[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model solves the problem that the electromagnetic roller cannot be cleaned immediately, the excessive accumulation of impurities will affect the continuity and efficiency of iron removal, and the failure to remove impurities in time will cause the surface of the electromagnetic roller to wear, reducing the service life of the electromagnetic roller. Figure 1-Figure 3 The shown device is an ammonium perchlorate production raw material iron removal device, including a shell 1, wherein electromagnetic rollers 2 are rotatably provided at the top and bottom of the inner wall of the shell 1, the two electromagnetic rollers 2 are staggered, and a scraper 21 is provided at the bottom of the electromagnetic roller 2. The two ends of the scraper 21 are fixedly connected to the inner wall of the shell 1, and the top of the scraper 21 movably contacts the outer periphery of the electromagnetic roller 2. The bottoms of the two electromagnetic rollers 2 are respectively provided with a first blanking plate 22 and a second blanking plate 23, which are inclined. There is a gap between the top surface of the first blanking plate 22 and the second blanking plate 23 and the bottom of the corresponding scraper 21.

[0024] Ammonium perchlorate (NH4ClO4) is an inorganic compound whose preparation typically involves the use of high-purity HClO4 (perchloric acid) as a raw material. Through a chemical reaction, HClO4 reacts with ammonia (NH3) to produce NH4ClO4. This preparation method has the advantages of high product purity, fewer refining steps, and low production costs. However, if the preparation process is not properly controlled and purified, iron impurities may be introduced. The generation of iron impurities may be related to the preparation equipment, the purity of the raw materials, and the reaction conditions. For example, if the reaction equipment contains iron elements, or there are iron impurities in the raw materials, these impurities may be incorporated into the final product during the reaction, resulting in iron impurities in the ammonium perchlorate.

[0025] When ammonium perchlorate is deironed, the preliminarily prepared ammonium perchlorate raw material is added to the shell 1 from the top. The electromagnetic roller 2 is usually composed of a rotating metal roller and an electromagnetic field system. It is a mature technology in the existing technology and will not be repeated again. The electromagnetic field system is energized. When the electromagnetic system is energized, magnetic force is generated on the periphery of the electromagnetic roller 2. At this time, the electromagnetic roller 2 is rotated. During the rotation of the electromagnetic roller 2, the iron impurities in the ammonium perchlorate are adsorbed. The lower electromagnetic roller 2 is arranged on one side of the rotation direction of the upper electromagnetic roller 2. The upper electromagnetic roller 2 rotates the ammonium perchlorate downward, and the lower electromagnetic roller 2 further deirons the ammonium perchlorate. By setting the upper and lower electromagnetic rollers 2, the iron impurities in the ammonium perchlorate can be better adsorbed. After the iron impurities on the electromagnetic roller 2 rotate to the position of the scraper 21, Blocked by it, when new ammonium perchlorate is added, the electromagnetic field system in the electromagnetic drum 2 is turned off, and the iron impurities at the scraper 21 position fall onto the corresponding second unloading plate 23 or the first unloading plate 22, and the iron impurities slide out of the shell 1 along the second unloading plate 23 or the first unloading plate 22, making it convenient for the staff to collect the impurities. Through the setting of the scraper 21, the iron impurities on the electromagnetic drum 2 can be removed while the electromagnetic drum 2 is rotating, avoiding excessive accumulation of impurities, thereby ensuring the continuity and efficiency of the iron removal process, and the scraper 21 can remove the iron impurities on the electromagnetic drum 2 in time, reducing the wear on the surface of the electromagnetic drum 2, thereby extending the service life of the electromagnetic drum 2, and effectively removing impurities, avoiding damage and replacement frequency of the electromagnetic drum 2 due to impurity accumulation, thereby reducing maintenance costs.

[0026] It should be noted that the electromagnetic roller 2 rotates toward the third blanking plate 24 .

[0027] Furthermore, since there is a gap between the first blanking plate 22 and the second blanking plate 23 and the corresponding scraper 21 , the scraped iron impurities can smoothly slide out of the housing 1 from the first blanking plate 22 and the second blanking plate 23 .

