Description

Technical Field

[0001] This application relates to the field of mixing and stirring equipment, and more particularly to a liquid fragrance blending device. Background Technology

[0002] Compared to perfumes, liquid fragrances generally do not come into contact with the human body, so they use a variety of solvents, such as isopropanol, dipropylene glycol, and mineral oil. In addition, liquid fragrances also contain different raw materials such as fixatives, essential oils, and fragrances. Some raw materials are difficult to mix, such as solid crystalline musk and ambergris lactone, which require higher temperatures to dissolve better. Furthermore, different raw materials have different densities, which may cause stratification, making it difficult to mix them thoroughly during stirring and resulting in low mixing efficiency.

[0003] Chinese patent application CN211098599U, entitled "Perfume Ingredient Mixing Tank," discloses a perfume ingredient mixing tank. This patent relates to the technical field of mixing tanks and aims to solve the technical problem of uneven mixing caused by the stratification of ingredients in a perfume mixture. The key technical feature is a perfume ingredient mixing tank with three support feet evenly arranged around its circumference at the bottom. A pneumatic motor is located at the center of the top of the tank. A vertically aligned stirring shaft is installed inside the tank, with the pneumatic motor's rotating shaft extending into the tank and connecting to the stirring shaft for transmission. Multiple horizontally arranged stirring blades are evenly distributed along the vertical direction on the stirring shaft. Each stirring blade has a turbulence inlet, and turbulence-inducing plates intersecting the plane of the blades are installed within the turbulence inlet. While this design can improve the mixing effect, denser ingredients will still accumulate at the bottom within a certain time, resulting in low mixing efficiency.

[0004] Chinese patent application CN206391943U, entitled "An Apparatus for Perfume Blending," discloses an apparatus for perfume blending, comprising a blending tank body and an impurity absorption device. A motor is fixedly connected to the top of the blending tank body, and the motor's output shaft is fixedly connected to the top of a stirring shaft. Two sets of stirring blades are mounted on the stirring shaft. A feed inlet is located at the upper part of the blending tank body, and the impurity absorption device is located at the center of the bottom of the blending tank body. The impurity absorption device is connected to a three-way valve, and one end of the three-way valve is fixedly connected to a circulation pump. The circulation pump is connected to a filter device via a return pipe, and the filter device is fixedly connected to the upper outer side of the blending tank body. This patent's use of a circulation pump increases the complexity of the equipment. A well-sealed pump body is expensive, and the structure of a common pump body can affect the purity of the perfume, potentially causing lubricant leakage and resulting in an unpleasant odor. Utility Model Content

[0005] This application provides a liquid fragrance blending device to at least solve the mixing efficiency problem existing in the prior art.

[0006] According to this application, a liquid fragrance blending device is provided, including a tank, a drive unit, a transmission shaft, blades, and a circulation pipe. The tank has an inner cavity, and the blades are disposed on the transmission shaft. The drive unit can drive the transmission shaft to rotate. The blades are located in the inner cavity of the tank. When the blades rotate with the transmission shaft, they can generate a main liquid flow in a certain direction, either axially, radially, or circumferentially. The circulation pipe has an inlet end and a return end. The inlet end of the circulation pipe is disposed in the direction of the main liquid flow and extends a certain distance along the direction of the main liquid flow. The return end of the circulation pipe is disposed at the upper end of the tank.

[0007] Compared with existing technologies, the liquid fragrance blending device of this application has the following advantages: With the help of the circulation pipe, the raw materials inside the tank can circulate, improving mixing efficiency. This avoids the phenomenon of low-density raw materials remaining in the higher areas for extended periods while high-density raw materials are largely distributed at the bottom, creating effective vertical convection. Furthermore, the technical solution of this application achieves circulation without the need for a separate drive pump, simplifying the equipment structure, reducing production costs, and preventing fragrance contamination and odor generation.

[0008] In one embodiment, the bottom of the tank is set as a cone, the inlet end of the circulation pipe is set at the bottom of the cone-shaped tank, and the blades are set as axial flow blades that can generate axial main liquid flow. The cone structure facilitates the internal liquid to gather at the bottom and transfer through the pipe. The axial main liquid flow can enter the circulation pipe to realize liquid circulation flow. In this way, the liquid at the bottom can enter the top, realize the mixing of liquids at different heights, and avoid liquid stratification for a long time.

[0009] In one embodiment, the blade is a helical blade or tilted at a certain angle relative to the drive shaft so that the blade generates an axial main liquid flow when it rotates, so that the blade can exert an axial force on the liquid when it rotates.

[0010] In one embodiment, the drive shaft is arranged with a first blade, a second blade, and a third blade from top to bottom. The first blade is an inclined blade, the second blade includes a stirring plate parallel to the axial direction of the drive shaft and an inclined guide plate, with the stirring plate and the guide plate intersecting at an obtuse angle, and the third blade is a helical blade that mainly provides axial liquid flow. The multi-shaped blades facilitate the mixing of raw materials with different viscosities and densities, increase mixing efficiency, and make the mixing more thorough within a certain time.

