Description

Technical Field

[0001] This application relates to the field of pharmaceutical raw material emulsification processing technology, and in particular to an emulsification stirring device. Background Technology

[0002] Emulsification is the phenomenon of a liquid being uniformly dispersed in extremely small droplets within another immiscible liquid. Emulsification is a liquid-liquid interface phenomenon; two immiscible liquids, such as oil and water, separate into two layers in a container, with the less dense oil on top and the denser water on the bottom. If a suitable surfactant is added and vigorous stirring is applied, the oil is dispersed in the water to form an emulsion; this process is called emulsification.

[0003] Existing technologies typically employ emulsification within a mixing tank. Chinese Patent Application No. CN202322431645.8 discloses a high-shear emulsifier: It includes a mixing drum with a discharge port at its lower end; a mounting base disposed at one end of the mixing drum, with an inner cavity at one end, and the other end of the mounting base penetrating the mixing drum and located inside the drum; an inner magnetic tile rotatably disposed within the inner cavity; a first driving component disposed near the inner cavity end of the mounting base, used to drive the inner magnetic tile to rotate; an outer magnetic base rotatably disposed on the mounting base, and having blades on it; the outer magnetic tile disposed on the outer magnetic base; and a stator cover disposed on the mounting base, forming an emulsification cavity between the stator cover and the outer magnetic base. This technical solution solves the problem of poor sealing reliability in existing high-shear emulsifiers.

[0004] This emulsifier improves emulsification by installing a high-shear emulsifier drive unit at the bottom of the mixing drum. However, the stator cover and impeller, which perform shear emulsification, are positioned at a fixed height within the mixing drum. This limits the emulsification effect to pharmaceutical raw materials located in a fixed position within the drum, resulting in a limited efficiency and impacting the overall effectiveness of the device. Therefore, improvements are needed. Utility Model Content

[0005] To improve the uniformity of pharmaceutical raw material emulsification, this application provides an emulsification stirring device.

[0006] The emulsification and stirring device provided in this application adopts the following technical solution:

[0007] An emulsifying and stirring device includes a stirring drum; a shearing structure is installed on the stirring drum, the shearing structure includes a mounting plate, the mounting plate is installed on the lower side of the stirring drum, a guide rod is fixedly connected to the top surface of the mounting plate, a limit cylinder and an electric telescopic rod are fixedly installed on the outer wall of the stirring drum, a motor is fixedly installed on the top surface of the mounting plate, a paddle rod is fixedly connected to the output end of the motor, a fixing plate is fixedly installed on the top surface of the mounting plate, a piston sleeve is sleeved on the outer wall of the fixing plate, and a stator cover is fixedly connected to the top surface of the fixing plate.

[0008] By adopting the above technical solution, when it is necessary to adjust the positions of the paddle rod and the stator cover inside the mixing drum, start the electric telescopic rod to drive the mounting plate to rise, and the mounting plate drives the guide rod to slide inside the limiting cylinder; the guide rod cooperates with the limiting cylinder to guide and limit the movement of the mounting plate, so that the mounting plate can move vertically in a straight line, so that the upper ends of the paddle rod and the stator cover move up and down inside the mixing drum. Adjust the position of shearing and emulsifying the materials in the mixing drum to expand the range of shearing and emulsifying, and then improve the emulsification uniformity of the materials.

[0009] Optionally, a stirring structure is installed on the mixing drum. The stirring structure includes a motor. The motor is fixedly installed on the top surface of the mixing drum. The output end of the motor is fixedly connected with a stirring paddle. A fixing frame is fixedly installed inside the mixing drum. A bearing sleeve is fixedly installed in the middle of the fixing frame. The bottom end of the stirring paddle is fixedly connected with an inclined plate, and through grooves are formed on the surface of the inclined plate.

[0010] Optionally, the guide rod is in a "zhong" - shaped structure. The guide rod is slidably installed inside the limiting cylinder, and the extending end of the electric telescopic rod is fixedly connected with the mounting plate.

[0011] By adopting the above technical solution, starting the motor can drive the stirring paddle to rotate. The rotation of the stirring paddle can agitate the materials inside the mixing drum. The fixing frame is fixedly installed inside the mixing drum. During use, it can destroy the eddy current formed by the rotation of the stirring paddle. The bottom end of the stirring paddle is rotatably connected with the fixing frame through a bearing sleeve. The bearing sleeve can limit the stirring paddle at the lower side, making the stirring paddle rotate stably inside the mixing drum.

[0013] Optionally, the outer wall of the piston sleeve is in close fit with the inner wall of the activity groove.

[0014] By adopting the above technical solution, when the mounting plate moves, it can drive the fixing plate to move inside the activity groove. The piston sleeve can ensure the sealing between the fixing plate and the inner wall of the activity groove, and can separate the upper and lower parts of the fixing plate, so as to avoid the leakage of the materials inside the mixing drum downward through the gap between the activity groove and the fixing plate.

