Description

Technical Field

[0001] This invention relates to the field of pulverizing equipment technology, specifically a non-stick-wall pulverizing device suitable for viscous traditional Chinese medicine. Background Technology

[0002] In the field of traditional Chinese medicine (TCM) processing, viscous TCM herbs (such as donkey-hide gelatin, prepared rehmannia root, and processed polygonatum) contain polysaccharides and colloids, requiring pulverization to improve the efficiency and effectiveness of subsequent extraction and preparation processes. Pulverization equipment is a key piece of equipment for this processing step. Currently, most commonly used TCM pulverization devices in the industry have a general-purpose structure, mainly consisting of a pulverization chamber, pulverization components (such as blades and hammers) within the pulverization chamber, and a drive component. Their design focuses more on pulverizing ordinary non-viscous or low-viscous TCM herbs, without being specifically optimized for the special physical properties of viscous TCM herbs. Therefore, they are difficult to adapt to the pulverization requirements of viscous TCM herbs in actual processing. When processing viscous traditional Chinese medicines, existing pulverizing devices commonly suffer from the technical problem of medicines easily adhering to the inner wall of the pulverizing chamber. During the pulverizing process, the frictional heat generated by the mechanical force of viscous medicines further enhances their viscosity. The pulverized powder or particles easily adhere to the inner wall of the pulverizing chamber, leading not only to a reduction in the actual pulverized volume and a significant decrease in pulverizing efficiency, but also to a waste of raw materials. Furthermore, if the medicines adhering to the chamber wall are not cleaned in time, they will gradually accumulate and dry over time, affecting the purity of subsequent batches of pulverized medicines, increasing the difficulty of equipment cleaning, and potentially even hindering the operation of the pulverizing components due to the dried material, thus shortening the equipment's lifespan and causing numerous inconveniences for the large-scale, standardized processing of viscous traditional Chinese medicines.

[0003] Therefore, it is necessary to provide a non-stick wall-mounted pulverizing device suitable for viscous traditional Chinese medicine to solve the above-mentioned technical problems. Summary of the Invention

[0008] A further feature of the present invention is that the inner cavity of the crushing cylinder is provided with multiple partitions, the partitions divide the inner cavity of the crushing cylinder into multiple crushing zones, a gap is provided between the top wall of the partition and the top inner wall of the crushing cylinder so that the tops of the multiple crushing zones are connected, and the rotating shaft passes through the multiple partitions and is rotatably engaged with the partitions.

[0009] A further feature of the present invention is that: multiple crushing mechanisms are provided, the multiple crushing mechanisms are separated by multiple partitions, and each of the multiple crushing zones is provided with a connecting rod and a scraper.

[0010] A further configuration of the present invention is as follows: the crushing mechanism includes a second rotating shaft and a plurality of crushing blades; the partition is a hollow structure; the end of the second rotating shaft extends into the inner cavity of the partition and is rotatably connected to the partition; a plurality of crushing blades are fixedly mounted on the second rotating shaft; a first gear and a second gear are provided inside the partition; the first gear is fixedly mounted on the first rotating shaft and the second gear is fixedly mounted on the second rotating shaft; the first gear and the second gear mesh; and the diameter of the first gear is larger than the diameter of the second gear.

[0011] A further feature of the present invention is that the feeding channel is an L-shaped mechanism, and a valve assembly is provided inside the feeding channel. The valve assembly includes a valve disc, a connecting shaft, and a second motor. The valve disc is rotatably mounted inside the feeding channel via the connecting shaft. A second mounting cavity is provided inside the mounting base. The second motor is fixedly mounted inside the second mounting cavity, and the output end of the second motor is fixedly connected to the end of the connecting shaft.

[0012] A further feature of the present invention is that an air inlet pipe is fixedly connected to the side of the valve disc away from the connecting shaft.

