Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical mixing technology, and in particular to a pharmaceutical mixing device for planting Chinese medicinal herbs. Background Technology
[0002] In the field of large-scale cultivation of Chinese medicinal herbs, the uniformity and precision of pesticide mixing directly affect the effectiveness of pest and disease control and nutrient supply. Traditional pesticide mixing devices mostly adopt a single-pipe input combined with mechanical stirring, which has inherent defects such as a single mixing path and insufficient shear strength. Especially when dealing with pesticides containing suspended particles or high viscosity, conventional stirring blades are unable to effectively break up pesticide agglomeration, resulting in substandard mixing uniformity. Although some equipment attempts to improve mixing efficiency through multi-pipe input, turbulence interference easily occurs in the confluence area of multiple pesticide streams, causing local concentration gradient imbalance and seriously affecting the homogenization effect in the initial mixing stage. Utility Model Content
[0003] This utility model relates to a mixing device for medicinal herb cultivation, which achieves deep homogenization of the medicine in a compact space through multi-stage processing of guiding, shearing, retention and recycling.
[0004] In a first aspect, this utility model provides a mixing device for medicinal herb cultivation, specifically comprising: a mixing tube; the mixing tube is a tubular structure with a closed upper end and an open lower end, and the upper end of the mixing tube is circumferentially connected to at least three medicine branch pipes with interconnected inner cavities; a mounting sleeve is fitted around the middle of the mixing tube, the mounting sleeve being used to install on the tank of the cultivation equipment; a mixing motor is fixedly installed at the upper end of the mixing tube, and a mixing shaft is vertically rotatably installed in the mixing tube, the mixing motor driving the mixing shaft to rotate.
[0005] Optionally, a mixing guide plate is spirally provided on the inner wall of the mixing tube below the drug branch, and the mixing shaft passes through the middle of the mixing guide plate.
[0006] Optionally, a convex retention ring is provided in the inner cavity of the mixing tube below the mixing guide plate, and the inner ring edge of the retention ring is higher than the outer ring edge.
[0007] Optionally, unused drug branch pipes are screwed with plugs, and used drug branch pipes are equipped with flow control valves that are connected to the corresponding drug storage tanks.
[0008] Optionally, the upper end of the mixing shaft is fixedly provided with a guide fluid that is wider at the top and narrower at the bottom. The guide fluid is located in the cavity where the drug branch pipe and the mixing pipe intersect. At least four upward-facing, evenly spaced return impellers are provided on the part of the mixing shaft corresponding to the mixing guide plate. A booster impeller is fixedly provided on the mixing shaft below the stagnation ring. When the mixing shaft rotates, the return impeller pushes the drug being mixed upward, while the booster impeller pushes the mixed drug downward.
[0009] This utility model provides a mixing device for medicinal herb cultivation, which has the following beneficial effects:
[0010] This invention significantly improves the homogenization efficiency of reagents through a multi-dimensional mixing mechanism. When multiple reagents are input, the annularly distributed branch pipes combined with flow regulation function can precisely control the ratio of different reagents, ensuring the stability and adjustability of the mixing ratio. The unique flow-guiding structure inside the mixing chamber effectively eliminates turbulent interference when multiple reagents converge, creating a uniform reagent distribution substrate in the initial mixing stage, laying the foundation for subsequent deep mixing.
[0011] In terms of hybrid dynamics optimization, the synergistic effect of the helical guide vane and the counter-rotating impeller creates a bidirectional shear vortex field. This composite flow mode not only accelerates the collision and diffusion between drug molecules, but also effectively breaks down the aggregation phenomenon of high-viscosity drugs through high-intensity shear force, making it particularly suitable for complex drug systems containing suspended particles or prone to stratification. The vertical circulation formed during the mixing process prolongs the residence time of the drug in the mixing chamber, and combined with the turbulent disturbance generated by the stagnant ring, the mixing reaction is more complete, completely solving the problem of local mixing dead zones caused by the single mixing path in traditional devices.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Example: Please refer to Figures 1 to 4 :
[0022] This utility model proposes a mixing device for medicinal herb cultivation, comprising: a mixing pipe 1; the mixing pipe 1 is a tubular structure with a closed upper end and an open lower end, and the upper end of the mixing pipe 1 is circumferentially connected to at least three medicine branch pipes 3 with interconnected inner cavities; a mounting sleeve 2 is sleeved in the middle of the mixing pipe 1, and the mounting sleeve 2 is used to install on the tank of the cultivation equipment; a mixing motor 4 is fixedly installed at the upper end of the mixing pipe 1, and a mixing shaft 5 is vertically rotatably installed in the mixing pipe 1, and the mixing motor 4 drives the mixing shaft 5 to rotate.
[0023] Among them, a mixing guide plate 101 is spirally arranged downward on the inner wall of the mixing pipe 1 below the drug branch pipe 3, and the mixing shaft 5 passes through the middle of the mixing guide plate 101.
[0024] Among them, the mixing tube 1 below the mixing guide plate 101 is provided with an upwardly protruding retention ring 102 in the inner cavity, and the inner ring edge of the retention ring 102 is higher than the outer ring edge.
[0025] The unused chemical branch pipe 3 is screwed to the end of the plug, and the used chemical branch pipe 3 is equipped with a flow control valve 301, which is connected to the corresponding chemical storage tank.
[0026] The mixing shaft 5 has a guide fluid 501 that is wider at the top and narrower at the bottom fixed at its upper end. The guide fluid 501 is located in the cavity where the drug branch pipe 3 and the mixing pipe 1 intersect. At least four upward-facing, evenly spaced return impellers 502 are provided on the part of the mixing shaft 5 corresponding to the mixing guide plate 101. A booster impeller 503 is fixed on the mixing shaft 5 below the stagnation ring 102. When the mixing shaft 5 rotates, the return impeller 502 pushes the mixed drug upward, while the booster impeller 503 pushes the mixed drug downward.
