Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine preparation production technology, and in particular to a raw material pulverizing device for traditional Chinese medicine preparation production. Background Technology

[0002] In the production of traditional Chinese medicine preparations, the pulverization of raw materials is a crucial pretreatment step, and its effectiveness directly affects the subsequent extraction, mixing, and the efficacy and quality of the finished product. Therefore, it is generally necessary to use a specialized traditional Chinese medicine pulverizer to pulverize the raw materials.

[0003] Currently, existing Chinese medicine pulverizers typically consist of a pulverizing chamber, a movable toothed disc, a fixed toothed disc, and a drive motor. Through the high-speed relative motion between the movable and fixed toothed discs, impact and shearing forces are generated between the discs, thereby achieving the purpose of pulverizing Chinese medicinal materials to the target particle size.

[0004] However, due to the high-speed airflow typically involved in the pulverizing process and the adhesive nature of medicinal powders, a significant amount of powder always remains on the inner wall of the pulverizing chamber, the toothed disc structure, and the built-in screen after processing. To avoid cross-contamination between different batches or types of medicinal materials and to ensure drug safety and quality, a thorough cleaning of the equipment is usually required after each change in production batch or variety. Current cleaning methods primarily rely on manual labor, which is not only time-consuming and labor-intensive but also inefficient, leading to prolonged equipment downtime and impacting overall production efficiency.

Detailed Implementation

[0025] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0026] The following describes a raw material pulverizing device for the production of traditional Chinese medicine preparations according to an embodiment of this application, with reference to the accompanying drawings.

[0027] like Figures 1-8 As shown in the embodiment of this application, the raw material pulverizing equipment for the production of traditional Chinese medicine preparations may include a support frame 1, a pulverizing mechanism 2, and a cleaning mechanism 3.

[0028] Among them, the support frame 1 is set vertically relative to the ground.

[0029] The crushing mechanism 2 includes a crushing chamber 201, a feed hopper 202, a discharge hopper 203, a rotary crushing component 204, and a screening component 205.

[0030] The crushing chamber 201 is disposed on the support frame 1, the feed hopper 202 is disposed on the crushing chamber 201, the discharge hopper 203 is disposed on the support frame 1 and communicates with the crushing chamber 201, the screening component 205 is disposed inside the crushing chamber 201, and the rotary crushing component 204 is disposed on the support frame 1, with the crushing part of the rotary crushing component 204 extending into the screening component 205.

[0031] It should be noted that, in this embodiment, the support frame 1 is provided with a matching slot at the corresponding crushing chamber 201 and the discharge hopper 203 to realize the communication function between the discharge hopper 203 and the crushing chamber 201.

[0032] Understandably, the screening component 205 is used to screen the Chinese herbal raw materials after they have been crushed by the rotary crushing component 204, so that qualified powder is filtered out and discharged through the discharge hopper 203, while unqualified raw materials continue to be crushed in the crushing chamber 201.

[0033] The cleaning mechanism 3 includes a water spraying component 301, a protective component 302, and a water pumping component 303.

[0034] The water spraying component 301 is disposed inside the crushing chamber 201 and connected to the rotary crushing component 204. The protective component 302 is connected to both the water spraying component 301 and the rotary crushing component 204. The water pumping component 303 is disposed at the bottom of the support frame 1 and communicates with the water spraying component 301.

[0035] Understandably, the protective component 302 protects the water spray component 301 when it is not being cleaned, preventing powder from entering the interior of the water spray component 301 when the Chinese herbal raw materials are being crushed, or preventing the high-speed moving Chinese herbal raw materials from causing wear to the water spray component 301.

[0036] Specifically, in the process of producing traditional Chinese medicine preparations, relevant personnel first dry some traditional Chinese medicinal materials with moderate fiber content (such as Codonopsis pilosula, Astragalus membranaceus, Panax notoginseng, Glycyrrhiza uralensis, Crataegus pinnatifida, pearl, Ganoderma lucidum, American ginseng, wolfberry and other root, rhizome, fruit and some mineral medicinal materials). (Dried materials are not easy to stick together during the crushing process, and the powder has good flowability after crushing, which is convenient to filter through the sieve component 205). After drying, these traditional Chinese medicine raw materials can be crushed using this equipment.

