Description

Technical Field

[0001] This invention relates to the field of polishing technology, and in particular to a cabbage clearing ultrafine powder formulation and its preparation system and process. Background Technology

[0002] Constipation is a common problem that plagues modern people. Regular constipation can usually be relieved by taking dry powder preparations made from various Chinese herbal medicines. Since Chinese herbal medicines are mostly plant fibers, the beneficial components are not easily dissolved, and the therapeutic effect is slow. Therefore, grinding them into finer ultra-fine powders is beneficial for exerting the medicinal effect in a short time.

[0003] Current ultrafine powder production systems typically use cyclone centrifugal air jet mills for pulverization. Air jet mills utilize high-pressure airflow, such as compressed air, to accelerate materials, achieving pulverization through high-speed collisions between particles. They are the primary choice for producing fine particle sizes, narrow particle size distributions, and high purity, and are particularly suitable for heat-sensitive and high-hardness materials. During the collision pulverization process, the intense collisions and friction between dry powder particles and between particles and the inner wall of the equipment generate static electricity. This causes powder to adhere to the pipes and inner walls, not only hindering material flow but also causing the powder to adsorb and form agglomerates, creating a "buffer pad" that impedes further pulverization. Current solutions, such as the one disclosed in patent 200910034188.0, involve passing the material through an electrostatic disperser composed of positive and negative plates after pulverization, facilitating subsequent pipeline transport and packaging. However, these solutions are implemented after air jet pulverization and do not address the static electricity generated during the pulverization process itself. This static electricity severely affects the pulverization effect of the mill. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cabbage clearing ultrafine powder preparation and its preparation system and process to solve the problem of poor crushing effect caused by the inability to remove static electricity during the airflow pulverization process in the prior art.

[0005] The objective of this invention is achieved through the following technical solution: a system for preparing ultrafine powder formulations, comprising a first mixer, an air jet mill, a cyclone separator, a bag filter, and a second mixer installed sequentially. The air jet mill includes a crushing chamber, a separating chamber, a spacer chamber, a spacer cylinder, and a reciprocating mechanism. The spacer chamber divides the crushing chamber into upper and lower parts. The upper part of the crushing chamber is provided with multiple tangentially installed upper air inlet pipes, and the lower part of the crushing chamber is provided with multiple tangentially installed lower air inlet pipes. An ion air duct is provided on the crushing chamber. The spacer chamber is annular, and the lower end of the spacer cylinder is flush with the inner annular surface of the spacer chamber. A fixed, sealed connection is established. The upper edge of the partition cylinder extends horizontally inward to form an exhaust port. A sealing cone matching the exhaust port is provided inside the partition cylinder. The reciprocating mechanism drives the partition chamber and the partition cylinder to slide upward, so that the ion air pipe connects to the upper part of the crushing chamber. At this time, the partition cylinder abuts against and seals the inner wall of the crushing chamber, and the partition chamber simultaneously blocks the upper air inlet pipe. The reciprocating mechanism drives the partition chamber and the partition cylinder to slide downward, so that the ion air pipe connects to the lower part of the crushing chamber. At this time, the upper edge of the partition cylinder abuts against and seals the sealing cone, and the partition chamber simultaneously blocks the lower air inlet pipe.

[0006] Preferably, the upper part of the separation chamber is provided with a grading impeller and a first motor that drives its rotation, and the top of the separation chamber is provided with a discharge port.

[0007] Preferably, the ion air duct is located between the upper air inlet pipe and the lower air inlet pipe. The partition chamber is a hollow structure. The partition chamber is provided with a partition plate, an upper air guide pipe, and a lower air guide pipe. The partition plate horizontally divides the partition chamber into an upper air guide chamber and a lower air guide chamber. The top surface of the upper air guide chamber is provided with multiple upper exhaust ports, and the bottom surface of the lower air guide chamber is provided with multiple lower exhaust ports. The side surface of the upper air guide chamber is provided with multiple upper air inlets that match the upper air inlet pipe, and the side surface of the lower air guide chamber is provided with multiple lower air inlets that match the lower air inlet pipe. One end of the upper air guide pipe penetrates the side wall of the upper air guide chamber, and the other end is connected to the lower air guide chamber. One end of the lower air guide pipe penetrates the side wall of the lower air guide chamber, and the other end is connected to the upper air guide chamber.

