[0002] A polymerization kettle is a container for polymerization reactions, and a polymerization kettle is required for the production of polyacrylamide. The design and operating conditions of the polymerization kettle will be adjusted according to the specific requirements of the polymerization reaction. Generally speaking, the polymerization kettle needs to have good heat transfer and stirring properties to ensure that the reaction materials can be evenly mixed and maintain a suitable temperature. In addition, the polymerization kettle also needs to be able to withstand a certain pressure and temperature, and have good sealing properties to prevent the leakage of reactants and the entry of external impurities. The polymerization kettle can be used for a variety of polymerization reactions, such as free radical polymerization, ionic polymerization, polycondensation, etc., and is widely used in the production of plastics, rubber, fiber, coatings, adhesives and other industries. Different polymerization reactions and product requirements may require polymerization kettles of different types and specifications to meet process requirements and production needs.

[0003] According to the publicly disclosed publication number: CN219701919U, in the above application, the feeding is carried out at one time through the sealed door. Since the polymerization kettle body is a closed space, the staff cannot observe the polymerization of the raw materials inside it. If too much raw materials are added at one time, it is uncertain whether the raw materials can be directly mixed evenly. Moreover, all the raw materials are fed through the sealed door, which is not convenient for feeding each raw material separately for proportioning and mixing, and may also cause other raw materials to be contaminated when the raw materials are added.

[0024] The bottom surface of the control box 21 is fixedly connected to the top surface of the kettle body 1, the top surface of the control box 21 is fixedly connected to the chassis 22, the inner wall of the chassis 22 is fixedly connected to the motor 23, the surface of the control box 21 passes through and is rotatably connected to a rotating shaft 24, the top surface of the rotating shaft 24 is fixedly connected to the output shaft of the motor 23, the rotating shaft 24 also passes through the kettle body 1 and is rotatably connected, the rotating shaft 24 passes through and is fixedly connected to a stirring blade 25 and a heating rod 26, the connecting plate 27 is fixedly connected to the inner wall of the control box 21, the top surface of the connecting plate 27 is fixedly connected to a feeding pipe 28, the bottom surface of the connecting plate 27 is fixedly connected to a connecting pipe 29, and the bottom surface of the connecting pipe 29 passes through the kettle body 1 and is fixedly connected. The rotating shaft 24 is located at one end of the control box 21 and penetrates and is fixedly connected with a rotating ring 210. The surface of the rotating ring 210 is fixedly connected with a lever 211. When the motor 23 is started, the output shaft of the motor 23 will drive the rotating shaft 24 to rotate together, and the rotating shaft 24 will drive the lever 211 to rotate through the fixed rotating ring 210. The inner wall of the connecting plate 27 is rotatably connected with a rotating disk 212, and the side of the rotating disk 212 is fixedly connected with a linkage rod 213. The continuous rotation of the rotating disk 212 will force the abutment groove 219 to abut against the lower slide bar 220, thereby forcing the sealing block 221 to rotate to a certain extent with the upper slide bar 222 as the axis and the upper slide bar 222 being located in the slide groove 223 at the same time, so that the circumferentially arranged sealing block 221 is unfolded, so that the raw materials enter the kettle body 1 through the connecting plate 27 and the connecting pipe 29. The connecting plate 27 is provided with an arc groove 214 on one side close to the lever 211, and the linkage rod 213 penetrates the arc groove 214 and is slidably connected. The surface of the linkage rod 213 is fixedly connected with a round block 215 and a linkage block 216, and the inner wall of the control box 21 is fixedly connected with an arc rod 217, which penetrates the linkage block 216 and is slidably connected. The top surface of the rotating disk 212 is provided with a resistance groove 219, and the inner wall of the connecting disk 27 is provided with a slide groove 223. The lower slide rod 220 drives the sealing block 221 to slide, and the sealing block 221 drives the upper slide rod 222 to slide along the slide groove 223, but the slide groove 223 is short. After the upper slide rod 222 slides a certain distance, it will resist the tail end of the slide groove 223. At this time, the rotating disk 212 continues to rotate, which forces the resistance groove 219 to resist the lower slide rod 220.

