Description

Technical Field

[0001] This invention relates to the field of oral solution preparation technology, and in particular to a stirring system for preparing oral solutions. Background Technology

[0002] Oral solutions are clear liquid preparations made by dissolving drugs in a suitable solvent. They are rapidly absorbed and convenient to take, making them especially suitable for children, the elderly, and those with difficulty swallowing. This type of dosage form, administered in liquid form, avoids the disintegration process of tablets, allowing the drug to be absorbed directly into the gastrointestinal tract.

[0003] Currently, the core step in the commercial production of oral solutions is the mixing of materials. Existing mixing equipment mostly adopts a traditional single mixing structure, which can only achieve simple circumferential stirring. This presents several problems in the preparation of oral solutions. The current mixing device has a single stirring method and cannot form an upward and downward convection circulation of materials, which easily leads to the stratification and precipitation of materials. This results in insufficient contact between the main materials, excipients and solvents, prolongs the stirring time, and easily causes problems such as incomplete dissolution and uneven mixing of local materials. This, in turn, affects the concentration uniformity and product stability of the oral solution. At the same time, materials tend to adhere to the inner wall of the mixing vessel during the stirring process, causing material residues and agglomeration, reducing the utilization rate of raw materials, increasing production costs, and causing an imbalance in the mixing ratio. Furthermore, during the feeding process, some unmixed materials enter the discharge pipe before the stirring is completed, which affects the overall quality of the prepared solution. Summary of the Invention

[0004] This invention addresses the problems of existing stirring devices, which suffer from a single stirring method, inability to create vertical convection circulation of materials, easy stratification and sedimentation, insufficient contact between main and auxiliary materials and solvent, prolonged stirring time, and the tendency for localized incomplete dissolution and uneven mixing, thus affecting the concentration uniformity and product stability of oral solutions. Furthermore, materials tend to adhere to the inner wall of the stirring vessel during stirring, causing material residue and clumping, reducing raw material utilization, increasing production costs, and causing imbalances in the mixing ratio. Additionally, during the feeding process, some unmixed materials enter the discharge pipe prematurely before stirring is complete, further affecting the overall quality of the prepared solution. Therefore, this invention provides a stirring system for preparing oral solutions.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions: This invention provides a stirring system for preparing oral solutions, the stirring system comprising: A stirred tank, the stirred tank being used for stirring and processing in the preparation of oral solutions; A stirring mechanism is installed on the top of the mixing vessel, with the stirring end penetrating through the top of the vessel and extending into the interior of the mixing vessel. The stirring mechanism is used for fully stirring the materials and intercepting incompletely dissolved materials. A vibration cleaning device is installed on the outside of the mixing vessel to assist in vibration cleaning of the inner wall of the vessel. A protective shell is attached to the outside of the vibration cleaning device and connected to the outside of the mixing tank. A controller is installed on the front side of the mixing vessel to control the coordinated operation of the various components.

[0006] Furthermore, the mixing vessel includes a vessel body, support legs, and a discharge assembly. The support legs are fixedly connected to the bottom of the vessel body. The top of the vessel body is provided with a feed inlet and a temperature sensor.

[0009] Furthermore, the stirring mechanism includes a servo motor, a stirring shaft, a flow assembly, and a bottom interception assembly. The servo motor is fixedly installed on the top of the vessel body. The upper end of the stirring shaft is fixedly connected to the output end of the servo motor, and the lower end extends into the interior of the vessel body. Multiple sets of stirring blades are fixedly installed on the lower side surface of the stirring shaft, and a rubber scraper is fixedly installed on the side surface of one set of stirring blades. The flow assembly is spirally wound on the surface of the stirring shaft to promote the up-and-down circulation of materials. A bottom interception assembly is installed at the bottom of the stirring shaft to intercept impurities when liquid is discharged from the bottom.

[0010] Furthermore, the rubber scraper is made of food-grade rubber material, and the rubber scraper is in contact with the inner wall and bottom surface of the vessel, and the bottom end of the rubber scraper is in contact with the outer surface of the intercepting filter.

[0011] Furthermore, the flow assembly includes a spiral tube, a first filter screen, and a second filter screen. The spiral tube is fixedly sleeved on the outside of the stirring shaft. When the stirring shaft rotates, it drives the spiral tube to rotate, generating an upward thrust that pushes the material at the bottom of the vessel upward to fully mix with the material at the top. The first filter screen and the second filter screen are respectively fixedly installed at the bottom and top ends of the spiral tube.

[0012] Furthermore, the bottom interception assembly includes a rotating seat, a rotating shaft, an interception filter, and a support frame.

An interception filter is fixedly mounted on the bottom end of the rotating seat. The interception filter is sleeved on the outer surface of the support frame. The support frame is fixedly disposed on the inner wall of the bottom of the vessel.

