Description

Technical Field

[0001] The present invention relates to the technical field of filtration and separation, and in particular to an ammonium perchlorate crystal anti-liquidation treatment device and a treatment method thereof. Background Art

[0002] Anti-clustering agents are important additives used to prevent ammonium perchlorate crystals from clumping during storage and transportation. They work by forming a protective film on the crystal surface or altering its surface properties. The anti-clustering treatment unit is designed to purify used anti-clustering agents for secondary use, thereby reducing costs, minimizing resource waste, and improving production sustainability.

[0003] However, traditional anti-condensation treatment equipment has many significant shortcomings. In terms of structural design, they are often simple combinations of single-function equipment, lacking systematicity and integration. For example, filtration, ion exchange, and distillation processes are often independent, not only occupying a large area but also requiring a cumbersome process, requiring extensive manual operation and transportation, significantly reducing treatment efficiency and increasing costs.

[0004] To this end, the present invention proposes an ammonium perchlorate crystal anti-condensation treatment device and method. Through an innovative modular design, this device integrates liquid delivery, filtration, ion exchange, distillation, and adsorption functions, achieving efficient, one-stop, full-process treatment. Utilizing a unique liquid delivery structure, easily replaceable filter elements, ion exchange and adsorption filter chambers with inclined baffles, and a precisely controlled distillation system, this device achieves comprehensive and in-depth purification and anti-condensation treatment. It also significantly improves equipment maintenance convenience, reduces maintenance costs, and ensures long-term stable operation. Summary of the Invention

[0020] In one possible implementation, a method for preventing ammonium perchlorate crystals from condensing is implemented in the above-mentioned treatment device, the method comprising:

[0021] Step 1: The waste liquid is introduced into the liquid delivery tank through the water pump b and the water inlet pipe;

[0022] Step 2: Liquid feeding operation: The motor drives the threaded rod to rotate, which in turn drives the liquid feeding plate to move downward in the liquid feeding box. The liquid feeding plate squeezes the liquid in the box and discharges it into the upper side of the liquid feeding plate through the infusion hole. The motor reverses, driving the liquid feeding plate to move upward. The hydraulic pressure moves the sealing plate downward to block the infusion hole. The liquid flows into the filter box under the pressure of the liquid feeding plate.

[0023] Step 3: Primary filtration: The liquid is filtered through the filter element as it flows into the filter box. The primary filtration can intercept larger ammonium perchlorate particles, dust, and other mechanical impurities in the ammonium perchlorate crystal-preventing liquid. The filtered liquid is discharged into the exchange box through the drainage hole at the top edge of the filter box.

[0024] Step 4: Ion exchange: ion exchange resin is added between the two partitions a in the exchange box through the feed port a in advance to form an ion exchange layer; the liquid flowing into the upper side of the exchange box from the drainage hole penetrates the ion exchange layer into the lower side under the action of gravity; the ion exchange resin absorbs the iron ions, copper ions, and zinc ions in the anti-caking liquid through the ion exchange reaction, thereby reducing the metal ion content;

[0025] Step 5: The liquid is transported to the distillation box. The solenoid valve in the middle of the delivery pipe a is opened to transport the treated liquid at the bottom of the exchange box to the inside of the distillation box through the delivery pipe a.

[0026] Step 6: Distillation operation: Turn on the electric heating plate to heat the liquid in the box, and use the difference in boiling points of different substances to separate the water in the anti-condensation liquid and some impurities with different boiling points from ammonium perchlorate and the active ingredient;

[0027] Step 7: The liquid is transported to the adsorption box. The distilled liquid is transported to the top of the adsorption box through the delivery pipe b.

[0028] In step 8, an adsorption operation is performed. An activated carbon adsorbent is added between the two partitions b to form an activated carbon adsorption layer. The liquid penetrates the activated carbon adsorption layer under the action of gravity, enters the lower side of the partition b after adsorption, and is finally discharged and collected through the drain port. The activated carbon adsorbent adsorbs the organic impurities and other trace impurities in the decomposition products of the surfactant in the anti-caking liquid, thereby further purifying the anti-caking liquid.

