[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] like Figures 1 to 2As shown, an embodiment of the present invention provides a flow-stabilizing pipe mixing device, which includes a pipe mixing assembly and a flow-stabilizing tank 2. The pipe mixing assembly includes a pipe body 1, and a liquid outlet channel 11 is provided on the side of the pipe body 1. The liquid outlet channel 11 is used to output the mixed liquid after being mixed by the pipe body 1. The flow stabilizer 2 is fitted onto the outside of the pipe body 1, and there is a gap between the inner wall of the flow stabilizer 2 and the outer wall of the pipe body 1 to form a liquid storage chamber 3. The liquid outlet channel 11 can be connected to the liquid storage chamber 3 so that the liquid flowing out of the liquid outlet channel 11 can enter the liquid storage chamber 3. With this configuration, liquids such as aqueous phase and organic phase can enter the pipe mixing assembly for mixing. The mixed liquid flows out of the liquid outlet channel 11 on the side of the pipe body 1 and enters the liquid storage chamber 3. The liquid in the liquid storage chamber 3 itself can buffer and stabilize the mixed liquid flowing out of the liquid outlet channel 11. It can be stabilized in the liquid storage chamber 3 before flowing out. It has both mixing and stabilizing functions. The flow stabilizer 2 is fitted onto the outside of the pipe body 1, and the gap between the two forms the liquid storage chamber 3 for stabilizing the flow. This reduces the layout of redundant pipes between the two and reduces the overall lateral space occupied by the two. It is suitable for working conditions with limited space and solves the problem of large space occupation of pipe mixing equipment and flow stabilizing equipment in related technologies.

[0035] Optionally, the outlet channel 11 can be located inside the storage chamber 3. For example, the outlet channel 11 can be located above the highest liquid level in the storage chamber 3, reducing the height difference between the outlet channel 11 and the liquid in the storage chamber 3, thus improving the flow stabilization effect. Alternatively, the outlet channel 11 can also be located above the flow stabilizing tank 2, reducing the mutual influence between the liquid flow in the outlet channel 11 and the liquid flow in the storage chamber 3, ensuring that the outlet channel 11 is always above the liquid surface in the storage chamber 3. After the bottom opening of the flow stabilizing tank 2 is fitted onto the pipe body 1, the flow stabilizing tank 2 and the pipe body 1 can be connected by welding or bonding.

[0036] In some embodiments, the liquid outlet channel 11 is located above the flow stabilizer 2, and the flow stabilizer 2 is provided with an opening 21 above it. The liquid flowing out of the liquid outlet channel 11 can enter the flow stabilizer 2 through the opening 21. With this configuration, the opening 21 can serve as a clearance channel for the liquid flowing out of the liquid outlet channel 11 to enter the flow stabilizer 2. An open opening can be formed above the flow stabilizer 2, and the liquid flowing out of the liquid outlet channel 11 can fall directly into the opening 21, which facilitates the liquid flowing out of the liquid outlet channel 11 to fall smoothly by its own gravity.

[0037] In some embodiments, the pipe mixing assembly further includes a bend 4, the first end of which is connected to the liquid outlet channel 11, and the second end is connected to the top of the flow stabilizer 2 and connected to the liquid storage chamber 3. That is, after the bend 4 is connected to the liquid outlet channel 11, it can be tilted downward or bent downward to connect to the liquid storage chamber 3, which facilitates the downward flow of water along a preset path, making the water flow more regular.

[0038] In this embodiment, the flow cross-sectional size of the bend 4 gradually increases from the first end to the second end, so that the bend 4 can form a diffuser-type gradually expanding pipe structure. By gradually expanding the flow cross-section, the water flow velocity is reduced, and kinetic energy is converted into pressure energy to reduce turbulence.

[0039] The diffusion angle of the bend 4 can be, but is not limited to, 7° to 12° to avoid water flow separation.

[0040] Alternatively, the distance between the inner wall of the flow stabilizer 2 and the outer wall of the pipe 1 gradually increases from top to bottom. Similarly, this enables the liquid storage chamber 3 to form a diffusion-type gradually expanding pipe structure. By gradually expanding the flow cross section, the water flow velocity is reduced, and kinetic energy is converted into pressure energy to reduce turbulence.

