[0003] China Patent Authorization Announcement No.: CN209222110U provides a rubber antioxidant DTPD reaction device, which heats the reaction solution in the reactor by circulating a heating medium in a heat preservation chamber. At the same time, since the heat preservation chamber covers the reactor, the reactor is insulated to prevent heat loss in the reactor and save energy. A stirring blade is arranged to stir the solution in the reactor to ensure uniform condensation reaction and improve product quality. A phase separator is arranged to collect and phase separate the solution after condensation of evaporated gas, which is beneficial to the collection of materials.

[0031] The feed assembly 2 includes a feed box 21, which is slidably connected to the fixed groove. A feed port is opened at the top of the feed box 21.

The fixed groove and the fixed plate 28 are used together to limit the moving trajectory of the feed box 21. A plurality of first springs 22 and a damper are fixedly connected between the fixed plate 28 and the reactor body 1. The damper is on the inner side of the first spring 22. When the staff adds the material for preparing the high-temperature resistant antioxidant into the feed box 21, the feed box 21 and the fixed plate 28 will move vertically downward, and the fixed plate 28 will compress the first spring 22.
[0032] See also Figure 4 The feed assembly 2 also includes a first sliding groove 25 , which is opened on the inner wall of the feed box 21 . The first sliding groove 25 is used to limit the moving trajectory of the baffle 27 .

[0038] Working principle: When the staff adds the material for preparing the high temperature resistant antioxidant into the feed box 21, the feed box 21 and the fixed plate 28 will move vertically downward, the fixed plate 28 will compress the first spring 22, and at the same time, the fixed block 23 will move relative to the inner wall of the second sliding groove 210. Because the fixed block 23 is fixedly connected to the baffle 27, the baffle 27 will move relative to the inner wall of the first sliding groove 25 and compress the second spring 26. The second discharge port 24 will be in an open state, and the material will be discharged through the second discharge port 24 and enter the interior of the reactor body 1 for reaction, and then the motor 3 will be started to control the stirring.
