It is a key raw material for the preparation of iodine contrast agents and some drugs for treating thyroid diseases, such as in the preparation of iodine contrast agents and as an analytical reagent. Traditional preparation methods mainly include the iron filings method and the sodium hydroxide method.
[0003] In traditional sodium iodide preparation material pretreatment processes, common stirring devices have simple structures and often can only stir in a single direction or at a limited angle. This results in incomplete mixing of materials within the reactor, easily leading to large local concentration differences. For example, some lumpy or sticky materials may clump together, making them difficult to disperse and mix evenly, affecting the subsequent reaction efficiency and product quality in sodium iodide preparation.
[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a material pretreatment device for sodium iodide preparation is proposed. Summary of the Invention

[0007] The stirring mechanism includes: a motor, which is fixedly connected to one side of the outer wall of the reactor; a transmission rod is rotatably connected to one side of the inner wall of the reactor; one end of the motor output shaft passes through the reactor and is fixedly connected to one end of the transmission rod; a first gear is rotatably connected to one side of the inner wall of the reactor; one side of the first gear is fixedly connected to the other end of the transmission rod; two transmission plates are provided on the circumferential inner wall of the reactor; two first stirring rods are fixedly connected between the two transmission plates; the circumferential outer wall of the transmission rod is movably connected to one of the transmission plates; and a through hole is opened on one side of the other transmission plate.
[0008] The inner circumferential wall of the through hole is fixedly connected with several tooth blocks. A second gear is provided in the through hole. One side of the second gear is rotatably connected to the inner wall of one side of the reactor. The outer circumferential wall of the first gear meshes with the outer circumferential wall of the second gear. The outer circumferential wall of the second gear meshes with several tooth blocks.

[0012] In a preferred embodiment of this utility model, two limiting grooves are formed on the inner circumferential wall of the reactor, and two limiting plates are slidably connected in each of the two limiting grooves.
[0013] In a preferred embodiment of this utility model, the two limiting plates are respectively fixedly connected to both sides of the transmission plate.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:
[0019] (1) This utility model provides a material pretreatment device for sodium iodide preparation. A motor drives a transmission rod, and the first gear on the transmission rod meshes with the second gear. The second gear meshes with the tooth block in the through hole, thereby causing the transmission plate to drive the first stirring rod to rotate. At the same time, in the reversing assembly on the transmission rod, the connecting plate drives the shearing rod to rotate, and the second stirring rod and the shearing rod are alternately distributed.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0028] like Figure 1 As shown, a material pretreatment device for sodium iodide preparation includes: a reaction vessel 1, and a stirring mechanism 5 disposed in the reaction vessel 1;
[0029] like Figures 1-3As shown, the stirring mechanism 5 includes: a motor 501, which is fixedly connected to the outer wall of one side of the reactor 1; a transmission rod 508 is rotatably connected to the inner wall of one side of the reactor 1; one end of the output shaft of the motor 501 passes through the reactor 1 and is fixedly connected to one end of the transmission rod 508; a first gear 512 is rotatably connected to the inner wall of one side of the reactor 1; one side of the first gear 512 is fixedly connected to the other end of the transmission rod 508; two transmission plates 504 are provided on the inner circumference of the reactor 1; two first stirring rods 506 are fixedly connected between the two transmission plates 504; the outer circumference of the transmission rod 508 is movably connected to one of the transmission plates 504; and a through hole 514 is opened on one side of the other transmission plate 504.
[0030] A number of toothed blocks 515 are fixedly connected to the inner circumference of the through hole 514. A second gear 513 is provided in the through hole 514. One side of the second gear 513 is rotatably connected to the inner wall of one side of the reactor 1. The outer circumference of the first gear 512 meshes with the outer circumference of the second gear 513. The outer circumference of the second gear 513 meshes with a number of toothed blocks 515. A reversing component is provided on the outer circumference of the transmission rod 508.
