Description

Technical Field

[0001] This utility model relates to the field of moisturizing emulsion processing equipment, and in particular to a vacuum mixing device for moisturizing emulsions. Background Technology

[0002] The moisturizing emulsion mixing device ensures that the various components in the moisturizing emulsion are fully integrated through an efficient and uniform mixing process, thereby improving the stability and effectiveness of the product. The moisturizing emulsion can evenly disperse oils, water and various active ingredients in a short time, avoiding stratification or sedimentation, and ensuring that each batch of moisturizing emulsion has consistent quality and excellent moisturizing performance.

[0003] A Chinese patent document CN202322481014.7 discloses a processing reactor for a moisturizing emulsion, comprising a reactor body, a control panel on the right side of the reactor body, a discharge valve on the right side of the reactor body and at the bottom of the control panel, a fixing plate on the left side of the reactor body, a feeding and proportioning component on the fixing plate, a drive motor at the top center of the reactor body, and a rotating shaft extending from the output shaft of the drive motor into the reactor body. Multiple sets of bushings are fitted around the rotating shaft, and cleaning and stirring components are installed on both sides of the middle bushing and on the bottom side of the bottom bushing. In this invention, the structure of the cleaning and stirring components allows for continuous scraping and cleaning of the inner wall and bottom during the internal material stirring process, improving stirring efficiency and preventing material residue on the inner wall and bottom.

[0004] However, the above-mentioned patent has certain defects in use. The inner wall and bottom are continuously scraped and cleaned by a scraper, but if the amount of material added to the reaction vessel during processing is relatively large, the stirring effect is affected by the scraper alone, resulting in uneven mixing of materials and affecting the quality of the final product.

[0005] To address these issues, a vacuum mixing device for moisturizing emulsions is proposed here. Utility Model Content

[0006] To overcome the shortcomings of uneven material mixing in the prior art, this utility model provides a vacuum mixing device for moisturizing emulsions.

[0007] This utility model is achieved using the following technical solution:

[0008] A vacuum mixing device for moisturizing emulsion includes a reaction vessel tank and a detachable top cover. The reaction vessel tank and the top cover form a sealed cavity. A first drive motor is provided on the top of the top cover. A first rotating shaft is provided at the output end of the first drive motor. The first rotating shaft passes through the top cover and moves within the cavity. Multiple connecting arms are evenly arranged along the axial direction at the front end of the first rotating shaft. A scraper that fits against the inner wall of the reaction vessel tank is fixed on the connecting arms.

[0009] A second drive motor is installed at the bottom of the reactor body, and a second rotating shaft is installed at the output end of the second drive motor. The second rotating shaft passes through the reactor body and moves within the cavity. Multiple stirring rods are evenly distributed along the axial direction on the second rotating shaft.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] Example:

[0031] Please see Figures 1-6 A vacuum mixing device for moisturizing emulsion includes a reaction vessel tank 1 and a detachable top cover 2 on the top of the reaction vessel tank 1. The reaction vessel tank 1 and the top cover 2 form a sealed cavity 11. A first drive motor 4 is provided on the top of the top cover 2. A first rotating shaft 41 is provided at the output end of the first drive motor 4. The first rotating shaft 41 passes through the top cover 2 and moves within the cavity 11. A plurality of connecting arms 42 are evenly arranged along the axial direction at the front end of the first rotating shaft 41. A scraper 43 that fits against the inner wall of the reaction vessel tank 1 is fixed on the connecting arms 42.

[0032] The bottom of the reactor vessel 1 is provided with a second drive motor 5, and the output end of the second drive motor 5 is provided with a second rotating shaft 51. The second rotating shaft 51 passes through the reactor vessel 1 and moves within the cavity 11. Multiple stirring rods 52 are evenly distributed along the axial direction on the second rotating shaft 51. The multiple stirring rods 52 are provided with curved guide plates 53, and stirring plates 54 are fixedly provided at the front end of the stirring rods 52.

[0033] In this embodiment, a top cover 2 is provided on the top of the reactor tank 1. The top cover 2 is detachable from the reactor tank 1. When the top cover 2 is installed on the top of the reactor tank 1, the reactor tank 1 and the top cover 2 form a sealed cavity 11. A first drive motor 4 is provided on the top of the top cover 2. A first rotating shaft 41 that can rotate counterclockwise is provided at the output end of the first drive motor 4. The front end of the first rotating shaft 41 passes through the top cover 2 and moves inside the cavity 11. Multiple connecting arms 42 are evenly distributed along the axial direction at the front end of the first rotating shaft 41. A scraper 43 is fixed on the connecting arm 42. The scraper 43 is in close contact with the inner wall of the reactor tank 1. When the first drive motor 4 is started, the scraper 43 rotates with the first rotating shaft 41, effectively removing the residue on the inner wall and pushing it towards the center of the cavity 11, thus preventing the material from accumulating on the inner wall of the reactor tank 1.

[0034] A second drive motor 5 is installed at the bottom of the reactor vessel 1. A second rotating shaft 51, rotatable clockwise, is installed at the output end of the second drive motor 5. The second rotating shaft 51 passes through the vessel and moves within the cavity 11. Multiple stirring rods 52 are evenly distributed axially along the circumferential wall of the second rotating shaft 51. Curved guide plates 53 are installed on the stirring rods 52, and a stirring plate 54 is fixed to the front end of each stirring rod. The stirring plate 54 increases the surface area for stirring the material. When the second drive motor 5 starts, it rotates clockwise, causing the guide plates 53 and stirring plates 54 on the stirring rods 52 to rotate synchronously, forming a vortex. The scraper 43 operates independently of the guide plates 53 and stirring plates 54. The scraper 43 scrapes away material from the inner wall of the reactor vessel 1 and brings it towards the center of the cavity 11. The guide plates 53 and stirring plates 54 then promote uniform mixing of the material, improving reaction efficiency and ensuring sufficient reaction within the cavity 11.

