[0034] Refer to Figures 1 to 3 , an embodiment provided by the present invention: a chemical reaction device, including a reaction tank 1 for reacting raw materials.

The outside of the driven shaft 7 is fixedly connected with a plurality of stirring rods 8 for stirring and mixing the raw materials to improve the reaction rate;

[0035] A support ring 10 is fixedly connected to the top end of the driven shaft 7 to limit the driven shaft 7 and prevent the driven shaft 7 from jittering. The outside of the support ring 10 is rotatably connected to the inner wall of the top end of the reaction tank 1, enabling the support ring 10 to rotate stably. Scrapers 9 are fixedly connected to the far sides of multiple stirring rods 8 to clean the inner wall of the reaction tank 1. A push plate 12 is fixedly connected to the top side of the driven shaft 7, and the rotation of the driven shaft 7 is used to push the push plate 12 to slide. Strip-shaped openings 13 are formed in the left and right sides of the inner wall of the connection box 3 to limit the movement of subsequent components. A driven bevel gear 11 is fixedly connected to the top side of the push plate 12, and the driving bevel gear 6 is meshed with the driven bevel gear 11. After the driving bevel gear 6 transmits the force to the driven bevel gear 11;

[0036] the driven bevel gear 11 will drive the push plate 12 to rotate. Force-receiving plates 14 are slidably connected to the inner walls of the front and rear ends of the connection box 3 to receive the thrust of the push plate 12. Connecting plates 15 are fixedly connected to the far sides of the two force-receiving plates 14 to transmit the sliding force to the connecting plates 15. A reset assembly for resetting the connecting plates 15 is fixedly connected to the top side of the connecting plates 15. A fixing rod 18 is slidably connected to the inner wall of the reset assembly to limit the reset assembly. The reset assembly includes a connecting block 17, and the bottom side of the connecting block 17 is fixedly connected to the top side of the connecting plate 15 to provide a supporting force for the connecting block 17. The far sides of the two fixing rods 18 are respectively fixedly connected to the front and rear sides of the inner wall of the connection box 3 to prevent the fixing rod 18 from shifting. A spring 19 is sleeved on the outside of the fixing rod 18.

[0037] Refer to Figure 2 、 Figure 4 and Figure 5 For each pair of springs 19, the adjacent ends are respectively fixedly connected to the far sides of the two connecting blocks 17 to limit and fix the springs 19, enabling the springs 19 to be evenly stressed. Circular plates 20 are fixedly connected to the adjacent sides of the two fixing rods 18 to prevent the springs 19 from slipping. Storage frames 16 are fixedly connected to the far sides of the two connecting plates 15 to pour raw materials into the inner wall of the reaction tank 1. Sealing plates 21 are fixedly connected to the far sides of the two storage frames 16 to prevent the raw materials from leaking out. Feeding frames 22 are fixedly connected to the front and rear ends of the top side of the reaction tank 1 to store raw materials. The outside of the storage frame 16 is slidably connected to the inner wall of the bottom end of the feeding frame 22, enabling the storage frame 16 to slide horizontally to take out the raw materials inside the feeding frame 22. A plurality of support legs are fixedly connected to the bottom side of the reaction tank 1 to provide stable support for the reaction tank 1. Feeding openings 23 are formed in the left and right ends of the top side of the reaction tank 1 to facilitate the raw materials inside the storage frame 16 to be poured into the inside of the reaction tank 1.

[0038] Refer to Figure 1 、 Figure 6 and Figure 7, on the left side of the reaction tank 1, there is a strip-shaped box 24 fixedly connected, which is used to protect the internal components. At the left end of the bottom of the strip-shaped box 24, there is an air outlet pipe 25 fixedly connected, which is used to export the toxic gas. At the left end of the bottom of the strip-shaped box 24, there is a filter plate 26 slidably connected, which is used to filter the impurities in the toxic gas. At the left end of the driving assembly, there is a driving wheel 27 fixedly connected. Outside the driving wheel 27, there is a belt 28 sleeved. The left end of the rotating shaft 5 is fixedly connected to the inner wall of the driving wheel 27. Through the rotating shaft 5, the rotating force is transmitted to the driving wheel 27, and then the power is transmitted to the belt 28 by using friction.

