Description

Technical Field

[0001] This invention relates to the field of salt production technology, specifically to an iodine-added drying system. Background Technology

[0002] Iodized salt is a national strategy for disease prevention through public health measures. Its core purpose is to prevent intellectual impairment and thyroid diseases caused by iodine deficiency. Iodized salt is the safest, most economical, and most effective way to prevent iodine deficiency disorders. Iodine is a key raw material for the synthesis of thyroid hormones and participates in metabolism, growth and development (especially fetal and infant brain development) and energy regulation. The human body cannot synthesize iodine on its own and must obtain it from the external environment.

[0003] In existing technologies, iodine is usually added to salt by spraying iodine solution. During the transportation of salt, some salt may not come into contact with the sprayed iodine solution, resulting in uneven mixing of the iodine solution and salt. Furthermore, after iodization, the salt is transported to a drying oven to remove moisture. However, when the salt is left to stand, while the moisture in the surface layer dries, the drying of the inner layer takes a long time, which can lead to low drying efficiency and yellowing of the surface salt. Summary of the Invention

[0010] In some embodiments, a flow meter and a liquid pulse valve are also provided on the pipeline connecting the iodine tank and the spraying component.

[0011] In some embodiments, the spraying component includes an annular liquid guide tube and a plurality of nozzles. The annular liquid guide tube is installed in the cavity and communicates with the iodine tank, and the plurality of nozzles are installed at intervals on the annular liquid guide tube.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0018] To address the technical problems of uneven mixing of iodine solution and salt, and low drying efficiency of moisture in the iodine solution in existing technologies, this solution provides an iodized drying system that ensures thorough mixing of iodine solution and salt, while also shortening the drying time of salt and improving salt production efficiency.

[0019] Please see Figures 1-7 , Figures 1-7 An iodine-adding drying system according to one embodiment of the present invention includes a cylinder 1, an iodine-adding mechanism 2, a drying mechanism 3, and a lifting mechanism 4. The cylinder 1 has a cavity inside, and the top of the cylinder 1 has a feeding end communicating with the cavity. The iodine-adding mechanism 2 includes a spray element 21, which is installed on the cylinder 1 and located at the top inner part of the cavity. The spray element 21 can spray iodine solution into the cavity. The drying mechanism 3 communicates with the cavity and can deliver hot air into the cavity. The lifting mechanism 4 is connected to the bottom of the cylinder 1 and passes through the cavity. The lifting mechanism 4 can lift the salt at the bottom of the cavity to the top inner part of the cavity and unload it into the cavity. The lifting mechanism 4 can also unload the salt in the cavity to the outside of the cylinder 1.

[0020] In actual use, salt is conveyed into the cavity through the feeding end. During the conveying process, iodine solution is intermittently sprayed into the cavity by the spraying component 21. When the salt in the cavity reaches a certain height, the lifting mechanism 4 is activated. The lifting mechanism 4 lifts the salt at the bottom of the cavity to the top of the cavity and discharges it into the cavity, so that the salt flows continuously in the cavity, ensuring that the salt and iodine solution are fully mixed. After mixing for a period of time, hot air is conveyed into the cavity through the drying mechanism 3. The hot air comes into contact with the continuously flowing salt, and the moisture in the salt can be quickly dried by the hot air.

[0021] It should be noted that the lifting mechanism 4 is not limited to a specific structure. In one embodiment, the lifting mechanism 4 includes a lifting cylinder 41, a rotating shaft 42, a first helical blade 43, and a forward and reverse motor 44. The lifting cylinder 41 is fixedly connected to the bottom of the cylinder 1 and one end extends into the cavity. The lifting cylinder 41 is provided with a feeding part 41a and a discharging part 41b that communicate with the inner bottom and inner top of the cavity, respectively. The other end of the lifting cylinder 41 extending to the outside of the cylinder 1 is also provided with a discharge part 41c. The rotating shaft 42 is rotatably installed inside the lifting cylinder 41. The first helical blade 43 is provided inside the lifting cylinder 41 and installed on the rotating shaft 42. The forward and reverse motor 44 is fixed to the other end of the lifting cylinder 41 and connected to one end of the rotating shaft 42.

