Description

After stirring, heating, and cooling within the tank, the semi-finished material is then transported to a semi-finished product storage tank via a rotary pump. After standing for a period of time, it is packaged. However, for cosmetic materials with a viscosity greater than 0.5 million cps, after the rotary pump completes the discharge process, a significant amount of material often remains on the tank walls and stirring mechanism due to its high viscosity, resulting in substantial waste.

[0024] Reference Figure 1The discharge system of the cosmetic emulsification tank provided in the embodiments of the present invention includes an emulsification tank 100, a rotor pump 200, a material storage device 300, and a control device. The emulsification tank 100, the rotor pump 200, and the material storage device 300 are connected in sequence. A stirring mechanism 400 is provided inside the emulsification tank 100. A scraper 430 for scraping residual material on the inner wall of the emulsification tank 100 is installed on the stirring mechanism 400. A stirring drive for driving the stirring mechanism 400 to rotate is installed in the emulsification tank 100. The stirring drive device 500 and the emulsifying tank 100 are equipped with a weighing module 600 for weighing the material inside the emulsifying tank 100. The stirring drive device 500, the rotor pump 200, and the weighing module 600 are all electrically connected to the control device. During the process of the rotor pump 200 conveying the material from the emulsifying tank 100 to the material storage device 300, the control device obtains the weight w0 of the material inside the emulsifying tank 100 through the weighing module 600. When the material weight w0 is less than the set stirring discharge start weight w... j The control device controls the stirring drive device 500 to drive the stirring mechanism 400 to rotate.

[0025] The discharge system of the cosmetic emulsifying tank provided by this invention allows the control device to obtain the weight w0 of the material in the emulsifying tank 100 through the weighing module 600 during the process of the rotor pump 200 conveying the material in the emulsifying tank 100 to the material storage device 300. When the material weight w0 is less than the set stirring and discharge start weight w0, the system can discharge the material. j The control device controls the stirring drive device 500 to drive the stirring mechanism 400 to rotate, thereby using the scraper 430 on the stirring mechanism 400 to scrape off the residue on the inner wall of the emulsification tank 100, and at the same time throw off the residual material on the stirring mechanism 400. This can reduce the material residue in the emulsification tank 100 after the material is discharged, reduce material loss, and control costs.

[0026] In some embodiments, the rated capacity of the emulsifying tank can be 1000 liters. Since the density of cosmetics is similar to that of water, the emulsifying tank 100 can hold approximately 1000 kg of material. With existing discharge methods, 30 to 40 kg of material typically remains in the stirring mechanism 400 or on the inner wall of the emulsifying tank 100. However, the discharge system provided by this invention saves 20 to 40 kg of semi-finished material for every 1000 kg of material produced by the emulsifying tank 100, achieving the goals of loss reduction, energy saving, and intelligent manufacturing.

[0027] Of course, it should be noted that in the specific implementation process, the rated capacity of the emulsifying tank can be greater than 1000 liters, for example, the rated capacity of the emulsifying tank is 1500 liters, and the rated capacity of the emulsifying tank can also be less than 1000 liters, for example, the rated capacity of the emulsifying tank is 800 liters.

[0028] In the prior art, during the discharge process, the rotor pump 200 usually operates at high speed to ensure high discharge efficiency of the emulsification tank 100. However, when the material height in the emulsification tank 100 is small, due to the high viscosity and poor flowability of the material, a vortex will form at the discharge port at the bottom of the emulsification tank 100. This causes a large amount of gas in the emulsification tank 100 to enter the rotor pump 200, forming a large number of bubbles in the material. This affects the net content and appearance of the product during filling and can easily cause serious cavitation damage to the rotor pump 200.

