Description

Technical Field

[0001] This utility model relates to the field of mixing and stirring devices, and in particular to a mixing and stirring device for liquid medicines. Background Technology

[0002] Liquid pharmaceutical mixing and stirring devices are mainly used to uniformly mix various liquid pharmaceuticals. They are widely used in the pharmaceutical, chemical, and food and beverage industries. In the pharmaceutical field, they can be used to produce various oral liquids and injections, ensuring the uniform distribution of active ingredients and guaranteeing drug quality and efficacy. In the chemical industry, they can be used to produce various chemical reagents, coatings, and other products, allowing different components to fully blend and improving product performance. Through the action of the stirring device, liquid pharmaceuticals with different properties are thoroughly mixed to meet stringent requirements for product quality and performance. Currently, liquid pharmaceutical mixing and stirring devices typically require the following technologies in practical applications:

[0003] 1. High-efficiency mixing technology: It has a mixing method and structure that can quickly and uniformly mix liquid agents, such as using specially shaped stirring blades to generate fluid flow in different directions to promote agent mixing;

[0004] 2. Precision dosage control technology: This technology ensures the accurate addition and control of the dosage of various liquid agents, which can be achieved through high-precision metering pumps, flow sensors, etc., to guarantee the accuracy of the mixing ratio.

[0005] 3. Sealing and Leakage Prevention Technology: Preventing leakage of liquid agents, especially for some toxic, harmful or expensive agents, by using reliable sealing materials and structures, such as mechanical seals and packing seals, to ensure production safety and environmental friendliness.

[0006] Currently, various equipment and methods are used to achieve the mixing and stirring of liquid pharmaceuticals. Some companies use ordinary electric stirring devices equipped with simple stirring blades, which are driven by a motor to rotate and stir.

[0007] However, the above method has a prominent drawback: existing stirring devices usually lack bottom stirring function. When mixing liquid agents, some different liquid agents are prone to sinking due to differences in density, solubility and other characteristics. Since the bottom agent usually lacks bottom stirring function, the bottom agent cannot be fully exchanged and mixed with the upper agent, which will result in obvious concentration differences in the vertical direction of the mixed agent. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a liquid medicine mixing and stirring device, which solves the technical problem that stirring devices usually lack bottom stirring function. When mixing liquid medicines, some different liquid medicines are prone to sinking due to differences in density, solubility and other characteristics. The lack of bottom stirring function usually prevents the bottom medicine from fully exchanging and mixing with the upper medicine, which leads to obvious concentration differences in the vertical direction of the mixed medicine.

[0009] To achieve the above objectives, this utility model provides a liquid medicine mixing and stirring device, including a mixing tank, a sleeve rotatably connected inside the mixing tank, a stirring rod rotatably connected inside the sleeve, two shaft pins fixedly connected inside the stirring rod, a tilting push platform fixedly connected to the inner surface of the mixing tank, the two shaft pins rotatably connected to the outer surface of the tilting push platform, a triangular limiting block fixedly connected to the outer surface of the tilting push platform, both shaft pins and the triangular limiting block being on the same horizontal line, and an inclined guide groove being formed inside the tilting push platform.

[0010] Preferably, a bearing is fitted inside the sleeve, and the stirring rod is fitted onto the inner surface of the bearing.

[0011] Preferably, a drive motor is fixedly connected to the upper end of the mixing tank, and a stirring rod is sleeved on the outer surface of the drive motor, the stirring rod being rotatably connected inside the mixing tank.

[0012] Preferably, the sleeve is fixedly connected to the lower end of the stirring rod, and a funnel-shaped feeding hopper is fixedly connected to the outer surface of the mixing tank.

[0013] Preferably, a scale strip is fixedly connected to the inner surface of the funnel-shaped feeding hopper, and a discharge valve is fixedly connected to the lower end of the funnel-shaped feeding hopper, the discharge valve being fixedly connected to the outer surface of the mixing tank.

[0014] Preferably, a discharge valve is fixedly connected inside the mixing tank, and a control box is fixedly connected to the outer surface of the mixing tank, wherein the control box is compatible with the drive motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The drive motor drives the stirring rod and the sleeve to rotate synchronously, achieving basic mixing. At the same time, the tumbling rod inside the sleeve moves with the revolution. When the shaft pin contacts the triangular limiting block on the flipping push platform, the shaft pin is forced to change its tilt angle along the inclined plane due to the path constraint of the inclined guide groove, triggering the rotation of the tumbling rod. During the periodic movement of the shaft pin along the inclined guide groove, the tumbling rod rotates or moves axially on the basis of the revolution. Its end rotates at the bottom of the mixing tank, turning the deposited agent upward. At the same time, the stirring rod continuously stirs the upper liquid, forming vertical convection. The periodic collision of the triangular limiting block further breaks up the clumps of material. Finally, through the synergistic effect of horizontal vortex and vertical tumbling, efficient mixing without dead angles is achieved, which can avoid the phenomenon of liquid agent settling at the bottom during mixing.

