Description

Technical Field

[0001] The invention relates to the technical field of pulverizing processing, and in particular to automated equipment for low-temperature pulverizing of notoginseng powder materials. Background Art

[0002] Existing crushing and drying equipment is often accompanied by high temperature and heat during operation, which has a great impact on the effective ingredients of most materials. The article "Research and Application of Room-Temperature Drying Technology for Traditional Chinese Medicine Pills" shows that the impact on heat-sensitive materials such as medicines, foods, and chemicals is more obvious.

[0003] Drying at a temperature below 50 degrees Celsius is called normal temperature drying. Normal temperature drying below 50 degrees Celsius is the best drying process. The lower the temperature, the less the loss of target components in the drying process, but generally speaking, the longer the drying time, the greater the drying energy consumption. Existing equipment and methods are slow to dry materials at temperatures below 50 degrees Celsius.

[0004] Panax notoginseng powder is a product of the rhizome of Panax notoginseng. It is made from the main root of Panax notoginseng. It is also known as Tianqi powder and 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 and southern Panax notoginseng. Ginseng is the best for replenishing qi, and Panax notoginseng is the best for replenishing blood. Panax notoginseng has always been a traditional Chinese medicine. The function of Panax notoginseng can be summarized in six words: "stop bleeding, disperse blood stasis, and relieve pain". Therefore, Panax notoginseng has always been used as a medicine for wounds and rarely as a tonic.

[0005] The processing method of Panax notoginseng powder is as follows: fresh Panax notoginseng is washed and then dried in the sun, oven or roasted to obtain dried Panax notoginseng, which is then further crushed to obtain Panax notoginseng powder. However, this method not only requires a lot of time, material resources and financial resources to dry and crush Panax notoginseng, but also in the process of processing, the effective ingredients and active substances of Panax notoginseng are constantly lost and wasted.

[0006] The patent with the announcement number CN106236803B discloses a low-temperature circulation crushing and drying device, including: a feeding port, a strong airflow device, a first solid-liquid separator, a second solid-liquid separator, a powder collector, a liquid collector, a temperature riser, a first circulation pipeline, a second circulation pipeline and a protective gas path. The pre-treated fresh Panax notoginseng is added to the feeding port and enters the negative pressure system. The fresh Panax notoginseng forms a fluidized state with the high-speed airflow and enters the closed circulation system composed of the first circulation pipeline, the temperature riser, the second solid-liquid separator, the second circulation pipeline, the liquid collector and the first solid-liquid separator; in the closed circulation system, the fresh Panax notoginseng is crushed by mutual collision with the high-speed airflow, the pipeline and the particles; the fresh Panax notoginseng is dried by heat and mass exchange with the hot airflow generated by the temperature riser, and the liquid collector liquefies and collects water; the fresh Panax notoginseng powder that does not meet the particle size and moisture requirements continues to be circulated, crushed and dried in the closed circulation system, and the fresh Panax notoginseng powder that meets the particle size and moisture requirements enters the powder collector through the graded structure to obtain the fresh Panax notoginseng powder Chinese medicine slices.

[0007] At present, the grading structure is mostly composed of sieves. Fresh Panax notoginseng powder that meets the particle size and moisture requirements and fresh Panax notoginseng powder that does not meet the particle size and moisture requirements need to be screened through the sieve, which can easily lead to congestion at the sieve, thereby causing the fresh Panax notoginseng powder that does not meet the particle size and moisture requirements to block the sieve, while the fresh Panax notoginseng powder that meets the particle size and moisture requirements is subsequently over-crushed by the crushing mechanism, which not only wastes the energy consumption of the equipment, but also repeated crushing may cause the quality of the Panax notoginseng powder to decrease. Therefore, there is an urgent need for an automated equipment for low-temperature crushing of Panax notoginseng powder materials to solve the above-mentioned problems. Summary of the invention

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] (1) An automated equipment for low-temperature crushing of Panax notoginseng powder. The main feature of the crushing machine is the screen-free design. The crushing disk and the grading impeller are driven separately, so that the crushing and grading can be completed at one time to reduce the energy consumption caused by over-crushing. The grading efficiency is high, which can effectively avoid over-crushing of materials and save energy.

