Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, and specifically relates to a grinding device and method for raw materials used in the preparation of Shengmai Yin (a traditional Chinese medicine formula). Background Technology

[0002] Shengmai Yin oral liquid belongs to the category of tonifying traditional Chinese medicine. Its main ingredients include Ophiopogon japonicus, Schisandra chinensis, and red ginseng. It can replenish qi and yin, stabilize mood, and is suitable for people with qi deficiency, no excess heat, or both qi and yin deficiency. This medicine has a high safety profile and has the effects of nourishing yin and promoting body fluid production, as well as replenishing qi and restoring pulse. For patients with clinical manifestations of both qi and yin deficiency, palpitations, shortness of breath, weak pulse, and night sweats, Shengmai Yin has a certain improving effect and can be used to raise blood pressure levels in patients with low blood pressure.

[0003] In the existing preparation process of Shengmai Yin oral liquid, a grinding device is used to grind and pulverize the raw materials, which include ginseng, ophiopogon japonicus, schisandra chinensis, and other medicinal herbs. When these herbs are compressed during grinding, they release their contained medicinal liquid. The herbs need to be ground to a fineness of approximately 300 mesh to meet the preparation requirements. However, high-speed grinding generates a significant temperature increase, which may adversely affect the efficacy of the herbs, thus impacting the final efficacy of Shengmai Yin. To reduce the impact of temperature rise during high-speed grinding on the herbs, this invention designs a raw material grinding device and method for preparing Shengmai Yin. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a raw material grinding device and method for preparing Shengmai Yin (a traditional Chinese medicine formula). The device cleverly incorporates a dual grinding chamber, a trumpet-shaped grinding body, a speed control mechanism, a filter frame, a stirring mechanism, and gaps, effectively reducing the impact of temperature rise on the medicinal materials during high-speed grinding. This ensures the efficacy of the medicinal materials and the final efficacy of Shengmai Yin, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a raw material grinding device for preparing Shengmai Yin (a traditional Chinese medicine formula), comprising a body and a vertical shaft rotatably mounted within the body. The input end of the vertical shaft is connected to a driving device. From top to bottom, the body contains an upper grinding body, a guiding mechanism, a lower grinding body, and a barrel-shaped filter frame. The upper and lower grinding bodies are funnel-shaped with opposite opening directions and are axially fixed on the vertical shaft. The guiding mechanism is fixed on the inner wall of the body. The filter frame is fixed on the vertical shaft and a stirring mechanism is provided between it and the vertical shaft. The upper grinding body has its opening facing upward, and its lower surface and the upper surface of the lower grinding body are both grinding surfaces. The two grinding surfaces form a first grinding chamber and a second grinding chamber with the guiding mechanism, respectively. A speed regulating mechanism is provided between the lower grinding body and the vertical shaft.

[0006] The gap between the first and second grinding chambers gradually narrows from top to bottom, and the minimum gap of the first grinding chamber is equal to the maximum gap of the second grinding chamber.

[0007] Furthermore, the guiding mechanism includes an upper guide plate and a lower guide plate, which are respectively trumpet-shaped grinding plates with openings at the top and bottom.

[0008] Furthermore, the speed regulating mechanism includes an air chamber opened within the vertical shaft. From bottom to top, the air chamber contains a first heat-conducting cone, a piston plate, a connecting air passage, and a monitoring component. Multiple first heat-conducting cones are fixed circumferentially and at equal intervals to the inner wall of the air chamber. Each first heat-conducting cone has a heat-conducting air passage connected to its back side. The heat-conducting air passage is opened within the lower grinding body. The piston plate is movably fitted within the air chamber. Two connecting air passages are symmetrically opened on both sides of the top of the air chamber. Each connecting air passage connects to an air bladder, which covers the vertical shaft.

[0009] Furthermore, the upper surface of the upper grinding body is a cloth surface, on which a plurality of uniformly distributed second heat-conducting cones are provided.

