[0002] Chloroprene rubber is an important synthetic rubber with excellent oil resistance, heat resistance, aging resistance and mechanical properties. In the production process of modified chloroprene rubber, the reaction vessel is one of the key pieces of equipment. The existing chloroprene rubber reaction vessels are driven by a motor to rotate the stirring blades. However, the stirring blades can only rotate the chloroprene rubber slurry in one direction, resulting in poor stirring effect on the chloroprene rubber. This prevents the chloroprene rubber from reacting fully, resulting in a longer melting time and reducing the working efficiency of the reaction vessel. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1 This embodiment of a reaction vessel for producing modified chloroprene rubber includes a vessel body 1. The top of the vessel body 1 is provided with an inlet pipe 5 that communicates with the vessel body 1 to facilitate the entry of raw materials into the vessel body 1. The bottom of the vessel body 1 is connected to an outlet pipe 7 for discharging modified chloroprene rubber. A fixing plate 6 is horizontally provided on the inner wall of the vessel body 1. A stirring mechanism 3 is provided inside the vessel body 1 to stir the modified chloroprene rubber and improve the reaction rate of the modified chloroprene rubber.
[0020] Please see Figure 2 In this embodiment, the stirring mechanism 3 includes a motor 301 vertically disposed on the top wall of the inner body 1. The output shaft of the motor 301 is vertically provided with a first rotating rod 302. One end of the first rotating rod 302 is horizontally provided with a rotating plate 305. A second rotating rod 306 is rotatably disposed inside the rotating plate 305 through a bearing. One end of the first rotating rod 302 is provided with a first gear 303. One end of the second rotating rod 306 is provided with a second gear 304 that meshes with the first gear 303. Multiple stirring parts 307 are provided on the outer sides of both the first rotating rod 302 and the second rotating rod 306 for stirring the modified chloroprene rubber.
[0021] The stirring section 307 includes a first stirring rod 3071 and a second stirring rod 3072. A plurality of first stirring rods 3071 are horizontally arranged outside the first rotating rod 302 and the second rotating rod 306, and a plurality of second stirring rods 3072 are equidistantly distributed outside the first stirring rods 3071. The modified chloroprene rubber is stirred by the cooperation of the first stirring rods 3071 and the second stirring rods 3072, thereby increasing the stirring range and the reaction rate of the modified chloroprene rubber.
[0022] It also includes a heater 8 and a temperature monitor 9. The heater 8 and the temperature monitor 9 are respectively located at the left and right ends of the bottom of the vessel body 1. The heater 8 heats the modified chloroprene rubber inside the vessel body 1, and the temperature monitor 9 monitors the temperature inside the vessel body 1.
[0023] It also includes an anti-corrosion layer 2, which is set on the inner wall of the vessel body 1. The anti-corrosion layer 2 is an epoxy coal tar coating, which prevents the chloroprene rubber from corroding the vessel body 1 during the reaction process.
[0024] Understandably, motor 301 drives the first rotating rod 302 to rotate, which in turn drives the first gear 303 and rotating plate 305 to rotate together. When rotating plate 305 rotates, it drives the second rotating rod 306 to make a circular motion. When the first gear 303 rotates, it drives the second gear 304 and the second rotating rod 306 to rotate together. Through the rotation of the first rotating rod 302 and the second rotating rod 306, the first stirring rod 3071 and the second stirring rod 3072 are driven to rotate, which stirs the modified chloroprene rubber. The stirring range is larger, so that the raw materials react more fully and the reaction rate of modified chloroprene rubber in the reactor 1 is increased.
[0025] Please see Figure 3 In this embodiment, a cooling mechanism 4 is also included. The cooling mechanism 4 includes a water tank 401, a water pump 403, and a condenser 409 disposed on the top of the vessel body 1. Water is placed in the water tank 401, and the water is pumped out of the water tank 401 by the water pump 403. The water is cooled by the condenser 409 for subsequent use. A first water pipe 402 connects the input end of the water pump 403 and the water tank 401, and a second water pipe 402 is provided at the output end of the water pump 403 through a through hole at the top of the vessel body 1. Pipe 404 also includes a control valve 405 disposed on the inner wall of the vessel body 1. The input end of the control valve 405 is connected to the second water pipe 404, and the output end of the control valve 405 is provided with a third water pipe 406. The bottom of the third water pipe 406 is connected to a coil 407 for cooling the modified chloroprene rubber in the vessel body 1. The output end of the coil 407 is provided with a fourth water pipe 408 connected to the condenser 409. A fifth water pipe 410 is connected between the condenser 409 and the water tank 401.
[0026] It also includes a water inlet pipe 411, which is located at the top of one end of the water tank 401 to facilitate replenishment of the water tank 401.
[0027] Understandably, water from water tank 401 is pumped by water pump 403 to water pipe 402 and then to water pipe 404. The flow rate of the water is controlled by control valve 405. The water then enters coil 407 through water pipe 404 and water pipe 406 to cool the modified chloroprene rubber. The used water then enters condenser 409 through water pipe 408 for further cooling. The cooled water then enters water tank 401 through water pipe 410 for continued use. This process facilitates rapid cooling of the modified chloroprene rubber and makes it easy to remove the modified chloroprene rubber.
[0028] The working principle of the above embodiments is as follows:
[0029] (1) When it is necessary to stir the raw materials, start the motor 301. The motor 301 drives the first rotating rod 302 to rotate. The first rotating rod 302 drives the first gear 303 and the rotating plate 305 to rotate together. During the rotation of the rotating plate 305, it will drive the second rotating rod 306 to make a circular motion together. During the rotation of the first gear 303, it will drive the second gear 304 and the second rotating rod 306 to rotate together. Through the rotation of the first rotating rod 302 and the second rotating rod 306, the first stirring rod 3071 and the second stirring rod 3072 will rotate together to stir the modified chloroprene rubber. The stirring range is larger, so that the raw materials react more fully and the reaction rate of the modified chloroprene rubber in the reactor 1 is increased.
[0030] (2) Start the water pump 403 and control valve 405. The water pump 403 draws water from the water tank 401 through the first water pipe 402 and sends it to the second water pipe 404. The water flow rate is controlled by the control valve 405. The water enters the coil 407 through the second water pipe 404 and the third water pipe 406 to cool the modified chloroprene rubber. The water after use will enter the condenser 409 through the coil 407 and the fourth water pipe 408 for cooling. The cooled water enters the water tank 401 through the fifth water pipe 410 for continued use, which facilitates rapid cooling of the modified chloroprene rubber and facilitates the removal of the modified chloroprene rubber.
