Description

Technical Field

[0001] The invention relates to the technical field of polymerization reactors, in particular to a carboxyl nitrile latex polymerization reactor with precise temperature control. Background Art

[0002] The precise temperature-controlled carboxy nitrile latex polymerization reactor, as a key equipment in the field of polymer material preparation, is specially designed for efficient and stable polymerization of carboxy nitrile latex. Its core design highlight lies in its excellent temperature control capability. Through the advanced temperature control system, it can achieve precise temperature control during the reaction process to ensure that the polymerization reaction is carried out within the optimal temperature range, thereby greatly improving the reaction efficiency and ensuring the stability and consistency of product quality. Considering the large volume and complex internal environment of the reactor, in order to accurately obtain and monitor the real-time status of the reactants inside it, it is usually necessary to install at least two sampling and detection devices at different positions of the reactor. These sampling and detection devices are like the reactor's "Eyes" can capture the changes of key parameters in the reaction process and provide valuable experimental data for scientific researchers to guide the optimization and adjustment of the reaction. However, in traditional sampling and detection practices, these sampling and detection devices are often designed as independently operated systems, each operating independently and lacking unified management and coordination. This practice not only leads to redundant configuration and waste of resources, but also introduces potential detection errors due to the inherent differences between the sensors of each device. Such errors may mislead scientific researchers' judgment on the reaction process, affect the accuracy and reliability of the experimental results, and may even have an adverse effect on the progress and results of the entire R&D project. For this reason, we propose a carboxyl nitrile latex polymerization reactor with precise temperature control. Summary of the invention

When the lever 4 is deflected, the deflection plate 69 is driven to deflect, and then the connecting rod 72 is driven to move, thereby driving the pulling rod 68 to move and pull the tension spring 66.

[0049] The connecting member 64 includes a hollow cylinder 1 73 fixedly connected to the U-shaped frame 55, a hollow cylinder 2 74 fixedly connected to the H-shaped frame 53, a latch 75 slidably connected inside the hollow cylinder 1 73, and one end of the latch 75 is located inside the hollow cylinder 2 74 to lock the U-shaped frame 55 and the H-shaped frame 53;

[0050] A rectangular plate 76 is fixedly connected to the mounting frame 56, one end of the latch 75 is fixedly connected to a cylindrical protrusion 77, a guide groove 78 is provided on the rectangular plate 76, one end of the cylindrical protrusion 77 is located in the guide groove 78, and a locking member 79 is provided between the rectangular block 65 and the U-shaped frame 55.

[0051] The guide groove member 78 includes a straight groove 81 formed on the rectangular plate 76. One end of the cylindrical protrusion 77 is located in the straight groove 81 and is slidably connected to the inner wall thereof. When the U-shaped frame 55 is moved, the cylindrical protrusion 77 slides along the straight groove 81 to stably connect the U-shaped frame 55 and the H-shaped frame 53.

[0052] The rectangular plate 76 is provided with an inclined slide groove 82 which is connected to the straight slide groove 1 81 . When the U-shaped frame 55 is moved, the cylindrical protrusion 77 is driven to slide along the inclined slide groove 82 to drive the latch 75 to disengage from the hollow cylinder 2 74 .

[0053] The rectangular plate 76 is provided with a second straight slide groove 83 connected to the oblique slide groove 82 , so that the cylindrical protrusion 77 is driven to slide along the second straight slide groove 83 during the subsequent movement of the U-shaped frame 55 to stabilize the state of the latch 75 being separated from the second hollow cylinder 74 .

[0054] The locking member 79 includes two sliding columns 84 symmetrically slidably connected in the rectangular block 65, a spring 85 is fixedly connected between the two sliding columns 84, and a sliding column 86 is slidably connected in the hollow cylinder 74. When the latch 75 is inserted into the hollow cylinder 74, the sliding column 86 is pushed to move and push the sliding column 84 out of the hollow cylinder 74, and at the same time, the spring 85 is compressed to provide it with self-restoring elastic force.