[0029] According to some embodiments of the present invention, the discharge system has a first discharge mode and a second discharge mode. The control device is set with operating parameters for the first discharge mode and the second discharge mode. The operating parameters of the first discharge mode include at least a first rotational speed n1 of the rotor pump 200, and the operating parameters of the second discharge mode include at least a second rotational speed n2 of the rotor pump 200 and a first starting weight w1, wherein the second rotational speed n2 is less than the first rotational speed n1. During the discharge process of the emulsion tank 100, if the material weight w0 measured by the weighing module 600 is greater than w1, the discharge system enters the first discharge mode, and the control device controls the rotor pump 200 to operate at the first rotational speed n1. If the material weight w0 measured by the weighing module 600 is less than w1, the discharge system enters the second discharge mode, and the control device controls the rotor pump 200 to operate at the second rotational speed n2. With the above settings, during the discharge process of the emulsifying tank 100, the rotor pump 200 initially operates at a higher first speed n1, resulting in a faster discharge speed. When the material height inside the emulsifying tank 100 decreases to a certain level, the material weight w0 measured by the weighing module 600 will be less than w1. At this point, the discharge system enters the second discharge mode, and the control device controls the rotor pump 200 to operate at a lower second speed n2, reducing the discharge speed. This reduces the formation of vortices at the discharge port of the emulsifying tank 100 during the discharge process, reduces air bubbles generated in the material, improves product quality, and reduces cavitation damage to the rotor pump 200. Furthermore, compared to the rotor pump 200 operating at a lower second speed n2 throughout the entire process, the discharge efficiency of the emulsifying tank 100 is higher.

[0030] According to some embodiments of the present invention, the discharge system has a third discharge mode, and the control device is set with operating parameters for the third discharge mode. The operating parameters for the third discharge mode include at least the third rotational speed n3 of the rotor pump 200 and the second starting weight w. 2， Wherein, the second starting weight w2 is less than the first starting weight w1, and the first rotational speed n1, the second rotational speed n2, and the third rotational speed n3 satisfy: n1>n2>n3; during the discharge process of the emulsion tank 100, if the material weight w0 measured by the weighing module 600 is greater than w1, the discharge system enters the first discharge mode; if the material weight w0 measured by the weighing module 600 is less than w1 and greater than w1, the system enters the first discharge mode. 2，The discharge system enters the second discharge mode, and the control device controls the rotor pump 200 to operate at the second speed n2. If the material weight w0 measured by the weighing module 600 is less than w 2， The discharge system enters the third discharge mode, and the control device controls the rotor pump 200 to operate at the third speed n3. Therefore, during the discharge process from the emulsion tank 100, as the material height inside the emulsion tank 100 decreases, the discharge system sequentially enters the first discharge mode, the second discharge mode, and the third discharge mode. Correspondingly, the speed of the rotor pump 200 also decreases sequentially, thereby reducing the discharge speed. By setting the third discharge mode, the speed of the rotor pump 200 can be more accurately controlled according to the material height inside the emulsion tank 100, ensuring the discharge efficiency of the emulsion tank 100, further reducing the formation of vortices at the discharge port of the emulsion tank 100 during the discharge process, reducing the amount of air bubbles generated in the material, further improving product quality, and reducing cavitation damage to the rotor pump 200.

[0031] It is easy to imagine that, in the specific implementation process, the discharge system can add a fourth discharge mode or more discharge modes as needed. The working parameters of all discharge modes can be set by the control device. It should be noted that, with the addition of discharge modes, the rotation speed of the rotor pump 200 can be controlled more accurately according to the material height in the emulsion tank 100. At the same time, the parameters that the control device needs to set also increase accordingly, and the control difficulty increases. Therefore, those skilled in the art should add or remove the discharge modes of the discharge system according to the actual situation.

[0032] In the specific implementation process, the control device is set with the discharge mixing speed n of the mixing mechanism. j , where n j It is 5 to 15 revolutions per minute.

