Description

Technical Field

[0001] This application relates to the field of fluid mixing, and more particularly to a mixing device. Background Technology

[0002] In industrial applications, fluid mixing is frequently required. Traditional methods for achieving uniform mixing, primarily mechanical stirring and airflow agitation, are ineffective and labor-intensive. In conventional flow battery systems, the electrolyte requires external stirring pumps to ensure uniform concentration and maintain efficient battery operation. However, the design of external stirring pumps not only increases system complexity but also consumes significant energy, reducing overall energy efficiency. Utility Model Content

[0003] The main objective of this application is to provide a mixing device that addresses the problems of existing fluid mixing devices requiring external stirrers, resulting in low energy efficiency and poor mixing performance.

[0004] In a first aspect, embodiments of this application provide a mixing apparatus, comprising:

[0005] A tank body having a receiving cavity;

[0006] The liquid inlet pipe has a first liquid inlet and a first liquid outlet, and the end of the liquid inlet pipe with the first liquid outlet is located in the accommodating cavity. Liquid can enter the liquid inlet pipe through the first liquid inlet and be discharged into the accommodating cavity through the first liquid outlet.

[0007] The liquid outlet pipe has a second inlet and a second outlet, and one end of the liquid outlet pipe with the second inlet is located in the accommodating cavity. At least a portion of the liquid in the accommodating cavity can enter the liquid outlet pipe through the second inlet and be discharged from the accommodating cavity through the second outlet.

[0008] A flow guiding mechanism, comprising a flow diversion component, a first flow guiding component, and a second flow guiding component, wherein the flow diversion component is disposed corresponding to the first drain port, and a first distance exists between the side of the flow diversion component away from the bottom of the tank and the first drain port;

[0009] The first flow guiding component is disposed on the side of the flow dividing component away from the bottom of the tank and forms a first flow guiding cavity with a first opening. The second flow guiding component is disposed in the first flow guiding cavity and forms a second flow guiding cavity with a second opening. The first flow guiding cavity is connected to the receiving cavity through the first opening. The second flow guiding cavity is connected to the first flow guiding cavity through the second opening. The second liquid inlet is located in the second flow guiding cavity.

[0010] As can be seen from the technical solution provided in this application, the mixing device provided in this application does not require external stirring equipment, which simplifies the system design. By setting a flow guiding mechanism with a flow splitting component, a first flow guiding component and a second flow guiding component, multi-stage flow guiding is formed, so that the fluid naturally forms eddies and turbulence during the flow in the tank, thereby achieving uniform mixing and improving energy efficiency.

[0011] Secondly, embodiments of this application also provide a mixing apparatus, comprising:

[0012] A tank body having a receiving cavity;

[0013] The liquid inlet pipe has a first liquid inlet and a first liquid outlet, and the end of the liquid inlet pipe with the first liquid outlet is located in the accommodating cavity. Liquid can enter the liquid inlet pipe through the first liquid inlet and be discharged into the accommodating cavity through the first liquid outlet.

[0014] The liquid outlet pipe has a second inlet and a second outlet, and one end of the liquid outlet pipe with the second inlet is located in the accommodating cavity. At least a portion of the liquid in the accommodating cavity can enter the liquid outlet pipe through the second inlet and be discharged from the accommodating cavity through the second outlet.

[0015] A flow guiding mechanism, the flow guiding mechanism including a second flow guiding component, the second flow guiding component forming a second flow guiding cavity with a second opening on the side near the bottom of the tank, the second flow guiding cavity communicating with the receiving cavity through the second opening;

[0016] The liquid inlet pipe is connected to the second flow guide component and passes through the second flow guide cavity formed by the second flow guide component. The first liquid outlet of the liquid inlet pipe is located outside the second flow guide cavity. The liquid outlet pipe is connected to the second flow guide component, and the second liquid inlet is located inside the second flow guide cavity and communicates with the second flow guide cavity.

[0017] As can be seen from the technical solution provided in this application, the mixing device provided in this application, by setting a second flow guiding component facing the bottom opening of the tank, allows the fluid to flow into the tank through the first drain port and form a backflow effect at the bottom of the tank, thereby forming eddies and turbulence in the tank's accommodating cavity, thus achieving a uniform mixing effect.

