DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Please refer to Figures 1-4 , a reaction device for producing a silicon-deposited negative electrode material of a supercapacitor activated carbon carrier, including a stable frame 1. The number of the stable frames 1 is two. A feeding pipe 2 is installed on the surface of the left stable frame 1. By setting the feeding pipe 2, it can extend into the processing cylinder 4 to meet the requirement of adding materials into the processing cylinder 4. A driving component 6 is installed on the surface of the right stable frame 1. The driving component 6 includes a driving motor 601 and a positioning shaft 605. The number of the positioning shafts 605 is two. Pulley wheels 603 are fixedly sleeved on the surface of the positioning shafts 605. An auxiliary belt 604 is sleeved between the two pulley wheels 603 and is connected by belt drive through the auxiliary belt 604. By setting the pulley wheels 603, the auxiliary belt 604 and the positioning shafts 605, the function of belt drive can be achieved. Driven by the driving motor 601, the processing cylinder 4 can rotate in a circle. A processing cylinder 4 is movably installed on the top of the surface of the stable frame 1. A guiding and rotating component 5 is fixedly installed on the surface of the processing cylinder 4. The guiding and rotating component 5 includes an extension cylinder 502. A spiral steel wire 501 is fixedly connected to the inner wall of the extension cylinder 502. By setting the spiral steel wire 501, the spiral shape of itself can be used to guide the crushing balls 7 put into the extension cylinder 502, so that the crushing balls 7 rotate to further crush the materials in the extension cylinder 502. Crushing balls 7 are arranged in the inner cavity of the processing cylinder 4. Discharge valves 8 are communicated with both the left and right sides of the bottom of the inner cavity of the processing cylinder 4. By setting the discharge valves 8, the materials in the processing cylinder 4 can be discharged when they are in the open state;

[0021] Please refer to Figure 3 , a mounting plate 602 is fixedly connected to the surface of the stable frame 1. The bottom of the driving motor 601 is bolted to the top of the mounting plate 602. By setting the mounting plate 602, the fixed installation requirement of the driving motor 601 can be met;

[0022] Please refer to Figure 3 , the connection between the positioning shaft 605 and the output end of the driving motor 601 and the connection between the positioning shaft 605 and the processing cylinder 4 are both fixedly connected;

[0023] Please refer to Figure 3 and Figure 4 , an empty slot 10 for cooperating with the extension cylinder 502 is penetrated and opened on the outer ring of the processing cylinder 4. By setting the empty slot 10, the fixed installation requirement of the extension cylinder 502 can be met, and the crushing balls 7 are adapted to the extension cylinder 502;

[0024] Please refer to Figure 3 and Figure 4, one end of the extension cylinder 502 away from the processing cylinder 4 is communicated with an air vent valve 503. By setting the air vent valve 503, it can be communicated with an external high-pressure blower in the open state, and then the residual materials in the extension cylinder 502 can be discharged by using high-speed air flow. The number of extension cylinders 502 is several and they are evenly distributed on the processing cylinder 4. The surface of the stabilizing frame 1 is penetrated with positioning grooves 3. By setting the positioning grooves 3, while ensuring the supporting strength of the stabilizing frame 1, the total amount of materials can be reduced and the processing cost can be saved;

[0025] Please refer to Figure 3 , the right end of the feeding pipe 2 extends into the inner cavity of the processing cylinder 4 and is movably connected to the processing cylinder 4 through a sealed bearing;

[0026] Please refer to Figure 2 , a mounting sleeve 9 is fixedly sleeved on the right side of the surface of the feeding pipe 2, and the surface of the mounting sleeve 9 is fixedly connected to the stabilizing frame 1 through bolts. By setting the mounting sleeve 9, the feeding pipe 2 and the stabilizing frame 1 can be connected, thereby ensuring the installation stability of the feeding pipe 2.

[0027] During use, all components are in the initial installation state. First, an appropriate amount of materials are added into the processing cylinder 4 through the feeding pipe 2, and the driving motor 601 is controlled to work. Driven by the pulley 603, the auxiliary belt 604 and the positioning shaft 605, the processing cylinder 4 rotates circumferentially on the stabilizing frame 1, so that the crushing balls 7 displace in the processing cylinder 4 and continuously collide with the materials. At the same time, some materials enter the extension cylinder 502, and some crushing balls 7 also enter the extension cylinder 502. Since the processing cylinder 4 rotates circumferentially, there are centrifugal force and centripetal force when the crushing balls 7 enter the extension cylinder 502, so that the crushing balls 7 contact the spiral steel wire 501. Under the cooperation of the spiral steel wire 501, the crushing balls 7 naturally rotate and can collide and grind with the materials well. The overall processing effect is higher, effectively reducing the processing time. Finally, open the discharge valve 8 to discharge the materials.

[0028] To sum up: For the reaction device used for producing the silicon-immersed negative electrode material of the supercapacitor activated carbon carrier, by setting the processing cylinder 4, the guiding and rotating assembly 5 and the crushing balls 7, it solves the problem that the basic reaction device can only perform simple ball milling processing and does not have the function of rotating grinding and crushing, often requiring a relatively long processing time and having certain limitations.
