Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of safe production structure of reaction vessels, specifically to a reaction vessel device for safe chemical production. Background Technology
[0002] Reactors are one of the main pieces of equipment in chemical production. Various raw materials are put into the reactor, where they undergo various reactions to produce new materials or products. They are also important production equipment in the chemical, petroleum, and biological industries.
[0003] Because the reaction takes place inside the reactor, the heat and gas generated during the reaction will accumulate inside the reactor. This can easily cause an imbalance in the gas pressure inside and outside the reactor, which can lead to problems with the reactor or even damage and shutdown. Therefore, pressure regulation is necessary to ensure the safe production of the reactor.
[0004] Current pressure regulation directly connects the inside of the reactor to the outside, dissipating the pressure and heat. However, this method also allows outside gases to enter the reactor, affecting the internal temperature. Since temperature changes can affect the reaction effect and even lead to reaction failure, a reactor device for safe chemical production is proposed. Utility Model Content
[0005] In view of the deficiencies in the existing technology, this utility model provides a reaction vessel device for safe chemical production, which improves the safety during production, does not directly connect the inside of the vessel to the outside world, ensures the relative independence of the inside of the vessel, avoids large temperature changes inside the vessel, and ensures automatic regulation of the pressure inside the vessel to prevent pressure imbalance from causing damage to the reaction vessel.
[0006] This utility model provides a reaction vessel for safe chemical production, including a vessel body, an inner vessel liner inside the vessel body, a constant pressure tank between the inner vessel liner and the inner wall of the vessel body, an inner drain pipe fixedly connected to one side wall of the inner vessel liner, an outer drain pipe fixedly connected to the side wall of the vessel body away from the inner drain pipe and closer to the end, the outer drain pipe having an L-shaped structure, and a discharge pipe fixedly connected to the side wall of the vessel body away from the outer drain pipe and closer to the bottom edge, both the discharge pipe and the outer drain pipe communicating with the constant pressure tank.
[0007] Optionally, the inner drain pipe has a cylindrical structure, and the interior of the vessel is connected to the constant pressure tank through the inner drain pipe. The two opposite side walls of the inner drain pipe are rotatably connected with torsion springs, and a movable sealing plate is fixedly connected to one side of each torsion spring. Each movable sealing plate has a semi-conical structure.
[0008] Optionally, the top opening of the vertical section of the outflow pipe is rotatably connected to a sealing plate via a torsion spring, a support plate is fixedly connected to the side wall of the outflow pipe near the sealing plate, and an airbag is fixedly connected to the section of the outflow pipe near the sealing plate.
[0009] Optionally, a stop block is fixedly connected to the inner wall of the transverse section of the external drain pipe. The stop block has an annular structure. A blocking plate is provided inside the external drain pipe and on one side of the stop block. The blocking plate has a conical structure. A corresponding conical groove is provided on the side wall of the internal drain pipe opposite to the blocking plate.
[0010] Optionally, a fixing plate is fixedly connected to each of the two side walls inside the drain pipe that are opposite to one side of the blockage plate. The fixing plate has a semi-circular structure, and a spring is fixedly connected to the side wall of the fixing plate opposite to the blockage plate. One end of the spring is fixedly connected to the side wall of the blockage plate away from the stop block.
[0011] Optionally, a stirring rod is rotatably connected through the middle of the vessel body, one end of the stirring rod extends into the vessel liner, and a motor is detachably connected to the top of the stirring rod. A dispensing pipe is inserted through one side of the top of the vessel body, and one end of the dispensing pipe extends into the constant pressure tank.
[0012] Optionally, a discharge pipe is fixedly connected to the bottom side wall of the vessel, the discharge pipe is inserted into the bottom side wall of the vessel body, and a support column is fixedly connected to the bottom side wall of the constant pressure tank, with the top of the support column abutting against the bottom side wall of the vessel.
[0013] As can be seen from the above technical solution, the safe production reactor provided by this utility model has the following effect: when the pressure inside the reactor is too high, the gas pressure will enter the inner drain pipe and push open the two movable sealing plates. In this way, the gas pressure can enter the constant pressure tank through the unfolded movable sealing plates. Because the pressure inside the reactor is greater than the pressure inside the constant pressure tank at this time, the gas pressure in the constant pressure tank will not flow back into the reactor. As the gas pressure is discharged, the pressure inside the reactor gradually decreases, while the gas pressure in the constant pressure tank gradually increases, which will press the movable sealing plates back to close. At this point, the pressure inside the reactor and the constant pressure tank are constant, thus realizing the function of automatic pressure regulation inside the reactor and avoiding continuous pressure accumulation that could damage the reactor body.
[0014] When the pressure inside the constant pressure tank becomes too high, it will push open the blocking plate. This allows the pressure inside the constant pressure tank to flow out through the external drain pipe, thereby reducing the pressure inside the constant pressure tank. Reducing the pressure inside the constant pressure tank also reduces the pressure exerted on the movable blocking plate. As a result, when the pressure inside the vessel rises back to the previous level, the movable blocking plate will be pushed open to release the pressure, instead of requiring the pressure inside the vessel to reach an even higher level before pressure can be released due to the increased pressure inside the constant pressure tank, thus improving safety.

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.
