Description

Technical Field

[0001] This utility model relates to the field of emulsion preparation technology, and in particular to a liquid washing pot for emulsion preparation. Background Technology

[0002] Emulsion is a liquid cream-type skincare product. It's called emulsion because it looks pure white, like milk. Emulsions have excellent moisturizing properties and are especially suitable for use in the dry spring and autumn seasons. If you have normal skin, you can also use it in winter. Emulsions are generally prepared in a liquid washing pan, which is used for stirring and reacting low-viscosity daily chemical raw materials (such as shampoo and dishwashing liquid). The raw material for emulsion preparation is poured into the liquid washing pan and continuously stirred until the finished emulsion is produced.

[0003] In related technologies, patent CN213493299U discloses a liquid washing pot for emulsion preparation, including a liquid washing pot body, a rotating shaft disposed inside the liquid washing pot body, and a hollow foam suction cylinder connected inside the rotating shaft. A stirring paddle is fixed to the circumferential outer wall of the rotating shaft inside the liquid washing pot body. This application has the effect of reducing foam generated by the raw pulp product during the stirring production process and improving the quality stability of the emulsion product. However, although the foam suction cylinder of this device is set at an inclination, it can eliminate foam within a specific liquid level range. However, the inclination of the foam suction cylinder has a limited range for eliminating foam on the surface of the liquid at different liquid levels. When the liquid level is above or below the foam suction cylinder, it cannot eliminate foam on the surface of the liquid. Furthermore, the stirring paddle structure has a poor stirring effect on the emulsion. Therefore, we propose a liquid washing pot for emulsion preparation.

[0004] The information disclosed in this background section is only for understanding the background technology of the inventive concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A liquid washing pot for emulsion preparation includes a shell, a vacuum assembly, a stirring drum, and a foam suction assembly.

[0008] The top cover is detachably bolted to the upper end of the outer shell. A vacuum assembly is connected to the upper right side of the outer shell. The vacuum assembly includes an exhaust pipe.

The lower center of the stirring cylinder is connected to the output end of the stirring motor in the waterproof motor box. The waterproof motor box is detachably connected to the lower inner wall of the outer shell. The inner wall of the stirring cylinder is integrally formed with multiple sets of first stirring blades.

[0010] The foam suction assembly includes an annular tube with two sets of different diameters. The two sets of annular tubes are connected by a foam suction tube.

A driven gear is provided on the side of the stirring shaft at the upper end of the outer shell, and a driving gear is meshed on the right side of the driven gear. The driving gear is connected to the output end of the drive motor via a rotating shaft, and the drive motor is detachably connected to the upper end of the top cover via a connecting plate.

[0013] In some embodiments, the upper end of the connecting pipe is sealed to the infusion pipe, an infusion pump is installed on the infusion pipe, the left side of the infusion pipe is connected to the interior of the storage tank, a reflux pipe is connected to the front end of the storage tank, the right side of the reflux pipe penetrates the outer shell and extends to the top of the stirring drum, and a reflux pump is installed on the reflux pipe.

[0016] The beneficial effects of this utility model are:

[0017] The system utilizes a decompression method (reducing the internal pressure of the system via a vacuum pump) to cause bubbles to expand and burst, while simultaneously employing a foam-absorbing component to directly extract surface foam. This dual mechanism ensures efficient foam removal. A combination of first and second stirring blades provides comprehensive agitation of the emulsion, guaranteeing uniform distribution of its components. The design of the electric telescopic rod and flexible hose allows the foam-absorbing component to adjust its position according to different liquid levels, improving the equipment's applicability and flexibility. A controller monitors and operates the entire process, including the vacuum pump, drive motor, infusion pump, and return pump, enabling automated production. A storage tank collects a portion of the emulsion absorbed by the foam-absorbing component, which is then returned to the mixing drum via a return pump, reducing waste and improving resource utilization.

[0028] Reference Figure 1 , 3 4, 5, 6, A liquid washing pot for emulsion preparation, comprising an outer shell 1, a vacuum assembly 12, a stirring drum 17, and a foam suction assembly 16.

[0029] The top cover is detachably bolted to the upper end of the outer casing 1. A vacuum assembly 12 is connected to the upper right side of the outer casing 1. The vacuum assembly 12 includes an exhaust pipe 1201. One end of the exhaust pipe 1201 is connected to the interior of the outer casing 1. A vacuum pump 1202 is installed on the exhaust pipe 1201. A one-way valve 1203 is provided on the right side of the vacuum pump 1202 on the exhaust pipe 1201.

[0030] The inner wall of the outer shell 1 is rotatably equipped with a stirring drum 17. The lower center of the stirring drum 17 is connected to the output end of the stirring motor in the waterproof motor box 21. The waterproof motor box 21 is detachably connected to the lower inner wall of the outer shell 1. The inner wall of the stirring drum 17 is integrally formed with multiple sets of first stirring blades 18.

[0031] The foam suction assembly 16 includes an annular tube 1601, which has two sets of different diameters. The two sets of annular tubes 1601 are connected by a foam suction tube 1602. Multiple foam suction ports are installed at the lower end of the foam suction tube 1602. A telescopic hose 1603 is connected to the upper end of the annular tube 1601 near the wall of the outer shell 1. A connecting tube 1604 is integrally formed at the upper end of the telescopic hose 1603. The upper end of the connecting tube 1604 extends through the top cover to the upper end of the outer shell 1.

