Technical Field
[0001] This invention relates to the field of air compression technology, specifically to a spiral air compressor. Background Technology
[0002] An air compressor is a device that converts mechanical energy into gas pressure energy, widely used in industrial production, construction engineering, medical equipment, and daily life. Its core working principle involves an electric motor or internal combustion engine driving internal components such as pistons, screws, or vanes to draw in and compress air, thereby increasing its pressure and density. The compressed air can be stored in an air tank for later use. Based on their structure and working principle, air compressors are mainly classified into reciprocating, screw, centrifugal, and vane types, each with its specific application scenarios and advantages. For example, reciprocating compressors are suitable for small-scale, high-pressure applications, while screw compressors are more suitable for large-scale, continuous air supply needs. The performance parameters of an air compressor mainly include discharge volume, discharge pressure, power, and efficiency, which directly affect its working effect and energy consumption.
[0003] While oil-lubricated screw air compressors are widely used in industrial applications, they have some significant drawbacks compared to rotary screw air compressors. During operation, oil-lubricated compressors require lubricating oil to cool and seal the rotor, inevitably leading to oil contamination in the compressed air. Even with high-efficiency filtration, trace amounts of oil may still remain in the compressed air, which is unacceptable for industries with extremely high air quality requirements, such as food, pharmaceuticals, and electronics.

[0022] like Figures 1-12 As shown, the present invention provides a technical solution: a spiral air compressor, including a frame 1 for fixing and supporting the device; Air compression mechanism 2 is used to compress the filtered air. By setting air compression mechanism 2, the filtered air can be compressed, thereby increasing the gas pressure to meet the needs of transportation or storage. The connecting mechanism 3 is used to guide the air compressed by the air compressor 2. By setting the connecting mechanism 3, the water required for air compression can be poured into the middle of the inner cavity of the air compressor 2, so that when the air compressor 2 is working, the screw can be lubricated by water, and the air compressed to a certain pressure can be discharged out of the inner cavity of the air compressor 2. The air intake mechanism 4 is used to filter the air and deliver it to the air compression mechanism 2. By setting the air intake mechanism 4, the external air can be absorbed by the force of the screw rotation during the operation of the air compression mechanism 2, so that the external air can enter the inner cavity of the air compression mechanism 2, thereby achieving the effect of saving energy. The cooling unit 6 is used to cool the compressed hot air, and the support frame 5 is fixedly connected to the outer surface of the cooling unit 6. By setting the cooling unit 6, the force of the screw rotation can be used to pressurize the water stored inside during the operation of the air compressor mechanism 2, so that the water enters the inner cavity of the air compressor mechanism 2 through the connecting mechanism 3, thereby achieving the cooling and lubrication of the screw, and cooling and separating the compressed air and water mixture. The air compression mechanism 2 is fixedly connected to the top of the frame 1, the connecting mechanism 3 is fixedly connected to the lower surface of the air compression mechanism 2, the air intake mechanism 4 is disposed on the upper surface of the air compression mechanism 2, the support frame 5 is fixedly connected to the surface of the frame 1, and the cooling unit 6 is fixedly connected to the surface of the frame 1 through the support frame 5.
[0023] The air compression mechanism 2 includes a compression box 21, which is fixedly connected to the top of the frame 1. A first partition frame 23 is fixedly connected to the inner wall of the compression box 21, and a second partition frame 24 is fixedly connected to the inner wall of the compression box 21 away from the first partition frame 23. A packaging box 22 is fitted onto the outer surface of the compression box 21 near the first partition frame 23, and a fixing frame 25 is fixedly connected to the outer surface of the packaging box 22. A stepper motor 26 is fixedly connected to the inner wall of the fixing frame 25, and a first rotating rod 27 is mounted on the output end of the stepper motor 26 via a coupling. By setting the first partition frame 23 and the second partition frame 24, a sealed space can be formed inside the compression box 21 while supporting the screw. The fixed frame 25 supports and fixes the stepper motor 26. By setting the stepper motor 26, the first rotating rod 27 can rotate after the power is connected and the switch is turned on. A first rotating column 28 is fixedly connected to the end of the first rotating rod 27. A first bearing 29 and a second bearing 212 are fixedly connected to both ends of the first rotating column 28, respectively. The outer ring of the first bearing 29 is fixedly connected to the inner wall of the first partition frame 23, and the outer ring of the second bearing 212 is fixedly connected to the inner wall of the second partition frame 24. A female threaded rod 211 is fixedly connected to the outer surface of the first rotating column 28. By setting the first bearing 29 and the second bearing 212, the first rotating column 28 can be limited, enabling it to rotate stably. The rotation further stabilizes the female screw 211. A first helical gear 210 is fitted on the outer surface of the first rotating column 28 near the first rotating rod 27. A second helical gear 216 meshes with the outer surface of the first helical gear 210. A second rotating column 214 is fixedly connected to the inner ring of the second helical gear 216. A third bearing 215 and a fourth bearing 218 are respectively fitted on both ends of the second rotating column 214. The outer ring of the third bearing 215 is fixedly connected to the inner wall of the first partition 23, and the outer ring of the fourth bearing 218 is fixedly connected to the inner wall of the second partition 24. A male screw 217 is fixedly connected to the outer surface of the second rotating column 214, and the male screw 217 meshes with the female screw 211. A first gear 213 is fixedly connected to the end of the first rotating column 28 away from the first rotating rod 27. The first gear 213 is located on the outer surface of the compression box 21. By setting a first helical gear 210, when the first rotating column 28 and the first rotating rod 27 rotate due to the rotation of the output end of the stepper motor 26, the first helical gear 210 can drive the second helical gear 216 to rotate, thereby causing the second rotating column 214 and the male screw 217 to rotate. The first helical gear 210 and the second helical gear 216 have the same number of rack teeth, so the first helical gear 210 and the second helical gear 216 rotate synchronously. By setting a third bearing 215 and a fourth bearing 218, the second rotating column 214 can generate stable rotation.By incorporating a male screw 217 and a female screw 211, which are the core components for gas compression, their helical teeth form a continuous, sealed chamber during rotation. As the screws rotate, the chamber volume gradually decreases, thus progressively compressing the intake air. The precise meshing of the male and female screws 217 not only ensures a highly efficient compression process but also reduces gas leakage, improving the overall efficiency of the compressor. Furthermore, the gap design between the screws allows water, necessary for lubrication, to enter, forming a lubricating film, reducing friction and wear, and simultaneously providing cooling and sealing.
[0024] The connecting mechanism 3 includes a first connecting box 31, which penetrates the lower surface of the compression box 21. The first connecting box 31 is located directly below the middle of the female screw 211. A blocking ring 32 is fixedly connected to the inner wall of the first connecting box 31. A partition rod 33 is fixedly connected to the inner wall of the first connecting box 31. A first limiting ring 34 is fixedly connected to the end of the partition rod 33.