[0033] The technical solutions of 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, 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.

[0034] In the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] It is understood that descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] Please refer to Figures 1 to 3 The first embodiment of this application provides a mixing device 100, including a tank 10, an inlet pipe 20, an outlet pipe 30, and a flow guiding mechanism 40.

[0038] The tank body 10 has a accommodating cavity 101. The liquid inlet pipe 20 has a first liquid inlet 21 and a first liquid outlet 22. The end of the liquid inlet pipe 20 with the first liquid outlet 22 is located in the accommodating cavity 101. Liquid can enter the liquid inlet pipe 20 through the first liquid inlet 21 and be discharged into the accommodating cavity 101 through the first liquid outlet 22.

[0039] The liquid outlet pipe 30 has a second liquid inlet 31 and a second liquid outlet 32, and one end of the liquid outlet pipe 30 with the second liquid inlet 31 is located in the accommodating cavity 101. At least part of the liquid in the accommodating cavity 101 can enter the liquid outlet pipe 30 through the second liquid inlet 31 and be discharged from the accommodating cavity 101 through the second liquid outlet 32.

[0040] The flow guiding mechanism 40 includes a flow diversion component 41, a first flow guiding component 42 and a second flow guiding component 43. The flow diversion component 41 is provided corresponding to the first drain port 22, and there is a first gap between the side of the flow diversion component 41 away from the bottom of the tank body 10 and the first drain port 22. The first gap can be set as needed, for example, the first gap is 2-20cm.

[0041] The first flow guiding component 42 is disposed on the side of the flow dividing component 41 away from the bottom of the tank 10 and forms a first flow guiding cavity 423 with a first opening. The second flow guiding component 43 is disposed in the first flow guiding cavity 423 and forms a second flow guiding cavity 433 with a second opening. The first flow guiding cavity 423 is connected to the receiving cavity 101 through the first opening. The second flow guiding cavity 433 is connected to the first flow guiding cavity 423 through the second opening. The second liquid inlet 31 is located in the second flow guiding cavity 433.

[0042] It is understood that the first opening faces the top of the tank 10, and the second opening faces the bottom of the tank 10.

[0043] For example, such as Figure 3 As shown, the fluid flows into the accommodating cavity 101 of the tank 10 from the first inlet 21 of the inlet pipe 20 and flows out along the first outlet 22. After passing through the diversion component 41, the fluid forms a planar multi-directional diversion at the bottom of the tank 10, flowing in various directions within the accommodating cavity 101. After the diverted fluid encounters the inner wall of the tank 10, the flow direction changes, naturally generating eddies and turbulence within the tank 10, allowing the fluid within the tank 10 to be further fully mixed. After the mixed fluid collides with the wall of the first guide component 42 and is disturbed, it flows along the first guide component 42 through the second opening into the second guide cavity 433. After being mixed again in the second guide cavity 433, it flows out from the second inlet 31 of the outlet pipe 30 and is discharged from the accommodating cavity 101 through the second outlet 32, further improving the homogeneity of the fluid mixture.

[0044] In this embodiment, there is no need to set up an external mechanical stirring structure. Based on the principle of fluid mechanics, the internal design of the tank 10 includes a flow guiding mechanism 40 with a flow splitting component 41, a first flow guiding component 42, and a second flow guiding component 43. This allows the fluid to naturally form eddies and turbulence during the flow process within the tank 10, thereby achieving uniform mixing. This simplifies the system design of the tank structure and reduces maintenance costs and equipment failure rate.

[0045] It is understood that the flow guiding mechanism 40 also includes a support frame 44, which can disperse the fluid pressure borne by the flow guiding mechanism 40 and prevent the first flow guiding component 42 and / or the second flow guiding component 43 from deforming or breaking due to fluid impact or vibration, thereby improving the stability of the overall structure.

[0046] In some embodiments, the inlet pipe 20 passes through the first guide component 42 and the second guide component 43 and is provided corresponding to the diversion component 41, and the first outlet 22 is located between the diversion component 41 and the first guide component 42.