[0008] Preferably, the upper edge of the crushing chamber extends inward and upward at an incline and connects to the bottom of the separation chamber. The bend in the partition cylinder forms an expanded section. The expanded section has multiple first vents on its mating surface that matches the upper edge of the crushing chamber. The middle part of the partition cylinder is a constricted section with a Laval structure. The constricted section has multiple second vents. The partition cylinder has a sealing ring that matches the second vents. The sealing ring is fixedly connected below the sealing cone.

[0009] Preferably, the upper edge of the crushing chamber extends inward and passes through the separation chamber to form a storage edge. A Venturi mixer is provided on the upper air inlet pipe and / or the lower air inlet pipe. A circulation pipe is provided on the crushing chamber. One end of the circulation pipe is connected to the suction port of the Venturi mixer, and the other end of the circulation pipe is connected to the space above the storage edge.

[0010] Preferably, the upper air chamber is provided with an upper aeration pipe that matches the upper exhaust port, and the bottom of the crushing chamber is vertically fixed with a lower aeration pipe that matches the lower exhaust port, and the lower aeration pipe and the lower exhaust port are intermittently connected.

[0011] Preferably, the reciprocating mechanism includes a push rod, a second motor, a reducer, a first connecting plate, and a second connecting plate. The push rod is located at the bottom of the interval chamber, one end of the push rod is fixedly connected to the interval chamber, and the other end of the push rod passes through the crushing chamber body and is slidably connected to it. The second motor, reducer, first connecting plate, and second connecting plate are installed outside the crushing chamber body. One end of the first connecting plate is fixedly connected to the output end of the reducer, and the other end of the first connecting plate is rotatably connected to one end of the second connecting plate. The other end of the second connecting plate is rotatably connected to the push rod, thereby the first connecting plate and the second connecting plate cooperate to form a linkage structure.

[0012] A preparation process for a cabbage clearing ultrafine powder formulation includes the following steps: S1. Add the aloe vera, lotus leaf, and kale powder that have been preliminarily ground and crushed into the first mixer and mix them. S2. The mixture is fed into the air jet mill, and high-pressure crushing airflow and ion airflow are intermittently introduced into the air jet mill to alternately remove static electricity and crush the material. S3. The gas discharged from the air jet mill is collected as solids by a cyclone separator and a bag filter. The collected powder is then mixed with maltodextrin and edible flavoring in the second mixer.

[0013] A kale-clearing ultrafine powder formulation comprises the following ultrafine powder components: aloe vera, lotus leaf, kale powder, maltodextrin, and edible flavoring.

[0014] The present invention has the following advantages: 1. By combining the air jet mill with an electrostatic eliminator in the existing process, static electricity is removed simultaneously during the air jet milling process. This not only avoids the adverse effects of static electricity on subsequent processes, but also prevents the formation of agglomerates during crushing, thereby improving the air jet milling effect and enabling the ultrafine powder traditional Chinese medicine preparations to dissolve faster and exert their effects more quickly. 2. By using the reciprocating motion of the interval chamber and interval cylinder, the ion air duct, upper air inlet pipe and lower air inlet pipe are alternately connected and blocked, so that the upper and lower parts of the air jet mill alternately carry out air jet milling and static electricity removal, realizing the continuous production of ultrafine powder. 3. By providing unique expansion and contraction sections on the spacer cylinder, the Laval principle is used to ensure the smooth flow of ion air into the airflow pulverizer, and also to achieve uniform mixing and static electricity removal of materials by the upper and lower aeration pipes.

[0017] 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, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0018] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0019] like Figure 5 As shown, a system for preparing an ultrafine powder formulation includes a first mixer 41, an air jet mill 42, a cyclone separator 43, a bag filter 44, and a second mixer 45, which are installed in sequence. The first mixer 41, the cyclone separator 43, the bag filter 44, and the second mixer 45 can all be existing equipment that can be used directly.

