Description

Technical Field

[0001] This utility model mainly relates to the field of cosmetic production equipment technology, specifically a large-capacity cosmetic vacuum emulsification device. Background Technology

[0002] Vacuum emulsifying pots are specialized equipment in cosmetic production, primarily used for emulsifying creams and lotions. They are typically equipped with a stirring mechanism, a homogenizing and shearing mechanism, a vacuum system, and a lifting mechanism. The equipment creates a negative pressure environment within a sealed tank, using a homogenizing head to rapidly shear and mix the oil and water phases. Simultaneously, stirring agitates and defoams the materials, reducing internal air bubbles and improving the smoothness of the finished product. Vacuum emulsifying pots enable simultaneous emulsification, mixing, and defoaming, and are widely used in the industrial production of skincare and body wash creams.

[0003] Existing traditional large-capacity vacuum emulsification equipment for cosmetics suffers from several drawbacks in practical use. High-viscosity pastes have poor fluidity, and the high resistance to bubble rise makes it difficult for tiny bubbles deep within the container to rise to the gas-liquid interface on their own. Static degassing using only vacuum negative pressure is ineffective, resulting in low degassing efficiency and a long overall processing cycle. Increasing the stirring speed to enhance degassing can lead to violent slapping of the liquid surface, causing secondary air entrainment and severely impacting the quality of the finished paste. Furthermore, traditional emulsification equipment lacks effective protective structures at the vacuum extraction point, allowing splashing during material stirring and emulsification. This splashed paste can easily enter the vacuum extraction port, causing blockages and contamination of the vacuum lines, affecting the normal operation of the vacuum system. Conventional protective structures also tend to obstruct airflow and hinder gas discharge, interfering with vacuum degassing operations. Overall, the equipment offers poor protection, ease of use, and high maintenance costs. Utility Model Content

[0004] This utility model mainly provides a large-capacity cosmetic vacuum emulsification device to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A large-capacity cosmetic vacuum emulsification device includes a support base and a crossbeam. The top surface of the support base is provided with a placement groove, and an emulsification tank is assembled between the inner walls of the placement groove. The bottom wall of the placement groove is provided with a homogenizing component. Hydraulic lifting components are provided on both sides of the top of the support base; A first drive motor is fixedly installed at the top of the crossbeam, and the output shaft of the first drive motor extends through the crossbeam to a stirring assembly located below it. The stirring assembly includes a drive shaft, a frame-type stirring frame, inclined push blades, a sealing cover, a vacuum extraction port, and an arc-shaped splash plate. The output shaft of the first drive motor extends through the crossbeam and is fixedly connected to the drive shaft below it. The drive shaft extends into the emulsification tank, and the frame-type stirring frame is sleeved on a section of the drive shaft inside the emulsification tank. Multiple inclined push blades are fixedly installed on both the outer and inner walls of the frame-type stirring frame. The upper section of the drive shaft is connected to a sealing cover via a sealed bearing, and a vacuum extraction port is provided on one side of the top of the sealing cover. The vacuum extraction port extends into the emulsification tank and is connected to an arc-shaped splash guard. The vacuum extraction port is located at an off-center position on the sealing cover, and the arc-shaped splash guard is positioned below the opening of the vacuum extraction port facing the inside of the emulsification tank. A gas flow gap is reserved between the arc-shaped splash guard and the vacuum extraction port.

[0006] Preferably, the homogenizing component includes a second drive motor and a homogenizing head. The second drive motor is fixedly installed on the bottom wall of the placement tank, and the output shaft end of the second drive motor passes through the bottom end of the emulsifying tank and the homogenizing head is fixedly installed inside it.

[0007] Preferably, the hydraulic lifting assembly includes a mounting base and a hydraulic push rod. Mounting bases are fixedly installed on both sides of the top of the support base, and hydraulic push rods are fixedly connected to the top of both mounting bases. The actuators of the two hydraulic push rods are respectively fixedly connected to the bottom sides of the crossbeam.

[0008] Preferably, the emulsifying tank has a discharge port on one side of its bottom end.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By applying an upward axial thrust to the material inside the tank through the inclined pusher blades on the frame-type stirring rack, high-viscosity material containing microbubbles deep in the lower part of the tank can be continuously lifted to the gas-liquid interface, improving the problem of high resistance to bubble rise and difficulty in bubble precipitation by buoyancy alone. More material containing bubbles comes into contact with the negative pressure gas phase, causing the microbubbles inside the material to be fully exposed and expand and burst under negative pressure, effectively improving the degassing efficiency of the material inside the large-volume tank, shortening the processing cycle, eliminating the need to increase the stirring speed, avoiding the introduction of new bubbles by high-speed stirring and slapping the liquid surface, and ensuring the processing quality of the finished paste.

