Description

Technical Field

[0001] This application relates to the technical field of centralized liquid supply, and in particular to a high-speed fluid mixing and supply device. Background Technology

[0002] For scenarios requiring long-term, large-volume liquid supply, existing liquid supply systems generally adopt a ready-to-use approach. That is, different liquid raw materials are stored in liquid tanks, and when liquid supply is needed, the different liquid raw materials are mixed. After mixing, the mixture is sent directly to the liquid-using equipment without storage, such as clustered machine tool and lathe cutting coolant supply scenarios. In such scenarios, there are no strict requirements on the gas content in the mixed liquid.

[0003] Because the liquid supply system draws a single liquid raw material from the liquid tank into the mixer, the liquid itself has a high flow rate. Using a stirring blade to stir the liquid raw material will cause the liquid kinetic energy to be lost and the mixing effect will be poor. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this application provides a high-speed fluid mixing and supply device. In this embodiment, a velocity difference is generated between the direction of the highest-proportion original liquid flow and the direction of the lower-proportion original liquid flow by using a combination of a throttling orifice plate, a first variable diameter section, and a branch supply pipe. This velocity difference is used to mix the original liquid, thereby increasing the mixing effect and reducing the kinetic energy dissipation of the high-speed fluid.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A high-speed fluid mixing and supply device includes a main mixing pipe and a floor base, wherein the main mixing pipe is installed on the floor base;

The main mixing pipe includes a main inlet section, a first variable diameter section, and a first flow stabilizing section arranged sequentially in the direction from the main inlet end to the outlet end. A throttling orifice plate is provided inside the main mixing pipe. The throttling orifice plate is located between the main inlet section and the first variable diameter section. The inner and outer diameters of the end face of the first variable diameter section near the throttling orifice plate are the same as the inner and outer diameters of the main inlet section. The inner diameter of the first variable diameter section first increases and then decreases in the direction from the main inlet end to the outlet end. The inner and outer diameters of the end face of the first variable diameter section near the first flow stabilizing section are the same as the inner and outer diameters of the main inlet section.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application provides a high-speed fluid mixing and supply device, as shown in the attached document. Figure 2 It includes a floor base 200 for installation on a fixed mounting base such as the ground or a platform, and a main mixing pipe 100 for high-speed fluid mixing. In the assembled state, the floor base 200 is installed on a fixed mounting base, and the main mixing pipe 100 is installed on the floor base 200.

[0025] The main mixing tube 100 has a main inlet end 101 and an outlet end 102. Liquid enters from the main inlet end 101, is mixed in the main mixing tube 100, and is discharged from the outlet end 102.

[0026] The main inlet end 101 of the main mixing pipe 100 is provided with a main connector 103 for the liquid supply hose. The main connector 103 can be a flange, an extension pipe with external threads, etc. In the assembled state, the liquid supply hose with the highest proportion of the mixed liquid is connected here.

[0027] The main mixing pipe 100 includes a main inlet section 104, a first variable diameter section 105, and a first flow stabilizing section 106 arranged sequentially in the direction from the main inlet end 101 to the outlet end 102. The main inlet section 104, the first variable diameter section 105, and the first flow stabilizing section 106 are fixed in sequence to form the main mixing pipe 100. A throttling orifice plate 107 is provided inside the main mixing pipe 100. The throttling orifice plate 107 is located between the main inlet section 104 and the first variable diameter section 105. The inner and outer diameters of the end face of the first variable diameter section 105 near the throttling orifice plate 107 are the same as the inner and outer diameters of the main inlet section 104. The inner diameter of the first variable diameter section 105 first increases and then decreases in the direction from the main inlet end 101 to the outlet end 102. The inner and outer diameters of the end face of the first variable diameter section 105 near the first flow stabilizing section 106 are the same as the inner and outer diameters of the main inlet section 104.

[0028] At least one branch liquid supply pipe 108 is fixedly connected to the first reducing section 105. In the assembled state, the liquid supply hose with a lower proportion of the mixed liquid is connected to the branch liquid supply pipe 108. Of course, the branch liquid supply pipe 108 may also have connecting parts such as flanges and external threads.

