[0032] Example 1

[0033] Combination Figures 1 to 7A vertical fluidized bed dryer for tablet production includes a support plate 3, an arc-shaped top cover 1, and a processing cylinder 6. An arc-shaped heating plate 11 is densely and fixedly connected to the inner ring of the arc-shaped top cover 1. A rotating mechanism 4 is provided on the support plate 3 and the processing cylinder 6. A cylinder cover 5 is hinged to one side of the upper and lower surfaces of the processing cylinder 6.

[0034] The auxiliary mechanism 2 includes an adjustment component 21 and a mounting component 22, with the mounting component 22 disposed outside the adjustment component 21;

[0035] The adjustment assembly 21 includes a connecting ring 215, which is fixedly connected to the left and right sides of the processing cylinder 6. An annular toothed ring 218 is fixedly connected to the outer ring of the connecting ring 215. A first annular groove 217 is opened inside the connecting ring 215 on the side away from the processing cylinder 6. Fixed seats 219 are fixedly connected to the left and right sides of the cylinder cover 5. Annular sliders 216 are slidably connected to the front and rear sides of the first annular groove 217. A connecting plate 214 is fixedly connected to the outer side of the annular slider 216. A first motor 213 is fixedly connected to the other side of the connecting plate 214. A long rod 2102 is fixedly connected to the side of the first motor 213 near the processing cylinder 6. Gears 211 are fixedly connected to the left and right sides of the long rod 2102. A connecting seat 212 is fixedly connected to the side of the connecting plate 214 near the cylinder cover 5. A hinge plate 2101 is hinged to the other side of the connecting seat 212. The other side of the hinge plate 2101 is hinged to the fixed seat 219.

[0036] There are four gears 211, which are paired up. The surface of the gears 211 meshes with the outer ring of the ring gear 218. There are two long rods 2102. The surface of the long rods 2102 is rotatably connected to the inside of the connecting plate 214. The two long rods 2102 are located on the front and rear sides of the processing cylinder 6.

[0037] Mounting assembly 22 includes a fixing plate 223, which is fixedly connected to the front and rear sides of the support plate 3. Long seats 229 are fixedly connected to the front and rear sides of the arc-shaped top cover 1, and mounting bases 226 are fixedly connected to the other side of the long seats 229. T-slots 222 are opened on the inner side of the two fixing plates 223, and T-plates 221 are fixedly connected to the outer side of the two long seats 229. The surface of the T-plates 221 and the interior of the T-slots 222 are slidably connected. A fixing rod 225 is fixedly connected to the side of the fixing plate 223 away from the support plate 3. A rotating plate 224 is rotatably connected to the surface of the fixing rod 225. A rectangular slot 228 is opened on the top of the mounting base 226. Screws 227 are threadedly connected to the interior of the mounting base 226 and the rotating plate 224. The left and right sides and the top of the rectangular slot 228 are set as openings, and the surface of the rotating plate 224 and the interior of the rectangular slot 228 are inserted.

[0038] Furthermore, the upper cover 5 rotates to open around the hinge with the processing cylinder 6, and the lower cover 5 rotates to close around the hinge with the processing cylinder 6. After the tablets are placed into the feed port of the processing cylinder 6, the first motor 213 corresponding to the upper cover 5 is controlled to rotate, so that the upper cover 5 closes, thereby covering the feed port of the processing cylinder 6 and preventing the tablets from falling out of the feed port during the drying process. The arc-shaped top cover 1 covers the top of the processing cylinder 6, and the arc-shaped heating plate 11 is connected to an external power source through a preset wire. After being powered on, it can generate heat and provide a heat source for the drying process.

[0039] Example 2

[0040] See Figure 1-8 Furthermore, based on Embodiment 1, the rotating mechanism 4 further includes a second motor 41, which is fixedly connected to the left side of the left support plate 3. A rotating shaft 45 is fixedly connected to the right side of the second motor 41. The rotating shaft 45 is fixedly connected to the left side of the processing cylinder 6. A rotating rod 43 is fixedly connected to the right side of the processing cylinder 6. The surface of the rotating rod 43 is rotatably connected to the inside of the right support plate 3. Annular sliding plates 42 are fixedly connected to the left and right sides of the processing cylinder 6. A second annular groove 44 is opened on the inner side of the two support plates 3. The four annular sliding plates 42 are grouped together. A connecting ring 215 is set on the outer side of the four annular sliding plates 42. The surface of the annular sliding plates 42 is slidably connected to the inside of the second annular groove 44.

