Description

Technical Field

[0001] This utility model relates to the field of ammonium perchlorate production technology, and in particular to a monitoring device for the ammonium perchlorate reaction process. Background Technology

[0002] Ammonium perchlorate is a white crystalline solid with deliquescent properties. It is a strong oxidizing agent and can explode when mixed with reducing agents, organic matter, flammable materials such as sulfur, phosphorus, or metal powders. Contact with strong acids poses a risk of combustion and explosion. Liquid crystallization is required during the production of ammonium perchlorate. Chinese utility model patent, authorization announcement number "CN220455726U", discloses an automatic temperature control device for refined ammonium perchlorate liquid, including a heating tank. A slip ring is slidably mounted on the outside of the heating tank. A groove is formed on the lower surface of the slip ring, and a slider is slidably connected inside the groove. A bracket with a U-shaped structure is fixedly connected to the bottom of the slider. A fixing plate is fixedly connected to the bottom of the bracket, and a temperature sensor is fixedly connected to the bottom of the fixing plate. A drive assembly for moving the temperature sensor is located below the slip ring.

[0003] The above-mentioned technical solution involves a motor rotating to drive a gear. Because the gear meshes with the toothed block, the slider slides inside the groove, which in turn drives a temperature sensor to move around the outside of the heating tank via a bracket and a fixing plate. This allows for multi-position temperature monitoring of the heating tank, eliminating the need for manual control and improving the accuracy of temperature control. However, the above-mentioned technical solution still has certain drawbacks. Only temperature is monitored during the ammonium perchlorate solution production reaction, neglecting other key parameters. Temperature has a coupling effect with parameters such as pH and concentration, making precise control difficult with single monitoring and easily affecting the accuracy of the detection data during the ammonium perchlorate reaction. Therefore, this utility model proposes a novel solution. Utility Model Content

An anode 4 and a cathode 5 are fixedly connected inside the electrolysis tank 2. The lower ends of the anode 4 and the cathode 5 are both spiral-shaped, and ceramic sleeves are installed at the positions where the anode 4 and the cathode 5 contact the electrolysis tank 2.

[0034] The first drive motor 7, rotating shaft 8, spiral stirring blade 9, exhaust pipe 10, temperature sensor 11, oxidation-reduction potential monitoring probe 12, and pH sensor 13 are all arranged in two sets, respectively inside the electrolytic tank 2 and the ammonium perchlorate reactor 3.

[0035] Both the electrolysis tank 2 and the ammonium perchlorate reactor 3 are fixedly connected to the upper end of a feed pipe, and both the electrolysis tank 2 and the ammonium perchlorate reactor 3 are fixedly connected to the lower end of a discharge pipe.

[0036] A reaction chamber 17 is fixedly connected to the upper end of the base 1. A placement box 23 is fixedly connected inside the reaction chamber 17. A through hole is opened on the surface of the placement box 23. Manganese dioxide particles are placed inside the placement box 23.

The end of the second inlet pipe 19 away from the second centrifugal pump 18 extends into the interior of the second inlet pipe 19. A second outlet pipe 20 is fixedly connected to the water outlet end of the second centrifugal pump 18. The end of the second outlet pipe 20 away from the second centrifugal pump 18 extends into the interior of the ammonium perchlorate reaction vessel 3.

[0039] The control box 22 contains a processor that processes the temperature sensor 11, the redox potential monitoring probe 12, and the pH sensor 13.

[0040] When using this device, sodium chlorate is electrolyzed in electrolytic tank 2 using a platinum electrode as the anode and a stainless steel electrode as the cathode. Sodium chlorate is converted into sodium perchlorate under electrolysis. At the same time, potassium chromate is added to inhibit cathode reduction and ensure that the electrolysis reaction proceeds in the direction of sodium perchlorate production. Since the lower ends of anode 4 and cathode 5 are both spiral-shaped, it is easy to increase the contact area between anode 4 and cathode 5 and the solution, which facilitates the increase of reaction rate. The first centrifugal pump 14 is started, and the sodium perchlorate solution generated in electrolytic tank 2 is extracted through the first water inlet pipe 15 and transported to ammonium perchlorate reactor 3 through the first water outlet pipe 16, providing key raw materials for the subsequent reaction to generate ammonium perchlorate.

