Description

Technical Field

[0001] The present invention relates to the field of acetaminophen drying, and particularly to a drying device for acetaminophen production. Background Art

[0002] Acetaminophen is an acetanilide antipyretic analgesic, also known as paracetamol, which is a white crystal or crystalline powder; odorless, slightly bitter taste, used for fever, and can also be used to relieve mild to moderate pain, such as headache, muscle pain, joint pain, neuralgia, dysmenorrhea, cancer pain, and postoperative pain, etc.

[0003] The preparation of acetaminophen is to react acetic anhydride with p-aminophenol in water, quickly complete N-acetylation while retaining the phenolic hydroxyl group, crystallize after cooling, filter, wash with water, drain, and dry to obtain crude acetaminophen. During the preparation process, acetaminophen needs to be dried. Drying can remove the moisture in solid or paste-like drugs, reduce the water content of the drugs, ensure the quality of the drugs, meet the shelf life and stability requirements. Drying can prevent the product from sticking due to excessive humidity, thus ensuring the fluidity and uniformity of the product. At the same time, the dried acetaminophen is more easily stored.

[0004] During the drying process, according to the requirements of the Chinese Pharmacopoeia, in the drying loss determination method of acetaminophen, it is mentioned that unless otherwise specified, dry to constant weight at 105°C. Therefore, the temperature of the oven should be strictly controlled at 105°C to ensure that acetaminophen will not decompose or deteriorate due to excessive temperature. During drying, the traditional method is to spread acetaminophen on the ground and dry it with hot air. Since the spread acetaminophen is not easy to turn over, the acetaminophen located above can be quickly dried, while the drying effect of the acetaminophen at the bottom is poor.

Detailed Description of the Invention

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a drying device for the production of acetaminophen.

[0037] In a typical embodiment of the present application, as Figure 1 , Figure 2 , Figure 8 and Figure 9 shown, a drying device for the production of acetaminophen includes:

[0038] A drying box body 1, in which a drying conveyor belt 2 is arranged, and acetaminophen is placed on the drying conveyor belt 2 for drying;

[0039] A feeding component 3, which is arranged on the drying box body 1 and is used to place acetaminophen on the drying conveyor belt 2. The feeding component 3 includes a storage box 4 movably installed on the drying box body 1. A plurality of feeding holes 5 are opened at the bottom of the storage box 4, a moving groove 6 is opened at the side of the storage box 4, a moving baffle 7 is movably installed on the moving groove 6, a plurality of baffle holes 8 are opened at the top of the moving baffle 7, and the plurality of baffle holes 8 are arranged in a staggered manner with the feeding holes 5. A fixed rack 9 is fixedly installed on the inner wall of the top side of the drying box body 1. A rotating disk 10 is installed on the side of the storage box 4, an external gear ring 11 is fixedly installed on the outer side of the rotating disk 10, the external gear ring 11 meshes with the fixed rack 9, a driving column 12 is fixedly installed on one side of the rotating disk 10, a driving frame 13 is fixedly installed on one side of the moving baffle 7, the driving frame 13 is movably sleeved on the driving column 12, an upper frame 14 is fixedly installed on the top of the storage box 4, and a top frame 15 is fixedly installed on the top of the drying box body 1. A telescopic cylinder 16 is arranged between the top frame 15 and the upper frame 14.

[0040] Place the storage box 4 that needs to be dried on the blanking component 3. Start the telescopic cylinder 16 to operate, drive the storage box 4 to move downward. The outer gear ring 11 outside the storage box 4 will rotate under the action of the fixed rack 9. The rotation of the outer gear ring 11 drives the rotating disk 10 to rotate, and the driving column 12 will rotate to one side position, so that the driving frame 13 moves. The movement of the driving frame 13 drives the moving baffle 7 to move. The baffle hole 8 on the moving baffle 7 changes from the initial misalignment with the blanking hole 5 to the coincidence after movement. The acetaminophen in the storage box 4 will fall into the lower drying box body 1. After moving downward for a certain time, the telescopic cylinder 16 can return to its original position. The blanking of acetaminophen can be realized by the downward movement of the storage box 4.