[0029] In a possible implementation, the device in the device box is inspected through the inspection port, and the filter element is replaced by rotating the top cover and the handle on the top of the filter element to separate the block from the slot.

[0030] Beneficial effects compared with existing technologies:

[0031] 1. This solution utilizes a unique modular design, integrating liquid delivery, filtration, ion exchange, distillation, and adsorption into a single, integrated device. This achieves efficient, one-stop, full-process treatment for ammonium perchlorate crystal condensation. The liquid delivery tank, equipped with a motor, threaded rods, and a specially constructed liquid delivery plate, precisely controls the incoming wastewater and distributes it to the filtration stage in an orderly fashion. The easily replaceable filter cartridges within the filter box effectively intercept large impurities. The exchange box utilizes ion exchange resins placed between inclined partitions to efficiently remove metal ions under gravity-assisted pressure, making resin replacement easy. The distillation box utilizes heating plates, condensing plates, temperature and pressure sensors, and a vacuum pump to precisely control the distillation process, separating impurities and concentrating the active ingredients. The adsorption box further purifies the liquid with its tilted activated carbon adsorption layer. The coordinated operation of these modules significantly improves treatment efficiency, reduces manual intervention, lowers processing costs, and ensures stable and reliable treatment results.

[0032] 2. This solution achieves comprehensive and in-depth purification of the various complex impurities in ammonium perchlorate crystal anti-caking liquid through a cleverly designed multi-step treatment process. Mechanical filtration first removes large ammonium perchlorate crystals, dust, and mechanical impurities, laying the foundation for subsequent fine processing. Next, an ion exchange step utilizes specific ion exchange resins for precise adsorption and removal of metal ions, preventing their negative impact on anti-caking performance. The distillation step utilizes differences in boiling points to separate water and low-boiling impurities from the active ingredients, not only removing impurities but also concentrating the active ingredients and improving the quality of the anti-caking liquid. Finally, the adsorption step leverages the powerful adsorption properties of activated carbon to absorb organic impurities such as surfactant decomposition products and residual trace impurities, achieving extremely high purity of the anti-caking liquid. This seamless process provides targeted treatment of various impurities, comprehensively improving the quality of the anti-caking liquid and meeting the most demanding application scenarios.

[0033] 3. In this solution, by setting up a structure that is convenient for maintenance and replacement of components, long-term stable operation and low-cost maintenance of the equipment are achieved. The filter box is designed with a card block and a card slot, so that when the filter element needs to be replaced, it can be easily completed by turning the top cover and operating the handle on the top of the filter element. There is no need for a complicated disassembly process, which saves maintenance time and manpower. The inclined partition design of the exchange box allows the used ion exchange resin to be automatically discharged from the discharge port under the action of gravity, which is convenient for rapid replacement of resin and ensures the continuous and stable ion exchange effect. Similarly, the adsorption box has an inclined filter bin for easy replacement of activated carbon adsorbent. In addition, the inspection port opened in the middle of the main body facilitates management personnel to perform daily inspection and maintenance of the core equipment in the equipment box. These designs reduce the risk of equipment failure, extend the service life of the equipment, reduce downtime caused by equipment maintenance, improve overall production efficiency, and reduce long-term operating costs.

DETAILED DESCRIPTION

[0043] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can be implemented in various forms, and therefore the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, components that are not related to the present invention will be omitted from the drawings.

