Description

Technical Field

[0001] The invention relates to the technical field of medicinal material drying, and in particular to a pulverizing and drying device for pharmaceutical raw materials and a preparation method thereof. Background Art

[0002] Airflow pulverizer is a kind of equipment that uses airflow to pulverize solid materials. It can complete the pulverization process without heating or pressurizing. It is easy to operate and can effectively control the quality of drugs. In the pharmaceutical industry, airflow pulverizer is often used to prepare fine powder of drug raw materials, such as Chinese medicine powder, Western medicine powder, plant extracts, etc. Its low-temperature and medium-free pulverization characteristics can maximize the retention of active ingredients of drugs and reduce the loss of heat-sensitive drugs. At the same time, the clean and environmentally friendly pulverization process also meets the high standards of the pharmaceutical industry. In the prior art, after the material enters the air flow mill, it will enter the cage crusher together with the hot air, and then the high-speed hot air flow will blow the crushed material up and suspend it. In this process, since the air inlet is at the same position as the material feeding position, usually at the center of rotation, the crushed material is under the combined influence of gravity and air flow. The crushed material at the top of the crushing chamber can be easily suspended, while the crushed material at the bottom of the crushing chamber is easy to accumulate, resulting in waste of medicinal materials and adhesion to the inner wall of the crushing chamber, which is difficult to clean. In addition, the distance and angle between the cutting blade and the squirrel cage of the current cage crusher are usually fixed. Even if the angle can be adjusted, the outer shell needs to be opened for adjustment, which is time-consuming and labor-intensive, and difficult to adjust arbitrarily during operation. This limits its scope of application and production efficiency to a certain extent.

[0014] A method for crushing and drying a pharmaceutical raw material comprises the following steps: Step 1: Material crushing and suspension: First, the hot air in the hot air furnace and the material in the feed pipe enter the connecting pipe and are sent into the casing together. The material is crushed into mud and powder by the combined action of the cage crusher and the airflow impact. At the same time, the high-speed hot air flow blows the crushed material up and suspends it in the airflow, completing the crushing and preliminary dispersion of the material. Step 2: Airflow conveying and drying: The material suspended in the airflow is conveyed into the drying tube along with the hot airflow.

Therefore, when the sliding column slides and squeezes in the chute, the fan-shaped plate can reciprocate on its axis, and finally the push block at the bottom swings synchronously to assist in pushing up the shredded material at the bottom of the casing, which is conducive to the residual material being blown and suspended by the hot air flow, so as to fully dry and avoid waste of medicinal materials; 2. The two sides of the push block are concave inward in an I-shaped setting, which can effectively store materials when it swings, avoiding the situation where only a small amount of materials at the bottom are scraped off. The bottom of the push block is set to fit the inner wall of the machine in an arc, which reduces the friction resistance between the push block and the casing, making it easier to scrape off the materials adhering to the inner wall of the casing, which is conducive to keeping the inner wall of the casing clean, saving later cleaning time, and reducing the situation where the materials are difficult to clean by adhering to the inner wall of the crushing chamber; 3. During the working process, through the setting of the angle adjustment mechanism, the staff can adjust the angle of the cutting plate by rotating the threaded column outside through the viewing window without disassembling the casing, so as to adapt to the shredding of different material particle sizes; Among them, when the material is small, the angle between the cutting plate and the screen plate can be appropriately adjusted to be smaller to facilitate chopping the material during rotation. When the material is large, the angle between the cutting plate and the screen plate is appropriately adjusted to be larger to avoid slipping due to the failure to clamp the material. The staff can adjust the angle of the cutting plate within a certain range by changing the tension of the pull rope and the rebound force of the spring, which effectively saves the operating time of regulation and control, thereby increasing the applicability and production efficiency of the device.

[0020] The effects achieved by this embodiment are as follows: in the prior art, under the combined influence of gravity and airflow, the crushed materials at the top of the crushing chamber can be easily suspended, while the crushed materials at the bottom of the crushing chamber are easily accumulated, resulting in waste of medicinal materials and the situation that the crushed materials adhere to the inner wall of the crushing chamber and are difficult to clean.

By observing the visual window 91, the threaded column 94 is rotated externally to adjust the angle of the cutting plate 82 so as to adapt to the shredding of different material particle sizes, thereby effectively saving the operation time of the adjustment.

[0023] Embodiment 2 of the present invention A method for crushing and drying a pharmaceutical raw material comprises the following steps: Step 1: Material crushing and suspension: First, the hot air in the hot air furnace 6 and the material in the feed pipe 5 enter the connecting pipe 7, and then are sent into the casing 1 together. The material is crushed into mud and powder by the combined action of the cage crusher and the air flow impact. At the same time, the high-speed hot air flow blows the crushed material up and suspends it in the air flow, completing the crushing and preliminary dispersion of the material; Step 2: air flow conveying and drying: the material suspended in the air flow is conveyed into the drying tube 2 along with the hot air flow. During the air flow conveying process, the material is fully in contact with the hot air and is dried through heat transfer. Step 3: Separation and product collection: The dried material and airflow enter the cyclone separator 3 together. In the cyclone separator 3, due to the changes in airflow speed and direction, the material and airflow are separated. The heavier material particles are deposited at the bottom of the cyclone separator 3 and are discharged regularly through the solid flow distributor 4 as products and dry materials. Part of the dry materials can also be circulated back to the casing 1 as needed to further control the particle size and dryness of the product.

