[0002] 3-Methyl-3-carboxy-1-oxetane is an important organic synthesis intermediate with wide applications in pharmaceuticals, pesticides, and polymer materials. With the rapid development of related industries, the demand for this compound continues to rise. Continuous production equipment for 3-methyl-3-carboxy-1-oxetane avoids the frequent feeding, heating, cooling, and discharging operations required in intermittent production, significantly shortening the production cycle and better matching the large market demand for this compound.

[0003] Currently, the stirring of 3-methyl-3-carboxy-1-oxecyclobutane feedstock is usually achieved by a stirring mechanism with a fixed height. However, in actual use, a stirring mechanism with a fixed height will create a large number of dead zones, where the material is difficult to flow, resulting in the inability to achieve uniform mixing of feedstock, catalyst and product.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Reference Figures 1-3An embodiment of this utility model provides a continuous production apparatus for 3-methyl-3-carboxy-1-oxetane, comprising a base plate 1, a stirring cylinder 2 fixedly connected to the upper surface of the base plate 1, a support column 3 fixedly connected to the upper surface of the stirring cylinder 2, a grooved column 8 fixedly connected to the inner top wall of the support column 3, a motor 4 fixedly connected to the upper surface of the support column 3, a rotating plate 5 fixedly provided at the output end of the motor 4, a sliding column 6 slidably connected to the outer wall of the rotating plate 5, a sliding ball 7 fixedly connected to the outer wall of the sliding column 6, the outer wall of the sliding ball 7 slidably connected to the inner wall of the grooved column 8, a stirring rod 9 fixedly connected to the lower surface of the sliding column 6, and a sealing assembly provided inside the stirring cylinder 2 for sealing the stirring device; Specifically, the base plate 1 supports and fixes the mixing drum 2, which in turn supports and fixes the support column 3. The support column 3 then supports and fixes the motor 4, ensuring the stability of the motor 4 during operation. When the motor 4 starts, it drives the rotating plate 5 at the output end to rotate, causing the sliding column 6 to rotate synchronously. The outer wall of the rotating plate 5 is rectangular, and the inner wall of the sliding column 6 is also rectangular, ensuring that the rotation of the sliding plate 5 does not affect the vertical movement of the sliding column 6. The sliding column 6 supports and fixes the sliding ball 7. When the sliding column 6 rotates... The sliding ball 7 rotates synchronously, and the support column 3 supports and fixes the groove column 8. The inner wall of the groove column 8 has an arc-shaped groove, so when the sliding ball 7 rotates, it slides in the groove of the groove column 8 and rotates and rises. The sliding column 6 supports and fixes the stirring rod 9, so when the sliding column 6 rotates, it drives the stirring rod 9 to rotate and rise to stir the raw materials. The stirring rod 9 moves up and down with the stirring action, which can stir different liquid levels and areas in real time, break the dead zone of fixed stirring, and make the raw materials, catalyst and products fully mixed in the device, so as to ensure the stability of continuous production and the uniformity of products.

[0020] Reference Figure 1 and Figure 2 The enclosed assembly includes a rotating shaft 10, the outer wall of which is fixedly connected to the inside of the mixing drum 2, and a cover plate 11 is rotatably connected to the outer wall of the rotating shaft 10. The lower surface of the cover plate 11 is in contact with the upper surface of the mixing drum 2. Specifically, the mixing drum 2 supports and fixes the rotating shaft 10. Lifting the cover plate 11 and rotating it on the outer wall of the rotating shaft 10 can stir the material inside the device. Closing the cover plate 11 can seal the device and prevent the raw materials from splashing out during the mixing process.