[0017] 2. Liquid agents are added through a funnel-shaped feeding hopper. The scale on the inner surface of the funnel-shaped feeding hopper helps the operator understand the amount of agent to be added. The agent flows into the mixing tank along the funnel-shaped feeding hopper. When there is too much material, the discharge valve at the lower end of the funnel-shaped feeding hopper is opened to discharge the excess material. The operator can accurately add the corresponding volume of agent according to the scale, which helps to ensure the quality stability and consistency of the mixed agent. Even if there is a deviation in the amount of material added during operation, it can be discharged and corrected in time through the discharge valve. Attached Figure Description

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0028] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in this application embodiment effectively solves the technical problem that stirring devices usually lack bottom stirring function. When mixing liquid agents, some different liquid agents are prone to sinking due to differences in density, solubility, and other characteristics. The lack of bottom stirring function prevents the bottom agent from fully exchanging and mixing with the upper agent, resulting in significant concentration differences in the vertical direction after mixing. The overall concept is as follows: A liquid agent mixing and stirring device includes a mixing tank 11, a sleeve 12 rotatably connected inside the mixing tank 11, a stirring rod 13 rotatably connected inside the sleeve 12, two shaft pins 14 fixedly connected inside the stirring rod 13, and a tilting push platform 15 fixedly connected to the inner surface of the mixing tank 11. The two shaft pins 14 are rotatably connected to the outside of the tilting push platform 15. On the surface of the rotating push table 15, a triangular limiting block 16 is fixedly connected to the outer surface. Two shaft pins 14 are on the same horizontal line as the triangular limiting block 16. An inclined guide groove 17 is opened inside the rotating push table 15. A bearing 18 is sleeved inside the sleeve 12. The stirring rod 13 is sleeved on the inner surface of the bearing 18. A drive motor 19 is fixedly connected to the upper end of the mixing tank 11. A stirring rod 21 is sleeved on the outer surface of the drive motor 19. The stirring rod 21 is rotatably connected inside the mixing tank 11. The sleeve 12 is fixedly connected to the lower end of the stirring rod 21. A funnel-shaped feeding hopper 22 is fixedly connected to the outer surface of the mixing tank 11. Liquid medicine is added through the funnel-shaped feeding hopper 22. The scale strip 23 on the inner surface of the funnel-shaped feeding hopper 22 can help the operator understand the amount of medicine added. The medicine flows into the mixing tank 11 along the funnel-shaped feeding hopper 22.

[0030] A graduated strip 23 is fixedly connected to the inner surface of the funnel-shaped feeding hopper 22. A discharge valve 24 is fixedly connected to the lower end of the funnel-shaped feeding hopper 22. The discharge valve 24 is fixedly connected to the outer surface of the mixing tank 11. A discharge valve 25 is fixedly connected inside the mixing tank 11. When there is too much material being fed, the discharge valve 24 at the lower end of the funnel-shaped feeding hopper 22 is opened to discharge the excess material. After the liquid medicine is stirred and mixed evenly in the mixing tank 11, it is discharged through the discharge valve 25 for use.

[0031] A control box 26 is fixedly connected to the outer surface of the mixing tank 11. The control box 26 is compatible with the drive motor 19. By pressing the control button on the control box 26, the drive motor 19 is started and begins to work. The drive motor 19 drives the stirring rod 21 and the sleeve 12 to rotate synchronously, achieving basic mixing. At the same time, the turning rod 13 inside the sleeve 12 moves with the revolution (the turning push table 15 consists of an upper ring and a base, and the shaft pin 14 rotates on the lower surface of the ring). When the shaft pin 14 contacts the triangular limit block 16 on the turning push table 15, it is guided by the inclined guide groove 17. Due to the path constraint, the shaft pin 14 is forced to change its tilt angle along the inclined plane, triggering the rotation of the stirring rod 13. During the periodic movement of the shaft pin 14 along the inclined guide groove 17, the stirring rod 13 rotates or moves axially on the basis of revolution. Its end rotates at the bottom of the mixing tank 11, turning the deposited agent upward. At the same time, the stirring rod 21 continuously stirs the upper liquid, forming vertical convection. The periodic collision of the triangular limiting block 16 further breaks up the clumps of material. Finally, through the synergistic effect of horizontal vortex and vertical stirring, efficient mixing without dead angles is achieved.

