the outer wall of the support column 9, and the two ends of the support column 9 respectively penetrate the two sides of the reaction box 3, and one end of the support column 9 is fixed to the output shaft of the driving motor 7, and fans 10 are respectively fixed on both sides of the inner wall of the reaction box 3, and the fan 10 is electrically connected to the external control device.

[0027] Silane gas is transported to the reaction box 3 from multiple directions through the dispersion tube 5, and then the output shaft of the driving motor 7 drives the support column 9 to rotate, so that the placement frame 8 can be rotated, so that the porous carbon in the placement frame 8 can be turned over to avoid stacking together, so that it can be fully contacted with the silane gas, and through continuous rotation, the reaction can be accelerated, the reaction time can be shortened, and the work efficiency can be improved. During the reaction, air is blown by the fan 10 to increase the air circulation in the reaction box 3, so as to avoid the accumulation of silane gas and cause slow circulation speed, so that the silane gas can quickly fill the entire reaction box 3, so that the silane gas is in full contact with the porous carbon.

[0028] Embodiment 2:

[0029] like Figure 1-4 As shown, a reactor for manufacturing silicon-carbon negative electrode materials disclosed in Example 2 of the utility model has a structure that is basically the same as that in Example 1, except that sealing rings 11 are fixed inside the connecting holes on both sides of the reaction box 3, the support columns 9 and the sealing rings 11 are movably inserted, and a receiving box 12 is movably arranged inside the reaction box 3, and three pulling rings 13 are fixed to one side of the receiving box 12.

[0030] The sealing ring 11 can prevent silane gas leakage, thereby saving resources. The porous carbon after the reaction can be collected by the receiving box 12, and then the receiving box 12 can be taken out by pulling the ring 13, thereby preventing the porous carbon from scattering everywhere, thus bringing convenience to the staff.

[0031] Embodiment three:

[0032] like Figure 1-4As shown, a reactor for making silicon-carbon negative electrode materials disclosed in Example 3 of the utility model has a structure that is basically the same as that in Example 2, except that a removal hole 14 is provided on one side of the reaction box 3, and a protective plate 15 is rotatably connected to one side of the reaction box 3 through a hinge, and the protective plate 15 corresponds to the removal hole 14, and gas sensors 16 are respectively fixed on both sides of the inner wall of the reaction box 3, and the gas sensor 16 is electrically connected to an external control device, and a perspective window 17 is provided on one side of the reaction box 3, and connecting plates 18 are respectively fixed on both sides of the placement frame 8, and an insertion hole 19 is provided on one side of the connecting plate 18, and two clamping grooves are provided on the inner wall of the insertion hole 19; a spring 20 is fixed inside the insertion hole 19, and a pressing plate 21 is fixed to the other end of the spring 20, and the support column 9 is movably inserted into the insertion hole 19.

[0033] The receiving box 12 can be easily taken out through the removal hole 14, and then blocked by the protective plate 15, thereby preventing silane gas from leaking out of the removal hole 14. The concentration of silane gas can be detected by the gas sensor 16 to prevent the concentration from being too high when taking out and causing harm to human health. The transparent window 17 allows the staff to intuitively observe the reaction situation in the reaction box 3. The support column 9 contacts the pressing plate 21, thereby squeezing the spring 20, so that the placement frame 8 can be installed, and then it can be quickly disassembled after the reaction to take out the material and clean it.

[0034] The specific scheme is as follows: the staff first places the porous carbon into the placement frame 8, and then transports the silane gas from multiple directions to the reaction box 3 through the dispersion tube 5, and then drives the support column 9 to rotate by rotating the output shaft of the driving motor 7, so that the placement frame 8 can be rotated, so that the porous carbon in the placement frame 8 can be turned over to avoid stacking together, so that it can be fully contacted with the silane gas, and through continuous rotation, the reaction can be accelerated, the reaction time can be shortened, and the work efficiency can be improved. During the reaction, air is blown by the fan 10 to increase the air circulation in the reaction box 3, so as to avoid the accumulation of silane gas and cause slow circulation speed, so that the silane gas can quickly fill the entire reaction box 3, so that the silane gas is in full contact with the porous carbon.
