Abstract
Description
Technical Field
[0001] This application relates to the field of mixing equipment, and in particular to a cinnamaldehyde self-emulsifying vacuum mixing device. Background Technology
[0002] In the self-emulsification production process of cinnamaldehyde, traditional stirring equipment has significant technical defects: First, the stirring structure is simple, mostly using single-layer blades, which can only stir the local materials in the tank. This easily leads to problems such as insufficient dispersion of the upper layer materials, weak convection of the middle layer materials, and deposition and agglomeration of the lower layer materials and tank walls. As a result, the uniformity of mixing between cinnamaldehyde and emulsifying additives is insufficient, which directly affects the stability of the self-emulsification system. Subsequent re-stirring is required, reducing production efficiency. Second, the sealing performance is poor. Most equipment cannot achieve a stable vacuum environment. During the stirring process, air is easily mixed into the material to form bubbles. This not only damages the microstructure of the self-emulsification system, but may also cause cinnamaldehyde to undergo an oxidation reaction with oxygen in the air, reducing the purity and quality of the product.

[0014] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0015] This application discloses a cinnamaldehyde self-emulsifying vacuum stirring device, referring to... Figure 1 It includes a mixing tank 1, which is a cylindrical sealed cavity made of 304 stainless steel with a smooth inner wall and no dead corners. It is used to contain cinnamaldehyde and other materials to be emulsified, ensuring the sealing and safety of the material mixing process.
[0016] Reference Figures 1-3 The stirring mechanism is installed inside the stirring tank 1 via a drive mechanism to achieve all-round stirring of materials, specifically including: The rotating rod 8 is vertically inserted at the center of the top surface of the mixing tank 1 and cooperates with the sealing bearing on the top surface of the mixing tank 1. It can rotate around its own axis and maintain the seal inside the tank. The serrated dispersion disc 17, the collar 18, and the ribbon blade 21 are fixedly sleeved from top to bottom along the vertical direction of the rotating rod 8. The serrated dispersion disc 17 has 45° inclined serrations and is used to shear and disperse the upper layer of material. The pitch of the ribbon blade 21 is 1.8 times the diameter of the rotating rod 8, and the gap between the edge and the inner wall of the mixing tank 1 is 8mm. It is used to stir the lower layer and the material near the tank wall to prevent sedimentation. The frame blade 19 is symmetrically fixed on the outer wall of the collar 18 and has a gap of 10mm between it and the inner wall of the mixing tank 1. It is used to stir the middle layer of material. The through holes 20 are evenly opened on the two frame blades 19 and are multiple in number. They can reduce the resistance of the material to the blades and enhance the material convection.
[0017] The drive mechanism, used to drive the stirring mechanism to rotate and move up and down to achieve three-dimensional stirring, specifically includes: a support 11 fixed to one end of the top surface of the stirring tank 1, which is a steel frame structure providing support for component installation; a threaded rod 13 and a guide rod 14, which are installed horizontally and vertically inside the support 11; the threaded rod 13 is located at the end away from the rotating rod 8 and is rotatable by cooperating with the bearings at the upper and lower ends of the support 11; the guide rod 14 is located at the end closer to the rotating rod 8 and is rotatably connected by cooperating with the bearings at the upper and lower ends of the support 11, serving a guiding function; and third pulleys 22, which are respectively fixedly sleeved on the bottom ends of the threaded rod 13 and the guide rod 14. The two third pulleys 22 are connected by synchronous belts. A belt drive connection enables synchronous movement of the threaded rod 13 and the guide rod 14. The motor 12 is fixed on the top surface of the bracket 11 and is a servo motor. Its output end is connected to the top of the threaded rod 13 through a coupling to provide power to the drive mechanism. The second pulley 16 is sleeved on the outer wall of the guide rod 14 through a sleeve. The retaining strip on the outer wall of the guide rod 14 is located in the retaining groove inside the sleeve, so that the second pulley 16 can rotate synchronously with the guide rod 14. At the same time, the retaining strip and the retaining groove are set so that when the moving plate 10 moves up and down along the threaded rod 13, the moving plate 10 can drive the second pulley 16 to move up and down along the vertical direction of the retaining strip on the guide rod 14 while rotating.