[0033] With the above settings, the discharge system provided by the present invention can be used for materials with a viscosity between 0.5 and 300,000 cps. In specific implementation, those skilled in the art can adjust the working parameters of the first discharge mode, the second discharge mode and the third discharge mode according to the viscosity of the material in the emulsification tank 100 through the control device. The specific working parameters can be obtained through a limited number of tests or experience.

[0034] Specifically, in some embodiments, the rated capacity of the emulsifying tank 100 is 1000 liters. Since the density of cosmetics is similar to that of water, the emulsifying tank 100 can hold approximately 1000 kg of material. Among these, w1, w2, and w... j Satisfying: 50Kg≤w1≤120Kg, 150Kg≤w2≤300Kg, 50Kg≤w j ≤120Kg.

[0035] Among them, when the viscosity of the material increases, w1, w2 and wj The values ​​of the three can be increased accordingly.

[0036] Specifically, the viscosity of the material in emulsification tank 100 is u (unit: 10,000 cps), and the value of w1 (unit: kg) can be calculated according to the following formula:

[0037]

[0038] The value of w2 (unit: kg) can be calculated using the following formula:

[0039]

[0040] w j The value (unit: kg) can be calculated using the following formula:

[0041]

[0042] For materials with viscosities between 0.5 and 300,000 cps, those skilled in the art can calculate w1, w2, and w3 using the above formula. j The values ​​of w1, w2, and w can be determined through calculation and slightly adjusted to obtain more reasonable operating parameters, thus enabling the discharge system to have a reasonable discharge speed. Of course, those skilled in the art can also obtain w1, w2, and w through limited experiments or their own experience. j The value of .

[0043] It should be noted that w1, w2, and w j Alternatively, you can directly take the larger value, i.e., w1 equals 120Kg, w2 equals 300Kg, w j Equal to 120Kg, thus, for materials with viscosity between 0.5 and 300,000 cps, the discharge system provided by this invention can reduce the formation of vortices at the discharge port of the emulsification tank 100 during the discharge process, reduce the bubbles generated in the material, improve product quality, and reduce the damage of cavitation to the rotor pump 200.

[0044] In specific implementation, the rated speed of the rotor pump 200 is n0, wherein the first speed n1 is within 80% to 100% of the rated speed n0, the second speed n2 is within 40% to 75% of the rated speed n0, and the third speed n3 is within 5% to 20% of the rated speed n0.

[0045] When the viscosity of the material increases, the values ​​of n1, n2, and n3 can be reduced accordingly.

[0046] Specifically, the values ​​of n1, n2, and n3 can be calculated using the following formula:

[0047]

[0048]

[0049]

[0050] For materials with viscosities between 0.5 and 300,000 cps, those skilled in the art can calculate the values ​​of n1, n2, and n3 using the above formula, and then round down to obtain more reasonable operating parameters, enabling the discharge system to have a reasonable discharge rate. Of course, those skilled in the art can also obtain the values ​​of n1, n2, and n3 through a limited number of experiments or their own experience.

[0051] It should be noted that n1, n2, and n3 can also be taken as smaller values, i.e., n1 equals 80% of n0, n2 equals 40% of n0, and n3 equals 5% of n0. In this way, for materials with viscosities between 0.5 and 300,000 cps, the discharge system provided by this invention can reduce the formation of vortices at the discharge port of the emulsifying tank 100 during the discharge process, reduce the amount of air bubbles generated within the material, improve product quality, and reduce cavitation damage to the rotor pump 200. Specifically, when n1, n2, and n3 are taken as smaller values, w1, w2, and w j The value of can be appropriately reduced to improve the overall discharge efficiency of the discharge system.

[0052] In some embodiments of the present invention, when the emulsifying tank 100 has a capacity of 1000 liters, the rated speed n0 of the selected rotor pump 200 is 250 rpm. When the rotor pump 200 operates at the rated speed n0, the rated displacement of the rotor pump 200 is 6 cubic meters per hour. Thus, the actual displacement of the rotor pump 200 can be calculated according to the ratio between the actual speed of the rotor pump 200 and the rated speed n0.

