Description

Technical Field

[0001] This utility model relates to the field of polymerization reactor technology, specifically a polymerization reactor equipped with a torque sensor. Background Technology

[0002] A polymerization reactor is a piece of equipment used for chemical reactions, polymerization reactions, or other chemical processes. It is widely used in industries such as chemical, pharmaceutical, food, and plastics. Polymerization reactors are commonly used for polymer polymerization reactions, such as monomer polymerization. In this process, the polymerization reactor provides appropriate temperature, pressure, and stirring conditions to promote the combination of monomer molecules to form polymers.

[0003] In existing technologies, it is impossible to monitor the torque changes of the agitator in real time during polymerization reactor stirring operations. Especially during the polymerization reaction, the increase in material viscosity as the reaction progresses directly affects the load on the agitator. When the load on the agitator exceeds the design range, it may cause equipment overload, leading to mechanical failure or reduced reaction efficiency, thereby affecting the stability and reliability of the overall production process.

[0004] Therefore, those skilled in the art have provided a polymerization reactor with a torque sensor to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1 , 2 As shown in Figure 3, this embodiment of the present invention provides a polymerization reactor with a torque sensor, including a polymerization reactor 1, a connecting mechanism 5, a snap-fit ​​fixing mechanism 6, and a torque sensor 4. The upper end of the polymerization reactor 1 is fixedly connected to a servo motor 2, and a stirring rod 3 is rotatably connected through one side of the polymerization reactor 1. The upper and lower ends of the torque sensor 4 are both provided with connecting mechanisms 5, and the polymerization reactor 1 and the torque sensor 4 are provided with snap-fit ​​fixing mechanisms 6. The connecting mechanism 5 is used to fix the torque sensor 4 to the output end of the servo motor 2 and the stirring rod 3, and the snap-fit ​​fixing mechanism 6 is used to fix the torque sensor 4.

[0026] In this embodiment, when installing the torque sensor 4, the position between the servo motor 2 and the stirring rod 3 in the polymerization reactor 1 is opened. The torque sensor 4 is first installed and fixed on the polymerization reactor 1 by the snap-fit ​​fixing mechanism 6. Then, the snap-fit ​​fixing mechanisms 6 at both ends of the torque sensor 4 are fixedly connected to the output end of the servo motor 2 and the stirring rod 3, respectively. Thus, the torque sensor 4 can detect the load change of the stirrer in real time, avoid overload of the stirrer, and reduce mechanical failures and damage to the equipment.

[0027] like Figure 2 , 3 As shown in Figure 5, optionally, the connecting mechanism 5 includes a limiting block unit and a connecting block unit. The connecting block unit facilitates the connection of the stirring rod 3 and the servo motor 2 to the limiting block unit, and the limiting block unit is used to fix the connecting block unit.

[0028] In this embodiment, the connecting block unit is first fixedly installed on the stirring rod 3 and the output end of the servo motor 2 near the torque sensor 4, and then connected to the limiting block units at both ends of the torque sensor 4, so that the output end of the servo motor 2 drives the rotating rod in the torque sensor 4 to rotate, and the torque sensor 4 detects the torque of the rotating rod.

[0029] like Figure 3 and 4 As shown, optionally, the limiting block unit includes a limiting block 51, a first spring 52, a threaded groove 53, and a locking unit. The two ends of the torque sensor 4 are respectively limited and slidably connected to the limiting block 51. The two sets of limiting blocks 51 are respectively fixedly connected to the two ends of the torque sensor 4 with the first spring 52. The locking unit is used to lock the position between the two ends of the torque sensor 4 and the two sets of limiting blocks 51.

[0030] In this embodiment, the limiting blocks 51 at both ends of the torque sensor 4 slide on the rotating rod of the torque sensor 4. When it is necessary to connect with the connecting block unit, by opening the locking unit, the first spring 52 between the limiting block 51 and the rotating rod of the torque sensor 4 releases its elastic force, thereby causing the first spring 52 to drive the limiting block 51 to slide outward on the rotating rod of the torque sensor 4, so that the limiting block 51 and the connecting block unit are engaged, thereby completing the connection.