[0015] In summary, the present invention has the following beneficial effects: This invention effectively solves the technical problem of traditional Chinese medicine (TCM) easily sticking to the inner wall of the pulverizing chamber when processing viscous TCM in existing pulverizing devices. When the motor drives the rotating shaft to rotate, the rotating shaft can drive the pulverizing mechanism through transmission to pulverize the viscous TCM that enters the inner cavity of the pulverizing cylinder through the feeding hopper and feeding channel, ensuring the basic pulverizing processing needs. In addition, the rotating shaft drives the connecting rod and scraper to rotate synchronously. Since the scraper is in close contact with the inner peripheral wall of the pulverizing cylinder and is set parallel to the rotating shaft, the scraper can scrape off the viscous TCM adhering to the inner peripheral wall of the pulverizing cylinder in real time during the rotation process, avoiding the accumulation of viscous TCM on the cylinder wall. This design not only prevents the problem of reduced actual pulverization volume and decreased pulverization efficiency caused by TCM sticking, reducing the waste of TCM raw materials, but also avoids the risks of long-term accumulation and drying of sticky TCM affecting the purity of subsequent batches of TCM, increasing the difficulty of equipment cleaning, hindering the operation of pulverizing components, and shortening the service life of equipment. It provides reliable structural support for the stable processing of viscous TCM. This invention, through the design of a fan, filter holes, mounting cavity one, air conveying channel, diversion cavity, and air outlet, achieves directional conveying and separation of pulverized Chinese herbal medicine powder. It effectively solves the problems of easy accumulation and incomplete separation of viscous Chinese herbal medicine powder after pulverization in existing devices. Outside air enters mounting cavity one after being filtered through the filter holes. Under the action of the fan, it enters the diversion cavity through the air conveying channel and air inlet, and finally is blown into the inner cavity of the pulverizing cylinder through the air outlet. This airflow interacts with the Chinese herbal medicine powder lifted by the rotating scraper one. The airflow can carry qualified powder towards the discharge hopper, while larger particles that do not meet the standards cannot be carried away by the airflow due to gravity and remain in the pulverizing area for further pulverization. This design improves powder separation efficiency and ensures uniform particle size of the pulverized products, avoiding the unstable pulverization quality caused by particle mixing in traditional devices. Through the multi-pulverization zone design formed by multiple baffles, combined with independently set pulverization mechanisms and scrapers in each pulverization zone, a stepped pulverization and cleaning system is constructed, solving the technical defects of existing devices in not thoroughly processing insufficiently pulverized particles. The gap design between the top wall of the baffle and the inner wall of the top of the pulverizing cylinder allows airflow to carry particles to flow in each pulverization zone, and through the relay pulverization of multiple sets of pulverizing mechanisms, it ensures that a few substandard particles moving with the airflow can continue to be processed in subsequent pulverization zones.

[0018] The present invention will be further described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Please see Figures 1-10 In this embodiment of the invention, a non-sticking wall-type pulverizing device suitable for viscous traditional Chinese medicine includes a base 1, a pulverizing cylinder 2 fixedly installed above the base 1, a mounting base 3 fixedly installed at the end of the pulverizing cylinder 2, and a feeding hopper 4 fixedly installed at the top of the mounting base 3. The mounting base 3 has a feeding channel 302 inside, and the feeding hopper 4 communicates with the inner cavity of the pulverizing cylinder 2 through the feeding channel 302. A rotating shaft 6 is rotatably mounted inside the pulverizing cylinder 2, and a connecting rod 7 is fixedly installed on the rotating shaft 6. A scraper 8 is fixedly installed at the end of the connecting rod 7 away from the rotating shaft 6. The scraper 8 is in contact with the inner peripheral wall of the pulverizing cylinder 2, and the scraper 8 and the rotating shaft 6 are arranged parallel to each other. A device for... A motor 5 drives the rotating shaft 6 to rotate, and the output end of the motor 5 is fixedly connected to the end of the rotating shaft 6. The inner cavity of the pulverizing cylinder 2 is equipped with a pulverizing mechanism, which is connected to the rotating shaft 6 for transmission. In specific use, the viscous Chinese medicine is put into the feeding hopper 4 and enters the inner cavity of the pulverizing cylinder 2 through the feeding channel 302. Then, it is pulverized by the pulverizing mechanism in the inner cavity of the pulverizing cylinder 2. The operation of the pulverizing mechanism is driven by the rotation of the rotating shaft 6. When the rotating shaft 6 rotates, it drives the connecting rod 7 to rotate, thereby driving the scraper 8 to rotate. The scraper 8 is in contact with the inner peripheral wall of the pulverizing cylinder 2, so that when the scraper 8 rotates, it can scrape off the viscous Chinese medicine adhering to the inner peripheral wall of the pulverizing cylinder 2, thereby preventing the viscous Chinese medicine from sticking to the inner peripheral wall of the pulverizing cylinder 2.

[0020] In this embodiment, preferably, a discharge hopper 17 is fixedly installed at the bottom of the end of the pulverizing cylinder 2 away from the mounting base 3, and the discharge hopper 17 is connected to the inner cavity of the pulverizing cylinder 2; the pulverized Chinese medicine powder is discharged through the discharge hopper 17 and is collected by a receiving device set at the outlet of the discharge hopper 17.

