Specific implementation method:
[0011] Reference Figure 1 Figure 2 Figure 3 Figure 4 The raw material proportioning device for the production of imidazolidine is characterized in that it comprises a reaction tank body 1 and a feed through hole 2 arranged above the side surface of the reaction tank body 1, a sealing device 3 is movably inserted at the center of the inner end of the feed through hole 2, a feed pipe 4 is connected to the edges around the outer surface of the feed through hole 2, a protective outer cover 5 is inserted at the center of the outer surface of the feed pipe 4, a collection device 6 is inserted at the center of the outer surface of the protective outer cover 5, and a sealing upper cover 7 is inserted at the center of the outer surface of the collection device 6 The sealing device 3 includes a chuck 3-1, a spring 3-2, a plug 3-3 and a turntable 3-4. The outer surface of the chuck 3-1 is connected to a spring 3-2 at the upper edge and the left and right edges. The outer surface of the chuck 3-1 is connected to a plug 3-3 at the center of the outer surface. The turntable 3-4 is inserted at the center of the outer surface of the plug 3-3. The turntable 3-4 and the plug 3-3 are connected to each other by a bearing. The plug 3-3 is inserted in the feed through hole 2. The protective cover 5 includes a plug 5-1, a right The right cavity 5-2, the left cavity 5-3 and the leakage hole 5-4 are provided at the center of the right edge of the plug column 5-1, and the left cavity 5-3 is provided at the center of the left side of the plug column 5-1. The interior of the left cavity 5-3 is connected with the interior of the right cavity 5-2. A leakage hole 5-4 is provided below the inner side surface of the left cavity 5-3. The inner diameter of the left cavity 5-3 is larger than the inner diameter of the right cavity 5-2. The left end of the plug column 5-1 is inserted into the feed pipe 4. The left surface of the plug column 5-1 is connected to the rotating The right surface of the disk 3-4 is in contact, and the material collecting device 6 includes a material pipe 6-1, a material hole 6-2, a slider 6-3 and an external thread 6-4. The material hole 6-2 is provided at the lower left side of the side surface of the material pipe 6-1, and the slider 6-3 is symmetrically connected to the upper and lower left edge of the side surface of the material pipe 6-1.

[0012] When in use, the staff first loads an appropriate amount of auxiliary raw materials into the material tube 6-1 on the collecting device 6, and then the staff tightens the sealing cover 7 on the material tube 6-1, and then the staff inserts the plug 5-1 on the protective outer cover 5 into the feed pipe 4 and rotates the plug 5-1. Since there is a threaded connection between the plug 5-1 and the feed pipe 4, the plug 5-1 is tightened into the feed pipe 4, and then the plug 5-1 contacts the turntable 3-4 on the sealing device 3 and drives the turntable 3-4 to rotate in the plug 3-3. At the same time, the plug 5-1 pushes the plug 3-3 out of the feed through hole 2, so that the leakage hole 5-4 is completely inserted into the reaction tank body 1.
