Description

Technical Field

[0001] This invention relates to the technical field of gas stations, and specifically to an intelligently controlled containerized maglev gas station. Background Technology

[0002] Existing air compressor stations widely use oil-injected screw compressors, oil-free screw compressors, or gear-driven centrifugal compressors as their core power equipment. However, each of these solutions has its own shortcomings in achieving both oil-free operation, high efficiency, and low maintenance.

[0003] Oil-injected screw compressors have significant drawbacks in terms of air quality and long-term maintenance costs. While the design is mature and requires relatively low initial investment, the need to inject lubricating oil into the working chamber during compression for sealing, cooling, and lubrication means that even with multi-stage oil-gas separation and precision filtration, it's impossible to reduce the oil mist and vapor content in the compressed air to an absolutely oil-free level. Therefore, they are unsuitable for applications with stringent requirements for compressed air cleanliness, such as those in the food, pharmaceutical, and electronics industries. Furthermore, the lubricating oil is prone to oxidation or emulsification and deterioration under high temperatures and moisture, leading to reduced lubrication capacity and accelerated wear on the rotor and bearings. Typically, core components of the compressor need to be replaced every 3 to 5 years. Combined with regular oil and filter replacements, the maintenance burden throughout its lifespan is extremely heavy.

[0004] While oil-free screw compressors can provide truly oil-free compressed air, they are significantly limited in terms of reliability and economy. These models rely on high-precision synchronous gears and strict clearance seals to achieve dry operation, requiring extremely high manufacturing and assembly tolerances. During operation, the thermal expansion and minute wear of the rotor can easily cause internal leakage, leading to a gradual decrease in volumetric efficiency. Key components such as gears, shaft seals, and bearings wear out quickly, typically requiring complete replacement of the entire compressor every 3 to 5 years, resulting in long downtime and high replacement costs. Furthermore, oil-free screw compressors are highly sensitive to the cleanliness of the intake air; if the pre-filter fails, solid impurities will enter and rapidly accelerate internal damage, resulting in a low overall cost-effectiveness.

[0005] Gear-speed centrifugal compressors are suitable for high-flow-rate continuous operation, but they present significant challenges in terms of adaptability and operational risks. These compressors typically maintain high efficiency only under stable loads above 80 m³ / min, and are highly susceptible to surge under low-flow-rate or frequent start-stop conditions. Complex anti-surge control systems are necessary to ensure equipment safety, increasing system complexity and cost. High-speed gearboxes and impellers are extremely sensitive to the cleanliness and sealing performance of the lubricating oil; contamination or seal failure can lead to severe damage to gears and bearings. The complex structure and difficult disassembly of these compressors necessitate major overhauls and replacement of core components every 8 to 10 years, resulting in the highest initial investment and lifecycle maintenance costs among the three options.

[0006] Based on this, the present invention provides an intelligently controlled container maglev gas station. Summary of the Invention

[0007] To address the problems mentioned in the background section, this invention provides an intelligently controlled containerized maglev air station that is frictionless, requires no lubricating oil, has higher compression efficiency, and produces 100% clean, oil-free compressed gas. Furthermore, each compression stage is cooled, achieving near-ideal isothermal compression, with the intake temperature at each stage reduced to below 38°C, optimizing the compression process and achieving maximum compression efficiency. The entire device requires no lubricating oil, the air compressor is frictionless and maintenance-free, and the model is suitable for all climates (it can be used directly outdoors).

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligently controlled containerized maglev air station, comprising a container body; a first water cooler, a second water cooler, and a third water cooler, all disposed within the container body; a first maglev centrifugal air compressor disposed on the first water cooler; and a second maglev centrifugal air compressor disposed on the third water cooler; wherein the first maglev centrifugal air compressor and the second maglev centrifugal air compressor cooperate to compress the gas four times, and the first, second, and third water coolers cooperate to cool the compressed gas.

[0009] Furthermore, the first magnetic levitation centrifugal air compressor has a first-stage compression unit and a second-stage compression unit; the second magnetic levitation centrifugal air compressor has a third-stage compression unit and a fourth-stage compression unit; the outlet of the first-stage compression unit is connected to the inlet of the first water cooler, the inlet of the first-stage compression unit is connected to an inlet pipe, the outlet of the first water cooler is connected to the inlet of the second-stage compression unit, the outlet of the second-stage compression unit is connected to the inlet of the second water cooler, the outlet of the second water cooler is connected to the inlet of the third-stage compression unit, the outlet of the third-stage compression unit is connected to the inlet of the third water cooler, the outlet of the third water cooler is connected to the inlet of the fourth-stage compression unit, and the outlet of the fourth-stage compression unit is connected to a drain pipe.