[0020] like Figure 1 , Figure 2 As shown, the airflow pulverizer 42 includes a crushing chamber 1, a separating chamber 2, a partition chamber 6, a partition cylinder 10, and a reciprocating mechanism 32. Both the crushing chamber 1 and the separating chamber 2 are cylindrical structures. The upper part of the separating chamber 2 is provided with a classifying impeller 5 and a first motor 3 that drives its rotation. The top of the separating chamber 2 is provided with a discharge port 4. The classifying impeller 5 and the first motor 3 installed in the separating chamber 2 are the same as the existing classifying powder selection and discharge structure. The separating chamber 2 is located above the crushing chamber 1. The diameter of the separating chamber 2 is smaller than the diameter of the crushing chamber 1. The upper edge of the crushing chamber 1 extends inward and upward at an incline and connects with the bottom of the separating chamber 2. The upper edge of the crushing chamber 1 extends inward and passes through the separating chamber 2 to form a storage edge 30. The space enclosed above the storage edge 30 and the separating chamber 2 is the storage space for the powder that has fallen after being screened by the classifying impeller 5.

[0021] like Figure 2 As shown, the partition chamber 6 is a hollow annular structure. The outer circumferential surface of the partition chamber 6 is slidably and sealed to the inner wall of the crushing chamber 1. The partition chamber 6 divides the crushing chamber 1 into upper and lower parts. The upper part of the crushing chamber 1 is equipped with the first feed pipe 39, and the lower part of the crushing chamber 1 is equipped with the second feed pipe 40. The upper part of the crushing chamber 1 is provided with multiple tangentially installed upper air inlet pipes 16, and the lower part of the crushing chamber 1 is provided with multiple tangentially installed lower air inlet pipes 17. High-pressure airflow is introduced into both the upper air inlet pipes 16 and the lower air inlet pipes 17. An ion air duct 13 is installed on the crushing chamber 1. The ion air duct 13 is a single pipe and is installed between the upper air inlet pipes 16 and the lower air inlet pipes 17. The ion air duct 13 is filled with gas sprayed from the existing ion air generator. This gas is used to neutralize the static electricity on the powder.

[0022] like Figure 3As shown, the partition chamber 6 is annular, and the lower end of the partition cylinder 10 is fixedly and sealed to the inner annular surface of the partition chamber 6. The upper edge of the partition cylinder 10 extends horizontally inward to form an exhaust port 27. The solid-containing gas after the swirling crushing of the lower half of the crushing chamber 1 is discharged into the separation chamber 2 through the partition cylinder 10. A sealing cone 22 matching the exhaust port 27 is installed inside the partition cylinder 10. The sealing cone 22 is suspended inside the partition cylinder 10 by a fixing rod 23. When the partition cylinder 10 moves downward, it can contact the sealing cone 22 to achieve sealing of the lower half of the crushing chamber 1. At this time, after the ion wind is introduced, it can contact the powder for a long time to complete the removal of static electricity.

[0023] like Figure 2 As shown, the partition chamber 6 is equipped with a partition plate 7, an upper air guide pipe 11, and a lower air guide pipe 12. The partition plate 7 horizontally divides the partition chamber 6 into an upper air guide chamber 8 and a lower air guide chamber 9. The top surface of the upper air guide chamber 8 is provided with multiple upper exhaust ports 18, and the bottom surface of the lower air guide chamber 9 is provided with multiple lower exhaust ports 19. The upper air guide pipe 11 is located inside the upper air guide chamber 8, and the lower air guide pipe 12 is located inside the lower air guide chamber 9. One end of the upper air guide pipe 11 penetrates the side wall of the upper air guide chamber 8, and the other end is connected to the lower air guide chamber 9. One end of pipe 12 penetrates the side wall of the lower air chamber 9, and the other end is connected to the upper air chamber 8. The gas that enters the lower air chamber 9 through the upper air pipe 11 will enter the crushing chamber 1 again through the lower exhaust port 19. The gas that enters the upper air chamber 8 through the lower air pipe 12 will enter the crushing chamber 1 again through the upper exhaust port 18. The upper air pipe 11 and the lower air pipe 12 are respectively matched with the ion air pipe 13. During the up and down movement, the two are respectively connected to the ion air pipe 13.

