Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to an air compressor specifically designed for laser cutting. Background Technology

[0002] Laser cutting utilizes the high power density of a laser beam, focusing it onto a very small spot to rapidly heat the material until it reaches its boiling point, vaporizing it and creating a space. The laser beam is then moved to cut the material's surface, completing the cutting process. Besides a high-energy laser, assist gas is indispensable for laser cutting. The main assist gases are oxygen, nitrogen, and compressed air. Compressed air is easier to obtain and cheaper than oxygen and nitrogen. Because laser cutting sometimes requires outdoor operations, the mobility of the air compressor used in laser cutting equipment is particularly important.

[0003] Furthermore, during laser cutting, compressed air needs to maintain a stable pressure to assist in cutting, cooling, and removing molten slag. To ensure stable operation of the laser cutting equipment, an air compressor needs to provide a stable supply of compressed air. If gas backflow causes a sudden drop in pressure, it may affect cutting accuracy or cause processing interruption, and may also lead to damage to the air filter and waste of lubricating oil.

[0004] The technical problem to be solved by this utility model is: how to solve the problem that the existing air compressor has poor mobility and stability and cannot be adapted to laser cutting equipment. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a special air compressor for laser cutting, which has the characteristics of compact structure, good mobility, stable pressure output and prevention of backflow of compressed air and lubricating oil.

[0006] The technical solution adopted by this utility model is as follows: a special air compressor for laser cutting, including an air tank, a compressor main unit, an oil-gas separator, and a cooler. A first mounting platform is provided on the top of the air tank. The compressor main unit and the oil-gas separator are mounted on the first mounting platform. The cooler is located above the compressor main unit and the oil-gas separator. An air inlet valve is installed at the air inlet of the compressor main unit, and an air filter is installed at the air inlet of the air inlet valve. The exhaust outlet of the compressor main unit is connected to the air inlet of the oil-gas separator through an exhaust pipe. The exhaust outlet of the oil-gas separator is connected to the air inlet of the cooler. The oil outlet of the oil-gas separator is connected to the compressor main unit. The air outlet of the cooler is connected to the air inlet of the air tank. A check valve is provided on the exhaust pipe.

[0007] The laser-cutting-specific air compressor of this application features a more compact and mobile structure by mounting the compressor unit, oil-gas separator, and cooler on an air tank, facilitating easy relocation of the air compressor alongside the laser cutting equipment. The air tank stores compressed air, acting as a buffer and ensuring more stable output compressed air pressure to meet the stable compressed air requirements of the laser cutting equipment. Furthermore, a check valve on the exhaust pipe prevents backflow of lubricating oil and compressed air when the air compressor stops or is unloaded, protecting the air filter and reducing lubricating oil consumption, thus ensuring the normal operation of both the air compressor and the laser cutting equipment.

[0008] In some embodiments, the check valve is provided with a first flange and a second flange at its two ends, respectively. The first flange is detachably connected to the exhaust outlet of the compressor host, and the second flange is detachably connected to the exhaust pipe.

[0009] By adopting the above technical solution, the check valve is fixed to the compressor host through the first flange, and the exhaust pipe is connected to the check valve through the second flange, which can make the check valve installation more secure and improve the check valve's impact resistance.

[0010] In some embodiments, the system also includes a chassis mounted on the first mounting platform, with the compressor and oil-gas separator housed within the chassis, a cooler mounted on the top of the chassis, and an air inlet on the side of the chassis.

[0011] In some implementations, a control cabinet is also included, which is embedded in one side of the chassis, and a controller is provided on the surface of the control cabinet.

[0012] In some embodiments, the cooler includes an oil-cooled component, an air-cooled component, and a blower box. The oil-cooled component and the air-cooled component are arranged side by side, and the blower box is located at the bottom or top of the oil-cooled component and the air-cooled component. A fan is installed on the blower box, and a hot air outlet corresponding to the cooler is provided on the top of the casing.

[0013] By adopting the above technical solution, air can be drawn in from the side of the chassis, and hot air can be exhausted from the top of the chassis. This reduces the possibility of hot air being sucked back into the chassis, and the hot air will not blow directly on the operator, making it safer and more comfortable.

[0014] In some embodiments, the oil outlet of the oil-gas separator is equipped with a temperature controller. The first outlet of the temperature controller is connected to the oil inlet of the oil cooler, the oil outlet of the oil cooler is connected to the oil return port of the compressor, and the second outlet of the temperature controller is connected to the oil return port of the compressor.