[0015] Optionally, the upper end of the stator cover is located outside the upper end of the paddle rod.

[0016] Optionally, the lower end of the stirring paddle is rotatably connected with the fixing frame through a bearing sleeve, and the inclined plate is installed in an inclined manner.

[0017] Optionally, the length direction of the through groove has an angle with the section plane of the inclined plate.

[0018] By adopting the above technical solution, the rotation of the stirring paddle can drive the rotation of the inclined plate. When the inclined plate rotates, it can push the material, so that some of the material flows through the channel in the inclined plate, which can disperse the material and further improve the emulsification effect of the material.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. When it is necessary to adjust the position of the paddle and stator cover inside the mixing drum, activate the electric telescopic rod. The electric telescopic rod can drive the mounting plate to rise, and the mounting plate can drive the guide rod to slide within the limiting cylinder. The guide rod, in conjunction with the limiting cylinder, can guide and limit the movement of the mounting plate, allowing the mounting plate to move vertically up and down, so that the upper ends of the paddle and stator cover can move up and down inside the mixing drum. The vertically movable mounting plate drives the paddle and stator cover to move up and down within the movable groove, adjusting the position of the material shearing and emulsification within the mixing drum, expanding the range of shearing and emulsification, and thus improving the uniformity of material emulsification.

[0021] 2. When the mounting plate moves, it can drive the fixed plate to move in the movable groove. The piston sleeve can ensure the sealing between the fixed plate and the inner wall of the movable groove, and can separate the upper and lower parts of the fixed plate to prevent the material in the mixing drum from leaking downward through the gap between the movable groove and the fixed plate.

[0022] 3. By setting up a stirring structure, the motor is started to drive the stirring paddle to rotate. The rotation of the stirring paddle can agitate the material inside the stirring drum. The fixed frame is fixedly installed inside the stirring drum. During use, it can break the eddy current formed by the rotation of the stirring paddle. The bottom end of the stirring paddle is rotatably connected to the fixed frame through a bearing sleeve. The bearing sleeve can limit the stirring paddle from the bottom, so that the stirring paddle rotates stably inside the stirring drum. The rotation of the stirring paddle drives the rotation of the inclined plate. When the inclined plate rotates, it can push the material, so that some of the material flows through the channel in the inclined plate and disperses the material, which can further improve the emulsification effect of the material.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses an emulsifying and stirring apparatus. (Refer to...) Figure 1 and Figure 2 An emulsifying and mixing device includes a mixing drum 1, with a movable groove 11 on the bottom surface of the mixing drum 1. A shearing structure 2 is installed on the mixing drum 1. The shearing structure 2 includes a mounting plate 21, which is installed on the lower side of the mixing drum 1. A guide rod 22 is fixedly connected to the top surface of the mounting plate 21. A limit cylinder 23 and an electric telescopic rod 24 are fixedly installed on the outer wall of the mixing drum 1. A motor 25 is fixedly installed on the top surface of the mounting plate 21, and a paddle rod 26 is fixedly connected to the output end of the motor 25. A fixing plate 27 is fixedly installed on the top surface of the mounting plate 21. A piston sleeve 28 is fitted on the outer wall of the fixing plate 27, and a stator cover 29 is fixedly connected to the top surface of the fixing plate 27.

[0031] When it is necessary to adjust the position of the paddle 26 and stator cover 29 inside the mixing drum 1, the electric telescopic rod 24 is activated. The electric telescopic rod 24 drives the mounting plate 21 to rise, and the mounting plate 21 drives the guide rod 22 to slide within the limiting cylinder 23. The guide rod 22, in conjunction with the limiting cylinder 23, guides and limits the movement of the mounting plate 21, allowing the mounting plate 21 to move vertically, so that the upper ends of the paddle 26 and stator cover 29 can move up and down within the mixing drum 1. The mounting plate 21 can move up and down, driving the paddle 26 and stator cover 29 to move up and down within the movable groove 11, adjusting the position of the material shearing and emulsification within the mixing drum 1, expanding the range of shearing and emulsification, and thus improving the uniformity of material emulsification.

[0032] Reference Figure 2 and Figure 4, a stirring structure 3 is installed on the mixing drum 1. The stirring structure 3 includes a motor 31. The motor 31 is fixedly installed on the top surface of the mixing drum 1. The output end of the motor 31 is fixedly connected with a stirring paddle 32. A fixing frame 33 is fixedly installed inside the mixing drum 1. A bearing sleeve 34 is fixedly installed in the middle of the fixing frame 33. The bottom end of the stirring paddle 32 is fixedly connected with an inclined plate 35. Through grooves 36 are formed on the surface of the inclined plate 35. When the inclined plate 35 rotates, it can push the materials, enabling some materials to flow inside the inclined plate 35 through the through grooves 36, dispersing the materials, and further improving the emulsification effect on the materials.