[0039] On the inner wall of the bottom end of the strip-shaped box 24, there are two support plates 29 fixedly connected, which provide support force for the subsequent components. Inside the two support plates 29, there is a rotating shaft 30 rotatably connected, so that the rotating shaft 30 can rotate stably. At the left and right ends of the rotating shaft 30, there are limit rings 32 fixedly connected, which prevent the rotating shaft 30 from slipping. Outside the rotating shaft 30, there is a driven wheel 31 fixedly connected. At the left side of the rotating shaft 30, there is a rotating column 33 fixedly connected. Outside the driven wheel 31, it is sleeved inside the belt 28. After the power is transmitted to the driven wheel 31 through the belt 28, the driven wheel 31 transmits the force to the rotating shaft 30 for rotation. Outside the rotating column 33, there are a plurality of rotating fan blades 34 fixedly connected, which are used to draw out the toxic gas.

[0040] Working principle: Place the reaction raw materials inside the feeding frame 22, and block the raw materials inside the feeding frame 22 with the sealing plate 21. Then, drive the rotating shaft 5 to rotate by the driving motor 4, thereby driving the driving bevel gear 6 to rotate, and then driving the engaged driven bevel gear 11 to rotate. As the driven bevel gear 11 rotates, it will drive the push plate 12 to rotate. Then, the push plate 12 will push the two force-receiving plates 14 to slide away from each other, thereby pushing the connecting plate 15 to slide, and then pushing the storage frame 16 to slide and pushing the sealing plate 21 to no longer block the feeding frame 22. The storage frame 16 will slide to the bottom side of the feeding frame 22. At this time, the raw materials inside the feeding frame 22 will fall into the storage frame 16. At this time, the connecting plate 15 will also push the connecting block 17 to slide and compress the spring 19, so that the spring 19 can store elastic potential energy, and then give the connecting plate 15 a force to drive the storage frame 16 to reset. After the push plate 12 no longer contacts the force-receiving plate 14, the reset force of the spring 19 at this time will be transmitted to the connecting block 17, so that the connecting block 17 can drive the connecting plate 15 to slide, thereby driving the storage frame 16 to slide back to its original position, making the storage frame 16 perpendicular to the blanking opening 23. Then, the raw materials will fall from the storage frame 16 and land on the inner wall of the reaction tank 1. With the rotation of the push plate 12, indirectly, the force-receiving plate 14 and the reset force provided after the spring 19 is compressed cooperate with each other, so that the storage frame 16 can quantitatively and reciprocally bring the raw materials inside the feeding frame 22 into the reaction tank 1. At this time, the contact between raw material molecules is relatively frequent, thereby improving work efficiency; at the same time, the push plate 12 will also drive the driven shaft 7 to rotate, thereby driving the stirring rod 8 to rotate to stir the raw materials to accelerate the reaction efficiency, and at the same time, the stirring rod 8 will also drive the scraping plate 9 to clean the inner wall of the reaction tank 1;

[0041] During the reaction process, toxic gases will also be generated. At this time, the rotating shaft 5 will also drive the driving wheel 27 to rotate, and then drive the belt 28 to rotate, thereby driving the driven wheel 31 to rotate. The rotating shaft 30 is driven by the driven wheel 31 to rotate, thereby driving the rotating column 33 to rotate, and then driving a plurality of rotating fan blades 34 to rotate. Then, the toxic gases generated inside the reaction tank 1 will be led into the strip-shaped box 24 and blown out from the air outlet pipe 25, thereby avoiding the impact of toxic gases on the staff and improving work safety.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