[0010] 2. The arc-shaped splash guard can block the upward splashing of paste material during agitation, preventing the paste from directly entering the vacuum extraction port and avoiding contamination and blockage of the external vacuum pipeline. A gas flow gap is maintained between the arc-shaped splash guard and the vacuum extraction port, ensuring that the released gas is not obstructed. This achieves splash protection without interfering with normal vacuum degassing. The overall structure is simple and reliable, and the equipment is easy to maintain. Combined with the hydraulic lifting structure, it facilitates tank loading, feeding, and cleaning, improving the practicality of the equipment.

[0014] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0015] Example Please refer to the appendix carefully. Figure 1-6A large-capacity cosmetic vacuum emulsification device includes a support base 1 and a crossbeam 2. The top surface of the support base 1 is provided with a placement groove 3, and an emulsification tank 4 is assembled between the inner walls of the placement groove 3. The placement groove 3 is used to accommodate and position the emulsification tank 4 to ensure that the emulsification tank 4 remains stable during operation. A discharge port 9 is provided on one side of the bottom end of the emulsification tank 4. The discharge port 9 is used to discharge the processed material out of the tank after the emulsification and defoaming operations are completed. A homogenizing component 5 is provided on the bottom wall of the placement groove 3. The homogenizing component 5 includes a second drive motor 51 and a homogenizing head 52. The second drive motor 51 is fixedly installed on the bottom wall of the placement groove 3. The output shaft end of the second drive motor 51 extends through the bottom end of the emulsification tank 4 into the interior of the emulsification tank 4. The homogenizing head 52 is fixedly installed at the position where the output shaft end of the second drive motor 51 is located inside the emulsification tank 4. When the second drive motor 51 drives the homogenizing head 52 to operate, the homogenizing head 52 performs high-speed shearing emulsification operation on the paste material inside the emulsification tank 4, so that the material particles are refined and evenly dispersed.

[0016] Hydraulic lifting components 6 are provided on both sides of the top of the support base 1. The hydraulic lifting components 6 include mounting bases 61 and hydraulic push rods 62. Mounting bases 61 are fixedly installed on both sides of the top of the support base 1, and hydraulic push rods 62 are fixedly connected to the top of the two mounting bases 61. The actuators of the two hydraulic push rods 62 are fixedly connected to the bottom sides of the crossbeam 2 respectively. When the hydraulic push rods 62 extend, they drive the crossbeam 2 to rise. When the hydraulic push rods 62 retract, they drive the crossbeam 2 to fall.

[0017] A first drive motor 7 is fixedly installed at the top of the crossbeam 2, and the output shaft of the first drive motor 7 extends through the crossbeam 2 to a stirring assembly 8 located below it. The stirring assembly 8 includes a drive shaft 81, a frame-type stirring frame 82, inclined push blades 83, a sealing cover 84, a vacuum extraction port 85, and an arc-shaped splash guard 86. The output shaft of the first drive motor 7 extends through the crossbeam 2 to a location below it, and the output shaft of the first drive motor 7 is fixedly connected to the drive shaft 81. The drive shaft 81 extends into the emulsification tank 4, and a frame-type stirring frame 82 is fitted onto a section of the drive shaft 81 inside the emulsification tank 4. Multiple inclined push blades 83 are fixedly installed on both the outer and inner walls of the frame-type stirring frame 82. After the machine 7 is started, the frame-type stirring frame 82 is driven by the drive shaft 81 to rotate inside the emulsification tank 4. The inclined push blades 83 on the frame-type stirring frame 82 rotate synchronously with the frame-type stirring frame 82. When the inclined push blades 83 rotate, they generate an upward axial thrust on the material at the bottom of the emulsification tank 4, continuously lifting the material containing tiny air bubbles deep in the lower part of the emulsification tank 4 to the gas-liquid interface. Through the forced conveying action of the inclined push blades 83, the air-bubbly material that was originally difficult to float on its own by its own buoyancy is transported to the gas-liquid interface in large quantities. After the material is transported to the gas-liquid interface, the tiny air bubbles inside are fully exposed to the negative pressure gas phase environment, increasing the contact opportunity between the air bubbles and the negative pressure environment.

