Description

Technical Field

[0001] This application relates to the field of fluid mixing technology, specifically a dual-liquid Venturi diluter. Background Technology

[0002] In many fields such as chemical engineering and environmental protection, liquid mixing and dilution are common process steps. Traditional liquid mixing methods often rely on agitators, pumps, or other power equipment to achieve fluid mixing. However, these methods are not only energy-intensive but also have limitations in terms of mixing efficiency and uniformity. Furthermore, for multi-component liquids requiring precise control of mixing ratios, traditional mixing methods often fall short.

[0003] To address these issues, the Venturi diluter was developed. It primarily utilizes the Venturi effect, where the flow rate increases and negative pressure is generated as fluid passes through a gradually narrowing pipe, thereby drawing in or mixing with other fluids. This physical phenomenon allows the Venturi diluter to achieve fluid mixing and dilution without an additional power source, thus significantly reducing energy consumption.

[0004] However, traditional Venturi diluters are often designed to be suitable only for mixing a single primary fluid and one or a limited number of secondary fluids. When it is necessary to mix multiple liquids, it may be necessary to use multiple Venturi diluters in series or parallel, which not only increases the complexity of the equipment but also reduces the flexibility of use.

[0005] Therefore, this application provides a dual-liquid Venturi diluter to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a dual-liquid Venturi diluter, which aims to solve the problems mentioned in the background art, such as the existing Venturi diluter design being singular and unable to flexibly cope with various liquid mixing needs.

[0007] To achieve the above objectives, this application provides the following technical solution: a dual-liquid Venturi diluter, comprising a mounting frame, a main inlet pipe disposed on the mounting frame, an inlet port opened at one end of the main inlet pipe for the main fluid to enter, branch pipes symmetrically disposed below the side of the mounting frame corresponding to the main inlet pipe and communicating with the main inlet pipe, Venturi tubes respectively disposed at the ends of the two branch pipes away from the main inlet pipe for drawing in other fluids to mix and dilute with the main fluid, and outlet pipes respectively disposed at the bottom end of the mounting frame and communicating with the two Venturi tubes respectively; Both branch pipes are fixedly connected to valves for shutting off or regulating the flow rate of the main fluid; The Venturi diluter also includes a fixing component located on the side of the branch pipe away from the valve for assembling and disassembling the main inlet pipe, branch pipe, Venturi tube, and mounting bracket. The combination design of two branch pipes, two Venturi tubes, and corresponding valves allows the diluter to easily handle the mixing and dilution needs of various liquids. Users can control the flow rate of different fluids by adjusting or shutting off the valves according to actual needs, thereby precisely adjusting the liquid mixing ratio. This flexibility allows the diluter to be widely used in chemical, environmental protection, and other fields, meeting the requirements of different working conditions and processes. Furthermore, by utilizing the Venturi effect through the Venturi tubes, the mixing and dilution of fluids not only improves mixing efficiency and ensures mixing uniformity but also eliminates the need for an additional power source, achieving energy savings. The combined design of the mounting bracket and fixing component makes the overall structure of the diluter compact, occupying little space, facilitating installation and use in limited working environments, and is also easy to disassemble and maintain.

[0008] Preferably, to facilitate the installation and use of the diluent, the mounting bracket includes a panel, connecting plates respectively fixed at the top and bottom of the panel, and mounting holes respectively opened on the two connecting plates for screws to pass through. The main inlet pipe, branch pipe, and venturi tube are located between the two connecting plates of the panel. Through the combined design of the panel, connecting plates, and mounting holes, the installation of the entire diluent becomes simple and clear. Users only need to insert screws into the corresponding mounting holes to fix the mounting bracket in the required position, and the diluent can be installed and used in any position.

[0009] Preferably, in order to facilitate the installation of the overall structure of the diluent, a first through hole is provided on the panel at the position corresponding to the branch pipe for the valve to pass through and connect, and a second through hole is provided on the connecting plate at the bottom of the panel for the two liquid outlet pipes to pass through and connect. The design of the first and second through holes avoids additional pipe connection steps, making the valve and liquid outlet pipes easier to connect and use.

[0010] Preferably, to facilitate fluid intake, mixing, and dilution, the Venturi tube includes a constriction tube disposed between the two corresponding connecting plates on the panel and connected to the branch tube at the end away from the main inlet tube to generate negative pressure; a throat tube connected to the constriction tube at the end away from the branch tube for other fluid intake and mixing with the main fluid; a secondary inlet tube connected to one side of the throat tube for other fluids to enter; and a diffusion tube connected to the throat tube and the outlet tube respectively for the diluted fluid to flow out. The negative pressure generated by the constriction tube allows other fluids to enter through the secondary inlet tube and mix and dilute with the main fluid in the throat tube, and finally flow to the outlet tube through the diffusion tube, avoiding the problems of fluid blockage or uneven mixing that may occur in traditional mixing methods.

