Description

Technical Field

[0001] This application relates to the field of ion exchange technology, and in particular to an ion exchange device and a continuous moving bed. Background Technology

[0002] Ion exchange technology is a completely innovative separation process technology. It was developed by combining the advantages of continuous countercurrent system technology with the traditional fixed-bed resin adsorption and ion exchange processes. It consists of a disc with multiple resin columns and a porous distribution valve. By rotating the disc and switching the valve orifices, the separation column completes the entire process of adsorption, washing, desorption, and regeneration in one process cycle.

[0003] Because the weight of a single separation column is usually large, the stability of the separation column is poor during rotation, which can easily affect the ion exchange effect and damage the separation column. Utility Model Content

[0004] Therefore, it is necessary to provide an ion exchange device and a continuous moving bed to address the problem of poor stability of the separation column during rotation.

The multiple support columns are spaced apart along the circumferential direction of the rotating disk, and the rotating disk abuts against the rollers and makes rolling contact with the rollers.

[0013] In one embodiment, the roller is movably disposed on the support column.

[0014] In one embodiment, the outer peripheral surface of the driving wheel has a plurality of first teeth, and the outer peripheral surface of the driven wheel has a plurality of second teeth, wherein both the first teeth and the second teeth mesh with the transmission chain.

[0015] In one embodiment, the ion exchange device further includes a drive module that is tractively connected to the drive wheel and is used to output power to the drive wheel.

[0016] A continuous moving bed, the continuous moving bed comprising:

[0017] At least one ion exchange device as described in any of the above technical solutions.

[0018] In the aforementioned ion exchange device and continuous moving bed, the driving wheel outputs power to the driven wheel via a transmission chain. The driven wheel then drives the rotating disk to rotate, and the rotating ion column performs ion exchange on the internal material through the adsorbent. The sprocket transmission method involving the driving wheel, driven wheel, and transmission chain improves the stability of the power output from the driving wheel to the driven wheel, ensuring the stability of the ion column during rotation, improving the ion exchange effect of the ion exchange device, and reducing damage to the ion column.

[0031] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0032] See Figure 1 and Figure 2 As shown, this application provides an ion exchange device 100, which includes an ion column 110 and a rotating assembly 130. The ion column 110 is filled with an adsorbent for ion exchange reactions. If the ion column 110 is a hollow cavity, the adsorbent can be filled inside the ion column 110. The adsorbent can include, but is not limited to, adsorbent materials such as resin and activated carbon. Ion exchange operations can be performed inside the ion column 110 through the adsorbent. The ion column 110 is provided with a rotating disk 120. In this embodiment, the rotating disk 120 is detachably connected to one side of the bottom of the ion column 110 by means of screws, snap-fits, etc., to adapt to the installation requirements of ion columns 110 of different specifications. The rotating disk 120 drives the ion column 110 to rotate, so as to fully mix the material and adsorbent inside the ion column 110 and perform ion exchange operations. The rotating disk 120 is made of high-quality carbon structural steel profiles to ensure the rigidity of the rotating disk 120 during rotation, and an anti-rust layer is provided on the surface of the rotating disk 120 to extend the service life of the rotating disk 120.

[0033] The rotating assembly 130 includes a driving wheel 131, a driven wheel 132, and a transmission chain 133. The transmission chain 133 is wound around both the driving wheel 131 and the driven wheel 132. If the transmission chain 133 is a ring chain structure, the inner sides of both ends of the transmission chain 133 are respectively provided with the driving wheel 131 and the driven wheel 132. The driven wheel 132 is connected to the rotating disk 120 and is used to drive the rotation of the rotating disk 120. Specifically, the driving wheel 131 outputs power to the driven wheel 132 through the transmission chain 133, and the driven wheel 132 drives the rotating disk 120 to rotate. The rotation of the ion column 110 allows the adsorbent to perform ion exchange on the materials inside. The transmission chain 133 is a bent roller chain. The transmission chain 133 has no distinction between inner and outer links, and the transmission chain 133 has advantages such as excellent elasticity, good impact resistance, and uniform link pitch even after wear, which can ensure the stability of the power output transmitted from the driving wheel 131 to the driven wheel 132. Furthermore, the driving wheel 131 and the driven wheel 132 are made of alloy structural steel to improve the overall structural strength and wear resistance of the driving wheel 131 and the driven wheel 132, thereby improving the structural stability of the driving wheel 131 and the driven wheel 132 during long-term power transmission and ensuring the stability of the power output transmitted from the driving wheel 131 to the driven wheel 132.

