Abstract
Description
Technical Field
[0001] This utility model relates to the field of VPSA oxygen generation technology, and in particular to a low-noise, low-energy-consumption VPSA oxygen generation device. Background Technology
[0002] VPSA oxygen production utilizes specialized VPSA molecular sieves to selectively adsorb impurities such as nitrogen, carbon dioxide, and water from the air. Under vacuum conditions, the molecular sieves are desorbed, thus producing high-purity oxygen in a cyclical manner. Typically, a blower draws in air as raw material, which undergoes adsorption, filtration, and separation to form the desired gas.
[0003] VPSA oxygen generators typically include air compressors, dryers, pressure stabilizers, adsorption units, and storage units. The air compressors and dryers are usually directly mounted on a mounting plate, generating significant noise during operation. This noise can negatively impact the health of production personnel. Furthermore, the noise is often accompanied by vibration. For the dryer's fan, abnormal vibration increases friction between the impeller and the air, reducing fan efficiency. Lower efficiency requires more electrical energy to deliver the same volume of air, thus increasing energy consumption. To address these issues, we have proposed this low-noise, low-energy VPSA oxygen generator. Utility Model Content

[0023] This utility model provides a technical solution:
[0024] Please see Figures 1-5 A low-noise, low-energy-consumption VPSA oxygen generator includes: a mounting base plate 1, a pressure stabilizing tank 2, an adsorption tower 3, a gas storage tank 4, a mounting shell 5, an air compressor 11, and a compressed air dryer 12. The pressure stabilizing tank 2, adsorption tower 3, gas storage tank 4, air compressor 11, and compressed air dryer 12 are all existing technologies. The adsorption process, pressure equalization and depressurization process, vacuuming process, pressure equalization and pressurization process, and product gas backflushing and rinsing process are not described in detail. The air compressor 11 is connected to an air inlet pipe 15. The mounting shell 5 is equipped with a noise reduction mechanism for reducing noise. The noise reduction mechanism includes a first sound-absorbing cotton 6 installed inside the mounting shell 5. Both sides of the mounting shell 5 are provided with side plates 10. The side walls of the side plates 10 are provided with second sound-absorbing cotton 7. The side walls of the side plates 10 are provided with multiple air vents 8.
[0025] The side wall of the air intake pipe 15 is provided with an air filtration mechanism. The filtration mechanism includes an air intake shroud 9 fixedly connected to the side wall of the air intake pipe 15. Multiple mounting rings 16 are fixedly connected to the inner wall of the air intake shroud 9. A first filter screen 13 is provided in the mounting ring 16, which can filter the air entering the air compressor 11 to prevent impurities from affecting the oxygen production.
[0026] Furthermore, the mounting ring 16 is threadedly connected to the first filter screen 13, and the first rotating block 14 is fixedly connected to the side wall of the first filter screen 13 to facilitate the disassembly of the first filter screen 13.
[0027] Furthermore, a second filter screen 18 is provided inside the vent pipe 8, which can reduce dust adhesion to the air compressor 11, the compressed air dryer 12, the first sound-absorbing cotton 6, and the second sound-absorbing cotton 7. The second filter screen 18 is threadedly connected to the vent pipe 8, making it easy to disassemble the second filter screen 18.
[0028] Furthermore, each of the multiple ventilation pipes 8 is equipped with a fan 19, which can accelerate the airflow inside the housing 5 by activating the fan 19, thereby further ensuring the heat dissipation effect of the equipment.

[0030] In practical use, the working principle of this utility model is as follows:
[0031] It should be noted that this utility model is a low-noise, low-energy-consumption VPSA oxygen generator. The screw air compressor 11 compresses air to provide raw materials for oxygen production, with a maximum pressure of 1.0 MPa. The compressed air dryer 12 removes moisture, carbon dioxide, and other impurities from the compressed air. The pressure stabilizing tank 2 balances pressure fluctuations before supplying air to the oxygen generator. The adsorption tower 3 uses VPSA molecular sieve pressure swing adsorption technology to separate oxygen from the air. The oxygen enters the storage tank 4 for storage. The air compressor 11 and the compressed air dryer 12 are placed inside the housing. The first sound-absorbing cotton 6 and the second sound-absorbing cotton 7 can absorb and reflect the sound waves generated by the operation of the equipment, reducing the outward transmission of noise and significantly reducing the noise generated by the operation of the equipment. At the same time, the housing itself can also play a certain role in sound insulation, reducing sound transmission. It can also reduce abnormal vibration by reducing noise, reduce the friction between the impeller of the fan and the air, improve the efficiency of the fan, and thus reduce energy consumption.
[0032] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
