Description

Technical Field

[0001] This invention relates to the field of pulverization and processing technology, specifically to an automated equipment for low-temperature pulverization of Panax notoginseng powder. Background Technology

[0002] Existing crushing and drying equipment often operates at high temperatures and heat, which greatly affects the effective components of most materials. The article "Research and Application of Room Temperature Drying Technology for Traditional Chinese Medicine Pills" shows that the impact is even more pronounced on heat-sensitive materials such as pharmaceuticals, food, and chemicals.

[0003] Drying at temperatures below 50 degrees Celsius is called room temperature drying. Room temperature drying below 50 degrees Celsius is considered the optimal drying process. The lower the temperature, the less loss of key components occurs during drying; however, generally, the longer the drying time and the greater the energy consumption. Existing equipment and methods dry materials slowly at temperatures below 50 degrees Celsius.

[0004] Panax notoginseng powder is a product made from the rhizome of the Panax notoginseng plant, specifically from the main root. It is also known as Tianqi powder or Jinbuhuan. It is warm in nature, sweet and slightly bitter in taste, and enters the liver, stomach, and large intestine meridians. It is also called "Northern Ginseng, Southern Panax notoginseng." Ginseng is considered the best for replenishing qi, while Panax notoginseng is considered the best for replenishing blood. Panax notoginseng has always been a traditional Chinese medicine. Its functions can be summarized as "stopping bleeding, dispersing blood stasis, and relieving pain," therefore, it has historically been used as a medicine for traumatic injuries and rarely as a tonic.

[0005] The processing method of Panax notoginseng powder involves washing fresh Panax notoginseng, then sun-drying, oven-drying, or roasting it to obtain dried Panax notoginseng, which is then further pulverized to obtain Panax notoginseng powder. However, this method not only requires a lot of time, resources, and money to dry and pulverize the Panax notoginseng, but also results in the continuous loss and waste of the effective components and active substances of Panax notoginseng during the processing.

[0006] Patent CN106236803B discloses a low-temperature circulating pulverizing and drying device, comprising: a feeding port, a high-pressure airflow device, a first solid-liquid separator, a second solid-liquid separator, a powder collector, a liquid collector, a heater, a first circulating pipe, a second circulating pipe, and a protective air path. Pre-treated fresh Panax notoginseng is added to the feeding port into a negative pressure system. The fresh Panax notoginseng, carried by the high-speed airflow, forms a fluidized state and enters a closed-loop system composed of the first circulating pipe, the heater, the second solid-liquid separator, the second circulating pipe, the liquid collector, and the first solid-liquid separator. In the closed-loop system, the fresh Panax notoginseng is pulverized through collisions with the high-speed airflow, the pipes, and between particles. The fresh Panax notoginseng is dried through heat and mass exchange with the hot airflow generated by the heater, and through liquefaction and moisture collection by the liquid collector. Fresh Panax notoginseng powder that does not meet the particle size and moisture requirements continues to circulate, pulverize, and dry in the closed-loop system. Fresh Panax notoginseng powder that meets the particle size and moisture requirements enters the powder collector through a grading structure to obtain fresh Panax notoginseng powder medicinal slices.

[0007] Currently, most grading structures consist of sieves. Fresh Panax notoginseng powder that meets the particle size and moisture requirements, as well as that that does not, needs to be sieved. This easily leads to clogging at the sieves, causing the powder that does not meet the particle size and moisture requirements to block the sieves. Meanwhile, the powder that meets the particle size and moisture requirements is over-crushed by the subsequent crushing mechanism, which not only wastes the energy of the equipment but also may reduce the quality of the Panax notoginseng powder due to repeated crushing. Therefore, there is an urgent need for an automated equipment for low-temperature crushing of Panax notoginseng powder to solve the above problems. Summary of the Invention

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] (1) An automated equipment for low-temperature pulverization of Panax notoginseng powder. The main feature of the pulverizing host is that it is screenless, and the pulverizing disc and the grading impeller are driven separately and independently, so that pulverization and grading are completed in one go, thereby reducing energy consumption caused by over-pulverization, and achieving high grading efficiency. It effectively avoids over-pulverization of materials and saves energy.

[0038] (2) An automated equipment for low-temperature pulverization of Panax notoginseng powder. During the rotation of the grading impeller, the Panax notoginseng material is graded and screened by the combined action of the fan pull, centrifugal inertia, and gravity. After being screened by an air classifier, the material remaining on the screen is connected to the first chamber of the pulverizing host via a separate conveying pipe, allowing it to re-enter the pulverizing host for further pulverization. The grading accuracy is high, effectively preventing large particles from mixing into the finished product and forming white spots.

