Description

Technical Field

[0001] This invention relates to a high-density cation exchange device, belonging to the field of cation exchange technology. Background Technology

[0002] High-density cation exchangers are widely used in industrial water treatment, nuclear waste purification, and pharmaceuticals, especially in high-purity water preparation and heavy metal ion recovery, where efficient and stable cation-selective exchange is required. The core requirement is to maximize exchange capacity and kinetic efficiency through high-density packed ion exchange resin to meet stringent process standards such as semiconductor-grade water quality or radioactive waste treatment.

[0003] Traditional cation exchangers employ a single-channel funnel design, lacking internal flow guidance structures. This leads to channeling or short-circuiting phenomena when the solution flows in, resulting in uneven packing distribution and localized loosening of the packing material. Furthermore, the absence of an external dynamic compaction mechanism exacerbates resin sedimentation and reduces packing density over long-term operation. This not only reduces exchange efficiency by 15-20% but also causes flow rate imbalances, sudden increases in pressure drop, and the risk of blockage, severely impacting system stability and processing accuracy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-density cation exchange device to solve the problems of the existing technology.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A high-density cation exchange device includes: a column, a receiving funnel at the upper end of the column, an overflow receiving funnel in the middle of the receiving funnel, and a plurality of flow guiding ribs between the receiving funnel and the overflow receiving funnel. The flow guiding ribs separate the internal space of the receiving funnel to form multiple flow channels, and the flow channels are filled with a filling material.

[0007] A resonant component is fitted outside the receiving funnel, and the filling density is achieved through the resonant component.

[0008] As a further improvement, the resonant assembly includes a rubber sleeve fitted on the outer surface of the receiving funnel, a protective sleeve fitted outside the rubber sleeve, and multiple sets of vibrators disposed between the rubber sleeve and the protective sleeve. The vibrators are embedded and fixed inside the protective sleeve, and the multiple sets of vibrators are connected in series and electrically connected to the control module via a power line below. The control module controls the start and stop of the vibrators.

[0009] As a further improvement, the vibrator employs a piezoelectric ceramic stack actuator / ultrasonic transducer.

[0010] As a further improvement, it also includes a control module and a display panel mounted on the base. The control module is electrically connected to the display panel and the resonant component. When the filling material is loaded into the receiving funnel, the control module controls the resonant component to compact the filling density of the filling material through high-frequency vibration.

[0011] As a further improvement, the support frame includes a base placed flat on the workbench, a support rod vertically mounted on the base, and the side of the support rod is fixedly connected to the connecting strip by at least two sets of auxiliary rods, the auxiliary rods forming a triangular structure.

[0012] As a further improvement, the two ends of the auxiliary rod are fixedly connected to the support rod and the adjacent strip by welding.

[0013] As a further improvement, an open slot is provided on the side of the base away from the support frame, the receiving cup is inserted into the open slot, and the receiving cup is placed directly below the column.

[0014] As a further improvement, the guide ribs spiral around the overflow receiving hopper from top to bottom to form a spiral structure, and the flow channel is formed by two adjacent guide ribs to form a spiral flow channel.

[0015] As a further improvement, the guide ribs are provided in 12 sets, wherein the spiral guide channel has an inclination of 15°-25° at one-third of the height of the receiving funnel, and the spiral guide channel has an inclination of 45°-60° at one-third of the height of the receiving funnel.

[0016] As a further improvement, the inclination degree of the spiral guide channel gradually increases from top to bottom.

[0017] Beneficial effects:

[0018] This invention precisely solves the core defects of traditional devices through the synergistic cooperation of the flow-guiding ribs and the resonant components. The flow-guiding ribs construct a multi-channel structure in the receiving funnel, forcing the solution to flow evenly, completely eliminating channeling and short-circuiting phenomena, and ensuring that the ion exchange resin filling material is distributed at a high degree.

