Description

Technical Field

[0001] This invention relates to the field of emulsification reaction technology, and in particular to a circulating essence emulsification reaction device. Background Technology

[0002] With the improvement of people's living standards, the demand for cosmetics such as skin creams and serums is increasing. As an emulsified skincare product containing a high concentration of active ingredients, the emulsification process in the production of serums is crucial, directly affecting the product's quality, stability, and user experience. Emulsification refers to the process of mixing two immiscible liquids through mechanical action under the action of an emulsifier to form a uniform and stable emulsion. During emulsification, the magnitude of shear force directly affects the particle size and distribution uniformity of the dispersed phase. For serum products, not only is a fine particle size of microns or even submicron is required, but also the heat-sensitive active ingredients must be protected from high-temperature damage during processing, which places higher demands on emulsification equipment.

[0003] Chinese patent document CN209715117U discloses an emulsification reaction device for daily chemical products, belonging to the technical field of daily chemical product production equipment. It aims to provide an emulsification reaction device for daily chemical products with an easily openable lid. The key technical features include a frame with an emulsification pot mounted on it. The emulsification pot includes a pot body and a lid covering the pot body. The lid has a water inlet, and a stirring shaft with stirring blades passes through it. The top of the stirring shaft passes through the lid, and a stirring motor drives its rotation. The emulsification reaction device also includes a lifting platform with a horizontally positioned lifting arm. At least one lifting cylinder is located within the lifting platform, with its top fixedly connected to the lifting arm. The lifting arm is fixedly connected to the lid. The frame also has a tilting mechanism for tilting the pot body. The lifting and tilting mechanisms facilitate the pouring of the emulsion by workers, saving manpower and improving work efficiency.

[0004] The existing technology has the following problems: Existing turbine-type emulsification and classification equipment uses the rotation of a turbine to drive the liquid into the space between the turbine and the stator, and then throws it out to achieve emulsification. However, this method results in low emulsification efficiency. Because the liquid to be emulsified is relatively viscous, the liquid that is far from the turbine is difficult to flow to the turbine, resulting in low emulsification efficiency. At the same time, prolonged emulsification may cause the liquid to heat up, affecting the product yield. Summary of the Invention

[0005] The main objective of this invention is to provide a circulating essence emulsification reaction device that can effectively solve the problem of low emulsification efficiency due to the distance between the liquid to be emulsified and the turbine.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A circulating essence emulsification reaction device includes a base, a lifting mechanism, and a protective shell mounted thereon. The upper side of the protective shell is provided with a cover. The lifting mechanism is used to drive the lifting mechanism to move up and down. The inner side of the protective shell is provided with a reaction cylinder. The inner side of the reaction cylinder is provided with an upper emulsification mechanism and a lower emulsification mechanism distributed vertically. The upper emulsification mechanism is a turbo emulsification device. The reaction cylinder is funnel-shaped, and the essence emulsion on the lower side can only enter the upper side of the reaction cylinder through the upper emulsification mechanism.

[0007] Preferably, the upper emulsification mechanism includes an electrically driven rotating rod and a first scraper located below the cap. The first scraper is used to scrape the inner wall of the upper inner side of the reaction cylinder. The outer side of the rotating rod is provided with several fixed cylinders arranged vertically, and the outer side of the lowest fixed cylinder is sleeved on the inner neck of the reaction cylinder. The outer side of the rotating rod is fixedly connected with several turbo emulsifiers arranged vertically inside the fixed cylinders. The outer side of each of the fixed cylinders is provided with several annularly distributed discharge ports.

[0008] Preferably, the inner side of the fixed cylinder is conical.

[0009] Preferably, the top view projection shape of the discharge port is arc-shaped.

[0010] Preferably, the lower emulsification mechanism includes a lifting plate, a lifting tube, and a transmission rod that are nested together from the outside to the inside and cannot rotate relative to each other. The transmission rod is driven to rotate by a motor. The upper end of the lifting tube is detachably connected to the lower end of the rotating rod through an electric connecting assembly. The lifting mechanism can drive the rotating rod to move up and down relative to the cover, and the lifting plate moves up and down synchronously when the rotating rod moves.

