[0002] In the modern industrial system, the chemical industry occupies a crucial position. As a key device in the chemical production process, the chemical reaction kettle plays a vital role. With the continuous development and progress of chemical technology, the types of chemical products are increasing day by day, and the production process is becoming more and more complex. Under such circumstances, the performance requirements for chemical reaction kettles are also constantly improving. To ensure the quality of chemical products and the safety of the production process, it is necessary to monitor and precisely control the chemical reactions in the reaction kettle in real time. Sampling analysis is one of the important means to achieve this goal. By sampling the chemical materials at different stages in the reaction kettle, key information such as the progress of the reaction and the composition of the products can be understood, so as to adjust the process parameters in time and optimize the production process.

[0003] In terms of sampling, most of the existing chemical reaction kettles adopt a relatively traditional fixed pipeline connection method. This method usually sets one or more fixed sampling ports on the reaction kettle and connects them to external sampling containers through pipelines. When sampling, the valve needs to be opened to allow the chemical materials in the reaction kettle to flow into the sampling container through the pipeline. However, after sampling, it is often relatively complicated to disassemble the sampling device and specific tools are required for operation.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0034] Refer to Figure 1 - Figure 4, an embodiment provided by the present utility model: a chemical safety reactor convenient for sampling, including a reaction tank 5. Inside the reaction tank 5, a stirring assembly is provided. The stirring assembly is used to stir chemical raw materials to accelerate chemical reactions. A fixed head 19 is fixedly connected to the outer wall of the reaction tank 5. A fixed orifice plate 15 is fixedly connected to the inner wall of the fixed head 19. A telescopic column 17 is fixedly connected to the side wall of the fixed orifice plate 15. One end of the telescopic column 17 is fixedly connected to a conical head 18. A first spring 16 is arranged between the fixed orifice plate 15 and the conical head 18. One end of the first spring 16 is fixedly connected to the side wall of the fixed orifice plate 15, and the other end of the first spring 16 is fixedly connected to the side wall of the conical head 18. An activity ring 20 is slidably connected to the outer wall of the fixed head 19. A second spring 22 is arranged between the fixed head 19 and the activity ring 20. One end of the second spring 22 is fixedly connected to the outer wall of the fixed head 19, and the other end of the second spring 22 is fixedly connected to the inner wall of the activity ring 20. An activity bead 21 is slidably connected inside the fixed head 19. A limit ring 23 is fixedly connected to the outer wall of the fixed head 19. A quick connector 14 is slidably connected to the inner wall of the fixed head 19. A groove 24 is formed on the outer wall of the quick connector 14. A fixed orifice plate 15 is fixedly connected to the inner wall of the quick connector 14. A telescopic column 17 is fixedly connected to the side wall of the fixed orifice plate 15. One end of the telescopic column 17 is fixedly connected to a conical head 18. A first spring 16 is arranged between the fixed orifice plate 15 and the conical head 18. One end of the first spring 16 is fixedly connected to the side wall of the fixed orifice plate 15, and the other end of the first spring 16 is fixedly connected to the side wall of the conical head 18. One end of the quick connector 14 is fixedly connected to a sampling tube 12. One end of the sampling tube 12 is fixedly connected to a cylinder 10. The output end of the cylinder 10 is fixedly connected to an activity block 11. The activity block 11 is slidably connected to the inner wall of the sampling tube 12. A sampling bottle 13 is fixedly connected to the outer wall of the sampling tube 12. The stirring assembly includes a first motor 7. The first motor 7 is fixedly connected to the top of the reaction tank 5. The output end of the first motor 7 is fixedly connected to a stirrer 8. The stirrer 8 is rotatably connected inside the reaction tank 5. An injection tube 6 is fixedly connected to the top of the reaction tank 5. An output tube 9 is fixedly connected to the bottom of the reaction tank 5;