[0041] The first drive motor 7 at the top of the ammonium perchlorate reactor 3 starts, driving the connected rotating shaft 8 to rotate. The rotating shaft 8 is rotatably connected to the fixed frame 6 to ensure the stability of the rotation. The spiral stirring blades 9 fixed on the rotating shaft 8 rotate accordingly. The two spiral stirring blades 9 with opposite spiral directions can fully mix the materials in the reactor, accelerate the chemical reaction, ensure full contact between reactants, and improve reaction efficiency. The temperature sensor 11, the oxidation-reduction potential monitoring probe 12, and the pH sensor 13 monitor the reaction in the ammonium perchlorate reactor 3 in real time. The temperature sensor 11 monitors the temperature change during the reaction process, the oxidation-reduction potential monitoring probe 12 detects the oxidation-reduction potential of the reaction system, and the pH sensor 13 monitors the acidity and alkalinity of the reaction solution. These data are transmitted in real time to the processor in the control box 22. The processor analyzes and processes these data. Once it finds that a parameter deviates from the preset range, it will issue an instruction to adjust the reaction conditions. For example, if the temperature is too high, the processor can control the first drive motor 7 to reduce the speed and reduce the heat generated by stirring. If the pH value does not meet the reaction requirements, the acidity and alkalinity of the reaction solution can be adjusted by controlling the feed rate of the feed pipe.

[0042] During the reaction of ammonium perchlorate, gas is generated. The exhaust pipe 10 is fixed at the upper end of the ammonium perchlorate reactor 3 to discharge the gas generated in the reaction in a timely manner, maintain the stable gas pressure in the reactor, avoid safety problems caused by excessive gas pressure, and ensure that the reaction can proceed smoothly in a safe environment.

[0043] Ammonia water is introduced into the ammonium perchlorate reactor 3 to react with the sodium perchlorate that was previously introduced, generating ammonium perchlorate. The solution inside reactor 3 is stirred by the spiral stirring blade 9 to promote the reaction between sodium perchlorate and ammonia water. The pH of the reaction solution is monitored again by the pH sensor 13.

[0044] Then, concentrated hydrochloric acid and hydrogen peroxide are introduced into the interior of the ammonium perchlorate reactor 3 after the reaction to convert the residual sodium chlorate into chlorine dioxide gas and neutralize the excess ammonia. Since the solution still contains hydrogen peroxide, the manganese dioxide placed in the placement box 23 in the reaction tank 17 plays an important role. The manganese dioxide comes into contact with the hydrogen peroxide through the through holes on the surface of the placement box 23 to remove impurities from the hydrogen peroxide, thereby improving the purity of the reaction raw materials and thus improving the quality of the ammonium perchlorate production. The second centrifugal pump 18 is started, and the substances (including the components that participate in the reaction and remove impurities) in the reaction tank 17 are drawn through the second water inlet pipe 19 and transported to the ammonium perchlorate reactor 3 through the second water outlet pipe 20, continuously providing the necessary substances for the reaction and ensuring the continuity and stability of the reaction.

[0045] After the reaction is complete, the ammonium perchlorate solution is discharged through the discharge pipe at the lower end of the ammonium perchlorate reactor 3 for subsequent processing. Electrolysis tank 2 and ammonium perchlorate reactor 3 can be replenished with new raw materials through the feed pipe at the upper end to prepare for the next reaction. Throughout the reaction process, the various components cooperate with each other, and the control box 22 precisely regulates the reaction based on monitoring data to ensure that the ammonium perchlorate reaction proceeds safely, efficiently, and stably. At the same time, the equipment is regularly maintained and inspected to ensure that all components operate normally, especially key components such as electrodes and sensors, in order to maintain the monitoring and reaction performance of the device.

[0046] Furthermore, the temperature sensor 11, the redox potential monitoring probe 12, the pH sensor 13, and the spiral stirring blade 9 work together in the ammonium perchlorate reaction process. The spiral stirring blade 9 has two blades with opposite spiral directions fixed on its surface. Driven by the first drive motor 7, the rotating shaft 8 rotates, causing the spiral stirring blade 9 to rotate accordingly. This special design allows the reactants in the ammonium perchlorate reactor 3 to be fully mixed, increasing the contact area between the reactants and accelerating the reaction rate. The temperature sensor 11, the redox potential monitoring probe 12, and the pH sensor 13 transmit monitoring data to the processor in the control box 22, facilitating the monitoring of the ammonium perchlorate reaction process, ensuring the stable operation of the entire device, improving the accuracy of the detection data, and providing a guarantee for the continuous production of ammonium perchlorate.
