[0023] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] like Figure 1 As shown, an embodiment of the present invention provides an ion exchange device 100, which includes a shell 10, a guide tube 20 and an air supply pipe 30. A cavity 11 is provided in the shell 10, an inlet 12 and an exhaust port 13 are provided at the top of the shell 10, and an outlet 14 is provided at the bottom of the shell 10. The inlet 12, the exhaust port 13 and the outlet 14 are all connected to the cavity 11; the guide tube 20 is provided in the cavity 11, and both ends of the guide tube 20 are open; the end of the air supply pipe 30 passes through the shell 10 and the guide tube 20 in sequence along the left and right directions of the guide tube 20 and extends into the guide tube 20. The air supply pipe 30 has a first extension section 31 located in the guide tube 20, and the first extension section 31 extends from top to bottom along the up and down directions of the guide tube 20. An air outlet 32 is provided on the first extension section 31.

[0025] Specifically, the inlet 12 allows materials to enter the cavity 11, and the outlet 14 allows materials to be discharged from the cavity 11. In addition, the inlet 12 is provided at the top of the housing 10, and the outlet 14 is provided at the bottom of the housing 10, so that the material can flow from the inlet 12 to the outlet 14 by its own gravity, thereby realizing the circulation of the material in the cavity 11.

[0026] Secondly, the end of the air supply pipe 30 passes through the housing 10 and the guide tube 20 in sequence along the left-right direction of the guide tube 20 and enters the guide tube 20. That is, the air supply pipe 30 enters the guide tube 20 from the side of the equipment. This not only minimizes the space occupied by the air supply pipe 30 in the guide tube 20, ensuring unimpeded material flow, but also avoids the air supply pipe 30 obstructing the material flow path compared to directly inserting the air supply pipe 30 into the guide tube 20 from above. In addition, the first extension section 31 of the air supply pipe 30 extends from top to bottom within the guide tube 20 along the vertical direction of the guide tube 20, thereby reducing the risk of material blocking the air outlet 32, helping to improve operational safety and ensure the normal operation of the equipment.

[0027] During use of the ion exchange device 100 provided in the embodiment of the present invention, material is first introduced into the cavity 11 through the inlet 12 at the top of the housing 10. As the air supply pipe 30 is activated, the air outlet 32 begins to eject air, which forms a power source within the guide tube 20, driving the surrounding material upward and fully mixing with the airflow. Driven by the airflow, the material continuously leaps, rolls, collides, and contacts, thereby achieving an efficient ion exchange reaction, until it merges with the material outside the guide tube 20 at the upper end of the guide tube 20, and the airflow overflows into the cavity 11 through the exhaust port 13.

[0028] Moreover, when the air flow is ejected from the air outlet 32, a negative pressure area 22 can be formed between the air outlet 32 and the lower opening of the guide tube 20. Part of the logistics outside the guide tube 20 can enter the guide tube 20 from the lower opening of the guide tube 20, thereby realizing the circulation flow of materials inside and outside the guide tube 20, thereby accelerating the progress of the ion exchange reaction.

[0029] Furthermore, the first extension 31 of the air supply pipe 30 is disposed within the guide tube 20 from top to bottom along the vertical direction of the guide tube 20, such that the air outlet 32 faces the side wall or bottom of the guide tube 20. During material loading and equipment shutdown, the material can settle from the inlet 12 to the outlet 14 under its own gravity, preventing the material from entering the air supply pipe 30 through the air outlet 32. This prevents material from clogging the air supply pipe 30, thereby improving equipment operation safety.

[0030] In summary, in the ion exchange device 100 provided by the embodiment of the present invention, the air supply pipe 30 enters the guide tube 20 through the side of the guide tube 20 and is extended from top to bottom through the first extension section 31. This not only reduces the occupation of the air supply pipe 30 in the internal space of the guide tube 20, ensuring unimpeded flow of materials, but also prevents materials from clogging the air supply pipe 30, thereby improving the safety of equipment operation.

[0031] In this embodiment, the air supply pipe 30 includes a second extension section 33 connected to the first extension section 31. The second extension section 33 is arranged in an S-shaped curve within the cavity 11. Airflow within the air supply pipe 30 first enters the second extension section 33, passes through the cavity 11, and then enters the first extension section 31 and into the guide tube 20. This creates a more uniform and stable airflow, allowing for better mixing with the material within the guide tube 20 and promoting the ion exchange reaction.

[0032] Furthermore, the shell 10 has a first connection 15 connected to the second extension section 33, and the guide tube 20 has a second connection 21 connected to the second extension section 33. In the up and down directions of the guide tube 20, the first connection 15 is higher than the second connection 21, that is, there is a height difference between the two ends of the second extension section 33, so that the air supply pipe 30 forms a natural descending channel in the shell 10, which is conducive to maintaining a certain speed and pressure of the airflow during the injection process.

[0033] In this embodiment, at least a portion of the first extension section 31 is positioned along the axis of the guide tube 20, positioning the air outlet 32 along the axis. This helps form a more uniform and stable flow field within the guide tube 20, thereby promoting thorough mixing and contact between the material and the airflow. Compared to off-axis spraying methods, the spraying method provided by this utility model more effectively reduces airflow collisions and reflections on the inner wall of the guide tube 20, thereby reducing energy loss and improving airflow utilization efficiency.