[0013] Furthermore, the support frame is positioned directly above the connection between the discharge pipe and the vessel body, and the bottom end of the support frame has multiple through holes arranged in a circumferential ring. The bottom end of the intercepting filter screen covering the top of the support frame is attached to the inner wall surface of the bottom of the vessel body.

[0014] The vibration cleaning device includes a hydraulic cylinder, a moving ring, a vibration assembly, a guide column, and a linear bearing. The hydraulic cylinder is fixedly installed at the bottom of the protective shell, the moving ring is fixedly installed at the top of the output end of the hydraulic cylinder, the vibration assembly is installed on the moving ring, the linear bearing is installed on the moving ring, the linear bearing is slidably sleeved on the surface of the guide column, and the guide column is fixedly installed on the inner wall of the protective shell.

[0015] Furthermore, the vibration assembly includes an eccentric motor, which is installed in a mounting slot. A cam is installed at the output end of the eccentric motor. A fixed plate is provided on one side of the cam and mounted on the inner wall of the moving ring via a fixed column. A sliding column slides through the side surface of the fixed plate. A vibration head is fixedly connected to one end of the sliding column facing the vessel body. The other end of the sliding column passes through the fixed plate and is fixedly connected to the push shell. The push shell is elastically connected to the fixed plate via an elastic spring sleeved on the surface of the sliding column.

[0016] Furthermore, the controller is a PLC controller, which is equipped with a touch screen and an emergency stop button. The controller is electrically connected to the servo motor, electric push rod, valve, hydraulic cylinder, and eccentric motor to control the coordinated operation of each component.

[0017] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0018] The positive and progressive effects of this invention are as follows: The aforementioned stirring system for preparing oral solutions, based on the action of the stirring mechanism, can form an upper and lower convection circulation through the stirring blades and the spiral flow component, breaking the static stratification of materials, and allowing the main ingredients, auxiliary materials and solvents to fully contact and mix, effectively avoiding the problems of insufficient local dissolution and uneven mixing, improving the quality of solution preparation, and significantly reducing material residue agglomeration. At the same time, with the linkage of the vibration cleaning device and the stirring mechanism, it can also effectively clean the inner wall of the vessel, avoiding material residue on the inner wall of the vessel, improving the utilization rate of raw materials, and improving production efficiency and product quality. Furthermore, during the stirring process, the bottom interception filter screen intercepts undissolved fine impurities to prevent them from entering the discharge pipe. In addition, the discharge component is equipped with an electric push rod to drive the sealing plug to move. During the feeding and stirring stages, the discharge port can be strictly sealed to ensure that all materials are confined within the vessel. This prevents materials from entering the discharge component in advance, which would lead to insufficient mixing, and also prevents materials from entering the discharge pipe in advance, ensuring that the subsequently discharged materials are always evenly mixed.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. Example

[0041] like Figure 1-14 As shown, the stirring system includes: a stirring vessel 1, which is used for stirring and processing the preparation of oral solutions; A stirring mechanism 2 is installed on the top of the stirring vessel 1, and the stirring end passes through the top of the vessel body 11 and extends into the interior of the stirring vessel 1. The stirring mechanism 2 is used for fully stirring the material and intercepting the incompletely dissolved material. Vibration cleaning device 4 is installed on the outside of the mixing vessel 1 and is used to perform auxiliary vibration cleaning on the inner wall of the vessel body 11. The protective shell 3 is attached to the outside of the vibration cleaning device 4 and connected to the outside of the mixing tank 1. Controller 5 is installed on the front side of the mixing vessel 1 and is used to control the coordinated operation of various components.

[0042] In the embodiments of this application, such as Figures 1-6 As shown, the mixing vessel 1 includes a vessel body 11, support legs 12, and a discharge assembly 13. The support legs 12 are fixedly connected to the bottom of the vessel body 11. The top of the vessel body 11 is equipped with a feed inlet and a temperature sensor. The temperature sensor is electrically connected to the controller 5 to facilitate real-time monitoring of the temperature of the material inside the vessel body 11. The discharge assembly 13 is located at the center of the bottom of the vessel body 11 and is used to discharge the prepared oral solution and to intercept materials and liquids before stirring that may enter the discharge assembly 13 prematurely. The operator adds various materials (including main ingredients, auxiliary ingredients, and solvents) required for preparing the oral solution into the vessel body 11 according to the specified ratio through the feed inlet at the top of the mixing vessel 1. During the addition process, the connection between the discharge pipe 131 and the vessel body 11 is sealed by a sealing plug 134, preventing materials from entering the discharge assembly 13 prematurely and ensuring that all materials are mixed within the vessel body 11.