[0010] Furthermore, the monitoring component includes a rod fixed to the top wall of the air chamber. A horizontally arranged rectangular frame is fixed to the lower end of the rod. Two crossbars are slidably fitted inside the rectangular frame. Both crossbars have toothed grooves on their adjacent sides and mesh with a gear. The gear is rotatably mounted on the rod. The two crossbars move in opposite directions and extend to one end of the rectangular frame, where they are bonded to the centerline of the inner wall of the airbag. A linear displacement sensor is installed on one of the crossbars.

[0011] Furthermore, a pressure sensor and a temperature sensor are installed on the piston plate to monitor the real-time pressure and temperature during operation. A control panel is installed on the outer wall of the machine body. The output of the control panel is electrically connected to the drive device, and the input is connected via Bluetooth to the output of the linear displacement sensor, the pressure sensor, and the temperature sensor.

[0012] Furthermore, the agitation mechanism includes a through hole installed at the bottom of the air chamber, an arc-shaped plate above the through hole, a rope groove on the lower surface of the arc-shaped plate, and a steel wire rope slidingly connected through the rope groove. One end of the steel wire rope is tied to the bottom center of the piston plate, and the other end extends out of the through hole to the outside of the vertical shaft and is tied to the bottom edge of the lower grinding body. Multiple fixed stirring rods are fixed on the steel wire rope extending out of the vertical shaft, and a movable stirring rod is arranged between two adjacent fixed stirring rods, and the movable stirring rod slides on the steel wire rope.

[0013] Furthermore, symmetrically distributed guide blocks are provided on both sides of the piston plate, and guide grooves that cooperate with the guide blocks are provided on the inner wall of the air chamber.

[0014] Furthermore, the lower surface of the lower grinding body is coated with a heat-insulating coating, and the diameter of the lower end flared mouth of the lower grinding body is smaller than the diameter of the filter frame.

[0015] A filtration method based on the raw material grinding apparatus for preparing Shengmai Yin (a traditional Chinese medicine formula) as described above includes the following steps:

[0016] S1. Feeding: After starting the machine, add the medicinal materials to the cloth surface of the upper grinding body. As the vertical shaft rotates, the medicinal materials on the cloth surface undergo centrifugal motion and enter the guiding mechanism.

[0017] S2, Primary Grinding: The medicinal materials enter the first grinding chamber for grinding following the guide mechanism;

[0018] S3, Secondary Grinding: The medicinal materials after primary grinding fall along the lower guide plate into the second grinding chamber for further grinding;

[0019] S4. Screening and Discharge: The medicinal materials after secondary grinding fall into the filter frame, and the filtered powder is finally discharged through the outlet.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. This invention achieves graded grinding of raw medicinal materials for Shengmai Yin through the cooperation of the guiding mechanism and the upper and lower grinding bodies. It also makes reasonable use of the heat from the primary grinding based on the tip thermal effect, effectively reducing the impact of temperature rise on the medicinal materials. The medicinal materials are combed, spread out, and dried to a certain extent, which helps to improve the efficiency of subsequent grinding. The gap between the first grinding chamber and the second grinding chamber gradually narrows from top to bottom, so that the medicinal materials can be gradually refined during the grinding process, while avoiding excessive heat generated by excessive compression and friction.

[0022] 2. This invention converts the heat generated during the secondary grinding process into kinetic energy, reduces the temperature at the grinding point, ensures the efficacy of the ground medicinal powder, and generates a beneficial chain reaction. It achieves the control of the feeding speed of the secondary grinding of medicinal materials and the adjustment of the stirring range of the ground medicinal powder. Specifically, the heat at the grinding point is concentrated through the tip thermal effect. Because the air expands when heated, it will change its volume and drive the piston plate to move, realizing energy conversion. The movement of the piston plate can firstly push the upper air to expand the airbag and reduce the feed port of the second grinding chamber to achieve the purpose of speed regulation, and secondly, move one end of the steel wire rope upward, so that the position of the steel wire rope and its components in the filter frame changes, thereby adjusting the stirring position and range of the medicinal powder.

