Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] Please refer to 1-2, an integrated synthesis reactor suitable for the synthesis of high-purity benzethonium chloride, including a cylinder 1, the inner wall of the cylinder 1 is opened into a curved surface with convex surfaces 11 and concave surfaces 12 arranged alternately, a stirring shaft 6 is rotatably arranged in the cylinder 1, and stirring blades 7 and axial flow stirrers 8 are alternately arranged on the stirring shaft 6, and a slider 71 is slidably arranged at both ends of the stirring blade 7, one end of the slider 71 extends into the stirring blade 7 and is connected to the inner wall of the stirring blade 7 through a spring 9, and the other end of the slider 71 is fixedly connected to a scraper 72, and the scraper 72 abuts against the inner wall of the cylinder 1.

[0024] Specifically, the retractable agitator is composed of a stirring blade 7, a slider 71, a scraper 72, a spring 9 and other accessories. One end of the spring 9 is fixedly connected to the inner wall of the stirring blade 7, and the other end of the spring 9 is fixedly connected to the slider 71. The utility model fixes the retractable agitator on the stirring shaft 6, cooperates with the convex surface 11 and the concave surface 12, and realizes the automatic extension and retraction of the retractable agitator, thereby achieving the purpose of improving the mixing efficiency at the edge of the inner wall of the reactor, thereby improving the reaction rate of the chemical reaction. At the same time, the scraper 72 that is tightly attached to the inner wall of the cylinder 1 is used to scrape the sticky solution on the inner wall of the cylinder 1 for mixing, thereby further increasing the mixing efficiency of the raw materials and accelerating the progress of the chemical reaction.

[0025] Furthermore, a spoiler plate 73 is fixedly sleeved on the slider 71 , and a plurality of through holes 731 are formed on the spoiler plate 73 .

[0026] Specifically, refer to Figure 1 When the stirring shaft 6 rotates, the scraper 72 closely attached to the inner wall of the cylinder 1 makes a circular motion along the convex surface 11 and the concave surface 12 in the cylinder 1. At this time, the scraper 72 drives the slider 71 to slide back and forth in the radial direction, so that the spoiler 73 fixedly sleeved on the slider 71 moves synchronously with the slider 71, so that the mixed solution in the cylinder 1 passes through the through hole 731, and then disturbs the mixed solution, thereby improving the mixing efficiency of the mixed solution.

[0027] Furthermore, a sealing ring 10 is provided inside the stirring blade 7 , and the sealing ring 10 is sleeved on the outer side of the sliding block 71 .

[0028] Specifically, refer to Figure 1The sealing ring 10 is a sliding sealing ring, which increases the sealing between the stirring blade 7 and the sliding block 71 to prevent the mixed solution from entering the stirring blade 7 and affecting the sliding of the sliding block 71 in the stirring blade 7.

[0029] Furthermore, both ends of the stirring blade 7 are provided with a choke blade 74 , and the end of the choke blade 74 is closely attached to the side surface of the sliding block 71 .

[0030] Specifically, refer to Figure 1 The choke blade 74 is fixedly connected to the end of the stirring blade 7. Through the setting of the choke blade 74, when the slider 71 retracts into the stirring blade 7, the sticky solution on the outside of the slider 71 is scraped off by the choke blade 74, thereby preventing the solution from entering the stirring blade 7.

[0031] Furthermore, the convex surface 11 and the concave surface 12 are rounded.

[0032] Specifically, refer to Figure 2 The convex surface 11 and the concave surface 12 are rounded to make the intersection of the convex surface 11 and the concave surface 12 smooth, thereby reducing the resistance of the scraper 72 when sliding on the inner wall of the cylinder 1, thereby improving the power conversion rate of the motor 4.

[0033] Furthermore, the stirring blades 7 and the axial flow agitator 8 are both fixedly sleeved on the stirring shaft 6, a cylinder cover 2 is provided on the top of the cylinder body 1, a feed port 13 and a pressure gauge 5 are provided on the top of the cylinder cover 2, a reducer 3 is provided on the top of the cylinder cover 2, a motor 4 is provided on the top of the reducer 3, and the stirring shaft 6 is driven by the motor 4.

[0034] Specifically, the feed port 13 is connected to the cylinder 1, and the feed port 13 is used to add raw materials into the cylinder 1. The pressure gauge 5 is used to monitor the pressure in the cylinder 1. After the pressure exceeds a certain value, the corresponding decompression treatment is performed. The speed of the motor 4 is reduced by the reducer 3 and then drives the stirring shaft 6 for stirring. The connection method between the output shaft of the motor 4, the reducer 3, and the stirring shaft 6 is common knowledge to the staff in this field and will not be explained in detail here.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