[0011] In one embodiment, the inlet end of the circulation pipe is located on the side wall of the tank, and the side wall of the tank is provided with a guide groove. A baffle plate is provided above the guide groove, and the guide groove or circulation pipe is arranged tangentially along the circumference of the tank. The high rotation speed of the liquid mixing blades can generate a large velocity in the tangential direction. The guide groove and baffle plate can guide the flowing liquid to the circulation pipe. Under the action of pressure and inertia, the liquid enters the guide pipe and flows along the guide pipe to the top of the tank, realizing the circulating flow and mixing of raw materials.

[0012] In one embodiment, the blades are arranged parallel to the drive shaft along the axial direction so that the blades do not generate axial force. Under the same power, this can increase the tangential speed and increase the speed of liquid circulation in the tangential circulation pipe.

[0013] In one embodiment, the circulation tube is equipped with a filter box containing a filter layer, which facilitates the filtration of particulate impurities during circulation, resulting in a purer liquid fragrance.

[0014] In one embodiment, the circulation pipe is equipped with a one-way air valve or a three-way valve. The one-way air valve can introduce air into the circulation pipe under a certain pressure difference, while the three-way valve can switch the state of the inlet end of the circulation pipe from being connected to the tank to being connected to the outside. In this way, after the circulation flow ends, the liquid in the circulation pipe can be pumped into the tank using a negative pressure device, avoiding liquid overflow to the outside and causing waste.

[0015] In one embodiment, the upper end of the tank is provided with a material inlet and a feed pipe. The material inlet is equipped with a filter plate and a sealing cap, and the feed pipe is equipped with a cap or connected to a pipe with a valve. The filter plate is designed to be detachable, which facilitates the addition of solid and liquid raw materials in different ways. The feed pipe can be directly connected to a material conveying pipeline, especially for large quantities of solvent, which can be directly conveyed through the pipeline, making it faster and more convenient.

[0016] In one embodiment, the tank includes an inner shell, an outer shell, and a water tank shell. The inner shell is located inside the outer shell, and the water tank shell is disposed between the inner shell and the outer shell, fixed to the outside of the inner shell. A water cavity is formed between the water tank shell and the inner shell. The water cavity is equipped with a temperature detection device and a heating element, and is connected to a drain pipe and an exhaust pipe. The water inside the water tank shell needs to be replaced periodically, and the drain pipe and exhaust pipe are equipped with corresponding valves to control their opening and closing.

[0020] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1 and Figure 2As shown, a liquid fragrance blending device includes a tank 1, a drive unit 2, a transmission shaft 3, blades 4, and a circulation pipe 5. The tank 1 has an inner cavity 10. The blades 4 are disposed on the transmission shaft 3. The drive unit 2 can drive the transmission shaft 3 to rotate. The blades 4 are located in the inner cavity 10 of the tank 1. When the blades 4 rotate with the transmission shaft 3, they can generate a main liquid flow in a certain direction in the axial, radial, or circumferential direction. The circulation pipe 5 has an inlet end 51 and a return end 52. The inlet end 51 of the circulation pipe 5 is disposed in the direction of the main liquid flow and extends a certain distance along the direction of the main liquid flow. The return end 52 of the circulation pipe 5 is disposed at the upper end of the tank 1.

[0022] Example 1: like Figure 1 As shown, as a further improvement, the can 1 is a cylindrical container with supporting feet 11 at the bottom, allowing it to be installed on a platform at a certain height or on the ground. The can 1 can be made of stainless steel, providing good corrosion resistance. The drive component 2 is an explosion-proof geared motor, located above the can 1, with the drive shaft 3 connected to it for transmission. The drive shaft 3 is vertically inserted into the can 1 from directly above. To facilitate the blending of different fragrances, the can 1 can have a multi-layered structure for easy heating. The rotation speed of the drive shaft 3 varies depending on the raw material being blended, typically ranging from 300 to 900 revolutions per minute.

[0023] like Figure 4 and Figure 5 As shown, as a further improvement, the bottom of the tank 1 is set in a conical shape to collect the liquid at the bottom. The inlet end 51 of the circulation pipe 5 is located at the bottom of the conical tank 1, and the blades 4 are set as axial flow blades 4 to generate the main axial liquid flow. The specific shape of the blades 4 is not limited and can be calculated and designed according to relevant design manuals.

[0024] like Figure 2 and Figure 3 As shown, in one embodiment, the blade 4 is a helical blade 4 or tilted at a certain angle relative to the drive shaft 3 so that the blade 4 generates an axial main fluid flow when it rotates.

