Description

Technical Field

[0001] This utility model relates to the field of quaternary pump technology, specifically a quaternary pump structure for liquid transportation. Background Technology

[0002] In numerous industries such as pharmaceutical manufacturing, chemical production, and analytical testing, the precise mixing and efficient delivery of multi-component liquids are crucial for ensuring product quality, improving production efficiency, and guaranteeing the accuracy of experimental results. Quaternary pumps, as highly efficient and precise devices specifically designed for the delivery and mixing of multi-component liquids, have found widespread application in these fields due to their unique advantage of being able to handle four different liquids simultaneously.

[0003] Traditional quaternary pump structures have gradually revealed numerous problems in practical applications. On the one hand, because liquids inevitably come into contact with air during transport, air bubbles are often introduced. The presence of these bubbles interferes with the accurate measurement of liquid flow, causing deviations between the actual transport ratio of each component and the set value, thus severely affecting transport accuracy and mixing effect. On the other hand, traditional quaternary pumps struggle to achieve thorough and uniform mixing of the four liquids, resulting in uneven distribution of components in the reaction system, reducing product yield and quality. Furthermore, traditional quaternary pumps are prone to flow fluctuations and pressure instability during long-term continuous operation, severely impacting the continuity and stability of production. Therefore, a quaternary pump structure for liquid transport is proposed. Utility Model Content

[0026] Example

[0027] Please see Figures 1-5 This utility model provides a technical solution: a quaternary pump structure for liquid transportation, including a transportation component 20, which includes a connecting pipe 21, an air extraction chamber 22, a degassing membrane 23, a mounting base 24, a proportional valve 25, a mixing chamber 26, a spiral blade 27, a high-pressure pump 28, a transportation pipe 29, a housing 210, an elastic metal diaphragm 211, and a diversion pipe 212;

[0028] An air extraction chamber 22 is provided outside the connecting pipe 21. Four connecting pipes 21 are evenly installed on the mounting base 24. A micro vacuum pump is installed on the top of the air extraction chamber 22. A degassing membrane 23 is fixedly connected to the inner wall of the connecting pipe 21. A proportional valve 25 is installed on the connecting pipe 21. One end of the connecting pipe 21 is connected to a mixing chamber 26. A spiral blade 27 is fixedly connected to the inner wall of the mixing chamber 26. A high-pressure pump 28 is installed at the bottom of the mixing chamber 26. A delivery pipe 29 is connected to one side of the high-pressure pump 28. One end of the delivery pipe 29 is connected to a housing 210. An elastic metal diaphragm 211 is fixedly connected to the inner wall of the housing 210. A diverter pipe 212 is connected to the bottom of the housing 210. The degassing membrane 23 plays a role in gas-liquid separation during the air extraction process. Four different liquids are input through the four connecting pipes 21 respectively. The flow rate of each liquid is controlled by the proportional valve 25 to ensure the accurate delivery ratio of each component liquid. As the liquid flows through connecting pipe 21, the suction chamber 22 works in conjunction with a micro vacuum pump to remove air bubbles, improving the accuracy and stability of liquid delivery. Subsequently, the four liquids enter mixing chamber 26, where spiral blades 27 enhance the turbulence of the liquid flow, ensuring thorough mixing of the components and improving mixing uniformity. The mixed liquid is then pressurized by high-pressure pump 28 and enters housing 210 through delivery pipe 29. Elastic metal diaphragm 211 buffers pressure fluctuations, ensuring stable output liquid pressure. Finally, the liquid is split through diversion pipe 212, flowing into outlet pipe 213 and waste liquid pipe 214 respectively. Electric valve 215 controls the liquid flow direction, achieving precise liquid delivery and waste liquid discharge. Throughout the process, controller 12 monitors and controls the operating status of each component in real time, ensuring stable operation of the quaternary pump structure. Elastic metal diaphragm 211, as a pressure compensation element, effectively absorbs pulses and stabilizes the output pressure, while maintaining a seal between elastic metal diaphragm 211 and housing 210.

[0029] In this embodiment, specifically: the outer wall of the diversion pipe 212 is connected to the liquid outlet pipe 213, which is used to deliver the mixed liquid.

[0030] In this embodiment, specifically: the outer wall of the diversion pipe 212 is connected to a waste liquid pipe 214, which is used to discharge excess waste liquid.

[0031] In this embodiment, specifically: an electric valve 215 is installed on the liquid outlet pipe 213 and the waste liquid pipe 214, and the opening and closing of the liquid outlet pipe 213 and the waste liquid pipe 214 are controlled by the electric valve 215.

[0032] In this embodiment, specifically: the suction chamber 22 is fixedly connected to the top of the mounting base 24, the suction chamber 22 is kept sealed, and the micro vacuum pump generates negative pressure inside the suction chamber 22 when it is working.

[0033] In this embodiment, specifically: the conveying component 20 is provided with a housing component 10, which includes an outer shell 11 and a controller 12. The controller 12 is mounted on the front surface of the outer shell 11, and the front surface of the controller 12 is equipped with a display screen and operation buttons so that the user can operate the controller 12.

[0034] In this embodiment, specifically: the mounting base 24 is fixedly connected to the inner wall of the outer casing 11.

[0035] In this embodiment, specifically: the controller 12 is electrically connected to the proportional valve 25 and the electric valve 215, and the controller 12 controls the working state of the proportional valve 25 and the electric valve 215.

[0036] Working principle or structural principle: In use, four different liquids are input through four connecting pipes 21, and the flow rate of each liquid is controlled by a proportional valve 25 to ensure accurate delivery ratio of each component. As the liquid flows through the connecting pipes 21, the suction chamber 22 works in conjunction with a micro vacuum pump to remove air bubbles, improving the accuracy and stability of liquid delivery. Subsequently, the four liquids enter the mixing chamber 26, where a spiral blade 27 enhances the turbulence effect, allowing the components to mix thoroughly and improving mixing uniformity. The mixed liquid is pressurized by a high-pressure pump 28 and enters the housing 210 through a delivery pipe 29. An elastic metal diaphragm 211 buffers pressure fluctuations, ensuring stable output liquid pressure. Finally, the liquid is split through a diversion pipe 212, entering the outlet pipe 213 and the waste liquid pipe 214 respectively. An electric valve 215 controls the flow direction of the liquid, achieving precise liquid delivery and waste liquid discharge. Throughout the process, the controller 12 monitors and controls the working status of each component in real time to ensure the stable operation of the quaternary pump structure.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