[0035] Specifically, when the staff needs to take a sample of the chemical materials inside the reaction tank 5 during the chemical production process, first, the cylinder 10 starts to drive the movable block 11 to move backward in the sampling pipe 12. As the movable block 11 moves, the chemical materials inside the reaction tank 5 are under pressure and start to flow along the fixed head 19. The fixed head 19, with its specific shape and structure, provides a stable channel for the flow of the chemical materials. The chemical materials then pass through the quick connector 14. The quick connector 14, with its tight connection and good sealing performance, ensures that the chemical materials will not leak during the flow process. The chemical materials finally flow into the sampling pipe 12 and enter the sampling bottle 13. The sampling pipe 12 and the sampling bottle 13 are usually made of corrosion-resistant and high-temperature-resistant materials, which can withstand the characteristics of the chemical materials. When the sampling is completed, the staff can gently push the movable ring 20 by hand. Under the push of the staff, the movable ring 20 starts to move. The movement of the movable ring 20 releases the original limit on the movable bead 21. After the movable bead 21 loses the limit, its position changes. Further, the limit on the quick connector 14 is also released. At the same time, the conical heads 18 that were originally pressed against each other inside the fixed head 19 and the quick connector 14 also lose the pressing force. The first spring 16 and the telescopic column 17 fixed to the fixed orifice plate 15 behind them start to recover and push out the conical head 18, closing the internal pipeline of the fixed head 19 and the quick connector 14 to ensure that the chemical materials will not leak. After the limit on the quick connector 14 is released, it becomes freely movable. At this time, the staff can easily pull out the quick connector 14 from the fixed head 19. In this way, the staff can quickly remove the sampling device. This process is simple, convenient, and fast, greatly improving the efficiency of the sampling work and reducing the operation difficulty and labor intensity of the staff.

[0036] Refer to Figure 5 - Figure 6

[0037] On the outer wall of the reaction tank 5, there is a fixed connection with an annular arm 4. On the side wall of the annular arm 4, there is a fixed connection with a support arm 2. At the bottom of the support arm 2, there is a fixed connection with a bottom plate 1. At the bottom of the bottom plate 1, there is a fixed connection with column legs 3. Inside the bottom plate 1, there is a fixed connection with a motor box 25. On the inner wall of the motor box 25, there is a fixed connection with a second motor 26. The output end of the second motor 26 is fixedly connected with a worm 27. The inner wall of the motor box 25 is rotatably connected with a worm gear 31. The worm 27 meshes with the worm gear 31. On the side wall of the worm gear 31, there is a fixed connection with a gear 28. On the side wall of the gear 28, there is a rack 29. The rack 29 meshes with the gear 28. The rack 29 is slidably connected inside the motor box 25. One end of the rack 29 is fixedly connected with a wheel 30;Specifically, after using the reaction tank 5, when it is necessary to clean its interior, first start the second motor 26. With the stable operation of the second motor 26, the worm 27 connected thereto is driven to rotate synchronously. The worm 27 transmits power to the worm gear 31. Driven by the worm 27, the worm gear 31 starts to rotate slowly and drives the gear 28 connected thereto to rotate. Driven by the worm gear 31, the rack 29 that cooperates with it starts to move downward. At the same time as the rack 29 moves, the wheel 30 is also driven to move. Driven by the rack 29, the wheel 30 gradually extends from its original storage position. As the wheel 30 extends completely, it also jacks up the entire device. At this time, the staff can easily push the entire device and, with the flexible rolling of the wheel 30, move the device smoothly to the designated cleaning area. In this area, the staff can more conveniently carry out a comprehensive and in-depth cleaning of the reaction tank 5 to ensure that the reaction tank 5 can maintain a good state during the next use and provide a strong guarantee for the smooth progress of chemical production.

[0038] Working principle: When the staff needs to take a sample of the chemical materials inside the reaction tank 5, first the air cylinder 10 drives the movable block 11 to move. As the movable block 11 moves, the chemical materials inside the reaction tank 5 will flow into the sampling tube 12 along the fixed head 19 and the quick connector 14 and finally flow into the sampling bottle 13. After the sampling is completed, the staff can manually push the movable ring 20 to move. The movement of the movable ring 20 releases the limit on the movable bead 21 and further releases the limit on the quick connector 14, enabling the quick connector 14 to be pulled out from the fixed head 19. In this way, the staff can quickly remove the sampling device. When it is necessary to clean the inside of the reaction tank 5 after use, the second motor 26 rotates to drive the worm 27, and then the worm 27 drives the worm gear 31 to rotate. The worm gear 31 drives the gear 28 to rotate. The rotation of the gear 28 causes the rack 29 to start moving and drives the movement of the wheel 30. As the wheel 30 extends, the staff can easily push the entire device and move the device to the designated cleaning area.

[0039] 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 on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
