Description

Technical Field

[0001] This utility model relates to the technical field of syrup processing, specifically to a mixed-bed ion exchanger with anti-clogging effect. Background Technology

[0002] At certain stages of syrup refining, such as desalting or final purification, a mixed-bed ion exchanger is needed to remove ionic impurities contained in the syrup during processing through its internal resin layer, thereby improving the quality of the final product.

[0003] Mixed-bed ion exchangers are filled with cation exchange resins and anion exchange resins. Backwashing separates the resins into layers and removes impurities. However, in existing mixed-bed ion exchangers, the resin tends to clump together during operation, and impurities are easily adsorbed on the resin surface and inside the mixed bed. These impurities are difficult to remove completely through backwashing, affecting the resin exchange efficiency and the equipment's operating efficiency, and even leading to frequent maintenance.

[0004] Therefore, this application is submitted. Utility Model Content

[0005] The purpose of this invention is to provide a mixed-bed ion exchanger with anti-clogging effect. By installing an anti-clogging component at the top of the tank to prevent impurities from entering the main pipeline through branch pipes during backwashing, and by installing an ultrasonic generator on the surface of the screen tube to periodically treat the resin layer, the invention prevents resin agglomeration and impurity adsorption, thus solving the above-mentioned problems existing in the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0007] A mixed-bed ion exchanger with anti-clogging effect includes a tank, a drain outlet located at the top of the tank and a water inlet located at the bottom of the tank. The tank is provided with a resin layer inside. An anti-clogging component for backflushing discharge is provided above the resin layer and a microwave generator is located below the resin layer. The anti-clogging component includes a main pipe and a branch pipe detachably connected to the bottom of the main pipe. A filter screen is provided at the bottom of the branch pipe.

[0008] Furthermore, the top end of the main pipe is located inside the drain outlet, and its bottom end is provided with multiple threaded holes for threaded connection with branch pipes.

[0009] Furthermore, the inner diameter of the bottom end of the main pipe is larger than the inner diameter of the top end and is bucket-shaped.

[0010] Furthermore, the inner wall of the branch pipe is symmetrically provided with assembly grooves at the bottom, and the outer periphery of the filter screen is fitted with an installation ring with a sliding rod, the sliding rod being detachably connected to the inside of the assembly groove.

[0011] Furthermore, the mounting ring is provided with a sliding groove, and the sliding rod is connected to the sliding groove by a spring.

[0012] Furthermore, the assembly groove, sliding groove, and sliding rod are all T-shaped structures, and the bottom end of the sliding rod is lower than the bottom end of the branch pipe.

[0013] Furthermore, the branch pipe has multiple water outlets on its wall, and the water outlets are located below the assembly groove.

[0014] Furthermore, the outlet is a constant diameter through hole or a variable diameter through hole.

[0015] Furthermore, a sieve tube is disposed below the microwave generator and the microwave generator is located on the surface of the sieve tube.

[0016] Furthermore, a pressure sensor and a flow meter are installed inside the main pipeline.

[0017] The beneficial effects of this utility model are:

[0026] Example 1

[0027] Embodiment 1 of this utility model is a mixed bed ion exchanger with anti-clogging effect, including a tank 1, a drain outlet 11 located at the top of the tank 1 and a water inlet 10 located at the bottom. A resin layer 12 is provided inside the tank 1. An anti-clogging component 2 for backflushing discharge is provided above the resin layer 12 and a microwave generator is located below the resin layer 12. The anti-clogging component 2 includes a main pipe 20 and a branch pipe 21 detachably connected to the bottom end of the main pipe 20. A filter screen 22 is provided at the bottom end of the branch pipe 21.

[0028] Reference Figure 1 This invention mainly achieves this by sequentially setting an anti-clogging component 2 and a microwave generator above and below the resin layer 12, so that impurities can enter the interior of the main pipe 20 during backwashing, preventing impurities from clogging; and by periodically activating the ultrasonic generator, the cavitation, stirring and emulsification effects of ultrasonic waves can be used to break up and disperse the impurities adsorbed inside the mixed bed, preventing resin from clumping and being encapsulated, improving the regeneration effect and exchange capacity of the resin, enhancing the backwashing and regeneration effect, and reducing operating costs and maintenance workload.