[0041] As a preferred implementation mode in this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, the turning component 17 is arranged in the drying box body 1 and is used to turn the acetaminophen on the drying conveyor belt 2. The turning component 17 includes a guide column 22 fixedly installed on the drying box body 1. A guide block 21 is slidably sleeved on the guide column 22. A rotating shaft 23 is rotatably installed on one side of the guide block 21. A plurality of connecting blocks 24 are fixedly installed on the rotating shaft 23. A contact roller 25 is rotatably installed on the connecting block 24. The contact roller 25 is in contact with the drying conveyor belt 2. A paving rod 26 is fixedly installed on the top of the guide block 21. The paving rod 26 is arranged in a U-shaped structure. A servo motor 18 is fixedly installed on the side of the drying box body 1. The output end of the servo motor 18 is connected with a rotating lead screw 19. The rotating lead screw 19 is located in the drying box body 1. A lead screw sliding sleeve 20 is threadedly sleeved on the rotating lead screw 19. The guide block 21 is fixedly installed on the side of the lead screw sliding sleeve 20. A rotating gear 28 is fixedly sleeved on the rotating shaft 23. An installation rack 27 is fixedly installed inside the drying box body 1. The installation rack 27 meshes with the rotating gear 28.

[0042] After blanking, the acetaminophen is located on the drying conveyor belt 2. Start the servo motor 18 on the turning component 17 to run. The servo motor 18 can achieve forward and reverse rotation. The servo motor 18 drives the rotating lead screw 19 to rotate, thereby driving the lead screw sliding sleeve 20 to move. The arranged guide block 21 and guide post 22 can limit the horizontal position of the movement of the lead screw sliding sleeve 20. Through the movement of the lead screw sliding sleeve 20, the guide block 21 can be driven to move, thereby driving the rotating shaft 23 to move back and forth. The rotating gear 28 on the rotating shaft 23 meshes with the installation rack 27. During the movement, the rotating gear 28 will rotate, and the rotating shaft 23 will also rotate while moving. After the rotating shaft 23 rotates, it drives a plurality of connecting blocks 24 to rotate. The rotating shaft 23 is located below the drying conveyor belt 2. After the connecting block 24 rotates, it will lift the drying conveyor belt 2 to form a convex shape. After the drying conveyor belt 2 is lifted, the acetaminophen located at the lifted position will become loose, the gap between them will increase, and the hot air inside can contact the acetaminophen at the bottom to achieve the drying effect. At the same time, the lifted acetaminophen will increase the moving frequency, and the acetaminophen at the highest position will slide towards both sides to achieve the turning effect of the acetaminophen. Through turning, the acetaminophen can fully contact the hot air, and the drying effect is obvious.

[0043] Furthermore, in the above solution, after the guide block 21 moves, it will drive the spreading rod 26 to move. The spreading rod 26 is arranged in a U-shaped structure. The spreading rod 26 is located on both sides of the lifted drying conveyor belt 2. The spreading rod 26 can achieve the spreading of the acetaminophen, avoiding the problem that the thickness of the acetaminophen is uneven after lifting and turning, which affects drying, and at the same time, it can also spread the acetaminophen after blanking.

[0044] In this embodiment, the drying conveyor belt 2 is selected as a Teflon conveyor belt. The Teflon conveyor belt has the best heat resistance among all conveyor belts, with a maximum heat resistance of 360 °C. The Teflon material conveyor belt of Teflon maintains a certain flexibility at different temperatures. Due to its non-sticky surface, the Teflon conveyor belt ensures that food will not adhere during the processing process. Due to the anti-pollution characteristics of the Teflon conveyor belt, it becomes an ideal choice in the pharmaceutical industry. It will not release toxic gases at normal cooking temperatures, starts to decompose at 260 °C, and will release harmful substances to the human body at 350 °C. Therefore, it is safe to use the Teflon conveyor belt in an environment of 100 °C and will not release toxic substances.