The first blocking block 36 and the plug... The inner wall of the plug ring 32 is pressed and adapted. The outer surface of the first sliding rod 35 is fitted with a first spring 37. By setting a first connecting box 31 and placing it on the lower surface of the compression box 21 directly below the female screw 211, the water discharged from the top of the first connecting box 31 can flow into the gap between the male screw 217 and the female screw 211, thereby forming a lubricating film and reducing friction and wear. By setting a plug ring 32, it can cooperate with the first plug block 36, thereby preventing water from being discharged from the top of the first connecting box 31 when they are in contact. The first sliding rod 35 and the first spring 37 are positioned to create a vertical up-and-down movement effect at the inner ring of the first limiting ring 34, thereby ensuring that the first blocking block 36 is always in contact with the blocking ring 32, thus preventing backflow of liquid. The connecting mechanism 3 also includes a second connecting box 38, which penetrates the lower surface of the compression box 21. The second connecting box 38 is located directly below the end of the female screw 211 near the first gear 213. A vent plate 39 is fixedly connected to the inner wall of the second connecting box 38, and a second blocking block is slidably connected to the inner cavity of the vent plate 39. 310, a second spring 311 is fitted on the outer surface of the second blocking block 310. The bottom end of the second spring 311 is fixedly connected to the upper surface of the vent plate 39. The outer surface of the second blocking block 310 is squeezed and adapted to the inner wall of the second connecting box 38. By setting the vent plate 39, the second blocking block 310 can be limited, so that the second blocking block 310 can move vertically up and down. By setting the second spring 311, the second blocking block 310 can be pulled, so that the air in the cavity of the compression box 21 can only flow from the compression box 21 to the second connecting box 38.
[0025] The air intake mechanism 4 includes a transfer box 41, which is fixedly connected to the upper surface of the compression box 21.

