It can usually be used as a hemostatic agent, drug carrier, tissue engineering material, etc. Its preparation principle is to react alginic acid solid with sodium hydroxide liquid to generate sodium alginate. In this process, a neutralization reaction device is usually required to provide a reaction container for the alginic acid solid and sodium hydroxide liquid.

[0003] Existing technologies such as the utility model with the publication number of CN215028791U disclose a neutralization reaction device for sodium alginate production.

The stirring paddle fits with the bottom of the tank body and is close to the bottom of the tank body. There are a plurality of second stirring blades extending vertically upward on the stirring paddle. The utility model adopts a stirrer with two different stirring blades. The first stirring blade realizes the stirring in the middle of the tank body, and the second stirring blade realizes the stirring at the bottom of the tank body.

[0039] Working principle: When using the neutralization reaction equipment for sodium alginate production to prepare sodium alginate, first, the production raw materials are added through the alginic acid metering tank 3, sodium hydroxide metering tank 4, and alcohol solution metering tank 5. Then, water is injected into the tank body 1 through the water inlet pipe 6. After that, the neutralization reaction equipment for sodium alginate production is connected to an external power source, and the motor 71 of the stirring mechanism 7 is started, so as to control the rotation of the rotating rod 72. The rotation of the rotating rod 72 causes the first stirring rod 73 and the second stirring rod 74 to stir the raw materials in the tank body 1, promoting the mixing of the raw materials. After the sodium alginate is prepared, the sodium alginate can be collected through the discharge pipe 2. During the preparation process of sodium alginate, the electric telescopic rod 83 is started to slide on the inner wall of the stabilizing plate 84. At this time, the electric telescopic rod 83 drives the connecting plate 82 and the connecting ring 81, thereby controlling the lifting of the motor 71 and the rotating rod 72, making the first stirring rod 73 and the second stirring rod 74 lift inside the tank body 1, thus promoting the mixing of the raw materials. When the motor 71 is lifted, the mounting plate 88 drives the limiting plate 89 to slide on the inner wall of the sleeve plate 87. By setting the mounting plate 88 and the sleeve plate 87, the motor 71 can be installed while ensuring that the motor 71 can be lifted. By setting the fixing plate 85 and the rectangular plate 86, the electric telescopic rod 83 can be installed and fixed. By setting the lifting device 8, when using the neutralization reaction equipment for sodium alginate production to prepare sodium alginate, the first stirring rod 73 and the second stirring rod 74 can be controlled to lift, so as to improve the stirring and mixing efficiency of the sodium alginate raw materials as much as possible.

[0040] When taking out the prepared sodium alginate, the rotation of the rotating rod 72 drives the fixed ring 91 and the first connecting rod 92 to rotate synchronously, driving the scraping rod 94 to scrape on the inner wall of the tank body 1, so as to avoid as much as possible that the prepared sodium alginate adheres to the inner wall of the tank body 1. By setting the limiting ring 98 and the second connecting rod 97, the connection stability of the scraping rod 94 can be ensured as much as possible. By setting the sliding rod 93, the sliding plate 95, and the spring 96, the scraping rod 94 can move closer to or away from the rotating rod 72, avoiding as much as possible that the residual sodium alginate affects the first connecting rod 92 and the second connecting rod 97 through the scraping rod 94, thus affecting the rotation of the rotating rod 72. By setting the cleaning device 9, after the sodium alginate production is completed using the neutralization reaction equipment for sodium alginate production, it is convenient to take out the sodium alginate in the tank body 1, and at the same time, avoid as much as possible that there is sodium alginate remaining on the inner wall of the tank body 1.
