[0002] The general understanding of reactor sealing is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are achieved. Reactor seals are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, and food, and are pressure vessels used to complete processes such as vulcanization, nitrification, hydrogenation, alkylation, polymerization, and condensation.

[0003] Generally, a reactor is sealed by fixing two groups of flange plates with threads. However, the internal pressure of the reactor is generally relatively high. During the use of the reactor, the internal pressure increases. Since the bolts are in a high-pressure environment for a long time, the bolts and nuts will become loose, resulting in a gap between the two groups of flange plates. The gas inside the reactor will flow out through the gap, resulting in unstable internal pressure of the reactor and affecting the quality of the internal products. Therefore, those skilled in the art have provided a sealing device for a reactor to solve the problems raised in the above background art. Utility Model Content

Detailed implementation manners

[0022] The following further Figures 1-4 describes the present application in detail.

[0023] The embodiment of the present application discloses a sealing device for a reactor. Referring to Figures 1-4 , a sealing device for a reactor includes a reactor body 1, a threaded ejector rod 6 and a sealing assembly 8. A cover plate 2 is arranged above the reactor body 1. Sealing rings 3 are arranged around the cover plate 2 and the reactor body 1. A threaded rod 4 is arranged above the cover plate 2. A plurality of threaded rods 4 are arranged at equal intervals. One end of each of the plurality of threaded rods 4 penetrates through the cover plate 2 and the reactor body 1. A first bolt 41 is arranged on the surface of the threaded rod 4. The first bolt 41 is arranged below the cover plate 2. A plurality of threaded ejector rods 6 are provided. One end of each of the plurality of threaded ejector rods 6 is fixedly connected to the outer wall of the reactor body 1. A limiting ring 5 is sleeved on the surface of each of the plurality of threaded ejector rods 6. A second bolt 7 is arranged below the limiting ring 5. A plurality of second bolts 7 are provided. The plurality of second bolts 7 are sleeved on the surface of the threaded ejector rod 6. Two sets of sealing assemblies 8 are provided. The two sets of sealing assemblies 8 are located on the surfaces of the reactor body 1 and the cover plate 2. The sealing ring 3 is located inside the sealing assembly 8. Fixing plates 9 are arranged on both sides of the sealing assembly 8;

[0024] In this way, during the implementation process, when the staff needs to seal the reactor body 1, the worker hoists the cover plate 2 above the reactor body 1 to make the flange of the reactor body 1 fit with the cover plate 2. Then the worker sequentially inserts the threaded rods 4 into the reactor body 1 and the cover plate 2. The staff fits the sealing ring 3 on the surfaces of the reactor body 1 and the cover plate 2, and then covers the sealing assembly 8 on the surface of the sealing ring 3 to increase the fitting tightness between the sealing ring 3 and the reactor body 1 and the cover plate 2;

[0025] After the two sets of sealing components 8 are fitted, the sealing components 8 are fixed to the outer wall surfaces of the reactor body 1 and the cover plate 2 through the two sets of fixing plates 9. Then, the worker rotates the first bolt 41. During the rotation of the first bolt 41, the reactor body 1 and the cover plate 2 will be squeezed. When the sealing between the reactor body 1 and the cover plate 2 is completed, the worker inserts the limiting ring 5 under the threaded rod 4 and the threaded ejector rod 6, and then threadedly sleeved the second bolt 7 on the surface of the threaded ejector rod 6. Rotate the second bolt 7 to fit the limiting ring 5 with the lower part of the first bolt 41 to limit the first bolt 41. Such a design increases the structural stability of the threaded rod 4 by limiting and squeezing the first bolt 41, and seals the gap between the reactor body 1 and the cover plate 2 through the sealing ring 3 and the sealing components 8, reducing the leakage of gas in the reactor body 1 and increasing safety.

[0026] One end of the threaded ejector rod 6 extends upward, and one end of the threaded ejector rod 6 is fixedly connected to the outer wall of the reactor body 1. The second bolt 7 is threadedly sleeved on the surface of the threaded ejector rod 6. The threaded ejector rod 6 is located below the flange of the reactor body 1. When the limiting ring 5 is inserted outside the threaded rod 4 and the threaded ejector rod 6, the limiting ring 5 will slide along the outer wall of the threaded ejector rod 6 to squeeze the first bolt 41, increasing the structural stability of the first bolt 41.