[0037] In actual operation, the staff first continuously feeds the Chinese herbal raw materials from the feed hopper 202 into the crushing chamber 201. Then, the rotary crushing component 204 is started. The high-speed relative motion of the rotary crushing component 204 continuously impacts, shears and crushes the Chinese herbal raw materials. Qualified Chinese herbal powder particles are filtered out through the screening component 205 and discharged through the discharge hopper 203. Unqualified raw materials continue to remain in the crushing chamber 201 for crushing until they meet the target particle size and are discharged, thus obtaining Chinese herbal powder with uniform size and good crushing effect.

[0038] After all the Chinese herbal raw materials have been pulverized, relevant personnel can open the pulverizing chamber 201 and manually adjust the protective component 302 to remove the protective shielding of the water spray component 301. Then, the pulverizing chamber 201 is closed again, and finally, the water pumping component 303 is activated to draw clean water or cleaning solution into the water spray component 301. The water spray component 301 sprays clean water or cleaning solution in different directions. At the same time, the rotating crushing component 204 is activated to rotate, so that multiple streams of water are sprayed synchronously, thereby covering and cleaning the pulverizing chamber 201, the rotating crushing component 204, and the screening component 205 in an all-round way. The wastewater from the cleaning is discharged from the outside of the pulverizing chamber 201 through the screening component 205 and the discharge hopper 203. After cleaning, relevant personnel can open the pulverizing chamber 201 again and wait for it to dry.

[0039] This equipment not only ensures the cleaning effect and avoids cross-contamination between different batches or varieties of medicinal materials, significantly improving the product quality and safety of traditional Chinese medicine preparations, but also saves time and effort in cleaning, reduces manual intervention, and eliminates the need to disassemble the sieve component 205, thereby greatly improving cleaning efficiency.

[0040] In one embodiment of this application, such as Figure 2 and Figure 3 As shown, the crushing chamber 201 includes a shell 2011, a cover 2012, and a sleeve 2013.

[0041] The housing 2011 is mounted on the upper side of the support frame 1, the cover 2012 is pivotally connected to the housing 2011, and the cover 2012 is locked and fixed to the housing 2011 by a locking member (not specifically marked in the figure). The sleeve 2013 is disposed on the outer wall of the housing 2011, and the sleeve 2013 is coaxially disposed with the housing 2011.

[0042] It should be noted that the housing 2011 described in this embodiment has openings on the front and lower ends, respectively, for communicating with the feed hopper 202 and the discharge hopper 203.

[0043] It should be noted that the locking component described in this embodiment includes a threaded rod, a threaded sleeve, a rotating wheel, and a locking plate. The threaded rod is pivotally connected to the outer side of the housing 2011, the threaded sleeve is threadedly connected to the threaded rod, the rotating wheel is mounted on the threaded sleeve, and the locking plate is connected to the front side of the cover 2012. The locking plate has a groove that is compatible with the threaded rod.

[0044] When locking the cover 2012, after the cover 2012 is fastened to the housing 2011, rotate the threaded rod into the slot of the clamping plate, and then rotate the rotating wheel to make the threaded sleeve cooperate with the threaded rod to clamp the clamping plate, thereby keeping the cover 2012 stable.

[0045] It should be noted that a sealing ring is provided on the inner side of the cover 2012 described in this embodiment. When the cover 2012 is closed, the sealing ring and the screening component 205 can achieve a good sealing effect. The feed hopper 202 is installed on the outer side of the cover 2012, and the feeding function can be realized through the feed hopper 202.