[0018] A sealing cover 84 is connected to the upper section of the drive shaft 81 via a sealed bearing. The sealing cover 84 rises and falls synchronously with the overall lifting of the drive shaft 81 and the frame-type stirring frame 82. When the sealing cover 84 descends to the opening of the emulsifying tank 4, it closes with the opening of the emulsifying tank 4, achieving a seal inside the emulsifying tank 4. A vacuum extraction port 85 is provided on one side of the top of the sealing cover 84. The vacuum extraction port 85 is located at an eccentric position on the sealing cover 84. An arc-shaped splash plate 86 is connected to one end of the vacuum extraction port 85 extending into the emulsifying tank 4. The arc-shaped splash plate 86 covers the opening of the vacuum extraction port 85 facing the inside of the emulsifying tank 4. A gas flow space is reserved between the arc-shaped splash plate 86 and the vacuum extraction port 85. After the vacuum system is connected to the vacuum extraction port 85, the vacuum system evacuates the interior of the emulsification tank 4 through the vacuum extraction port 85, creating a negative pressure environment inside the emulsification tank 4. Under this negative pressure, air bubbles inside the material reaching the gas-liquid interface expand and burst, causing the bubbles to detach and precipitate from the paste material. The precipitated gas is continuously drawn out of the emulsification tank 4 by the vacuum system through the gas flow gap reserved between the arc-shaped splash plate 86 and the vacuum extraction port 85. When the material is agitated and splashes upwards, it impacts the arc-shaped splash plate 86, preventing the material from directly entering the vacuum extraction port 85. The material blocked by the arc-shaped splash plate 86 falls back into the emulsification tank 4 along the arc surface of the arc-shaped splash plate 86. The arc-shaped splash plate 86 prevents the paste material from entering the external vacuum pipeline, causing pipeline contamination and blockage, while not affecting the normal extraction of gas.

[0019] The specific operation method of this utility model is as follows: During operation, the hydraulic push rod 62 of the hydraulic lifting assembly 6 drives the crossbeam 2 to rise and fall. The crossbeam 2 drives the first drive motor 7, drive shaft 81, and sealing cover 84 to rise or fall as a whole, facilitating the placement of the emulsifying tank 4 in the placement slot 3 of the support base 1 or the removal of the emulsifying tank 4 from the placement slot 3. After the emulsifying tank 4 is in place, the hydraulic push rod 62 drives the crossbeam 2 to descend, causing the sealing cover 84 to close at the opening of the emulsifying tank 4 to achieve internal sealing. The first drive motor 7 is then started, and the first drive motor 7 drives the drive shaft 81 to achieve internal sealing. The frame-type agitator 82 rotates inside the emulsification tank 4. The inclined pusher blades 83 on the frame-type agitator 82 rotate synchronously with the frame-type agitator 82. The inclined pusher blades 83 generate an upward axial thrust on the high-viscosity material at the bottom of the emulsification tank 4, continuously lifting the material containing tiny air bubbles from the lower part of the emulsification tank 4 upward. This allows a large amount of air-bubbly material that would otherwise be difficult to float on its own to be transported to the gas-liquid interface, increasing the contact opportunity between the material and the negative pressure gas phase, and enabling the tiny air bubbles trapped inside the material to be fully exposed. Simultaneously, the second drive motor 51 is activated, driving the homogenizing head 52 to operate. The homogenizing head 52 performs shearing and emulsification operations on the material inside the tank. The vacuum extraction port 85 is connected to an external vacuum system, creating a negative pressure environment inside the emulsification tank 4. Under the negative pressure, the bubbles inside the material reaching the gas-liquid interface expand and burst, causing the bubbles to detach and precipitate from the paste material. The precipitated gas is continuously drawn out of the tank by the vacuum system through the gas flow gap reserved between the arc-shaped splash plate 86 and the vacuum extraction port 85, and the material is agitated. When the material splashes upwards, it will hit the arc-shaped splash plate 86. The arc-shaped splash plate 86 prevents the material from directly entering the vacuum extraction port 85. The blocked material falls back into the emulsification tank 4 along the arc-shaped splash plate 86. This not only prevents the paste material from entering the external vacuum pipeline and causing pipeline contamination and blockage, but also does not affect the normal extraction of gas. This cycle continues to complete the defoaming treatment of the material in the tank. After the emulsification and defoaming operations are completed, the vacuum in the tank is released, and the processed paste material can be discharged out of the tank through the discharge port 9 on one side of the bottom of the emulsification tank 4.