[0029] Specifically, the anti-clogging component 2 mainly uses a filter screen 22 installed at the bottom of the branch pipe 21 to block impurities during backwashing, preventing impurities from further entering the interior of the main pipe 20 and causing blockage, thus improving the sewage discharge capacity. At the same time, the branch pipes 21 are evenly arranged at the bottom of the main pipe 20 and can be detachably connected, which facilitates the cleaning of impurities adsorbed by the filter screen 22 in the branch pipes 21. The pore size of the filter screen 22 can be set according to the actual situation to ensure that the requirements for blocking impurities are met. This is a conventional technical operation and will not be described in detail here.

[0030] It should be noted that the microwave generator internally includes an ultrasonic generator 6 and an ultrasonic transducer, which are electrically connected to each other. Under the control of an external controller, it can automatically start according to a preset time cycle. The ultrasonic transducer converts the high-frequency electrical oscillations generated by the ultrasonic generator 6 into high-frequency mechanical vibrations. The propagation of ultrasonic waves in water and resin generates a large number of microbubbles. During the growth, oscillation, and collapse of these bubbles, a huge amount of energy is released, forming strong micro-shock waves and high-speed jets that impact and peel off impurities on the resin surface, separating the impurities from the resin. At the same time, the ultrasonic vibration causes micro-ripples and agitation in the water flow, increasing the relative motion between resin particles, preventing resin particles from agglomerating and sticking, and maintaining the resin's good flowability and dispersibility. In addition, the emulsifying effect of ultrasonic waves can disperse oily or viscous impurities into microparticles, forming an emulsion that is more easily carried away and discharged from the mixed bed by the water flow. Before backwashing or regeneration operations, the ultrasonic device can be started in advance to loosen the impurities inside the resin, so that they can be more effectively discharged from the mixed bed in subsequent operations, improving the efficiency of backwashing and regeneration, and reducing the time and water consumption of backwashing and regeneration. The specific assembly and working principle of the ultrasonic generator 6 here are conventional technical operations of existing technology, and will not be described in detail here.

[0031] In some preferred embodiments, the top end of the main pipe 20 is located inside the drain outlet 11, and its bottom end is provided with a plurality of threaded holes 200 for threaded connection with the branch pipes 21. The inner diameter of the bottom end of the main pipe 20 is larger than the inner diameter of the top end and is funnel-shaped. (Refer to...) Figure 2 By setting a threaded hole 200 at the bottom of the main pipe 20 to connect with the top of the branch pipe 21, it is convenient to carry out maintenance and cleaning between the main pipe 20 and the branch pipe 21. Furthermore, the bottom inner diameter of the main pipe 20 is large and it is funnel-shaped, which is conducive to increasing the number of branch pipes 21 at its bottom and increasing the water output capacity.

[0032] Furthermore, it can be noted that the inner wall of the branch pipe 21 is symmetrically provided with assembly grooves 211 at its bottom, and the outer periphery of the filter screen 22 is fitted with an installation ring 23 having a sliding rod 232, the sliding rod 232 being detachably connected to the inside of the assembly groove 211. The installation ring 23 has a sliding groove 230 inside, and the sliding rod 232 is connected to the sliding groove 230 by a spring 231.

[0033] To allow for the separate cleaning of impurities adsorbed by the filter screen 22 without disassembling the branch pipe 21, a detachable connection is provided at the bottom of the branch pipe 21 for the filter screen 22. Specifically, a sliding rod 232 extends and retracts within a sliding groove 230. When the sliding rod 232 moves vertically upward into the mounting groove 211 on the wall of the branch pipe 21, it is pushed into the mounting groove 211 by the elastic force of the spring 231, thus achieving the detachable assembly of the filter screen 22 within the branch pipe 21. For disassembly, simply push the sliding rod 232 to compress the spring 231, moving it into the sliding groove 230 until it is fully positioned within it, allowing the filter screen 22 to be removed from the outside of the branch pipe 21. The inner diameter of the mounting ring 23 is the same as the inner wall of the branch pipe 21.