[0029] The branch supply pipe 108 is connected to the main mixing pipe 100, and the angle between the central axis of the branch supply pipe 108 and the central axis of the main mixing pipe 100 is directed toward the main inlet end 101.

[0030] The following section will provide further details based on specific usage scenarios.

[0031] First, it is necessary to understand that, as shown in the appendix Figure 1 As shown, the high-speed fluid mixing and supply device is installed in clustered factory areas where raw materials are frequently used. It is installed according to needs and will not be easily modified after installation. When installing the high-speed fluid mixing and supply device, the operator can adjust the number of branch supply pipes 108 according to the type and quantity of raw materials required.

[0032] In use, the main mixing pipe 100 and the floor base 200 are already in the assembled state. In the assembled state, the liquid supply hose with the highest proportion of the mixed liquid is fixed to the main connector 103, the liquid supply hose with the lower proportion of the mixed liquid is connected to the branch supply pipe 108, the main outlet pipe is fixed to the outlet end 102 of the main mixing pipe 100, and the supply hoses for connecting the liquid-using equipment are connected to the main outlet pipe.

[0033] When liquid supply is required, the raw liquid with the highest proportion enters the main mixing pipe 100 from the main inlet 101, while the liquid with a lower proportion in the mixed liquid enters the main mixing pipe 100 through the branch supply pipe 108.

[0034] Upon closer inspection, because the orifice plate 107 reduces the inner diameter of the raw liquid flow channel, it partially blocks the raw liquid flow channel. As a result, the raw liquid with the highest proportion enters the main liquid inlet 104 and becomes turbulent after passing through the orifice plate 107. A static pressure zone is formed on the edge of the orifice plate 107 away from the main liquid inlet 101. The flow velocity in the static pressure zone is low, and the raw liquid with the highest proportion loses a large amount of kinetic energy here.

[0035] The raw liquid with a lower component proportion enters the first variable diameter section 105 through the branch supply pipe 108. The inner diameter of the first variable diameter section 105 is generally larger than that of the main inlet section 104. This expands the static pressure zone on the side edge of the throttling orifice plate 107 away from the main inlet end 101. After the high-speed raw liquid with a lower component proportion enters the static pressure zone, it drives the raw liquid with the highest proportion in the static pressure zone to leave. As subsequent high-speed raw liquid with a lower component proportion continues to flow in, the static pressure zone shifts towards the middle of the main mixing pipe 100, so that the raw liquid with the highest proportion in the static pressure zone is close to the high-speed flow part in the middle of the main mixing pipe 100. In this way, the high-speed raw liquid with a lower component proportion does not immediately collide with the rigid blocking part after entering the main mixing pipe 100, reducing the kinetic energy dissipation of the high-speed raw liquid with a lower component proportion. The static pressure zone is compressed and extended towards the middle of the main mixing pipe 100 by the impact of the high-speed raw liquid with a lower component proportion, which significantly reduces the kinetic energy dissipation of the raw liquid with the highest proportion.

[0036] When the highest proportion of the original liquid passes through the orifice plate 107, turbulence will occur, and a velocity difference will appear in the original liquid flow. Since the angle between the central axis of the branch supply pipe 108 and the central axis of the main mixing pipe 100 is towards the main inlet end 101, there is an angle difference between the original liquid with a smaller proportion and the original liquid with the highest proportion. In this way, the angle difference between the original liquid flows, the velocity difference in the original liquid with the highest proportion, and the strong turbulence tendency after passing through the orifice plate 107 will not allow the original liquids to be fully mixed, which will significantly improve the mixing effect.

[0037] The mixed original liquid passes through the first flow stabilizing section 106 with a uniform inner diameter for flow stabilization, reducing some eddies and turbulence, so that the internal flow velocity of the mixed original liquid tends to be uniform, and then it can be discharged through the liquid outlet 102.

