Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to a well-stirred emulsifying homogenizing reaction vessel. Background Technology

[0002] In the chemical industry, including food, materials, daily necessities, pharmaceuticals, papermaking, and pesticides, homogenizing emulsification reactors are often used to process materials. Due to the high tangential velocity and high-frequency mechanical effect generated by the high-speed rotation of the agitator, the materials are subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing, and turbulence in the narrow gap between the agitator and the stationary mixer, forming suspensions, emulsions, and foams.

[0003] However, in actual use, the above-mentioned emulsification reactor often needs to mix multiple liquids. Due to the different densities of the liquids, the liquid with lower density is prone to be suspended in the upper layer, resulting in inconsistent emulsification between the upper and lower layers of the solution in the reactor. In view of this, we propose an emulsification homogenizing reactor with sufficient stirring. Utility Model Content

[0004] The purpose of this invention is to provide a fully stirred emulsifying homogenizing reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully stirred emulsifying homogenizing reactor, comprising an outer vessel, an inner vessel fixedly connected to the inner wall of the outer vessel, a cover provided on the top end face of the outer vessel, and a mixing assembly provided inside the inner vessel, the mixing assembly comprising:

[0006] The motor is fixedly connected to the top end face of the cover. The output end of the motor is fixedly connected to a rotating shaft. The side wall of the rotating shaft is fixedly connected to a mounting sleeve. The outer wall of the mounting sleeve is fixedly connected to a connecting rod. The end of the connecting rod away from the rotating shaft is fixedly connected to a stirring auger.

[0007] The movable disc has a reciprocating threaded groove on the side wall of the rotating shaft, the movable disc meshes with the reciprocating threaded groove, and a through hole is provided on the top end face of the movable disc.

[0008] Preferably, a liquid injection pipe is fixedly connected to the top end face of the cover, and the bottom end of the liquid injection pipe is located inside the inner vessel, through which liquid can be added to the inner vessel.

[0009] Preferably, a vertical rod is fixedly connected to the bottom end face of the cover, and the vertical rod is sleeved with the movable disc. The vertical rod restricts the mounting sleeve, so that the mounting sleeve can only move longitudinally.

[0010] Preferably, the cross-section of the through hole is trumpet-shaped, and the through hole is provided with a large-diameter end and a small-diameter end, the large-diameter end being located at the top of the movable disk, and the small-diameter end being located at the bottom of the movable disk.

[0011] Preferably, the cross-section of the stirring auger is U-shaped, and there is a gap between the stirring auger and the inner wall of the inner vessel. When the stirring auger rotates, it presses the liquid below the stirring auger downward to prevent the less dense liquid from suspending in the upper layer for a long time.

[0012] Preferably, a connecting frame is fixedly connected to the side wall of the mounting sleeve, and a scraper is fixedly connected to the end of the connecting frame away from the mounting sleeve. The scraper is movably connected to the inner wall of the inner vessel.

[0013] Compared with the prior art, this utility model provides a well-stirred emulsifying homogenizing reactor, which has the following beneficial effects:

[0014] 1. This well-stirred emulsifying homogenizing reactor, through its mixing components and rotating auger, promotes the mixing of various liquids. As the auger rotates, it pushes the liquid below it downwards, preventing less dense liquids from suspending in the upper layer for extended periods. The U-shaped structure accelerates liquid flow, creating a strong vertical circulation that disrupts the layered structure of the liquid, allowing for more thorough contact and mixing between the upper and lower layers. As the moving plate moves downwards, the liquid passes more easily through the through-holes; conversely, as it moves upwards, the liquid finds it more difficult to pass through, thus pushing the liquid upwards. This reduces dead zones or stagnant areas in the mixing zone, ensuring more comprehensive and thorough mixing. Furthermore, it breaks down the static stratification of the liquid, significantly improving mixing efficiency and ensuring uniform liquid distribution.

[0015] 2. This well-stirred emulsifying and homogenizing reactor uses a scraper to scrape the inner wall of the reactor, preventing materials or liquids from depositing on the inner wall due to density differences. Especially during long-term operation, it avoids the phenomenon of low-density materials accumulating on the inner wall while high-density materials settle at the bottom. Attached Figure Description

[0022] like Figures 1-5 As shown, this utility model provides a technical solution: a fully stirred emulsifying homogenizing reactor, including an outer vessel 1, an inner vessel 2 fixedly connected to the inner wall of the outer vessel 1, a cover 3 provided on the top end face of the outer vessel 1, and a mixing component 4 provided inside the inner vessel 2. The mixing component 4 includes a liquid injection pipe 401, a motor 402, a rotating shaft 403, a mounting sleeve 404, a connecting rod 405, a stirring auger 406, a reciprocating threaded groove 407, a movable disc 408, and a through hole 409.