[0038] (2) An automated equipment for low-temperature crushing of Panax notoginseng powder. The Panax notoginseng material is subjected to the combined effects of fan drag, centrifugal inertia and gravity during the rotation of the grading impeller, and then screened by an air flow screen. The screened material is connected to the first warehouse pipe of the crushing main machine through a separate conveying pipeline, and can be re-crushed by the crushing main machine. The grading accuracy is high, which can effectively prevent large particles from mixing into the finished product to form white spots.

[0039] (3) An automated equipment for low-temperature crushing of Panax notoginseng powder materials, wherein a crushing disk, hammer blocks, and disk slots are arranged in the crushing main unit, and hammer blocks are installed on the outer periphery of the crushing disk. The crushing disk drives the hammer blocks to rotate at high speed, and the Panax notoginseng materials entering the second silo are crushed under the impact and shearing action of the hammer blocks and screw teeth. The Panax notoginseng materials are crushed by the hammer blocks and screw teeth, so that the temperature rise caused by frictional heat is alleviated. The temperature rise of the Panax notoginseng materials during crushing is less than 35 degrees Celsius, which can adapt to long-term continuous production.

[0040] (4) An automated equipment for low-temperature crushing of Panax notoginseng powder, with a compact structure, reasonable layout, fine material selection, and particle size adjustment that can be adjusted according to changes in the rotation speed of the grading impeller and the change in the induced draft. The higher the rotation speed of the grading impeller, the finer the grading particle size, and vice versa. In addition, the particle size of the finished product can also be changed by adjusting the air volume of the fan. If the air volume is large, the particle size of the finished product is large, and if the air volume is small, the particle size of the finished product is small. If the particle size of the finished product is changed, the feed amount should also change accordingly. The processing fineness of Panax notoginseng material can be adjusted randomly.

[0041] (5) An automated equipment for low-temperature crushing of Panax notoginseng powder, wherein a rotating fan assembly rotates together with a crushing disk through a connecting column, and the fan blades arranged outside the fan ring can directly and evenly stir the airflow introduced through the first silo tube into the first silo, and during the rotation of the fan blades, the airflow is driven to rise, thereby increasing the speed at which the crushed Panax notoginseng material is driven by the airflow to enter a grading area for grading.

[0042] (6) An automated equipment for low-temperature crushing of Panax notoginseng powder. The cold air can be further introduced into the second silo through an external refrigerator connected to a cold air pipe to reduce the internal temperature of the second silo. The cold air introduced into the first silo first contacts the bottom of the crushing disk through the blocking plate to the airflow, and is guided along the bottom of the crushing disk and the baffle to the screw teeth and hammer block. The introduced cold air can take away the heat generated by the hammer block, tooth plate and screw teeth to the greatest extent, thereby improving the effect of crushing Panax notoginseng.

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

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

[0093] The bulk Panax notoginseng material is manually put into the hopper 102 of the coarse powder machine 1, and then transported into the coarse crushing chamber 101 by the feeding auger 103. The motor of the feeding auger 103 is controlled by a frequency converter. The feeding amount is changed by changing the motor speed of the feeding auger 103, so that the first motor 104 works in the best working state. The Panax notoginseng material entering the coarse crushing chamber 101 is crushed into particles less than ten millimeters under the crushing action of the coarse crusher. After being screened by the screen 106, it falls into the lower side of the coarse crushing chamber 101 and is sucked into the inside of the crushing host 2 by wind conveying.

[0094] The crushing main machine 2 contains a crushing disk 212, a hammer block 213, and a disk groove 214. The crushing disk 212 is equipped with a hammer block 213 on the periphery. The crushing disk 212 drives the hammer block 213 to rotate at a high speed. The Panax notoginseng material entering the second silo 206 is crushed under the impact and shearing action of the hammer block 213 and the disk groove 214.

[0095] The crushed Panax notoginseng material is carried to the classification area by the rising air flow for classification. The classification component is composed of a wheel 237, a classification impeller 238, a classification shaft 236 and a third motor 234. The third motor 234 drives the classification impeller 238 to rotate. The Panax notoginseng material is acted upon by the fan drag, centrifugal inertia and gravity in the process of following the rotation of the classification impeller 238. When the fan drag is balanced with the centrifugal inertia, the particle size of the Panax notoginseng material is the cutting particle size. The Panax notoginseng material smaller than the cutting particle size passes through the classification impeller 238 and enters the rear end component through the third bin pipe 232. The Panax notoginseng material larger than the cutting particle size is thrown out due to inertia, and slides along the inner ring of the guide ring 225 to the second bin 206 for re-crushing. The Panax notoginseng material with qualified particle size enters the cyclone separator 3 through the third bin pipe 232 to separate the solid particles from the air, and falls into the air flow screen 5 through the fan 4.

