Description

Technical Field

[0001] This utility model relates to the field of detection technology, and in particular to a rapid detection device for ammonium perchlorate purity. Background Technology

[0002] Ammonium perchlorate is an important chemical raw material widely used in explosives manufacturing, fireworks production, and the aerospace industry. Its purity directly affects the quality and performance of the products. Therefore, it is particularly important to quickly and accurately detect the purity of ammonium perchlorate.

[0003] Traditional ammonium perchlorate purity testing devices often rely on manual operation or simple mechanical structures for sample processing, particularly in the feeding stage. Manual feeding is greatly affected by the operator's subjective factors, such as fatigue level, skill level, and differences in adherence to operating procedures, which can lead to significant deviations in the amount fed each time. Even in some devices that use mechanical feeding, the feeding amount is difficult to guarantee a high degree of consistency due to the lack of precise control and measurement methods. Therefore, we propose a rapid ammonium perchlorate purity testing device. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a rapid detection device for ammonium perchlorate purity, comprising:

[0027] Purity testing chamber 1, with a sliding groove 19 on the bottom wall of the inner side of the purity testing chamber 1, and a mixing tank 3 is installed inside the purity testing chamber 1;

[0028] The discharge structure is detected on the purity testing chamber 1.

[0029] The discharge structure includes two electric lifting rods 11, a sealing cover 13, a weight sensor 7, and a storage tank 9. The two electric lifting rods 11 are fixedly installed on the inner top wall of the purity testing chamber 1. The telescopic ends of the two electric lifting rods 11 are fixedly connected to the top of the sealing cover 13. The weight sensor 7 is fixedly installed on the top of the sealing cover 13. The storage tank 9 is fixedly installed on the top of the weight sensor 7. The discharge end of the storage tank 9 passes through the interior of the weight sensor 7 and through the sealing cover 13. A solenoid valve 8 is fixedly installed on the discharge end of the storage tank 9.

[0030] The discharge detection structure also includes a drive motor 10, a rotating shaft 16, and a discharge screw 15. The drive motor 10 is fixedly installed on the top of the storage tank 9. The output end of the drive motor 10 rotates through the top of the storage tank 9 and is fixedly connected to the rotating shaft 16. The discharge screw 15 is fixedly wound around the outer surface of the rotating shaft 16.

[0031] A liquid inlet pipe 12 is fixedly installed on the top of the sealing cover 13, and the bottom end of the liquid inlet pipe 12 penetrates the sealing cover 13.

[0032] A stirring motor 14 is fixedly installed on the top of the sealing cover 13. The output end of the stirring motor 14 rotates through the sealing cover 13 and is fixedly connected to the stirring roller 6. Two guide rails 4 are fixedly connected to the inner bottom wall of the purity detection box 1. Limiting slide plates 20 are slidably connected inside the two guide rails 4. A moving platform 2 is fixedly connected to the top of the two limiting slide plates 20. The mixing tank 3 is placed on the top of the moving platform 2.

[0033] A regulating motor 5 is fixedly installed on one side of the purity testing box 1. The output end of the regulating motor 5 extends into the interior of the sliding groove 19 and is fixedly connected to a threaded rod 17. The threaded rod 17 is rotatably connected to the interior of the sliding groove 19. A sliding block 18 is fixedly connected to the bottom of the moving table 2. The sliding block 18 is threaded onto the outer surface of the threaded rod 17 and is slidably connected to the interior of the sliding groove 19.

[0034] Furthermore, when using this device, by connecting an external power source to start the two electric lifting rods 11, the two electric lifting rods 11 will drive the sealing cover 13 to move downwards, and the sealing cover 13 will come into contact with the top of the mixing tank 3, thereby facilitating the movement of the stirring roller 6 into the interior of the mixing tank 3. Subsequently, by connecting an external power source to start the drive motor 10 and the solenoid valve 8, the weight sensor 7 will detect the weight of the ammonium perchlorate in the storage tank 9. When the ammonium perchlorate in the storage tank 9 is discharged, the solenoid valve 8 will open. Subsequently, the drive motor 10 will drive the rotating shaft 16 to rotate, and the rotating shaft 16 will drive the discharge screw 15 to rotate, thereby facilitating the discharge of ammonium perchlorate from the storage tank 9 into the mixing tank 3. However, when the discharge of ammonium perchlorate requires weight, the weight sensor 7 will control the solenoid valve 8 to close, thereby facilitating the quantitative discharge of ammonium perchlorate into the mixing tank 3, so that deionized water can be added into the mixing tank 3 through the liquid inlet pipe 12 to mix with the ammonium perchlorate.

[0035] Furthermore, when using this device, the stirring motor 14 is started by connecting an external power source. The stirring motor 14 drives the stirring roller 6 to rotate. The rotation of the stirring roller 6 mixes the ammonium perchlorate with the deionized water, thereby accelerating the detection of the purity of the ammonium perchlorate. When it is necessary to discharge the mixed ammonium perchlorate in the mixing tank 3, the regulating motor 5 is started by connecting an external power source. The regulating motor 5 drives the threaded rod 17 to rotate. The rotation of the threaded rod 17 drives the sliding block 18 to move horizontally under the guidance of the sliding groove 19, thereby facilitating the movement of the moving stage 2. The movement of the moving stage 2 causes the two limiting slide plates 20 to slide inside the corresponding guide rails 4, so that the moving stage 2 can discharge the mixed tank 3, thereby facilitating subsequent titration detection.

[0036] A controller is fixedly installed on one side of the purity testing box 1. The weight sensor 7 is installed at the bottom of the storage tank 9 to monitor the weight of the material in the tank in real time. It converts the weight signal into a standard electrical signal and transmits it to the controller.

[0037] Controller: Receives the electrical signal from the weight sensor 7 and compares it with the preset weight threshold. Based on the comparison result, the controller outputs a control signal to the solenoid valve 8. The controller can be a programmable logic controller.

[0038] Solenoid valve 8: Installed on the discharge pipe of storage tank 9, it controls the opening and closing of the discharge pipe according to the control signal sent by the controller. When it receives the open signal, solenoid valve 8 opens and the material begins to be discharged; when it receives the close signal, solenoid valve 8 closes and stops discharging.

[0039] With the cooperation of weight sensor 7, solenoid valve 8, storage tank 9, rotating shaft 16 and discharge screw 15, weight sensor 7 can control the opening and closing of solenoid valve 8. When the required weight of ammonium perchlorate is discharged from storage tank 9, weight sensor 7 can control solenoid valve 8 to close, which facilitates the quantitative feeding of ammonium perchlorate. This allows for accurate metering of ammonium perchlorate and further improves the feeding speed of ammonium perchlorate during testing.

[0047] Storage tank 9: Used to store ammonium perchlorate samples to be tested, and its discharge into mixing tank 3 is controlled by solenoid valve 8;

[0048] Electric lifting rod 11: It drives the sealing cover 13 to move up and down through telescopic movement, thereby controlling the closing and opening of the mixing tank 3;

[0049] Inlet pipe 12: Used to inject reaction liquid or other required liquids into mixing tank 3;

[0050] Discharge screw 15: Rotates under the drive of drive motor 10, and evenly conveys the material in storage tank 9 to discharge end;

[0051] Rotating shaft 16: connects drive motor 10 and discharge screw 15 to transmit power;

[0052] Threaded rod 17: Rotates under the drive of adjusting motor 5, and drives sliding block 18 and its moving table 2 to move through threaded connection;