[0019] Meanwhile, the external resonant components apply controllable high-frequency vibrations to dynamically compact the resin bed, compensate for the sedimentation effect during operation in real time, maintain a high-density filling state, and avoid the decay of exchange capacity.

[0020] During use, after the solution is introduced through the receiving funnel, it is guided by the flow guide fins to form multiple stable flows that flow evenly through each filled channel to achieve efficient ion exchange.

[0021] The resonant assembly is activated during the pre-operation loading process by vibrating to compact the filler. It can also be activated synchronously in subsequent operations. The filling density is optimized by adjusting vibration parameters, ensuring continuous and stable processing. This significantly improves exchange kinetic efficiency and resin utilization, reduces pressure drop fluctuations and clogging risks, and extends equipment lifespan, making it particularly suitable for high-precision applications such as semiconductor-grade water treatment.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Reference Figure 1-6 As shown, a high-density cation exchange device includes: a column 1, a receiving funnel 2 at the upper end of the column 1, an overflow receiving hopper 21 in the middle of the receiving funnel 2, and a plurality of flow guiding ribs 22 between the receiving funnel 2 and the overflow receiving hopper 21. The flow guiding ribs 22 separate the internal space of the receiving funnel 2 to form multiple flow channels, and the flow channels are filled with a filling material 23.

[0033] A resonant component 5 is fitted outside the receiving funnel 2, and the density of the filling material 23 is achieved through the resonant component 5.

[0034] Through the coordinated cooperation of the flow guiding fins 22 and the resonant component 5, the core defects of traditional devices are precisely solved. The flow guiding fins 22 construct a multi-channel structure in the receiving funnel 2, which forces the solution to flow evenly, completely eliminates channeling and short-circuiting phenomena, and ensures that the ion exchange resin of the filler 23 is distributed with a high degree of uniformity.

[0035] Meanwhile, the external resonant component 5 applies controllable high-frequency vibration to dynamically compact the resin bed, compensate for the sedimentation effect during operation in real time, maintain a high-density filling state, and avoid the decay of exchange capacity.

[0036] During use, after the solution is introduced through the receiving funnel 2, it is guided by the flow guide fins 22 to form multiple stable flows that flow evenly through each filled channel to achieve efficient ion exchange.

[0037] The resonant component 5 is activated during the pre-operation loading process, compacting the filler 23 through vibration. It can also be activated synchronously in subsequent operations. By adjusting the vibration parameters, the filling density is optimized to ensure continuous and stable processing. This significantly improves exchange kinetic efficiency and resin utilization, reduces pressure drop fluctuations and the risk of blockage, and extends equipment life. It is particularly suitable for high-precision applications such as semiconductor-grade water treatment.

[0038] Compared to existing single-channel devices, this solution increases the exchange capacity by more than 20%, enhances pressure drop stability by 30%, and eliminates the settling problem of traditional static filling through the resonant compaction mechanism. It eliminates the need for frequent shutdowns for maintenance, significantly improves system reliability and processing accuracy, and meets stringent industrial standards.

[0039] The resonant assembly 5 includes a rubber sleeve 54 fitted on the outer surface of the receiving funnel 2, a protective sleeve 51 fitted on the outside of the rubber sleeve 54, and multiple sets of vibrators 52 disposed between the rubber sleeve 54 and the protective sleeve 51. The vibrators 52 are embedded and fixed inside the protective sleeve 51. The multiple sets of vibrators 52 are connected in series and electrically connected to the control module 4 through the lower power line 53. The control module 4 controls the start and stop of the vibrators 52.

[0040] As a further improvement, the vibrator 52 employs a piezoelectric ceramic stack actuator / ultrasonic transducer. Since the piezoelectric ceramic stack actuator / ultrasonic transducer is a readily available product, it will not be described in detail.

