Description

Technical Field

[0001] This utility model relates to the field of nitrogen generator carbon molecular sieve maintenance technology, specifically to a maintenance mechanism for nitrogen generator carbon molecular sieves. Background Technology

[0002] The carbon molecular sieve in the nitrogen generator is an excellent non-polar carbon material. The carbon molecular sieve is used to separate air and enrich nitrogen. It adopts a room temperature low-pressure nitrogen production process, which has the advantages of lower investment cost, faster nitrogen production speed and lower nitrogen cost compared with the traditional cryogenic high-pressure nitrogen production process.

[0003] Existing carbon molecular sieves are prone to pulverization after prolonged use. To ensure timely detection, nitrogen detectors are often used to check the purity of nitrogen. When the purity is lower than required, the nitrogen detector alarms, reminding operators to inspect the carbon molecular sieve. However, existing nitrogen detectors are directly connected to pipes. When the carbon molecular sieve pulverizes, particles in the gas can easily enter the connecting pipe of the nitrogen detector, affecting the flow of the pipeline and even causing blockages.

[0004] Therefore, a maintenance mechanism for carbon molecular sieves used in nitrogen generators is proposed to solve the problems mentioned above. Utility Model Content

This mechanism solves the problem of existing carbon molecular sieves easily pulverizing after prolonged use. To ensure timely detection, nitrogen detectors are typically used to check nitrogen purity. When the purity is below the required level, the detector alarms, alerting operators to inspect the carbon molecular sieve. However, existing nitrogen detectors are directly connected via pipes. When the carbon molecular sieve pulverizes, particles in the gas can easily enter the detector's connecting pipe, affecting flow and even causing blockages.

[0013] Compared with the prior art, this utility model provides a maintenance mechanism for carbon molecular sieves in nitrogen generators, which has the following beneficial effects: The connecting pipe connects to the nitrogen pipeline of the nitrogen generator. After the nitrogen enters the dust collection box, it is filtered through a filter screen to prevent dust mixed in with the nitrogen from entering the nitrogen detector, affecting the air intake of the pipeline, preventing blockage, and avoiding affecting the accuracy of the detection. During use, vibration causes dust on the filter screen to fall into the dust collection box.

Mounting base 4 is fixedly connected to the inside of connecting box 3. Filter screen 5 is slidably connected to the inside of mounting base 4. Dust collection box 6 is fixedly connected to one side of filter screen 5. First inclined surface 7 is provided on both sides of the inner cavity of dust collection box 6. Second inclined surface 8 is provided on one side of the inner cavity of dust collection box 6. Third inclined surface 9 is provided on the other side of the inner cavity of dust collection box 6.

[0019] The connecting pipe 10 is connected to the nitrogen pipeline of the nitrogen generator. After the nitrogen enters the dust collection box 6, it is filtered by the filter screen 5 to prevent dust mixed in with the nitrogen from entering the nitrogen detector 1, affecting the air intake of the pipeline, preventing blockage, and avoiding affecting the accuracy of the detection. During use, vibration causes the dust on the filter screen 5 to fall into the dust collection box 6. The first inclined surface 7, the second inclined surface 8, and the third inclined surface 9 can guide the dust, allowing the dust to enter the dust collection box 6 for storage, preventing the dust from being placed in the connecting box 3, which would be inconvenient to clean.

[0020] Furthermore, an installation mechanism is provided on the outside of the connecting box 3. The installation mechanism includes a mounting bracket 11, a baffle 12, a first buckle 13, a back plate 14, an insert plate 15, a second buckle 16, and a slot 17. The mounting bracket 11 is fixedly connected to the outside of the connecting box 3. The baffle 12 is located on one side of the connecting box 3. The first buckle 13 is integrally formed and connected to the outside of the baffle 12. The back plate 14 is located on the back of the connecting box 3. The insert plate 15 is integrally formed on the outside of the back plate 14. The second buckle 16 is integrally formed and connected to the side of the back plate 14. The slot 17 is opened on the outside of the mounting bracket 11.

[0021] After installing the filter screen 5, slide the first buckle 13 of the baffle 12 into the mounting bracket 11, and ensure the connection is sealed by the sealing gasket. Then, insert the insert plate 15 of the back plate 14 between the first buckle 13 and the connecting box 3 to limit the first buckle 13. At this time, the second buckle 16 engages with the slot 17. The insert plate 15 can prevent the first buckle 13 from deforming, ensuring the stable installation of the baffle 12, thereby limiting and fixing the baffle 12 for the second time, and making it more convenient to replace and clean the filter screen 5.

[0022] Furthermore, the first buckle 13 slides through and inserts into the mounting bracket 11, and a sealing gasket is provided at the connection between the baffle 12 and the connecting box 3.

[0025] For better detection, the top of the nitrogen detector 1 is integrally formed with fins 18. A mounting bracket 19 is fixedly connected to the top of the nitrogen detector 1. A fan 20 is fixedly connected to the inner side of the mounting bracket 19 through a support. The fan 20 and the fins 18 dissipate heat from the nitrogen detector 1 to prevent the nitrogen detector 1 from overheating and causing unstable detection data.

[0026] Furthermore, a protective net 21 is fixedly connected to the top of the mounting bracket 19, and the fins 18 are evenly distributed on the top of the housing of the nitrogen detector 1.

[0027] The working principle of the above embodiment is as follows: the connecting pipe 10 is connected to the nitrogen pipeline of the nitrogen generator. After the nitrogen enters the dust collection box 6, it is filtered by the filter screen 5 to prevent dust mixed in with the nitrogen from entering the nitrogen detector 1, affecting the air intake of the pipeline, preventing blockage, and avoiding affecting the accuracy of the detection. During use, vibration causes dust on the filter screen 5 to fall into the dust collection box 6. The setting of the first inclined surface 7, the second inclined surface 8, and the third inclined surface 9 can guide the dust, allowing the dust to enter the dust collection box 6 for storage, preventing the dust from being placed in the connecting box 3, which is inconvenient for cleaning. After step 5, slide the first buckle 13 of the baffle 12 into the mounting bracket 11, and ensure the connection is sealed by the sealing gasket. Then, insert the insert plate 15 of the back plate 14 between the first buckle 13 and the connecting box 3 to limit the first buckle 13. At this time, the second buckle 16 engages with the slot 17. The insert plate 15 can prevent the first buckle 13 from deforming, ensuring the stable installation of the baffle 12, thereby limiting and fixing the baffle 12 for the second time. It is also more convenient to replace and clean the filter 5. The model of the nitrogen detector 1 is KY-2N.