After the lever 211 rotates a certain distance, it will interfere with the round block 215, thereby forcing the round block 215 to drive the linkage rod 213 to rotate the turntable 212. When the turntable 212 rotates, it will drive the interference groove 219 on the surface to rotate together, and the interference groove 219 will drive the lower slide rod 220 slidably connected inside it to slide together, so that the lower slide rod 220 drives the sealing block 221 to slide, and the upper slide rod 222 passes through the slide groove 223.An arc spring 218 is fixedly connected to the surface of the linkage block 216. When the linkage rod 213 is moved, the linkage block 216 will be driven to rotate with the center line of the turntable 212 as the axis, so that the linkage block 216 slides along the trajectory of the arc rod 217 and compresses the arc spring 218. The end of the arc spring 218 away from the linkage block 216 is fixedly connected to the inner wall of the control box 21. After the rotating ring 210 rotates a certain distance and the distance of the lever 211 is not enough to move the round block 215, the compressed arc spring 218 will drive the linkage block 216 and reset the linkage rod 213 at the same time.

[0025] Based on the above embodiment, when the polyacrylamide is mixed and produced, the valve 6 on the surface of the discharge pipe 5 is first closed, and the sealing block 221 is in a closed state in the initial state. Then, the raw materials for producing polyacrylamide, such as acrylamide monomer, initiator, chain transfer agent and deionized water, are prepared, and then the motor 23 is started to pour the acrylamide monomer and deionized water into the symmetrical feed pipe 28 respectively. The closed sealing block 221 will block the raw materials from passing through the feed pipe 28 and the connecting plate 27. When the motor 23 is started, the output shaft of the motor 23 will drive the rotating shaft 24 to rotate together, and the rotating shaft 24 will drive the lever 2 through the fixedly connected rotating ring 210. 11 is rotated, and after the lever 211 rotates a certain distance, it will contact the round block 215, thereby forcing the round block 215 to drive the linkage rod 213 to rotate the turntable 212. When the turntable 212 rotates, it will drive the contact groove 219 provided on the surface to rotate together, and the contact groove 219 will drive the lower sliding rod 220 connected thereto to slide together, so that the lower sliding rod 220 drives the sealing block 221 to slide, and the sealing block 221 drives the upper sliding rod 222 to slide along the sliding groove 223, but the distance of the sliding groove 223 is short, and after the upper sliding rod 222 slides a certain distance, it will contact the tail end of the sliding groove 223, and at this time, the continuous rotation of the turntable 212 will force the contact groove 219 to contact the upper sliding rod 222. The lower slide bar 220 moves downward, thereby forcing the sealing block 221 to rotate to a certain extent with the upper slide bar 222 as the axis and the upper slide bar 222 being located in the slide groove 223 at the same time, so that the circumferentially arranged sealing block 221 is expanded, and the raw material enters the kettle body 1 through the connecting plate 27 and the connecting pipe 29. When the linkage rod 213 is moved, the linkage block 216 is driven to rotate with the center line of the rotating disk 212 as the axis, so that the linkage block 216 slides along the track of the arc rod 217 and compresses the arc spring 218. When the lever 211 is not far enough to move the round block 215 after the rotating ring 210 rotates a certain distance, the compressed arc spring 218 drives the linkage block 2 16 and at the same time, the linkage rod 213 is reset together, so that the turntable 212 rotates in the opposite direction and drives the sealing block 221 to reset, so that the raw materials in the feed pipe 28 cannot pass through the connecting plate 27 again, and the lever 211 is repeatedly moved, so that only a certain amount of raw materials can pass through the connecting pipe 29 each time to achieve the effect of quantitative feeding, so that the raw materials entering the kettle body 1 each time can be stirred and heated to a certain degree by the stirring blades 25 and the heating rods 26 before adding, so that the raw materials inside the kettle body 1 can have a certain degree of mixing time when mixing, so that the raw materials can be mixed and heated more fully, and there is no need for manual quantitative feeding, making the feeding more convenient.

[0026] Through the quantitative feeding of the symmetrical connecting plate 27, various raw materials such as acrylamide monomer, initiator, chain transfer agent and deionized water can be fed in equal proportion. When equal proportion feeding is required, it will be more convenient and efficient. After the raw materials inside the kettle body 1 are mixed, the valve 6 is opened to discharge the materials through the discharge pipe 5.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
