Description

Technical Field

[0001] This utility model relates to the field of gas separation technology, and in particular to an integrated nitrogen generator. Background Technology

[0002] Nitrogen (N2), as an inert gas, has wide applications in industry, medicine, food preservation, and electronics manufacturing. For example, in industrial production, nitrogen is used for metal heat treatment, chemical reaction protection, and pipeline purging; in food preservation, nitrogen is used to extend shelf life; in the medical field, nitrogen is used for anesthesia and cryotherapy; and in electronics manufacturing, nitrogen is used to prevent oxidation and contamination. With the increasing demand for nitrogen across various industries, the technological development of nitrogen generating equipment is receiving increasing attention.

[0003] However, existing nitrogen generating equipment still suffers from excessive noise, with the air compressor being the most noisy component. The noise generated during operation can negatively impact the working environment. Reducing noise requires a thicker noise-reducing layer, but air compressors generate significant heat during prolonged operation. A thicker noise-reducing layer would hinder the compressor's heat dissipation, reducing its lifespan. Furthermore, using a thicker noise-reducing layer would result in a bulky device. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model provides an integrated, low-noise, and highly efficient nitrogen generator. Through modular design and multiple sound insulation and heat dissipation structures, it solves the defects of traditional nitrogen generators. The specific solution is as follows:

[0005] A nitrogen generator includes an integrated base, on which at least two air compressors are fixedly installed. Each air compressor has an air outlet, and the air outlets of the at least two air compressors are connected in parallel.

[0006] At least two noise shielding boxes are fixedly installed on the integrated base, and each noise shielding box is set to cover the air compressor.

[0007] The air compressor is provided with an air inlet, and both the air inlet and the air outlet are covered with sound insulation tubes.

[0008] The noise shielding box is equipped with a heat dissipation mechanism, and an external soundproof cover is fixedly installed on the integrated base, covering at least two sets of noise shielding boxes.

[0009] Furthermore: the heat dissipation mechanism includes an air duct and a heat dissipation fan. The air duct is fixedly installed inside the noise shielding box, and the heat dissipation fan is fixedly installed inside the air duct. The heat dissipation fan forms a heat dissipation airflow inside the noise shielding box through the air duct, and the heat dissipation airflow is used to remove the heat from the air compressor.

[0010] Furthermore, a soundproof gap is left between the inner wall of the outer soundproof enclosure and the noise shielding box.

[0011] Furthermore, the sound insulation gap is a closed structure, and the sound insulation gap is vacuum-sealed.

[0012] Furthermore: a pretreatment module is fixedly installed on the integrated base, and the air outlet of the air compressor is configured to lead to the pretreatment module.

[0013] Furthermore: the pretreatment module includes a multi-stage filter and a dryer, and the gas in the outlet is directed to the multi-stage filter and dryer.

[0014] Furthermore, an integrated adsorption unit is fixedly installed on the integrated base, and the pretreatment module is connected to the integrated adsorption unit.

[0015] Furthermore: the integrated adsorption unit consists of multiple vertically stacked adsorption towers, with the gas paths of the multiple adsorption towers connected in series.

[0016] Furthermore: the air compressor is provided in two sets, and a three-way pipe and a switching valve are connected between the air outlets of the two sets of air compressors.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Initial noise reduction is achieved by covering the air compressor with a noise shielding box. Since it has an air inlet and an air outlet, the noise shielding box will not affect the normal operation of the air compressor.

[0019] 2. At least two sets of air compressors can operate simultaneously or alternately to ensure stable operation of the equipment;

[0020] 3. Install sound insulation tubes at the air inlet and outlet to achieve secondary noise reduction;

[0021] 4. By covering at least two sets of noise shielding boxes with an external soundproof cover, three levels of noise reduction can be achieved, which can effectively reduce the transmission of noise;

[0022] 5. Use a cooling system to dissipate heat from the air compressor to ensure its stable operation.

[0023] This utility model of an integrated nitrogen generator solves the problems of high noise, poor heat dissipation, and large footprint of traditional nitrogen generators through integrated design, multiple sound insulation structures, and a high-efficiency heat dissipation mechanism. It is suitable for multiple fields such as industry, medical care, and food preservation.

Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0034] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] like Figure 1-5 As shown, a nitrogen generator includes an integrated base 1, on which at least two air compressors 2 are fixedly installed. Each air compressor 2 has an air outlet 3, and the air outlets 3 of the at least two air compressors 2 are connected in parallel.

[0038] At least two sets of noise shielding boxes 4 are fixedly installed on the integrated base 1, and the noise shielding boxes 4 are set to cover the air compressor 2 one by one.

[0039] The air compressor 2 is provided with an air inlet 5, and the outer sides of the air inlet 5 and the air outlet 3 are covered with sound insulation cylinders 6.

[0040] The noise shielding box 4 is equipped with a heat dissipation mechanism 7, and an outer sound insulation cover 8 is fixedly installed on the integrated base 1. The outer sound insulation cover 8 covers at least two sets of noise shielding boxes 4.

[0041] The principle is as follows: First, the noise shielding box 4 is used to cover the air compressor 2 to achieve initial noise reduction. Since there is an air inlet 5 and an air outlet 3, the noise shielding box 4 will not affect the normal operation of the air compressor 2. In addition, at least two sets of air compressors 2 can operate simultaneously or alternately to ensure the stable operation of the equipment. Furthermore, sound insulation cylinders 6 are installed at the air inlet 5 and the air outlet 3 to achieve secondary noise reduction. Finally, at least two sets of noise shielding boxes 4 are covered by an outer sound insulation cover 8 to achieve tertiary noise reduction, which can effectively reduce the transmission of noise. In addition, a heat dissipation mechanism 7 is used to dissipate heat from the air compressor 2 to ensure the stable operation of the air compressor 2.

