Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.
[0029] Example 1: A multifunctional pharmaceutical device for 7-ethylchromol, such as... Figures 1-8 As shown, it includes a fixed frame 1 and a drying cylinder 2; the two fixed frames 1 are rotatably connected to the drying cylinder 2; the rear of the drying cylinder 2 is connected to the output shaft of an external motor; the external motor drives the drying cylinder 2 to rotate.
[0030] It also includes an electric rotating rod 3, a filter screen 4, a limiting plate 5, an electric guide rail 6, an electric push rod 7, a crushing plate 8, a discharge pipe 9, a moving block 10, and a feeding assembly; the drying cylinder 2 has four drying spaces 2001; each drying space 2001 contains a filter screen 4; eight electric rotating rods 3 are rotatably connected to the outside of the drying cylinder 2; both ends of each filter screen 4 are wound around an electric rotating rod 3, and both ends of the filter screen 4 are fixedly connected to the electric rotating rod 3. An external motor drives the electric rotating rod 3 to rotate, and the electric rotating rod 3 winds up and unwinds the filter screen 4; each drying space 2001 is provided with two limiting plates 5, and each filter screen 4 passes through all the limiting plates 5 on the same drying space 2001; each drying space 2001 is fixedly connected to four electric guide rails 6. Each pair of electric guide rails 6 is located on the front and rear sides of the corresponding limiting plate 5, respectively; each electric guide rail 6 is slidably connected to a moving block 10; the two moving blocks 10 on the same side are fixedly connected to the corresponding limiting plate 5; a number of electric push rods 7 arranged in a ring array are fixedly connected to the outside of the drying cylinder 2; all the telescopic parts of the electric push rods 7 on the same side are fixedly connected to a crushing plate 8; each crushing plate 8 corresponds to a drying space 2001; a number of discharge pipes 9 are fixedly connected to the drying cylinder 2, and each discharge pipe 9 is equipped with an electrically controlled valve; the drying cylinder 2 is connected to a feeding assembly, which feeds the raw materials into the drying space 2001; a number of external heating plates are fixedly connected to the outside of the drying cylinder 2, and each external heating plate is located between an adjacent electric rotating rod 3 and an electric push rod 7.
[0031] Each drying space 2001 is equipped with two discharge troughs 2002; each discharge trough 2002 is connected to a corresponding discharge pipe 9, and the inner wall of the discharge trough 2002 is inclined to facilitate the entry of raw materials into the discharge pipe 9.
[0032] The crushing plate 8 is convex arc-shaped on the side facing the drying space 2001, which facilitates the discharge of raw materials to the discharge chute 2002.
[0033] Filter screen 4 is made of wear-resistant material, which improves the service life of filter screen 4.
[0034] It also includes protrusions 101; each limiting plate 5 is provided with a number of protrusions 101 made of hard rubber.
[0035] It also includes a placement plate 102; the two fixed frames 1 are connected to the placement plate 102 with damping sliding; the placement plate 102 is located directly below the drying cylinder 2; the height of the collection box placed on it is adjusted by the placement plate 102 to avoid a large amount of raw material being thrown up during discharge due to the large drop between the lower end of the discharge pipe 9 and the collection box.
[0036] The placement plate 102 and the fixed frame 1 are detachably connected. When a storage vehicle is needed for collection, the placement plate 102 can be removed to facilitate the collection of raw materials by the storage vehicle.
[0037] The specific work steps are as follows:
[0038] The feeding pipe of the external feeding device is connected to the feeding assembly.
[0039] When raw materials need to be dried, the external feeding device feeds the raw materials into the feeding assembly, which then sequentially discharges the raw materials into each drying chamber 2001. After the raw materials are discharged into the drying chamber 2001, the external heating plate is activated to heat the interior of the drying chamber 2001, thereby drying the raw materials. At the same time, the external motor is activated, causing the external motor to drive the drying cylinder 2 to rotate 360 degrees clockwise and counterclockwise, thus drying the raw materials. The raw materials in space 2001 are turned over to ensure even heating and prevent uneven drying caused by piling up. After the raw materials are dried, the external collection box is placed below the drying cylinder 2. Then, the external motor is controlled to drive the drying cylinder 2 to rotate, so that the drying space 2001 that needs to be discharged is directly above the collection box. Then, the electrically controlled valve in the discharge pipe 9 connected to the drying space 2001 that needs to be discharged is opened, so that the dried raw materials are discharged from the discharge pipe 9 into the external collection box, thereby completing the drying process of the raw materials.
