[0002] 2,3,3',4'-Biphenyltetracarboxylic dianhydride is an important chemical raw material, mainly used in the synthesis of high-performance polyimide resins. In industrial production, this chemical substance is handled using specialized reaction vessels for the chemical synthesis process. Considering the cleanup of residues after the chemical reaction, the reaction vessel should be easy to clean and maintain. Conventional reaction vessels require operators to fully enter the inner wall of the vessel body for cleaning. Operators use handheld water guns to rinse the inner wall, followed by deep cleaning with brushes and other cleaning tools. This process necessitates disassembling the reaction vessel to facilitate access for cleaning. Since disassembly requires multiple operators, the process is time-consuming and labor-intensive. Therefore, a new 2,3,3',4'-biphenyltetracarboxylic dianhydride reaction vessel has been designed. Utility Model Content

[0026] It should be noted that when the operator cleans the inside of the reaction vessel body 1 after use, the operator can install the main scraper 4 and the auxiliary scraper 403 on the outer wall of the stirring blade 3. By adding the cleaning solution inside the reaction vessel body 1, the stirring blade 3 will drive the main scraper 4 and the auxiliary scraper 403 to rotate under the stirring of the stirring blade 3. The main scraper 4 and the auxiliary scraper 403 will clean the inside of the reaction vessel body 1. During the cleaning process, the main scraper 4 and the auxiliary scraper 403 will drive the main brush 501 and the auxiliary brush 502 to further clean the inside of the reaction vessel body 1.

[0027] Specifically, the sealing part 2 includes a sealing ring 201 and a sealing lug 202. The sealing lug 202 is arranged around the top edge of the reaction vessel body 1. The bottom end of the sealing ring 201 is hinged to the inner wall of the sealing lug 202. The top ends of the multiple sealing rings 201 are threadedly connected to multiple sealing bolts 203. The outer walls of the multiple sealing bolts 203 are threadedly connected to the top end of the vessel cover 102.

Then, when the motor 101 is started, the motor 101 will drive the stirring shaft 302 to rotate through the connecting rod 301.

[0031] Specifically, the end of the stirring blade 3 away from the stirring shaft 302 is provided with multiple connecting grooves 402. The inner walls of the multiple connecting grooves 402 are sleeved with the outer walls of multiple connecting pins 401. The connecting pins 401 are inserted and connected to the end away from the main scraper 4.

[0032] It should be noted that multiple connecting grooves 402 are provided on the outer wall of the stirring blade 3. When the operator installs the main scraper 4, the connecting pin 401 of the main scraper 4 is inserted through the inner wall of the connecting groove 402 to achieve quick installation between the main scraper 4 and the stirring blade 3.

[0033] Specifically, the end of the connecting pin 401 away from the main brush 501 is provided with multiple fixing bolts 5, and the outer wall of the multiple fixing bolts 5 is threadedly connected to the inner wall of the multiple auxiliary brushes 502.

[0034] It should be noted that the fixing bolt 5 and the connecting pin 401 are an integral part. When the operator puts the connecting pin 401 into the connecting groove 402, the fixing bolt 5 will be threaded through the inner wall of the connecting groove 402. The inner wall of the secondary scraper 403 will be connected to multiple connecting pins 401. Multiple secondary brushes 502 will then be installed by threading through the fixing bolt 5.

[0035] Specifically, a fixing plate 503 is provided at the end of the secondary brush 502 away from the main scraper 4, and the inner wall of the fixing plate 503 is threadedly connected to the outer wall of multiple fixing bolts 5.

Through the connection between the multiple fixing nuts and the fixing plate 503, the secondary brush 502 and the secondary scraper 403 are fixedly connected to the stirring blade 3.

[0037] Working principle of this utility model:

[0038] The specific operation is as follows: When cleaning the inside of the reaction vessel body 1, the operator can install the main scraper 4 on the outer wall of the stirring blade 3 using the connecting pin 401. The connecting pin 401 needs to be inserted and connected to multiple connecting grooves 402 on the outer wall of the stirring blade 3. Then, the operator needs to insert the outer wall of the auxiliary scraper 403 through one end of the connecting pin 401 to install the auxiliary scraper 403 on one side of the stirring blade 3. Next, the operator inserts the internal thread of the auxiliary brush 502 through the outer wall of the fixing bolt 5. Finally, the fixing plate 503 is threaded to one end of the fixing bolt 5. The auxiliary scraper 403 and the auxiliary brush 502 are fixed to the stirring blade 3 under the threaded connection of the fixing plate 503. The operator can flip the sealing ring 201 to the top of the tank cover 102 using the sealing lug 202, and manually thread the sealing bolt 203 perpendicular to the top of the tank cover 102. The tank cover 102 is secured by multiple sealing bolts. The threaded connection of 203 secures the device to the top of the reaction vessel body 1. The operator can start the motor 101, and the output of the motor 101 will drive the stirring shaft 302 to rotate through the connecting rod 301.
