Technical Field
[0001] This utility model relates to the field of ammonium perchlorate production technology, and in particular to a dehumidification device for ammonium perchlorate production. Background Technology
[0002] Ammonium perchlorate is an inorganic compound, mainly presenting as a white crystalline powder, and is hygroscopic. During its production, ammonium perchlorate requires dehumidification, necessitating the use of dehumidification equipment specifically designed for ammonium perchlorate production.
[0003] Existing dehumidification devices used in ammonium perchlorate production typically fail to transfer heat evenly within the device during dehumidification, resulting in poor dehumidification performance and reduced dehumidification efficiency.
[0004] Therefore, it is necessary to propose a dehumidification device for ammonium perchlorate production to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a dehumidification device for ammonium perchlorate production, in order to solve the problem that during the dehumidification process, heat cannot be evenly transferred to the dehumidification equipment, making it impossible to ensure that all areas inside the equipment are heated, resulting in poor dehumidification effect and reduced dehumidification efficiency.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a dehumidification device for ammonium perchlorate production, comprising a barrel body, wherein a dehumidification chamber is provided inside the barrel body, and a first gas supply pipe is rotatably arranged inside the dehumidification chamber. The bottom end of the first gas supply pipe is connected to a second gas supply pipe, which is funnel-shaped with a narrow top and a wide bottom. A stirring blade is fixedly connected to the outer periphery of the first gas supply pipe, and the stirring blade is spiral-shaped.
[0007] Preferably, two connecting rods are fixedly connected to the top of the first gas pipe and the bottom of the second gas pipe, and scrapers are fixedly connected to the ends of the connecting rods.
[0008] Preferably, the scraper is a triangle with one end pointed near the side wall of the dehumidification chamber, and the scraper makes movable contact with the side wall of the dehumidification chamber.
[0009] Preferably, the top surface of the barrel is provided with a second gear and a first gear, a motor is fixedly connected to the top surface of the barrel, a rotating shaft is fixedly connected to the motor shaft, the outer circumference of the rotating shaft is fixedly connected to the inner wall of the first gear, the first air supply pipe passes through the top of the barrel and is fixedly connected to the second gear, and the second gear meshes with the first gear.
[0010] Preferably, the bottom of the barrel is connected to a discharge pipe, and the top of the barrel is connected to a feed pipe and an exhaust pipe.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. In this utility model, the bucket-shaped design of the second air pipe, which is narrow at the top and wide at the bottom, can dissipate heat more widely, so that the heat is transferred more evenly into the dehumidification device, thereby improving the dehumidification efficiency.
[0013] 2. Through the cooperation of the first air supply pipe, the second air supply pipe and the stirring blade, the hot air discharged from the second air supply pipe can move upward along the rotating stirring blade, so that the hot air flows along a certain path, ensuring that all areas of the dehumidification chamber can be fully heated, which facilitates better dehumidification of ammonium perchlorate. The rotation of the stirring blade can also ensure smooth airflow and reduce the decrease in dehumidification effect caused by poor airflow.
[0014] 3. When the stirring blades rotate, they can effectively mix the ammonium perchlorate evenly, preventing it from clumping and helping the moisture in the ammonium perchlorate to be more fully exposed in the dehumidification environment, thereby improving the dehumidification efficiency.
