A discharge port is located at the bottom of the drying chamber, and a solenoid valve is installed at the bottom of the discharge port. A second hollow shaft is connected to the top of the drying chamber via a bearing. A feed hopper is installed at the right end of the top of the drying chamber. A drive assembly is located between the second hollow shaft and the drying chamber. A hot air conveying assembly is located at the top of the second hollow shaft, and the bottom of the second hollow shaft extends into the lower end of the drying chamber's inner cavity. This application utilizes a combination of an exhaust pipe, a purification chamber, a second fan, an activated carbon adsorption screen, a filter screen, and an air inlet pipe. Harmful gases enter the purification chamber through the air inlet pipe and undergo double filtration through the filter screen and activated carbon adsorption screen, minimizing the possibility of workers accidentally inhaling harmful substances and reducing environmental pollution.

[0004] However, the above-mentioned device still has shortcomings. During use, the device cannot classify and process samples with different testing requirements. For example, it cannot simultaneously meet the two different needs: a small number of samples with high-precision testing requirements and a large number of samples with routine testing requirements. It can only perform uniform drying treatment on the samples and cannot flexibly adjust according to the specific conditions of the samples. This limits its applicability and testing efficiency to a certain extent.

[0005] Therefore, it is necessary to propose a device for measuring the water content of ammonium perchlorate to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a device for determining the moisture content of ammonium perchlorate, in order to solve the problems mentioned in the background art, that traditional drying ovens can only dry large quantities of samples and that it is inconvenient to adjust the position of samples when they are placed on the drying oven.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for determining the moisture content of ammonium perchlorate, comprising a drying oven for drying ammonium perchlorate, wherein a detection structure is provided inside the drying oven by pushing and pulling.

[0025] This invention provides a device for determining the moisture content of ammonium perchlorate. Please refer to the appendix. Figure 1 - Appendix Figure 4 As shown.

[0026] The equipment includes a drying oven 1 for drying ammonium perchlorate. The interior of the drying oven 1 features a push-pull design and a movable detection structure. This design allows the detection structure to easily enter and exit the drying oven 1 as needed, facilitating sample placement and removal, as well as maintenance and cleaning of the detection structure.

[0027] The detection structure consists of multiple parts, including a base plate 7, a support plate 8, and a detection box 15. The base plate 7 serves as the foundation of the entire structure, and multiple support blocks 14 are fixedly installed on its upper surface. These support blocks 14 are used to support the support plate 8. Multiple detection boxes 15 are evenly distributed on the support plate 8. Each detection box 15 can independently hold ammonium perchlorate samples. This layered design makes the sample placement more orderly and facilitates management and operation.

[0028] The design of multiple testing chambers 15 allows for the simultaneous placement of multiple samples, improving testing efficiency and facilitating the differentiation and management of different samples. Each testing chamber 15 can be operated independently, making it convenient to dry and test different samples separately, thus avoiding cross-contamination between samples.

[0029] The support plate 8 is designed with multiple adjustment slots 17, and an adjustment block 18 is installed in each adjustment slot 17. The adjustment block 18 is connected to the support plate 8 through a threaded rod 19. The threaded rod 19 passes through the adjustment block 18 and the support plate 8, and adjustment bolts 20 are fixedly installed at both ends. By rotating the adjustment bolts 20, the position of the adjustment block 18 in the adjustment slot 17 can be adjusted, thereby realizing the fine adjustment of the detection box 15.

[0030] By adjusting bolt 20, the position of the testing chamber 15 can be precisely adjusted to ensure that the sample is heated evenly during the drying process. The fine-tuning function can ensure the positional accuracy of each testing chamber 15 during the drying process, further improving the consistency of the drying effect.

[0031] The base plate 7 has a pull-out plate 16 inside, which can be easily pulled out or pushed in from the base plate 7. The pull-out plate 16 has multiple placement cavities 21, each of which corresponds to the position of the detection box 15. This design makes it easier to place and remove samples, and also makes it easier to clean and maintain the pull-out plate 16.

[0032] The sample placed in the placement chamber 21 is in a flat state, which is suitable for scenarios with high requirements for detection accuracy, small sample volume, and need for rapid drying. For example, when performing accurate moisture content detection on a small amount of ammonium perchlorate sample in the laboratory, flat placement can ensure that the sample is heated evenly, reduce drying time, and improve detection accuracy.

[0033] The samples placed in the testing chamber 15 are in a stacked state, which is suitable for scenarios that require processing a large number of samples or thicker samples. For example, in industrial production, when a large number of ammonium perchlorate samples are dried in batches, stacking can make full use of the space in the drying chamber 1, improve production efficiency, and thus conduct comprehensive testing on this batch of samples produced in the factory, improve the comprehensiveness of the testing, ensure the consistency and stability of product quality, provide reliable data support for subsequent production processes, and optimize production parameters to reduce production delays and economic losses caused by quality problems.

