Taking polystyrene production equipment as an example, this technology includes efficient reactor design and precise temperature and pressure control systems to ensure high efficiency in the polystyrene production process.

[0003] One of the processes in producing polystyrene involves mixing an initiator with polystyrene.

The initiator will flow into the interior of the metering tank. Since the rotating shaft is located slightly to the right of the center point of the metering tank, the metering tank will tilt after a certain amount of initiator is added, thus pouring the initiator into the metering container and then into the mixing tank for mixing reaction. When the metering tank is tilted, it will drive the rotating shaft, rotating rod one, and rotating rod two to rotate, thereby causing the sealing plate to block the opening at the top of the metering container, thus achieving the purpose of metered addition. In addition, after the lid is opened, different weights can be installed at the bottom of the metering tank to achieve different metering effects, improving flexibility. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a polystyrene production equipment with waste gas recovery function, including a mixing tank 1. The mixing tank 1 is used to mix polystyrene and an initiator to cause a reaction. A drive assembly for providing power is fixedly connected to the top of the mixing tank 1. The drive assembly includes a support block 2, one side of which is fixedly connected to the top of the mixing tank 1. A motor 3 is fixedly connected to the inner wall of the support block 2, providing stable support for the motor 3. A main shaft 4 is fixedly connected to the drive end of the motor 3. The outer side of the main shaft 4 is rotatably connected to the inner wall of the support block 2. After the motor 3 is started, it can drive the main shaft 4 to rotate. One end of the main shaft 4 is rotatably connected to the inner wall of the mixing tank 1. Multiple stirring plates 5 are fixedly connected to the outer side of the drive assembly. When the main shaft 4 rotates, it drives the multiple stirring plates 5 to rotate. At the same time, due to the special curved shape of the stirring plates 5, the waste gas after the initiator reacts with the polystyrene is guided upward.

[0034] The inner wall of the stirring plate 5 is fixedly connected to the outside of the main shaft 4. The top of the mixing tank 1 is detachably connected to the tank cover 6. The bottom of the tank cover 6 is fixedly connected to the rubber gasket 7. The outside of the rubber gasket 7 is slidably connected to the inner wall of the mixing tank 1. The rubber gasket 7 here is used to ensure a seal after the tank cover 6 is closed. The four corners of the side of the tank cover 6 near the rubber gasket 7 are fixedly connected to the insert post 8. The insert post 8 is engaged with the mixing tank 1. When the insert post 8 is engaged with the mixing tank 1, it can ensure that the tank cover 6 will not easily come off. The bottom of the mixing tank 1 is fixedly connected to the discharge pipe 9. The discharge pipe 9 here is used to discharge the polystyrene that has finished reacting.

[0035] Reference Figure 2 and Figure 4 A metering tank 10 is fixedly connected to the top of the mixing tank 1. The metering tank 10 is used to release the initiator in a metered manner. A lid 11 is detachably connected to the side of the metering tank 10 away from the mixing tank 1. The hole on the lid 11 is used to connect an external device containing the initiator. A rotating shaft 12 is rotatably connected to the inner wall of the metering tank 10. The rotating shaft 12 is installed at the center-right position of the metering tank 10. A metering container 13 is fixedly connected to the outside of the rotating shaft 12. After connecting the external device containing the initiator, the initiator can be output into the metering container 13. A counterweight is detachably connected to the bottom of the metering container 13. The operator can change the counterweight of different weights according to the required initiation dosage.

[0036] Rotating rod 14 is fixedly connected to both ends of the external shaft 12. Rotating rod 15 is rotatably connected to the other end of rotating rod 14. When the output initiator exceeds the balance ratio between the counterweight and the metering tank 13, it will tilt, thereby driving rotating rod 14 and rotating rod 15 to rotate. The other end of the two rotating rods 15 is rotatably connected to a sealing plate 16. One side of the sealing plate 16 is slidably connected to one side of the lid 11. When rotating rod 15 rotates, it can drive the sealing plate 16 to rotate, thereby blocking the hole on the lid 11 and preventing the initiator from continuing to be output. A threaded rod 17 is threadedly connected to the inner wall of the sealing plate 16. The outer side of the threaded rod 17 is slidably connected to the inner wall of the metering tank 10. When it is necessary to replace the counterweight according to the amount of initiator, the lid 11 can be opened first, then the threaded rod 17 can be unscrewed, and then the counterweight can be removed and replaced with a counterweight of the corresponding weight.

