[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 3 , the utility model provides an embodiment: an intermittent polybutene reactor with external cooling, comprising a base 1, a support platform 2 is fixedly connected to the upper surface of the base 1, a motor 3 is fixedly connected to the inside of the support platform 2, a rotating shaft 4 is fixedly connected to the output end of the motor 3, a stirring blade 5 is fixedly connected to the outer wall of the rotating shaft 4, a fixing plate 6 is rotatably connected to the outer wall of the rotating shaft 4, a main gear 7 is fixedly connected to the outer wall of the rotating shaft 4, a barrel body 8 is fixedly connected to the upper surface of the base 1, a gear ring 9 is fixedly connected to the inside of the barrel body 8, a sub-gear 10 is arranged inside the gear ring 9, the main gear 7 is meshed with the sub-gear 10, the gear ring 9 is meshed with the sub-gear 10, the sub-gear 10 is rotatably connected to the outer wall of the fixing plate 6, the sub-gear 10 is rotatably connected to the outer wall of the fixing plate 6, the fixing seat 11 is rotatably connected to the inside of the fixing seat 11, a stirring rod 12 is fixedly connected to the inside of the fixing seat 11, a connecting plate 13 is rotatably connected to the outer wall of the stirring rod 12, a scraper 14 is fixedly connected to the lower surface of the connecting plate 13, and an observation component is arranged inside the barrel body 8;

[0023] Specifically, the motor 3 is used to drive the rotating shaft 4 to rotate. In this way, not only the stirring blade 5 fixed on the outer wall of the rotating shaft 4 can rotate to perform preliminary stirring, but also the main gear 7 fixed on the rotating shaft 4 will rotate accordingly. The meshing relationship between the main gear 7 and the sub-gear 10 enables the sub-gear 10 to move with the rotation of the rotating shaft 4. The sub-gear 10 and the gear ring 9 are meshed with each other, and the fixed plate 6 plays a role in limiting the position of the sub-gear 10, ensuring the stability of stirring. The sub-gear 10 is connected to the fixing seat 11 inside. When the rotating shaft 4 rotates, the fixing seat 11 can drive the stirring rod 12 to rotate on the inner wall of the barrel 8. In this way, the stirring rod 12 can stir the material inside the barrel 8 in an all-round manner, so that the material is evenly distributed inside the barrel 8. The stirring rod 12 is connected to the scraper 14 through the connecting plate 13. The scraper 14 contacts the bottom of the barrel 8. When the stirring rod 12 rotates, the scraper 14 can effectively stir the bottom of the barrel 8. This makes the stirring process more thorough and greatly improves the efficiency of the reactor. At the same time, it not only improves the efficiency of the reaction, but also speeds up the reaction rate.

[0024] Reference Figure 1-Figure 2 The observation assembly includes a first top cover 26, the outer wall of the first top cover 26 is fixedly connected to the inside of the barrel body 8, the outer wall of the first top cover 26 is fixedly connected to a hinge 27, the outer wall of the hinge 27 is fixedly connected to a second top cover 28, the upper surface of the second top cover 28 is fixedly connected to a handle 29, and the outer wall of the second top cover 28 is slidably connected to the inside of the barrel body 8;

[0025] Specifically, by pulling the handle 29 to drive the second top cover 28 to rotate around the hinge 27, the interior of the barrel body 8 can be opened. At the same time, the first top cover 26 can provide certain support to the second top cover 28, thereby achieving the effect of being able to observe the interior of the barrel body 8.

[0026] Reference Figure 1-Figure 3 , a fan 15 is fixedly connected to the bottom of the outer wall of the barrel body 8, and an air duct 16 is fixedly connected to the output end of the fan 15; a cooling box 17 is fixedly connected to the outer wall of the cooling box 17, and the outer wall of the cooling box 17 is fixedly connected to the outer wall of the barrel body 8, and a cooling plate 18 is arranged inside the cooling box 17; an air vent 19 is fixedly connected to the outer wall of the air vent 19, and a nozzle 20 is fixedly connected to the outer wall of the nozzle 20, and the outer wall of the nozzle 20 passes through the interior of the first top cover 26; an air outlet pipe 21 is fixedly connected to the outer wall of the air duct 16, and an air guide groove 22 is provided inside the barrel body 8; a cooling pipe 23 is fixedly connected to the inside of the barrel body 8, one end of the cooling pipe 23 is fixedly connected to the water inlet pipe 24, and the other end of the cooling pipe 23 is fixedly connected to the water outlet pipe 25; the outer walls of the water inlet pipe 24 and the water outlet pipe 25 both pass through the interior of the barrel body 8;

[0027] Specifically, when the temperature inside the reactor needs to be adjusted, the fan 15 will send cold air to the vent 19 through the air duct 16. In this process, the air duct 16 will pass through the cooling box 17, so that the cooling plate 18 can be used to cool the blown air. The cooled cold air is then sprayed into the interior of the reactor through the nozzle 20. In this way, the temperature inside the reactor can be effectively controlled, avoiding the influence of too high or too low temperature on the reaction process. At the same time, this method can also reduce the reaction time, further reduce production costs, and improve product quality. In addition, the air outlet 21 fixed on the outer wall of the air duct 16 can transport part of the cold air to the air guide groove 22. A cooling pipe 23 is fixed inside the air guide groove 22, and the cooling water in the cooling pipe 23 absorbs the cold air to reduce its temperature. This ensures the stability of the temperature inside the reactor. Thereby not only improving production efficiency, but also effectively reducing energy consumption, further reducing production costs.

[0028] Working principle: When it is necessary to fully stir the material inside the barrel body 8, the output end of the motor 3 drives the shaft 4 to rotate, so that the stirring blades 5, the fixing plate 6 and the main gear 7 fixed on the outer wall of the shaft 4 can rotate at the same time, so that the stirring blades 5 can preliminarily stir the inside of the barrel body 8, and then the main gear 7 is also fixed on the shaft 4, and at the same time the main gear 7 and the sub-gear 10 are meshed with each other, and the sub-gear 10 and the gear ring 9 are also meshed with each other, so that the shaft 4 can drive the sub-gear 10 to rotate inside the gear ring 9, wherein the fixing plate 6 can limit the position of the sub-gear 10, and then the sub-gear 10 is connected to the fixing seat 11 inside, so that the fixing seat 11 can drive the stirring rod 12 to rotate on the inner wall of the barrel body 8, thereby stirring the inside of the barrel body 8, and then the stirring rod 12 is connected by the connecting plate 13 The scraper 14 allows the scraper 14 to stir the bottom of the barrel body 8, so as to achieve the effect of fully stirring and accelerating the reaction of the internal materials, improve the efficiency of the reactor, and accelerate the reaction rate. When the temperature inside the barrel body 8 needs to be regulated, air is blown from the air duct 16 to the air vent 19 through the fan 15. When the air duct 16 passes through the cooling box 17, it can be cooled by the cooling plate 18, and then the cold air is sprayed into the interior of the barrel body 8 through the nozzle 20. At the same time, the air outlet 21 fixed on the outer wall of the air duct 16 can input part of the cold air into the air guide groove 22, and the cooling pipe 23 is fixed in the air guide groove 22, so that the cold air can cool the cooling water inside the cooling pipe 23, thereby achieving the effect of controlling the temperature inside the working reactor, shortening the reaction time, reducing costs and stabilizing quality.