[0032] To address the problems existing in the prior art, this utility model provides a liquid medicine mixing and stirring device. The drive motor 19 drives the stirring rod 21 and the sleeve 12 to rotate synchronously to achieve basic stirring. At the same time, the turning rod 13 inside the sleeve 12 moves with the revolution. When the shaft pin 14 contacts the triangular limiting block 16 on the turning push platform 15, the shaft pin 14 is forced to change the tilt angle along the inclined plane due to the path constraint of the inclined guide groove 17, triggering the rotation of the turning rod 13. During the periodic movement of the shaft pin 14 along the inclined guide groove 17, the turning rod 13 rotates or moves axially on the basis of the revolution. Its end rotates at the bottom of the mixing tank 11, turning the deposited medicine upward. At the same time, the stirring rod 21 continuously stirs the upper liquid, forming vertical convection. The periodic collision of the triangular limiting block 16 further breaks up the clumps of material. Finally, through the synergistic effect of horizontal vortex and vertical turning, efficient mixing without dead angles is achieved, which can avoid the phenomenon of liquid medicine settling at the bottom during mixing.

[0033] Mixing tank 11: As the core container of the entire device, it provides space for mixing liquid reagents. It internally houses components such as the sleeve 12, the turning rod 13, and the stirring rod 21, and is connected to the funnel-shaped feeding hopper 22 and the discharge valve 25 to realize the input and output of reagents. The inner surface of the mixing tank 11 provides a fixed position for the turning and pushing platform 15, which, together with other components, ensures the smooth progress of the mixing process and ensures that the liquid reagents are mixed within it.

[0034] Sleeve 12: Rotatably connected inside the mixing tank 11 and fixedly connected to the lower end of the stirring rod 21. On the one hand, it rotates synchronously with the stirring rod 21, providing the power basis for the revolution of the turning rod 13; on the other hand, the bearing 18 and the turning rod 13 are sleeved inside it, so that the turning rod 13 can move relative to it, and cooperate with the stirring rod 21 and the turning rod 13 to realize different forms of stirring action.

[0035] Stirring rod 13: Located inside sleeve 12, it is rotatably connected to sleeve 12 via bearing 18. During stirring, it revolves with sleeve 12. When shaft pin 14 interacts with triangular limiting block 16, it triggers rotation or axial movement. Its end can penetrate deep into the bottom of mixing tank 11, turning the agent deposited at the bottom upwards. This, combined with the stirring rod 21's action of agitating the upper liquid, forms vertical convection, promoting thorough mixing of the liquid agent in the vertical direction.

[0036] Shaft pin 14: Fixedly connected inside the stirring rod 13, and rotatably connected to the outer surface of the tilting push platform 15. During the movement of the stirring rod 13, the shaft pin 14 plays a crucial connecting and triggering role. When it contacts the triangular limiting block 16, under the constraint of the inclined guide groove 17, the shaft pin 14 tilts at a different angle along the inclined plane, thereby driving the stirring rod 13 to rotate, realizing additional movement of the stirring rod 13 on the basis of its revolution, and providing power for the tumbling of the bottom medicine.

[0037] The tilting and pushing platform 15 is fixedly connected to the inner surface of the mixing tank 11 and consists of an upper ring and a base, providing a rotation track for the shaft pin 14. The triangular limiting block 16 on its outer surface and the inclined guide groove 17 inside cooperate with each other. When the shaft pin 14 contacts the triangular limiting block 16, it guides the shaft pin 14 to move along the inclined guide groove 17, causing the tilting rod 13 to rotate or move axially, thus helping the tilting rod 13 to effectively tilt the medicine at the bottom of the mixing tank 11.

[0038] Triangular limiting block 16: Fixed to the outer surface of the tilting push platform 15, and positioned at the same horizontal level as the shaft pin 14. When the tilting rod 13 revolves, the triangular limiting block 16 collides with the shaft pin 14, using its shape to push the shaft pin 14 along the inclined guide groove 17, thereby triggering the rotation of the tilting rod 13. Simultaneously, the periodic collision of the triangular limiting block 16 can also break up clumps of material. Working in conjunction with the inclined guide groove 17 and the shaft pin 14, it collectively controls the movement of the tilting rod 13 and improves the state of the material.

[0039] Inclined guide groove 17: Formed inside the flipping push table 15, it provides a specific path for the movement of the shaft pin 14. When the shaft pin 14 is pushed by the triangular limiting block 16, it moves along the inclined guide groove 17, causing the shaft pin 14 to change its tilt angle, thereby driving the stirring rod 13 to rotate or move axially, ensuring that the stirring rod 13 can stir the bottom medicine in a predetermined manner. It works in conjunction with the triangular limiting block 16 and the shaft pin 14 to precisely control the movement trajectory of the stirring rod 13.