[0031] The reversing assembly includes: a connecting plate 509, which is fixedly connected to the outer circumference of the transmission rod 508. Several shearing rods 510 are fixedly connected to both sides of the connecting plate 509. Several second stirring rods 507 are fixedly connected to the opposite side of the two transmission plates 504. The connecting plate 509 is located between the two transmission plates 504. Several second stirring rods 507 and several shearing rods 510 are alternately distributed. Two limiting grooves 511 are opened on the inner circumference of the reactor 1. Two limiting plates 505 are slidably connected in both limiting grooves 511. The two limiting plates 505 are fixedly connected to both sides of the transmission plate 504 respectively.
[0032] It should be noted that the motor 501 drives the transmission rod 508 to rotate, and the meshing of the first gear 512 and the second gear 513, as well as the engagement of the second gear 513 and the tooth block 515, causes the transmission plate 504 to drive the first stirring rod 506 to rotate. Simultaneously, the connecting plate 509 in the reversing assembly drives the shearing rod 510 to rotate, and the second stirring rod 507 and the shearing rod 510 are alternately distributed. This multi-directional, multi-layered stirring method breaks up the agglomeration of materials, increases the contact area between materials, and ensures that the materials are thoroughly mixed within the reactor 1, effectively improving the uniformity and efficiency of material mixing. Through the setting of the limiting groove 511 and the limiting plate 505, during the stirring process, the limiting plate 505 slides within the limiting groove 511, limiting and guiding the transmission plate 504, preventing it from shaking or shifting during rotation. The reversing assembly enhances the shearing effect on the materials. The alternating distribution of the shearing rod 510 and the second stirring rod 507 creates relative motion during the stirring process, which generates shear force on the material. This further refines the material particles, breaks down the macromolecular structure in the material, promotes chemical reactions between materials, and improves the reactivity of the material, thereby enhancing the efficiency and quality of sodium iodide preparation.
[0033] like Figures 1-3 As shown, a protective shell 502 is fixedly connected to one side of the outer wall of the reactor 1. The motor 501 is located inside the protective shell 502. Several through heat dissipation grooves 503 are opened on the outer circumference of the protective shell 502. A feed hopper 2 is connected to the pipe on the outer circumference of the reactor 1. A discharge pipe 3 is connected to the pipe on the outer circumference of the reactor 1. A valve is installed in the discharge pipe 3. Several support rods 4 are fixedly connected to the outer circumference of the reactor 1.
[0034] It should be noted that the protective shell 502 provides protection for the motor 501, preventing damage from collisions with external objects, dust intrusion, and liquid splashes, thus extending the service life of the motor 501. The heat dissipation groove 503 ensures that the heat generated by the motor 501 during operation can be dissipated in a timely manner, preventing performance degradation or damage due to overheating, ensuring stable operation of the motor 501, and continuously providing power to the stirring mechanism 5. The feed hopper 2 facilitates the addition of various materials required for the preparation of sodium iodide into the reaction vessel 1. The discharge pipe 3, in conjunction with the valve settings, allows for control of the discharge of materials after the reaction according to actual production needs.
[0035] In use, the prepared materials are added to the reaction vessel 1 through the feed hopper 2. During stirring, the motor 501 is turned on, driving the transmission rod 508 to rotate. The first gear 512 on the transmission rod 508 rotates accordingly, meshing with the second gear 513, which in turn drives the second gear 513 to rotate. The second gear 513 then meshes with the toothed block 515 in the through hole 514, thereby causing the transmission plate 504 to drive the first stirring rod 506 and the second stirring rod 507 to start rotating. At the same time, the connecting plate 509 on the transmission rod 508 drives the shearing rod 510 to rotate. Since the second stirring rod 507 and the shearing rod 510 are alternately distributed, relative motion is formed during the stirring process, performing multi-directional and multi-layer stirring and shearing on the materials. When the materials are stirred evenly, the motor 501 is turned off, and stirring stops. The valve in the discharge pipe 3 is opened, allowing the pre-treated materials in the reaction vessel 1 to be discharged through the discharge pipe 3.
[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