[0044] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0045] Example 1: Please refer to Figures 1 to 7 As shown, this embodiment introduces the specific structure of an ammonium perchlorate crystal anti-liquidation treatment device, including a main body 1, wherein a liquid feeding box 2, a filter box 10, an exchange box 15, an equipment box 19, a distillation box 21, and an adsorption box 25 are provided inside the main body 1. The filter box 10 and the liquid feeding box 2 are connected vertically and arranged on the upper side of the main body 1. The exchange box 15 is also arranged on the upper side of the main body 1 and is arranged in an annular shape and wrapped around the outside of the liquid feeding box 2 and the filter box 10. The equipment box 19 is arranged in the middle of the main body 1, the distillation box 21 is arranged on the lower side of the main body 1, and the adsorption box 25 is also arranged on the lower side of the main body 1 and is arranged in an annular shape and wrapped around the outside of the distillation box 21.

[0046] A motor 4 is installed at the top of the main body 1, and a threaded rod 3 is fixedly connected to the output end of the motor 4. The threaded rod 3 passes through the filter box 10 and is placed inside the liquid feeding box 2. Two sliding rods a5 are installed inside the liquid feeding box 2. A liquid feeding plate 6 is slidably connected between the two sliding rods a5. The liquid feeding plate 6 is threadedly connected to the middle of the liquid feeding plate 6. A plurality of infusion holes 7 are opened in the middle of the liquid feeding plate 6. The middle parts of the plurality of infusion holes 7 are fixedly connected to a plurality of sliding rods b8. The outer parts of adjacent plurality of sliding rods b8 are slidably connected to a sealing plate 9.

[0047] A water inlet pipe 31 is installed inside the equipment box 19, and a water pump b32 is installed in the middle of the water inlet pipe 31. The output end of the water inlet pipe 31 is connected to the bottom of the liquid delivery box 2, and the input end of the water inlet pipe 31 is connected to the waste liquid tank;

[0048] Specifically, the waste liquid can be discharged into the liquid feeding box 2 through the water inlet pipe 31 by the water pump b32. At this time, the liquid feeding plate 6 is located on the upper side of the liquid feeding box 2. When the liquid volume inside the liquid feeding box 2 reaches a certain amount, the motor 4 is started, and the motor 4 drives the threaded rod 3 to rotate. Since the threaded rod 3 is threadedly connected to the liquid feeding plate 6, and the liquid feeding plate 6 slides outside the two sliding rods a5 and is restricted in rotation, the threaded rod 3 can drive the liquid feeding plate 6 to move up and down inside the liquid feeding box 2.

[0049] When the liquid feeding plate 6 moves downward inside the liquid feeding box 2, the liquid feeding plate 6 squeezes the liquid inside the liquid feeding box 2, causing the liquid to be discharged into the upper side of the liquid feeding plate 6 through the infusion hole 7. At this time, the sealing plate 9 is pushed upward by the liquid under the action of the hydraulic pressure, thereby opening the channel between the upper and lower parts of the liquid feeding plate 6, namely the infusion hole 7;

[0050] When the liquid feeding plate 6 is completely moved to the lower side of the liquid feeding box 2, the liquid inside the liquid feeding box 2 is also transported to the upper side of the liquid feeding plate 6. At this time, the motor 4 drives the threaded rod 3 to reverse, and then drives the liquid feeding plate 6 to move upward. When the liquid feeding plate 6 is driven to move upward, due to the effect of hydraulic pressure, the sealing plate 9 is squeezed, and then the infusion hole 7 is blocked. Therefore, the liquid will flow into the interior of the filter box 10 under the pressure of the liquid feeding plate 6.

[0051] The filter box 10 is provided with a plurality of filter elements 11, the top of each filter element 11 being fixedly connected with a clamping block 12. The filter box 10 is provided with a clamping slot 13 at a position flush with the top of each filter element 11. The clamping block 12 engages with the clamping slot 13 to fix the filter element 11 in the filter box 10.