[0021] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6One end of a transmission pipe 12 is fixedly connected to the outer wall of the stirring drum 2, and the other end of the transmission pipe 12 is fixedly connected to a steaming drum 13. A distiller 14 is fixedly connected to the upper surface of the steaming drum 13, and a support 15 is fixedly connected to the lower surface of the steaming drum 13. The lower surface of the support 15 is fixedly connected to the upper surface of the base plate 1. A support plate 25 is fixedly connected to the inner wall of the support 15, and a support plate 23 is fixedly connected to the lower surface of the support plate 25. A hydraulic rod 16 is fixedly connected inside the support 15, and a pusher is fixedly installed at the output end of the hydraulic rod 16. The outer wall of the moving block 17 is rotatably connected to a baffle plate 19. The lower surface of the baffle plate 19 is in contact with the surface of the support plate 23. The outer wall of the moving block 17 is fixedly connected to a discharge cylinder 18. The lower surface of the discharge cylinder 18 is in contact with the upper surface of the baffle plate 19. The upper surface of the discharge cylinder 18 is fixedly connected to a sliding plate 20. The outer wall of the sliding plate 20 is slidably connected to the inner wall of the support plate 25. The upper surface of the sliding plate 20 is slidably connected to a nozzle 21. The upper surface of the nozzle 21 is fixedly connected to the inner top wall of the bracket 15. Specifically, the stirring drum 2 supports and fixes the transmission pipe 12, and the distillation tank 13 supports and fixes the transmission pipe 12. The material mixed inside the stirring drum 2 is transported to the inside of the distillation tank 13 through the transmission pipe 12. The distillation tank 13 supports and fixes the still 14. The still 14 is started to distill the material inside the distillation tank 13. The support 15 supports and fixes the distillation tank 13. The distilled material inside the distillation tank 13 is transported through the nozzle 21. The material enters the discharge cylinder 18 through the sliding plate 20 and is received by the baffle plate 19 to prevent it from flowing out. The support 15 supports and fixes the hydraulic rod 16, the support plate 25, and the support plate 25. The function of the hydraulic rod 16 is to push the push block 17 at the output end when the hydraulic rod 16 is activated. The push block 17 supports and fixes the discharge cylinder 18, so that the push block 17 pushes the discharge cylinder 18 synchronously when it moves. The discharge cylinder 18 supports and fixes the sliding plate 20. When the discharge cylinder 18 moves, it slides on the inner wall of the support plate 25 through the sliding plate 20. When the discharge cylinder 18 moves to a certain position, the blocking plate 19 on the outer wall of the push block 17 will gradually detach from the support of the support plate 23, thereby realizing quantitative discharge of materials, precise control of the discharge amount, avoiding imbalance of reaction conditions caused by material fluctuations in the preceding and following processes, ensuring the matching of raw material and product ratios, reducing material accumulation or material interruption, improving equipment utilization, and providing core support for the stability and standardization of continuous production.

[0022] Example 2: Reference Figure 7A support cylinder 24 is fixedly connected to the upper surface of the support column 3. A transmission plate 26 is rotatably connected to the inner wall of the support cylinder 24. The lower surface of the transmission plate 26 is fixedly connected to the upper surface of the rotating plate 5. A handle 22 is rotatably connected to the inside of the transmission plate 26. Specifically, the support column 3 supports and fixes the support cylinder 24, and the rotating plate 5 supports and fixes the transmission plate 26. Cranking the handle 22 drives the transmission plate 26 to rotate on the inner wall of the support cylinder 24, and the support cylinder 24 supports the rotation of the transmission plate 26. When the transmission plate 26 rotates, it drives the rotating plate 5 to rotate synchronously. Thus, the rotating plate 5 drives the stirring component to stir and rise and fall, which can stir different liquid levels and areas in real time, break the dead zone of fixed stirring, and make the raw materials, catalysts and products fully mixed in the device, so as to ensure the stability of continuous production and the uniformity of products.

[0023] Working principle: When the device is needed, the cover plate 11 is lifted and the inside of the stirring drum 2 is rotated through the rotating shaft 10. The raw materials are poured into the inside of the stirring drum 2. The motor 4 on the upper surface of the support column 3 is started to rotate the rotating plate 5 at the output end. When the rotating plate 5 rotates, the sliding ball 7 rotates synchronously through the sliding column 6. When the sliding ball 7 rotates, it slides in the groove on the inner wall of the groove column 8, so that the sliding ball 7 stirs and lifts the stirring rod 9 synchronously through the sliding column 6. It can stir different liquid levels and areas in real time, break the dead corner of fixed stirring, and make the raw materials, catalysts and products fully mixed in the device, so as to ensure the stability of continuous production and the uniformity of products. After the raw materials are mixed, the material inside the mixing tank 2 is transferred to the steaming tank 13 through the transfer pipe 12. The distiller 14 is started to distill the material inside the steaming tank 13. The distilled material enters the discharge cylinder 18 through the nozzle 21. The hydraulic rod 16 is started to push the discharge cylinder 18 through the push block 17 at the output end. When the discharge cylinder 18 moves, it slides on the inner wall of the support plate 25 through the sliding plate 20. As it moves, the baffle plate 19 gradually detaches from the surface of the support plate 23, thereby opening the baffle plate 19 and allowing the material inside the discharge cylinder 18 to flow out quantitatively. This precise control of the discharge amount avoids the imbalance of reaction conditions caused by material fluctuations in the preceding and following processes, ensures the matching of raw material and product ratios, reduces material accumulation or material interruption, improves equipment utilization, and provides core support for the stability and standardization of continuous production. In practical use, this continuous production unit for 3-methyl-3-carboxy-1-oxecyclobutane not only achieves material stirring and lifting, but also enables real-time stirring of different liquid levels and areas, breaking the dead zones of fixed stirring. This ensures thorough mixing of raw materials, catalysts, and products within the unit, guaranteeing the stability and product uniformity of continuous production. Furthermore, it allows for precise control of the discharge rate, preventing imbalances in reaction conditions caused by material fluctuations in upstream and downstream processes. This ensures a matching ratio of raw materials to products, reduces material accumulation or supply interruptions, and improves equipment utilization, providing core support for the stability and standardization of continuous production.