[0023] 3. By incorporating monitoring components, temperature sensors, and air pressure sensors into the speed control mechanism, this invention enables operators to intelligently monitor the machine's operation through the control panel and promptly identify any problems during operation.

[0024] Other features and advantages of the invention will be set forth in the following description. The objects and other advantages of the invention can be realized and obtained by means of the structures shown in the description and drawings. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] This invention provides a raw material grinding device for preparing Shengmai Yin (a traditional Chinese medicine formula), such as... Figure 1-3 As shown, the device includes a body 1 and a vertical shaft 2 rotatably mounted inside the body 1. Preferably, in this embodiment, the body 1 has a roughly barrel-shaped structure. For support, this embodiment has three support legs installed at the bottom of the body 1. Of course, the number of support legs can also be two, four, or other numbers. An outlet 14 is provided, through which the ground powder is discharged. The input end of the vertical shaft 2 is connected to a drive device 12, which is located between the three support legs and fixed to the bottom surface of the body 1. The outer wall of the body 1... A control panel 11 is installed on the upper part of the machine. The output terminal of the control panel 11 is electrically connected to the drive device 12. The operation of the machine body 1 can be controlled through the control panel 11. The machine body 1 is arranged from top to bottom as follows: an upper grinding body 3, a guide mechanism 4, a lower grinding body 5, and a barrel-shaped filter frame 6. The upper grinding body 3 and the lower grinding body 5 are trumpet-shaped with opposite opening directions and are axially fixed on the vertical shaft 2. The upper grinding body 3 and the lower grinding body 5 rotate with the vertical shaft 2. The guide mechanism 4 is fixed on the inner wall of the machine body 1, and the filter frame 6 is fixed on the vertical shaft 2. The lower end of the lower grinding body 5 has a flared opening diameter smaller than that of the filter frame 6. The upper grinding body 3 has an upward opening, and its lower surface and the upper surface of the lower grinding body 5 are both grinding surfaces. The guiding mechanism 4 includes an upper guide plate 41 and a lower guide plate 42. The upper guide plate 41 and the lower guide plate 42 are flared grinding plates with upper and lower openings, respectively, and their outlines match those of the upper grinding body 3 and the lower grinding body 5. The two grinding surfaces form a first grinding cavity 8 and a second grinding cavity 10 between themselves and the guiding mechanism 4. The gap between the first grinding cavity 8 and the second grinding cavity 10 is from top to bottom. The grinding chamber gradually narrows in the direction of grinding, and the minimum gap of the first grinding chamber 8 is equal to the maximum gap of the second grinding chamber 10, which gradually increases the grinding degree and achieves the function of graded grinding. The upper surface of the upper grinding body 3 is a cloth surface, on which multiple evenly distributed second heat-conducting cones 31 are provided. While the cloth is being laid, the heat generated by the first grinding chamber 8 can be guided to the cloth surface through the second heat-conducting cones 31, which can dry the medicinal materials. A speed regulating mechanism 9 for controlling the feeding speed of the second grinding chamber 10 is provided between the lower grinding body 5 and the vertical shaft 2.

[0037] The speed regulating mechanism 9 includes an air chamber 91 located within the vertical shaft 2. Air can be used to fill the air chamber 91, and an air injection port can be created by drilling holes and installing a one-way valve. From bottom to top, the air chamber 91 contains a first heat-conducting cone 92, a piston plate 93, and a connecting air passage 94. Multiple first heat-conducting cones 92 are circumferentially and evenly spaced on the inner wall of the air chamber 91. Each first heat-conducting cone 92 has a heat-conducting air passage 96 connected to its back side. The heat-conducting air passage 96 is located within the lower grinding body 5. The lower surface of the grinding body 5 is coated with a heat-insulating coating to prevent heat from being conducted downwards and to transfer heat to the air chamber 91 through the heat-conducting air passage 96 as much as possible. The piston plate 93 is movably fitted inside the air chamber 91. The piston plate 93 is provided with symmetrically distributed guide blocks 13 on both sides. The inner wall of the air chamber 91 is provided with guide grooves that cooperate with the guide blocks 13. There are two connecting air passages 94, which are symmetrically opened on the top sides of the air chamber 91. The connecting air passages 94 are connected to the air bladder 97, which covers the vertical shaft 2.