[0035] Specifically, a vacuum pump 21 is provided on the top of the top cover 2, and a pressure pumping pipe 22 for pumping air pressure inside the cavity 11 is connected to the vacuum pump 21.

[0036] In this embodiment, a vacuum pump 21 is provided on the top of the top cover 2, and a pressure suction pipe 22 is provided at the output end of the vacuum pump 21. The pressure suction pipe 22 passes through the top cover 2 and is connected to the cavity 11. The vacuum pump 21 extracts gas from the cavity 11 through the pressure suction pipe 22 to form a negative pressure environment, prevent the material from oxidizing, and ensure the purity of the material during processing.

[0037] The top of the top cover 2 is also provided with a feed pipe 23. The feed pipe 23 is provided with a feed valve 24 to control the opening and closing of the feed pipe 23. When the feed valve 24 is opened, the processed material enters the cavity 11 from the feed pipe 23. Before starting work, the feed valve 24 is closed to ensure that the cavity 11 is in a sealed state.

[0038] Specifically, the bottom of the reactor tank 1 is provided with a discharge port 6, and the inner bottom wall of the reactor tank 1 is inclined towards the discharge port 6. The discharge port 6 is connected to a discharge pipe 61, and a discharge valve 62 is provided on the discharge pipe 61 to control the opening and closing of the discharge pipe 61.

[0039] In this embodiment, the bottom of the reactor tank 1 is provided with a discharge port 6, and the inner bottom wall of the reactor tank 1 is inclined towards the discharge port 6 to facilitate the smooth flow of materials to the discharge port 6 under the action of gravity. A discharge pipe 61 is connected at the discharge port, and a discharge valve 62 is provided on the discharge pipe 61. By controlling the opening and closing of the discharge valve 62, the precise discharge of materials can be achieved.

[0040] Specifically, a central controller 12 is provided on the outer peripheral wall of the reaction vessel 1.

[0041] In this embodiment, a central controller 12 is provided on the outer peripheral wall of the reactor tank 1. The central controller 12 can control the coordinated operation of the first motor, the second motor, the vacuum pump 21, the feed valve 24 and the discharge valve 62 to realize a fully automated material handling process and improve production efficiency.

[0042] Specifically, the top cover 2 is provided with handles 25 on both sides of the top, and the top cover 2 and the reactor body 1 are provided with connection holes 3. The connection holes 3 are provided with bolts 31 for detachably connecting the top cover 2 and the reactor body 1.

[0043] In this embodiment, handles 25 are provided on both sides of the upper surface of the top cover 2 to facilitate the operator to carry and open the top cover 2. Multiple connection holes 3 are provided at the top of the reactor body 1 and the upper wall of the top cover 2. Bolts 31 are provided in the even number of connection holes 3. The top cover 2 is detachably connected to the top of the reactor body 1 by bolts 31 to ensure that the top cover 2 fits tightly with the tank body and prevent gas leakage from the cavity 11.

[0044] Specifically, the bottom peripheral wall of the reactor vessel 1 is provided with multiple support legs 7.

[0045] In this embodiment, the bottom of the reactor vessel 1 is provided with multiple support legs 7 to support the reactor vessel 1 to stand stably.

[0046] Specifically, the scraper 43 is provided with multiple flow holes 44 in the horizontal direction, and an elastic buffer pad 8 is provided at the front end of the scraper 43 where it is in contact with the reaction vessel 1.

[0047] In this embodiment, the scraper 43 has multiple flow holes 44 horizontally penetrating its surface. When the scraper 43 is moving, the flow holes 44 are provided to reduce the frictional resistance between the material and the scraper 43, so that the material flows smoothly under the action of the scraper 43, reducing the load on the first rotating shaft 41 and the connecting arm 42. An elastic buffer pad 8 is provided at the front end of the scraper 43. The elastic buffer pad 8 is made of soft rubber. When the scraper 43 comes into contact with the inner wall of the tank, the elastic buffer pad 8 protects the inner wall of the reactor tank 1 from damage.

[0048] Specifically, the bending direction of the guide plate 53 is tangent to the rotation direction of the first rotating shaft 41.

[0049] In this embodiment, the bending direction of the guide plate 53 is tangential to the rotation direction of the first rotating shaft 41, which can reduce the resistance of the second rotating shaft 51 and the stirring rod 52 during the stirring process while stirring, ensuring that the material flows smoothly along the guide plate 53 during the rotation process and improving the stirring efficiency.

[0050] The principle of this utility model is as follows: when the feed valve 24 is opened, the material is injected into the cavity 11 through the feed pipe 23. The vacuum pump 21 draws air from the cavity 11 through the suction pipe 22 to form a negative pressure to prevent the material from oxidizing. The first drive motor 4 drives the first rotating shaft 41 to rotate counterclockwise, which drives the scraper 43 to scrape off the material on the inner wall of the reactor tank 1 and push it towards the center of the cavity 11. At the same time, the second drive motor 5 drives the second rotating shaft 51 to rotate clockwise, which drives the stirring rod 52, the guide plate 53 and the stirring plate 54 to rotate. The first rotating shaft 41 rotates to the tangent guide plate 53 to guide the material to form a vortex, which is convectively mixed with the material pushed by the scraper 43, ensuring that the material in the cavity 11 is uniformly mixed.

[0051] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