[0027] The following provides further explanation and description of the functions and effects of each structure mentioned above, so as to enable those skilled in the art to better understand this technical solution:
[0028] The mixing pipe 1 adopts a tubular structure that is closed at the top and open at the bottom. At least three agent branch pipes 3, arranged in a ring at the top, can simultaneously introduce different agents. The internal cavity connection design ensures that the agents are evenly injected into the mixing area from the circumference. The ends of unused agent branch pipes 3 are sealed with screw-in plugs, and the flow rates of each agent in the connected branch pipes are independently adjusted by the flow control valve 301, which not only ensures precise control of the mixing ratio but also allows the device to adapt to different agent combinations. The mounting sleeve 2 in the middle of the mixing pipe 1 is connected to the planting equipment tank by a sleeve fixing method, ensuring the overall stability of the device and the convenience of installation.
[0029] The key structure of the inner cavity of the mixing tube 1 further optimizes the mixing effect. Below the agent branch pipe 3, a spirally downward mixing guide plate 101 is arranged around the mixing shaft 5. Its spiral structure guides the agent to form a swirling flow along the pipe wall, while the rotation of the mixing shaft 5 drives the return impeller 502 to generate an upward reverse thrust. The swirling path of the mixing guide plate 101 and the reverse thrust of the return impeller 502 form a counter-shearing effect, which enhances the collision and dispersion of agent molecules, and can significantly improve the mixing uniformity, especially for viscous agents. The guide fluid 501 at the top of the mixing shaft 5 adopts a structure that is wider at the top and narrower at the bottom. It is located at the intersection of the agent branch pipe 3 and the mixing tube 1, which can smoothly guide the multiple input agent flows into the mixing cavity and avoid the formation of turbulent dead zones at the intersection.
[0030] The retention ring 102, positioned below the mixing guide plate 101, features an upwardly convex structure where the inner ring edge is higher than the outer ring edge. This causes a brief retention of the mixed reagent as it flows through, creating a localized turbulent zone and further extending the mixing reaction time. The retention ring 102 dynamically coordinates with the booster impeller 503 at the bottom of the mixing shaft 5: as the booster impeller 503 rotates, it accelerates and pushes the reagent downwards, while the blocking effect of the retention ring 102 forces some of the reagent to swirl upwards, forming a secondary mixing cycle. This "push-retention-return" composite flow mechanism effectively solves the problem of insufficient mixing caused by unidirectional flow in traditional mixing devices, and is particularly suitable for mixing scenarios involving easily stratified multiphase liquids. The overall structure achieves deep homogenization of the reagent within a compact space through multi-stage processing of guiding, shearing, retention, and recirculation.
[0031] Working principle:
[0032] When the device is started, the mixing motor 4 drives the mixing shaft 5 to rotate at high speed. The liquid medicine in each medicine storage tank is input into the mixing pipe 1 through the corresponding medicine branch pipe 3. The flow control valve 301 can independently adjust the flow of each branch pipe. Unused branch pipes are sealed with screw plugs to ensure the flexibility of the mixing ratio and the system's sealing. When the medicine enters the top of the mixing pipe 1 through the medicine branch pipe 3, the guide fluid 501 at the upper end of the mixing shaft 5, with its streamlined structure that is wider at the top and narrower at the bottom, smoothly guides the multiple streams of medicine to the center of the mixing chamber, avoiding turbulence or local accumulation at the confluence due to differences in flow velocity, thus forming a preliminary uniform mixing layer.
[0033] The reagent entering the inner cavity of the mixing tube 1 forms a downward rotating vortex along the tube wall under the helical guidance of the mixing guide plate 101. At the same time, the mixing shaft 5 drives the return impeller 502 to rotate at high speed, generating an upward reverse thrust, which pushes some of the reagent back to the mixing guide plate 101 area. The swirling path of the mixing guide plate 101 and the reverse thrust of the return impeller 502 create a counter-shearing effect, forcing the reagent molecules to collide and disperse violently in the bidirectional vortex, which has a strong breaking effect, especially on high viscosity or easily stratified reagents, and significantly improves the mixing uniformity.
[0034] After passing through the mixing guide plate 101, the reagent flows through the retention ring 102. The convex structure of this ring creates a local obstruction at its inner edge, causing a decrease in reagent velocity and temporary retention. The inclined inner wall of the retention ring 102 guides some of the reagent to diffuse outwards, creating turbulent disturbances and prolonging the mixing reaction time. Simultaneously, the booster impeller 503 at the bottom of the mixing shaft 5 continuously pushes the reagent downwards, but due to the obstruction of the retention ring 102, some of the reagent is forced to swirl upwards, merging again with the newly flowing reagent, forming a secondary cycle of "push-retention-return" mixing. This process not only enhances the longitudinal mixing of the reagent but also effectively avoids sedimentation or stratification.
[0035] Finally, the mixed agent is stably output from the lower opening of the mixing pipe 1 under the continuous drive of the booster impeller 503. The entire mixing process achieves multi-dimensional and multi-stage deep mixing within a limited space through the smooth distribution of the guide fluid 501, the shear enhancement of the mixing guide plate 101 and the return impeller 502, the turbulent disturbance of the retention ring 102, and the cyclic drive of the booster impeller 503. The device is particularly suitable for complex agent systems that require precise proportioning in the cultivation of Chinese medicinal herbs. It can achieve a highly homogenized mixing effect in a short time. At the same time, the stable connection between the mounting sleeve 2 and the tank of the cultivation equipment ensures the continuity and stability of the mixing operation.