[0032] The foam on the surface of the emulsion is absorbed by the foam suction pipe 1602 and the foam suction port, and the absorbed part of the emulsion is transported to the storage tank 203. The emulsion in the stirring tank 17 is fully stirred by the cooperation of the first stirring blade 18 in the stirring drum 17 and the second stirring blade 19 on the side of the stirring shaft 5, so as to ensure the stirring effect of the emulsion.

[0033] The pressure inside the outer shell 1 is reduced by vacuum pump 1202. Under normal atmospheric pressure, foam is composed of many small bubbles separated by an emulsion film. The pressure inside these bubbles is slightly higher than the pressure of the external environment because surface tension acts on the bubble film. When the pressure inside the outer shell 1 suddenly decreases, the pressure difference between the inside and outside of the bubbles becomes smaller, causing the bubbles to have a greater tendency to expand. As the pressure decreases, the bubbles begin to expand. Due to the limited strength of the bubble film, it is easy to reach its physical limit during the expansion process, which leads to the bubble bursting. As more and more bubbles burst, the overall foam structure also collapses. In addition to directly affecting the bubbles, decompression can also promote the escape of gases dissolved in the liquid. Therefore, when the system is at a lower pressure, the gases originally dissolved in the emulsion will more easily form bubbles and rise to the liquid surface, further helping to eliminate foam.

[0034] In specific implementation of the embodiments of this utility model, such as Figure 1 , 5As shown, a stirring shaft 5 is vertically rotatably mounted in the center of the outer casing 1. The lower end of the stirring shaft 5 extends through the top cover into the interior of the stirring cylinder 17. A second stirring blade 19 is integrally formed on the side of the stirring shaft 5 and is inclined. The upper end of the stirring shaft 5 is rotatably mounted on the lower end face of the mounting bracket 3 via a rotating sleeve, and the lower end of the stirring shaft 5 is rotatably mounted inside the stirring cylinder 17 via a rotating sleeve. A driven gear 7 is mounted on the upper end of the outer casing 1 on the side of the stirring shaft 5. A driving gear 8 is meshed on the right side of the driven gear 7. The driving gear 8 is connected to the output end of the drive motor 4 via a rotating shaft. The drive motor 4 is detachably connected to the upper end of the top cover via a connecting plate. The drive motor 4 drives the driving gear 8 to rotate, and the driving gear 8 drives the driven gear 7 and the stirring shaft to rotate, thereby realizing the rotation operation of the second stirring blade 19.

[0035] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, the upper end of the connecting pipe 1604 is sealed to the infusion pipe 202. An infusion pump 201 is installed on the infusion pipe 202. The left side of the infusion pipe 202 is connected to the interior of the storage tank 203. A return pipe 204 is connected to the front end of the storage tank 203. The right side of the return pipe 204 passes through the outer shell 1 and extends to the top of the stirring drum 17. A return pump 205 is installed on the return pipe 204. The return pump 205 returns the emulsion in the storage tank 203 to the stirring drum 17.

[0036] In specific implementation of the embodiments of this utility model, such as Figure 1 , 3 As shown, the lower end of the stirring drum 17 is connected to a liquid outlet pipe 20, and a shut-off valve is installed on the liquid outlet pipe 20. The vacuum pump 1202 is detachably connected and fixed to the outer shell 1 through the support frame 15. The upper end of the annular pipe 1601 is connected and fixed to the lower movable end of the electric telescopic rod 6. Multiple sets of electric telescopic rods 6 are provided. The electric telescopic rods 6 are vertically fixed to the upper end of the top cover. The front end of the outer shell 1 is provided with an observation window 9 and a controller 10. The upper front end of the outer shell 1 is connected to a liquid inlet pipe 13. The lower right side of the outer shell 1 is connected to a liquid outlet pipe 14. Multiple sets of support columns 11 are symmetrically fixed to the lower end of the outer shell 1. The height of the foam suction pipe 1602 can be adjusted by the electric telescopic rod 6 in conjunction with the telescopic hose 1603, which is suitable for emulsions with different liquid levels.

[0037] In this embodiment, all components are general standard parts or components known to those skilled in the art. Their structures and connection principles are known to those skilled in the art through technical manuals or conventional experimental methods. First, the emulsion to be treated is added to the stirring drum 17 through the inlet pipe 13. Then, the stirring motor in the waterproof motor box 21 is started, driving the stirring drum 17 and its first stirring blade 18 to rotate. At the same time, the drive motor 4 drives the stirring shaft 5 and the second stirring blade 19 to rotate in the opposite direction through gear transmission, thereby fully stirring the emulsion. During the stirring process, the vacuum pump 1202 is started to lower the vacuum level inside the outer casing 1. The pressure in the emulsion causes the bubbles in the emulsion to expand and burst. At the same time, the foam suction component 16 extracts the foam from the surface of the emulsion through the foam suction port and finally delivers it to the storage tank 203 through the annular pipe 1601 and the telescopic hose 1603. Part of the emulsion in the storage tank 203 can be returned to the stirring drum 17 through the return pipe 204 under the action of the return pump 205 to achieve the purpose of recycling. Finally, the processed emulsion can be discharged through the outlet pipe 20. During this process, the entire process can be monitored through the observation window 9 as needed. The stirring drum 17 can be made of transparent material, including but not limited to transparent plastic.

[0038] 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 the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
