Description

Technical Field

[0001] This utility model belongs to the field of cosmetic processing technology, and in particular relates to a cosmetic raw material mixing tank with heating and heat preservation functions. Background Technology

[0002] In the cosmetics manufacturing industry, the mixing of raw materials is a crucial step. Cosmetic raw materials are diverse, with varying physicochemical properties. Many raw materials (such as oils, waxes, polymers, and active ingredients) are solid or semi-solid at room temperature, or have high viscosity. To achieve a uniform, stable, and high-quality mixing effect, it is often necessary to stir and mix them at specific temperatures. For example, heating can reduce the viscosity of materials, increase their fluidity, and make them easier to mix evenly. At the same time, certain chemical reactions or emulsification processes also require constant temperature conditions to be carried out effectively.

[0003] For example, Chinese patent CN215586096U discloses a cosmetic emulsifying tank with rapid emulsification function, including an outer tank and an emulsifying tank body. The emulsifying tank body is installed inside the outer tank. An emulsifying tank lid is installed on the upper end of the emulsifying tank body. A motor is installed in the middle of the top of the emulsifying tank lid. A feeding port and an observation port are respectively provided on both sides of the motor on the emulsifying tank lid.

[0004] The aforementioned patent utilizes electric heating blocks to heat and stir raw materials, enabling rapid emulsification of cosmetic ingredients and improving production efficiency. However, the direct contact between the electric heating blocks and the emulsification tank body can lead to heat concentration during heating, resulting in uneven heating and heat preservation, which affects the emulsification effect of the cosmetics. Therefore, we propose a cosmetic ingredient mixing tank with heating and heat preservation functions. Summary of the Invention

[0005] The purpose of this invention is to provide a cosmetic raw material mixing container with heating and heat preservation functions to solve the problems mentioned in the background art.

[0006] In view of this, the present invention provides a cosmetic raw material mixing tank with heating and heat preservation function, comprising: a tank body and a controller. The tank body is composed of an insulated outer shell and a mixing inner liner. A heating cavity is provided between the insulated outer shell and the mixing inner liner. Heating tubes arranged at equal intervals are installed inside the heating cavity. A stirring mechanism is installed inside the mixing inner liner. A water inlet valve is fixedly connected to the outer surface of the tank body. One end of the water inlet valve is fixedly connected to a water inlet pipe. A drain valve is fixedly connected to the outer surface of the tank body. One end of the drain valve is fixedly connected to a drain pipe. A top cover is installed at the top of the tank body. A hopper is installed on the upper surface of the top cover. A temperature sensor and a water level sensor connected to the controller are installed inside the heating cavity.

[0007] In the above technical solution, the stirring mechanism further includes a rotating shaft rotatably mounted inside the mixing liner via a bearing and a drive motor mounted on the bottom surface of the tank. The output end of the drive motor is connected to the bottom end of the rotating shaft. Two sets of stirring rods are fixedly connected to the outer surface of the rotating shaft. One end of one set of stirring rods is equipped with a scraper, and the outer surface of each scraper is in contact with the inner wall of the mixing liner.

[0008] In the above technical solution, a cover is installed on the bottom surface of the tank, and heat dissipation holes are opened on the outer surface of the cover. The drive motor is located inside the cover.

[0009] In the above technical solution, the outer surface of the tank is further provided with equidistant material discharge support legs, and each support leg is fixedly connected with a connecting rod on its outer surface, with one end of each connecting rod connected to the outer surface of the tank.

[0010] In the above technical solution, the upper surface of the hopper is provided with a protective cover, the outer surface of the tank is fixedly connected with a discharge valve, the discharge valve is connected to the mixing inner liner, and the upper surface of the top cover is fixedly connected with an exhaust valve, the exhaust valve is connected to the heating cavity.

[0011] In the above technical solution, further, two lifting lugs are fixedly connected to the upper surface of the top cover, a cleaning ring pipe is installed on the bottom surface of the top cover, multiple cleaning nozzles at different angles are installed on the outer surface of the cleaning ring pipe, and a cleaning pipe is fixedly connected to the outer surface of the cleaning ring pipe.