[0031] like Figure 4 As shown, optionally, the locking unit includes a threaded groove 53, a first bolt 54, and a second spring 55. One side of each of the two sets of limiting blocks 51 is threadedly connected to the first bolt 54. The two ends of the torque sensor 4 are respectively provided with threaded grooves 53 at positions corresponding to the two sets of first bolts 54. The two sets of threaded grooves 53 are threadedly connected to the two sets of first bolts 54. A second spring 55 is sleeved on the outside of each of the two sets of first bolts 54. One end of each of the two sets of second springs 55 is fixedly connected to the first bolt 54, and the other end of each of the two sets of second springs 55 is fixedly connected to the two sets of limiting blocks 51.

[0032] In this embodiment, when the limiting block 51 is released, the first bolt 54 is rotated to loosen the threaded groove 53 on the rotating rod of the torque sensor 4, thereby releasing the elastic force of the first spring 52. When the limiting block 51 is locked, the first bolt 54 is pushed upward by hand, and the first bolt 54 drives the limiting block 51 to compress the first spring 52. When the first bolt 54 and the threaded groove 53 are aligned, the first bolt 54 is rotated to fix the thread of the first bolt 54 in the threaded groove 53, so that the limiting block 51 can be flexibly connected or released as needed by the connecting unit.

[0033] like Figure 5 As shown, optionally, the connecting block unit includes a connecting block 56, a second bolt 57, and a limiting groove 58. The connecting block 56 is slidably sleeved on the outer side of one end of the stirring rod 3 and the output end of the servo motor 2. The limiting groove 58 is opened on the side of the two sets of connecting blocks 56 near the limiting block 51. The two sets of connecting blocks 56 are respectively threadedly fixed to the stirring rod 3 and the output end of the servo motor 2 by the second bolt 57.

[0034] In this embodiment, by fitting the connecting block 56 onto the output end of the stirring rod 3 or the servo motor 2, and then fixing the connecting block 56 with the thread by the second bolt 57, the limiting unit can be directly inserted into the limiting groove 58 inside the connecting block 56 for connection, which facilitates the connection between the limiting block unit and the connecting block unit.

[0035] like Figure 2 and 3As shown, optionally, the snap-fit ​​fixing mechanism 6 includes a snap-fit ​​base 61, a snap-fit ​​block 65, and a clamping unit. The snap-fit ​​base 61 is fixedly connected to the polymerization reactor 1 near the torque sensor 4. The snap-fit ​​block 65 is fixedly connected to the torque sensor 4 at a corresponding position to the snap-fit ​​base 61. The snap-fit ​​base 61 and the snap-fit ​​block 65 cooperate with each other. The clamping unit is used to lock the snap-fit ​​base 61 and the snap-fit ​​block 65.

[0036] In this embodiment, the torque sensor 4 is installed by aligning the snap-fit ​​block 65 on one side of the torque sensor 4 with the snap-fit ​​slot in the snap-fit ​​base 61, and then the snap-fit ​​block 65 installed in the snap-fit ​​base 61 is fixed by the snap-fit ​​unit, so that the torque sensor 4 is stably fixed.

[0037] like Figure 3 As shown, optionally, the clamping unit includes an L-shaped rod 63 and a third spring 64. The L-shaped rod 63 is slidably connected through one side of the clamping base 61. The third spring 64 is sleeved on the outside of the L-shaped rod 63. One end of the third spring 64 is fixedly connected to the L-shaped rod 63, and the other end of the third spring 64 is fixedly connected to the clamping base 61.

[0038] In this embodiment, the side of the L-shaped rod 63 near the mounting clip 65 is inclined. When the clip 65 is installed in the mounting base 61, the clip 65 and the inclined side of the L-shaped rod 63 come into contact. The L-shaped rod 63 is automatically inserted into the clip 65 by the third spring 64. When the clip 65 is released, the L-shaped rod 63 is pulled outward to release the clip 65, so that the torque sensor 4 is fixed in the mounting base 61.

[0039] like Figure 1 As shown, optionally, a fixed mounting bracket 7 is fixedly connected to the outside of the polymerization reactor 1.

[0040] In this embodiment, the fixed mounting bracket 7 facilitates the fixed installation of the polymerization reactor 1.

[0041] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