[0041] By adopting a double-layer encapsulation structure of rubber sleeve 54 and protective sleeve 51 for the resonant component 5, the rubber sleeve 54 tightly fits the outer wall of the funnel 2 to provide elastic buffer, while the protective sleeve 51 forms a rigid protective layer, and multiple sets of micro vibrators 52 are embedded between the two.

[0042] This structure effectively isolates external mechanical impacts, prevents vibration energy loss, ensures precise vibration transmission to the filling channels, and prevents resin particles from penetrating into the vibrating unit and causing wear. Several vibrators 52 are connected to the control module 4 via a series circuit. During operation, the control module 4 adjusts the vibration frequency and amplitude in real time. For different working conditions, such as high flow rates or high viscosity solutions, it dynamically activates and forcibly compacts the resin bed, completely eliminating density gradients and channeling phenomena caused by resin sedimentation, and maintaining the uniformity of flow rate and pressure drop stability during the exchange process.

[0043] In this embodiment, a piezoelectric ceramic stack actuator is selected, which is composed of multiple layers of lead zirconate titanate (PZT) and piezoelectric ceramic sheets precisely stacked. When a voltage is applied, each layer generates a micron-level coordinated displacement, and the cumulative output is a high-precision linear vibration.

[0044] Alternatively, ultrasonic transducers can be used, which convert electrical energy into high-frequency mechanical oscillations, typically 20-100kHz, based on the piezoelectric effect. Both are manufactured using thin-film and microelectromechanical systems (MEMS) processes, and their individual unit sizes can be compressed to the millimeter level, such as 5×5×2mm. Thanks to the high energy density characteristics of piezoelectric materials and the spatial optimization of the stacked structure, they can be efficiently integrated within narrow annular gaps.

[0045] Its miniaturized design originates from semiconductor-grade precision machining technology. Through co-sintering process, it achieves a dense bond between multilayer electrodes and ceramic dielectric, eliminating the need for additional heat dissipation space and perfectly fitting the compact layout of the funnel's outer wall.

[0046] In practical applications, this vibration unit generates high-frequency micro-amplitude vibrations with low power consumption, accurately compensating for resin bed sedimentation, controlling the filling density fluctuation within ±2%, significantly improving the stability of exchange capacity, reducing the decay rate to below 5%, and extending the equipment's maintenance-free cycle by up to 30%. It is suitable for scenarios with stringent requirements for density consistency, such as the preparation of semiconductor-grade ultrapure water.

[0047] It also includes a control module 4 and a display panel 41 mounted on the base 34. The control module 4 is electrically connected to the display panel 41 and the resonant component 5. When the filling material 23 is loaded into the receiving funnel 2, the control module 4 controls the resonant component 5 to compact the filling density of the filling material 23 through high-frequency vibration.

[0048] Since the control module 4 is integrated into the equipment base 34 and electrically connected to the display panel 41 and the resonant component 5, precise control of the filling process can be achieved.

[0049] During operation, in the stage of loading ion exchange resin, the control module 4 automatically triggers the resonant component 5 to apply high-frequency vibration of 50-100kHz. This frequency range is based on the micro-amplitude mechanical oscillation generated by the piezoelectric effect, which is <10μm. This can efficiently induce the resin particles to rearrange themselves in a coordinated manner, eliminate filling gaps, and ensure density uniformity.

[0050] This high-frequency band avoids particle breakage or energy loss caused by low-frequency vibration, increasing the initial filling density by more than 15%, and completely solving the channeling and settling problems caused by density gradients in traditional static filling.

[0051] In practical applications, operators can monitor and adjust vibration parameters in real time through the display panel 41 to maintain resin bed density fluctuations ≤ ±2%, significantly extending the maintenance-free cycle of the equipment and ensuring exchange efficiency and long-term stability in scenarios such as high-purity water treatment.

[0052] The support frame 3 includes a base 34 placed flat on the workbench and a support rod 35 vertically installed on the base 34. The side of the support rod 35 is fixedly connected to the connecting strip by at least two sets of auxiliary rods 36, and the auxiliary rods 36 form a triangular structure.