[0052] Specifically, when the liquid is transported to the interior of the filter box 10 through the liquid feeding plate 6, the liquid will pass through the filter element 11, and then the liquid will be initially filtered by the filter element 11. The initial filtration serves to intercept larger ammonium perchlorate particles, dust and other mechanical impurities in the ammonium perchlorate crystals to prevent the liquid from condensing;

[0053] A top cover 33 is provided at the top of the main body 1, and a plurality of drainage holes 14 are provided at the top edge of the filter box 10;

[0054] Specifically, the top cover 33 is used to replace the filter element 11. By rotating the handle on the top of the filter element 11, the filter element 11 is rotated, and the block 12 is separated from the slot 13 by the rotation. Then, the engagement between the block 12 and the slot 13 is released, and the filter element 11 is taken out and replaced.

[0055] Specifically, when the liquid is filtered through the filter element 11 and enters the top of the filter box 10, the liquid will be discharged into the interior of the exchange box 15 through the drainage hole 14;

[0056] The middle part of the exchange box 15 is fixedly connected to two upper and lower partitions a16, and the middle part of the two partitions a16 is provided with a penetration hole. The two partitions a16 are arranged in parallel, with one high and one low on both sides. An inclined filter bin is formed between the two partitions a16. A feed port a17 is provided on the right side of the top of the main body 1, and a discharge port a18 is provided in the middle of the left side of the main body 1. The feed port a17 is connected to the top of the filter bin formed by the two partitions a16, and the discharge port a18 is connected to the bottom of the filter bin formed by the two partitions a16.

[0057] Specifically, ion exchange resin can be added between the two partitions a16 through the feed port a17. By filling the space between the two partitions a16 with ion exchange resin, an ion exchange layer can be formed in the middle of the exchange box 15. The liquid after the initial filtration flows into the upper side of the exchange box 15 from the drainage hole 14 and penetrates from the ion exchange layer into the lower side of the exchange box 15 under the action of gravity. The ion exchange reaction carried out by the ion exchange resin can adsorb metal ions in the anti-caking liquid, such as iron ions, copper ions, and zinc ions, on the resin, thereby effectively reducing the content of metal ions in the anti-caking liquid and preventing the metal ions from having an adverse effect on the anti-caking performance.

[0058] Since the two partitions a16 are arranged at an angle, the used ion exchange resin can be discharged through the discharge port a18 under the action of gravity, which facilitates the replacement of the ion exchange resin.

[0059] A delivery pipe a20 is installed inside the equipment box 19. The input end of the delivery pipe a20 is connected to the bottom of the exchange box 15. The output end of the delivery pipe a20 passes through the middle of the lower side of the main body 1 and is connected to the interior of the distillation box 21. A solenoid valve 35 is installed in the middle of the delivery pipe a20.

[0060] Specifically, the exchange box 15 and the distillation box 21 are connected by a delivery pipe a20, and the liquid inside the exchange box 15 is delivered to the inside of the distillation box 21 through the solenoid valve 35. The solenoid valve 35 also prevents the liquids inside the exchange box 15 and the distillation box 21 from interfering with each other.

[0061] An electric heating plate 22 is installed at the bottom end of the interior of the distillation box 21, and a plurality of condensation plates 23 are installed on the upper side of the interior of the distillation box 21. The plurality of condensation plates 23 are designed to be staggered and tilted up and down, and a groove is formed between the lowest condensation plate 23 and the inner wall of the distillation box 21. The bottom end of the lowest condensation plate 23 is connected to a drain pipe 24, which runs through the distillation box 21. The output end of the drain pipe 24 is arranged on the outside of the main body 1. The purpose is to collect the liquid condensed by the condensation plate 23 through the groove between the condensation plate 23 and the distillation box 21, and then discharge it through the drain pipe 24. A sealing valve 39 is installed at the output end of the drain pipe 24.

[0062] A temperature sensor 36 and a pressure sensor 37 are installed inside the distillation box 21. A vacuum pump 38 is installed inside the equipment box 19. The vacuum pump 38 is connected to the distillation box 21. The temperature sensor 36 is used to detect the internal temperature of the distillation box 21. The pressure sensor 37 is used to monitor the internal pressure of the distillation box 21. The vacuum pump 38 is used to maintain a vacuum state inside the distillation box 21.

