[0002] Ammonium perchlorate is a white crystal, has deliquescence, and is a strong oxidant. Mixing with reducing agents, organic matter, flammable materials such as sulfur, phosphorus or metal powder, etc. will cause explosion. Contact with strong acid will cause burning explosion. Ammonium perchlorate needs drying treatment. Ammonium perchlorate has strong hygroscopicity, easily absorbs moisture in the air, and causes changes in its performance. Specifically, ammonium perchlorate will absorb moisture in a humid environment, causing changes in its chemical properties, which may affect its combustion performance and stability.

[0003] The existing ammonium perchlorate drying device mainly dries through a high-temperature vibration dryer or natural drying methods such as sunlight irradiation. However, it is generally not conducive to controlling the temperature during the drying process. Ammonium perchlorate is prone to decomposition and release of harmful gases when the temperature exceeds a certain value, and its strong oxidizing property will intensify the reaction intensity. If the temperature is out of control during the drying process, it may cause burning or even explosion. If the temperature inside the drying box is uneven, local overheating or insufficient heating may occur, resulting in clumping, which requires an additional mechanical crushing process, increasing energy consumption and time cost. Therefore, a drying process temperature control device for ammonium perchlorate is needed. SUMMARY

[0022] In the description of the present application, unless otherwise explicitly limited, the words such as setting, installing and connecting should be understood in a broad sense, and the skilled in the art can reasonably determine the specific meaning of the above words in the present application in combination with the specific content of the technical scheme.

[0023] Please refer to Figures 1-4 The present application provides a technical scheme: an ammonium perchlorate drying process temperature control device, which comprises a drying box 1 and a uniform drying mechanism, the uniform drying mechanism comprises a wind box 3, a motor 6, a rotating roller 11, a conveyor belt 12, a conveying plate 13, a filter screen 16 and a fan 17, the wind box 3 is fixedly connected to the surface of the drying box 1, the motor 6 is fixedly connected to the surface of the drying box 1, the rotating roller 11 is rotatably connected to the inside of the drying box 1, the output end of the motor 6 extends to the inside of the drying box 1 and is fixedly connected with the rotating roller 11, the number of the rotating roller 11 is two and both are located in the inside of the drying box 1, the conveyor belt 12 is sleeved on the outer surfaces of the two rotating rollers 11, the number of the conveying plate 13 is multiple and is equidistantly fixedly connected to the surface of the conveyor belt 12, the filter screen 16 is fixedly connected to the surface of the drying box 1, the drying box 1 is connected with the inside of the wind box 3 through the filter screen 16, and the fan 17 is fixedly connected to the inside of the wind box 3.

[0024] Furthermore, the drying chamber 1 has a drying chamber 15 inside. The conveyor plate 13 is in contact with the drying chamber 1 on the side near the inner wall of the drying chamber 1. A heating shell 5 is fixedly connected to the surface of the drying chamber 1. A controller 7 is fixedly connected to the top of the heating shell 5. Multiple heating plates 8 are fixedly connected to the surface of the heating shell 5. The surface of the drying chamber 1 has the same number of slots 9 as the heating plates 8. Each heating plate 8 is located inside the corresponding slot 9. A feed hopper 4 is fixedly connected to the top of the drying chamber 1. A feed inlet 10 adapted to the feed hopper 4 is opened on the surface of the drying chamber 1. Multiple device supports 2 are fixedly connected to the bottom of the drying chamber 1. A discharge hopper 14 is fixedly connected to the bottom of the drying chamber 1.

[0025] Further, ammonium perchlorate crystals are added into the feed hopper 4. These crystals are then placed inside the drying chamber 1 and positioned on the conveyor belt 12. The motor 6 is started, driving the rotating roller 11 to rotate, which in turn moves the conveyor belt 12. This movement of the conveyor belt 12 causes the ammonium perchlorate crystals above it to move. As the crystals move below the conveyor belt 12, they are pushed by the conveyor plate 13 until they are discharged from the discharge hopper 14. During this movement, the fan 17 inside the air box 3 is activated, blowing air into the drying chamber 1 to dry the crystals. The air flows from the feed hopper... The material is discharged from hopper 14 and can simultaneously dry the ammonium perchlorate crystals on both sides of the conveyor belt 12, improving the drying uniformity. The filter screen 16 prevents the ammonium perchlorate crystals from entering the air box 3. The air box 3 has an air inlet (not shown) on the right side. During the drying process, the controller 7 uses multiple heating plates 8 to heat the inside of the drying chamber 1, improving the drying efficiency. The controller 7 is equipped with electronic components such as a temperature sensor and a battery. When the temperature inside the drying chamber 1 exceeds the set threshold, the multiple heating plates 8 are turned off to prevent the ammonium perchlorate crystals from being damaged due to excessive temperature, thus achieving temperature control.

[0026] Furthermore, the uniform drying mechanism enables ammonium perchlorate crystals to achieve a more uniform drying effect inside the drying chamber 1, thereby improving drying efficiency. The controller 7 and heating plate 8 control the temperature inside the drying chamber 1, preventing excessive temperature from causing loss of ammonium perchlorate crystals. This solves the problem that existing devices are generally not good at controlling the temperature during the drying process, which can easily cause ammonium perchlorate to decompose due to heat and release harmful gases, thus affecting the quality of the raw materials.