[0053] Of course, in the specific implementation process, when the emulsification tank 100 has a capacity of 1000 liters, the rated speed n0 of the rotor pump 200 selected is 200 to 300 rpm, and the rated displacement of the rotor pump 200 is 4.8 to 7.2 cubic meters per hour, which can also meet the working requirements.

[0054] It should be noted that in the specific implementation process, for emulsifying tanks of different capacities, the rated displacement of the selected rotor pump 200 will be different, and the rated speed of the rotor pump 200 may also be different. In addition, for rotor pumps 200 with the same rated displacement, if the rotor pump 200 models are different, the rated speed of the rotor pump 200 may also be different. Therefore, the specific embodiments provided by the present invention should not be regarded as limitations on the rated speed and rated displacement of the rotor pump 200.

[0055] The rotor pump 200 has a weak self-priming capability, and materials with high viscosity flow into the rotor pump 200 slowly or even not at all. To address this, the emulsifying tank 100 is equipped with a pressurizing device 700 electrically connected to the control device. Before the emulsifying tank 100 discharges, the control device controls the pressurizing device 700 to supply compressed air into the emulsifying tank 100 to increase the air pressure inside the emulsifying tank 100. Thus, before the emulsifying tank 100 discharges, the pressurizing device 700 increases the air pressure inside the emulsifying tank 100, thereby forcing the material in the emulsifying tank 100 into the rotor pump 200, reducing the waiting time for the material to enter the rotor pump 200, and thus improving efficiency.

[0056] According to some embodiments of the present invention, the control device sets the air supply pressure and pressurization time of the pressurizing device 700. The air supply pressure of the pressurizing device 700 is 0.2 to 0.5 kPa, and the pressurization time of the pressurizing device 700 is 10 to 25 seconds. The higher the air supply pressure of the pressurizing device 700, the faster the material in the emulsifying tank 100 is forced into the rotor pump 200; correspondingly, the pressurization time can be reduced. When the material viscosity is high, the air supply pressure and pressurization time of the pressurizing device 700 can be increased.

[0057] According to some embodiments of the present invention, the stirring mechanism 400 includes a first rotating shaft 410 and at least two stirring rods 420 extending along the inner wall of the emulsifying tank 100 in a vertical plane. The stirring rods 420 are L-shaped, and all the stirring rods 420 are evenly arranged circumferentially along the first rotating shaft 410 and connected to the first rotating shaft 410. At least two scraper plates 430 are installed on the stirring rods 420 along their extending direction. With the above arrangement, the scraper plates 430 on the stirring mechanism 400 can sweep across a larger area of ​​the inner wall of the emulsifying tank 100, more effectively scraping away residues on the inner wall of the emulsifying tank 100, and further reducing material residue in the emulsifying tank 100 after discharge.

[0058] According to some embodiments of the present invention, an auxiliary stirring paddle is rotatably installed inside the emulsifying tank 100. The auxiliary stirring paddle is connected to the stirring drive device 500 and is located in the gap between the stirring rod 420 and the first rotating shaft 410. During the mixing of multiple raw materials in the emulsifying tank 100, the stirring drive device 500 can also drive the auxiliary stirring paddle to stir, improving the stirring quality and making the materials more uniformly mixed.

[0059] According to some embodiments of the present invention, the auxiliary stirring paddle includes a second rotating shaft 810 arranged in a vertical direction. At least two sets of stirring blades 820 are mounted on the second rotating shaft 810 along its axis. There is a gap 821 between two adjacent sets of stirring blades 820. A stirring rod 420 extends toward the gap 821 and is provided with a first stirring part 421. The first rotating shaft 410 extends toward the gap 821 and is provided with a second stirring part 411. With the above arrangement, the stirring quality of the emulsification tank 100 can be improved, and the materials can be mixed more evenly.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
