Description
Technical Field
[0001] This utility model belongs to the field of gas mixing technology, and in particular relates to a skid-mounted low-pressure pipeline gas booster mixing device. Background Technology
[0002] Gas mixing refers to the process of mixing two or more different gases in a precise ratio according to specific needs. It has a wide range of applications in many industrial fields, such as chemical, electronic and food processing. Through professional gas mixing equipment, the input of each gas is precisely controlled by means of pressure difference, flow control and other technologies to obtain a mixed gas with stable composition and in compliance with standards.
[0003] Conventional binary gas mixing equipment requires an inlet pressure greater than 0.6 MPa. Mixing cannot be performed when the pressure is lower than this value. The conventional approach is to reduce the pressure to the appropriate level after the liquid gas vaporizer before mixing, and then supplying the gas to the workshop. If the workshop is far from the gas station, the cost of laying pipelines is high. Moreover, pressurized mixing equipment usually requires a lot of on-site assembly work, involving the connection and commissioning of numerous pipelines and equipment. Therefore, there is a need for a skid-mounted low-pressure pipeline gas pressurized mixing equipment. The skid-mounted design shortens the installation time and improves flexibility. Furthermore, with the pneumatic booster pump, gas buffer tank, and gas proportioning cabinet working together, it can efficiently pressurize, mix, and transport the gas, ensuring the stability and accuracy of gas pressurized mixing. Summary of the Invention
[0004] The purpose of this invention is to provide a skid-mounted low-pressure pipeline gas booster and mixing device. The skid-mounted design shortens the installation time and improves flexibility. Furthermore, the pneumatic booster pump, gas buffer tank, and gas proportioning cabinet work together to efficiently boost, mix, and transport the gas, ensuring the stability and accuracy of gas booster and mixing, thereby solving the aforementioned technical problems.

[0012] In the following description, embodiments of the skid-mounted low-pressure pipeline gas booster mixing equipment of the present invention will be described with reference to the accompanying drawings.
[0013] Figure 1-5 This invention illustrates a skid-mounted low-pressure pipeline gas booster mixing device according to an embodiment of the present invention. It includes a skid-mounted base 1. Two gas buffer tanks 2 are fixedly installed on the right side of the top of the skid-mounted base 1. Pneumatic booster pumps 3 are fixedly installed at both the front and rear ends of the right side of the top of the skid-mounted base 1. The inlet ends of the two pneumatic booster pumps 3 are connected to gas pressure pipelines 4, and the outlet ends of the pneumatic booster pumps 3 are connected to gas supply pipes 5. The end of the gas supply pipe 5 furthest from the pneumatic booster pumps 3 is connected to the inlet end of the gas buffer tanks 2. The outlet of tank 2 is connected to a gas supply pipe 6. The end of the gas supply pipe 6 away from the gas buffer tank 2 is connected to the gas proportioning cabinet 7. The surface of the gas supply pipe 5 is connected to a gas pipeline 11 through a tee fitting. Leveling components 8 are provided at the four corners of the bottom of the skid-mounted base 1. The leveling components 8 include a rotatable wheel frame 81 installed at the bottom of the skid-mounted base 1. A roller 82 is rotatably connected to one side of the wheel frame 81. A leveling foot 83 is slidably connected to the inner cavity of the wheel frame 81. A rotating wheel is rotatably connected to the top of the inner cavity of the wheel frame 81. The bottom of the moving part 84 and the rotating part 84 is fixedly connected to a threaded rod 85. The leveling foot 83 is threadedly connected to the surface of the threaded rod 85. Through the setting of the leveling assembly 8, the cooperation of the wheel frame 81 and the roller 82 gives the skid base 1 strong mobility, which is conducive to the user moving the skid base 1 into place for assembly and connection of relevant lines and pipes. At the same time, with the cooperation of the rotating part 84 and the threaded rod 85, the leveling foot 83 is threadedly pushed in, thereby making the leveling foot... The height adjustment of 83 can control the flatness and installation position of the skid base 1. The front and rear sides of the inner cavity of the wheel frame 81 are integrally formed with limit blocks 9. The front and rear sides of the leveling foot 83 are provided with limit grooves 10. The limit grooves 10 are slidably connected to the surface of the limit blocks 9. Through the cooperation of the limit grooves 10 and the limit blocks 9, the leveling foot 83 plays a limiting and guiding role, so that the leveling foot 83 always keeps vertical up and down movement, ensuring that the leveling foot 83 can be pushed forward stably.
[0014] Working Principle: In use, this invention first moves the skid-mounted base 1 to the designated installation position using hoisting equipment. Then, the rollers 82 and wheel frame 81 provide a degree of mobility for the skid-mounted base 1, allowing the user to assemble relevant power supplies, pipes, or control components. After assembly, the user uses a pry bar to move the rotating component 84. During rotation, the rotating component 84 drives the threaded rod 85 to rotate. The threaded rod 85, through its surface threads, pushes the leveling foot 83 downwards, generating a reverse supporting force on the wheel frame 81. This causes the surface of the rollers 82 to disengage from the ground. Simultaneously, the height of the leveling foot 83 can be adjusted according to different positions, enabling the leveling and calibration of the skid-mounted base 1. Subsequently, the gas to be mixed is supplied to the inner cavity of the gas supply pipe 5 through the gas pipeline 11, while the pneumatic pressure pipeline 4 supplies power gas to the inner cavity of the pneumatic booster pump 3. This causes the pneumatic booster pump 3 to pressurize the gas in the inner cavity of the gas supply pipe 5 and deliver it to the inner cavity of the gas buffer tank 2. The gas is stabilized and buffered by the air bladder inside the gas buffer tank 2. The buffered gas enters the inner cavity of the gas mixing cabinet 7 from the inner cavity of the gas supply pipe 6 for gas mixing. The mixed gas is then delivered to the gas-using equipment through the pipeline. During the process, the gas ratio is analyzed online by a gas analyzer. If the gas ratio does not meet the mixing requirements, the PLC controller issues a control command and simultaneously controls the solenoid valve to close to prevent gas backflow. At the same time, the audible and visual alarm sounds to remind technicians to intervene.
[0015] In summary, this skid-mounted low-pressure pipeline gas booster mixing equipment, through the combined use of the skid-mounted base 1 and the leveling component 8, positions the equipment on top of the skid-mounted base 1. Simultaneously, with the combined use of the pneumatic booster pump 3, the gas buffer tank 2, and the gas proportioning cabinet 7, the gas is boosted, mixed, and transported, thus achieving the purpose of rapid skid-mounted assembly and eliminating the need for laying long-distance pipelines.