[0038] During operation, the raw materials are added to the cloth surface of the upper grinding body 3. The operator starts the machine body 1 via the control panel 11, causing the drive device 12 to rotate with the vertical shaft 2. Under the action of centrifugal force, the medicinal materials are dispersed outward, thrown out of the cloth surface, and fall onto the upper guide plate 41 of the guide mechanism 4, entering the first grinding chamber 8 for grinding. The heat generated during the grinding process can be introduced into the cloth surface through the first heat-conducting cone 81 according to the tip effect, making the medicinal materials drier. While centrifuging within the cloth surface, the cone tip can also separate the connected medicinal materials and, to a certain extent, break them, which is beneficial for subsequent grinding. Along the guide mechanism 4, the medicinal materials gradually enter the second grinding chamber 10 for grinding. At this time, the heat generated during the grinding process can be transferred through the heat-conducting air passage 96. The heat is delivered to the air chamber 91, where it accumulates due to the placement of the second heat-conducting cone 92, causing the air there to expand. Since the air chamber 91 is filled with air, the expansion pushes the piston plate 93 upward, pushing the air above the piston plate 93 into the air bag 97. After the air bag 97 expands, it shortens the width of the feed inlet of the second grinding chamber 10, thereby slowing down the feeding speed of the medicinal materials. This helps to dissipate the heat in the second grinding chamber 10. As the air in the second grinding chamber 10 is heated, it does work, converting thermal energy into kinetic energy. After the work is done, the temperature of the air decreases, and as its temperature decreases, the volume of the air gradually shrinks. The piston plate 93 gradually returns to its original position, and at this time, the air bag 97 contracts, which can increase the temperature of the medicinal materials entering the second grinding chamber 10, thereby achieving the effect of speed regulation.

[0039] The principle underlying this scheme for air expansion is Gay-Lussac's Law, which states that for a given mass of gas, under constant pressure, the volume increases (or decreases) by 1 / 273 of its volume at 0°C for every 1°C increase (or decrease) in temperature. Alternatively, for a given mass of a certain gas, under constant pressure p, the volume V is directly proportional to the thermodynamic temperature T.

[0040] In the conventional grinding process of a pulverizer, when the fineness of the pulverized material is 40-120 mesh, the temperature rises by more than 80°C. The finer the pulverized material, the higher the temperature rises. However, the fineness of the ginseng, ophiopogon japonicus, schisandra chinensis, and other medicinal materials in Shengmai Yin is around 300 mesh, and the temperature rise can reach more than 100°C. The existing ideal gas law is PV=nRT. Because the expansion and contraction of the gas in this scheme will cause the gas bladder 97 to expand accordingly, the gas pressure in the gas chamber 91 can be regarded as unchanged. Under the condition that the gas pressure (p) is constant, only the temperature changes. Under this state, there is a formula: V1 / T1=V2 / T2. It can be seen that the volume is proportional to the thermodynamic temperature. After the formula is transformed, we know that: V2=V1×T2 / T1. For every 1°C increase (or decrease) in temperature, the increase (or decrease) in volume is equal to 1 / 273 of its volume at 0°C.

