[0002] A stirring reaction kettle is a key piece of equipment widely used in industries such as chemical engineering, pharmaceuticals, food, and metallurgy. It is mainly used for the mixing, reaction, mass transfer, and heat transfer processes between different materials. Its core function is to make the reactants fully contact under suitable temperature, pressure, and concentration conditions through mechanical stirring, thereby accelerating chemical reactions or physical mixing processes, improving production efficiency and product quality. With the continuous improvement of the requirements for refinement, high efficiency, and environmental protection in modern industry, the design and manufacturing technologies of stirring reaction kettles are also constantly progressing to meet increasingly complex process requirements.

[0003] In the prior art, in the solid-liquid mixing and gas-liquid mixing reactions of the stirring reaction kettle for manufacturing chemical products, the stirring uniformity is poor, making it impossible for the materials to be fully mixed, resulting in incomplete reactions and thus affecting product quality. For reactions that generate gas, when the pressure in the reaction kettle increases, it is difficult to adjust the pressure in a timely and effective manner, which may pose safety risks due to excessive pressure. For granular or highly viscous materials, it is easy to block the discharge port during discharging, affecting the smooth progress of discharging and resulting in reduced production efficiency.

[0036] In this embodiment, the transmission structure 4 includes a fixed frame 401. The fixed frame 401 is arranged at a position on the upper end surface of the cover plate 10, close to one side and at the center. At the center of the upper end surface of the fixed frame 401, there is a first servo motor 402. The output end of the first servo motor 402 is fixedly connected with a first gear 403. At the center of the upper end surface of the cover plate 10, there is a second gear 404. At the front and rear positions at the center of the upper end surface of the cover plate 10, there are couplings 405. The two couplings 405 are composed of two semi - circles to form a circle. At the center of the upper end surface of the fixed frame 401, there is a stabilizing frame 406. The stabilizing frame 406 and the first servo motor 402 are mutually adapted. The first gear 403 and the second gear 404 are meshed with each other. At the upper and lower positions, close to the center of the rear end surface of the coupling 405 at the rear position, there are hexagon socket head cap screws. One end of the upper hexagon socket head cap screw penetrates through the rear end surface of the coupling 405 at the rear position, the rear end surface of the second gear 404, and the front inner wall of the coupling 405 at the front position and reaches the front end surface of the coupling 405 at the front position, and the end is threadedly connected inside the coupling 405 at the front position. One end of the lower hexagon socket head cap screw penetrates through the rear end surface of the coupling 405 at the rear position, the rear end surface of the transmission rod 5, and the front inner wall of the coupling 405 at the front position and reaches the front end surface of the coupling 405 at the front position, and the end is threadedly connected inside the coupling 405 at the front position.

[0037] In this embodiment, before the chemical product enters the inner tank 202, by starting the first servo motor 402 to drive the first gear 403 to rotate, the first gear 403 and the second gear 404 are meshed with each other, so that the second gear 404 rotates accordingly. The second gear 404 and the transmission rod 5 are connected through the coupling 405. The first gear 403 drives the second gear 404 to rotate, and the second gear 404 drives the transmission rod 5 to rotate.

[0038] In this embodiment, the stirring structure 6 includes a spiral disk 601 wound around the center of the outer wall of the transmission rod 5. A connecting frame 602 is provided on the outer wall of the transmission rod 5 at the upper end of the spiral disk 601. Four stirring blades 603 are arranged in a circular pattern on the lower end face of the connecting frame 602. A plurality of flow guiding grooves 604 are arranged horizontally at the center of one side wall of the four stirring blades 603. Four connecting plates 605 are arranged in a circular pattern on the lower end face of the connecting frame 602. Scrapers 606 are provided at one end of each of the four connecting plates 605. The four scrapers 606 are in close contact with the inner side wall of the inner tank 202. When the transmission rod 5 rotates, the spiral disk 601 wound around the center of its outer wall rotates accordingly. The four stirring blades 603 are driven by the spiral disk 601 to rotate around the axis of the transmission rod 5. And through the flow guiding grooves 604, the flow of the liquid material during the stirring process is made smoother and a specific flow pattern is formed, improving the stirring effect and the uniformity of the reaction. At the same time, the four scrapers 606 are driven to rotate by the connecting frame 602. The scrapers 606 are in close contact with the inner side wall of the inner tank 202, and can continuously scrape the inner side wall of the inner tank 202 to prevent the material from adhering to the wall of the inner tank 202 and ensure the full progress of the reaction.

[0039] In this embodiment, the anti-blocking structure 7 includes a mounting plate 701 provided at the lower center of the outer side wall of the box body 1. A second servo motor 702 is provided at the center of one side wall of the mounting plate 701. The output end of the second servo motor 702 penetrates through one side wall of the mounting plate 701, one side wall of the box body 1 and one side wall of the inner tank 202 and extends into the inner part of the inner tank 202, and is fixedly connected to a spiral stirring rod 703 at the end. When discharging materials, the second servo motor 702 is started to drive the spiral stirring rod 703 to rotate, stirring the materials near the discharge port to prevent granular or highly viscous materials from blocking the liquid outlet of the inner tank 202 before discharging, ensuring that the materials can smoothly pass through to the discharging structure 9.