[0022] It is understandable that when the unloading section 41c is closed, when the forward and reverse motor 44 drives the rotating shaft 42 to rotate in the forward direction, the salt that enters into the lifting cylinder 41 through the feeding section 41a can be lifted to a preset height by the first spiral blade 43 and discharged into the cavity through the discharge section 41b, thereby improving the fluidity of the salt in the cavity; wherein, the discharge section 41b consists of multiple discharge pipes spaced apart on the lifting cylinder 41.

[0023] When the unloading section 41c is opened, the forward and reverse motors 44 drive the rotating shaft 42 to rotate in the opposite direction. The salt that enters the lifting cylinder 41 through the feeding section 41a can be pushed to the unloading section 41c by the first spiral blades 43 and discharged from the unloading section 41c to the outside of the cylinder.

[0024] Based on the above scheme, in order to ensure that the salt can also be dried by contact with the hot airflow inside the lifting cylinder 41, a suction mechanism 5 is specifically included. The suction mechanism 5 includes a cover 51 and a suction component 52. The cover 51 is fixed to one end of the lifting cylinder 41. The inner diameter of the cover 51 gradually decreases towards the feeding end, and the cover 51 is connected to the suction component 52. The other end of the rotating shaft 42 passes through the lifting cylinder 41 and extends into the cover 51. The rotating shaft 42 is provided with an air guiding channel along the axial direction. The rotating shaft 42 is provided with a mesh area connected to the air guiding channel near the top of the lifting cylinder 41, and a filter membrane 421 is sleeved on the rotating shaft 42 corresponding to the mesh area.

[0025] It is understandable that by using the suction device 52 to extract air from the cover, a negative pressure space is formed inside the cover 51. At this time, the airflow in the lifting cylinder 41 will enter the air guide channel through the mesh area. After the negative pressure space is formed inside the lifting cylinder 41, the airflow in the cavity will enter the lifting cylinder 41 through the feeding part 41a, ensuring that the salt can also come into contact with the hot airflow inside the lifting cylinder 41, which can further shorten the drying time.

[0026] It should be noted that, in one embodiment, the drying mechanism 3 includes an air guide pipe 31, an air diffuser pipe 32, and a hot air blower 33. The air guide pipe 31 is fixedly sleeved on the lifting cylinder 41 and located between the feeding section and the discharging section. An annular cavity is formed between the air guide pipe 31 and the lifting cylinder 41. A plurality of air diffusers 32 are arranged along the radial direction of the cylinder 1 and communicate with the annular cavity. The hot air blower 33 is connected to the annular cavity and can deliver hot airflow to the annular cavity.

[0027] Preferably, the diffuser 32 is formed by welding a perforated plate, and the diffuser 32 is arranged along the circumference of the air guide 31 to ensure that the hot airflow can be evenly dispersed into the cavity.

[0028] Understandably, by delivering hot air into the annular cavity through the hot air blower 33, the hot air is kept at a stable temperature of around 100°C. The hot air is diffused into the cavity through multiple air diffusers 32, which ensures that the hot air is evenly dispersed in the cavity and increases the contact area between the salt particles and the hot air.

[0029] It should be noted that, in one embodiment, the iodine addition mechanism 2 further includes a liquid supply component 22, which includes an iodine solution tank 221, a liquid extraction component 222, and a heating component 223. The iodine solution tank 221 is connected to the spray component 21 via the liquid extraction component 222. The heating component 223 is installed on the iodine solution tank 221 and is used to heat the iodine solution in the iodine solution tank 221. A flow meter 224 and a liquid pulse valve 225 are also provided on the pipeline connecting the iodine solution tank 221 and the spray component 21.

