Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to a moisture-proof and sealed storage device for ammonium perchlorate. Background Technology
[0002] Ammonium perchlorate, as an important chemical raw material, has wide applications in many fields, such as serving as a key oxidant component in aerospace propellants and being used in the pyrotechnics industry to formulate special pyrotechnic agents. However, ammonium perchlorate has strong hygroscopic properties. Once it absorbs moisture from the air, it not only reduces its purity and alters its chemical properties but may also cause clumping, seriously affecting its subsequent use. In some extreme cases, the chemical reactions caused by moisture absorption may even pose safety hazards.
[0003] Existing ammonium perchlorate storage devices mostly focus on physical sealing of storage tanks, using rubber sealing rings, threaded connections, and other methods to isolate them from the outside air. To improve the storage environment of ammonium perchlorate, some storage devices have attempted to introduce desiccants to assist in moisture prevention. However, most of these designs place the desiccant outside the storage tank, hoping to create a low-humidity external environment to indirectly protect the ammonium perchlorate inside the tank by setting up desiccant packs around the tank. However, external desiccants are greatly affected by environmental interference, making it difficult to accurately control their impact on the humidity inside the tank. Furthermore, once the desiccant is saturated with moisture, it cannot provide continuous moisture protection to the inside of the tank in a timely manner, thus reducing the practicality of the equipment. Utility Model Content
[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a moisture-proof and sealed storage device for ammonium perchlorate. This device can solve the problem of placing desiccant outside the storage tank and setting up desiccant packs around the tank to create a low-humidity external environment to indirectly protect the ammonium perchlorate inside the tank. However, the external desiccant is greatly affected by the environment and it is difficult to accurately control its impact on the humidity inside the tank. Moreover, once the desiccant is saturated with moisture, it cannot provide continuous moisture protection for the inside of the tank in a timely manner, thus reducing the practicality of the device.

Push block grooves 19 are formed on the upper surfaces of both sides of the protective cover 5. Both limiting and fixing brackets 6 are fixedly connected to the upper surface of the can lid 7. Two push blocks 16 are slidably connected inside each of the two push block grooves 19. Second limiting block grooves 18 are formed on the inner walls of both sides of the two limiting and fixing brackets 6. Two first limiting block grooves 12 are formed on the outer walls of both sides of the protective cover 5. Limiting blocks 14 are slidably connected inside each of the four first limiting block grooves 12. A desiccant placement groove 17 is formed on the upper surface of the can lid 7. The lower outer wall of the protective cover 5 is slidably connected to the interior of the desiccant placement groove 17. The outer walls of both sides of the protective cover 5 are slidably connected to the interior of the corresponding limiting and fixing brackets 6. The two limiting blocks 14 are close to... One end of each of the second limiting block grooves 18 slides to the outside of the protective cover 5 and contacts the inner wall of the corresponding second limiting block groove 18. The outer wall of the sealing ring installed at the lower end of the protective cover 5 contacts the inner wall of the desiccant placement groove 17. The interior of each of the four first limiting block grooves 12 communicates with the interior of the corresponding two push block grooves 19. One end of each of the four push blocks 16 near the limiting block 14 slides to the interior of the first limiting block groove 12 and is fixedly connected to the outer wall of the corresponding limiting block 14. Each of the two push block grooves 19 is provided with a return spring 11. The two ends of the two return springs 11 are fixedly connected to the outer wall of one side of the corresponding push block 16. The lower outer wall of the can cover 7 slides to the interior of the upper opening of the storage tank 1. The interior of the desiccant placement groove 17 communicates with the interior of the storage tank 1.
[0033] Each of the two pusher slots 19 has a rubber limiting block 15 inside. The two ends of the two rubber limiting blocks 15 contact the outer wall of one side of the corresponding pusher 16. The outer wall of the sealing ring installed at the lower end of the tank cover 7 contacts the inner wall of the storage tank 1. Three mounting seats 10 are fixedly connected to the outer wall of the storage tank 1. The outer walls of the two side plates of the three mounting seats 10 are provided with sliding grooves 2. The three fixed brackets 3 are all L-shaped. The outer walls of the two side plates of the three mounting seats 10 are provided with fixing rod grooves 9. The outer walls of the fixing rods at the lower end of the three fixed brackets 3 slide in the inner wall of the corresponding sliding grooves 2. The can lid 7 has three grooves on its upper surface, each with a fixing bolt groove 13. The upper outer walls of the three fixing brackets 3 are fixedly connected to fixing rods 8.

[0034] Furthermore, when using the device, when it is necessary to place or replace the desiccant, push the push block 16.

The limiting block 14 slides back into the second limiting block groove 18 to fix the protective cover 5, prevent desiccant leakage, and ensure the sealing of the desiccant placement groove 17 so that it can effectively absorb the moisture in the storage tank 1, maintain the internal dry environment, and protect the ammonium perchlorate from moisture. Then, when it is necessary to remove the can cover 7, turn the fixing bolt 4 to rotate so that the outer wall of its other end is disengaged from the inside of the fixing bolt groove 13. Then, pull the fixing bracket 3 to make it rotate around the sliding groove 2 while disengaging its upper end from the groove on the can cover 7. Then, pull the can cover 7 to remove it from the storage tank 1.
[0035] By pushing the pusher 16 in the storage device to slide in the pusher groove 19 and compress the return spring 11, the limiting block 14 is driven to slide in the first limiting block groove 12, so that the limiting block 14 is disengaged from the second limiting block groove 18. At this time, the protective cover 5 can be slid upward along the limiting fixing frame 6 and taken out. After placing the desiccant in the desiccant placement groove 17, it can effectively absorb the moisture in the storage tank 1, maintain the internal dry environment, protect the ammonium perchlorate from moisture, and reduce the impact of external buffer on the desiccant pack, thereby improving the practicality of the equipment.