[0027] Preferably, the sealing component 8 includes a first baffle 81 attached to the outer wall of the sealing ring 3. A second baffle 82 is slidably abutted against the inner wall of the first baffle 81. Arc-shaped plates 83 are fixedly connected to the sides of the first baffle 81 and the second baffle 82 that are away from each other. The sides of the two arc-shaped plates 83 that are close to each other are respectively attached to the outer walls of the reactor body 1 and the cover plate 2;

[0028] The first baffle 81 and the second baffle 82 will fix the sealing ring 3, and the sealing ring 3 seals the gap between the reactor body 1 and the cover plate 2. When the distance between the reactor body 1 and the cover plate 2 changes, through the sliding of the first baffle 81 and the second baffle 82, the outer walls of the arc-shaped plates 83 are attached to the reactor body 1 and the cover plate 2, increasing the sealing stability of the sealing ring 3 for the reactor body 1 and the cover plate 2.

[0029] Specifically, an arc-shaped groove 831 is formed in the inner wall of the arc-shaped plate 83. The threaded rod 4 and the first bolt 41 are both located inside the arc-shaped groove 831 and are attached to the outer wall of the arc-shaped plate 83. The arc-shaped groove 831 is located on one side of the first bolt 41. The nut of the first bolt 41 and the first bolt 41 squeeze and limit the arc-shaped plate 83, making the arc-shaped plate 83 closely attached to the outer walls of the reactor body 1 and the cover plate 2, reducing the shaking of the arc-shaped plate 83, and increasing the installation stability of the sealing component 8.

[0030] More specifically, a slider 821 is fixedly connected to the outer wall of the second baffle 82. A plurality of sliders 821 are equidistantly arranged. The plurality of sliders 821 slide inside the first baffle 81. One side of one of the sliders 821 is fixedly connected to a benchmark 822. One end of the benchmark 822 penetrates through the first baffle 81 and extends outward;

[0031] The outer wall of the second baffle 82 slides closely against the inner wall of the first baffle 81. The slider 821 on the outer wall of the second baffle 82 is inserted into the first baffle 81, which increases the sliding stability of the first baffle 81 and the second baffle 82. A disc is fixed to the end of the benchmark 822 that penetrates through the first baffle 81, which can facilitate the staff to observe the depth of the slider 821 inserted into the first baffle 81.

[0032] Further, during the implementation process, one side of the two sets of fixing plates 9 is mutually attached. A fixing rod 91 is fixedly inserted into the fixing plates 9. Threaded rings are sleeved on the surfaces of both ends of the fixing rod 91. The fixing rod 91 is used to clamp the two sets of fixing plates 9. When the two sets of fixing plates 9 are attached, the first baffle 81 and the second baffle 82 will closely adhere to the outer walls of the sealing ring 3, the reaction kettle body 1, and the cover plate 2, which increases the structural stability of the installation of the first baffle 81 and the second baffle 82.

[0033] The implementation principle of the sealing device of a reaction kettle in the embodiment of the present application is as follows: When the staff needs to seal the reaction kettle body 1, the worker hoists the cover plate 2 above the reaction kettle body 1 to make the flange of the reaction kettle body 1 fit with the cover plate 2. Then the worker sequentially inserts the threaded rod 4 into the reaction kettle body 1 and the cover plate 2. The staff fits the sealing ring 3 on the surfaces of the reaction kettle body 1 and the cover plate 2, and then covers the sealing assembly 8 on the surface of the sealing ring 3 to increase the fitting tightness between the sealing ring 3, the reaction kettle body 1, and the cover plate 2. After the two sets of sealing assemblies 8 are attached, the sealing assembly 8 is fixed to the outer wall surfaces of the reaction kettle body 1 and the cover plate 2 through the two sets of fixing plates 9. Then the worker rotates the first bolt 41. During the rotation of the first bolt 41, the reaction kettle body 1 and the cover plate 2 will be squeezed. When the reaction kettle body 1 and the cover plate 2 are sealed, the worker inserts the limit ring 5 below the threaded rod 4 and the threaded top rod 6, and then threadedly sleeves the second bolt 7 on the surface of the threaded top rod 6. Rotate the second bolt 7 to make the limit ring 5 fit with the lower part of the first bolt 41 to limit the first bolt 41. Such a design increases the structural stability of the threaded rod 4 through the limit extrusion of the first bolt 41, seals the gap between the reaction kettle body 1 and the cover plate 2 through the sealing ring 3 and the sealing assembly 8, reduces the leakage of gas in the reaction kettle body 1, and increases safety.