[0037] Reference Figure 2 and Figure 5A gas supply pipe 18 is fixedly connected to one side of the mixing tank 1. The exhaust gas guided to the top of the mixing tank 1 will be output from the gas supply pipe 18. The other end of the gas supply pipe 18 is fixedly connected to a filter box 19. The filter box 19 is used to filter the exhaust gas to make it suitable for emission. A box cover 20 is rotatably connected to one side of the filter box 19. Multiple filter plates 21 are detachably connected to the inner wall of the filter box 19. The multiple filter plates 21 are used to filter out impurities and harmful gases in the exhaust gas. Limiting strips 22 are fixedly connected to both sides of the filter plates 21. The outer side of the limiting strips 22 is slidably connected to the inner wall of the filter box 19. The limiting strips 22 here can ensure the stability of the filter plates 21. A pressure plate 23 is detachably connected to the side of the filter box 19 away from the filter plates 21. Multiple locking blocks 24 are fixedly connected to the side of the pressure plate 23 close to the filter box 19. The pressure plate 23 here is used to fix the box cover 20 to prevent gas leakage.

[0038] The outer side of the locking block 24 is slidably connected to the inner wall of the cover 20 and the outer side of the locking block 24 is slidably connected to the inner wall of the filter box 19. One side of the locking block 24 contacts one side of the limiting strip 22. The locking block 24 here can fill the gap between the top of the limiting strip 22 and the filter box 19, further improving the sealing effect. Both sides of the pressure plate 23 are fixedly connected with hook plates 25. The hook plates 25 here are used to ensure the locking of the filter box 19 and the pressure plate 23. At the same time, the hook plates 25 here are made of plastic and can be bent to a certain extent and then quickly reset. The side of the filter box 19 away from the mixing tank 1 is fixedly connected with the air outlet pipe 26. The gas that has been filtered to meet the safety standard will be output from the air outlet pipe 26 here, and then collected by the staff.

[0039] Working principle: First, polystyrene and initiator are mixed in mixing tank 1. Motor 3 drives main shaft 4 to rotate, and stirring plate 5 on main shaft 4 guides the exhaust gas upwards, reducing its accumulation in mixing tank 1. The exhaust gas guided to the top of mixing tank 1 is output to filter box 19 through gas delivery pipe 18. Multiple filter plates 21 here filter impurities and harmful gases from the exhaust gas. The filtered exhaust gas meets emission standards and is output through outlet pipe 26 for collection and treatment by staff. After a period of use, hook plate 25 can be pulled to temporarily bend it, disengaging it from filter box 19. Then, pressure plate 23 can be removed, and box cover 20 can be opened to remove the multiple filter plates 21 for cleaning.

[0040] In addition, the metering tank 10 at the top of the mixing tank 1 is used for metered release of the initiator. When the output of the initiator exceeds the balance between the counterweight and the metering tank 13, it will tip over, causing the rotating rods 14 and 15 to rotate. The sealing plate 16 will then rotate to block the hole on the tank cover 11, preventing further output of the initiator. When the counterweight needs to be replaced, the tank cover 11 can be opened, the threaded rod 17 can be unscrewed, the counterweight can be removed, and a counterweight of the corresponding weight can be replaced. Finally, the discharge pipe 9 at the bottom of the mixing tank 1 is used to discharge the polystyrene that has undergone reaction. Through the above steps, this equipment achieves effective recovery and treatment of waste gas during the polystyrene production process, while ensuring high efficiency and environmental protection in the production process.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