[0040] Bearing 18: It is sleeved inside the sleeve 12, and the stirring rod 13 is sleeved inside it. It serves to reduce friction, allowing the stirring rod 13 to rotate flexibly within the sleeve 12. This ensures that the stirring rod 13 revolves with the sleeve 12, but does not hinder its rotation or axial movement under specific conditions, thus ensuring the smooth movement of the stirring rod 13 and improving the stirring effect.

[0041] Drive motor 19: Fixed to the upper end of mixing tank 11, it provides power to the entire stirring device. It drives the stirring rod 21 and sleeve 12 to rotate synchronously, and is the power source for basic stirring and a series of subsequent stirring actions. Through the operation of drive motor 19, the stirring rod 21, sleeve 12, stirring rod 13 and other components work together to complete the mixing task of liquid medicine.

[0042] Stirring rod 21: It is sleeved on the outer surface of the drive motor 19 and rotatably connected inside the mixing tank 11, rotating under the drive of the drive motor 19. It performs basic stirring of the liquid agent in the mixing tank 11, stirring the upper liquid to form a horizontal vortex, which works in conjunction with the turning rod 13 to turn the bottom agent, achieving synergistic stirring in both horizontal and vertical directions, and promoting all-round mixing of the liquid agent.

[0043] Funnel-shaped feeding hopper 22: Fixedly connected to the outer surface of mixing tank 11, used to add liquid reagents into mixing tank 11. Its funnel shape facilitates the smooth flow of reagents into mixing tank 11, and the scale strip 23 on the inner surface helps the operator understand the amount of reagent added, achieving preliminary quantitative feeding. In conjunction with the discharge valve 24, the feeding process can be controlled to ensure the appropriate amount of reagent added.

[0044] Scale bar 23: Fixed to the inner surface of the funnel-shaped feeding hopper 22, providing operators with an intuitive reference for the amount of reagent to be added. By observing the scale bar 23, operators can accurately grasp the feeding progress, adjust the feeding speed in a timely manner, or stop feeding, which helps to accurately control the amount of liquid reagent added, ensure the accuracy of the mixing ratio, and thus improve the quality of the mixed reagent.

[0045] Discharge valve 24: Fixed at the lower end of funnel-shaped feed hopper 22 and connected to the outer surface of mixing tank 11. When there is excessive feeding, opening discharge valve 24 can discharge the excess material, avoiding the mixing effect caused by excessive feeding. Together with funnel-shaped feed hopper 22 and scale bar 23, it ensures that the feeding amount meets the mixing requirements and ensures the smooth progress of mixing.

[0046] Discharge valve 25: Fixed inside the mixing tank 11, used to discharge the mixed medicine after the liquid medicine is stirred and mixed evenly in the mixing tank 11 for use. It is a control component for the output of the mixed medicine, realizing the transfer of the mixed medicine from inside the device to the external use stage.

[0047] Control box 26: Fixed on the outer surface of mixing tank 11 and adapted to drive motor 19. By pressing the control button on control box 26, the operator can start or stop drive motor 19, and may also adjust parameters such as speed of drive motor 19, thereby controlling the stirring process and realizing the operation control of the entire stirring device to meet the process requirements of mixing different liquid agents.

[0048] Working principle:

[0049] First, the liquid medicine is added through the funnel-shaped feeding hopper 22. The scale strip 23 on the inner surface of the funnel-shaped feeding hopper 22 can help the operator understand the amount of medicine added. The medicine flows into the mixing tank 11 along the funnel-shaped feeding hopper 22. When there is too much material, the discharge valve 24 at the lower end of the funnel-shaped feeding hopper 22 is opened to discharge the excess material. After the liquid medicine is stirred and mixed evenly in the mixing tank 11, it is discharged through the discharge valve 25 for use.

[0050] Step 2: By pressing the control button on the control box 26, the drive motor 19 is started. The drive motor 19 drives the stirring rod 21 and the sleeve 12 to rotate synchronously, achieving basic stirring. At the same time, the turning rod 13 inside the sleeve 12 moves with the revolution (the turning push table 15 consists of an upper ring and a base, and the shaft pin 14 rotates on the lower surface of the ring). When the shaft pin 14 contacts the triangular limiting block 16 on the turning push table 15, it is constrained by the path of the inclined guide groove 17 and is forced to move along the inclined surface. The change in tilt angle triggers the rotation of the stirring rod 13. As the shaft pin 14 moves periodically along the inclined guide groove 17, the stirring rod 13 rotates or moves axially on the basis of revolution. Its end rotates at the bottom of the mixing tank 11, turning the deposited agent upward. At the same time, the stirring rod 21 continuously stirs the upper liquid, forming vertical convection. The periodic collision of the triangular limiting block 16 further breaks up the clumps of material. Finally, through the synergistic effect of horizontal vortex and vertical stirring, efficient mixing without dead angles is achieved.

[0051] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
