It is a reaction vessel that can withstand certain pressure and temperature and has good sealing performance, used to promote and complete chemical reactions under specific conditions.

[0003] When existing isobutylene sulfide reactors need maintenance, the toxicity and flammability of isobutylene inside the reactor can easily cause injury and poisoning to workers if the internal cleaning of the reactor is not thorough during maintenance. Moreover, the high oxygen content inside the reactor during maintenance can easily lead to combustion or explosion accidents. Utility Model Content

[0004] In view of the problems existing in the above-mentioned sulfurized isobutylene reactor, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a safe maintenance type of sulfurized isobutylene reactor, which solves the problems of incomplete cleaning of the reactor interior during maintenance, which can easily cause injury and poisoning to workers, and the problem that excessive oxygen content inside the reactor during maintenance can easily lead to combustion or explosion accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A maintenance-safe sulfurized isobutylene reactor includes a mounting frame, a reactor body is fixedly connected inside the mounting frame, a reactor lid is snapped onto the top of the reactor body, a storage chamber is fixedly connected to the top of the reactor lid, a pump is fixedly connected to the surface of the reactor lid, the output end of the pump is fixedly sleeved with the side wall of the storage chamber, an annular hollow plate is fixedly connected to the bottom of the reactor lid, and multiple connecting pipes are fixedly sleeved on one end of the annular hollow plate. One end of each connecting pipe is fixedly sleeved with the inner wall of the storage chamber. Multiple nozzles are fixedly sleeved on the other side wall of the empty plate. A drive mechanism is provided inside the vessel body. Multiple cleaning plates are connected to the vessel body through the drive mechanism. A replacement tube is fixedly sleeved on one side wall of the vessel body. A first solenoid valve is fixedly sleeved on the wall of the replacement tube. A gas monitoring device is fixedly sleeved inside the vessel lid. A safety valve is fixedly sleeved inside the vessel lid. A treatment tube is fixedly sleeved on the bottom of the vessel body. A treatment chamber is fixedly connected to the surface of the mounting frame. One end of the treatment tube is fixedly sleeved on the side wall of the treatment chamber. A second solenoid valve is fixedly sleeved on the rod wall of the treatment tube.

[0007] Preferably, the driving mechanism includes a motor, a driving rod, and a stirring paddle. The side wall of the motor is fixedly connected to the bottom wall of the vessel. One end of the driving rod is fixedly connected to the output end of the motor. The other end of the driving rod is fixedly connected to one end of the side wall of the stirring paddle.

[0011] Preferably, the surface of the vessel lid is symmetrically fixedly connected with two lifting rings.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. In this utility model, during maintenance, an ethanol solution inside the storage chamber is driven by a pump to enter the interior of the annular hollow plate through each connecting pipe. The solution is then sprayed onto the inner wall of the vessel through each nozzle. A drive mechanism then drives a cleaning plate to scrape away the sulfurized isobutylene adhering to the inner wall of the vessel, causing the ethanol solution to dissolve the sulfurized isobutylene and reduce its concentration. Furthermore, the vessel is easy to clean after being sprayed with the ethanol solution, avoiding residue when the cleaning plate scrapes the inner wall of the vessel and improving the cleaning effect.

[0014] 2. In this utility model, after the internal cleaning of the vessel is completed, a gas monitoring device is used to monitor the oxygen content inside the vessel. Inert nitrogen gas is slowly introduced into the vessel through a displacement pipe. When the oxygen content inside the vessel decreases to a suitable concentration, the gas inside the vessel is slowly released through a safety valve to reduce the oxygen content inside the vessel. Since isobutylene sulfide itself is flammable, this design avoids ignition sources such as static electricity and sparks generated during testing that could cause combustion or even explosion inside the vessel, thus protecting the safety of the personnel.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a maintenance-safe sulfurized isobutylene reactor.