[0040] In this embodiment, the pressure relief structure 8 includes a pressure relief pipe 801. The pressure relief pipe 801 is arranged at a position on the upper end face of the box body 1 near the other side and at the center. At the center of the lower end face of the pressure relief pipe 801, there is a pressure inlet 802. At positions near the lower part of the front end face center and the lower part of the rear end face center of the pressure relief pipe 801, there are pressure outlet ports 803. At the center of the upper end face of the pressure inlet 802, there is a lower plate 804. At the center of the upper end face of the lower plate 804, there is a sleeve 805. At the center of the lower inner wall of the sleeve 805, there is a compression spring 806. At the center of the upper end face of the compression spring 806, there is an inner pipe 807. At the center of the upper end face of the inner pipe 807, there is an upper plate 808. During operation, when the pressure in the reactor is too high, the gas enters the pressure relief pipe 801 from the pressure inlet 802, and a pressure balancing device is formed by the lower plate 804, the sleeve 805, the compression spring 806, the inner pipe 807 and the upper plate 808. When the pressure in the inner tank 202 reaches a certain level, the pressure pushes the upper plate 808 to move upward against the elastic force of the compression spring 806, so that the pressure inlet 802 is opened, and the gas is discharged through the pressure outlet port 803, reducing the pressure in the reactor and ensuring the safety and stability of the reaction process.

[0041] In this embodiment, the discharging structure 9 includes a discharging pipe 901. The discharging pipe 901 is arranged at the center of the lower end face of the box body 1. At a position near the lower part of the center of one side wall of the discharging pipe 901, there is a fixing plate 902. At the center of one side wall of the fixing plate 902, there is a third servo motor 903. The output end of the third servo motor 903 penetrates through one side wall of the fixing plate 902 and communicates with one side wall of the discharging pipe 901 to reach the inside of the discharging pipe 901, and the end is fixedly connected with a gate valve 904. When the reaction ends and the discharging condition is reached, by starting the third servo motor 903 to drive the gate valve 904 to rotate, the discharging pipe 901 is opened, and the reacted material in the reactor flows out from the discharging pipe 901, completing the discharging operation after the chemical product is manufactured.

[0042] Implementation scheme: Set the working parameters of the heating pipe 203 through the control panel 11. After the heating pipe 203 is started, the heating pipe 203 starts to release heat, and the heat is transferred to the inner tank 202 through the cavity 201, increasing the temperature of the inner tank 202. Add the chemical products that need to be stirred and reacted into the inner tank 202 of the stirring reactor through the feed hopper 3.

[0043] When chemical products enter the inner tank 202, the first servo motor 402 is started to drive the first gear 403 to rotate. The first gear 403 meshes with the second gear 404, and the power is transmitted to the second gear 404. The two couplings 405 tightly connect the second gear 404 and the transmission rod 5 through hexagon socket head cap screws, so that the rotation of the second gear 404 drives the transmission rod 5 to start rotating. The rotation of the transmission rod 5 drives the spiral disk 601 to rotate. The spiral disk 601 drives the connecting frame 602 to rotate, and the connecting frame 602 drives the stirring blades 603 to start rotating at a high speed. The flow guide grooves 604 on the stirring blades 603 can guide the materials to form a specific flow path, enhancing the collision, shearing and mixing effects between the materials, ensuring that the reaction proceeds in a more uniform material environment. At the same time, the connecting frame 602 drives the scraper 606 to rotate around the inner side wall of the inner tank 202. The scraper 606 is close to the wall of the inner tank 202, preventing the materials from adhering and accumulating on the wall of the inner tank 202, ensuring the normal progress of the reaction and the temperature uniformity of the wall of the inner tank 202.

[0044] The chemical reaction begins in the inner tank 202. During the reaction process, the temperature inside the reaction kettle will rise. For reactions that generate gas, the pressure inside the reaction kettle will gradually increase. When the pressure inside the reaction kettle rises to a certain value and exceeds the preset safe pressure range, the gas in the inner tank 202 pushes the upper plate 808 to move upward against the elastic force of the compression spring 806, and the pressure inlet 802 opens. The gas is discharged to the outside of the reaction kettle through the pressure discharge port 803, thereby reducing the pressure inside the reaction kettle. When the pressure drops to an appropriate range, the compression spring 806 returns to its original state, pushing the upper plate 808 to descend and closing the pressure inlet 802, ensuring the stability of the internal environment of the reaction kettle and maintaining the normal progress of the reaction.

[0045] When the reaction is approaching the end, the second servo motor 702 is started to drive the spiral stirring rod 703 to rotate. The spiral stirring rod 703 stirs the materials near the discharge port to prevent the materials from caking and blocking here due to viscosity and crystallization, etc., ensuring that the subsequent discharging process can proceed smoothly. When the chemical reaction is completed and it is determined through detection that the product meets the quality requirements and discharging starts, the third servo motor 903 is started to drive the gate valve 904 to rotate, so that the gate valve 904 opens. The materials in the inner tank 202 are discharged from the reaction kettle through the discharge pipe 901 under the action of gravity. After the discharging is completed, the third servo motor 903 controls the gate valve 904 to close, preventing the remaining materials from leaking and preparing for the next production.

[0046] Although the preferred embodiments of the present invention have been described, additional changes and modifications can be made to these embodiments by those skilled in the art once they learn of the basic inventive concept. Obviously, those skilled in the art can make various changes and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of equivalent technology of the present invention, the present invention is also intended to include these modifications and variations.