[0034] A slide table 5 is installed below the base plate 7. The slide table 5 is designed with two sliding grooves 6. The function of the slide table 5 is to smoothly send the base plate 7 and the detection structure on it into or out of the drying chamber 1. The design of the sliding grooves 6 ensures the stability and accuracy of the base plate 7 during the sliding process.

[0035] Rollers 13 are installed on the lower surface of the base plate 7. These rollers 13 are located in the slide groove 6 and slide within the slide groove 6. The design of the rollers 13 makes the movement of the base plate 7 smoother, reduces friction, and improves the convenience and efficiency of operation.

[0036] The drying oven 1 has a partition plate 10 installed inside. The partition plate 10 has multiple holes 11 evenly distributed on it. The design of the holes 11 allows heat to pass through the partition plate 10 evenly, avoiding the problems of local overheating or incomplete drying. This uniform heat distribution ensures that the sample is heated evenly throughout the drying process, reducing the uneven drying caused by local temperature differences.

[0037] The design of the partition plate 10 not only considers the uniformity of heat distribution, but also takes into account the flexibility and stability of the structure. Near the two sides of the partition plate 10, there are specially opened passage slots 12. The design of the two passage slots 12 allows the support block 14 to pass through smoothly, thereby ensuring that the detection structure (including the base plate 7, the support plate 8 and the detection box 15) can be pushed and pulled smoothly in the drying box 1. This design not only optimizes the use of space, but also improves the convenience of operation and the overall stability of the equipment.

[0038] To further optimize the drying process, multiple heating elements 9 are evenly distributed on the inner wall of the drying chamber 1. The design of these heating elements 9 ensures the uniform distribution of heat inside the drying chamber 1, avoiding problems such as local overheating or uneven temperature. By precisely controlling the power and temperature of the heating elements 9, the drying process can be accurately controlled, thereby improving drying efficiency and sample drying quality.

[0039] To ensure the airtightness and automated operation of the drying process, a gantry frame 2 is installed between the drying chamber 1 and the slide table 5. A hydraulic lifting column 3 is installed on the gantry frame 2, and the output end of the hydraulic lifting column 3 is connected to the sealing door 4. Through the hydraulic system, the sealing door 4 can be automatically raised and lowered to achieve rapid sealing and opening of the drying chamber 1. This design not only improves the convenience and efficiency of operation, but also ensures the airtightness of the drying process, preventing moisture in the outside air from entering the drying chamber 1 and affecting the drying effect.

[0040] During use, check whether the drying oven 1, slide table 5, gantry frame 2, hydraulic lifting column 3, sealing door 4 and other components are operating normally to ensure that the equipment is in good condition. Remove the base plate 7, support plate 8, detection box 15 and pull plate 16 and other components for thorough cleaning to ensure that there are no residual samples or impurities. Prepare a high-precision electronic balance and calibrate it to ensure that the measurement results are accurate and reliable. Weigh the ammonium perchlorate sample to be tested and record the initial mass of the sample.

[0041] During use, if it is necessary to accurately test the moisture content of a small amount of ammonium perchlorate sample, the sample is laid flat in the placement cavity 21 of the pull-out plate 16. Laying it flat can ensure that the sample is heated evenly, reduce drying time, and improve detection accuracy. If it is necessary to dry a large number of ammonium perchlorate samples in batches, the samples are stacked in the detection chamber 15. Stacking can make full use of the space of the drying chamber 1, improve production efficiency, and ensure that the entire batch of samples is fully tested, depending on the placement of the samples.

[0042] By rotating the adjusting bolt 20, the position of the adjusting block 18 within the adjusting groove 17 is adjusted to ensure the positional accuracy of the detection box 15 during the drying process, further improving the consistency of the drying effect. The detection structure is pushed into the drying chamber 1, ensuring its accurate position. The hydraulic lifting column 3 is operated to lower the sealing door 4 and tightly seal the drying chamber 1. The heating element 9 on the inner wall of the drying chamber 1 is turned on. Based on the properties of ammonium perchlorate and the initial moisture content of the sample, a suitable drying temperature is set, typically 105℃±2℃. By precisely controlling the power and temperature of the heating element 9, the heat distribution inside the drying chamber is ensured to be uniform, avoiding local overheating or incomplete drying. During the drying process, the condition of the sample is observed through the observation window on the drying chamber 1. To ensure the sample remains dry without any abnormalities, the temperature and time data during the drying process are recorded. When the sample's moisture content reaches the predetermined requirement or the drying time reaches the predetermined value, the heating element 9 is turned off to stop the drying process. The sealing door 4 is opened, and the detection structure is pulled out of the drying chamber 1 and placed in a well-ventilated area to allow the sample to cool naturally to room temperature. During the cooling process, the sample is protected from external moisture contamination. The cooled sample is then removed from the detection chamber 15 or the placement chamber 21 and weighed on a high-precision electronic balance. The final mass of the sample is recorded. The initial mass, final mass, drying temperature, drying time, and calculated moisture content are recorded in the experimental report.