[0024] This utility model provides, for example Figure 1-4The diagram shows a maintenance-safe type isobutylene sulfide reactor, comprising a mounting frame 1, a reactor body 2 fixedly connected inside the mounting frame 1, a reactor cover 3 snapped onto the top of the reactor body 2, a storage chamber 4 fixedly connected to the top of the reactor cover 3, a pump 5 fixedly connected to the surface of the reactor cover 3, the output end of the pump 5 fixedly sleeved with the side wall of the storage chamber, an annular hollow plate 6 fixedly connected to the bottom of the reactor cover 3, multiple connecting pipes 7 fixedly sleeved on one side wall of the annular hollow plate 6, one end of each connecting pipe 7 fixedly sleeved with the inner wall of the storage chamber 4, and multiple nozzles 8 fixedly sleeved on the other side wall of the annular hollow plate 6. A drive mechanism is installed inside the reactor body 2. 2. Multiple cleaning plates 9 are connected via a drive mechanism. A replacement pipe 10 is fixedly sleeved on one side wall of the vessel body 2. A first solenoid valve 11 is fixedly sleeved on the wall of the replacement pipe 10. A gas monitoring device 12 is fixedly sleeved inside the vessel cover 3. A safety valve 13 is fixedly sleeved inside the vessel cover 3. A processing pipe 14 is fixedly sleeved at the bottom of the vessel body 2. A processing chamber 15 is fixedly connected to the surface of the mounting frame 1. One end of the processing pipe 14 is fixedly sleeved on the side wall of the processing chamber 15. A second solenoid valve 16 is fixedly sleeved on the rod wall of the processing pipe 14. A feed pipe 23 is fixedly sleeved on one side wall of the vessel body 2. A discharge pipe 24 is fixedly connected to the other side wall of the vessel body 2.

[0025] During maintenance, the pump 5 drives the ethanol solution inside the storage chamber 4 to enter the interior of the annular hollow plate 6 through each connecting pipe 7. The solution is then sprayed onto the inner wall of the vessel body 2 through each nozzle 8. The drive mechanism then drives the cleaning plate 9 to scrape away the sulfurized isobutylene adhering to the inner wall of the vessel body 2, causing the ethanol solution to dissolve the sulfurized isobutylene and reduce its concentration. The vessel body 2 is easy to clean after being sprayed with the ethanol solution, avoiding residue when the cleaning plate 9 scrapes the inner wall of the vessel body 2 and improving the cleaning effect. Finally, the second solenoid valve 16 is opened to allow the cleaned solution to enter the interior of the treatment chamber 15 through the treatment pipe 14 for further treatment, thus emptying the interior of the vessel body 2 for easy maintenance.

[0026] After the internal cleaning of the vessel body 2 is completed, the oxygen content inside the vessel body 2 is monitored using a gas monitoring device 12. Inert nitrogen gas is slowly introduced into the vessel body 2 through the displacement pipe 10. When the oxygen content inside the vessel body 2 decreases to a suitable concentration, the gas inside the vessel body 2 is slowly released through the safety valve 13 to reduce the oxygen content inside the vessel body 2. Since isobutylene sulfide itself is flammable, this prevents ignition sources such as static electricity and sparks generated during the test from causing combustion or even explosion inside the vessel body 2, thus protecting the safety of the staff.

[0027] To better reduce the concentration of isobutylene sulfide, such as Figure 1As shown, the driving mechanism includes a motor 17, a drive rod 18, and a stirring paddle 19. The side wall of the motor 17 is fixedly connected to the bottom wall of the vessel body 2. One end of the drive rod 18 is fixedly connected to the output end of the motor 17. The other end of the drive rod 18 is fixedly connected to one end of the side wall of the stirring paddle 19. The rod wall of the drive rod 18 is fixedly connected to one end of the side wall of each cleaning plate 9.

[0028] The motor 17 drives the stirring paddle 19 to rotate inside the vessel 2 via the drive rod 18. The drive rod 18 also drives each cleaning plate 9 to scrape the inner wall of the vessel 2. When cleaning the inside of the vessel 2, the stirring paddle 19 stirs the sulfurized isobutylene and ethanol solution, which accelerates the reaction rate and reaction quality, and better reduces the concentration of sulfurized isobutylene.

[0029] To ensure more stable operation of the cleaning board 9, such as Figure 1-4 As shown, a support rod 20 is fixedly connected to the other side wall of each cleaning plate 9, and a rotating sleeve 21 is fixedly connected to the rod wall of each support rod 20. A rotating column 22 is fixedly connected to the bottom of the lid 3, and one side wall of the rotating column 22 is rotatedly connected to the inside of the rotating sleeve 21.

[0030] By using a rotating sleeve 21, which is connected to the corresponding cleaning plate 9 via each support rod 20, each cleaning plate 9 is limited to rotate inside the rotating sleeve 21 by one end of the rotating column 22 during operation. This makes the cleaning plate 9 work more stably and avoids deformation of the cleaning plate 9, which could lead to a large amount of residue during the cleaning process.

[0031] For ease of maintenance, such as Figure 1-4 As shown, two lifting rings 25 are symmetrically fixedly connected to the surface of the lid 3.

[0032] By using two lifting rings 25, the lid 3 can be separated from the body 2 during maintenance, making maintenance easier.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