[0043] As a preferred method, refer to Figure 11 As shown, the discharge assembly 13 includes a discharge pipe 131, a receiving pipe 132, an electric push rod 133, a sealing plug 134, and a valve 135. The discharge pipe 131 is located at the bottom of the vessel body 11. A valve 135 is installed at the end of the discharge pipe 131. The receiving pipe 132 is fixedly connected to the bottom of the connection between the discharge pipe 131 and the vessel body 11. An electric push rod 133 is installed at the bottom of the receiving pipe 132. A sealing plug 134 is fixedly connected to the output end of the electric push rod 133. The controller 5 controls the electric push rod 133 to retract, causing the sealing plug 134 to move downwards and disengage from the connection between the discharge pipe 131 and the vessel body 11, thus releasing the seal on the discharge pipe 131. Subsequently, the controller 5 controls the valve 135 at the end of the discharge pipe 131 to open, and the oral solution prepared in the vessel body 11 is discharged through the discharge pipe 131 at the bottom of the vessel body 11. During the discharge process, the interception filter 263 of the bottom interception component 26 intercepts impurities in the finished solution, ensuring that the discharged oral solution is free of impurities and meets the purity standards.

[0044] The receiving tube 132 is vertically arranged, and a sealing plug 134 is slidably connected to the inner cavity of the receiving tube 132. The sealing plug 134 can be moved to the connection between the discharge tube 131 and the vessel body 11 under the drive of the electric push rod 133 to seal.

[0045] Preferred, Reference Figures 12-14As shown, the stirring mechanism 2 includes a servo motor 21, a stirring shaft 22, a flow assembly 25, and a bottom interception assembly 26. The servo motor 21 is fixedly installed on the top of the vessel body 11. The upper end of the stirring shaft 22 is fixedly connected to the output end of the servo motor 21, and the lower end extends into the interior of the vessel body 11. Multiple sets of stirring blades 23 are fixedly installed on the lower side surface of the stirring shaft 22, one set of stirring blades 23 having a rubber scraper 24 fixedly installed on its side surface. The flow assembly 25 is spirally wound on the surface of the stirring shaft 22 to promote the upward and downward circulation of materials. The bottom interception assembly 26 is installed at the bottom of the stirring shaft 22 to intercept impurities when liquid is discharged from the bottom. After the materials are added, the operator issues a stirring command through the touch screen of the controller 5. After receiving the command, the controller 5 controls the servo motor 21 of the stirring mechanism 2 to start, driving the stirring shaft 22 to rotate at a uniform speed. When the stirring shaft 22 rotates, the multiple sets of stirring blades 23 on its lower side surface rotate synchronously, stirring the materials in the vessel body 11 in all directions, breaking up the material stratification, promoting full contact between the main material, auxiliary material and solvent, and accelerating the dissolution of materials. Meanwhile, the food-grade rubber scraper 24 fixed on one of the stirring blades 23 rotates synchronously with the stirring blade 23. Since the rubber scraper 24 is in close contact with the inner wall of the vessel 11, the bottom surface of the vessel 11 and the outer surface of the intercepting filter 263, it can scrape off the material adhering to the inner wall, bottom and intercepting filter 263 of the vessel 11 during the rotation process, avoid material residue and clumping, make full use of the material and prevent residual material from affecting the purity of the oral solution.

[0046] The rubber scraper 24 is made of food-grade rubber material. The rubber scraper 24 is in contact with the inner wall and bottom surface of the vessel body 11, and the bottom end of the rubber scraper 24 is in contact with the outer surface of the intercepting filter 263.

[0047] Preferred, Reference Figure 13 As shown, the flow assembly 25 includes a spiral tube 251, a first filter screen 252, and a second filter screen 253. The spiral tube 251 is fixedly sleeved on the outside of the stirring shaft 22. When the stirring shaft 22 rotates, it drives the spiral tube 251 to rotate, generating an upward thrust that pushes the material at the bottom of the vessel 11 upward to mix fully with the material at the top. The first filter screen 252 and the second filter screen 253 are respectively fixedly installed at the bottom and top ends of the spiral tube 251.

[0048] In practical use, as the stirring shaft 22 rotates, the spiral tube 251 spirally wound on the surface of the stirring shaft 22 generates an upward thrust, pushing the material at the bottom of the vessel 11 upward. This causes the material at the bottom to mix with the material at the top to form a convective circulation, breaking the static stratification of the material and achieving uniform mixing of materials in all areas of the vessel 11, thus avoiding the problems of insufficient dissolution and uneven mixing of local materials.