[0034] The aforementioned ion exchange device 100, through the sprocket transmission method of the driving wheel 131, driven wheel 132 and transmission chain 133, can improve the stability of the power output from the driving wheel 131 to the driven wheel 132, thereby ensuring the stability of the ion column 110 during rotation, improving the ion exchange effect of the ion exchange device 100, and preventing the ion column 110 from being affected by tilting, stress concentration or other factors during operation, thus reducing damage to the ion column 110.

[0035] During long-term operation, the tension of the transmission chain 133 may change due to wear, variations in operating conditions, and other factors, leading to poor power transmission stability. Therefore, in one embodiment, see [reference needed]. Figure 1 and Figure 2 As shown, the ion exchange device 100 also includes a fixed support 140 and at least one tensioning component 150. The tensioning component 150 is movably disposed on the fixed support 140 and is used to adjust the tension of the transmission chain 133. The fixed support 140 is manufactured using high-quality carbon structural steel and has a reinforcing structure to improve its overall structural strength and stability. Thus, by changing the position of the tensioning component 150 relative to the fixed support 140, the tension of the transmission chain 133 can be adjusted, meeting the transmission requirements under different operating conditions and improving the stability of the power output transmitted from the driving wheel 131 to the driven wheel 132.

[0036] Specifically, see Figure 1and Figure 2 As shown, the tensioning assembly 150 includes a fixed base 151 and a tensioning wheel 152. The fixed base 151 is movably mounted on the fixed bracket 140, and the tensioning wheel 152 is mounted on the fixed base 151, engaging with the transmission chain 133. Thus, by moving the tensioning wheel 152 within the fixed bracket 140, the transmission chain 133 expands outward or contracts inward, or the tensioning wheel 152 changes its engagement position with the transmission chain 133, thereby adjusting the tension of the transmission chain 133. This prevents the transmission chain 133 from becoming too loose or too tight during transmission, meeting the transmission requirements under different working conditions and improving the stability of the power output transmitted from the driving wheel 131 to the driven wheel 132.

[0037] It should be noted that in this embodiment, the tensioning wheel 152 has teeth on its periphery, which enable the tensioning wheel 152 to mesh with the transmission chain 133. This allows for adjustment of the tension of the transmission chain 133 without affecting its power transmission. Furthermore, the fixing seat 151 can be detachably mounted on the fixing bracket 140 via screws. By locking the fixing seat 151 to different positions on the fixing bracket 140, the position of the tensioning wheel 152 can be adjusted.

[0038] Further, see Figure 1 and Figure 2 As shown, there are multiple tensioning components 150, which are spaced apart along the circumferential direction of the transmission chain 133. For example, as... Figure 2 As shown, there are two tensioning components 150, which are located on the upper and lower sides of the transmission chain 133, respectively. Of course, in other feasible embodiments, there may be three, four or other numbers of tensioning components 150. This application does not limit the specific number of tensioning components 150.

[0039] The aforementioned ion exchange device 100 can adjust the tension of the transmission chain 133 through multiple tensioning components 150. The multiple tensioning components 150 are spaced apart along the circumferential direction of the transmission chain 133, which facilitates the adjustment of the tension of the transmission chain 133 in multiple different directions. After adjustment, the tension of the transmission chain 133 in each direction tends to be consistent, which can ensure the stability of the transmission chain 133 during power transmission.

[0040] In one embodiment, see Figures 1-3As shown, the ion exchange apparatus 100 also includes a support assembly 160. The support assembly 160 supports the rotating disk 120 and is in rolling contact with the rotating disk 120. Thus, by supporting the rotating disk 120 with the support assembly 160, the stability of the rotating disk 120 during rotation is ensured, improving the ion exchange effect of the ion exchange apparatus 100 and reducing damage to the ion column 110. Furthermore, the rolling contact between the support assembly 160 and the rotating disk 120 ensures low-pair contact, reducing wear on the rotating disk 120 and improving the smoothness of rotation. Additionally, the support assembly 160 does not interfere with the rotation of the rotating disk 120.