[0045] As a preferred implementation method in this embodiment, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, the heat exchange cycle component 29 is arranged inside the drying box body 1 and is used for replacing the gas inside the drying box body 1. The heat exchange cycle component 29 includes blowing holes 30 and air outlet holes 31 opened on both side walls of the drying box body 1. Hair dryers 32 are arranged inside both the blowing holes 30 and the air outlet holes 31. A blocking door plate 34 is arranged inside the blowing hole 30. A door plate groove 33 is opened on the top inner wall of the blowing hole 30. The blocking door plate 34 extends into the door plate groove 33. A return spring 35 is fixedly installed between the top of the blocking door plate 34 and the door plate groove 33. A pushing block 36 is slidably sleeved on the guiding column 22. A rotating push rod 37 is rotatably installed on one side of the pushing block 36. One end of the rotating push rod 37 is rotatably installed with a driving block 38. The driving block 38 is fixedly connected to the side part of the blocking door plate 34. A fixing plate 39 is fixedly installed on the side wall of the drying box body 1. A first conductive block 40 is fixedly installed on the side part of the fixing plate 39. A second conductive block 41 is fixedly installed on the side part of the pushing block 36. The first conductive block 40 and the second conductive block 41 are electrically connected.

[0046] With the operation of the servo motor 18, the lead screw sliding sleeve 20 is driven to move back and forth once. When the lead screw sliding sleeve 20 returns to one side position, it will push the pushing block 36 on the heat exchange cycle component 29. The movement of the pushing block 36 drives the movement of the rotating push rod 37, so that under the action of the driving block 38, the blocking door plate 34 is lifted, and the blowing hole 30 will be opened. With continuous movement, after the lead screw sliding sleeve 20 moves to the outermost edge, the blocking door plate 34 will be opened to the maximum position. At this time, the second conductive block 41 on the side of the pushing block 36 contacts the first conductive block 40, and the hair dryers 32 on both the blowing hole 30 and the air outlet hole 31 are energized and operate. The hair dryer 32 on the blowing hole 30 operates to blow the hot air in the heating box 43 into the drying box body 1. The hair dryer 32 on the air outlet hole 31 operates to blow the air in the drying box body 1 out, realizing a hot air exchange, avoiding the reduction of the temperature of the hot air in the drying box body 1, and at the same time increasing the water content in the dried air, which affects the subsequent drying of acetaminophen. Through multiple hot air exchanges, the number of times can be controlled according to the water content of acetaminophen. When the water content of acetaminophen is relatively high, the number of times can be increased. Similarly, when the water content is low, the number of times can be reduced. Fresh hot air can fully dry acetaminophen and ensure the drying effect of acetaminophen.

[0047] Further, in the above solution, as Figure 7As shown, a heating component 42 is arranged on the side of the drying box 1 for heating air. The heating component 42 includes a heating box 43 fixedly mounted on the side of the drying box 1. The heating box 43 is arranged on one side of the blowing hole 30. A heating control panel 44 is arranged on the side of the heating box 43. A heating rod 45 is arranged in the heating box 43. A plurality of n-type connecting pipes 46 are connected to the upper portion of the heating box 43. The heating rod 45 in the heating box 43 continuously heats the air to ensure that the air in the heating box 43 is at a certain temperature. The heating control panel 44 is arranged to control the heating temperature of the heating rod 45. When the heating reaches the specified temperature, the heating is stopped. The normal temperature is controlled within 100°C to avoid the influence of high temperature acetaminophen. The n-type connecting pipe 46 is arranged to facilitate the entry of external air. The n-type arrangement has the air inlet located at the lower position. Since the hot air flows upward, the heated hot air is not easy to flow out.

[0048] As a preferred implementation in this embodiment, Figure 1 , Figure 2 and Figure 10 As shown, the material collection component 47 is arranged at a lower position on one side of the drying conveyor belt 2, and is used to collect the dried acetaminophen. The material collection component 47 includes a collection box 50 arranged in the drying box 1, and the bottom of the collection box 50 extends to the bottom of the drying box 1. The collection box 50 is located at a lower position on one side of the drying conveyor belt 2. A bottom bottom inclined plate 48 is fixedly installed inside the drying box 1, and the bottom bottom inclined plate 48 is located below the drying conveyor belt 2. A scraper 49 is fixedly installed inside the drying box 1, and the scraper 49 contacts the drying conveyor belt 2.