[0021] In this embodiment, preferably, the top of the inner wall of the crushing cylinder 2 near the mounting base 3 has multiple air outlets 203. The mounting base 3 has a mounting cavity 305 inside, and a fan 14 is installed inside the mounting cavity 305. The mounting cavity 305 is connected to the air outlets 203. Multiple filter holes 301 are provided on the side of the mounting base 3 away from the crushing cylinder 2, and all filter holes 301 are connected to the mounting cavity 305. Specifically, a diversion cavity 202 is provided inside the side wall of the crushing cylinder 2 near the mounting base 3. Multiple air inlets 204 are connected to the side of the diversion cavity 202 away from the air outlets 203. The air outlets 203 are connected to the diversion cavity 202. The interior of the mounting base 3... Multiple air conveying channels 303 are provided, one end of each air conveying channel 303 is connected to multiple air inlets 204, and the other end of each air conveying channel 303 is connected to the mounting cavity 305. After pulverizing for a period of time, the blower 14 is turned on, and outside air enters the mounting cavity 305 after being filtered through the filter hole 301. The blower 14 conveys air into the diversion cavity 202 through the air conveying channels 303 and the air inlets 204, and then outputs it through the air outlet 203. During the pulverization process, the rotating shaft 6 drives the scraper 8 to rotate through the connecting rod 7, causing the pulverized Chinese medicine powder to be lifted up and move towards the discharge hopper 17 under the action of the airflow. Larger particles of Chinese medicine cannot be carried away by the airflow and continue to fall and be pulverized by the pulverizing mechanism.

[0022] In this embodiment, preferably, the inner cavity of the grinding cylinder 2 is provided with multiple partitions 9, which divide the inner cavity of the grinding cylinder 2 into multiple grinding zones. A gap is provided between the top wall of the partition 9 and the top inner wall of the grinding cylinder 2, allowing the tops of the multiple grinding zones to be connected. The rotating shaft 6 passes through the multiple partitions 9 and is rotatably engaged with the partitions 9. Multiple grinding mechanisms are provided, separated by multiple partitions 9. Each grinding zone is provided with a connecting rod 7 and a scraper 8. A few larger medicinal particles may, under the action of airflow, cross the partitions 9 and move towards the motor 5. In some cases, the herbal granules are not completely pulverized. By setting up multiple pulverizing zones, these granules can continue to be pulverized in the next pulverizing zone, ensuring pulverization quality. The arrangement of the fan 14, filter 301, mounting cavity 305, air conveying channel 303, diversion cavity 202, and air outlet 203 enables directional conveying and separation of the pulverized herbal powder. This effectively solves the problems of easy accumulation and incomplete separation of viscous herbal powder after pulverization in existing devices. Outside air enters the mounting cavity 305 after being filtered through the filter 301, and is then conveyed by the fan 14. The airflow enters the distribution chamber 202 through the air duct 303 and the air inlet 204, and is finally blown into the inner cavity of the pulverizing cylinder 2 through the air outlet 203. This airflow interacts with the medicinal powder lifted by the rotating scraper 8, causing the qualified powder to move towards the discharge hopper 17. Larger particles that do not meet the standards cannot be carried away by the airflow due to gravity and remain in the pulverizing zone for further pulverization. This improves powder separation efficiency and ensures the uniformity of the pulverized product's particle size, avoiding the unstable pulverization quality problem caused by particle mixing in traditional devices. The multi-pulverizing zone design formed by multiple partitions 9, combined with independently installed pulverizers in each zone, further enhances the pulverizing efficiency. The structure, along with scraper 8, creates a stepped crushing and cleaning system, solving the technical defect of existing devices that do not thoroughly process insufficiently crushed particles. The gap design between the top wall of the baffle 9 and the top inner wall of the crushing cylinder 2 allows airflow to carry particles through each crushing zone, and the relay crushing by multiple crushing mechanisms ensures that a few substandard particles moving with the airflow can continue to be processed in subsequent crushing zones. At the same time, each crushing zone is equipped with scraper 8, which can specifically clean the sticky Chinese medicine adhering to the inner wall of the corresponding zone, significantly improving the overall crushing efficiency and raw material utilization rate, and providing structural guarantee for the fine processing of sticky Chinese medicine.