[0010] Furthermore, the ports of the pipes are arranged outside the housing.

[0011] Furthermore, the housing is equipped with an air filter unit group, and the inlet pipe is connected to the air filter unit group.

[0012] Furthermore, a door is provided on the side of the box.

[0013] Furthermore, the container maglev gas station also includes an AI control system, which is used to automatically control the container maglev gas station so that it can operate without human intervention.

[0014] Compared with existing technologies, the intelligent control container maglev gas station provided by this invention has the following beneficial effects:

[0015] When the first magnetic levitation centrifugal air compressor is running, the first-stage compression unit generates negative pressure, drawing in outside air through the inlet pipe, compressing it, and sending it to the first water cooler. The second-stage compression unit simultaneously generates negative pressure, drawing in and compressing the gas from the first water cooler, then discharging it into the second water cooler. The second magnetic levitation centrifugal air compressor then operates (the third and fourth-stage compression units start simultaneously). The third-stage compression unit draws in and compresses the gas from the second water cooler, then delivers it to the third water cooler. The fourth-stage compression unit draws in and compresses air from the third water cooler, finally supplying it to external equipment through the exhaust pipe. This design utilizes a magnetic levitation centrifugal air compressor, eliminating friction and the need for lubrication, resulting in higher compression efficiency and 100% clean, oil-free compressed gas. Furthermore, each stage of compression is followed by cooling, achieving near-ideal isothermal compression. The inlet temperature at each stage can be reduced to below 38°C, optimizing the compression process and achieving the highest compression efficiency. The entire unit requires no lubrication, the air compressor is frictionless and maintenance-free, and the model is suitable for all climates (it can be used directly outdoors).

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] As attached Figure 1 To be continued Figure 7 As shown:

[0028] This invention provides an intelligently controlled containerized maglev air station, comprising a container body 1, a first water cooler 2, a second water cooler 3, a third water cooler 4, a first maglev centrifugal air compressor 5, and a second maglev centrifugal air compressor 6; the first water cooler 2, the second water cooler 3, and the third water cooler 4 are all disposed within the container body 1; the first maglev centrifugal air compressor 5 is disposed on the first water cooler 2; and the second maglev centrifugal air compressor 6 is disposed on the third water cooler 4.

[0029] The first magnetic levitation centrifugal air compressor 5 and the second magnetic levitation centrifugal air compressor 6 work together to compress the gas four times, and the first water cooler 2, the second water cooler 3 and the third water cooler 4 work together to cool the compressed gas.

[0030] like Figures 3 to 7 As shown, the first magnetic levitation centrifugal air compressor 5 has a first-stage compression unit 7 and a second-stage compression unit 8;

[0031] The second magnetic levitation centrifugal air compressor 6 has a third-stage compression unit 9 and a fourth-stage compression unit 10;

[0032] The outlet of the first-stage compression unit 7 is connected to the inlet of the first water cooler 2. The inlet of the first-stage compression unit 7 is connected to an inlet pipe 11. The outlet of the first water cooler 2 is connected to the inlet of the second-stage compression unit 8. The outlet of the second-stage compression unit 8 is connected to the inlet of the second water cooler 3. The outlet of the second water cooler 3 is connected to the inlet of the third-stage compression unit 9. The outlet of the third-stage compression unit 9 is connected to the inlet of the third water cooler 4. The outlet of the third water cooler 4 is connected to the inlet of the fourth-stage compression unit 10. The outlet of the fourth-stage compression unit 10 is connected to a drain pipe 12.

[0033] Specifically, when the first magnetic levitation centrifugal air compressor 5 is running, the first-stage compression unit 7 generates negative pressure, draws in external air through the inlet pipe 11, compresses it, and sends it into the first water cooler 2; the second-stage compression unit 8 simultaneously generates negative pressure, draws in and compresses the gas in the first water cooler 2, and then discharges it into the second water cooler 3. The second magnetic levitation centrifugal air compressor 6 is running (the third-stage compression unit 9 and the fourth-stage compression unit 10 start simultaneously). The third-stage compression unit 9 draws in and compresses the gas in the second water cooler 3 and delivers it to the third water cooler 4; the fourth-stage compression unit 10 draws in and compresses air from the third water cooler 4, and finally supplies it to external equipment through the discharge pipe 12.