[0042] Furthermore, the heat dissipation mechanism 7 includes an air duct 71 and a cooling fan 72. The air duct 71 is fixedly installed inside the noise shielding box 4, and the cooling fan 72 is fixedly installed inside the air duct 71. The cooling fan 72 forms a cooling airflow inside the noise shielding box 4 through the air duct 71. The cooling airflow is used to remove the heat from the air compressor 2. After the cooling fan 72 is turned on, the airflow can flow continuously inside the noise shielding box 4 to avoid heat accumulation and thus prevent damage to the air compressor 2.

[0043] Furthermore, a soundproof gap 9 is left between the inner wall of the outer soundproof cover 8 and the noise shielding box 4, which can achieve a better soundproofing effect.

[0044] Furthermore, the sound insulation gap 9 is a closed structure, and the sound insulation gap 9 is set to be vacuumed; by utilizing a simulated empty environment, further noise reduction can be achieved, which can better reduce the transmission of sound.

[0045] Furthermore: a pretreatment module 10 is fixedly installed on the integrated base 1, and the air outlet 3 of the air compressor 2 is connected to the pretreatment module 10; the pretreatment module 10 includes a multi-stage filter 101 and a dryer 102, and the gas in the air outlet 3 is connected to the multi-stage filter 101 and the dryer 102; the pretreatment module 10 can filter and dry nitrogen, thereby ensuring the purity of nitrogen.

[0046] Furthermore: An integrated adsorption unit 11 is fixedly installed on the integrated base 1, and the pretreatment module 10 is connected to the integrated adsorption unit 11; the integrated adsorption unit 11 is composed of multiple vertically stacked adsorption towers 111, and the multiple adsorption towers 111 are connected in series with each other through gas paths; multiple adsorption towers 111 can be used to absorb impurities in nitrogen, thereby ensuring the production purity of nitrogen.

[0047] Furthermore: the air compressor 2 is provided in two sets, and a three-way pipe 12 and a switching valve 13 are connected between the air outlets 3 of the two sets of air compressor 2; when the two sets of air compressor 2 operate alternately, the airflow can be switched by using the switching valve 13 to ensure the stable operation of the equipment. At the same time, the alternating operation of the two sets of air compressor 2 can ensure the stable operation of the equipment for a long time, and the air compressor 2 is not prone to overheating and damage.

[0048] For ease of understanding, the present invention also provides the following implementation examples:

[0049] Example 1: As Figure 1-3 As shown, a nitrogen generator includes an integrated base 1, on which two sets of air compressors 2 are fixedly installed. Each air compressor 2 has an air outlet 3, and the air outlets 3 of the two sets of air compressors 2 are connected in parallel to improve gas output efficiency. Two sets of noise shielding boxes 4 are also fixedly installed on the integrated base 1, each covering one of the air compressors 2 to effectively reduce noise. The air inlet 5 and the air outlet 3 of the air compressors 2 are covered with sound insulation cylinders 6 to further reduce noise transmission. A heat dissipation mechanism 7 is provided inside the noise shielding box 4. An outer sound insulation cover 8 is fixedly installed on the integrated base 1, covering at least two sets of noise shielding boxes 4 to form a double sound insulation structure.

[0050] Example 2: As Figure 3-5 As shown, the heat dissipation mechanism 7 includes an air duct 71 and a cooling fan 72; the air duct 71 is fixedly installed inside the noise shielding box 4, and the cooling fan 72 is fixedly installed inside the air duct 71; the cooling fan 72 forms a cooling airflow inside the noise shielding box 4 through the air duct 71, and the airflow direction is as follows. Figure 5 As indicated by the middle arrow, it is used to remove the heat generated by the air compressor 2, ensuring that the equipment operates stably for a long time.

[0051] Example 3: As Figure 4 As shown, a sound insulation gap 9 is left between the inner wall of the outer sound insulation cover 8 and the noise shielding box 4; the sound insulation gap 9 is a closed structure and is vacuumed inside; this design utilizes the principle of vacuum sound insulation to further reduce noise transmission and make the equipment operate more quietly.

[0052] Example 4: Figure 1-4 As shown, a pretreatment module 10 is fixedly installed on the integrated base 1, and the air outlet 3 of the air compressor 2 leads to the pretreatment module 10. The pretreatment module 10 includes a multi-stage filter 101 and a dryer 102. The gas in the outlet 3 first passes through the multi-stage filter 101 to remove impurities, and then passes through the dryer 102 to remove moisture, ensuring that the gas entering the subsequent modules is pure and dry.

[0053] Example 5: Figure 5As shown, an integrated adsorption unit 11 is fixedly installed on the integrated base 1, and the pretreatment module 10 is connected to the integrated adsorption unit 11. The integrated adsorption unit 11 is composed of multiple vertically stacked adsorption towers 111, and the multiple adsorption towers 111 are connected in series with each other through gas paths. This design improves the nitrogen separation efficiency and saves the equipment floor space.

[0054] Example 6: As Figure 1-4 As shown, there are two sets of air compressors 2. A three-way pipe 12 and a switching valve 13 are connected between the air outlets 3 of the two sets of air compressors 2. This design allows for switching the use of air compressors 2. When one set of air compressors 2 is in use, its air compression is reduced by half, while the other set of air compressors 2 is in a paused state and the heat is quickly removed by the heat dissipation mechanism 7. After working for a period of time, the air compressor 2 can be switched to the other set of air compressors 2 for operation, which can ensure the stable operation of the equipment for a long time and prevent the air compressors 2 from overheating and being damaged.

[0055] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
