Detailed Implementation

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0018] Please refer to Figure 1 An embodiment of this utility model provides a nitrogen generator, comprising: The housing 100 includes a top plate 110, a bottom plate 120, a first side plate 130, a second side plate 140, a horizontal partition plate 150, and a vertical partition plate 160. The top plate 110, the first side plate 130, the bottom plate 120, and the second side plate 140 are connected end to end in sequence. The horizontal partition plate 150 is located between the top plate 110 and the bottom plate 120 and is connected to the first side plate 130. The vertical partition plate 160 is located between the first side plate 130 and the second side plate 140 and is connected to the top plate 110 and the horizontal partition plate 150 respectively. Air compressor 201 is disposed in the space enclosed by top plate 110, first side plate 130, horizontal partition plate 150 and vertical partition plate 160; A shock-absorbing component 300 is disposed between the air compressor 201 and the cross plate 150; Fans 202 are respectively provided on the first side plate 130 and the partition plate 160.

[0019] The air compressor 201 is housed within the space enclosed by the top plate 110, the first side plate 130, the horizontal partition plate 150, and the vertical partition plate 160, separating it from other components such as the air tank 203 to prevent collisions and friction between the air compressor 201 and other parts. Simultaneously, fans 202 are respectively installed on the first side plate 130 and the vertical partition plate 160 to effectively dissipate heat from the air compressor 201. This heat prevents it from affecting the operation of other components, thereby improving the stability and durability of the nitrogen generator.

[0020] like Figure 1 and Figure 2 As shown, the housing 100 includes a top plate 110, a bottom plate 120, a first side plate 130, a second side plate 140, a horizontal partition plate 150, and a vertical partition plate 160. The top plate 110, bottom plate 120, etc., are made of sheet metal, and adjacent sheet metal parts can be fixed together by welding or other methods. In addition to welding, the top plate 110, first side plate 130, horizontal partition plate 150, and vertical partition plate 160 are also reinforced by L-shaped reinforcing ribs. For example, one end of the L-shaped reinforcing rib is fixed to the horizontal partition plate 150 by bolts, and the other end of the L-shaped reinforcing rib is fixed to the first side plate 130 by bolts to ensure the stability of the connection between the horizontal partition plate 150 and the first side plate 130.

[0021] When the air compressor 201 is supported on the horizontal partition plate 150, there are gaps between the air compressor 201 and the first side plate 130, the top plate 110 and the vertical partition plate 160, which not only helps with heat dissipation, but also reduces the vibration impact of the air compressor 201 on other components.

[0022] like Figure 1 and Figure 2 As shown, a vibration damping assembly 300 is provided between the air compressor 201 and the partition plate 150 to reduce the noise and vibration during the operation of the air compressor 201. The vibration damping assembly 300 includes: Upper rubber component 310 is disposed between the air compressor 201 and the partition plate 150.

[0023] The upper rubber component 310 is connected to the partition plate 150 by bolts passing through the mounting holes on the air compressor 201 and through the upper rubber component 310, so that the upper rubber component 310 is held between the air compressor 201 and the partition plate 150, preventing the air compressor 201 from colliding with the partition plate 150 and generating noise during operation.

[0024] The upper rubber part 310 has a relatively high hardness, which not only reduces noise but also provides a buffer for the vibration of the air compressor 201 during operation, reducing vibration transmission.

[0025] The number of the upper rubber parts 310 is four, and they are distributed at the four corners of the air compressor 201 to evenly distribute the vibration load and enhance the stability of the whole machine.

[0026] refer to Figure 2 The shock absorption assembly 300 further includes: Lower rubber component 330, the lower rubber component 330 is disposed on the partition plate 150; A support plate 320 is disposed between the upper rubber component 310 and the lower rubber component 330.

[0027] By incorporating the lower rubber component 330, noise reduction and vibration damping capabilities are further enhanced. The lower rubber component 330 is also secured with bolts, which pass through the support plate 320 and the lower rubber component 330, ultimately connecting to the transverse partition plate 150. The support plate 320 is square, and there are four lower rubber components 330, positioned at the four corners of the support plate 320.

[0028] The support plate 320 is made of sheet metal and is combined with the upper rubber part 310 and the lower rubber part 330 to effectively improve the noise reduction and vibration damping capabilities.

[0029] The upper rubber component 310 and the lower rubber component 330 are staggered to optimize stress distribution, avoid stress concentration, effectively improve stress conditions, and increase fatigue life.

[0030] like Figure 2 As shown, fans 202 are respectively provided on the first side plate 130 and the partition plate 160.