[0046] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the rotary crushing assembly 204 includes a rotating disk 2041, a rotating shaft 2042, a plurality of first crushing teeth 2043, a plurality of second crushing teeth 2044, a driving component 2045, a first synchronous pulley 2046, a second synchronous pulley 2047, and a synchronous belt 2048.

[0047] The rotating disk 2041 is rotatably connected to the housing 2011 via the rotating shaft 2042, which passes through the housing 2011 and extends to the outside of the sleeve 2013. The rotating disk 2041 has a cavity inside. Multiple first crushing teeth 2043 are connected to the rotating disk 2041 and arranged in a ring array. Multiple second crushing teeth 2044 are connected to the cover 2012 and arranged in a ring array. The multiple second crushing teeth 2044 and the multiple first crushing teeth 2043 are staggered. The driving component 2045 is installed on the upper side of the support frame 1. The first synchronous pulley 2046 is connected to the output end of the driving component 2045. The second synchronous pulley 2047 is connected to one end of the rotating shaft 2042. The synchronous belt 2048 is sleeved between the first synchronous pulley 2046 and the second synchronous pulley 2047.

[0048] It should be noted that, in this embodiment, the first crushing tooth 2043 and the second crushing tooth 2044 are both arranged in two rings, and the number of the first crushing tooth 2043 corresponds to the number of the second crushing tooth 2044. When the cover 2012 is closed, the second crushing tooth 2044 in the inner ring is located between the two rings of the first crushing tooth 2043, and the first crushing tooth 2043 in the outer ring is located between the two rings of the second crushing tooth 2044, thus achieving an alternating distribution.

[0049] It should be noted that the driving component 2045 described in this embodiment can be a drive motor, and a bearing is provided between the rotating shaft 2042 and the housing 2011 to realize the rotation function of the rotating shaft 2042 and the rotating disk 2041.

[0050] Specifically, when pulverizing Chinese herbal raw materials, relevant personnel first close the cover 2012 and lock it with the locking device. Then, the raw materials are fed into the feed hopper 202, allowing them to fall into the shell 2011. Next, the drive unit 2045 is activated. The drive unit 2045 drives the rotating shaft 2042 to rotate through the first synchronous wheel 2046, the second synchronous wheel 2047, and the synchronous belt 2049. The rotating shaft 2042 drives the rotating disk 2041 to rotate, and the rotating disk 2041 drives the first pulverizing tooth 2043 to rotate. Through the high-speed relative motion between the first pulverizing tooth 2043 and the second pulverizing tooth 2044, the Chinese herbal raw materials are continuously impacted, sheared, and crushed, thereby forming Chinese herbal powder.

[0051] In one embodiment of this application, such as Figure 2 and Figure 4 As shown, the screening assembly 205 includes a screen cylinder 2051 and multiple arc-shaped plates 2052.

[0052] The screen cylinder 2051 is detachably connected to the housing 2011 and is sleeved on the outside of the rotating disk 2041. Multiple arc-shaped plates 2052 are respectively connected to the rotating disk 2041 and are attached to the inner side of the screen cylinder 2051.

[0053] It should be noted that the sieve cylinder 2051 and the housing 2011 described in this embodiment can be detachably connected by bolts, so that sieve cylinders 2051 with different apertures can be quickly replaced when different particle sizes of Chinese medicine powder are required.

[0054] It is understandable that the curved surface of the arc plate 2052 contacts the inner side of the screen cylinder 2051. The arc surface can reduce the contact area and frictional resistance with the screen cylinder 2051, thereby ensuring the high-speed and smooth operation of the equipment.

[0055] Specifically, during the crushing process, the arc plate 2052 rotates synchronously with the rotating disk 2041. The crushed Chinese herbal raw materials fall onto the surface of the screen cylinder 2051. The arc plate 2052 pushes and squeezes the raw material powder along the surface of the screen cylinder 2051, so that qualified powder can be quickly screened out. Unqualified raw materials are lifted upward by the arc plate 2052 and re-enter the first crushing tooth 2043 and the second crushing tooth 2044 for repeated crushing.

