[0027] Figure 1 This is a schematic diagram of the structure of a reaction kettle sealing cover provided in an embodiment of the present application. Figure 2 A partially enlarged view of a groove of a sealing cover of a reaction kettle provided in an embodiment of the present application.

[0028] Please also read Figure 1 and Figure 2The embodiment of the first aspect of the present application provides a reactor sealing cover, which includes: a main body 100, which is annular, and the main body 100 includes a first end 101 and a second end 102 that are relatively arranged along the axis of the main body 100, and the end surface of the first end 101 away from the second end 102 is recessed to form a groove 103; an end cover 200, which is covered on the first end 101 and rotatably connected to one side of the first end 101; a sealing part 104, which is located in the groove 103 so that the main body 100 and the end cover 200 are sealed and connected through the sealing part 104.

[0029] In the embodiments provided in this application, Figure 1 As shown, the reactor sealing cover comprises: a main body 100 in an annular shape, and the main body 100 is sleeved on the reactor to seal the reactor. The main body 100 comprises a first end 101 and a second end 102 which are arranged oppositely along the axis of the main body 100, wherein the end cover 200 is covered on the first end 101 and rotatably connected to one side of the first end 101. The end surface of the first end 101 away from the second end 102 is concave to form a groove 103, and the groove 103 is used to place the sealing part 104, so that the sealing part 104 fills the gap between the end cover 200 and the first end 101 of the main body 100, and the main body 100 and the end cover 200 are sealed and connected through the sealing part 104, thereby reducing the leakage of corrosive and explosive unstable gas generated in the reactor during the production process, reducing resource waste and protecting the environment.

[0030] Optionally, the reactor is a reaction equipment that can realize the heating, evaporation, cooling and low-speed mixing functions required by the process. It is a pressure vessel used to complete process such as sulfidation, nitration, hydrogenation, verticalization, polymerization, condensation, etc. The reactor sealing cover is used to seal the reactor, and the end cover 200 is the reactor cover.

[0031] Optionally, the sealing part 104 can be a fluororubber sealing gasket, which has good wear resistance, excellent heat resistance, is not easily corroded by chemicals, and has elasticity. The sealing part 104 is located in the groove 103, and the groove 103 positions the sealing part 104 and facilitates the frequent opening and closing of the end cover 200 during the use of the reactor sealing cover, effectively preventing the sealing part 104 from being squeezed out and losing the sealing function.

[0032] Optionally, in a closed condition, at a certain temperature, the pressure of steam in equilibrium with a solid or liquid is called saturated vapor pressure. The condition to ensure that the gas in the reactor does not leak is that the internal gas pressure is greater than the saturated vapor pressure. In the embodiment of the present application, the preload force of the sealing portion 104 should be 1.01 times the saturated vapor pressure inside the reactor.

[0033] In some optional embodiments, the width of the groove 103 is 0.7 to 0.8 times the maximum thickness of the sealing portion 104 .

[0034] In these optional embodiments, the width of the groove 103 and the thickness of the sealing portion 104 are both dimensions along the radial direction of the main body 100. The width of the groove 103 is 0.7 to 0.8 times the maximum thickness of the sealing portion 104, that is, the sealing portion 104 is slightly larger than the groove 103, so as to fill the groove 103, so that the gap between the groove 103 and the sealing portion 104 is as small as possible, and the sealing effect is better. It can prevent the sealing portion 104 from being too small to fill the groove 103, and it can also prevent the sealing portion 104 from being too large to be installed in the groove 103.

[0035] Optionally, the width of the groove 103 may be 8 mm, and the thickness of the sealing portion 104 may be 10 mm.

[0036] In some optional embodiments, the ratio of the height of the sealing portion 104 to the depth of the groove 103 is 10:9 to 10:6.

[0037] In these optional embodiments, the height of the sealing portion 104 and the depth of the groove 103 are both dimensions along the axial direction of the main body 100. Since the sealing portion 104 is elastic, the sealing portion 104 can fill the groove 103. However, the elasticity of the sealing portion 104 is limited, wherein the height of the sealing portion 104: the depth of the groove 103 is 10:6 to 10:9. The problem that the portion of the sealing portion 104 protruding axially from the groove 103 of the main body 100 lifts up the end cover 200 when the end cover 200 is closed due to the sealing portion 104 being too high can be reduced, resulting in an unstable fit and prone to displacement and shaking. The problem that the sealing portion 104 cannot fill the gap between the end cover 200 and the first end 101 due to the sealing portion 104 being too short can also be reduced.

[0038] In some optional embodiments, when the end cover 200 is not covered on the first end 101 , the sealing portion 104 includes a protrusion 105 , and the protrusion 105 is protruding from the end surface of the first end 101 away from the second end 102 .