[0024] The upper air chamber 8 has multiple upper air inlets 14 on its side that match the upper air inlet pipe 16, and the lower air chamber 9 has multiple lower air inlets 15 on its side that match the lower air inlet pipe 17. During the up-and-down movement of the partition chamber 6, when the circumferential surface of the partition chamber 6 blocks one of the upper air inlet pipe 16 or the lower air inlet pipe 17, the other one is connected to the crushing chamber 1 to achieve the vortex crushing function.

[0025] like Figure 3 As shown, the upper air chamber 8 is equipped with an upper aeration pipe 20 that matches the upper exhaust port 18. The upper aeration pipe 20 is directly fixedly connected to the interval chamber 6. The bottom of the crushing chamber 1 is vertically fixed with a lower aeration pipe 21 that matches the lower exhaust port 19. When the interval chamber 6 moves down to the lowest position, the lower aeration pipe 21 and the lower exhaust port 19 are connected to realize the intermittent ventilation function between the lower aeration pipe 21 and the lower exhaust port 19. The ion wind is exhausted outward through the upper aeration pipe 20 and the lower aeration pipe 21 to achieve the fluidized bed mixing and static electricity removal effect.

[0026] The upper aeration pipe 20 and lower aeration pipe 21 will be clogged with a large amount of powder after rotation stops, requiring high-pressure airflow for clearing and venting. Due to its special properties, ion air will become ineffective after compression by an air compressor; therefore, other methods must be used to achieve high-pressure flow, such as... Figure 4 As shown, the bend in the partition cylinder 10 forms a bulging section 25. Multiple first vents 26 are provided on the mating surface of the bulging section 25 and the upper edge of the crushing chamber 1. When the bulging section 25 separates from the upper edge of the crushing chamber 1, they form a Laval structure. When the high-pressure gas in the upper part of the crushing chamber 1 passes through this Laval structure, the flow velocity at the first vents 26 increases, generating negative pressure. Consequently, the gas in the lower part of the crushing chamber 1 is attracted, also generating negative pressure. The pressure difference accelerates the ion wind flow velocity, causing it to flow downwards... The aeration pipe 21 is cleared. The middle part of the compartment cylinder 10 is a constricted tube section 24 of Laval structure. The constricted tube section 24 is provided with multiple second air ports 28. The compartment cylinder 10 is provided with a sealing ring 29 that matches the second air ports 28. The sealing ring 29 is fixedly connected to the bottom of the sealing cone 22. After the expansion section 25 is closed, the sealing ring 29 opens the second air ports 28. The gas in the upper part of the crushing chamber 1 will also generate negative pressure under the high-speed flow of gas in the compartment cylinder 10, which clears the upper aeration pipe 20.

[0027] like Figure 1 As shown, a Venturi mixer 37 is installed on each upper air inlet pipe 16, and a circulation pipe 38 is provided on the crushing chamber 1. One end of the circulation pipe 38 is connected to the suction port of the Venturi mixer 37, and the other end of the circulation pipe 38 is connected to the upper storage space of the storage line 30. The material accumulated in the storage space will be attracted into the Venturi mixer 37 by negative pressure for circulation.

[0028] like Figure 2 As shown, the reciprocating mechanism 32 can be configured with various structures. Here, a crank-slider structure is selected. The reciprocating mechanism 32 includes a push rod 31, a second motor 36, a reducer 33, a first connecting plate 34, and a second connecting plate 35. The push rod 31 is located at the bottom of the interval chamber 6. One end of the push rod 31 is fixedly connected to the interval chamber 6, and the other end of the push rod 31 passes through the crushing chamber body 1 and is slidably connected to it. The second motor 36, the reducer 33, the first connecting plate 34, and the second connecting plate 35 are installed below the crushing chamber body 1. One end of the first connecting plate 34 is fixedly connected to the output end of the reducer 33, and the other end of the first connecting plate 34 is rotatably connected to one end of the second connecting plate 35. The other end of the second connecting plate 35 is rotatably connected to the push rod 31.