[0096] After being screened by the airflow screen 5, the qualified finished products fall into the collection barrel from the finished product port of the airflow screen 5, and the screened materials are connected to the first warehouse pipe 203 of the crushing main machine 2 through a separate conveying pipeline, so that they enter the crushing main machine 2 for re-crushing. A small amount of ultra-fine dust that cannot be processed by the cyclone separator 3 enters the pulse dust collector 6 after the cyclone separator 3 and is captured by the filter bag 602, and finally falls into the pulse powder collection bag, and the treated clean air is discharged to the environment or the exhaust duct through the pipeline and the fan 7.

[0097] The main feature of the crushing main unit 2 is the screen-free design. The crushing disc 212 and the grading impeller 238 are driven separately, so that crushing and grading are completed at one time to reduce the energy consumption caused by over-crushing. The grading efficiency is high, which effectively avoids over-crushing of materials and saves energy.

[0098] In the process of following the rotation of the classification impeller 238, the Panax notoginseng material is subjected to the combined action of the fan drag, centrifugal inertia and gravity for classification and screening, and then screened by the air flow screen 5. The screened material is connected to the first warehouse pipe 203 of the crushing main machine 2 through a separate conveying pipeline, and can be re-crushed by the crushing main machine 2. The classification accuracy is high, which can effectively prevent large particles from mixing into the finished product to form white spots.

[0099] The crushing main machine 2 contains a crushing disk 212, a hammer block 213, and a disk groove 214. The crushing disk 212 is equipped with a hammer block 213 on the periphery. The crushing disk 212 drives the hammer block 213 to rotate at a high speed. The Panax notoginseng material entering the second silo 206 is crushed under the impact and shearing action of the hammer block 213 and the screw tooth 224. The Panax notoginseng material is crushed by the hammer block 213 and the screw tooth 224, which alleviates the temperature increase caused by frictional heat. The temperature rise of the Panax notoginseng material crushing is less than 35 degrees Celsius, which can adapt to long-term continuous production.

[0100] Equipped with a pulse dust collector 6, the dust recovered by the pulse dust collector 6 can be used as a finished product, 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] The structure is compact, the layout is reasonable, the material selection is fine, and the particle size can be adjusted according to the change of the rotation speed of the classification impeller 238 and the change of the induced air volume. The higher the rotation speed of the classification impeller 238, the finer the classification particle size, and vice versa. In addition, the particle size of the finished product can also change according to the adjustment of the air volume of the fan 7. The larger the air volume, the larger the particle size of the finished product, and the smaller the air volume, the smaller the particle size of the finished product. Changing the particle size of the finished product, the feeding amount should also change accordingly. The processing fineness of Panax notoginseng material can be adjusted randomly.

[0103] By disposing a cover shell 211 made of heat insulating material outside the machine column 210 , it is possible to reduce the amount of working heat introduced into the machine column 210 and reduce the temperature influencing factors in the second silo 206 .

[0104] The rotating fan assembly rotates together with the crushing disk 212 through the connecting column 220. The fan blades 221 outside the fan ring 219 can directly and evenly stir the airflow introduced through the first warehouse pipe 203 into the first warehouse tube 202, and in the process of the rotation of the fan blades 221, the airflow will be driven to rise, thereby increasing the speed at which the crushed Panax notoginseng materials are driven by the airflow to enter the grading area for grading.

[0105] An external refrigerator can be connected to the cold air pipe 205 to further introduce cold air into the second silo 206 to reduce the internal temperature of the second silo 206. The cold air introduced into the first silo 202 first contacts the bottom of the crushing disk 212 through the blocking piece 223 to the airflow, and is guided along the bottom of the crushing disk 212 and the blocking piece 223 to the screw teeth 224 and the hammer block 213. The introduced cold air can take away the heat generated by the hammer block 213, the tooth plate 222 and the screw teeth 224 to the greatest extent, thereby improving the effect of crushing Panax notoginseng.

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

[0107] Through the connection between the crushing disk 212 and the hammer block 213, the inner and outer pillars 218 support the hammer block 213 from different positions, thereby 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 the Panax notoginseng.

[0108] 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.