[0011] Preferably, the upper side of the lifting plate has a plurality of evenly distributed material inlets, and the upper side of the lifting plate is rotatably connected to a plurality of sealing plates for sealing the material inlets. When the lifting plate moves down, the sealing plates release the sealing of the material inlets.

[0012] Preferably, a push-pull frame is fixedly connected to the outside of the lifting pipe, and the outside of the push-pull frame is provided with several annularly distributed second scrapers for scraping the lower inner wall of the reaction cylinder.

[0013] Preferably, the lower end of the second scraper is rotatably connected to the upper edge of the lifting plate, and the second scraper and the push-pull frame are slidably connected to each other. The bottom outer side of the lifting tube is fixedly connected to a push plate for driving the lifting plate to move upward, and the push plate is located on the lower side of the lifting plate. When the lifting plate is at its lowest position, the second scraper is in a horizontal state.

[0014] Preferably, a plurality of annularly distributed circulation pipes are fixedly connected to the outer side of the reaction cylinder, the upper and lower ends of the circulation pipes are connected to the upper and lower sides of the inner cavity of the reaction cylinder, and a plurality of vertically distributed heat sinks are fixedly connected to the outer side of each of the circulation pipes.

[0015] Preferably, a spiral-shaped air duct is fixedly connected between the inner side of the protective shell and the outer side of the reaction cylinder, and several air ducts are distributed in a ring. The upper and lower ends of the air duct are fixedly connected to the upper and lower sides of the base. The heat sink is located inside the air duct. The inner cavity of the air duct is connected to the outer side of the base. An air supply mechanism for blowing air into the air duct is provided on the upper side of the cover.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a circulating essence emulsification reaction device. Based on the cooperation of a lifting mechanism, a cap, a reaction cylinder, an upper emulsification mechanism, a rotating rod, a first scraper, a fixed cylinder, a turbo emulsifier, a discharge port, a lower emulsification mechanism, a lifting plate, a transmission rod, a lifting pipe, a push plate, a feed port, a sealing plate, a second scraper, and a push-pull frame, the reaction cylinder is shaped so that the lowermost fixed cylinder occupies the neck of the reaction cylinder. This allows the essence emulsion in the reaction cylinder to flow from bottom to top when the turbo emulsifier scrapes, while the lower emulsification mechanism assists in pushing the lower essence emulsion to the upper emulsification mechanism, thereby improving the emulsification efficiency of the essence emulsion.

[0017] This invention provides a circulating essence emulsification reaction device. Based on the cooperation of a cap, reaction cylinder, upper emulsification mechanism, circulation pipe, heat sink and air guide pipe, the essence emulsion inside the upper part of the reaction cylinder is sent to the lower part of the reaction cylinder through the circulation pipe to realize the circulation flow of materials. During this process, the essence emulsion passing through the circulation pipe is cooled down to avoid the problem of the essence emulsion overheating during the emulsification process, which would affect the product yield.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example 1, as Figures 1-4 As shown, a circulating essence emulsification reaction device includes a base 1, a lifting mechanism 3, and a protective shell 2 mounted thereon. The upper side of the protective shell 2 is provided with a cover 4. The lifting mechanism 3 is used to drive the lifting mechanism 4 to move up and down. The lifting mechanism 3 is a conventional lifting device used to automatically drive the cover 4 to move up and down to realize the overall opening and closing of the device. This is existing technology and will not be described in detail here. The inner side of the protective shell 2 is provided with a reaction cylinder 5. The inner side of the reaction cylinder 5 is provided with an upper emulsification mechanism 6 and a lower emulsification mechanism 7 distributed vertically. The upper emulsification mechanism 6 is a turbo emulsification device. Turbo emulsification devices are existing conventional emulsification devices. They use a rotor and stator to generate centrifugal force and vacuum effect by rotating the rotor at high speed, which draws the material from the lower part of the working head into the shearing chamber to achieve emulsification. This is existing technology and will not be described in detail here. The reaction cylinder 5 is funnel-shaped, and the essence emulsion on the lower side can only enter the upper side of the reaction cylinder 5 through the upper emulsification mechanism 6.