[0033] The lower end of the stirring paddle 32 is rotatably connected to the fixing frame 33 through the bearing sleeve 34. The inclined plate 35 is installed in an inclined manner. The bearing sleeve 34 and the fixing frame 33 cooperate to limit the rotation of the stirring paddle 32 at the lower side. When the inclined plate 35 rotates, it can squeeze the materials downward, enabling the materials to move upward along the inner edge of the mixing drum 1, thereby improving the surging effect of the materials inside the mixing drum 1. The length direction of the through grooves 36 has an angle with the section plane of the inclined plate 35, ensuring that the materials flow inside the inclined plate 35 through the through grooves 36, dispersing the materials, and further improving the emulsification effect on the materials.

[0034] Refer to Figure 3 and Figure 5 , the guide rod 22 is in a "middle" - shaped structure. The guide rod 22 is slidably installed inside the limiting cylinder 23. The extending end of the electric telescopic rod 24 is fixedly connected to the mounting plate 21. The guide rod 22 and the limiting cylinder 23 cooperate to provide guiding and limiting for the movement of the mounting plate 21, and the electric telescopic rod 24 provides power for the movement of the mounting plate 21.

[0035] The paddle rod 26 penetrates through the fixing plate 27. A rotary seal ring is arranged at the connection between the paddle rod 26 and the fixing plate 27. The fixing plate 27 is located inside the activity groove 11. The motor 25 provides power for the rotation of the paddle rod 26. The setting of the rotary seal ring can ensure the sealing performance at the connection between the paddle rod 26 and the fixing plate 27, and materials will not leak downward from the connection between the paddle rod 26 and the fixing plate 27. When the fixing plate 27 moves inside the activity groove 11, it can carry the materials to move inside the activity groove 11.

[0036] The outer wall of the piston sleeve 28 is in close fit with the inner wall of the activity groove 11. The piston sleeve 28 can ensure the seal between the fixing plate 27 and the activity groove 11, preventing materials from leaking downward between the fixing plate 27 and the activity groove 11.

[0037] Refer to Figure 5 , the upper end of the stator cover 29 is located outside the upper end of the paddle rod 26. The rotation of the paddle rod 26 can continuously suck the materials into the stator cover 29. There is a gap between the paddle rod 26 and the stator cover 29. During the high - speed rotation of the paddle rod 26, the materials are dispersed and emulsified. At the same time, the newly sucked materials into the stator cover 29 will extrude the dispersed and emulsified materials. This process repeats until the materials are emulsified evenly.

[0038] The implementation principle of the emulsifying and stirring device in this application embodiment is as follows: When in use, the motor 25 is started, which drives the paddle 26 to rotate. The paddle 26 rotates inside the stator cover 29, which can continuously suck the material into the stator cover 29. There is a gap between the paddle 26 and the stator cover 29. The material is dispersed and emulsified during the high-speed rotation of the paddle 26. At the same time, the newly sucked material into the stator cover 29 will squeeze out the dispersed and emulsified material. This cycle repeats until the material is emulsified evenly.

[0039] When it is necessary to adjust the position of the paddle 26 and stator cover 29 inside the mixing drum 1, the electric telescopic rod 24 is activated. The electric telescopic rod 24 can drive the mounting plate 21 to rise, and the mounting plate 21 drives the guide rod 22 to slide within the limiting cylinder 23. The guide rod 22, in conjunction with the limiting cylinder 23, can guide and limit the movement of the mounting plate 21, allowing the mounting plate 21 to move up and down in the vertical direction. This allows the upper ends of the paddle 26 and stator cover 29 to move up and down within the mixing drum 1, adjusting the position for shearing and emulsifying the material inside the mixing drum 1, thereby expanding the range of shearing and emulsification and improving the uniformity of emulsification of the material.

[0040] When the mounting plate 21 moves, it can drive the fixed plate 27 to move in the movable groove 11. The setting of the piston sleeve 28 can ensure the sealing between the fixed plate 27 and the inner wall of the movable groove 11, and can separate the upper and lower parts of the fixed plate 27 to prevent the material in the mixing drum 1 from leaking downward through the gap between the movable groove 11 and the fixed plate 27.

[0041] The motor 31 is started, which drives the stirring paddle 32 to rotate. The rotation of the stirring paddle 32 can agitate the material inside the mixing drum 1. The fixing frame 33 is fixedly installed inside the mixing drum 1. During use, it can break the eddy current formed by the rotation of the stirring paddle 32, thereby improving the emulsification effect. The bottom end of the stirring paddle 32 is rotatably connected to the fixing frame 33 through the bearing sleeve 34. The bearing sleeve 34 can limit the stirring paddle 32 from the bottom, so that the stirring paddle 32 rotates stably inside the mixing drum 1. The rotation of the stirring paddle 32 can drive the rotation of the inclined plate 35. When the inclined plate 35 rotates, it can push the material, so that some of the material flows through the channel 36 in the inclined plate 35, which can disperse the material and further improve the emulsification effect of the material.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