[0012] The beneficial effects of this utility model are: 1. This cosmetic raw material mixing tank with heating and heat preservation functions adopts a unique jacketed structure, forming a heating cavity between the heat preservation shell and the mixing inner liner, and evenly arranging multiple heating tubes in it. This design transforms traditional point or surface contact heating into a surrounding, three-dimensional heat radiation and heat conduction to the entire mixing inner liner, effectively avoiding the problems of local overheating and heat concentration caused by "direct contact of electric heating blocks" mentioned in the background technology. Combined with the feedback and control of temperature sensors, it can achieve precise constant temperature control, ensuring that the materials in the tank are heated evenly. This is crucial for the emulsification and mixing of temperature-sensitive cosmetic raw materials (such as oils and active ingredients), effectively preventing local charring or component deactivation, and significantly improving the uniformity, stability and quality of the final product.

[0013] 2. This cosmetic raw material mixing tank with heating and heat preservation functions is innovative in that its stirring mechanism is equipped with multiple sets of stirring rods to achieve powerful shearing and convection mixing. The scraper is always in contact with the inner wall of the mixing tank. This design can continuously scrape off the high-viscosity material adhering to the inner wall, allowing it to re-participate in the main circulation mixing. This effectively solves the problems of reduced heat transfer efficiency and mixing dead zones caused by adhesion to the inner wall. The cleaning ring pipe at the bottom of the top cover and the cleaning nozzles at multiple angles on it can be connected to the cleaning medium through the cleaning pipe to realize the automated cleaning of the inside of the mixing tank, especially the top cover and the upper part of the side wall.

[0018] Example 1: This example provides a cosmetic raw material mixing tank with heating and heat preservation function, including: tank body 1 and controller 11. The tank body 1 is composed of heat preservation shell 101 and mixing inner liner 102. A heating cavity 103 is provided between the heat preservation shell 101 and the mixing inner liner 102. Heating tubes 19 arranged at equal intervals are installed inside the heating cavity 103. A stirring mechanism 9 is installed inside the mixing inner liner 102. A water inlet valve 8 is fixedly connected to the outer surface of the tank body 1. A water inlet pipe 10 is fixedly connected to one end of the water inlet valve 8. A drain valve 18 is fixedly connected to the outer surface of the tank body 1. A drain pipe 17 is fixedly connected to one end of the drain valve 18. A top cover 2 is installed on the top of the tank body 1. A hopper 4 is installed on the upper surface of the top cover 2. A temperature sensor and a water level sensor connected to the controller 11 are installed inside the heating cavity 103.

[0019] The design employs a unique jacketed structure, forming a heating cavity 103 between the insulated outer shell 101 and the mixing inner liner 102, within which multiple heating tubes 19 are evenly arranged. This design transforms traditional point- or surface-level contact heating into a surrounding, three-dimensional heat radiation and conduction to the entire mixing inner liner 102, effectively avoiding the localized overheating and heat concentration problems caused by "direct contact of heating blocks" mentioned in the background technology. Combined with feedback and control from temperature sensors, precise constant temperature control can be achieved, ensuring uniform heating of the materials inside the container. This is crucial for the emulsification and mixing of temperature-sensitive cosmetic raw materials, effectively preventing localized charring or component deactivation, and significantly improving the uniformity, stability, and quality of the final product.

[0020] Example 2: This example provides a cosmetic raw material mixing tank with heating and heat preservation functions. In addition to the technical solutions of the above examples, it also has the following technical features: the stirring mechanism 9 includes a rotating shaft 901 rotatably mounted inside the mixing liner 102 via bearings and a drive motor 902 mounted on the bottom surface of the tank body 1. The output end of the drive motor 902 is connected to the bottom end of the rotating shaft 901. Two sets of stirring rods 903 are fixedly connected to the outer surface of the rotating shaft 901. One end of one set of stirring rods 903 is equipped with a scraper 904. The outer surface of each scraper 904 is in contact with the inner wall of the mixing liner 102.