[0039] (3) An automated equipment for low-temperature pulverization of Panax notoginseng powder, wherein the pulverizing host has a pulverizing disc, hammers, and a disc groove. The outer periphery of the pulverizing disc is equipped with hammers. The pulverizing disc drives the hammers to rotate at high speed. The Panax notoginseng material entering the second chamber is pulverized under the impact and shearing action of the hammers and screws. The pulverization of Panax notoginseng material by hammers and screws alleviates the temperature rise caused by frictional heat generation. The temperature rise of the pulverized Panax notoginseng material is less than 35 degrees Celsius, which can adapt to long-term continuous production.

[0040] (4) An automated equipment for low-temperature pulverization of Panax notoginseng powder, with a compact structure, reasonable layout, and fine material selection. The particle size can be adjusted according to changes in the rotational speed of the classifying impeller and the induced draft volume. The higher the rotational speed of the classifying impeller, the finer the particle size, and vice versa. In addition, the particle size of the finished product also changes according to the adjustment of the fan's air volume; a larger air volume results in a larger particle size, and a smaller air volume results in a smaller particle size. The feed rate should also be adjusted accordingly when the particle size of the finished product is changed. The fineness of Panax notoginseng material processing is randomly adjustable.

[0041] (5) An automated equipment for low-temperature pulverization of Panax notoginseng powder, wherein the rotating fan assembly rotates together with the pulverizing disc via a connecting column, and the fan blades outside the fan ring can directly and evenly agitate the airflow introduced through the first chamber pipe into the first chamber cylinder, and during the rotation of the fan blades, the airflow will be lifted upward, thereby increasing the speed at which the pulverized Panax notoginseng material enters the grading zone for grading.

[0042] (6) An automated equipment for low-temperature pulverization of Panax notoginseng powder, wherein a cooler connected to an external cooler via a cooler pipe can further introduce cool air into the second chamber, thereby reducing the internal temperature of the second chamber. By blocking the airflow through baffles, the cool air introduced into the first chamber first contacts the bottom of the pulverizing disc and is guided along the bottom of the pulverizing disc and the baffles to the screw teeth and hammers. The introduced cool air can remove the heat generated on the hammers, toothed plates and screw teeth to the greatest extent, thereby improving the pulverization effect of Panax notoginseng.

[0043] (7) An automated equipment for low-temperature pulverization of Panax notoginseng powder, wherein the guide ring is slidably connected to the outer rod and the electric rail, and the height of the guide ring is changed by the electric rail, so that the pressure of the outer rod on the screw teeth can be changed to adjust the density of the screw teeth on the tooth plate, thereby further adjusting the fineness of pulverization and improving adjustability.

[0091] The pulse dust collector 6 includes a main box 601. The inlet of the main box 601 is connected to the upper outlet of the cyclone separator 3. A filter bag 602 is installed in the lower outlet of the main box 601. A ventilator 7 is fixedly connected to the upper outlet of the main box 601.

[0092] The working principle of this invention is as follows:

[0093] Large pieces of Panax notoginseng material are manually fed into the hopper 102 of the coarse powder mill 1, and then conveyed into the coarse crushing chamber 101 by the feeding auger 103. The motor of the feeding auger 103 is controlled by a frequency converter. By changing the motor speed of the feeding auger 103, the feeding amount is changed, thereby ensuring that the first motor 104 operates in the optimal working state. The Panax notoginseng material entering the coarse crushing chamber 101 is crushed into particles smaller than ten millimeters under the crushing action of the coarse crusher. After being screened by the screen 106, it falls to the lower side of the coarse crushing chamber 101 and is then conveyed into the main crushing unit 2 by a pneumatic conveyor.

[0094] The crushing host 2 contains a crushing disc 212, hammers 213, and a groove 214. The hammers 213 are mounted on the outer periphery of the crushing disc 212. The crushing disc 212 drives the hammers 213 to rotate at high speed. The Panax notoginseng material entering the second chamber 206 is crushed under the impact and shearing action of the hammers 213 and the groove 214.

[0095] The pulverized Panax notoginseng material is carried by the rising airflow to the grading zone for grading. The grading assembly consists of a wheel 237, a grading impeller 238, a grading shaft 236, and a third motor 234. The third motor 234 drives the grading impeller 238 to rotate. As the Panax notoginseng material rotates with the grading impeller 238, it is subjected to the combined effects of the fan pull, centrifugal inertia, and gravity. When the fan pull and centrifugal inertia are balanced, the particle size of the Panax notoginseng material is the cutting particle size. Panax notoginseng material smaller than the cutting particle size passes through the grading impeller 238 and enters the rear assembly through the third chamber 232. Panax notoginseng material larger than the cutting particle size is thrown out due to inertia and slides down the inner ring of the guide ring 225 to the second chamber 206 for re-pulverization. Panax notoginseng material with qualified particle size enters the cyclone separator 3 through the third chamber 232 to separate solid particles from air, and then falls into the air classifier 5 through the air shut-off fan 4.