[0047] In this embodiment, the inlet pipe 20 passes through the first guide component 42 and the second guide component 43, and the first outlet 22 is aligned with the diverting component 41 to reduce fluid turning resistance and ensure that the fluid is immediately distributed to the four sides of the receiving cavity 101 by the diverting component 41 after entering the tank 10, so as to form multiple natural turbulences and improve the mixing effect.

[0048] Please see Figure 4 In some embodiments, the first flow guiding component 42 includes a first flow guiding plate 421 and a second flow guiding plate 422. The first end of the first flow guiding plate 421 is connected to the liquid inlet pipe 20, the first end of the second flow guiding plate 422 is connected to the second end of the first flow guiding plate 421, and the second end of the second flow guiding plate 422 is spaced apart from the liquid inlet pipe 20, so that the first flow guiding component 42 forms a first flow guiding cavity 423 with a first opening.

[0049] In this embodiment, the first guide plate 421 and the second guide plate 422 cooperate to form a first guide cavity 423 with a first opening. The first guide cavity 423 is connected to the accommodating cavity 101 of the tank 10 through the first opening, so that the mixed fluid forming vortex and turbulence is further guided to the second guide component 43, forming a multi-stage guide effect.

[0050] In some embodiments, the first end of the first guide plate 421 has a first distance from the bottom of the tank 10, the second end of the first guide plate 421 has a second distance from the bottom of the tank 10, the second distance is greater than the first distance, and the second guide plate 422 forms a first angle with the first guide plate 421, the first angle being greater than 90°.

[0051] In this embodiment, the two ends of the first guide plate 421 are at different distances from the bottom of the tank 10, and the second guide plate 422 is set at an obtuse angle to the first guide plate 421, so that the first guide component 42 has a first opening at the top and a conical horn-shaped structure at the bottom. When the mixed fluid forming vortices and turbulence in the tank 10 comes into contact with the first guide component 42, it flows from the first opening along the conical structure of the second guide plate 422 into the first guide cavity 423, optimizing the guide path and improving the mixing effect.

[0052] In some embodiments, the second flow guiding component 43 includes a third flow guiding plate 431 and a fourth flow guiding plate 432. The third flow guiding plate 431 is connected to the liquid inlet pipe 20, and the fourth flow guiding plate 432 is arranged around the periphery of the third flow guiding plate 431. A first end of the fourth flow guiding plate 432 is connected to the third flow guiding plate 431, and a second end of the fourth flow guiding plate 432 is spaced apart from the first flow guiding component 42, so that the second flow guiding component 43 forms a second flow guiding cavity 433 with a second opening.

[0053] In this embodiment, the fourth guide plate 432 is arranged around the periphery of the third guide plate 431, forming a secondary guide coverage area in the first guide cavity 423, namely the second guide cavity 433. The second end of the fourth guide plate 432 is spaced apart from the first guide component 42 to form a flow port, so that the fluid can enter the second guide cavity 433 through the flow port and further discharge from the second guide cavity 433 to the container cavity 101 of the tank 10, thereby realizing multi-stage guide and mixing.

[0054] In some embodiments, the third guide plate 431 and the fourth guide plate 432 are connected at a second included angle, the second included angle being greater than or equal to 90°.

[0055] In this embodiment, the third guide plate 431 and the fourth guide plate 432 are designed at right angles or obtuse angles, so that the second guide component 43 has a larger included angle to reduce the resistance when the fluid passes through, and utilizes gravity to assist the fluid to flow naturally and further mix the fluid. At the same time, it avoids dead angles formed by sharp angle designs, which can lead to fluid blockage and reduce the risk of deposition.

[0056] In some implementations, such as Figure 2 and Figure 5 As shown, the outlet pipe 30 passes through the first guide member 42 and the second guide member 43, and is connected to the inlet pipe 20. At the end of the outlet pipe 30 connected to the inlet pipe 20, a second inlet 31 is formed on the side away from the diversion member 41, communicating with the second guide cavity 433. That is, the opening of the second inlet 31 faces the side of the second guide cavity 433 away from the first guide member 42.