[0039] In these optional embodiments, in order to make the sealing portion 104 fit more closely between the groove 103 and the end cover 200, when the end cover 200 is not covered on the first end 101, the sealing portion 104 further includes a protrusion 105 provided on the end surface of the first end 101 away from the second end 102. When the end cover 200 is covered on the first end 101, since the sealing portion 104 is elastic, the protrusion 105 can be pressed down to fill the gap between the end cover 200 and the first end 101, thereby achieving sealing.

[0040] In some optional embodiments, the height of the protrusion 105 does not exceed 4 mm.

[0041] In these optional embodiments, in order to save materials for the sealing portion 104 and prevent the height of the protrusion 105 from being too high, the end cover 200 cannot be pressed tightly when it is covered on the first end 101, and the protrusion 105 is partially exposed to the outside and in contact with the gas in the reactor, which affects the service life. Therefore, the height of the protrusion 105 may not exceed 4 mm.

[0042] In some optional embodiments, the shape of the groove 103 includes a rectangle or a trapezoid.

[0043] In these optional embodiments, the shape of the groove 103 can be rectangular, that is, the hollowed-out portion of the groove 103 cross section is rectangular. The rectangular groove 103 is simple to manufacture, and the corresponding sealing portion 104 with a rectangular cross section can be better embedded in the groove 103.

[0044] Optionally, when a hollow cylindrical sealing part 104 is used, the shape of the groove 103 can also be a trapezoid, that is, the hollowed-out part of the cross section of the groove 103 can be a trapezoid. The trapezoidal groove 103 can buckle the sealing part 104 and is not easy to fall off.

[0045] In some optional embodiments, the end cover 200 includes a rotating portion 201 disposed relatively to the first end 101 on a side away from the groove 103 , and the end cover 200 is rotatable relative to the rotating portion 201 .

[0046] In these optional embodiments, the end cover 200 is covered on the first end 101 of the main body 100 , and the opening and closing of the end cover 200 can be controlled by the rotating part 201 .

[0047] In some optional embodiments, the reactor sealing cover further includes a limiting portion 202 , which is arranged on the periphery of the first end 101 opposite to the rotating portion 201 , and protrudes from the first end 101 in a direction away from the main body 100 to abut against the end cover 200 .

[0048] In these optional embodiments, the limiting portion 202 is a positioning device in the sealing cover of the reactor. The limiting portion 202 and the rotating portion 201 are arranged on the side of the first end 101 relative to each other, and the limiting portion 202 protrudes from the first end 101 in a direction away from the main body 100 to abut against the end cover 200 to prevent relative displacement between the end cover 200 and the first end 101, which can better fix the end cover 200 and ensure that the end cover 200 will not be misaligned when it is closed.

[0049] In some optional embodiments, the reactor sealing cover further includes a sealing flange 300 , which is located at the second end 102 and protrudes in a direction perpendicular to the axis.

[0050] In these optional embodiments, the sealing flange 300 is located at the second end 102 and protrudes in a direction perpendicular to the axis, and the reactor sealing cover is sealed with the reactor opening by the sealing flange 300. The sealing flange 300 is connected to the reactor body by bolts, has good corrosion resistance and wear resistance, can be repeatedly disassembled and assembled, and has a long service life.

[0051] Optionally, the reactor sealing cover further includes a lock buckle 301 located on the periphery of the main body, the lock buckle 301 includes a base 302 and a ring 303 arranged on the periphery of the main body 100, one end of the ring 303 is connected to the base 302, and the other end is rotatably connected relative to the base 302. The ring 303 is rotated to abut against the end cover 200 to seal the end cover 200. There are multiple lock buckles 301, and the multiple lock buckles 301 are evenly spaced around the periphery of the main body 100 to further seal the end cover 200.

[0052] Optionally, there may be four lock buckles 301 , and the number of lock buckles 301 is not specifically limited as long as the usage requirements can be met.

[0053] Optionally, the second end 102 of the main body 100 further includes a grid 304, the grid 304 includes a side portion arranged around the axis, one end of the side portion is fixedly connected to the main body 100, and the other end of the side portion includes a bottom fixedly connected to the side portion. During use, the grid 304 is used to prevent large objects from falling into the reactor.

[0054] An embodiment of the second aspect of the present application further provides a reaction kettle, comprising the above reaction kettle sealing cover.

[0055] In the embodiment provided in the present application, the reactor includes a reactor sealing cover, which includes a ring-shaped main body 100, which is sleeved on the reactor to seal the reactor.

The end surface of the first end 101 away from the second end 102 is concave to form a groove 103, and the groove 103 is used to place the sealing part 104, so that the sealing part 104 fills the gap between the end cover 200 and the first end 101 of the main body 100, and the main body 100 and the end cover 200 are sealed and connected through the sealing part 104, thereby reducing the leakage of corrosive and explosive unstable gases generated in the reactor during the production process, reducing resource waste and protecting the environment.
