Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0034] like Figure 1-5 As shown, this embodiment proposes a reaction device for producing nano-scale silicon oxide spherical powder, including a tank body 1, a reaction mechanism 2 is arranged outside the tank body 1, a voltage stabilizing component 3 is arranged on the top of the tank body 1, and a discharge component 4 is arranged at the bottom of the tank body 1.
[0035] like Figure 4 As shown, the reaction mechanism 2 includes a feed pipe 201, an exhaust pipe 202, a round rod 203, a stirring rod 204, a motor 205, a cavity 206 and a heating wire 207. The feed pipe 201 and the exhaust pipe 202 are both connected and arranged at the top of the tank body 1. The round rod 203 is rotatably connected to the inside of the tank body 1. The stirring rod 204 is arranged on the outer wall of the round rod 203. The motor 205 is fixedly connected to the top of the round rod 203. The cavity 206 is opened in the wall of the tank body 1. The heating wire 207 is arranged inside the cavity 206. The output end of the motor 205 is coaxially arranged with the top of the round rod 203. It can also drive the round rod 203 to rotate. The number of stirring rods 204 is several and evenly distributed along the height direction of the round rod 203. The length of the stirring rod 204 at the bottom end of the round rod 203 is shorter than the length of the stirring rod 204 at the top end of the round rod 203. When in use, the silicon source, catalyst and solvent are poured into the tank body 1 from the feed pipe 201, and then the heating wire 207 can heat the inside of the tank body 1 in all directions, so that the material inside the tank body 1 can be fully heated and reacted, and then the motor 205 drives the round rod 203 and the stirring rod 204 to rotate, thereby accelerating the reaction speed between the materials.
[0036] like Figure 5As shown, the voltage stabilizing component 3 includes a lifting slot 301, a lifting rod 302, a limiting plate 303, a spring 304 and a top cover 305. The lifting slot 301 is opened at the top of the exhaust pipe 202, the lifting rod 302 is slidably connected to the inside of the lifting slot 301, the limiting plate 303 is fixedly connected to the bottom end of the lifting rod 302, the spring 304 is fixedly connected to the top of the limiting plate 303 and sleeved on the outside of the lifting rod 302, and the top cover 305 is fixedly connected to the top of the lifting rod 302 and fits tightly with the top of the exhaust pipe 202. The number of lifting slots 301, lifting rods 302, limiting plates 303 and springs 304 is as follows: There are four of them and they are distributed in a circle along the central axis of the exhaust pipe 202. The top of the spring 304 is fixedly connected to the inner top wall of the lifting groove 301. When in use, the liquid in the tank body 1 evaporates to produce steam, which will then fill the tank body 1 with gas. At this time, the gas will pass through the exhaust pipe 202 to impact the top cover 305, and then the spring 304 will contract, and the lifting rod 302 will move away from the tank body 1, thereby causing the top cover 305 to detach from the exhaust pipe 202, thereby discharging the steam. After the steam is discharged, the spring 304 drives the lifting rod 302 and the top cover 305 to reset, thereby ensuring the gas balance inside the tank body 1.
[0037] like Figure 4 As shown, the discharge assembly 4 includes a discharge pipe 401, a filter screen 402, a discharge pipe 403, a first solenoid valve 404 and a second solenoid valve 405. The discharge pipe 401 is connected and arranged at the bottom of the tank body 1, the filter screen 402 is inclined and arranged inside the discharge pipe 401, the discharge pipe 403 is connected and arranged on the outer wall of the discharge pipe 401, the first solenoid valve 404 and the second solenoid valve 405 are respectively arranged on the outside of the discharge pipe 401 and the discharge pipe 403, the filter screen 402 is inclined and the lower end of the filter screen 402 is located at one end of the discharge pipe 403. After the material reaction is completed, the first solenoid valve 404 is opened to discharge the waste liquid inside the tank body 1 to the outside through the filter screen 402 and the discharge pipe 401. After the waste liquid is discharged, the second solenoid valve 405 is opened to discharge the material staying on the top of the filter screen 402 from the discharge pipe 403 to the outside.
[0038] like Figure 1 As shown, a support rod 5 is bolted to the top of the tank body 1, a support plate 6 is bolted to the top of the support rod 5, and the top of the support plate 6 is bolted to the bottom of the motor 205. There are three support rods 5 and they are distributed circumferentially along the central axis of the round rod 203. When in use, the support rod 5 can support the support plate 6, and then support the motor 205 to prevent the tank body 1 from overheating and affecting the normal operation of the motor 205.
[0039] like Figure 1As shown, the top of the feed pipe 201 is threadedly connected with a sealing cover 7 to prevent gas from being discharged from the feed pipe 201. When in use, the sealing cover 7 can block the feed pipe 201 to prevent the gas generated during the reaction from being discharged from the discharge pipe 403 and being inhaled by external personnel adding materials.
[0040] like Figure 1 As shown, an observation tube 8 is provided at the top of the tank body 1, and a transparent plate 9 is provided inside the observation tube 8. When in use, outside workers can observe the reaction situation inside the tank body 1 through the observation tube 8 and the transparent plate 9 so as to respond in time.
[0041] like Figure 1 As shown, the bottom of the tank body 1 is bolted with support legs 10 , and there are three support legs 10 distributed circumferentially along the central axis of the tank body 1 . The user can support the device with the support legs 10 , thereby ensuring the normal operation of the discharge pipe 401 .
[0042] like Figure 1 As shown, the tank body 1, the round rod 203 and the stirring rod 204 are made of stainless steel. When in use, the tank body 1, the round rod 203 and the stirring rod 204 have corrosion resistance and can ensure stability and safety during the reaction process.
[0043] like Figure 1 As shown, the support rod 5 and the support plate 6 are both made of rock wool. When in use, the support rod 5 and the support plate 6 made of rock wool have excellent heat insulation performance, preventing the motor 205 from being overheated.
[0044] like Figure 1 As shown, the material of the transparent plate 9 is high borosilicate glass. When in use, the transparent plate 9 made of high borosilicate glass has the effects of high temperature resistance and low expansion rate, which prevents the internal temperature of the tank body 1 from being too high and causing damage to the transparent plate 9.
[0045] Specifically, when the reaction device for producing nano-scale silicon oxide spherical powder is used: the motor 205 and the electric heating wire 207 are connected to an external power source and started, and then the silicon source, the catalyst and the solvent are poured into the tank body 1 from the feed pipe 201, and then the electric heating wire 207 can heat the inside of the tank body 1 in all directions, so that the materials in the tank body 1 can be fully heated and reacted, and then the motor 205 drives the round rod 203 and the stirring rod 204 to rotate, so as to accelerate the reaction speed between the materials. During the reaction, the liquid in the tank body 1 evaporates to generate steam, which will fill the tank body 1 with gas. At this time, the gas will pass through the exhaust pipe 205. The air pipe 202 impacts the top cover 305, and then the spring 304 contracts, and the lifting rod 302 moves away from the tank body 1, thereby causing the top cover 305 to separate from the exhaust pipe 202, thereby discharging the steam. After the steam is discharged, the spring 304 drives the lifting rod 302 and the top cover 305 to reset, thereby ensuring the gas balance inside the tank body 1. After the material reaction is completed, the first solenoid valve 404 is opened to discharge the waste liquid inside the tank body 1 to the outside through the filter screen 402 and the drain pipe 401. After the waste liquid is discharged, the second solenoid valve 405 is opened to discharge the material remaining on the top of the filter screen 402 from the discharge pipe 403 to the outside.
[0046] All technical features in this embodiment can be freely combined according to actual needs.
[0047] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