[0041] Example 2

[0042] like Figure 4-5 As shown, unlike Embodiment 1, the speed control mechanism 9 also includes a monitoring component 95 for monitoring the airbag 97. It includes a rod 951 fixed to the top wall of the air chamber 91. A horizontally arranged rectangular frame 952 is fixed to the lower end of the rod 951. Two crossbars 953 are slidably fitted inside the rectangular frame 952. The two crossbars 953 are provided with toothed grooves on their adjacent sides and are meshed with a gear 954. The gear 954 is rotatably mounted on the rod 951. The two crossbars 953 move in opposite directions and are glued to the centerline of the inner wall of the airbag 97 at one end of the rectangular frame 952. A linear displacement sensor is installed on one crossbar 953. A pressure sensor and a temperature sensor are installed on the piston plate 93 for monitoring the real-time pressure and temperature during operation. The input terminal of the control panel 11 is connected to the output terminals of the linear displacement sensor, the pressure sensor, and the temperature sensor via Bluetooth.

[0043] During operation, the two crossbars 953 move closer to or further away from the rectangular frame 952 as the airbag 97 extends and retracts. The gear 954 serves as a transmission and connection mechanism. The linear displacement sensor monitors the movement distance of the crossbars 953. Combined with the data from the air pressure sensor and temperature sensor transmitted to the control panel 11, the system allows operators to determine whether the speed control mechanism 9 is operating normally, whether there is any gas leakage or excessive temperature, etc. This enables operators to control the overall operation of the machine body 1 through the control panel 11.

[0044] Example 3

[0045] like Figure 6-7As shown, unlike Embodiment 1, a stirring mechanism 7 is provided between the filter frame 6 and the vertical shaft 2 for continuous stirring of the powder to prevent it from clumping. The stirring mechanism 7 includes a through hole installed at the bottom of the air chamber 91. An arc-shaped plate 71 is provided above the through hole. A rope groove is provided on the lower surface of the arc-shaped plate 71, and a steel wire rope 72 is slidably fitted through the rope groove. One end of the steel wire rope 72 is tied to the bottom center of the piston plate 93, and the other end extends out of the through hole to the outside of the vertical shaft 2 and is tied to the bottom edge of the lower grinding body 6. Multiple fixed stirring rods 73 are fixedly fixed on the rope body of the steel wire rope 71 that extends out of the vertical shaft 2. A movable stirring rod 74 is provided between two adjacent fixed stirring rods 73, and the movable stirring rod 74 slides on the steel wire rope 72.

[0046] During operation, the stirring mechanism 7 rotates with the rotation of the vertical shaft 2. One end of the wire rope 72 moves up and down with the rise and fall of the piston plate 93, causing its length within the filter frame 6 to change continuously. The fixed stirring rod 73 and the movable stirring rod 74 on it will stir the powder when they rotate, preventing unfiltered powder from sticking together. During the stirring process, the part of the wire rope 72 located in the filter frame 6 will rotate with the vertical shaft 2 and extend outward due to centrifugal force. When one end of it rises and falls with the rise and fall of the piston plate 93, its length within the filter frame 6 will change, causing the inclination of the wire rope 72 to change as well. Therefore, the movable stirring rod 74 on the wire rope 72 will slide on it, further stirring the powder during the sliding process and increasing the stirring range.

[0047] A filtration method for a raw material grinding device used in the preparation of Shengmai Yin (a traditional Chinese medicine formula) based on Embodiment 1 includes the following steps:

[0048] S1. Feeding: After starting the machine body 1, add the medicinal materials to the cloth surface of the upper grinding body 3. As the vertical shaft 2 rotates, the medicinal materials on the cloth surface undergo centrifugal motion and enter the guiding mechanism 4.

[0049] S2, Primary Grinding: The medicinal materials enter the first grinding chamber 8 along with the guide mechanism 4 for grinding;

[0050] S3, Secondary Grinding: The medicinal materials after primary grinding fall along the lower guide plate 42 into the second grinding chamber 10 for further grinding;

[0051] S4. Screening and discharge: The medicinal materials after secondary grinding fall into the filter frame 6, and the filtered powder is finally discharged through the outlet 14.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