[0056] In one embodiment of this application, such as Figure 6 As shown, the water spray assembly 301 includes a first water inlet pipe 3011, an annular pipe group 3012, a plurality of first nozzles 3013, a plurality of second nozzles 3014, and a retaining ring 3015.

[0057] The first water inlet pipe 3011 is installed inside the rotating shaft 2042. The annular pipe group 3012 is installed inside the rotating disk 2041 and is connected to the first water inlet pipe 3011. Multiple first nozzles 3013 are respectively connected to the annular pipe group 3012 and pass through the rotating disk 2041. Multiple second nozzles 3014 are respectively connected to the first water inlet pipe 3011 and are located inside the housing 2011. The multiple second nozzles 3014 are arranged in a ring array. The baffle ring 3015 is connected to the multiple second nozzles 3014.

[0058] It should be noted that the annular pipe assembly 3012 described in this embodiment consists of two annular pipes and multiple connecting pipes. The annular pipes are connected to the first water inlet pipe 3011 through the connecting pipes. The two annular pipes correspond to the positions of the two rings of second pulverizing teeth 2044 respectively. The number and position of the first nozzles 3013 correspond to the second pulverizing teeth 2044, so that the water flow sprayed by the first nozzles 3013 can clean the first pulverizing teeth 2043 and the second pulverizing teeth 2044.

[0059] A sealing element (not shown in the figure) is provided between the first nozzle 3013 and the rotating disk 2041 to ensure airtightness and prevent Chinese medicine powder or water from entering the cavity.

[0060] The second nozzle 3014 is located in the middle of the housing 2011 and is arranged in a ring array. Each second nozzle 3014 passes through the retaining ring 3015 and is aligned between the gaps of two adjacent first crushing teeth 2043, so that the water sprayed by the second nozzle 3014 can reach the surface of the screen cylinder 2051 to clean the screen cylinder 2051.

[0061] The first water inlet pipe 3011 is made of stainless steel and is fixed to the rotating shaft 2042 by welding to ensure stability.

[0062] In one embodiment of this application, such as Figure 5 and Figure 7 As shown, the protective component 302 includes a protective plate 3021, a protective cylinder 3022, and a limiting part 3023.

[0063] Among them, the protective plate 3021 is pivotally connected to the rotating disk 2041, the protective plate 3021 is adapted to the annular pipe assembly 3012, and a first through hole is opened at the first nozzle 3013. The protective cylinder 3022 is connected to the protective plate 3021, and the retaining ring 3015 is attached to the inner wall of the protective cylinder 3022. The protective cylinder 3022 is opened at the second nozzle 3014, and the limiting part 3023 is connected to the protective cylinder 3022 and the first water inlet pipe 3011 respectively.

[0064] It should be noted that a bearing is provided between the protective plate 3021 and the rotating disk 2041 described in this embodiment. At the same time, multiple sliding grooves adapted to the protective plate 3021 are also provided on the rotating disk 2041, so that the protective plate 3021 can be engaged in the sliding grooves, ensuring stability while realizing the rotation function.

[0065] A sealing element (not shown in the figure) is provided between the retaining ring 3015 and the protective cylinder 3022 to ensure sealing and prevent raw material powder or water from entering the interior of the protective cylinder 3022 through the second through hole.

[0066] In one embodiment of this application, such as Figure 7 As shown, the limiting part 3023 includes a gear ring 30231, a pull rod 30232, a fixing block 30233, a gear 30234, and two springs 30235.

[0067] Among them, the toothed ring 30231 is connected to one end of the first water inlet pipe 3011, the pull rod 30232 is installed through the end of the protective cylinder 3022, the fixing block 30233 is connected to one end of the pull rod 30232, the gear 30234 is connected to the fixing block 30233 and is adapted to the toothed ring 30231, and the two springs 30235 are respectively connected between the fixing block 30233 and the protective cylinder 3022.