[0040] The filter screen 4 is located between the inlet and outlet pipe 9 of the drying space 2001. When each drying space 2001 rotates to the top, the rotation of the drying cylinder 2 is paused. At this time, the electric rotating rod 3 connected to the filter screen 4 is rotated to wind up the filter screen 4. The filter screen 4 moves towards the middle of the drying cylinder 2, gathering the raw materials in the drying space 2001 towards the middle area of the drying cylinder 2. Then, the electric push rod 7 drives the crushing plate 8 to descend and approach the middle of the drying cylinder 2, so that the crushing plate 8, after moving, cooperates with the drying cylinder 2 to squeeze the large particles of raw materials gathered by the filter screen 4, thereby crushing the large particles of raw materials. Then, the crushing plate 8 moves back to its original position. When the filter screen 4 is being wound up, the electric guide rail 6 drives the moving block 10 to move the limiting plate 5 synchronously with the filter screen 4, so that the limiting plate 5 limits the filter screen 4 and is always in a state of pulling the filter screen 4. When the crushing action ends... Then, the filter screen 4 is released by rotating the electric rotating rod 3. Then, the electric guide rail 6 drives the moving block 10 to move the limiting plate 5 and pull the filter screen 4 back to its original position. When the crushing plate 8 descends, it forms an opening with the drying cylinder 2. The opening is used to discharge the moisture generated in the drying space 2001 during the drying process, so as to avoid a large amount of moisture accumulating in the drying space 2001 and affecting the drying efficiency. After the crushing plate 8 and the filter screen 4 have been reset, the external motor is controlled again to drive the drying cylinder 2 to rotate. When the next drying space 2001 rotates to the top, the above operation is repeated, so as to crush the large particles of raw materials in each drying space 2001. Thus, the filter screen 4 and the crushing plate 8 intercept and crush the large particles of raw materials during the raw material drying process, avoiding the need to screen all the dried raw materials later, thereby greatly improving production efficiency and reducing production burden.
[0041] The drying drum 2 rotates repeatedly counterclockwise and clockwise, causing all the raw materials in the drying space 2001 to tumble. Because large and small particles of raw material are mixed together during tumbling, the overall material remains in a piled-up state, which is not conducive to drying, especially for large particles. Therefore, during drying, if... Figure 3 As shown, the filter screen 4 divides the drying space 2001 into two spaces, allowing the filter screen 4 to act as a barrier and interceptor during the tumbling process of the raw materials. During tumbling, large particles of raw materials are blocked by the filter screen 4, while small particles can flow through the filter screen 4. In this state, the flowability of small particles is improved, which is conducive to the heat drying of small particles. The filter screen 4 also pre-separates large and small particles of raw materials, reducing the amount of raw materials accumulated and also facilitating the drying of large particles. Each time the drying space 2001 rotates to the top, the raw materials in the drying space 2001 are crushed by the crushing plate 8. As the drying cylinder 2 rotates, the flowability of the raw materials in the drying space 2001 becomes stronger and stronger until all large particles of raw materials are crushed. After drying is completed, all raw materials are discharged through the discharge pipe 9.
[0042] Considering that when the crushing plate 8 crushes the raw material, the crushed material will adhere to the crushing plate 8, the drying cylinder 2, and the parts of the feeding assembly used to block the drying space 2001, after the discharge of material from a single drying space 2001 is completed, the two electric rotary rods 3 are controlled to wind up the filter screen 4 until the filter screen 4 contacts the middle of the drying cylinder 2. Then, the crushing plate 8 is controlled to rise and press against the filter screen 4, so that the filter screen 4 is cleaned up by the parts of the drying cylinder 2 and the feeding assembly used to block the feed inlet of the drying space 2001. The filter screen 4 is then rolled up by one electric rotary rod 3 and unrolled by another electric rotary rod 3, so that the filter screen 4 moves in close contact with the crushing plate 8, the drying cylinder 2 and the parts of the feeding assembly used to block the feed inlet of the drying space 2001. This scrapes off the raw material particles attached to the crushing plate 8, the drying cylinder 2 and the feeding assembly, thereby preventing the raw material from adhering to the crushing plate 8, the drying cylinder 2 and the parts of the feeding assembly used to block the feed inlet of the drying space 2001 after participating in the crushing work.