[0030] Understandably, the iodine tank 221 is also equipped with a temperature sensor. The temperature sensor, heating element 223, flow meter 224, and liquid pulse valve 225 are all electrically connected to the controller. The heating element 223 heats the iodine solution to 40°C. The volume of iodine solution to be added is determined based on the mass of salt delivered into the cavity. The iodine solution is sprayed into the cavity intermittently to ensure that salt at different heights can come into contact with the iodine solution.

[0031] In addition, based on the above scheme, a stirring component is also included. The stirring component is installed on the iodine solution tank 221. The stirring component is not limited to a specific structure, as long as it can stir the iodine solution in the iodine solution tank 221. No other limitations are made here.

[0032] Preferably, in one embodiment, the spraying component 21 includes an annular liquid guide tube and a plurality of nozzles. The annular liquid guide tube is installed in the cavity and communicates with the iodine solution tank 221, and the plurality of nozzles are installed at intervals on the annular liquid guide tube.

[0033] In addition, based on the above scheme, in order to crush the salt blocks, a crushing mechanism 6 is specifically included. The crushing mechanism 6 is installed on the top of the cylinder 1 and connected to the feeding end. The crushing mechanism 6 can crush the salt blocks.

[0034] In one embodiment, the crushing mechanism 6 further includes a crushing cylinder 61, a guide pipe 62, a grinding head 63, and a reduction motor 64. The crushing cylinder 61 is installed on the top of the cylinder 1 and communicates with the feeding end. The guide pipe 62 is installed inside the crushing cylinder 61 and communicates with the feeding port at the top and the discharge port at the bottom of the crushing cylinder 61. The reduction motor 64 is installed at the bottom of the crushing cylinder 61, and the output end of the reduction motor 64 extends into the crushing cylinder 61 and connects with the grinding head 63. A grinding gap is formed between the grinding head 63 and the guide pipe 62.

[0035] It is understandable that the inner diameter of the grinding gap gradually increases towards the top of the cylinder 1. By driving the grinding head 63 to rotate through the reduction motor 64, the salt block in the grinding gap can be crushed. The bottom of the crushing cylinder 61 extends into the cylinder 1, and the bottom of the crushing cylinder 61 is provided with multiple discharge pipes along the circumference. The output end of the reduction motor 64 is also fixed with a second spiral blade 65, which corresponds to the discharge pipe.

[0036] Based on the above scheme, a crushing component 66 is also included. The crushing component 66 is installed on the crushing cylinder 61 and corresponds to the feed inlet of the crushing cylinder 61. The crushing component 66 includes a shaft, a servo motor and multiple plates. The shaft is rotatably installed inside the crushing cylinder 61. The servo motor is installed on the crushing cylinder 61 and connected to one end of the shaft. Multiple plates are installed on the shaft circumferentially. The servo motor drives the shaft to rotate, thereby driving the plates to rotate. When the plates rotate at high speed, they can crush the salt blocks.

[0037] In addition, based on the above solution, in order to ensure uniform particle size of salt, in one embodiment, a screening mechanism 7 is also included. The screening mechanism 7 includes a screening cylinder 71 and a vibrating element 72. The screening cylinder 71 is movably installed in the cavity via multiple elastic elements and is connected to the feeding end. The vibrating element 72 is installed on the cylinder 1 and abuts against the screening cylinder 71. The vibrating element 72 can drive the screening cylinder 71 to vibrate.

[0038] It is understood that the screening cylinder 71 is provided with a connecting ring block on its periphery, and the connecting ring block is connected to the elastic element. The screening cylinder 71 has a screening area inside. The vibrating element 72 includes multiple drive motors 721 fixed to the outside of the cylinder. The output end of the drive motor 721 extends into the cavity and is fixed to the cam 722. The cam 722 supports the connecting ring block. By driving the cam 722 to rotate through the drive motor 721, the screening cylinder 71 can be driven to vibrate up and down.

[0039] In addition, in one embodiment, the top of the cylinder is provided with at least one cleaning port, and a hidden door is provided corresponding to the cleaning port. The hidden door can close or open the cleaning port, so that the operator can clean the larger salt particles inside the screening cylinder 71.

[0040] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