[0022] Example 2, as Figures 2-6As shown, the upper emulsification mechanism 6 includes an electrically driven rotating rod 61 and a first scraper 62 located on the lower side of the cap 4. The first scraper 62 is used to scrape the inner wall of the upper inner side of the reaction cylinder 5. The first scraper 62 is used to prevent the essence from adhering to the inner wall of the reaction cylinder 5, which would make it difficult for the essence to flow in that part, thus resulting in poor emulsification efficiency of the essence in that part. The outer side of the rotating rod 61 is provided with several fixed cylinders 63 arranged vertically. The fixed cylinders 63 are fixedly connected to the bottom of the cover 4 by the outer bracket and remain stationary, so that the fixed cylinders 63 act as stators. The outer side of the lowermost fixed cylinder 63 is sleeved on the inner neck of the reaction cylinder 5, and the outer side of the lowermost fixed cylinder 63 is in close contact with the inner neck of the reaction cylinder 5. The outer side of the rotating rod 61 is fixedly connected with several turbo emulsifiers 64 arranged vertically and placed inside the fixed cylinders 63. The turbo emulsifiers 64 act as rotors. The outer side of each of the fixed cylinders 63 is provided with several annularly distributed discharge ports 65. The purified material that has been sheared and crushed flows out of the inner side of the fixed cylinders 63 from the discharge ports 65.

[0023] Preferably, the inner side of the fixed cylinder 63 is conical. The conical structure allows the essence emulsion entering the fixed cylinder 63 to move upwards under the rotation of the turbine emulsifier 64, and the rotation speed gradually increases, thereby improving the emulsification efficiency.

[0024] Preferably, the top view projection shape of the outlet 65 is arc-shaped. The arc-shaped outlet 65 causes the essence to generate a lateral rotational force when it flows out of the inner side of the fixed cylinder 63 from the outlet 65, and then relies on this part of the rotational force to stir the essence on the outer side of the fixed cylinder 63.

[0025] It should be noted that the rotation of the rotating rod 61 drives the turbine emulsifier 64 to rotate. During the rotation of the turbine emulsifier 64, in conjunction with the fixed cylinder 63, the essence emulsion on the lower side of the inner side of the reaction cylinder 5 enters the fixed cylinder 63 and is then sprayed out from the outlet 65.

[0026] Example 3, as Figures 5-8 As shown, the lower emulsification mechanism 7 includes a lifting plate 71, a lifting tube 73, and a transmission rod 72 that are nested together from the outside to the inside and cannot rotate relative to each other. The contact surfaces of the lifting plate 71, the transmission rod 72, and the lifting tube 73 are in the form of polygonal prisms to prevent relative rotation between the three. The transmission rod 72 is driven by a motor. A support boss is provided between the protective shell 2 and the base 1. The motor that drives the transmission rod 72 is located between the protective shell 2 and the base 1. The upper end of the lifting tube 73 is detachably connected to the lower end of the rotating rod 61 via an electric connecting assembly. This electric connecting assembly can be in the form of an elastic buckle, through which a plug is inserted into a plug hole. A horizontally electrically movable fixing rod is provided on the plug rod. When the fixing rod is moved out, the lifting tube 73 and the rotating rod 61 are fixedly connected together. This is existing technology and will not be described in detail here. The lifting mechanism 3 can drive the rotating rod 61 to move up and down relative to the cover 4. The lifting mechanism 3 adopts two sets of lifting components, one of which drives the other to move up and down synchronously with the cover 4. The component that moves up and down synchronously with the cover 4 is connected to the rotating rod 61, and the lifting plate 71 moves up and down synchronously when the rotating rod 61 moves.