[0053] The two ends of the auxiliary rod 36 are fixedly connected to the support rod 35 and the adjacent strip 31 by welding.

[0054] The support frame 3 adopts a layout with the base 34 placed on the workbench and the support rod 35 installed vertically. The side of the support rod 35 is welded to the connecting strip through at least two sets of auxiliary rods 36 to form a triangular structure.

[0055] This structure provides rigid support during equipment operation, especially when the resonant component 5 activates high-frequency vibrations of 50-100kHz.

[0056] The triangular configuration significantly enhances bending strength and torsional stiffness, effectively suppressing displacement or tilting of column 1 caused by vibration; the welded connection ensures that there is no risk of loosening between auxiliary rod 36, support rod 35, and connecting strip, avoiding mechanical fatigue caused by long-term vibration.

[0057] In practical applications, during installation, the base 34 is fixed to the workbench, and after the support rod 35 is vertically positioned, the auxiliary rod 36 is welded to form a stable triangular frame, ensuring that the entire device maintains absolute verticality and stability during resin filling and exchange. This design completely solves the swaying and resonance problems that easily occur in traditional support structures under high-frequency vibration, prevents channel deformation or sealing failure caused by micro-displacement of the column 1, ensures that the flow rate uniformity fluctuation during the exchange process is controlled within ±3%, extends the service life of the equipment, and guarantees operational accuracy under harsh conditions such as high-purity water treatment.

[0058] An open slot 37 is provided on the side of the base 34 away from the support frame 3. The receiving cup 38 is inserted into the open slot 37 and placed directly below the column 1. The open slot 37 can accurately control the movement trajectory of the receiving cup 38, allowing it to move precisely to the bottom of the column 1. During use, the open slot 37 can also be used to keep the receiving cup 38 in a stable state, preventing it from shifting to either side.

[0059] The flow guide ribs 22 spiral around the overflow receiving hopper 21 from top to bottom to form a spiral structure, and the flow channel is formed by two adjacent flow guide ribs 22 to form a spiral flow guide channel.

[0060] As a further improvement, the guide ribs 22 are provided in 12 sets, wherein the spiral guide channel has an inclination of 15°-25° at one-third of the height of the receiving funnel 2, and the spiral guide channel has an inclination of 45°-60° at one-third of the height of the receiving funnel 2.

[0061] As a further improvement, the inclination degree of the spiral guide channel gradually increases from top to bottom.

[0062] The guide ribs 22 are arranged in a layout of 12 sets of spirals around the overflow receiving hopper 21 to form a continuous spiral guide channel. After the solution flows into the receiving funnel 2, it spirals down the channel.

[0063] During operation, the upper third of the height is tilted at an angle of 15°-25° to ensure smooth fluid dispersion and avoid channeling and short circuits caused by inlet turbulence;

[0064] The lower section gradually increases in inclination to 45°-60° to accelerate flow, forcing resin particles to rearrange themselves and eliminating density gradients caused by sedimentation. This inclination gradient design is based on fluid dynamics principles.

[0065] The upper low angle maintains the laminar flow state, which improves the uniformity of the flow velocity distribution to a coefficient of variation of <5%, effectively preventing local loosening in the initial filling stage;

[0066] The lower, high-angle design utilizes gravitational potential energy to enhance the compaction effect, controlling resin bed density fluctuations within ±1.5% and eliminating void formation during operation. The number of 12 fins has been optimized and verified through computational fluid dynamics. Within a critical range of 10-15 fins, it maximizes the number of flow channels to ensure an exchange efficiency increase of over 25%, while avoiding a sudden increase in pressure drop caused by excessive fins, maintaining a pressure of <0.5 bar. This completely solves the capacity decay and clogging risks caused by flow velocity imbalance in traditional single-channel devices, ensuring long-term stability and processing accuracy in high-precision scenarios such as semiconductor-grade water treatment.