[0023] In this embodiment, preferably, the pulverizing mechanism includes a second rotating shaft 12 and multiple pulverizing blades 13. The partition 9 is a hollow structure. The end of the second rotating shaft 12 extends into the inner cavity of the partition 9, and the second rotating shaft 12 is rotatably connected to the partition 9. Multiple pulverizing blades 13 are fixedly installed on the second rotating shaft 12. A first gear 10 and a second gear 11 are provided inside the partition 9. The first gear 10 is fixedly mounted on the first rotating shaft 6, and the second gear 11 is fixedly mounted on the second rotating shaft 12. The first gear 10 and the second gear 11 mesh with each other. The diameter of the first gear 10 is larger than the diameter of the second gear 11, so that the rotational speed of the second gear 11 is greater than that of the first gear 10. When the first rotating shaft 6 rotates, the first rotating shaft 6 drives the second gear 11 to rotate through the first gear 10, thereby driving the second rotating shaft 12 to rotate, and then driving the multiple pulverizing blades 13 to rotate, so that the pulverizing blades 13 pulverize the Chinese medicine entering the pulverizing zone.

[0024] In this embodiment, preferably, the feeding channel 302 is an L-shaped mechanism. A valve assembly is provided inside the feeding channel 302. The valve assembly includes a valve disc 18, a connecting shaft 19, and a second motor 23. The valve disc 18 is rotatably mounted inside the feeding channel 302 via the connecting shaft 19. The mounting base 3 has a second mounting cavity 304 inside. The second motor 23 is fixedly mounted inside the second mounting cavity 304. The output end of the second motor 23 is fixedly connected to the end of the connecting shaft 19. The second motor 23 is a servo motor. The rotation angle of the valve disc 18 is 0-90°. The second motor 23 can drive the valve disc 18 to rotate. When the valve disc 18 is in a horizontal state, the feeding channel 302 is in a closed state. At this time, the Chinese medicine in the feeding hopper 4 cannot enter the crushing cylinder 2 through the feeding channel 302. When the valve disc 18 is in a vertical state, the feeding channel 302 is in an open state. At this time, the Chinese medicine in the feeding hopper 4 can enter the crushing cylinder 2 through the feeding channel 302.

[0025] In this embodiment, preferably, an air inlet pipe 20 is fixedly connected to the side of the valve disc 18 away from the connecting shaft 19. The air inlet pipe 20 is coaxially arranged with the connecting shaft 19. The air inlet pipe 20 and the inner side of the valve disc 18 are jointly provided with a blower channel 21. The end of the blower channel 21 away from the blower 14 is located in the middle of the valve disc 18. One end of the blower channel 21 is connected to the mounting cavity 305. The other end of the blower channel 21 is equipped with a one-way valve plate 22. When the device is performing the pulverizing operation, the valve disc 18 is in a horizontal state. As the blower 14 is turned on, part of the airflow enters the blower channel 21 and pushes open the one-way valve plate 22 to blow it out, so that part of the airflow enters the feeding channel 302. Under the action of the airflow, the Chinese medicine in the feeding channel 302 is blown into the pulverizing cylinder 2 to prevent the Chinese medicine from remaining in the feeding channel 302.

[0026] In this embodiment, preferably, the end of the rotating shaft 6 away from the motor 5 extends into the feeding channel 302, and a connecting rod 15 is fixedly installed at the end of the rotating shaft 6 away from the motor 5. A scraper 16 is fixedly installed at the end of the connecting rod 15 away from the rotating shaft 6. The scraper 16 and the connecting shaft 19 are arranged parallel to each other, and the scraper 16 is in contact with the inner wall of the feeding channel 302. When the rotating shaft 6 rotates, it can drive the scraper 16 to rotate through the connecting rod 15. When the scraper 16 rotates, it cleans the inner wall of the horizontal part of the feeding channel 302 to scrape off the Chinese medicine adhering to the inner wall of the feeding channel 302 and blow it into the interior of the pulverizing cylinder 2 under the action of airflow.

[0027] In this embodiment, preferably, a controller 24 is provided on one side of the base 1. The controller 24 is used to control the operation of the crushing device. The controller 24 is electrically connected to the motor 5, motor 23, and fan 14 in the device. It can achieve precise coordinated control of each component through preset programs or manual operation commands. The specific control logic is as follows: When the crushing operation is started, the controller 24 first sends a signal to the motor 23, driving it to rotate the connecting shaft 19, so that the valve disc 18 rotates from the horizontal closed state to the vertical open state, opening the feeding channel 302; after the feeding is completed or according to the feeding requirements, the controller 24 can adjust the motor 23 to reverse, control the valve disc 18 to rotate to a suitable angle to adjust the feeding rate, or completely close the channel to stop the feeding. Simultaneously, the controller 24 sends a start signal to the motor 5, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the rotating shaft 12 and the pulverizing blade 13 in each pulverizing zone to rotate at high speed through gear transmission, realizing the pulverization of traditional Chinese medicine. On the other hand, it drives the scraper 8 and scraper 16 to rotate synchronously, respectively cleaning the material adhering to the inner wall of the pulverizing cylinder 2 and the inner wall of the feeding channel 302. During the pulverization process, the controller 24 can automatically send a start signal to the fan 14 according to the preset time or pulverization conditions, controlling the fan 14 to operate, so that the outside air enters the mounting cavity 305 after being filtered through the filter hole 301, and then enters the air supply cavity 305 through the air delivery system. Channel 303 and diversion chamber 202 blow air into the crushing cylinder 2 through the air outlet 203, assisting the powder to move towards the discharge hopper 17. At the same time, part of the airflow is blown into the feeding channel 302 through the blower channel 21 to prevent material residue. If it is necessary to stop the operation, the controller 24 first controls the motor 23 to close the feeding channel 302, and then delays the control of the motor 5 and the blower 14 to stop, ensuring that the residual material in the cylinder is fully crushed and discharged. The entire process can be automated and intelligently controlled by setting parameters (such as motor speed, blower 14 start and stop time, valve disc 18 opening degree) and monitoring the operating status through the operation interface of the controller 24.

