Abstract
Description
Technical Field
[0001] This utility model relates to the field of petroleum resin technology, and in particular to a petroleum resin degassing reactor. Background Technology
[0002] During the production of petroleum resins, volatile substances, low molecular weight polymers, and gases such as oxygen are inevitably introduced due to polymerization reactions and other processes. The presence of these gases can adversely affect the quality of petroleum resins, such as causing the resin to darken in color, produce odors, and reduce thermal stability. Therefore, degassing treatment is necessary to remove these gases and improve the quality of petroleum resins.
[0003] Existing petroleum resin degassing reactors heat the petroleum resin to a certain temperature, causing the volatile components in the resin to vaporize. Then, a motor is started, which drives the stirring blades to rotate vertically, stirring the resin in the reactor. This ensures that the resin is heated evenly within the reactor, avoiding localized overheating that could lead to resin degradation, thereby achieving degassing.
[0004] However, the rotation of vertical stirring blades easily creates a fixed flow field, resulting in a large difference in resin mixing effect between the edge and center areas of the reactor. This leads to uneven heating and makes it difficult to effectively break down the viscous layer formed on the resin surface. Consequently, some volatile components are trapped inside the resin and cannot escape in time, prolonging the degassing time. This not only increases production energy consumption and reduces production efficiency, but may also affect the final quality of petroleum resin due to incomplete degassing. Utility Model Content
[0005] The existing petroleum resin degassing reactor has a significant difference in resin mixing effect between the edge area and the center area, resulting in uneven heating and difficulty in effectively breaking down the viscous layer formed on the resin surface. This causes some volatile components to be trapped inside the resin and unable to be discharged in time.

[0007] Preferably, the connecting rod has a groove, and the rotating rod is rotatably connected to the inner side of the connecting rod through the groove.
[0008] Preferably, multiple sets of stirring blades are provided, and the multiple sets of stirring blades are arranged in a linear array on the outside of the rotating rod.

[0012] As a preferred material, the sealing ring is made of fluororubber, which has excellent high temperature resistance and chemical corrosion resistance.
[0013] The beneficial effects of this invention are as follows: Compared with traditional petroleum resin degassing reactors, the mixing effect of resin in the edge area and the center area of the reactor is significantly different, resulting in uneven heating and difficulty in effectively breaking down the viscous layer formed on the resin surface. This leads to some volatile components being trapped inside the resin and unable to be discharged in time. This device starts a vacuum pump, which extracts all the gas inside the reactor body through a connecting pipe, creating a vacuum inside the reactor body. The drive motor is then started, which drives the connecting rod to rotate. The connecting rod drives the rotating rod to move, which in turn drives the gear along the gear ring. This causes the gear to rotate, which in turn drives the rotating rod to rotate inside the connecting rod. The rotating rod then drives the stirring blade to rotate, resulting in planetary rotation, which uniformly stirs the resin and makes the heating more uniform. When the petroleum resin is heated to a certain temperature, the volatile components in the resin are vaporized. In a vacuum environment, the partial pressure of the volatile components is reduced, promoting their release from the resin. Through vacuum and stirring, the volatile components are rapidly and thoroughly removed. Attached Figure Description

The inner side of the rotating rod 806 is used to limit the movement of the rotating rod 806. Multiple sets of stirring blades 808 are arranged in a linear array on the outer side of the rotating rod 806. The multiple sets of stirring blades 808 make the resin mixing more uniform. Petroleum resin is added to the reactor body 1. The heating device 5 is started by the control device 4 to heat the resin inside the reactor body 1. The vacuum pump 801 is started. The vacuum pump 801 extracts all the gas in the reactor body 1 through the connecting pipe 802, so that the inside of the reactor body 1 is in a vacuum state. The drive motor 803 is started. The drive motor 803 drives the connecting rod 805 to rotate. The connecting rod 805 drives the rotating rod 806 to move, and the rotating rod 806 drives the gear 807 to move along the gear ring 804, causing the gear 807 to rotate.

[0022] Please see Figure 5In this embodiment, the fixing assembly includes a sealing ring 901. The sealing ring 901 is fixedly connected to the upper end of the reactor body 1.

[0023] During operation, petroleum resin is added to the reactor body 1. The heating device 5 is activated via the control device 4 to heat the resin inside the reactor body 1. The vacuum pump 801 is activated, extracting all gas from the reactor body 1 through the connecting pipe 802, creating a vacuum inside the reactor body 1. The drive motor 803 is activated, rotating the connecting rod 805. The connecting rod 805 moves the rotating rod 806, which in turn moves the gear 807 along the gear ring 804, causing the gear 807 to rotate. The gear 807 then rotates the rotating rod 806 inside the connecting rod 805, which in turn rotates the stirring blade 808, resulting in planetary rotation that evenly stirs the resin and ensures more uniform heating. When the petroleum resin reaches a certain temperature, the volatile components in the resin vaporize. Under vacuum conditions, the partial pressure of these volatile components is reduced, promoting... The resin is extracted from the resin. Through vacuum and stirring, the volatile components are quickly and thoroughly removed. After degassing, the electric valve 7 is activated, and the resin is discharged from the discharge pipe 6. By rotating the fixed plate 906, the fixed plate 906 drives the threaded rod 905 to rotate inside the rotating block 904, thereby causing the fixed plate 906 to disengage from the groove on the first fixed block 902, releasing the limiting fixation of the first fixed block 902. Then, the rotating block 904 is rotated to move the fixed plate 906 away from the top of the first fixed block 902. Then, the cover plate 3 is pulled to open it. When fixing the cover plate 3, the fixed plate 906 is rotated to the top of the first fixed block 902 by rotating the rotating block 904. Then, the fixed plate 906 is rotated, and the fixed plate 906 drives the threaded rod 905 to rotate. The threaded rod 905 drives the fixed plate 906 to move, so that the fixed plate 906 engages with the groove on the first fixed block 902, thereby fixing the cover plate 3.
[0024] Through the above steps, petroleum resin is added to the reactor body 1. The heating device 5 is activated by the control device 4 to heat the resin inside the reactor body 1. The vacuum pump 801 is activated, and the vacuum pump 801 extracts all the gas inside the reactor body 1 through the connecting pipe 802, making the inside of the reactor body 1 a vacuum state. The drive motor 803 is activated, and the drive motor 803 drives the connecting rod 805 to rotate. The connecting rod 805 drives the rotating rod 806 to move, and the rotating rod 806 drives the gear 807 to move along the gear ring 804. The gear 807 rotates, which in turn drives the rotating rod 806 to rotate inside the connecting rod 805. The rotating rod 806 then drives the stirring blade 808 to rotate, thus performing planetary rotation to uniformly stir the resin and make the heating more uniform. When the petroleum resin is heated to a certain temperature, the volatile components in the resin are vaporized. Under vacuum conditions, the partial pressure of the volatile components is reduced, promoting their removal from the resin. Through vacuum and stirring, the volatile components are quickly and thoroughly removed. After degassing is completed, the electric valve 7 is activated, and the resin is discharged from the discharge pipe 6.