[0024] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: the push block 87 naturally hangs down at the bottom of the housing 1, the ring piece 92 is located at a side close to the housing 1, and the spring 98 is in a naturally relaxed state.

[0025] Working process: When in use, the pharmaceutical raw material enters the connecting pipe 7 from the feeding pipe 5, and the hot air flow of the hot air furnace 6 also flows into the connecting pipe 7, and then the hot air flow of the material box enters the casing 1 together, and the servo motor 81 is started by the external control system to drive the rotating shaft 84 to rotate. When the rotating shaft 84 rotates, the bracket 83 and the main gear 811 can be driven to rotate synchronously. The rotation of the bracket 83 allows the multiple cutting plates 82 to rotate along the inner wall of the sieve plate 85. The bracket 83 can stir the input material, cooperate with the cutting plate 82 to continuously chop the material, and the cutting The crushed materials pass through the sieve holes on the sieve plate 85 and enter the chamber formed by the outer wall of the sieve plate 85 and the casing 1. At the same time, the hot air flow will also assist in taking the fine crushed materials on the inner wall of the sieve plate 85 out of the sieve holes. Then the hot air flow will blow most of the crushed materials upward, making them suspended in the hot air flow, and then upward into the drying pipe 2 for drying. Some crushed materials remaining at the bottom of the casing 1 are pushed upward by the push block 87. When the main gear 811 rotates with the rotating shaft 84, the auxiliary gear 811 can be pushed upward by the main gear 811. 12 drives synchronous rotation, so that the L-shaped rod 813 also rotates, and the sliding column 814 located on the side of the L-shaped rod 813 away from the secondary gear 812 can also rotate. The sliding column 814 and the L-shaped rod 813 can form an eccentric wheel with the secondary gear 812. Therefore, when the secondary gear 812 rotates, the sliding column 814 will eventually slide continuously in the sliding groove 815. Since the axis of the sector plate 86 is consistent with the rotating shaft 84, when the sliding column 814 slides and squeezes in the sliding groove 815, the sector plate 86 can be rotated on the axis. The reciprocating swinging motion causes the push block 87 at the bottom to also do the reciprocating swinging motion. The arc-shaped hole groove 89 on the fan-shaped plate 86 can ensure the normal feeding of the connecting pipe 7, and the two sides of the push block 87 are inwardly recessed in an I-shaped arrangement, which can effectively store materials during the swinging, avoiding the situation where only a small amount of materials at the bottom are scraped off. In addition, the bottom of the push block 87 is in contact with the inner wall of the casing 1 in an arc arrangement, which reduces the friction resistance between the push block 87 and the casing 1, making it easier to scrape off the materials adhering to the inner wall of the casing 1, which is conducive to keeping the inner wall of the bottom of the casing 1 clean. Please refer to the above working process Figures 1 to 8 .

[0026] Furthermore, when the rotating shaft 84 and the bracket 83 rotate to crush the material, the movable insert ring 96 will also rotate synchronously with the bracket 83. At this time, the support rod 93 can slide in the ring groove of the movable insert ring 96 without hindering its movement. According to the size of the material, the staff can rotate the threaded column 94 to drive the ring piece 92 to move in the direction close to the servo motor 81, and the ring piece 92 drives the support rod 93 and the movable insert ring 96 to move in the same direction. When the movable insert ring 96 moves, it drives multiple pull ropes 97 to be tightened and moved synchronously. Finally, the inner side of the cutting plate 82 is pulled by the pull rope 97 to make the cutting plate 82 rotates and squeezes the spring 98, thereby changing the angle between the cutting plate 82 and the screen plate 85. The staff observes the angle through the visual window 91. When the material is small, the angle between the cutting plate 82 and the screen plate 85 can be appropriately adjusted to be small, so as to facilitate the material to be shredded during rotation. When the material is large, the angle between the cutting plate 82 and the screen plate 85 is appropriately adjusted to be large, so as to avoid the situation where the material cannot be clamped and causes slipping. Through the cooperation of the pulling force of the pull rope 97 and the rebound force of the spring 98, the angle of the cutting plate 82 can be arbitrarily adjusted within a certain range, so as to adapt to the shredding of different material particle sizes; Please refer to the above working process Figure 3 , Figures 7 to 10 .

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

10. A method for crushing and drying a pharmaceutical raw material, applied to a crushing and drying device for a pharmaceutical raw material according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: material crushing and suspension: first, the hot air in the hot air furnace (6) and the material in the feed pipe (5) enter the connecting pipe (7), and then are sent into the casing (1) together. The material is crushed into mud and powder by the combined action of the cage crusher and the air flow impact. At the same time, the high-speed hot air flow blows the crushed material up and suspends it in the air flow, completing the crushing and preliminary dispersion of the material. Step 2: air flow conveying and drying: the material suspended in the air flow is conveyed into the drying tube (2) along with the hot air flow. During the air flow conveying process, the material is fully in contact with the hot air and is dried through heat transfer. Step 3: Separation and product collection: The dried material and the airflow enter the cyclone separator (3) together. In the cyclone separator (3), due to the change in airflow speed and direction, the material and the airflow are separated. The heavier material particles are deposited at the bottom of the cyclone separator (3) and are discharged regularly through the solid flow distributor (4) as products and dry materials. Part of the dry materials can also be circulated back into the casing (1) as needed to further control the particle size and dryness of the product.