[0049] The bottom interception assembly 26 includes a rotating seat 261, a rotating shaft 262, an interception filter 263, and a support frame 264. The rotating seat 261 is rotatably mounted on the surface of the rotating shaft 262, which is fixedly connected to the bottom end of the stirring shaft 22. The interception filter 263 is fixedly mounted on the bottom end of the rotating seat 261. The interception filter 263 is sleeved on the outer surface of the support frame 264. The support frame 264 is fixedly disposed on the inner wall of the bottom of the vessel body 11.

[0050] During the use of this technical solution, incompletely dissolved fine impurities will settle to the bottom of the vessel 11 during the stirring process and be intercepted by the intercepting filter 263, preventing impurities from entering the discharge component 13 and further improving the purity of the oral solution. The multiple through holes distributed in a ring around the bottom of the support frame 264 can ensure the normal flow of materials and will not affect the material circulation and subsequent discharge due to the setting of the intercepting filter 263, and ensure the stable placement and use of the intercepting filter 263.

[0051] The support frame 264 is located directly above the connection between the discharge pipe 131 and the vessel body 11. The bottom end of the support frame 264 has multiple through holes distributed in a circumferential ring. The bottom end of the intercepting filter 263 covering the top of the support frame 264 is attached to the inner wall surface of the bottom of the vessel body 11.

[0052] Among them, reference Figures 8-10 As shown, the vibration cleaning device 4 includes a hydraulic cylinder 41, a moving ring 42, a vibration assembly 43, a guide column 44, and a linear bearing 45. The hydraulic cylinder 41 is fixedly installed at the bottom of the protective shell 3. The moving ring 42 is fixedly installed at the top of the output end of the hydraulic cylinder 41. The vibration assembly 43 is installed on the moving ring 42. The linear bearing 45 is installed on the moving ring 42. The linear bearing 45 is slidably sleeved on the surface of the guide column 44. The guide column 44 is fixedly installed on the inner wall of the protective shell 3.

[0053] The vibration assembly 43 includes an eccentric motor 431, which is installed in a mounting slot 421. A cam 432 is installed at the output end of the eccentric motor 431. A fixed plate 434 is provided on one side of the cam 432 and is installed on the inner wall of the moving ring 42 via a fixed column 433. A sliding column 436 slides through the side surface of the fixed plate 434. A vibration head 437 is fixedly connected to one end of the sliding column 436 facing the vessel body 11. The other end of the sliding column 436 passes through the fixed plate 434 and is fixedly connected to the push shell 438. The push shell 438 is elastically connected to the fixed plate 434 via an elastic spring 435 sleeved on the surface of the sliding column 436.

[0054] In this operation, the controller 5 controls the eccentric motor 431 to start. The output end of the eccentric motor 431 drives the cam 432 to rotate. During the rotation of the cam 432, it continuously impacts the push shell 438. Under the impact force of the cam 432, the push shell 438 drives the sliding column 436 to move. At the same time, the elastic spring 435 sleeved on the surface of the sliding column 436 can be reset after the push shell 438 is impacted. The sliding column 436 can slide back and forth along the fixed plate 434, thereby driving the vibrating head 437 at one end of the sliding column 436 towards the outer wall of the vessel 11 to repeatedly impact the outer wall of the vessel 11. The impact of the vibrating head 437 generates high-frequency vibration, which is transmitted to the inner wall of the vessel 11. This causes the material residues attached to the inner wall of the vessel 11 (especially the dead corner residues that are difficult to scrape off by the stirring blade 23 and the rubber scraper 24) to fall off and fall into the vessel 11 to participate in subsequent stirring and mixing, thereby improving the material utilization rate and avoiding the growth of bacteria in the vessel 11 or affecting the preparation of the next batch of products. Meanwhile, the elastic spring 435 sleeved on the surface of the sliding column 436 can be reset after the push shell 438 is impacted, ensuring that the reciprocating impact action of the vibrating head 437 is continuous and stable; the protective shell 3 is covered on the outside of the vibration cleaning device 4, which can effectively protect the vibration component 43 from external interference, and at the same time block the noise generated by the vibration, reducing the impact on the outside world. At the same time, while the vibration component 43 is working, the hydraulic cylinder 41 can drive the moving ring 42 to move up and down along the guide column 44, which can adjust the cleaning position of the vibration component 43 to adapt to the cleaning needs of the inner wall of the vessel 11 at different heights, effectively improving the cleaning effect and greatly reducing the adhesion of materials.

[0055] The controller 5 is a PLC controller 5, which is equipped with a touch screen and an emergency stop button. The controller 5 is electrically connected to the servo motor 21, electric push rod 133, valve 135, hydraulic cylinder 41 and eccentric motor 431, respectively, to control the coordinated work of each component and realize the automated control of processes such as stirring, vibration, cleaning and discharge.