[0034] In this embodiment, a gap is provided between the air outlet 32 and the lower open end of the guide tube 20 to form a negative pressure region 22 at the lower end of the guide tube 20. This allows materials outside the guide tube 20 to be continuously drawn into the guide tube 20 to participate in the ion exchange reaction, while the reacted materials are pushed out of the guide tube 20 from the upper end. This circular flow pattern not only accelerates the mixing and reaction between materials, but also improves the efficiency and uniformity of ion exchange.

[0035] In some embodiments, a side air port 311 is provided on the side wall of the first extension section 31, and the side air ports 311 are provided with at least two, thereby forming a multi-point injection and dispersion of the airflow, thereby avoiding the problem of excessive or weak local airflow that may be caused by single-point injection. Furthermore, the provision of the side air ports 311 also promotes the full mixing of the airflow and the material. In the guide tube 20, when the airflow is ejected through the air outlet 32 and the multiple side air ports 311, they will form multiple interwoven and colliding airflows inside the guide tube 20. These airflows continuously contact, mix and react with the material during the flow process, thereby accelerating the ion exchange process. At the same time, the interaction between the multiple airflows also promotes the relative movement and diffusion between the materials, further improving the mixing effect and reaction rate.

[0036] In some embodiments, the ion exchange device 100 further includes a bracket 40 disposed within the cavity 11. One end of the bracket 40 is connected to the housing 10, and the other end of the bracket 40 is connected to the flow tube 20. Specifically, one end of the bracket 40 can be welded, bolted, or otherwise connected with high strength to ensure a tight connection and stable support to the housing 10. The other end of the bracket 40 is precisely connected to a specific location of the flow tube 20, such as the top, middle, or other location determined as needed, to effectively support and position the flow tube 20.

[0037] Furthermore, the bracket 40 includes a first frame 41 and a second frame 42, which are positioned opposite each other at the ends of the guide tube 20, thereby forming a stable support structure, effectively preventing the guide tube 20 from deflecting or shaking due to uneven force, thereby ensuring stable operation of the equipment. Specifically, the first frame 41 is positioned at the upper end of the guide tube 20, and the second frame 42 is positioned at the lower end of the guide tube 20.

[0038] Furthermore, the guide tube 20 is arranged on the central axis of the cavity 11, thereby forming a centrally symmetrical layout, which helps to reduce the eddy and turbulent phenomena of the material in the cavity 11, so that the material can be more smoothly and evenly distributed in the entire cavity 11.

[0039] In some embodiments, a collecting surface 16 is provided at the bottom of the housing 10. The collecting surface 16 is configured to be lower in the middle and higher around the edges. The outlet 14 is located in the middle of the collecting surface 16, thereby facilitating the collection and discharge of materials from the outlet 14. Furthermore, when cleaning the equipment, technicians can more easily remove small amounts of impurities accumulated on the edges of the collecting surface 16, thereby maintaining cleanliness and efficient operation of the equipment.

[0040] like Figure 2 As shown, in some embodiments, the ion exchange device 100 further includes a first screen 51 and a second screen 52, which are disposed at opposite ends of the cavity 11, and a gap is provided between the first screen 51 and the second screen 52 and the end of the guide tube 20. The first screen 51 is disposed at the upper end of the cavity 11, and the second screen 52 is disposed at the lower end of the cavity 11.

[0041] Specifically, the first screen 51 and the second screen 52 are respectively located at the inlet 12 and outlet 14 ends of the cavity 11, and together constitute a barrier for the material to enter and leave the cavity 11, which helps to control the flow speed and direction of the material and prevent the material from disorderly accumulation or excessive diffusion in the cavity 11, thereby improving the efficiency and effect of ion exchange.

[0042] Furthermore, a certain gap is provided between the first screen 51 and the second screen 52 and the end of the guide tube 20, so that the material forms a certain buffer zone between the screen and the guide tube 20. The material in this zone can be continuously stirred and mixed with the rotation of the guide tube 20 or the action of the airflow. This stirring and mixing action helps the material to more fully exchange ions with the airflow, thereby improving the thoroughness and efficiency of the ion exchange.

[0043] The gap also prevents clogging of the screen. During the ion exchange process, the material may contain impurities or particles. If these materials come into direct contact with the screen surface, they can easily cause clogging. The presence of the gap allows these impurities or particles to flow away from the screen surface as the material flows, thus keeping the screen unobstructed.

[0044] In addition, the present invention also provides an ion exchange system, which includes the ion exchange device 100 of the above embodiment. The beneficial effects that can be achieved by the ion exchange system can refer to the corresponding beneficial effects of the ion exchange device 100 provided above, which will not be repeated here.

[0045] It should be noted that the ion exchange system also includes a feed device and a gas supply device. The feed device is connected to the inlet 12, and the gas supply device is connected to the gas supply pipe 30. The feed device may include a storage bin and a delivery pipeline, which can be connected to the inlet 12 to ensure that the material enters the cavity 11 at an appropriate flow rate and pressure, providing a sufficient and stable source of material for the subsequent ion exchange process. The gas supply device is connected to the gas supply pipe 30 to introduce fresh gas or gas with a specific composition into the cavity 11, providing the necessary power and medium for the ion exchange process.