[0041] like Figures 1 to 2 As shown, in some embodiments, a flow stabilizer 6 is provided in the liquid storage chamber 3. The flow stabilizer 6 is located below the liquid outlet channel 11. The extension direction of the flow stabilizer 6 forms an angle with the extension direction of the pipe body 1. That is, the flow stabilizer 6 can be horizontally mounted below the liquid outlet channel 11. After the mixed liquid flows out from the liquid outlet channel 11, it can fall onto the flow stabilizer 6. The flow stabilizer 6 can buffer the water flow, reduce the impact of the water flow, and facilitate the reduction of turbulence of the mixed liquid entering the liquid storage chamber 3.

[0042] The flow stabilizer 6 can be connected to the inner wall of the flow stabilizer 2 and / or the outer wall of the tube 1, and can be supported below the liquid outlet of the second end of the opening 21 or the bend 4.

[0043] In this embodiment, the flow stabilizing plate 6 is provided with multiple flow stabilizing holes. These holes can divide the large flow of mixed liquid entering through the opening 21 into multiple smaller flows, uniformly distributing the flow velocity and reducing turbulence within the storage chamber 3. Optionally, the multiple flow stabilizing holes can be arranged in a matrix on the flow stabilizing plate 6.

[0044] Optionally, the flow stabilizer 6 can also be designed as a spiral plate structure. The spiral plate structure is arranged around the pipe body 1 and extends from top to bottom. After the mixed liquid at the opening 21 falls onto the spiral plate structure, the spiral plate structure not only reduces the impact force of the mixed liquid on the liquid surface below, but also allows the mixed liquid to flow down in a spiral path and flow into the liquid storage chamber 3 in a transverse flow, further improving the buffering and flow stabilization effect. The spiral plate structure can be designed as a half circle, a full circle, or multiple circles.

[0045] In some embodiments, an overflow channel 22 is provided on the side of the flow stabilizing tank 2. The height of the overflow channel 22 is lower than that of the liquid outlet channel 11. With this configuration, the mixed liquid in the liquid outlet channel 11 flows out into the flow stabilizing tank 2 for flow stabilization, and then the stabilized liquid overflows out of the overflow channel 22. The overflow channel 22 can limit the maximum liquid level of the flow stabilizing tank 2, avoid the liquid level from being too high due to fluctuations in the inlet flow rate or downstream blockage, make the water flow velocity uniform, and reduce turbulence or short-circuiting. When the liquid outlet flow rate of the liquid outlet channel 11 of the pipe body 1 suddenly increases, the overflow channel 22 can also directly discharge the excess liquid, reducing the situation where the flow stabilizing tank 2 is overloaded and affects the flow stabilization effect.

[0046] In some embodiments, the flow stabilizing pipe mixing device further includes a clarification chamber 5. In the vertical direction, an overflow channel 22 is provided near the top of the flow stabilizing tank 2. The overflow channel 22 is connected to the clarification chamber 5. The mixed liquid in the oil storage chamber can overflow from the surface, which can effectively carry away suspended light particles and other impurities, reducing their accumulation in the flow stabilizing tank 2. The flow stabilizing tank 2 can also separate large particle impurities. Moreover, the mixed liquid in the flow stabilizing tank 2 can flow out of the clarification chamber 5 by its own gravity for clarification and fine treatment, making the effluent clearer.

[0047] In some embodiments, the tube body 1 has at least two liquid inlet channels 12, which are located below the flow stabilizer 2. This reduces interference between the liquid inlet channels 12 and the flow stabilizer 2. Different liquid inlet channels 12 can enter their respective liquid inlet channels 12. Multiple liquids flow and mix from bottom to top in the tube body 1, increasing the mixing efficiency. The fully mixed liquid then flows downward from the liquid outlet channel 11 at the top of the tube body 1 into the liquid storage chamber 3, improving the mixing effect and reducing space occupation.

[0048] In some embodiments, the cross-section of the pipe body 1 is circular, and the cross-section of the flow stabilizing tank 2 is also circular. The flow stabilizing tank 2 is coaxially arranged with the pipe body 1, forming an annular liquid storage cavity 3. This allows the mixture to diffuse uniformly in a ring along the circumferential direction of the outer wall of the pipe body 1, reducing dead zones or short-circuiting phenomena caused by rectangular or eccentric structures. Circumferential symmetry enables the mixture to have a uniform velocity or pressure gradient, reducing local turbulence and forming a low-shear steady flow.

[0049] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