[0023] In one embodiment of this utility model, a liquid injection pipe 401 is fixedly connected to the top end face of the cover 3. The bottom end of the liquid injection pipe 401 is located inside the inner vessel 2. Liquid can be added to the inner vessel 2 through the liquid injection pipe 401. A motor 402 is fixedly connected to the top end face of the cover 3. A rotating shaft 403 is fixedly connected to the output end of the motor 402. An installation sleeve 404 is fixedly connected to the side wall of the rotating shaft 403. A connecting rod 405 is fixedly connected to the outer wall of the installation sleeve 404. A stirring auger 406 is fixedly connected to the end of the connecting rod 405 away from the rotating shaft 403. The cross-section of the stirring auger 406 is U-shaped. There is a gap between the stirring auger 406 and the inner wall of the inner vessel 2. When the stirring auger 406 rotates, the liquid located below the stirring auger 406 is pressed downward to prevent the liquid with lower density from suspending in the upper layer for a long time.

[0024] The side wall of the rotating shaft 403 is provided with a reciprocating threaded groove 407. The movable disk 408 engages with the reciprocating threaded groove 407. A vertical rod 6 is fixedly connected to the bottom end face of the cover 3. The vertical rod 6 is sleeved with the movable disk 408. The vertical rod 6 restricts the mounting sleeve 404, so that the mounting sleeve 404 can only move longitudinally. A through hole 409 is provided on the top end face of the movable disk 408. The cross-section of the through hole 409 is trumpet-shaped. The through hole 409 is provided with a large diameter end and a small diameter end. The large diameter end is located at the top of the movable disk 408, and the small diameter end is located at the bottom of the movable disk 408.

[0025] Motor 402 drives shaft 403 to rotate, which in turn drives mounting sleeve 404 and agitator 406 to rotate. The rotation of agitator 406 promotes the mixing of various liquids. At the same time, since the cross-section of agitator 406 is U-shaped, when agitator 406 rotates, it pushes the liquid below agitator 406 downward, preventing the less dense liquid from suspending in the upper layer for a long time. The U-shaped structure design can accelerate the liquid flow, form a strong vertical circulation, break the layered structure of the liquid, and make the upper and lower layers of liquid more fully contacted and mixed.

[0026] The rotation of the shaft 403 drives the movable disk 408 to move longitudinally. Since the cross-section of the through hole 409 is trumpet-shaped, with the large diameter end located at the top of the movable disk 408 and the small diameter end located at the bottom of the movable disk 408, the liquid can more easily pass through the through hole 409 during the downward movement of the movable disk 408. Then, during the upward movement of the movable disk 408, the liquid has more difficulty passing through the through hole 409, which in turn causes the movable disk 408 to push the liquid upward. This reduces dead corners or stagnant areas of liquid in the stirring area, ensuring more comprehensive and thorough mixing, further breaking the static stratification of the liquid, significantly improving mixing efficiency, and ensuring uniform distribution of the liquid.

[0027] In addition, a connecting frame 7 is fixedly connected to the side wall of the mounting sleeve 404. A scraper 8 is fixedly connected to the end of the connecting frame 7 away from the mounting sleeve 404. The scraper 8 is movably connected to the inner wall of the inner vessel 2. The rotating shaft 403 drives the scraper 8 to rotate. The rotating scraper 8 scrapes the inner wall of the inner vessel 2 to prevent materials or liquids from depositing on the inner wall due to density differences. Especially during long-term operation, it avoids the phenomenon of low-density materials accumulating on the inner wall and high-density materials depositing at the bottom. At the same time, a discharge valve is fixedly installed at the bottom of the outer cylinder, and the discharge valve is connected to the inner cylinder. After the mixing operation is completed, the material is discharged to the outside through the discharge valve.

[0028] In this invention, during use, the motor 402 drives the rotating shaft 403 to rotate, which in turn drives the mounting sleeve 404 and the stirring auger 406 to rotate. The rotation of the stirring auger 406 promotes the mixing of various liquids. When the stirring auger 406 rotates, it presses the liquid below the stirring auger 406 downward, preventing the less dense liquid from suspending in the upper layer for a long time. The rotation of the rotating shaft 403 drives the movable disk 408 to move longitudinally. As the movable disk 408 moves downward, the liquid can more easily pass through the through hole 409. Then, as the movable disk 408 moves upward, the liquid has more difficulty passing through the through hole 409. This causes the movable disk 408 to push the liquid upward, reducing dead corners or stagnant areas in the mixing area, ensuring more comprehensive and thorough mixing, further breaking the static stratification of the liquid, and significantly improving mixing efficiency.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