[0063] Specifically, after the liquid enters the distillation box 21, it is heated by the electric heating plate 22, and the heating process is controlled in real time by the temperature sensor 36. By utilizing the differences in boiling points of different substances during the distillation process, the water in the anti-caking liquid and impurities with boiling points that differ significantly from ammonium perchlorate and the effective ingredients in the anti-caking liquid, such as some surfactant decomposition products, are separated. By controlling the distillation temperature and vacuum degree, the impurities are first vaporized and evaporated, achieving separation from the ammonium perchlorate and other useful ingredients. For ammonium perchlorate crystal anti-caking liquid, the distillation module can also concentrate the effective ingredients, remove excess water or low-boiling-point impurities, and increase the concentration of the effective ingredients in the anti-caking liquid, thereby improving its performance and use effect.

[0064] During the heating distillation process, the sealing valve 39 and the solenoid valve 35 are in a closed state, so as to keep the interior of the distillation box 21 in a sealed state;

[0065] A delivery pipe b26 is installed on the outside of the main body 1. The delivery pipe b26 passes through the bottom of the distillation box 21 and the top of the adsorption box 25. The output end of the delivery pipe b26 is connected to the top of the adsorption box 25, and the input end of the delivery pipe b26 is connected to the bottom of the distillation box 21. A water pump a27 is installed in the middle of the delivery pipe b26.

[0066] The middle part of the adsorption box 25 is fixedly connected to two upper and lower partitions b28, and the middle parts of the two partitions b28 are provided with permeation holes. The two partitions b28 are arranged in parallel, with one high and one low on both sides. An inclined filter bin is formed between the two partitions b28, and a feed port b29 is provided in the middle part of the right side of the main body 1. A discharge port b30 is provided at the bottom left side of the main body 1. The feed port b29 is connected to the top of the filter bin formed by the two partitions b28, and the discharge port b30 is connected to the bottom end of the filter bin formed by the two partitions b28. A drain port 40 is fixedly connected to the bottom of the rear side of the main body 1, and the drain port 40 is connected to the bottom of the adsorption box 25;

[0067] Activated carbon adsorbent can be added between the two partitions b28 through the feed port b29. By filling the space between the two partitions b28 with activated carbon adsorbent, an activated carbon adsorption layer can be formed in the middle of the adsorption box 25. The liquid after the initial distillation flows from the interior of the distillation box 21 into the upper side of the interior of the adsorption box 25 through the water pump a27 and the delivery pipe b26. Under the action of gravity, the liquid penetrates from the activated carbon adsorption layer into the lower side of the partition b28, and is then discharged and collected through the drain port 40. The activated carbon can be used to adsorb organic impurities such as surfactant decomposition products in the anti-caking liquid on the surface of the activated carbon, further purifying the anti-caking liquid, improving its quality, and reducing the impact of organic impurities on the anti-caking effect of ammonium perchlorate crystals. As a supplement to other processing modules, the adsorption module can remove some trace impurities that cannot be completely removed during the filtration, ion exchange and distillation processes, thereby improving the purity of the anti-caking liquid and ensuring that it meets high quality standards.

[0068] An inspection port 34 is provided in the middle of the main body 1, and the inspection port 34 is connected to the equipment box 19, which is mainly used to facilitate management personnel to inspect and repair the equipment inside the equipment box 19;

[0069] Example 2: This example is a further description of an ammonium perchlorate crystal anti-liquidation treatment device in Example 1, and mainly introduces a method for treating ammonium perchlorate crystals to prevent liquidation. The specific steps are as follows:

[0070] Step 1: Introduce waste liquid. Start the water pump b32 in the equipment box 19 to discharge the waste liquid into the liquid feeding box 2 through the water inlet pipe 31. At this time, the liquid feeding plate 6 is located on the upper side of the liquid feeding box 2.