[0028] Furthermore, based on the fact that the outer surface of the electromagnetic drum 2 is a cylindrical structure and the electromagnetic drum 2 is placed horizontally, when the raw material falls on the upper surface of the electromagnetic drum 2, the raw material slides downward from the upper end of the electromagnetic drum 2 by its own gravity, and during the sliding process, the raw material slides along the outer curved surface of the electromagnetic drum 2, so that the raw material can form a thin fluid layer on the outer surface of the electromagnetic drum 2, and the iron impurities in the raw material can be fully absorbed, replacing the existing technology of using stirring and other technologies to remove iron, in which the raw material cannot fully contact with the magnet, thereby improving the iron removal effect during the raw material removal process.

[0029] In the present invention, a rotating shaft 31 is rotatably provided at the top and bottom of the inner wall of the shell 1, and the outer periphery of the rotating shaft 31 is fixedly connected to the inner wall of the electromagnetic drum 2. A motor 3 is fixedly provided on one side of the outer wall of the shell 1, and the rotating shaft of the motor 3 is fixedly connected to the end of the rotating shaft 31 located at the bottom; when the motor 3 is turned on, the motor 3 rotates to drive the rotating shaft 31 below to rotate, and the rotating shaft 31 below rotates to drive the electromagnetic drum 2 at the bottom to rotate. When the rotating shaft 31 below and the electromagnetic drum 2 rotate, the rotating shaft 31 above and the electromagnetic drum 2 rotate synchronously.

[0030] It should be noted that a transmission belt 33 and two transmission wheels 32 are provided on one side of the outer wall of the shell 1, the end of the rotating shaft 31 is fixedly connected to the transmission wheel 32, and the transmission wheel 32 is connected to the transmission belt 33; the rotation of the lower rotating shaft 31 drives the lower transmission wheel 32 to rotate, and the lower transmission wheel 32 drives the upper transmission wheel 32 to rotate through the transmission belt 33, thereby rotating the upper rotating shaft 31 and the electromagnetic drum 2.

[0031] In the present utility model, the ends of the first blanking plate 22 and the second blanking plate 23 are fixedly connected to the third blanking plate 24 and the fourth blanking plate 25 respectively. The third blanking plate 24 and the fourth blanking plate 25 are inclined, and the end of the fourth blanking plate 25 is in active contact with the outer periphery of the electromagnetic roller 2 located at the bottom. The first blanking plate 22, the second blanking plate 23, the third blanking plate 24 and the fourth blanking plate 25 are fixedly connected to the inner wall of the shell 1 on both sides; after the upper electromagnetic roller 2 completes the deironing of ammonium perchlorate, the ammonium perchlorate falls into the fourth blanking plate 25 along the upper electromagnetic roller 2, and slides along the fourth blanking plate 25 to the lower electromagnetic roller 2. The lower electromagnetic roller 2 further deirons the ammonium perchlorate. After the deironing is completed, the ammonium perchlorate falls into the third blanking plate 24 and slides out along the third blanking plate 24. The staff collects the deironed ammonium perchlorate and completes the work.

[0032] It should be noted that a baffle plate 26 is fixedly connected to the top surface of the inner wall of the shell 1, and the bottom end of the baffle plate 26 is in active contact with the electromagnetic roller 2 located at the top, and the baffle plate 26 is located on the side close to the second unloading plate 23; the baffle plate 26 prevents ammonium perchlorate from sliding from the other side of the electromagnetic roller 2 above, thereby preventing ammonium perchlorate without iron removal from falling into the impurities.

[0033] In the utility model, the top surface of the shell 1 is connected to the feed pipe 13, the top and bottom of one side of the shell 1 are both provided with a second discharge port 12, the bottom of the other side of the shell 1 is provided with a first discharge port 11, the third blanking plate 24 passes through the first discharge port 11, and the first blanking plate 22 and the second blanking plate 23 respectively pass through the corresponding second discharge port 12; ammonium perchlorate is added to the shell 1 from the feed pipe 13, and after the ammonium perchlorate is deironed, the iron impurities slide from the scraper 21 or the first blanking plate 22 to the second discharge port 12, and the ammonium perchlorate slides from the third blanking plate 24 to the first discharge port 11.

[0034] It should be noted that the staff can place storage boxes for collecting waste and ammonium perchlorate at the second discharge port 12 and the first discharge port 11 respectively. The storage box is a mature technology in the existing technology and is not shown in the figure and will not be described here.