A spiral rod 48 is fixedly connected to the end of the second rotating rod 46 away from the second gear 47. A connection port 49 is movably connected to the inner wall of the transfer box 41. A sealing ring 410 is fixedly connected to the outer surface of the port 49. The sealing ring 410 is pressed and adapted to the inner wall of the transfer box 41.

By setting a second gear 47, it can mesh with the first gear 213 when the first gear 213 rotates, so that the second rotating rod 46 can drive the screw rod 48 to rotate, thereby generating airflow in the inner cavity of the transfer box 41, thereby drawing outside air into the inner cavity of the transfer box 41, and then pouring it into the inner cavity of the third connecting box 413 through the telescopic tube 411 and the first connecting tube 412.
[0026] The cooling unit 6 includes a drainage mechanism 61, a cooling mechanism 62, and a pressurization mechanism 63. The drainage mechanism 61 includes a water tank 611, which is fixedly connected to the top of the support frame 5. A leak tank 612 extends through the lower surface of the water tank 611.

The end of the second connecting pipe 616 is fixedly connected to the lower surface of the first connecting box 31. The water tank 611 stores the water needed for screw lubrication. A leakage tank 612 allows water to flow in and out of the tank. A third blocking block 614 and a third sliding rod 613 change the leakage flow from the tank 611 during vertical movement. A third spring 615 generates elastic potential energy, ensuring the sliding rod 613 is always subjected to an upward compressive force. The cooling mechanism 62 includes a third connecting pipe 621, fixedly connected to the lower surface of the second connecting box 38.

The one-way valve 625 penetrates the upper surface of the water tank 611. By setting a heat dissipation pipe 622, the high temperature of the compressed air and water can be cooled. The heat dissipation pipe 622 is made of metal, which allows heat to dissipate quickly. By setting an exhaust port 623, the compressed air generated in the device can be discharged and collected. By setting a one-way valve 625, the water can only flow from the top to the bottom of the one-way valve 625 and will not flow in the opposite direction. The pressurization mechanism 63 includes a sixth bearing 631, which is fixedly connected to the lower surface of the compression box 21. A third rotating rod 632 is fixedly connected to the inner ring of the sixth bearing 631.

A fan blade 635 is fixedly connected to the end of the third rotating rod 632. A fourth connecting box 634 is fitted on the outer surface of the fan blade 635. A fifth connecting pipe 636 passes through the lower surface of the fourth connecting box 634, and the end of the fifth connecting pipe 636 passes through the water tank 611. By setting the third gear 633, it can mesh with the first gear 213, so that when the first gear 213 rotates, it drives the third rotating rod 632 and the fan blade 635 to rotate, thereby allowing gas to enter the inner cavity of the fourth connecting box 634.And finally enters the inner cavity of the water tank 611 through the fifth connecting pipe 636.
[0027] Working principle: During use, the operator connects the stepper motor 26 to the power supply and turns on the switch, causing the first rotating rod 27 to drive the first rotating column 28 to rotate. During the rotation of the first rotating column 28, the first gear 213 will rotate as well. Since the second gear 47 meshes with it, the second gear 47 drives the second rotating rod 46 and the screw rod 48 to rotate. When the screw rod 48 rotates, a suction force is generated in the inner cavity of the transfer box 41, which in turn allows outside air to enter the inner cavity of the transfer box 41 through the air intake box 42. Then, it enters the inner cavity of the compression box 21 through the guide tube 411, the first connecting tube 412, and the third connecting box 413. When the first helical gear 210 rotates with the first rotating column 28, it drives the second helical gear 216 and the male screw 217 to rotate, which in turn causes the male screw 217 and the female screw 216 to rotate. 1. The screws rotate synchronously, and the helical teeth of both screws form a continuous sealed chamber during rotation. As the screws rotate, the volume of the chambers gradually decreases, thereby gradually compressing the intake air. While the first gear 213 rotates, it drives the third gear 633 to rotate, which in turn causes the fan blade 635 to rotate and the airflow to enter the inner cavity of the water tank 611 through the fifth connecting pipe 636. The air pressure in the inner cavity of the water tank 611 increases, causing the water inside to flow into the inner cavity of the second connecting pipe 616 and finally spray into the inner cavity of the compression box 21. With the lubrication of the water flow, the friction generated by the rotation of the male screw 217 and the female screw 211 is reduced. Then, the compressed air and water vapor will be discharged into the inner cavity of the heat dissipation pipe 622 through the second connecting box 38. The compressed air is discharged from the exhaust port 623 and collected, while the water vapor will quickly condense and re-enter the inner cavity of the water tank 611.