[0011] Preferably, to ensure the outflow of other fluids and the diluted fluid, the diameter of the opening at one end of the constriction pipe near the throat is smaller than the diameter of the opening at the other end, and the diameter of the opening at one end of the diffusion pipe near the throat is smaller than the diameter of the opening at the other end. The smaller diameter of the opening at the end of the constriction pipe near the throat increases the flow velocity and decreases the static pressure of the main fluid as it passes through the constriction pipe, thereby creating a stronger negative pressure at the throat. This negative pressure effect is the core of the Venturi effect, which allows other fluids to be more effectively drawn in and mixed with the main fluid. The smaller diameter of the opening at the end of the diffusion pipe near the throat also allows the mixed fluid to gradually decelerate and increase its static pressure in the diffusion pipe, which helps the mixed fluid to flow out more stably.

[0012] Preferably, to facilitate the disassembly and assembly of the main inlet pipe, branch pipe, venturi tube, and mounting bracket, the fastener includes a positioning plate fixedly installed on the side of the branch pipe away from the panel corresponding to the first through hole, and bolts symmetrically arranged at both ends of the positioning plate. Both ends of the positioning plate are fixedly connected to the panel by the bolts. With this design, the user only needs to fix the positioning plate to the panel with bolts to easily disassemble and maintain the various components of the diluent.

[0013] This dual-liquid Venturi diluter, with its combination design of two branch pipes, two Venturi tubes, and corresponding valves, can easily meet the needs of mixing and diluting various liquids. Users can control the flow rate of different fluids by adjusting or shutting off the valves according to actual needs, thereby precisely adjusting the liquid mixing ratio. It can be widely used in chemical, environmental protection and other fields to meet the requirements of different working conditions and processes. This dual-liquid Venturi diluter uses the Venturi effect to mix and dilute fluids through a set Venturi tube, which not only improves mixing efficiency and ensures the uniformity of mixing, but also achieves energy saving without the need for an additional power source. This dual-liquid Venturi diluter features a compact overall structure with a small footprint due to the combination of mounting brackets and fasteners. It is easy to install and use in limited working environments, and is also easy to disassemble and maintain. Attached Figure Description

Detailed Implementation

[0016] 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, 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.

[0017] This embodiment provides a dual-liquid Venturi diluter, such as Figures 1-5 As shown, the Venturi diluter includes a mounting frame 1, a main inlet pipe 2 mounted on the mounting frame 1, an inlet port 21 at one end of the main inlet pipe 2 for the main fluid to enter, branch pipes 3 symmetrically arranged below the main inlet pipe 2 on one side of the mounting frame 1 and connected to the main inlet pipe 2, Venturi tubes 4 respectively located at the ends of the two branch pipes 3 away from the main inlet pipe 2 for drawing in other fluids to mix and dilute with the main fluid, and outlet pipes 5 respectively located at the bottom of the mounting frame 1 and connected to the two Venturi tubes 4; valves 6 for shutting off or regulating the flow rate of the main fluid are fixedly connected to the two branch pipes 3; the Venturi diluter also includes a fixing component 7 located on the side of the branch pipes 3 away from the valves 6 for assembling and disassembling the main inlet pipe 2, branch pipes 3, Venturi tubes 4 and mounting frame 1.

[0018] In use, firstly, install the main inlet pipe 2, branch pipes 3, venturi tubes 4, and outlet pipe 5 to the mounting bracket 1 using the fixed component 7. Then, install the diluent as a whole in the required position using the mounting bracket 1. Since the main inlet pipe 2 is connected to two branch pipes 3, and each of the two branch pipes 3 is connected to a venturi tube 4, the two venturi tubes 4 can be connected to different fluids according to usage requirements. When the main fluid enters the main inlet pipe 2 through the inlet port 21, one or more of the fluids can be opened. When both valves 6 are open, the main flow into the main inlet pipe 2 will flow into the branch pipe 3 where valve 6 is already open, and then through the branch pipe 3 to the venturi tube 4 connected to it. Under the effect of the venturi effect, the flow velocity of the main flow into the venturi tube 4 will increase and the static pressure will decrease, creating a negative pressure in the venturi tube 4. This negative pressure effect will cause other fluids connected to the venturi tube 4 to be drawn into the venturi tube 4 and mixed and diluted with the main flow. Finally, the mixed and diluted fluid will flow out through the outlet pipe 5 for use.