[0031] The fan 202 on the vertical partition 160 is used to introduce gas, and the fan 202 on the first side plate 130 is used to exhaust gas, so that the gas passes through the air compressor 201 and dissipates the heat generated by the air compressor 201, thereby achieving a heat dissipation effect on the air compressor 201. The fan 202 on the first side plate 130 is located between the top plate 110 and the horizontal partition 150, and is opposite to the air compressor 201.

[0032] like Figure 1 and Figure 2 As shown, the nitrogen generator further includes: Air tank 203 is disposed between the partition plate 150 and the bottom plate 120.

[0033] The air tank 203 is fixed on the base plate 120 and there is a gap between it and the partition plate 150, which further prevents the air tank 203 from coming into contact with the air compressor 201.

[0034] The nitrogen generator also includes an inlet filter 216, which is connected to the air compressor 201. The inlet of the inlet filter 216 is arranged downward, i.e. towards the base plate 120, for filtering the gas and introducing it into the air compressor 201.

[0035] refer to Figure 4 The base plate 120 has multiple holes 121, which are used not only for heat dissipation, but also for introducing gas through the holes 121, which is then introduced into the air tank 203 for storage through the air inlet filter 216, and the gas flows through the air compressor 201 under the action of the fan 202. The holes 121 may be oblong in shape.

[0036] like Figures 1 to 3 As shown, a nitrogen membrane 208 is also provided on the base plate 120. The nitrogen membrane 208 is located on one side of the air tank 203 and has a gap with the partition plate 150. The nitrogen membrane 208 is filled with hollow fiber membrane bundles. After clean compressed air enters, oxygen, water vapor, etc. preferentially permeate through the membrane wall and are discharged, while nitrogen is enriched, thereby obtaining high-purity nitrogen.

[0037] like Figure 1 and Figure 3 As shown, a connecting assembly 400 is provided on the inner wall of the second side plate 140, and the connecting assembly 400 has multiple mounting holes 410. The connecting assembly 400 is used to install parts, and bolts pass through the parts and connect with the mounting holes 410 to achieve fixation. There is a gap between the parts and the partition plate 160 to avoid direct contact with the air compressor 201. A condenser 215 is provided between the partition plate 160 and the parts, and the condenser 215 can be fixed to the top plate 110.

[0038] The components include a pressure relief solenoid valve 204, a water outlet filter 205, a silencer 206, a drain solenoid valve 207, a mist filter 209, a hydrocarbon removal filter 210, a pressure reducing valve 211, a timer 212, a pressure gauge 213, and a yellow-green indicator 214.

[0039] The inlet filter 216, air compressor 201, condenser 215, air tank 203, hydrocarbon removal filter 210, mist filter 209, water outlet filter 205, and nitrogen membrane 208 are connected in sequence. Air is filtered by the inlet filter 216 and then drawn into the air compressor 201, which compresses the air to produce high-temperature, high-pressure compressed air. The condenser 215 cools the compressed air, and the resulting condensate is discharged under the control of the drain solenoid valve 207. The cooled compressed air is stored in the air tank 203. The hydrocarbon removal filter 210 then removes gaseous pollutants such as oil vapor and hydrocarbons from the compressed air. The mist filter 209 removes residual liquid water mist and oil mist particles from the compressed air, and the water outlet filter 205 filters out fine solid particles and dust. Finally, nitrogen and exhaust gas are obtained by passing through the nitrogen membrane 208.

[0040] Exhaust gas is discharged through the silencer 206, reducing exhaust noise. Nitrogen output pressure is regulated by the pressure reducing valve 211 and displayed by the pressure gauge 213. The equipment operating time is recorded by the timer 212, and nitrogen purity is monitored by the yellow-green indicator 214. The pressure relief solenoid valve 204 is used to quickly depressurize and flush the nitrogen membrane during startup, shutdown, or standby, removing impurities from the membrane surface.

[0041] like Figure 1 As shown, the bottom of the base plate 120 of the housing 100 is provided with wheels 170.

[0042] In summary, the air compressor 201 is disposed within the space enclosed by the top plate 110, the first side plate 130, the horizontal partition plate 150, and the vertical partition plate 160, so that the air compressor 201 is physically isolated from other components such as the air tank 203, preventing the air compressor 201 from colliding and rubbing against other components. Furthermore, by providing fans 202 on the first side plate 130 and the vertical partition plate 160 respectively, the heat dissipation capacity is improved, effectively ensuring the reliability and durability of the nitrogen generator.

[0043] The embodiments described above are only used to illustrate the technical ideas and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. The scope of patent application of this utility model should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in this utility model still fall within the patent scope of this utility model.