[0029] The second motor 36 uses a servo motor or other motor capable of precise position control, enabling it to control the position and dwell time of the interval chamber 6. Under the action of the second motor 36, the interval chamber 6 and the interval cylinder 10 slide upward, allowing the ion air pipe 13 to connect to the upper part of the crushing chamber 1 through the lower air guide pipe 12, the interval cylinder 10 to abut against and seal the inner wall of the crushing chamber 1, and the interval chamber 6 to block the upper air inlet pipe 16. The second motor 36 also causes the interval chamber 6 and the interval cylinder 10 to slide downward, allowing the ion air pipe 13 to connect to the lower part of the crushing chamber 1 through the upper air guide pipe 11, the upper edge of the interval cylinder 10 to abut against the sealing cone 22, and the interval chamber 6 to block the lower air inlet pipe 17.

[0030] Working principle: The rotation of the second motor 36 drives the first connecting plate 34 to rotate through the reducer 33. The first connecting plate 34 drives the push rod 31 to slide up and down through the second connecting plate 35, thereby causing the partition chamber 6 and the partition cylinder 10 to slide up and down. When the partition chamber 6 and the partition cylinder 10 move to the highest position, the ion air pipe 13 connects to the lower air guide pipe 12. The ion air enters the upper part of the crushing chamber 1 through the upper air guide chamber 8 and the upper aeration pipe 20. At the same time, the expansion pipe 25 is tightly attached to the inner wall of the crushing chamber 1, the partition chamber 6 blocks the upper air inlet pipe 16, and the partition chamber 6 opens the lower air inlet pipe 17. The lower air inlet pipe 17 sprays high-pressure gas into the lower part of the crushing chamber 1 for crushing. At the same time, the gas is discharged from the discharge port 4 through the partition cylinder 10 and the classifying wheel 5. When the airflow passes through the contraction pipe 24 of the partition cylinder 10, a negative pressure is generated, which attracts the ion air in the upper part of the crushing chamber 1 and discharges it together, realizing the upper part of the crushing chamber 1. The upper half of the crushing chamber 1 is used for static electricity removal, while the lower half is used for crushing. When the partition chamber 6 and partition cylinder 10 move to the lowest position, the ion air pipe 13 connects to the upper air guide pipe 11. The ion air enters the upper half of the crushing chamber 1 through the lower air guide chamber 9 and the lower aeration pipe 21. At this time, the lower aeration pipe 21 is connected to the lower exhaust port 19. At the same time, the constriction section 24 is tightly attached to the sealing ring 29, the partition chamber 6 blocks the lower air inlet pipe 17, and the partition chamber 6 opens the upper air inlet pipe 16. The upper air inlet pipe 16 sprays high-pressure gas into the upper half of the crushing chamber 1 for crushing. At the same time, the gas is discharged from the discharge port 4 through the classifier wheel 5. When the airflow passes through the expansion section 25, it generates negative pressure, which attracts the ion air in the lower half of the crushing chamber 1 and discharges it together. This realizes the function of static electricity removal in the lower half of the crushing chamber 1 and crushing in the upper half. This alternation realizes the continuous production function of crushing and static electricity removal at the same time, which improves the crushing effect.

[0031] A preparation process for a cabbage clearing ultrafine powder formulation, such as... Figure 5 As shown, it includes the following steps: S1. The aloe vera, lotus leaf and kale powder that have been pre-ground and crushed are put into the first mixer 41 and mixed. S2. The mixture is fed into the air jet mill 42. High-pressure crushing air and ion air are intermittently introduced into the air jet mill 42 to alternately remove static electricity and crush the material. There is no need to remove static electricity through the electrode plate afterward. S3. The gas discharged from the air jet mill 42 passes through the cyclone separator 43 and the bag filter 44 for solid collection. The collected powder is then mixed with soluble maltodextrin and edible flavoring in the second mixer 45.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
