[0015] 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.

[0016] like Figure 1-4 As shown, this utility model provides a concentration and crystallization device for producing animal feed additives, including a crystallization kettle body 1, a stirring and cleaning mechanism 2 is provided inside the crystallization kettle body 1, a heating mechanism 3 is provided outside the crystallization kettle body 1, and a vacuum mechanism 4 is provided on the top of the crystallization kettle body 1. The stirring and cleaning mechanism 2 includes a stirring shaft 201. Three connecting rings 202 are fixedly connected at equal intervals to the outer wall of the stirring shaft 201. Multiple mounting grooves are equally spaced inside each connecting ring 202. Two connecting rings 202 can be detachably installed to the same stirring blade 203 via these mounting grooves. A connecting shaft 204 is fixedly connected to the outer wall of the connecting rings 202. One end of the connecting shaft 204 is fixedly connected to the corresponding side of the cleaning plate 205. The top end of the stirring shaft 201 passes through the crystallization vessel body 1 and is connected to the output end of a motor 206. The motor 206 is fixedly connected to the crystallization vessel body. At the top of unit 1, a stirring and cleaning mechanism 2, a heating mechanism 3, and a vacuum mechanism 4 are installed. This allows the concentration and crystallization device to use a jacketed heating system 301 combined with anchor stirring to ensure uniform heating of the material and avoid local overheating. At the same time, the stirring can effectively scrape the wall, promote heat and mass transfer, increase the concentration speed, and make the crystal particle size distribution more uniform. The cleaning plate 205 can continuously scrape the vessel wall, effectively inhibiting the deposition and scaling of crystals on the heated wall surface, ensuring the stability and heat transfer efficiency of long-term operation. Meanwhile, concentration and crystallization under vacuum conditions lowers the boiling point of the material and reduces heat energy consumption.

[0017] The heating mechanism 3 includes a jacket 301, which is fixedly connected to the outer wall of the crystallizing vessel body 1. The jacket 301 has a cavity inside. A heating medium input device 302 is provided at the bottom of the jacket 301, and a heating medium output device 303 is provided at the top of the jacket 301. By setting the jacket 301, the material is heated evenly, and local overheating is avoided.

[0018] The vacuum mechanism 4 includes a vacuum pump 401 connected to the top of the crystallization vessel body 1 via a pipe 402, and a condenser installed on the pipe 402. By setting up the vacuum mechanism 4 and connecting it to the top of the crystallization vessel body 1 via the pipe 402, it is used to maintain a negative pressure environment inside the crystallization vessel body 1 and reduce the evaporation temperature.

[0019] The inner wall of the crystallization vessel body 1 is provided with a stainless steel liner 5 polished to a mirror finish. The outer wall of the cleaning plate 205 is in contact with the inner wall of the crystallization vessel body 1. By providing the stainless steel liner 5, the adhesion of the inner wall of the crystallization vessel body 1 can be reduced, making it easier for the cleaning plate 205 to clean the inner wall of the crystallization vessel body 1. At the same time, the mirror-polished inner wall reduces the crystal adhesion points. Combined with uniform stirring and temperature control, it is beneficial to obtain crystal products with regular morphology and high purity.

[0020] The crystallization vessel body 1 is equipped with a feed pipe 6 at the top and a discharge pipe 7 at the bottom. A crystal slurry pump 8 is installed outside the discharge pipe 7, and a centrifuge is installed at one end of the discharge pipe 7. By setting up the crystal slurry pump 8 and the centrifuge, solid-liquid separation can be carried out quickly, thereby quickly obtaining crystal particles.

[0021] A bearing seat 10 is fixedly connected to the top of the inner wall of the crystallization vessel body 1. A bearing 9 is installed inside the bearing seat 10. The bearing seat 10 is rotatably connected to the stirring shaft 201 through the bearing 9. By setting the bearing seat 10 and the bearing 9, the stirring shaft 201 can be supported during rotation, ensuring the stability of the stirring shaft 201 rotation. At the same time, it can also reduce the friction generated when the stirring shaft 201 rotates, ensuring the efficiency of the stirring shaft 201 rotation and avoiding the situation of rotation jamming.

[0022] Working principle: During operation, the feed additive solution is added to the crystallization vessel body 1 through the feed pipe 6. The jacket 301 is heated by a heat medium, and the vacuum pump 401 is started to reduce the pressure of the system. The material is rapidly evaporated and concentrated at low temperature. The drive motor 206 drives the anchor stirring shaft 201 to rotate at a uniform speed, so that the material is heated evenly and the crystal scaling is inhibited. When the predetermined concentration is reached, the system enters the crystallization stage, inducing the uniform precipitation and growth of crystals. The mature crystal slurry is discharged from the bottom discharge pipe 7 and transported to the centrifuge by the crystal slurry pump 8 for solid-liquid separation to obtain the feed additive crystal product.

[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