[0019] Specifically, the mounting bracket 1 includes a panel 11, connecting plates 12 respectively fixed at the top and bottom of the panel 11, and mounting holes 13 respectively opened on the two connecting plates 12 for screws to pass through. The main inlet pipe 2, the branch pipe 3 and the venturi pipe 4 are located between the two connecting plates 12 of the panel 11. After installing the main inlet pipe 2, branch pipe 3, venturi pipe 4 and outlet pipe 5 onto the panel 11 using the fixing component 7, place the panel 11 at the desired installation position. Then, through the mounting holes 13 provided on the connecting plate 12, screws can be inserted into the corresponding mounting holes 13 and tightened to install and use the diluent. Conversely, by loosening the screws and removing them from the mounting holes 13, the diluent can be moved.

[0020] To facilitate the installation of the overall structure of the diluent, a first through hole 111 is provided on the panel 11 at the position corresponding to the branch pipe 3 for the valve 6 to pass through and connect. A second through hole 121 is provided on the connecting plate 12 at the bottom of the panel 11 for the two liquid outlet pipes 5 to pass through and connect. The design of the first through hole 111 and the second through hole 121 avoids additional pipe connection steps, making the valve 6 and the liquid outlet pipe 5 easier to connect and use.

[0021] Furthermore, the Venturi tube 4 includes a contraction pipe 41 disposed between the two corresponding connecting plates 12 on the panel 11 and connected to the branch pipe 3 at the end away from the main inlet pipe 2 for generating negative pressure; a throat 42 connected to the end of the contraction pipe 41 away from the branch pipe 3 for drawing in other fluids and mixing with the main fluid; a secondary inlet pipe 44 connected to one side of the throat 42 for the entry of other fluids; and a diffusion pipe 43 connected to the throat 42 and the outlet pipe 5 respectively for the outflow of diluted fluids.

[0022] In addition, to ensure the intake of fluid and the outflow of diluted fluid, the diameter of the opening at the end of the contraction pipe 41 near the throat 42 is smaller than the diameter of the opening at the other end, and the diameter of the opening at the end of the diffuser pipe 43 near the throat 42 is smaller than the diameter of the opening at the other end. The smaller diameter of the opening at the end of the contraction pipe 41 near the throat 42 increases the flow velocity and decreases the static pressure of the main fluid when it passes through the contraction pipe 41, thereby creating a stronger negative pressure at the throat 42. This negative pressure effect is the core of the Venturi effect, which allows other fluids to be more effectively drawn in and mixed with the main fluid. The smaller diameter of the opening at the end of the diffuser pipe 43 near the throat 42 also increases the static pressure of the mixed fluid in the diffuser pipe 43, which helps the mixed fluid to flow out more stably. When one or both valves 6 are opened, the main fluid flows into the branch pipe 3 connected to the corresponding opened valve 6, and then into the contraction pipe 41 connected to it. At this time, as the inside of the contraction pipe 41 gradually narrows, the flow velocity of the main fluid increases. Then, according to Bernoulli's law, the increase in flow velocity will lead to a decrease in the pressure of the main fluid, thereby generating a negative pressure. Under the action of negative pressure, other fluids will be drawn into the throat pipe 42 through the auxiliary inlet pipe 44 and mixed with the main fluid to achieve dilution. The mixed and diluted fluid will then enter the diffusion pipe 43 and diffuse through the diffusion pipe 43, and finally flow out for use.

[0023] Furthermore, the fastener 7 includes a positioning plate 71 fixedly installed on the side of the branch pipe away from the panel 11 corresponding to the first through hole 111, and bolts 72 symmetrically arranged at both ends of the positioning plate 71. Both ends of the positioning plate 71 are fixedly connected to the panel 11 by bolts 72. After installing the main inlet pipe 2, branch pipe 3, venturi pipe 4, and outlet pipe 5, place the branch pipe 3 at the designated position on the panel 11. Then, pass the bolt 72 through the hole on the positioning plate 71 and screw the bolt 72 onto the panel 11 until it is tightened. The main inlet pipe 2, branch pipe 3, venturi pipe 4, and outlet pipe 5 can then be installed on the panel 11 for use. Conversely, by loosening the bolt 72 and unscrewing it from the panel 11, the main inlet pipe 2, branch pipe 3, venturi pipe 4, and outlet pipe 5 can be removed from the panel 11 for maintenance or replacement.

[0024] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