[0028] In this embodiment, preferably, the crushing cylinder 2 is provided with a cover plate 201, which is rotatably connected to the crushing cylinder 2 and can be locked. When the cover plate 201 is opened, the crushing zone inside the crushing cylinder 2 is opened, so that the crushing mechanism, scraper 8 and other structures in the crushing zone can be cleaned after crushing is completed.

[0029] Working principle: Before pulverization, motor 23 drives connecting shaft 19 to rotate valve disc 18, opening feeding channel 302 and making valve disc 18 vertical. The viscous Chinese medicine is then fed into feeding hopper 4 and enters the inner cavity of pulverizing cylinder 2 through feeding channel 302. Subsequently, motor 5 starts, driving rotating shaft 6 to rotate. On one hand, rotating shaft 6, through gear 10 and gear 2 11, drives multiple rotating shafts 2 12 and pulverizing blades 13 to rotate at high speed, using multiple sets of pulverizing blades 13 to perform step-by-step pulverization of the Chinese medicine in different pulverizing zones. On the other hand, rotating shaft 6 simultaneously drives connecting rod 7 and scraper 8 of each pulverizing zone to rotate. Scraper 8 is in contact with the inner wall of pulverizing cylinder 2, which can scrape off the viscous Chinese medicine adhering to the cylinder wall in real time, preventing the Chinese medicine from sticking together and affecting pulverization efficiency and raw material utilization. During the pulverization process, the blower 14 operates continuously. Outside air is filtered through the filter holes 301 on the mounting base 3 and enters the mounting cavity 305. It then passes through the air supply channel 303 and the air inlet 204 into the diversion cavity 202 on the side wall of the pulverizing cylinder 2, and finally is blown into the inner cavity of the pulverizing cylinder 2 from the air outlet 203. The airflow interacts with the medicinal powder lifted by the rotating scraper 8. Qualified fine powder moves towards the discharge hopper 17 under the influence of the airflow and is eventually discharged through the discharge hopper 17 and collected by the receiving device. Larger particles that do not meet the standards are not affected by gravity. The powder is carried away by the airflow and remains in each pulverizing zone. It is then further pulverized by the pulverizing blade 13 in the corresponding pulverizing zone to achieve directional conveying and particle size screening of the powder, ensuring the uniformity of the pulverized product. At the same time, some airflow will enter the blower channel 21 of the valve plate 18 and the air inlet pipe 20, and blow into the feed channel 302 after opening the one-way valve plate 22. With the help of the connecting rod 15 driven by the rotating shaft 16 and the scraper 16 rotating and cleaning, the Chinese medicine residue on the inner wall of the feed channel 302 can be scraped off and blown into the pulverizing cylinder 2, avoiding blockage of the feed channel 302. The device achieves efficient pulverization and anti-sticking functions through multi-structure collaboration. The multi-pulverization zone design combined with the relay pulverization mechanism solves the problem of incomplete processing of a few insufficiently pulverized particles that move with the airflow. The gap at the top of the baffle 9 ensures airflow and particle circulation while providing space for stepped pulverization. The dual cleaning structure of scraper 1 8 and scraper 2 16 cleans the inner wall of the pulverizing cylinder 2 and the inner wall of the feeding channel 302 for sticky Chinese medicine, respectively, maximizing the utilization rate of raw materials. The air separation system composed of the fan 14 and the airflow channel realizes pulverization and screening simultaneously, effectively solving the defects of easy accumulation and incomplete separation of sticky Chinese medicine after pulverization in traditional devices, and meeting the needs of fine processing of sticky Chinese medicine.