[0071] Step 2, liquid feeding operation, when the waste liquid fills the interior of the liquid feeding box 2, the motor 4 at the top of the main body 1 is turned on; the motor 4 drives the threaded rod 3 at the output end to rotate. Since the threaded rod 3 is threadedly connected to the liquid feeding plate 6, and the liquid feeding plate 6 is restricted by the two slide bars a5 and cannot rotate, the threaded rod 3 drives the liquid feeding plate 6 to move downward in the liquid feeding box 2; the liquid feeding plate 6 squeezes the liquid in the box, and the liquid is discharged into the upper side of the liquid feeding plate 6 through the infusion hole 7. The hydraulic pressure lifts the sealing plate 9 and opens the channel of the infusion hole 7; when the liquid feeding plate 6 moves to the bottom of the liquid feeding box 2, the motor 4 reverses, driving the liquid feeding plate 6 to move upward, and the hydraulic pressure causes the sealing plate 9 to move downward to block the infusion hole 7. The liquid flows into the filter box 10 under the pressure of the liquid feeding plate 6;

[0072] Step 3: Primary filtration: As the liquid flows into the filter box 10, it is initially filtered through the filter element 11. The filter element 11 is fixed in the box by the clamping block 12 at the top and the clamping slot 13 in the filter box 10. The primary filtration can intercept larger ammonium perchlorate particles, dust and other mechanical impurities in the ammonium perchlorate crystal-preventing liquid. The filtered liquid is discharged into the exchange box 15 through the drainage hole 14 at the top edge of the filter box 10.

[0073] Step 4: Ion exchange. Ion exchange resin is added in advance between the two partitions a16 in the exchange box 15 through the feed port a17 to form an ion exchange layer. The liquid flowing into the upper side of the exchange box 15 from the drain hole 14 penetrates the ion exchange layer and enters the lower side under the action of gravity. The ion exchange resin absorbs metal ions such as iron ions, copper ions, and zinc ions in the anti-caking liquid through the ion exchange reaction, thereby reducing the metal ion content. Because the two partitions a16 are arranged at an angle, the used ion exchange resin can be discharged through the discharge port a18 under the action of gravity, making it easy to replace.

[0074] Step 5: The liquid is transported to the distillation box 21. The solenoid valve 35 in the middle of the delivery pipe a20 is opened to transport the treated liquid at the bottom of the exchange box 15 to the inside of the distillation box 21 through the delivery pipe a20.

[0075] Step 6: Distillation operation. Close the sealing valve 39 and the solenoid valve 35 to seal the distillation chamber 21. Turn on the electric heating plate 22 to heat the liquid in the chamber. Simultaneously, the temperature in the chamber is monitored in real time by the temperature sensor 36, and the pressure in the chamber is monitored by the pressure sensor 37. Start the vacuum pump 38 to create a vacuum in the distillation chamber 21. Utilize the differences in boiling points of different substances to separate water and some impurities with boiling points significantly different from those of ammonium perchlorate and the active ingredient in the anti-condensation liquid. The vaporized impurities condense on multiple staggered, tilted condensation plates 23. The condensed liquid is collected in the grooves formed by the bottom condensation plate 23 and the inner wall of the distillation chamber 21 and discharged through the drain pipe 24. The distillation process concentrates the active ingredients in the anti-condensation liquid and removes excess water or low-boiling-point impurities.

[0076] Step 7: The liquid is transported to the adsorption box 25. The water pump a27 is started to transport the liquid after the initial distillation at the bottom of the distillation box 21 to the top of the adsorption box 25 through the delivery pipe b26.

[0077] In step 8, adsorption operation, activated carbon adsorbent is added in advance through the feed port b29 into the space between the two partitions b28 in the adsorption box 25 to form an activated carbon adsorption layer. Under the action of gravity, the liquid penetrates the activated carbon adsorption layer and enters the lower side of the partition b28, and is finally discharged and collected through the drain port 40. The activated carbon adsorbent absorbs organic impurities such as surfactant decomposition products and other trace impurities in the anti-caking liquid, thereby further purifying the anti-caking liquid.