[0021] The stirring mechanism 9 is equipped with multiple stirring rods 903 to achieve powerful shearing and convection mixing. A scraper 904 is installed on one of the stirring rods 903, and the scraper 904 is always in contact with the inner wall of the mixing tank 102. This design can continuously scrape off the high-viscosity material adhering to the inner wall, allowing it to re-participate in the main circulation mixing. This effectively solves the problem of reduced heat transfer efficiency and mixing dead corners caused by adhesion to the inner wall, ensuring the consistency of material batches and heat exchange efficiency. It is particularly suitable for processing cosmetic raw materials with high viscosity such as creams and lotions.

[0022] Example 3: This example provides a cosmetic raw material mixing tank with heating and heat preservation functions. In addition to the technical solutions of the above examples, it also has the following technical features: a machine cover 14 is installed on the bottom surface of the tank body 1, and heat dissipation holes 13 are opened on the outer surface of the machine cover 14. The drive motor 902 is located inside the machine cover 14. Support legs 15 with equal-distance material discharge are fixedly connected to the outer surface of the tank body 1. A connecting rod 16 is fixedly connected to the outer surface of each support leg 15. One end of each connecting rod 16 is connected to the outer surface of the tank body 1. A protective cover 5 is provided on the upper surface of the hopper 4. A discharge valve 12 is fixedly connected to the outer surface of the tank body 1. The discharge valve 12 is connected to the mixing inner liner 102. An exhaust valve 3 is fixedly connected to the upper surface of the top cover 2. The exhaust valve 3 is connected to the heating cavity 103.

[0023] The heating cavity 103 itself forms a heat insulation layer, which, together with the heat-insulating shell 101, effectively reduces heat loss to the environment. This structure, combined with precise temperature control, significantly reduces the energy consumption required to maintain the operating temperature, improves thermal energy utilization, and conforms to the concept of green manufacturing. At the same time, the cavity design also facilitates water bath heating through the inlet valve 8 and the drain valve 18, increasing process flexibility. The equipment integrates multiple functions such as heating, heat preservation, efficient mixing, wall scraping, and cleaning. The lifting lug 6 facilitates equipment maintenance and hoisting, the exhaust valve 3 releases pressure inside the cavity to ensure safety, and the cover 14 protects the drive motor 902. The overall design has a high degree of automation, is easy to operate, safe and reliable, and is very suitable for the continuous and standardized operation requirements of modern cosmetic production.

[0024] Example 4: This example provides a cosmetic raw material mixing tank with heating and heat preservation function. In addition to the technical solutions of the above examples, it also has the following technical features: two lifting lugs 6 are fixedly connected to the upper surface of the top cover 2, a cleaning ring pipe 20 is installed on the bottom surface of the top cover 2, a plurality of cleaning nozzles 21 at different angles are installed on the outer surface of the cleaning ring pipe 20, and a cleaning pipe 7 is fixedly connected to the outer surface of the cleaning ring pipe 20.

[0025] The cleaning ring pipe 20 at the bottom of the top cover 2 and the cleaning nozzles 21 at multiple angles constitute the in-situ cleaning (CIP) system. The cleaning medium is connected through the cleaning pipe 7, which can realize the automated cleaning of the inside of the mixing tank 102, especially the top cover 2 and the upper part of the side wall. This greatly reduces the labor intensity of manual cleaning, cleaning dead corners and the risk of cross-contamination, and strictly meets the stringent requirements of cosmetic production for equipment cleanliness.

[0026] Working principle: In use, the mixing tank is first supported in its operating position by the support legs 15. The power supply to the mixing tank is then turned on, and the cosmetic raw materials to be mixed are placed into the mixing liner 102 through the hopper 4. The controller 11, in conjunction with the temperature sensor and water level sensor, causes multiple heating tubes 19 in the heating cavity 103 to heat the water. The good thermal conductivity of the mixing liner 102 is used to heat and keep the raw materials warm. At the same time, the drive motor 902 drives the rotating shaft 901 to rotate. The rotating shaft 901, in conjunction with multiple sets of stirring rods 903, achieves strong shearing and convection mixing. The scraper 904 on the stirring rods 903 can continuously scrape off the high-viscosity materials adhering to the inner wall, allowing them to re-participate in the main circulation mixing. This effectively solves the problem of reduced heat transfer efficiency and mixing dead zones caused by adhesion to the inner wall, ensuring that the materials in the tank are heated evenly.