[0027] Preferably, the upper side of the lifting plate 71 is provided with a plurality of evenly distributed material passages 75. The setting of the material passages 75 avoids the problem of high resistance when the lifting plate 71 moves downward. The upper side of the lifting plate 71 is rotatably connected with a plurality of sealing plates 76 for blocking the material passages 75. The setting of the sealing plates 76 avoids the problem that the lifting plate 71 is difficult to push the material upward due to the presence of the material passages 75. When the lifting plate 71 moves downward, the sealing plate 76 releases its blockage of the feed inlet 75. At the same time, the sealing plate 76 is provided with evenly distributed through holes. Even though the sealing plate 76 blocks the feed inlet 75, a small amount of material still leaks down from the through holes during the upward movement of the lifting plate 71, avoiding the problem of too much material moving upward at once. When the lifting plate 71 moves upward, the material on the upper side of the sealing plate 76 presses down on the sealing plate 76, causing the sealing plate 76 to block the feed inlet 75. When the lifting plate 71 moves downward, the material on the lower side of the sealing plate 76 pushes the sealing plate 76 upward, causing the sealing plate 76 to rotate upward and open the feed inlet 75.

[0028] Preferably, a push-pull frame 78 is fixedly connected to the outside of the lifting pipe 73. The rotation of the lifting pipe 73 drives the push-pull frame 78 to rotate. The outside of the push-pull frame 78 is provided with several annularly distributed second scrapers 77 for scraping the lower inner wall of the inner side of the reaction cylinder 5. The rotation of the push-pull frame 78 drives the second scrapers 77 to revolve. The function of the second scrapers 77 is the same as that of the first scraper 62.

[0029] Preferably, the lower end of the second scraper 77 is rotatably connected to the upper edge of the lifting plate 71. The second scraper 77 and the push-pull frame 78 are slidably connected and can rotate relative to each other. When the lifting tube 73 and the lifting plate 71 move up and down relative to each other, the push-pull frame 78 and the second scraper 77 move relative to each other, causing the second scraper 77 to rotate, thereby controlling the angle between the upper side of the second scraper 77 and the lifting plate 71. The outer bottom of the lifting tube 73 is fixedly connected to a push plate 74 for driving the lifting plate 71 to move upward. The push plate 74 is located below the lifting plate 71. When the lifting plate 71 is at its lowest position, the second scraper 77 is horizontal. In this state, there is a gap between the upper side of the push plate 74 and the lower side of the lifting plate 71. This can be achieved by setting a pipe in the middle of the upper side of the lifting plate 71, and relying on the push plate 74 to push the inner upper surface of the pipe to achieve the purpose of delaying the upward push of the lifting plate 71 during the upward movement of the lifting pipe 73. Alternatively, a pipe can be set in the middle of the bottom inside the reaction cylinder 5, and the gap between the push plate 74 and the lifting plate 71 when the lifting plate 71 is at its lowest position can be solved by inserting the push plate 74 into the pipe. Or other forms may also be used.

[0030] It should be noted that the lifting mechanism 3 drives the rotating rod 61 to move up and down, which in turn drives the lifting pipe 73 to move up and down. When the lifting pipe 73 moves up and down, it drives the push plate 74 to move up and down. When the push plate 74 moves up to a certain extent, it pushes the lifting plate 71 up, causing the lifting plate 71 to move up and push the material up. The lifting pipe 73 moves up relative to the lifting plate 71, causing the second scraper 77 to open. The motor drives the transmission rod 72 to drive the lifting plate 71 and the second scraper 77 to rotate. The push-pull frame 78 and the second scraper 77 work together to stir the material in the lower part of the inner side of the reaction cylinder 5. When the lifting plate 71 is at its lowest position, the movement of the lifting pipe 73 allows the angle of the second scraper 77 to be adjusted, thereby performing a sweeping agitation on the bottom of the inner side of the reaction cylinder 5.