[0022] like Figure 1-3 As shown, a reaction vessel for safe chemical production includes a vessel body 1, a vessel liner 2 inside the vessel body 1, a constant pressure tank 3 between the vessel liner 2 and the inner wall of the vessel body 1, an inner drain pipe 4 is fixedly connected to one side wall of the vessel liner 2, an outer drain pipe 5 is fixedly connected to the side wall of the vessel body 1 away from the inner drain pipe 4 and close to the end, the outer drain pipe 5 has an L-shaped structure, and a discharge pipe 7 is fixedly connected to the side wall of the vessel body 1 away from the outer drain pipe 5 and close to the bottom edge, both the discharge pipe 7 and the outer drain pipe 5 are connected to the constant pressure tank 3;
[0023] The inner pipe 4 is a cylindrical structure. The interior of the vessel liner 2 is connected to the constant pressure tank 3 through the inner pipe 4. The two opposite side walls of the inner pipe 4 are rotatably connected with torsion springs 13. Each torsion spring 13 is fixedly connected to one side with a movable sealing plate 12. Each movable sealing plate 12 is a semi-conical structure.
[0024] The top opening of the vertical section of the outflow pipe 5 is rotatably connected to a sealing plate 19 via a torsion spring 13. A support plate 20 is fixedly connected to the side wall of the outflow pipe 5 near the sealing plate 19. An airbag 18 is fixedly connected to the section of the outflow pipe 5 near the sealing plate 19. A stop block 14 is fixedly connected to the inner wall of the horizontal section of the outflow pipe 5. The stop block 14 has a ring structure. A blocking plate 15 is provided inside the outflow pipe 5 on one side of the stop block 14. The blocking plate 15 has a conical structure. A corresponding conical groove is opened on the side wall of the inner outflow pipe 4 opposite to the blocking plate 15. A fixing plate 16 is fixedly connected to both side walls of the outflow pipe 5 opposite to the blocking plate 15. The fixing plate 16 has a semi-circular structure. A spring 17 is fixedly connected to the side wall of the fixing plate 16 opposite to the blocking plate 15. One end of the spring 17 is fixedly connected to the side wall of the blocking plate 15 away from the stop block 14.
[0025] The technical effect of this solution is as follows: As the reaction proceeds, the pressure inside the vessel liner 2 continuously increases with the heat generated by the reaction. When the pressure exceeds the torque of the torsion spring 13, the movable sealing plate 12 connected to the torsion spring 13 will be pushed open by the air pressure. At this time, the air pressure inside the vessel liner 2 will also enter the constant pressure tank 3 through the inner drain pipe 4. This reduces the pressure inside the vessel liner 2, preventing damage to the vessel body 1 due to excessive pressure inside the vessel liner 2, and ensuring the safe and continuous operation of the vessel body 1. Because the space inside the constant pressure tank 3 is larger than that inside the vessel liner 2, the constant pressure tank 3 can bear a higher air pressure until the pressure inside the constant pressure tank 3 is constant with that inside the vessel liner 2. At this time, the movable sealing plate 12 will not be pushed open by the pressure inside the vessel liner 2 under the pressure of the constant pressure tank 3. The movable sealing plate 12 will only be opened if the pressure inside the vessel 2 is greater than that inside the constant pressure tank 3, but this would be dangerous. Therefore, an external drain pipe 5 is connected to the vessel body 1. When the pressure inside the constant pressure tank 3 is too high, it will open the sealing plate 15. In this way, the air pressure inside the constant pressure tank 3 will be discharged through the external drain pipe 5, thus reducing the pressure inside the constant pressure tank 3. This ensures that the pressure inside the vessel 2 does not need to rise to a higher level to open the movable sealing plate 12 and discharge, increasing the safety of operation. The airbag 18 can store the pressure of the discharge pipe 7, ensuring that the sealing plate 15 will not be opened unless the pressure inside the constant pressure tank 3 reaches a certain level. Furthermore, the constant pressure tank 3 can prevent damage to the vessel 2 from affecting the overall structure.
[0026] A stirring rod 10 is rotatably connected through the middle of the vessel body 1. One end of the stirring rod 10 extends into the vessel liner 2. A motor 11 is detachably connected to the top of the stirring rod 10. A delivery pipe 6 is inserted through one side of the top of the vessel body 1. One end of the delivery pipe 6 extends into the constant pressure tank 3. A discharge pipe 8 is fixedly connected to the bottom side wall of the vessel liner 2. The discharge pipe 8 is inserted through the bottom side wall of the vessel body 1. A support column 9 is fixedly connected to the bottom side wall of the constant pressure tank 3, and the top of the support column 9 rests against the bottom side wall of the vessel liner 2.
[0027] The technical effects of this solution are as follows: different media, such as coolant, can be injected into the constant pressure tank 3 through the injection pipe 6 as needed to cooperate with the reaction in the vessel liner 2 and ensure the smooth progress of the reaction. The media in the constant pressure tank 3 can be discharged through the discharge pipe 7. After different media are filled into the constant pressure tank 3, they will also apply pressure to the vessel liner 2 to ensure the stability of the vessel liner 2.
[0028] The device operates as follows: when the pressure inside the vessel 2 is too high, gas pressure enters the inner drain pipe 4 and pushes open the movable sealing plate 12. At this time, the pressure inside the vessel 2 will flow into the constant pressure tank 3 through the inner drain pipe 4, thereby reducing the pressure inside the vessel 2 and improving operational safety. Simultaneously, as the pressure inside the constant pressure tank 3 increases, to avoid affecting the normal pressure relief of the vessel 2, an outer drain pipe 5 is connected to the vessel body 1. When the pressure inside the constant pressure tank 3 is too high, it will push open the sealing plate 15, allowing the pressure inside the constant pressure tank 3 to be discharged through the outer drain pipe 5. This reduces the pressure inside the constant pressure tank 3, ensuring that the vessel 2 is within a safe pressure range for pressure relief, thus improving the overall operational safety of the vessel body 1. The required medium can be injected into the constant pressure tank 3 through the injection pipe 6, thereby cooperating with the reaction inside the vessel 2 to ensure that the materials inside the vessel 2 can react smoothly, thereby producing qualified products.