[0015] 4. During the stirring process, the rotation of the stirring blades reduces the clogging of ammonium perchlorate inside the dehumidification device, thereby reducing equipment maintenance costs and downtime. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This invention addresses the problem that during dehumidification, heat cannot be evenly transferred within the dehumidification equipment, resulting in poor dehumidification performance and reduced efficiency due to the inability to ensure heating in all areas. It provides a solution such as… Figures 1-3 The dehumidification device for ammonium perchlorate production shown includes a barrel 1 with a dehumidification chamber 11 inside. A first air supply pipe 2 is rotatably installed inside the dehumidification chamber 11, and a second air supply pipe 21 is connected to the bottom of the first air supply pipe 2. The second air supply pipe 21 is funnel-shaped, narrower at the top and wider at the bottom. A stirring blade 22, spiral in shape, is fixedly connected to the outer periphery of the first air supply pipe 2. In use, ammonium perchlorate is added to the dehumidification chamber 11. Dry, hot air flows through the first air supply pipe 2 to the second air supply pipe 21 and enters the dehumidification chamber 11 from the second air supply pipe 21. The dry, hot air dehumidifies the ammonium perchlorate. The funnel-shaped design of the second air supply pipe 21 allows for more extensive heat dissipation, resulting in more even heat distribution within the dehumidification device and improved dehumidification efficiency. Simultaneously with the addition of hot air to the dehumidification chamber 11… The first air supply pipe 2 is rotated, which drives the stirring blade 22 to rotate. The hot air discharged from the second air supply pipe 21 can move upward along the rotating stirring blade 22, so that the hot air flows along a certain path, ensuring that all areas of the dehumidification chamber 11 can be fully heated, which facilitates better dehumidification of ammonium perchlorate. The rotation of the stirring blade 22 can also ensure smooth airflow, reducing the decrease in dehumidification effect caused by poor airflow. When the stirring blade 22 rotates, it can effectively mix the ammonium perchlorate evenly, preventing the ammonium perchlorate from clumping, and helping the moisture in the ammonium perchlorate to be more fully exposed in the dehumidification environment, thereby improving the dehumidification efficiency. During the stirring process of the stirring blade 22, the blockage of ammonium perchlorate inside the dehumidification device is reduced, reducing the maintenance cost and downtime of the equipment.
[0024] It should be noted that the top pipe of the first air supply pipe 2 is connected to the hot air blower, and the hot air blower delivers dry hot air to the dehumidification chamber 11 through the first air supply pipe 2.
[0025] In this invention, a second gear 43 and a first gear 42 are provided on the top surface of the barrel 1. A motor 4 is fixedly connected to the top surface of the barrel 1. A rotating shaft 41 is fixedly connected to the shaft of the motor 4. The outer circumference of the rotating shaft 41 is fixedly connected to the inner wall of the first gear 42. The first air supply pipe 2 passes through the top of the barrel 1 and is fixedly connected to the second gear 43. The second gear 43 meshes with the first gear 42. When in use, the motor 4 is turned on, and the motor 4 rotates, which drives the rotating shaft 41 to rotate. The rotating shaft 41 rotates, which drives the first gear 42 to rotate. The first gear 42 rotates, which drives the second gear 43 to rotate, thereby causing the first air supply pipe 2 to rotate.
[0026] In this utility model, two connecting rods 3 are fixedly connected to the top of the first gas supply pipe 2 and the bottom of the second gas supply pipe 21, and a scraper 31 is fixedly connected to the end of the connecting rod 3; the rotation of the first gas supply pipe 2 drives the connecting rod 3 to rotate, and the rotation of the connecting rod 3 drives the scraper 31 to rotate, and the scraper 31 can stir the ammonium perchlorate at the edge.
[0027] It should be noted that the scraper 31 is a triangle with one end pointed near the side wall of the dehumidification chamber 11. The scraper 31 makes active contact with the side wall of the dehumidification chamber 11. When the scraper 31 rotates, it can scrape the side wall of the dehumidification chamber 11, preventing ammonium perchlorate from sticking to the side wall of the dehumidification chamber 11, reducing unnecessary wear and tear, and avoiding waste. Preventing ammonium perchlorate from sticking to the side wall of the dehumidification chamber 11 can reduce the number of cleaning times and the difficulty of cleaning, thereby reducing maintenance costs.
[0028] In this utility model, the bottom of the barrel 1 is connected to a discharge pipe 12, and the top of the barrel 1 is connected to a feed pipe 13 and an exhaust pipe 14. Manual valves are installed on the discharge pipe 12, the feed pipe 13 and the exhaust pipe 14. The manual valves are a mature existing technology and are not shown in the figure. They will not be described in detail here. After dehumidification, ammonium perchlorate is discharged from the discharge pipe 12 and ammonium perchlorate is added into the dehumidification chamber 11 from the feed pipe 13. The hot air after use is discharged from the exhaust pipe 14.
[0029] It should be noted that the discharge pipe 12 can be connected to an air purification or waste heat recovery structure. These are existing and mature technologies, and will not be elaborated further here.