[0068] It should be noted that the pull rod 30232 described in this embodiment has a T-shaped structure, and the part of the pull rod 30232 that penetrates the protective cylinder 3022 is a square rod. A sealing element (not shown in the figure) is provided at the connection between the protective cylinder 3022 and the pull rod 30232 to ensure sealing.

[0069] Specifically, when not being cleaned, the first through hole and the first nozzle 3013, and the second through hole and the second nozzle 3014 are staggered, so that the protective plate 3021 can shield the first nozzle 3013, and the protective cylinder 3022, together with the retaining ring 3015, can shield the second nozzle 3014. This prevents powder from entering the interior of the first nozzle 3013 and the second nozzle 3014 when pulverizing Chinese herbal raw materials, or prevents the high-speed moving Chinese herbal raw materials from impacting and wearing the first nozzle 3013 and the second nozzle 3014, thereby reducing maintenance costs and extending the service life of the equipment.

[0070] When it is necessary to clean the inside of the crushing chamber 201, the relevant personnel can first open the cover 2012, then pull the lever 30232 to disengage the gear 30234 from the gear ring 30231. Next, rotate the lever 30232, which will cause the protective cylinder 3022 and the protective plate 3021 to start rotating until the first through hole is aligned with the first nozzle 3013 and the second through hole is aligned with the second nozzle 3014. Then release the lever 30232, and the fixing block 30233, in conjunction with the thrust of the spring 30235, will drive the gear 30234 to reset and engage inside the gear ring 30231, thus locking and fixing the protective cylinder 3022 and the protective plate 3021. Then close the cover 2012 again to start cleaning.

[0071] In one embodiment of this application, such as Figure 8 As shown, the water pumping assembly 303 includes a water tank 3031, a water pump 3032, a second water inlet pipe 3033, and a sealed bearing 3034.

[0072] Water tank 3031 is installed inside the lower side of support frame 1, water pump 3032 is installed on water tank 3031 and its inlet is connected to the inside of water tank 3031, second inlet pipe 3033 is connected between water pump 3032 outlet and one end of first inlet pipe 3011, and sealed bearing 3034 is installed between second inlet pipe 3033 and first inlet pipe 3011.

[0073] It is understandable that the sealing bearing 3034 allows the second water inlet pipe 3033 to remain stationary while the first water inlet pipe 3011 rotates.

[0074] Specifically, during cleaning, a certain amount of clean water or cleaning solution is first injected into the water tank 3031. Then, the water pump 3032 is started to draw clean water or cleaning solution from the water tank 3031. The clean water or cleaning solution enters the first water inlet pipe 3011 through the second water inlet pipe 3033, and then is diverted to the annular pipe group 3012 through the first water inlet pipe 3011. Then, it is sprayed out through the first nozzle 3013 and the second nozzle 3014 respectively. The water flow sprayed from the first nozzle 3013 can rinse the first crushing tooth 2043, the second crushing tooth 2044 and the cover 2012 in the horizontal direction. The water flow sprayed from the second nozzle 3014 can rinse the screen cylinder 2051 and the rotating disk 2041 in the vertical direction of the first nozzle 3013.

[0075] Simultaneously, the drive unit 2045 is activated to control the rotating disk 2041 to rotate, causing multiple water streams to rotate and spray synchronously, thereby comprehensively covering and cleaning the crushing chamber 201, the rotating crushing component 204, and the screening component 205, avoiding any blind spots in the cleaning process. The wastewater from the cleaning process is discharged outside the housing 2011 through the screen cylinder 2051 and the discharge hopper 203. After cleaning for a period of time, the relevant personnel turn off the water pump 3032 and reopen the crushing chamber 201 to allow it to dry.

[0076] In summary, the raw material pulverizing equipment for traditional Chinese medicine preparation production proposed in this application, through the integrated design of the cleaning mechanism and the pulverizing mechanism, can automatically and thoroughly clean the inside of the pulverizing chamber after the pulverizing operation is completed, thereby improving cleaning efficiency and reducing labor costs and labor intensity.
