[0002] In modern industrial production, nitrogen generators are widely used in various fields such as chemical, food, and electronics, playing a vital role in providing high-purity nitrogen. However, the oxygen-enriched waste gas generated during nitrogen generation often contains moisture and other impurities. If left untreated, direct discharge will cause serious environmental pollution and may affect the normal operation of equipment. Therefore, it is necessary to collect and treat the oxygen-enriched waste gas from nitrogen generators.

[0003] Traditional waste gas treatment methods are mostly based on single physical or chemical treatments, which often fail to meet the requirements of high efficiency and environmental protection. Many existing technologies suffer from low efficiency, high energy consumption, and frequent equipment maintenance when removing moisture and impurities from waste gases. Furthermore, the lifespan and cleaning effectiveness of filters are also important factors affecting waste gas treatment efficiency. Traditional filters are prone to clogging after prolonged use, leading to decreased treatment efficiency, increased maintenance costs, and downtime. Therefore, a nitrogen generator oxygen-enriched waste gas collection and utilization device is proposed. Utility Model Content

[0007] In the above technical solution, the cleaning roller and the filter screen are bonded together, and the gear and the rack plate are meshed together.

[0008] In the above technical solution, the end of the delivery pipe away from the air pump passes through the heat dissipation fins and is fixedly connected inside the separation box.

[0009] In the above technical solution, both the connecting block and the outer side of the rotating shaft are slidably connected to the upper wall of the separation box.

[0010] In the above technical solution, the bottom of the base plate is further provided with casters at all four corners, and the bottom of the separation box is provided with two collection boxes.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5 The device shown is a nitrogen generator oxygen-enriched waste gas collection and utilization device, including a base plate 1. The base plate 1 serves as the basic structure of the entire device, providing stable support and ensuring the firm installation of each component and the overall stability of the equipment. An air pump 2 is installed on the upper front of the base plate 1. The air pump 2 is used to extract oxygen-enriched waste gas from the nitrogen generator. A heating shell 3 is installed at the input end of the air pump 2, and an electric heating wire 4 is installed inside the heating shell 3. The heating shell 3 and the electric heating wire 4 are used to heat the waste gas, helping to remove moisture from the waste gas and preventing condensation during subsequent treatment. A conveying pipe 7 is installed at the output end of the air pump 2, used to convey the heated waste gas. A cooling box 5 is fixedly connected to the upper middle of the base plate 1. The cooling box 5 is used to cool the heated waste gas for subsequent separation and treatment. Heat dissipation fins 6 are fixedly connected inside the cooling box 5 to increase the heat exchange area and improve heat exchange efficiency. A separation box 8 is fixedly connected to the upper rear of the base plate 1, used to remove impurities from the waste gas. Two filters 9 are fixedly connected inside the separation box 8. The filters 9 are used to separate and filter solid particles in the exhaust gas. Two rack plates 10 are fixedly connected to the bottom of the separation box 8. The rack plates 10 drive the gear 18 to rotate by meshing with the gear 18. A top frame 11 is fixedly connected to the upper side of the separation box 8. The function of the top frame 11 is to support the motor 12 and other components to ensure the overall stability and safety of the device. The motor 12 is fixedly connected to the right side of the top frame 11. The motor 12 is used to provide power to drive the cleaning component to operate. A reciprocating screw 13 is fixedly connected to the output end of the motor 12. The reciprocating screw 13 is used to convert the rotational motion of the motor 12 into linear motion. A sliding block 14 is threadedly connected to the outside of the reciprocating screw 13. The sliding block 14 moves linearly by rotating the reciprocating screw 13. A connecting block 15 is fixedly connected to the bottom of the sliding block 14. The connecting block 15 is used to install the cleaning component. The cleaning component is set at the bottom of the connecting block 15. The cleaning component is used to clean the solid particles filtered or separated on the outside of the filters 9.

[0023] The cleaning assembly includes two rotating shafts 16. The upper part of the rotating shaft 16 is rotatably connected to the bottom of the connecting block 15. The rotating shaft 16 is used to ensure the smooth rotation of the cleaning roller 17. The cleaning roller 17 is fixedly connected to the outside of the rotating shaft 16. The cleaning roller 17 is used to clean the filter screen 9 and prevent clogging. The bottom of the cleaning roller 17 is fixedly connected to a gear 18.

[0024] The cleaning roller 17 and the filter screen 9 are fitted together to ensure that the cleaning roller 17 can be closely attached to the filter screen 9 to achieve the best cleaning effect. The gear 18 and the rack plate 10 are meshed. The gear 18 moves and rotates at the same time, which further drives the cleaning roller 17 to rotate.

[0025] The end of the delivery pipe 7 away from the air pump 2 passes through the heat dissipation fins 6 and is fixedly connected inside the separation box 8. While cooling the heated exhaust gas, it accurately delivers the exhaust gas into the separation box 8 for solid particle separation.

[0026] Both the connecting block 15 and the rotating shaft 16 are slidably connected to the upper wall of the separation box 8 to ensure the smooth operation of the cleaning components.

[0027] The bottom of the base plate 1 is fixedly connected to four corners with casters 20. The casters 20 facilitate the movement and fixation of the device. The bottom of the separation box 8 is fixedly connected to two collection boxes 19, which are used to collect the separated impurities for subsequent processing.

[0028] The left filter screen has a smaller mesh size than the right filter screen, thus achieving graded screening. Larger solid particles are removed first by the left filter screen, and smaller solid particles are removed by the right filter screen.

[0029] Working Principle: When it is necessary to collect oxygen-enriched exhaust gas from the nitrogen generator, the exhaust gas discharge pipe is installed on the outside of the heating shell 3, and the air pump 2 is started. The air pump 2 draws in the exhaust gas. At this time, the heating wire 4 is energized, causing it to heat up. The extracted exhaust gas passes through the heating wire 4, removing moisture from the exhaust gas, making subsequent treatment cleaner. The moisture-removed exhaust gas is then transported to the cooling box 5 through the conveying pipe 7. The heat dissipation fins 6 inside the cooling box 5 cool the heated exhaust gas to prevent damage to the device due to excessively high exhaust gas temperature. After cooling, the exhaust gas is again transported to the separation box 8 through the conveying pipe 7 for further treatment. Here, the exhaust gas first passes through the left-side filter screen 9 to remove larger solid particles. After initial filtration, the air passes through the right-side filter 9 to remove smaller solid particles from the exhaust gas. However, after prolonged filtration, the filter 9 accumulates a large number of solid particles, causing blockage and reducing the separation efficiency. At this point, the motor 12 is activated, which in turn drives the reciprocating screw 13 to rotate. The reciprocating screw 13 then drives the sliding block 14 to slide, which in turn drives the connecting block 15 to slide. The sliding of the connecting block 15 in turn drives the rotating shaft 16 and the cleaning roller 17 to slide, cleaning the outer side of the filter 9. As the rotating shaft 16 slides, it also drives the gear 18 to slide. Since the gear 18 meshes with the rack plate 10, it also rotates as it slides, further driving the cleaning roller 17 to rotate and increasing the cleaning effect.