[0034] This design utilizes a magnetic levitation centrifugal air compressor, which is frictionless, requires no lubricating oil, has higher compression efficiency, and produces 100% clean, oil-free compressed gas. Furthermore, each compression stage is cooled, achieving near-ideal isothermal compression. The intake temperature at each stage can be reduced to below 38°C, optimizing the compression process and resulting in maximum compression efficiency. The entire unit requires no lubricating oil, the air compressor is frictionless and maintenance-free, and the model is suitable for all climates (it can be used directly outdoors).

[0035] It is worth noting that this invention provides an intelligently controlled container maglev gas station that achieves a pressure of 0.5-0.6 MPa through three-stage compression and 0.8-1.0 MPa through four-stage compression, meeting the gas needs of various high-end manufacturing industries such as electronics and semiconductors, mobile phone supply chain, automobile manufacturing, auto parts, biopharmaceuticals, high-end food and beverage, and fine chemicals.

[0036] Specifically, the ports of pipe 12 are located on the outside of housing 1, a design that facilitates connection to external devices.

[0037] like Figure 1 and Figure 2 As shown, the housing 1 is equipped with an air filter unit group 13, and the inlet pipe 11 is connected to the air filter unit group 13. The air is filtered by the air filter unit group 13 and then enters the inlet pipe 11, which can ensure the cleanliness of the compressed gas.

[0038] like Figure 1As shown, a door 14 is provided on the side of the container 1. The container 1 is a shipping container and is equipped with a door 14 to facilitate the inspection and maintenance of the equipment inside the container 1 by staff.

[0039] Specifically, the container maglev gas station also includes an AI control system. The AI ​​control system is used to automatically control the container maglev gas station so that it can operate without human intervention. By setting up the control system, the container maglev gas station can be automatically controlled by the control system to achieve unattended operation. The AI ​​control system can be adapted to any standard industrial controller to realize the start-stop and operation logic control of the electrical components in this invention. The control circuit of the controller can be implemented by those skilled in the art through simple programming, and the control method and circuit connection will not be explained in detail here.

[0040] Working principle and usage process of this invention:

[0041] When the container maglev air station is operating, external air is first filtered by air filter unit group 13 to remove impurities. The clean air is then drawn into the first-stage compression unit 7 through inlet pipe 11. The first maglev centrifugal air compressor 5 operates, and its first-stage compression unit 7 generates negative pressure and performs primary compression of the air. The compressed high-temperature gas is sent to the first water cooler 2 for cooling. Subsequently, the second-stage compression unit 8 simultaneously generates negative pressure, draws in the cooled gas from the first water cooler 2 for secondary compression, and then sends the compressed gas to the second water cooler 3 for further cooling. Next, the second maglev centrifugal air compressor 6 starts, and the third-stage compression unit 9 draws in air from the second water cooler 3 and performs tertiary compression. The compressed gas is then discharged into the third water cooler 4 for cooling. Finally, the fourth-stage compression unit 10 draws in air from the third water cooler 4 and performs quaternary compression. The compressed gas is then stably output through outlet pipe 12 for use by external equipment.

[0042] The entire process employs a four-stage compression and three-stage intermediate cooling method. Each stage of compression is followed by immediate cooling, ensuring that the intake air temperature at each stage can be reduced to below 38℃, achieving near-isothermal compression and significantly improving compression efficiency. Simultaneously, the magnetic levitation centrifugal air compressor has no mechanical friction and requires no lubricating oil, guaranteeing 100% clean and oil-free compressed gas, and the equipment is maintenance-free.

[0043] The gas station is equipped with an AI control system that automatically controls and intelligently adjusts the entire process, monitoring operating parameters such as pressure and temperature in real time, and automatically adjusting the air compressor speed and cooling conditions to achieve stable unattended operation. The containerized body is equipped with 14 doors for easy inspection and maintenance, and the entire unit is adaptable to all climates and can be used directly outdoors.