[0018] The movable plate 10 is threaded onto the outer wall of the threaded rod 13 at one end and fixedly connected to the top of the rotating rod 8 at the other end, and slidably engaged with the guide rod 14. The movable plate 10 is located on the bottom surface of the second pulley 16 and moves up and down along the guide rod 14 as the threaded rod 13 rotates. At the same time, the bottom end of the sleeve is rotatably connected to the movable plate 10. The first pulley 9 is fixedly mounted on the top of the rotating rod 8 and located above the movable plate 10. It is connected to the second pulley 16 through a synchronous belt drive, so that the rotating rod 8 rotates synchronously with the second pulley 16. In conjunction with the stirring mechanism, it realizes a three-dimensional stirring mode of shear dispersion, radial convection, and axial circulation, which greatly improves the stirring efficiency and completely solves the problems of insufficient material dispersion and sedimentation in traditional equipment.
[0019] Reference Figure 1 It also includes: a vacuum pump 7, which is a rotary vane vacuum pump, connected to the top surface of the mixing tank 1 through a pipe; a vacuum valve installed on the pipe between the vacuum pump 7 and the mixing tank 1, which is a solenoid valve used to control the opening and closing of the vacuum pipe; a pressure sensor 6 fixed on the top surface of the mixing tank 1, with the detection end extending downward to the middle of the tank; the pressure sensor 6 is electrically connected to the control system; when the pressure inside the tank exceeds the set range, the control system automatically starts or stops the vacuum pump 7 or adjusts the vacuum valve to achieve automatic control of the vacuum level.
[0020] It also includes: a feed pipe 15 fixed to the top outer wall of the mixing tank 1 to facilitate the addition of materials, and a discharge pipe 2 fixed to the bottom outer wall of the mixing tank 1 to facilitate the complete discharge of materials.
[0021] The solenoid valves are installed on the feed pipe 15 and the discharge pipe 2 respectively. They are normally closed and their on / off state is controlled by the control system to ensure the tank is sealed.
[0022] There are four fixed frames 4, made of angle steel, which are fixed in a circular shape at equal intervals to the bottom edge of the mixing tank 1 and welded to the tank wall. There are four support legs 3, which are fixed to the bottom surface of each fixed frame 4. An observation window made of tempered glass is set on the top surface of the mixing tank 1 to facilitate observation of the mixing state of the materials inside the tank.
[0023] The implementation principle of the cinnamaldehyde self-emulsifying vacuum mixing device in this application embodiment is as follows: During use, the solenoid valve on the feed pipe 15 is opened by the control system, and cinnamaldehyde and other auxiliary materials are added into the mixing tank 1 through the feed pipe 15. The solenoid valve is then closed. The vacuum pump 7 is started, the vacuum valve is opened, and the air in the tank is extracted. The pressure sensor 6 monitors the pressure in the tank in real time. When the set vacuum degree is reached, the control system closes the vacuum pump 7 and the vacuum valve, and starts the motor 12. The motor 12 drives the threaded rod 13 to rotate. Through the third pulley 22 and the synchronous belt, the guide rod 14 rotates synchronously. The rotation of the threaded rod 13 drives the moving plate 10 to move up and down along the guide rod 14. At the same time, the second pulley 16 on the guide rod 14 drives the first pulley 9 to rotate through the synchronous belt, so that the rotating rod 8 and the multi-layer blades rotate at high speed. During this stage, the serrated dispersion disc 17 generates strong shearing force, dispersing the cinnamaldehyde agglomerates into tiny droplets. The frame-type paddle 19 pushes the middle layer material to form radial convection, and the through hole 20 promotes axial turbulence of the material, accelerating the mixing of the dispersed cinnamaldehyde droplets. The ribbon-type paddle 21 conveys the material at the bottom of the tank upwards, preventing cinnamaldehyde from settling at the bottom of the tank due to its high density. During the stirring process, pressure sensor 6 monitors the pressure inside the tank in real time. When the pressure is affected by material evaporation or slight leakage, the control system automatically starts vacuum pump 7 to pump the pressure back to a safe range and then shuts it off, ensuring that the entire stirring process is carried out in a stable vacuum environment and avoiding air mixing that could cause the emulsion system to break down.