[0096] After being screened by the air classifier 5, the qualified finished product falls into the collection bucket through the finished product outlet of the air classifier 5. The material on the screen is connected to the first chamber pipe 203 of the crushing host 2 through a separate conveying pipe, so that it enters the crushing host 2 for re-crushing. A small amount of ultrafine dust that cannot be handled by the cyclone separator 3 enters the pulse dust collector 6 after the cyclone separator 3 and is captured by the filter bag 602. Finally, it falls into the pulse dust collection bag. The treated clean air is discharged into the environment or exhaust duct through the pipeline via the fan 7.

[0097] The main feature of the crushing host 2 is its screenless design. The crushing disc 212 and the classifying impeller 238 are driven separately, so that crushing and classification are completed in one go, reducing energy consumption caused by over-crushing, and achieving high classification efficiency. It effectively avoids over-crushing of materials and saves energy.

[0098] As the Panax notoginseng material rotates with the classifying impeller 238, it is classified and screened by the combined action of the fan pull, centrifugal inertia force, and gravity. After being screened by the air classifier 5, the material on the screen is connected to the first chamber pipe 203 of the crushing host 2 via a separate conveying pipe, so that it can be re-entered into the crushing host 2 for re-crushing. The classification accuracy is high, which can effectively avoid large particles from being mixed into the finished product and forming white spots.

[0099] The crushing host 2 contains a crushing disc 212, hammers 213, and a groove 214. The hammers 213 are mounted on the outer periphery of the crushing disc 212. The crushing disc 212 drives the hammers 213 to rotate at high speed. The Panax notoginseng material entering the second chamber 206 is crushed under the impact and shearing action of the hammers 213 and the screw teeth 224. The crushing of Panax notoginseng material by the hammers 213 and the screw teeth 224 alleviates the temperature rise caused by frictional heat generation. The temperature rise of the crushed Panax notoginseng material is below 35 degrees Celsius, which can adapt to long-term continuous production.

[0100] Equipped with a pulse dust collector 6, the dust collected by the pulse dust collector 6 can be used as finished products, which not only ensures a clean and dust-free working environment, but also avoids the waste of crushed raw materials.

[0101] The Panax notoginseng material can be directly crushed without drying, which can save a lot of energy consumption.

[0102] With a compact structure, reasonable layout, and fine material selection, the particle size can be adjusted according to changes in the rotational speed of the classifying impeller 238 and the induced draft volume. The higher the rotational speed of the classifying impeller 238, the finer the classifying particle size, and vice versa. Furthermore, adjusting the airflow of the fan 7 also changes the finished product particle size; a larger airflow results in a larger finished product particle size, and a smaller airflow results in a smaller finished product particle size. Changing the finished product particle size requires corresponding adjustments to the feed rate. The fineness of the Panax notoginseng material processing is randomly adjustable.

[0103] By installing a heat-insulating cover 211 over the machine column 210, the amount of working heat introduced by the machine column 210 can be reduced, thereby reducing the temperature influence factors inside the second chamber 206.

[0104] The rotating fan assembly rotates together with the crushing disc 212 via the connecting column 220. The fan blades 221 on the outside of the fan ring 219 can directly and evenly agitate the airflow introduced through the first chamber pipe 203 into the first chamber cylinder 202. During the rotation of the fan blades 221, the airflow will be lifted upward, increasing the speed at which the airflow carries the crushed Panax notoginseng material into the grading zone for grading.

[0105] The external cooler connected to the cold air pipe 205 can further introduce cold air into the second chamber 206, reducing the internal temperature of the second chamber 206. By blocking the airflow through the baffle 223, the cold air introduced into the first chamber 202 first contacts the bottom of the crushing disc 212, and is guided along the bottom of the crushing disc 212 and the baffle 223 to the screw teeth 224 and the hammer block 213. The introduced cold air can remove the heat generated on the hammer block 213, the tooth plate 222 and the screw teeth 224 to the greatest extent, improving the crushing effect of Panax notoginseng.

[0106] The guide ring 225 is slidably connected to the outer rod 226 and the electric rail 208. By changing the height of the guide ring 225 through the electric rail 208, the outer rod 226 changes the pressure on the screw teeth 224, which can adjust the density of the screw teeth 224 on the tooth plate 222, thereby further adjusting the fineness of the crushing and improving the adjustability.

[0107] Through the connection between the crushing disc 212 and the hammer block 213, the inner and outer support columns 218 support the hammer block 213 from different parts, improving the stability and balance of the hammer block 213, making the contact between the hammer block 213 and the screw teeth 224 closer, and improving the effect of shearing and crushing Panax notoginseng.

[0108] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
