Description

Technical Field

[0001] The utility model relates to the technical field of glyphosate processing, in particular to a reaction kettle for glyphosate processing. Background Art

[0002] Glyphosate (PMIDA) is the main raw material for the production of highly efficient, low-toxic and broad-spectrum post-emergence herbicides, and is also an important intermediate in the fields of pesticides, pharmaceuticals, rubber, electroplating and dyes. In the production process of glyphosate, iminodiacetonitrile and inorganic acid need to be added into the reaction kettle for mixed acidolysis. Then, water and iminodiacetic acid recycling liquid are added, and alkalization is carried out with 25-28% concentrated ammonia water by mass fraction, and the pH is adjusted to 1-3; after cooling, filtering and crystallization, iminodiacetic acid is obtained. During this process, a reaction kettle is required for stirring.

[0003] In the prior art, generally as Figure 5 shown, various materials are directly poured into the interior of the reaction kettle 42 through the feed pipe 41, and then the tail gas generated during the reaction process is discharged through the tail gas pipe 43, and then stirring is carried out. However, the above technical means have certain defects. For example, if these mixed materials directly enter the interior of the reaction kettle 42 through the feed pipe 41, some non-liquid materials (such as iminodiacetonitrile) will fall into the same position and cannot be evenly sprinkled in the liquid materials, resulting in a reduction in the reaction efficiency. Content of the Utility Model

A first toothed ring is fixedly connected to the outer surface of the connecting pipe. The top side inside the kettle body is rotatably connected with a gear meshed with the first toothed ring. The top of the kettle body is fixedly installed with a first motor, and the output end of the first motor is fixedly connected with the gear through a coupling.