[0043] During material discharge, the drying cylinder 2 will also rotate slightly counterclockwise and clockwise, driving the raw materials to move and making it easier for the raw materials to flow to the discharge pipe 9. The discharge trough 2002 will make it easier for the raw materials to be accurately discharged into the discharge pipe 9. The crushing plate 8 is arc-shaped, which makes it easier for the raw materials to flow to both sides of the crushing plate 8 to the discharge pipe 9, reducing the amount of raw materials remaining on the crushing plate 8.
[0044] Considering that some of the large particles will adhere to the filter screen 4 after being crushed, the filter screen 4 will come into contact with the protrusions 101 when it moves, so that the protrusions 101 will scrape off the particles adhering to the filter screen 4, thereby preventing the filter screen 4 from clogging. During drying, the filter screen 4 can also be unwound and wound up by controlling the two electric rotating rods 3 respectively. When one electric rotating rod 3 wound up the filter screen 4, the other electric rotating rod 3 unwound the filter screen 4, causing the filter screen 4 to move. This allows the protrusions 101 to scrape off the raw material clogging the filter screen 4, preventing clogging and improving the filtration efficiency of the raw material. During drying, the flow efficiency of the raw material can be guaranteed, thereby ensuring the drying effect.
[0045] Example 2, based on Example 1, such as Figure 2 , Figure 5 and Figure 6As shown, the feeding assembly includes a feed pipe 201, a DD motor 202, electric push rods 203, and a baffle 204; the feed pipe 201 is rotatably connected to the fixed frame 1; the feed pipe 201 is located inside the drying cylinder 2, and the feed pipe 201 has a discharge port 20101; each drying space 2001 of the drying cylinder 2 has a connecting port 2003; the discharge port 20101 is connected to the corresponding drying space 2001 through the connecting port 2003; the DD motor 202 is fixedly connected to the fixed frame 1; the rotating part of the DD motor 202 is fixedly connected to the feed pipe 201; three electric push rods 203 are fixedly connected to the upper, left, and right parts of the feed pipe 201; all the electric push rods 203 on the same side are fixedly connected to a baffle 204, which blocks the connecting port 2003 between the drying space 2001 and the feed pipe 201.
[0046] It also includes an arc plate 211; four arc plates 211 are fixedly connected to the feed pipe 201. When the feeding operation is no longer performed, the arc plates 211 can block the connection port 2003 between the drying space 2001 and the feed pipe 201 to prevent raw materials from entering the feed pipe 201.
[0047] The curved plate 211 is made of silicone. The curved plate 211 is deformed by the extrusion of the drying cylinder 2. During the rotation of the curved plate 211, the raw material attached to the curved plate 211 is scraped off through the connecting port 2003.
[0048] The specific working steps of the feeding assembly are as follows:
[0049] The feeding pipe of the external feeding device is connected to the communication and rotation.
[0050] Initially, the discharge port 20101 is located at the bottom and is connected to the bottom drying space 2001 through the connecting port 2003. At this time, the raw material is added into the drying space 2001 through the discharge port 20101 of the feed pipe 201 by an external feeding device. After the bottom drying space 2001 is filled with raw material, the drying cylinder 2 is controlled to rotate counterclockwise based on the front-to-back view, so that the next drying space 2001 is rotated to the bottom for raw material filling. The connecting port 2003 of the previous drying space 2001 that has been filled with raw material is directly opposite the baffle 204. Furthermore, the baffle 204 contacts the arc plate 211, but the baffle 204 does not contact the connecting port 2003. The baffle 204 and the arc plate 211 are in close contact to prevent the raw material from flowing out of the connecting port 2003. The baffle 204 does not interfere with the rotation of the drying cylinder 2. This process is repeated until all drying spaces 2001 are filled with raw material. The DD motor 202 drives the feed pipe 201 to rotate the arc plate 211, so that each arc plate 211 is aligned with the corresponding connecting port 2003, thus sealing all drying spaces 2001 and preventing raw material leakage during the rolling drying process.
[0051] When the drying space 2001 rotates to the top, the drying cylinder 2 stops rotating. Before the crushing plate 8 is driven to crush, the DD motor 202 is controlled to drive the feed pipe 201 to rotate, which drives the adjacent baffle 204 to rotate to the top and face the connecting port 2003. At this time, the electric push rod 203 is controlled to drive the baffle 204 to rise, so that the baffle 204 and the inner wall of the drying space 2001 are spliced into a complete arc surface, which cooperates with the crushing plate 8 to descend and crush.

Those skilled in the art can make various modifications or changes to the above embodiments without departing from the inventive concept of the present invention. Therefore, the protection scope of the present invention is not limited to the above embodiments, but should be the maximum scope that conforms to the innovative features mentioned in the claims.