[0057] Alternatively, the outlet pipe 30 passes through the first guide member 42 and the second guide member 43, and the end of the outlet pipe 30 near the connection with the inlet pipe 20 forms a second inlet 31 communicating with the second guide cavity 433, and the second inlet 31 is located on the wall of the second guide member 43, such as... Figure 1 As shown.

[0058] In this embodiment, when the second inlet 31 is located on the wall of the second guide member 43, the fluid passes through the second guide cavity 433 and smoothly enters the second inlet 31 along the wall of the second guide member 43, thereby exiting the receiving cavity 101, which can reduce flow resistance. Furthermore, the outlet pipe 30 is connected to the inlet pipe 20, and a second inlet 31 communicating with the second guide cavity 433 is formed on the side away from the diverting member 41. In other words, the connection between the second inlet 31 and the inlet pipe 20 forms an upward-facing semi-circular opening, further optimizing the flow path, allowing the fluid to exit the receiving cavity 101 through the upward-facing semi-circular opening within the second guide cavity 433, resulting in better mixing.

[0059] In some embodiments, the diversion component 41 has a first diversion end near the first drain port 22 and a second diversion end away from the first drain port 22, and the radial direction of the diversion component 41 gradually increases from the first diversion end to the second diversion end.

[0060] For example, the first branching end of the flow divider 41 near the first drain port 22 is pointed, and the radial direction gradually increases from the first branching end to the second branching end. The first branching end and the second branching end are connected by a smooth and gentle curved surface. With this configuration, when fluid with a certain flow velocity flows out from the first drain port 22 and comes into contact with the pointed first branching end, the pointed design of the first branching end can effectively split the fluid, causing it to naturally split into multiple streams along the curved surface of the flow divider 41, and forming multiple natural eddies and turbulences within the tank 10, further fully mixing the fluid within the tank 10 and facilitating fluid homogenization. It can be understood that the flow divider 41 includes, but is not limited to, cones and pyramids.

[0061] In some embodiments, the mixing device 100 further includes a protective layer covering the inner wall of the tank 10. Optionally, the protective layer may be an alloy, a non-metallic coating, a metallic plating, or a composite material to prevent the inner wall from being thinned or perforated by corrosion. It should be understood that the inlet pipe 20, the outlet pipe 30, and the flow guiding mechanism 40 should also be made of corrosion-resistant materials or at least wrapped with a protective layer of corrosion-resistant materials, so that the mixing device 100 can effectively resist the erosion of strong acids, strong alkalis, and organic solvents, improve equipment safety, and extend service life.

[0062] In some embodiments, the mixing device 100 further includes a power unit connected to the liquid outlet pipe 30 and used to extract at least a portion of the liquid from the receiving cavity 101 through the liquid outlet pipe 30. This configuration allows for stable and precise control of the extraction and delivery of the mixed fluid from the tank 10 to the outside, without relying on the height of the tank 10 or natural gravity for drainage, and adapts to complex tank layouts.

[0063] Please see Figures 6a to 6e , Figures 6a to 6e This is a 3D model rendering of the mixing device 100 in the first embodiment. The model uses passive scalars to perform transient analysis of the mixing process through simulations of static, turbulent, and single-phase flow. Figures 6a to 6d As shown, blue represents the concentration of the supplied liquid entering the tank 10 from the inlet pipe 20, and red represents the initial concentration of the original liquid in the tank 10 of the mixing device 100. It can be seen that the fluids in the mixing device 100 are mixed uniformly after approximately 5 minutes. Figure 6e As shown, it can be seen that after the liquid enters the tank 10 from the inlet pipe 20 and is discharged from the tank 10 through the outlet pipe 30, the flow direction of the liquid in the mixing device 100 indicates that the liquid forms natural eddies and turbulence in the tank 10, thereby achieving liquid mixing and homogenization.

[0064] Please see Figure 7 and Figure 8 , Figure 7 The mixing device 100 provided in the second embodiment of this application differs from the mixing device 100 in the first embodiment in that the flow guiding mechanism 40 includes a second flow guiding component 43. The second flow guiding component 43 forms a second flow guiding cavity 433 with a second opening on the side near the bottom of the tank 10. The second flow guiding cavity 433 is connected to the receiving cavity 101 through the second opening.