[0015] In some implementations, an oil filter is installed on the thermostat.

[0016] In some embodiments, a post-processing unit is also included, which includes a refrigerated dryer. A second mounting platform is also provided on the gas storage tank. The second mounting platform is located on one side of the first mounting platform. The refrigerated dryer is mounted on the second mounting platform. The air inlet of the refrigerated dryer is connected to the air outlet of the gas storage tank. The air outlet of the refrigerated dryer is connected to an external gas-using device.

[0017] By adopting the above technical solution, the refrigerated dryer can further process the air discharged from the air tank, reduce the water content in the compressed air, and make the compressed air supplied to the laser cutting equipment purer.

[0018] In some embodiments, the post-processing unit further includes a first filter disposed between the air inlet of the refrigerated dryer and the air outlet of the air storage tank.

[0019] By adopting the above technical solution and setting a first filter, impurities entering the refrigerated dryer from the air tank can be removed, thereby protecting the refrigerated dryer and extending its service life.

[0020] In some embodiments, the post-treatment mechanism further includes a second filter disposed at the air outlet of the refrigerated dryer.

[0021] By adopting the above technical solution, the compressed air output from the refrigerated dryer can be filtered by setting a second filter to ensure the purity of the compressed air supplied to the laser cutting equipment, so that the laser cutting equipment can work stably.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 5A preferred embodiment of the present invention provides a laser cutting-specific air compressor 100, comprising an air tank 10, a compressor 20, an oil-gas separator 90, and a cooler 30. A first mounting platform 11 is provided on the top of the air tank 10. The compressor 20 and the oil-gas separator 90 are mounted on the first mounting platform 11. The cooler 30 is positioned above the compressor 20 and the oil-gas separator 90. An intake valve 21 is installed at the air inlet of the compressor 20, and an air filter 22 is installed at the air inlet of the intake valve 21. The exhaust outlet of the compressor 20 is connected to the air inlet of the oil-gas separator 90 via an exhaust pipe 40. The exhaust outlet of the oil-gas separator 90 is connected to the air inlet of the cooler 30. The oil outlet of the oil-gas separator 90 is connected to the compressor 20. The air outlet of the cooler 30 is connected to the air inlet of the air tank 10. A check valve 41 is provided on the exhaust pipe 40.

[0032] The laser-cutting-specific air compressor 100 of this application, by mounting the compressor host 20, oil-gas separator 90, and cooler 30 on the air tank 10, makes the overall structure of the air compressor more compact and highly mobile, facilitating the transfer of the air compressor with the laser cutting equipment. The air tank 10 stores compressed air, acting as a buffer and ensuring more stable output compressed air pressure to meet the stable compressed air requirements of the laser cutting equipment. Furthermore, by installing a check valve 41 on the exhaust pipe 40, backflow of lubricating oil and compressed air is prevented when the air compressor stops or is unloaded, protecting the air filter 22 and reducing lubricating oil consumption, thus ensuring the normal operation of both the air compressor and the laser cutting equipment.

[0033] like Figure 5 As shown, the check valve 41 has a first flange 42 and a second flange 43 at its two ends. The first flange 42 is detachably connected to the exhaust outlet of the compressor 20, and the second flange 43 is detachably connected to the exhaust pipe 40. The check valve 41 is fixed to the compressor 20 by the first flange 42, and the exhaust pipe 40 is connected to the check valve 41 by the second flange 43, which makes the installation of the check valve 41 more secure and improves the impact resistance of the check valve 41.

[0034] Furthermore, the first flange 42 and the second flange 43 are connected by bolts, which can further improve the reliability of the check valve 41 after installation and enhance its anti-detachment performance.

[0035] To reduce vibration during operation of the compressor host 20, a shock absorber is installed at the bottom of the compressor host 20, and a connecting screw passes through the shock absorber to fix the compressor host 20 onto the first mounting platform 11.

[0036] like Figure 1 and Figure 2As shown, the laser cutting-specific air compressor 100 of this application also includes a casing 50 mounted on the first mounting platform 11. The compressor unit 20 and the oil-gas separator 90 are built into the casing 50. The cooler 30 is mounted on the top of the casing 50, and an air inlet 51 is provided on the side of the casing 50. The casing 50 can prevent the compressor unit 20 and the oil-gas separator 90, which have high operating temperatures, from being exposed, thus improving safety and making the air compressor more aesthetically pleasing.