[0031] Example 4, as Figures 9-11 As shown, several annularly distributed circulation pipes 8 are fixedly connected to the outside of the reaction cylinder 5. The material in the circulation pipes 8 can only flow in one direction. A valve plate with the same principle as the sealing plate 76 can be set at the lower end of the circulation pipes 8, so that the lower end of the circulation pipes 8 is blocked when the lifting plate 71 moves down, so as to avoid the material being pushed into the circulation pipes 8 when the lifting plate 71 moves down, which would cause the material in the circulation pipes 8 to flow back. The upper and lower ends of the circulation pipes 8 are connected to the upper and lower sides of the inner cavity of the reaction cylinder 5. Several vertically distributed heat sinks 9 are fixedly connected to the outside of the several circulation pipes 8. The heat sinks 9 are used to increase the contact area between the outer surface of the heat sinks 9 and the air.

[0032] Preferably, a spiral-shaped air duct 10 is fixedly connected between the inner side of the protective shell 2 and the outer side of the reaction cylinder 5, and several air ducts 10 are distributed in a ring. The structure of the air duct 10 allows it to deliver air to a small section of each heat sink 9. The shape of the air duct 10 also ensures that the airflow is directed from the side to the heat sink 9. The upper and lower ends of the air duct 10 are fixedly connected to the upper and lower sides of the base 1. The heat sink 9 is located inside the air duct 10. The inner cavity of the air duct 10 is connected to the outer side of the base 1. The upper side of the cover 4 is provided with an air delivery mechanism for blowing air through the air duct 10. The air delivery mechanism is a component used for blowing air in existing heat dissipation equipment, such as an air pump or fan blade.

[0033] It should be noted that when the cover 4 is closed, the air supply mechanism on the cover 4 blows air into the air duct 10, and the cooling air moves from the top to the bottom, passing through the heat sink 9 on each circulation pipe 8, thereby cooling it.

[0034] The working principle of this invention is as follows: First, the rotating rod 61 rotates, driving the turbo emulsifier 64 to rotate. During the rotation of the turbo emulsifier 64, in conjunction with the fixed cylinder 63, the essence emulsion on the lower inner side of the reaction cylinder 5 enters the fixed cylinder 63 and is then sprayed out from the outlet 65. The lifting mechanism 3 drives the rotating rod 61 to move up and down, which in turn drives the lifting pipe 73 to move up and down. When the lifting pipe 73 moves up and down, it drives the push plate 74 to move up and down. When the push plate 74 moves up to a certain extent, it pushes the lifting plate 71 upward, causing the lifting plate 71 to move upward and push the material upward. The lifting pipe 73 moves upward relative to the lifting plate 71, causing the second scraper 77 to open. Relying on the motor-driven transmission rod 72, the lifting plate 71 and the second scraper 77 are driven to rotate. The push-pull frame 78 and the second scraper 77 work together to agitate the material in the lower inner side of the reaction cylinder 5. Through the shape of the reaction cylinder 5 and the fact that the lowermost fixed cylinder 63 occupies the neck of the reaction cylinder 5, the turbo emulsifier 64 scrapes the material inside the reaction cylinder 5. The essence emulsion flows from bottom to top, while the lower emulsification mechanism 7 assists in pushing the lower essence emulsion to the upper emulsification mechanism 6, thereby improving the emulsification efficiency of the essence emulsion. Finally, the material in the circulation pipe 8 can only flow in one direction. A valve plate with the same principle as the sealing plate 76 can be set at the lower end of the circulation pipe 8, so that the lifting plate 71 can block the lower end of the circulation pipe 8 during the downward movement, avoiding the problem of material backflow in the circulation pipe 8 when the lifting plate 71 moves downward. When the cover 4 is closed, the air supply mechanism on the cover 4 blows air into the air duct 10. The cooling air moves from the upper end to the lower end, passing through the heat sink 9 on each circulation pipe 8 to cool it down. The essence emulsion on the upper side of the reaction cylinder 5 is sent to the lower side of the reaction cylinder 5 through the circulation pipe 8 to realize the circulation flow of the material. During this process, the essence emulsion passing through the circulation pipe 8 is cooled down, avoiding the problem of the essence emulsion overheating during the emulsification process, which would affect the product yield.