[0041] Furthermore, the second motor 41 drives the rotating shaft 45 to rotate, and the rotating shaft 45 drives the processing cylinder 6 and the rotating rod 43 on the right side to rotate synchronously. The annular slide plate 42 slides along the second annular slide groove 44 to ensure the stable rotation of the processing cylinder 6. At the same time, the arc-shaped heating plate 11 is energized and heats up. The heat enters the interior of the processing cylinder 6 through the densely opened holes on the surface of the processing cylinder 6 and the cylinder cover 5, and fully contacts the tablets inside the rotating processing cylinder 6 to achieve uniform drying of the tablets. The water vapor generated during drying is discharged through the holes.

[0042] In actual operation, when this device is used, the T-shaped plate 221 is aligned with the T-shaped groove 222, and the arc-shaped top cover 1 is slid along the T-shaped groove 222 to cover the top of the processing cylinder 6. The rotating plate 224 on the surface of the fixing rod 225 is rotated to insert it into the rectangular groove 228. Then, the screw 227 passes through the rotating plate 224 and the mounting base 226 and is tightened to complete the fixing of the arc-shaped top cover 1. The arc-shaped heating plate 11 is connected to an external power source through a preset wire. After being powered on, it can generate heat to provide a heat source for the drying process.

[0043] Two first motors 213 are controlled to rotate in opposite directions, one forward and one reverse. The first motors 213 drive the long rod 2102 and the gear 211 on the surface to rotate. The gear 211 meshes with the annular toothed ring 218, causing the annular slider 216 to slide along the first annular groove 217, which in turn drives the connecting plate 214 to rotate. The connecting seat 212 on one side of the connecting plate 214 pulls the fixed seats 219 on the left and right sides of the cylinder cover 5 through the hinge plate 2101, so that the upper cylinder cover 5 rotates to open with the hinge of the processing cylinder 6 as the axis, and the lower cylinder cover 5 rotates to close with the hinge of the processing cylinder 6 as the axis. After the tablets are put into the feed port of the processing cylinder 6, the first motor 213 corresponding to the upper cylinder cover 5 is controlled to rotate, so that the upper cylinder cover 5 is closed, thereby covering the feed port of the processing cylinder 6 and preventing the tablets from falling out of the feed port during the drying process.

[0044] The second motor 41 is started, which drives the rotating shaft 45 to rotate. The rotating shaft 45 drives the processing cylinder 6 and the rotating rod 43 on the right side to rotate synchronously. The annular slide plate 42 slides along the second annular slide groove 44 to ensure the stable rotation of the processing cylinder 6. At the same time, the arc-shaped heating plate 11 is powered on and heats up. The heat enters the processing cylinder 6 through the densely opened holes on the surface of the processing cylinder 6 and the cylinder cover 5, and fully contacts the tablets in the rotating processing cylinder 6 to achieve uniform drying of the tablets. The water vapor generated during drying is discharged through the holes.

[0045] After the tablets are dried, the first motor 213 corresponding to the lower cover 5 is started. At this time, there is no need to adjust the orientation of the feed inlet of the processing cylinder 6. When the lower cover 5 is opened, the dried tablets can fall directly from the opened feed inlet automatically, which is convenient for collection.

[0046] When the arc-shaped top cover 1 needs regular maintenance, unscrew the screw 227, rotate the rotating plate 224 to disengage it from the rectangular groove 228, slide the T-shaped plate 221 out along the T-shaped groove 222, and the arc-shaped top cover 1 can be removed from the support plate 3. Clean or repair the arc-shaped heating plate 11 and the inner ring of the arc-shaped top cover 1. After maintenance, reset it according to the installation steps.

[0047] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