[0037] like Figure 1 As shown, the laser cutting-specific air compressor 100 of this application also includes a control cabinet 60, which is embedded in one side of the chassis 50. A controller 61 is mounted on the surface of the control cabinet 60. The control cabinet 60 is used to install various control components, such as frequency converters and other electrical control components. Operators can control the operation of the air compressor through the controller 61 and can observe various parameters of the air compressor through the display of the controller 61, so that users can understand the operating status of the air compressor.

[0038] like Figure 3 and Figure 4 As shown, the cooler 30 includes an oil-cooled component 31, an air-cooled component 32, and a blower box 33. The oil-cooled component 31 and the air-cooled component 32 are arranged side by side. The blower box 33 is located at the bottom or top of the oil-cooled component 31 and the air-cooled component 32. A fan 34 is installed on the blower box 33. The top of the casing 50 is provided with a hot air outlet 52 corresponding to the cooler 30. Air can be drawn in from the side of the casing 50, and then the hot air is discharged from the top of the casing 50. This reduces the possibility of hot air being drawn back into the casing 50, and the hot air will not blow directly on the operator, making it safer and more comfortable.

[0039] Furthermore, the oil outlet of the oil-gas separator 90 is equipped with a temperature controller 70. The first outlet of the temperature controller 70 is connected to the oil inlet of the oil cooler 31, the oil outlet of the oil cooler 31 is connected to the oil return port of the compressor 20, and the second outlet of the temperature controller 70 is connected to the oil return port of the compressor 20.

[0040] Preferably, in this application, the temperature controller 70 integrates an oil filter 71. In other embodiments, the temperature controller 70 and the oil filter 71 may also be separate components.

[0041] To further improve the purity of compressed air and ensure its quality matches the requirements of laser cutting equipment, the laser cutting-specific air compressor 100 of this application also includes a post-processing mechanism 80. The post-processing mechanism 80 includes a refrigerated dryer 81. A second mounting platform 12 is also provided on the air tank 10, located to one side of the first mounting platform 11. The refrigerated dryer 81 is mounted on the second mounting platform 12, with its inlet connected to the outlet of the air tank 10 and its outlet connected to external air-consuming equipment. The refrigerated dryer 81 can further process the air discharged from the air tank 10, reducing the water content in the compressed air and making the compressed air supplied to the laser cutting equipment purer.

[0042] Preferably, the first mounting platform 11 and the second mounting platform 12 are fixed to the surface of the gas storage tank 10 by welding.

[0043] Furthermore, the post-processing unit 80 also includes a first filter 82, which is disposed between the air inlet of the refrigerated dryer 81 and the air outlet of the air tank 10. By providing the first filter 82, impurities entering the refrigerated dryer 81 from the air tank 10 can be removed, thereby protecting the refrigerated dryer 81 and extending its service life.

[0044] Furthermore, the post-processing unit 80 also includes a second filter 83, which is located at the air outlet of the refrigerated dryer 81. By providing the second filter 83, the compressed air output from the refrigerated dryer 81 can be filtered to ensure the purity of the compressed air supplied to the laser cutting equipment, thereby enabling the laser cutting equipment to operate stably.

[0045] Preferably, multiple second filters 83 can be provided, and the multiple second filters 83 are arranged in series.

[0046] In this example, the refrigerated dryer 81 is located outside the casing 50, and the first filter 82 and the second filter 83 are located on the pipe outside the casing 50. This arrangement makes it easy to replace consumable parts such as the first filter 82 and the second filter 83.

[0047] To enhance safety, safety valves are installed on both the oil-gas separator 90 and the gas storage tank 10.

[0048] When the compressor 20 is stopped or unloaded, the high-pressure gas and lubricating oil in the oil-gas separator 90 will flow back into the compressor 20 and be ejected from the air filter 22 through the intake valve 21, causing damage to the air filter 22 and wasting lubricating oil. Therefore, in order to prevent the high-pressure gas and lubricating oil from flowing back and damaging the air compressor, thereby affecting the normal operation of the laser cutting equipment, the laser cutting-specific air compressor 100 of this application is equipped with a check valve 41 on the exhaust pipe 40 between the compressor 20 and the oil-gas separator 90. When the compressor 20 is stopped or unloaded, the high-pressure gas in the oil-gas separator 90 will push against the spring in the check valve 41, blocking the backflow of lubricating oil and gas in the exhaust pipe 40, preventing it from being ejected from the air filter 22, thus protecting the air filter 22 and preventing the lubricating oil from spraying out and causing a safety accident, ensuring that the air compressor can work smoothly and safely, and providing stable compressed air for the laser cutting equipment.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