[0038] In summary, the embodiments of this application use a combination of a throttling orifice plate 107, a first variable diameter section 105, and a branch liquid supply pipe 108 to create a velocity difference between the direction of the highest proportion of the original liquid flow and the direction of the direction of the lowest proportion of the original liquid flow. The original liquid is mixed by using the velocity difference, which increases the mixing effect and reduces the kinetic energy dissipation of high-speed fluids.

[0039] In one feasible specific implementation of the embodiments of this application, refer to the appendix. Figure 3 The main mixing pipe 100 also includes a second variable diameter section 109 fixed to one end of the first flow stabilizing section 106 away from the first variable diameter section 105. The inner diameter of the middle part of the second variable diameter section 109 is smaller than the inner diameter of the first flow stabilizing section 106. By setting the second variable diameter section 109, the mixed liquid flow after the flow stabilization is made to form an internal velocity difference and local turbulence of the liquid again, thereby enhancing the mixing effect.

[0040] In some possible implementations of the embodiments of this application, refer to the appendix. Figure 4 A high-pressure gas inlet pipe 110 is fixedly connected to the second diameter-reducing section 109. In use, high-pressure gas can be introduced into the second diameter-reducing section 109 through the gas pipe 110. As the inner diameter of the second diameter-reducing section 109 decreases, the pressure at this point decreases. The incoming high-pressure gas is dispersed by the turbulent original liquid flow, forming small bubbles in the original liquid flow. As the original liquid flow continues to flow, the small bubbles move continuously in the original liquid flow to improve the mixing effect of the original liquid. It should be noted that the scenario of using high-pressure gas to assist mixing is only suitable for clustered machine tool and lathe cutting coolant supply scenarios. In this scenario, there are no strict requirements on the gas content in the mixed liquid. It is not suitable for scenarios with low tolerance for gas content in the liquid.

[0041] Based on this, a vent hole 111 is opened on the part of the gas pipe 110 inserted into the second diameter section 109. The setting of the vent hole 111 increases the degree of dispersion of gas in the direction of diffusion into the liquid. The vent hole 111 is also similar to the orifice plate 107 to increase the degree of turbulence when the original liquid flows through the vent hole 111, further increasing the mixing effect of the original liquid.

[0042] In one feasible implementation of this application, the main mixing pipe 100 further includes a second flow stabilizing section 112 fixedly connected to the end of the second variable diameter section 109 away from the first flow stabilizing section 106. The inner diameter of the second flow stabilizing section 112 remains unchanged, and the function of the second flow stabilizing section 112 is the same as that of the first flow stabilizing section 106. The mixed original liquid passes through the second flow stabilizing section 112 with a consistent and continuous inner diameter for flow stabilization, reducing some eddies and turbulence, so that the internal flow velocity of the mixed original liquid tends to be consistent, and then it can be discharged through the liquid outlet 102.

[0043] In one possible specific implementation of the embodiments of this application, refer to the appendix. Figure 4 The base 200 includes a base 201 and a support 202. The base 201 is fixed to the mounting foundation by bolts or other connectors. The support 202 is located on top of the base 201. The base 201 is used to fix the base to the mounting foundation. The main mixing pipe 100 is located on the support 202. The angle and position between the support 202 and the base 201 are adjustable. In this way, when the main mixing pipe 100 mixes liquid, the vibration generated will be released, so that the original liquid flow inside it will vibrate synchronously and further improve the mixing effect.

[0044] In some possible implementations of the embodiments of this application, the landing base 200 further includes an elastic pad 203. The elastic pad 203 is disposed between the support body 202 and the base body 201. The elastic pad 203 is elastic and its shape is adjustable. By disposing of the elastic pad 203, the position and angle between the support body 202 and the base body 201 can be adjusted.

[0045] The carrier 202 and the base 201 can be connected by bolts after drilling bolt holes. The bolts use elastic washers, and the diameter of the bolt hole is larger than the diameter of the bolt column, so that the position and angle between the carrier 202 and the base 201 can be finely adjusted.

[0046] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
