The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a technical solution: a low-temperature reaction vessel, including a reaction vessel 1, a hoop 13, and a scraper 9. The reaction vessel 1 is provided with a reaction vessel cover 2; the hoop 13 is provided with a mounting block 14, and the mounting block 14 is provided with a nut 15 and a bolt 16. Both the reaction vessel 1 and the reaction vessel cover 2 are provided with annular rings 12, and there are two sets of annular rings 12. The nuts 15 and bolts 16 are used to limit the two sets of annular rings 12; the scraper 9 is located inside the reaction vessel 1.
[0022] Furthermore, a feed pipe 10 is fixedly installed at the bottom of the reactor 1. A hole is opened at the bottom of the reactor 1, located directly above the feed pipe 10, and a shut-off valve is installed on the feed pipe 10. A sealing groove is opened at the top of the reactor 1. A sealing ring 11 is fixedly installed at the bottom of the reactor cover 2, and the sealing ring 11 on the reactor cover 2 is located within the sealing groove on the reactor 1. A reducer 3 is fixedly installed at the top of the reactor cover 2. A drive motor 4 is installed on the reducer 3. A rotating rod 6 is installed at the output end of the reducer 3. The shaft of the drive motor 4 is fixedly connected to the input end of the reducer 3. A stirring rod 7 is fixedly installed on the outer wall of the rotating rod 6. A support rod 8 is fixedly installed at one end of the stirring rod 7, and a scraper 9 is fixedly installed at one end of the support rod 8. One side of the scraper 9 contacts the inner wall of the reactor 1 but is not fixed. There are two sets of hoop rings 13. Both the outer wall of the reactor 1 and the outer wall of the reactor cover 2 are fixedly equipped with annular rings 12. An installation groove is opened inside the hoop rings 13. The two sets of annular rings 12 are located in the mounting grooves on the hoop rings 13. The outer walls of the two sets of hoop rings 13 are fixedly mounted with mounting blocks 14. There are two sets of mounting blocks 14. The mounting blocks 14 have connecting holes inside. One end of the bolt 16 passes through the connecting holes on the two sets of mounting blocks 14 and extends to one side of one set of mounting blocks 14, and a nut 15 is threaded on it. The top of the reactor cover 2 is fixedly mounted with a feed hopper 5. One end of the feed hopper 5 extends into the interior of the reactor cover 2. This arrangement can connect the two sets of hoop rings 13. When the two sets of hoop rings 13 are connected, the reactor 1 and the reactor cover 2 can be connected through the annular rings 12.

Furthermore, the scraper 9 can scrape off the material adhering to the inner wall of the reactor 1, avoiding the situation where the material adheres to the reactor 1 and is difficult to discharge.
[0023] Working principle: During use, various pharmaceutical materials are added into the reactor 1 through the feed hopper 5. Then, the drive motor 4 is started. The drive motor 4 drives the rotating rod 6 to rotate through the reducer 3. The rotation of the rotating rod 6 drives the stirring rod 7 to rotate. The rotation of the stirring rod 7 stirs the materials inside the reactor 1. After the raw materials have reacted, they are discharged through the discharge pipe 10. During the discharge, the scraper 9 rotates to scrape off the materials adhering to the inside of the reactor 1. When it is necessary to disassemble the reactor 1 and the reactor cover 2, rotate the bolt 16 to separate the nut 15 from the bolt 16, and then disassemble the two sets of hoops 13. Then the reactor 1 and the reactor cover 2 can be separated.