[0065] The inlet pipe 20 is connected to the second guide component 43 and passes through the second guide cavity 433 formed by the second guide component 43. The first outlet 22 of the inlet pipe 20 is located outside the second guide cavity 433. The outlet pipe 30 is connected to the second guide component 43, and the second inlet 31 is located inside the second guide cavity 433 and communicates with the second guide cavity 433.

[0066] It is understood that the specific structure and function of the second flow guiding component 43 can be referred to the relevant description in the first embodiment, and will not be repeated here.

[0067] like Figure 8 As shown, in this embodiment, a second flow guide 43 with a second opening is formed at the bottom of the tank 10. Fluid flows into the tank through the first drain port and forms a backflow effect at the bottom of the tank, thereby forming eddies and turbulence in the tank cavity, thus achieving a uniform mixing effect. Through a power component connected to the outlet pipe 30, the fluid is mixed again in the second flow guide cavity 433 formed by the second flow guide 43 and discharged from the container cavity 101 of the tank 10 through the second inlet 31 of the outlet pipe 30.

[0068] Please see Figure 9 and Figure 10 , Figure 9The mixing device 100 provided in the third embodiment of this application differs from the mixing device 100 in the aforementioned embodiment in that the flow guiding mechanism 40 includes a flow diversion component 41 and a second flow guiding component 43. The flow diversion component 41 is provided corresponding to the first drain port 22, and there is a first distance between the side of the flow diversion component 41 away from the bottom of the tank 10 and the first drain port 22.

[0069] It is understood that the specific structure, components and functions of the diversion component 41 and the second diversion component 43 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0070] like Figure 10 As shown, in this embodiment, a diversion component 41 is added. When the fluid flows out from the first drain port 22, it is guided by the diversion component 41 and forms a planar guide at the bottom of the tank 10, thereby flowing to the four sides of the receiving cavity 101. Furthermore, eddies and turbulence are formed in the receiving cavity 101, which improves the mixing efficiency.

[0071] Please see Figure 11 and Figure 12 , Figure 11 The mixing device 100 provided in the fourth embodiment of this application differs from the mixing device 100 of the previous embodiments in that the flow guiding mechanism 40 includes a first flow guiding component 42 and a second flow guiding component 43. The first flow guiding component 42 forms a first flow guiding cavity 423 with a first opening on the side away from the bottom of the tank 10. The first flow guiding cavity 423 is connected to the receiving cavity 101 through the first opening. The second flow guiding component 43 is disposed in the first flow guiding cavity 423 and forms a second flow guiding cavity 433 with a second opening. The first flow guiding cavity 423 is connected to the receiving cavity 101 through the first opening, and the second flow guiding cavity 433 is connected to the first flow guiding cavity 423 through the second opening. The second liquid inlet 31 is located in the second flow guiding cavity 433. The first opening faces the top of the tank 10, and the second opening faces the bottom of the tank 10.

[0072] It is understood that the specific structure, components and functions of the first flow guiding component 42 and the second flow guiding component 43 can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0073] like Figure 12 As shown, in this embodiment, the first guide component 42 and the second guide component 43 work together to form a mixture of vortex and turbulence. After the mixed fluid comes into contact with the first guide component 42, it flows into the second guide cavity 433 along the first guide cavity 423, realizing a multi-stage guide mode and significantly improving the mixing uniformity.

[0074] It is understood that the shape of the tank 10 can be cylindrical or other cylindrical shapes, such as rectangular prisms, and this application does not impose any limitations. It should also be understood that the mixing device 100 provided in this application is not only applicable to existing flow battery systems, such as electrolyte storage tanks, but also optimizes the internal structure of the tank to achieve more uniform mixing of the electrolyte, ensuring the stability and consistency of the battery reaction and extending the battery's lifespan. Furthermore, the mixing device 100 can also be applied in fields such as bioengineering, chemical engineering, agriculture, and food processing to ensure uniform mixing of fluids and improve fluid dispersibility and homogeneity.