[0041] Specifically, see Figures 1-3 As shown, the support assembly 160 includes multiple support columns 161 and rollers 162. The multiple support columns 161 are spaced apart along the circumferential direction of the rotating disk 120 to ensure the stability of the support provided by the multiple support columns 161 to the rotating disk 120. Rollers 162 are disposed on one end of the support columns 161, and the rotating disk 120 abuts against the rollers 162, with the rotating disk 120 and rollers 162 in rolling contact. Thus, the rollers 162 and the rotating disk 120 have low-pair contact, reducing wear on the rotating disk 120 caused by the rollers 162 and improving the smoothness of the rotation of the rotating disk 120, while ensuring that the rollers 162 do not interfere with the rotation of the rotating disk 120.

[0042] In this embodiment, the support column 161 is manufactured by welding high-quality carbon structural steel profiles to ensure that the support column 161 has sufficient rigidity to stably support the rotating disk 120. Furthermore, the surface of the support column 161 is provided with an anti-rust layer to extend its service life. Additionally, the roller 162 is a polyurethane component, possessing advantages such as high strength, high hardness, high wear resistance, excellent elasticity, and excellent anti-aging properties, enabling it to withstand the rolling wear of the rotating disk 120 over extended periods.

[0043] Further, see Figures 1-3 As shown, roller 162 is movably mounted on support column 161. Thus, since the rotating disk 120 abuts against roller 162, by adjusting the connection position between roller 162 and support column 161, the height of roller 162 is changed, thereby adjusting the levelness of rotating disk 120, improving the rotational balance of rotating disk 120 during rotation, improving the ion exchange effect of ion exchange device 100, and reducing damage to ion column 110.

[0044] In one embodiment, see Figure 1 and Figure 2As shown, the outer circumferential surface of the driving wheel 131 has multiple first gear teeth 1311, and the outer circumferential surface of the driven wheel 132 has multiple second gear teeth 1321. Both the first gear teeth 1311 and the second gear teeth 1321 are engaged with the transmission chain 133. Thus, the driving wheel 131 is engaged with the transmission chain 133 through the first gear teeth 1311, and the driven wheel 132 is engaged with the transmission chain 133 through the second gear teeth 1321. The first gear teeth 1311 and the second gear teeth 1321 are dynamically engaged with the transmission chain 133. The driving wheel 131 can output power to the driven wheel 132 through the transmission chain 133. The driven wheel 132 drives the rotating disk 120 to rotate, and the rotating disk 120 drives the ion column 110 to rotate, completing the ion exchange operation of the adsorbent on the material inside the ion column 110.

[0045] Further, see Figure 1 and Figure 2 As shown, the ion exchange device 100 also includes a drive module. The drive module is driven to the drive wheel 131 and is used to output power to the drive wheel 131. For example, if the drive module has an output end, the output end of the drive module is connected to the drive wheel 131. The drive module can output power to the drive wheel 131 through the output end to drive the drive wheel 131 to rotate, and output power to the driven wheel 132 through the transmission chain 133.

[0046] The drive module may include, but is not limited to, power output components such as drive motors and drive cylinders. This application does not limit the specific types of components in the drive module.

[0047] Additionally, see Figures 1-2 As shown, this application also provides a continuous moving bed, which includes at least one ion exchange device 100 as described above. Preferably, the continuous moving bed includes multiple ion exchange devices 100, and the ion exchange effect of the material is achieved simultaneously by the multiple ion exchange devices 100 to improve the ion exchange efficiency.

[0048] The aforementioned continuous moving bed, through the sprocket transmission method of the driving wheel 131, driven wheel 132 and transmission chain 133, can improve the stability of the power output from the driving wheel 131 to the driven wheel 132, thereby ensuring the stability of the ion column 110 during rotation, improving the ion exchange effect of the ion exchange device 100, and reducing damage to the ion column 110.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