[0049] The acetaminophen is heated by multiple hot air exchanges. After the acetaminophen is dried, the drying conveyor belt 2 can be operated. A driving motor is provided outside to drive the drying conveyor belt 2 to rotate. After the dried acetaminophen is transported to one side, it can fall into the collecting box 50 on the material collection component 47 under the action of gravity. The scraper 49 provided can scrape off the acetaminophen adhering to the drying conveyor belt 2. The bottom bottom inclined plate 48 provided can be used to collect the acetaminophen on the drying conveyor belt 2 during the turning process or the material discharging process. The acetaminophen that falls off during the turning process or the material discharging process can be collected by the bottom bottom inclined plate 48 to avoid the problem of waste.

[0050] Working principle of the present invention: When in use, after paracetamol is prepared, it is necessary to dry the paracetamol with a relatively high water content. Place the paracetamol to be dried in the storage box 4 on the feeding component 3. Start the telescopic cylinder 16 to operate and drive the storage box 4 to move downward. Under the action of the fixed rack 9, drive the rotating disk 10 to rotate, so as to drive the driving frame 13 to move and drive the movable baffle 7 to move. The baffle hole 8 on the movable baffle 7 changes from being misaligned with the feeding hole 5 at the beginning to being coincident after moving. The paracetamol in the storage box 4 will fall into the lower drying box body 1. After moving downward for a certain time, the telescopic cylinder 16 can return to its original position, and the feeding of paracetamol can be realized by the downward movement of the storage box 4;

[0051] The paracetamol after feeding is located on the drying conveyor belt 2. Start the servo motor 18 on the turning component 17 to operate and drive the lead screw slider 20 to move, thereby driving the rotating shaft 23 to move back and forth. The rotating gear 28 on the rotating shaft 23 meshes with the mounting rack 27. During the movement, the rotating gear 28 will rotate, and the rotating shaft 23 will also rotate while moving, driving a plurality of connecting blocks 24 to rotate, which will lift the drying conveyor belt 2 to form a convex shape. After the drying conveyor belt 2 is lifted, the paracetamol at the lifted position will be loosened, the gap between them will increase, and the hot air inside can contact the paracetamol at the bottom to achieve the drying effect. At the same time, the lifted paracetamol will increase the moving frequency, and the paracetamol at the highest position will slide to both sides to achieve the turning effect of the paracetamol. Through turning, the paracetamol can fully contact the hot air, and the drying effect is obvious. The spreading rods 26 are located on both sides of the lifted drying conveyor belt 2. The spreading rods 26 can spread the paracetamol, avoid the problem that the thickness of the paracetamol is uneven after lifting and turning, which affects drying, and can also spread the paracetamol after feeding;

[0052] With the operation of the servo motor 18, drive the lead screw slider 20 to move back and forth once. When the lead screw slider 20 returns to one side position, it will drive the pushing block 36 to move, thereby lifting the blocking door panel 34, and the blowing holes 30 will be opened. At the same time, the second conductive block 41 contacts the first conductive block 40, and the blowers 32 on the blowing holes 30 and the air outlet holes 31 are all powered on and operate to achieve a hot air exchange, avoid the reduction of the hot air temperature in the drying box body 1, and at the same time, the water content in the air after drying increases, which affects the subsequent drying of paracetamol. Through multiple hot air exchanges, fresh hot air can fully dry the paracetamol and ensure the drying effect of the paracetamol. By heating the paracetamol through multiple hot air exchanges, after the paracetamol is dried, the drying conveyor belt 2 can operate, and the dried paracetamol falls into the collection box 50 on the feeding and collecting component 47 to achieve collection.

[0053] It should be noted that:

[0054] In this application, the drying conveyor belt 2, servo motor 18, hair dryer 32, heating control panel 44, and heating rod 45 are all prior arts, and their specific structures, functions, and usages will not be elaborated herein.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
