[0002] In the production process of 4,4'-diaminodiphenyl ether, it is necessary to stir the production raw materials of 4,4'-diaminodiphenyl ether to help the production of 4,4'-diaminodiphenyl ether better Combined with the catalyst, the production efficiency of 4,4'-diaminodiphenyl ether is improved. Although the existing stirring device for the production of 4,4'-diaminodiphenyl ether can be used for the production of diaminodiphenyl ether Stirring, but in the production process, the raw materials for the production of 4,4'-diaminodiphenyl ether are often mixed with a small amount of impurities, and the stirring device for the production of 4,4'-diaminodiphenyl ether is difficult to produce Impurities in the raw materials are effectively filtered, resulting in a reduction in the quality of 4,4'-diaminodiphenyl ether, which has brought great distress to users, thus designing a 4,4'-diaminodiphenyl ether Double stirred reactor for ether production

A double-stirred reactor for the production of 4,4'-diaminodiphenyl ether. The invention belongs to the technical field of chemical production equipment. The top of the lifting device is fixedly connected by the cover body, and the upper and lower ends of the second gear are respectively provided with annular grooves, and a movable block is arranged in the annular groove, and the movable block is fixedly connected with one end of the vertical rod of the L-shaped connecting rod. The gear can be meshed with the second gear, and the bottom side of the reactor body is fixedly connected with a discharge pipe with a valve. Through the present invention, raw materials can be stirred with multiple parts, and there are fewer power devices, and after the stirring is completed, more careful filtration can be carried out from bottom to top, and the stirring of raw materials and the up and down movement of the net bag can be achieved through forward and reverse rotation. The work of the motor can be driven, saving energy consumption.