[0034] Furthermore, referring to Figure 3 The assembly groove 211, sliding groove 230, and sliding rod 232 are all T-shaped, and the bottom end of the sliding rod 232 is lower than the bottom end of the branch pipe 21. A cross-sectional view of the assembly groove 211 is shown here. The specific shapes of the assembly groove 211, sliding groove 230, and sliding rod 232 are defined. The top width of the sliding rod 232 is greater than the bottom width. The top is mainly used for the assembly of the sliding rod 232 in the assembly groove 211 and for its extension and retraction within the sliding groove 230. The bottom length of the sliding rod 232 is greater than the bottom length of both the sliding groove 230 and the assembly groove 211, allowing the bottom of the sliding rod 232 to move within the sliding groove 230 and the bottom of the assembly groove 211, thus assembling the sliding rod 232. The bottom width of the sliding groove is less than or equal to the bottom width of the assembly groove 211 to meet the assembly of the bottom of the sliding rod 232. The top width of the sliding groove 230 and the top width of the assembly groove 211 are the same as the top outer width of the sliding rod 232 to ensure that they are assembled in a compatible manner and reduce the entry of impurities into the interior of the branch pipe 21 from the gaps between them.

[0035] Example 2

[0036] This embodiment 2 is implemented based on embodiment 1. The branch pipe 21 has multiple outlets 210 on its wall, located below the assembly groove 211. The outlets 210 are either equal-diameter or variable-diameter through holes. The outlets 210 facilitate increasing the water outlet area entering the branch pipe 21 and main pipe 20 during backwashing. Multiple rows of outlets 210 can be arranged vertically; their specific specifications and shapes can be determined according to actual conditions and are not listed here. Simultaneously, the outlets 210 are mainly located below the assembly groove 211, i.e., below the filter screen 22, further improving the impurity blocking effect. Furthermore, the bottom surface of the sliding rod 232 is lower than the bottom surface of the branch pipe 21, facilitating the disassembly of the filter screen 22.

[0037] Example 3

[0038] This embodiment 3 is implemented based on embodiment 1. A sieve tube 13 is arranged below the microwave generator, and the microwave generator is located on the surface of the sieve tube 13. The ultrasonic transducer converts the high-frequency electrical oscillations generated by the ultrasonic generator 6 into high-frequency mechanical vibrations, which are transmitted to the resin and water flow near the bottom sieve tube 13. The propagation of ultrasonic waves in the water and resin generates a large number of microbubbles. During the growth, oscillation, and collapse of these bubbles, a huge amount of energy is released, forming strong micro-shock waves and high-speed jets. These jets impact and peel off impurities on the resin surface, causing the impurities to separate from the resin. This is existing technology and will not be described in detail here.

[0039] In some preferred embodiments, a pressure sensor 4 and a flow meter 5 are installed inside the main pipeline 20. With the connection to an external controller, the pressure sensor 4 is used to monitor pressure changes within the main pipeline 20 in real time, and the flow meter 5 is used to monitor the backwash discharge flow rate, ensuring the backwash effect and the stability and reliability of the mixed-bed ion exchanger.

[0040] The working principle of this utility model is as follows: The anti-clogging component 2 installed inside the tank 1 blocks impurities during backwashing through the filter screen 22 at the bottom of the branch pipe 21, preventing impurities from further entering the interior of the main pipe 20 and causing blockage, thereby improving the sewage discharge capacity; at the same time, the branch pipes 21 are evenly arranged at the bottom of the main pipe 20 and can be detachably connected, which facilitates the cleaning of impurities adsorbed by the filter screen 22 in the branch pipes 21, thereby improving the sewage discharge effect; at the same time, the ultrasonic generator 6 located on the surface of the screen tube 13 can use the cavitation, stirring and emulsification effects of ultrasonic waves to break up and disperse the impurities adsorbed inside the mixed bed, avoid resin agglomeration and encapsulation, improve the regeneration effect and exchange capacity of the resin, enhance the backwashing and regeneration effect, and reduce operating costs and maintenance workload.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent substitutions, and improvements made to the above embodiments based on the technical essence of the present utility model and within the spirit and principles of the present utility model shall still fall within the protection scope of the present utility model.