[0025] like Figure 2 and Figure 3As shown, in one embodiment, the drive shaft 3 is arranged from top to bottom with a first blade 41, a second blade 43, and a third blade 42. The first blade 41 is an inclined blade, and multiple through holes are provided on the first blade 41 to reduce the resistance to the rotation of the blade 4 and increase the mixing effect. The second blade 43 includes a stirring plate 44 parallel to the axial direction of the drive shaft 3 and an inclined guide plate 45. The stirring plate 44 and the guide plate 45 intersect at an obtuse angle. The stirring plate 44 is provided with multiple through holes to reduce the resistance during the rotation process. The guide plate 45 generates an axial force. The stirring plate 44 mainly plays the role of mixing liquids. The third blade 42 is a spiral blade 4 that mainly provides axial liquid flow. The length of one side of the first blade 41 and the second blade 43 is close to the radius of the tank 1, and the length of one side of the third blade 42 is the same as the diameter of the circulation pipe 5 or within a 20% difference, thus providing effective power for the circulation flow of the circulation pipe 5.

[0026] like Figure 6 and Figure 7 As shown, in one embodiment, the circulation pipe 5 is provided with a filter box 53, and a filter layer 55 is provided inside the filter box 53. The filter layer 55 is arranged in the vertical direction. The filter box 53 is provided with a liquid storage area 54, which is located below the filter layer 55. Some impurities will fall into the liquid storage area 54 after being blocked by the filter layer 55.

[0027] like Figure 7 and Figure 9 As shown, a flow guide pipe 12 is provided below the tank body 1, and a flow guide valve 14 is installed on the flow guide pipe 12, such as... Figure 7 As shown, the flow guide valve 14 is connected to the circulation pipe 5, as follows: Figure 9 As shown, the flow guide valve 14 is connected to the filling nozzle 15 to facilitate fragrance filling or transfer. The flow guide valve 14 can also be directly connected to other pipelines to achieve the transfer of liquid fragrance.

[0028] In one embodiment, the circulation pipe 5 is equipped with a one-way air valve 13 or a three-way valve. The one-way air valve 13 can introduce air into the circulation pipe 5 under a certain pressure difference, and the three-way valve can switch the state of the liquid inlet 51 of the circulation pipe 5 connected to the tank 1 to the state of connection with the outside. Figure 8 As shown, the one-way air valve 13 is located on the guide valve 14 near one end of the circulation pipe 5. When the guide valve 14 is closed, the liquid in the circulation pipe 5 stops flowing, applying negative pressure inside the tank 1. The one-way air valve 13 then opens, allowing air to enter the circulation pipe 5 and emptying the liquid inside. Figure 9 As shown, after the liquid in the circulation pipe 5 is drained, the filling nozzle 15 can be replaced and connected to the flow guide valve 14, or other flow guide pipes 12 can be connected to the flow guide valve 14.

[0029] like Figure 1 , Figure 5 and Figure 7As shown, in one embodiment, the upper end of the tank 1 is provided with a material inlet 16 and a feed pipe 17. The material inlet 16 is provided with a filter plate 18 and a sealing cover 19. The sealing cover 19 can seal the material inlet 16 to prevent the leakage of volatile gases. The feed pipe 17 is provided with a cover or connected to a pipe with a valve. The feed pipe 17 can be connected to a pipe to realize automatic material addition.

[0030] like Figure 1 , Figure 5 and Figure 7 As shown, in one embodiment, the tank 1 includes an inner shell 6, an outer shell 7, and a water tank shell 8. The inner shell 6 is located inside the outer shell 7, and the water tank shell 8 is disposed between the inner shell 6 and the outer shell 7. The water tank shell 8 is fixed outside the inner shell 6, and a water cavity 9 is formed between the water tank shell 8 and the inner shell 6. The water cavity 9 is equipped with a temperature detection device 20 and a heating pipe 21, and the water cavity 9 is connected to a drain pipe 22 and an exhaust pipe 23. The outer shell 7 can provide a certain degree of heat preservation and prevent scalding from direct contact with the water tank. The heating pipe 21 is disposed on the side wall of the tank 1 and can penetrate the outer shell 7 and the water tank shell 8 to be inserted into the water tank shell 8 to heat water and indirectly heat the raw materials in the inner shell 6, avoiding excessively high local temperatures.

[0031] Example 2: like Figure 10 As shown, the difference from Embodiment 1 is that the inlet end 51 of the circulation pipe 5 is located on the side wall of the tank 1. The side wall of the tank 1 is provided with a guide groove 24, and a baffle plate 25 is provided above the guide groove 24. The baffle plate 25 restricts the axial liquid flow in a certain direction, making the circumferential and radial liquid flow larger. The guide groove 24 or the circulation pipe 5 is arranged tangentially along the circumference of the tank 1. The baffle plate 25 is located on the outer edge of the guide groove 24, and can also extend tangentially. It also has a certain width in the radial direction, which is in the range of 10mm-30mm. If it is too large, it will affect the stirring and mixing effect. The return end 52 of the circulation pipe 5 is located on the side wall at the upper end of the tank 1, which can realize the circulation flow of the liquid. Radially extending baffles 46 are provided inside the tank 1.

[0032] like Figure 10 As shown, in one embodiment, the blade 4 is arranged parallel to the drive shaft 3 along the axial direction of the drive shaft 3 so that the blade 4 does not generate axial force.