[0055] Specifically, when the carboxyl nitrile latex reacts in the reactor, the initial step is to mix various raw materials. After the mixing is completed, additives will be further added to allow the reaction to proceed. As the reaction proceeds, the viscosity of the reactants will gradually increase. When the device is in use, the electric push rod 57 is started to drive the U-shaped frame 55 and the H-shaped frame 53 to move synchronously (at this time, because the cylindrical protrusion 77 is located in the straight slide groove 1 81, and the latch 75 is located in the hollow cylindrical second 74 on the H-shaped plate to connect the U-shaped frame 55 and the H-shaped frame 53 into a whole, at this time, one end of the tension sensor 63 is fixed to the U-shaped frame 55 The lever 4 is fixedly connected, and the other end is fixedly connected to the pull rod 68 through the tension spring 66), thereby driving the lever 4 to move, thereby driving the two pistons 3 to move to extract the reactants in the reactor body 1. At this time, two situations may occur. In the first situation, when the upper and lower layers of the reaction substances in the reactor body 1 are not mixed well, or the reaction is uneven, the viscosity of the upper and lower layers of the reaction substances in the reactor is different. Therefore, when the lever 4 drives the two pistons 3 to move, the resistance they encounter is also different, which causes the lever 4 to deflect due to the uneven force at both ends, so as to drive the deflection plate 69 to deflect and pull the connecting rod 72, thereby driving the pull rod 68 to move and pull the tension spring 66, so as to The tension sensor 63 is pulled, and then a signal is sent through the tension sensor 63 to control the electric push rod 57 to reset and push out the reactants in the syringe 2 (indicating that the reaction progress of the reactants in the reactor body 1 is different in different areas, or the mixing is not in place), and at the same time, it indicates that the materials in the reactor body 1 are unevenly mixed or react unevenly, and the reaction should continue and be fully stirred. In the second case, when the viscosity of the upper and lower layers of the reactor is the same, the resistance encountered when the lever 4 drives the two pistons 3 to move is also the same, and then the lever 4 will not deflect. At this time, the tension sensor 63 is not subjected to force, and then the electric push rod 5 is activated. 7 continues to pull, and at the same time drives the cylindrical protrusion 77 to slide along the inclined slide groove 82, thereby driving the latch 75 to pull out the hollow cylinder 2 74, and at the same time the spring 85 resets to drive the sliding column 84 to insert into the hollow cylinder 2 74, thereby fixing one end of the tension sensor 63 to the H-shaped frame 53, and at the same time disconnecting the H-shaped frame 53 from the U-shaped frame 55. At this time, the two ends of the tension sensor 63 are respectively fixed to the U-shaped frame 55, and the other end is fixed to the H-shaped frame 53, so that the tension sensor 63 is used to test the resistance of the two pistons 3, so as to detect the viscosity of the reactants, and then monitor the reaction process of the reactants;

[0056] The device starts the electric push rod 57 and uses the lever 4 to drive the two pistons 3 to move and extract the reactants in the reactor body 1, and then judges the reaction status of the reactants by the movement of the two pistons 3, so that multiple detection devices are operated in a coordinated manner, which is more resource-saving. At the same time, when the mixing degree of the upper and lower layers of the reactants in the reactor body 1 is detected, and when the viscosity of the reactants is detected, the same tension sensor 63 is used, which is more resource-saving and avoids the inherent differences that may exist between sensors, thereby introducing potential detection errors.

[0057] Example 2: Please refer to Figure 1-7 , the present invention provides a technical solution: Example 2 is optimized on the basis of Example 1;

[0058] The two ends of the tension sensor 63 are detachably connected to the U-shaped frame 55 and the rectangular block 65 respectively. The detachable design of the tension sensor 63 facilitates subsequent debugging, disassembly and replacement thereof.
