Abstract
Description
Technical Field
[0001] This invention relates to the field of nitrogen generation equipment technology, specifically to a nitrogen generation device that is easy to clean. Background Technology
[0002] Nitrogen generators play a vital role in modern industrial production and numerous other fields. Whether it's for gas protection in the chemical industry's reaction environment, the nitrogen requirements for high-precision production environments in the electronics industry, or the application in the food industry for food preservation and extending shelf life, nitrogen generators provide strong support for the production and development of various industries.
[0003] Existing nitrogen generation equipment mainly produces nitrogen based on various principles, such as pressure swing adsorption (PSA) and membrane separation. However, these nitrogen generation devices inevitably face a series of cleaning challenges during long-term operation.
[0004] On the one hand, the gases to be treated often contain various impurities, such as dust, water vapor, oil, and other tiny particles. When these gases enter the nitrogen generator, these impurities gradually accumulate on the key components inside the equipment. Taking molecular sieves as an example, as the core component for gas separation in the nitrogen generation process, a large amount of impurities adhering to their surface will severely affect their adsorption and separation performance. The accumulation of impurities will clog the microporous structure of the molecular sieve, preventing gas molecules from passing through smoothly, thereby reducing the efficiency and purity of nitrogen production. Over time, this may also lead to molecular sieve failure, requiring frequent replacement, increasing production costs and maintenance workload.
[0005] On the other hand, filtration devices are also susceptible to impurities. During the initial filtration of gas, impurities trapped by the filtration device accumulate on components such as the filter plates. This not only reduces the filtration efficiency, increasing the impurity content of the gas entering the molecular sieve and further burdening it, but it can also cause blockage of the filtration device, affecting the normal flow of gas and consequently impacting the operational stability of the entire nitrogen generator.
[0006] In summary, existing nitrogen generation equipment has many shortcomings in terms of cleanliness, failing to meet the demands for efficient, stable, and sustainable production. Therefore, we propose a nitrogen generation device that is easy to clean, thereby improving the performance of nitrogen generation equipment, reducing maintenance costs, extending equipment lifespan, and ensuring stable production across various industries.

Through the cooperation of the filter plate 601 and the cleaning plate 603... The system can clean the inner wall of the tank 1 while filtering the gas. A transmission device 7 is movably installed below the molecular sieve 5. The transmission device 7 includes a transmission rod 701 movably installed below the inner wall of the tank 1. Several transmission plates 702 are evenly distributed on the side of the transmission rod 701. A scraper 708 is fixedly installed below the transmission plate 702, contacting the upper part of the partition 9. A vertical plate 709 is installed below the scraper 708, contacting the inner wall of the conical groove for cleaning dirt on the partition 9.

A reciprocating screw 704 is fixedly installed above the transmission rod 701, and an insert rod 7 is fixedly installed above the reciprocating screw 704. 05. A connecting plate 706 is fixedly provided on the upper surface of the reciprocating screw 704. The connecting plate 706 has symmetrical transmission grooves 707 on its side. A cleaning device 8 is movably provided on the upper surface of the transmission device 7.

A cleaning rod 802 is fixedly provided at one end of the cleaning bevel gear 801.

The cleaning slide rail 805 is fixedly installed on the inner wall of the tank 1 to ensure the stable movement of the cleaning rod 802.
[0021] The specific implementation process is as follows: First, the nitrogen generator tank 1 is installed in a suitable position using the fixing device 2. The fixing ring 201 is fixed to the surface of the tank 1. Then, the fixing rod 202 is connected to the fixing ring 201. Finally, the fixing plate 203 is fixed to the ground or other supporting surface to ensure the stability of the tank 1. The gas to be treated enters the tank 1 through the inlet pipe 3. First, the gas passes through the filter device 6. The filter plate 601 performs preliminary filtration of impurities in the gas. The filter shaft 602, driven by the reciprocating screw 704, causes the filter plate 601 to move... The repeated up-and-down motion allows the cleaning plate 603 to more thoroughly clean the inner wall of the tank 1. The gas, after preliminary filtration, flows upward and reaches the molecular sieve 5. The molecular sieve 5 adsorbs and separates the gas to obtain nitrogen, which is discharged through the outlet pipe 4. During the gas flow in the inlet pipe 3, the impeller 703 drives the transmission rod 701 to rotate under the action of the gas. The transmission plate 702 on the transmission rod 701 rotates accordingly, which in turn drives the scraper 708 and the vertical plate 709 to clean the baffle 9. The dirt flows through the conical groove to the drain outlet. 10. The filter plates are concentrated and discharged simultaneously. Meanwhile, the transmission rod 701 rotates, driving the reciprocating screw 704 to rotate, thus causing the filter plate 601 to move up and down. The connecting plate 706 is fixedly installed at one end above the reciprocating screw 704. Through the transmission groove 707 on the connecting plate 706, the cleaning bevel gear 801 rotates. The cleaning bevel gear 801 meshes with the fixed bevel gear 501, causing the cleaning rod 802 to rotate. The brush 803 cleans the surface of the molecular sieve 5, and the cleaning roller 804 rolls on the cleaning slide rail 805, ensuring the cleaning rod 802 rotates. The stable movement of the 02 brush, while the brush 803 rotates, repeatedly strikes the molecular sieve 5, generating impact force and causing the molecular sieve 5 to vibrate, thus cleaning the molecular sieve 5 and preventing it from clogging. Meanwhile, as the filter plate 601 moves up and down according to the reciprocating screw 704, when the filter plate 601 moves to the top, the brush 803 contacts the filter plate 601 during rotation, cleaning the filter plate 601 and preventing it from clogging with the molecular sieve 5.
[0022] Working Principle: First, the nitrogen generator tank 1 is installed in a suitable position using the fixing device 2. The fixing ring 201 is fixed to the surface of the tank 1. Then, the fixing rod 202 is connected to the fixing ring 201. Finally, the fixing plate 203 is fixed to the ground or other supporting surface to ensure the stability of the tank 1. The gas to be treated enters the tank 1 through the inlet pipe 3. First, the gas passes through the filter device 6. The filter plate 601 performs preliminary filtration of impurities in the gas. The filter shaft 602, driven by the reciprocating screw 704, causes the filter plate 601 to move to a certain extent, enhancing the filtration effect. At the same time, the cleaning plate 603 cleans the inner wall of the tank 1. The gas that has undergone preliminary filtration flows upward and reaches the molecular sieve 5. The molecular sieve 5 adsorbs and separates the gas to obtain nitrogen. The nitrogen is discharged through the outlet pipe 4. During the gas flow, the impeller 703 moves the gas... Under the action of the transmission rod 701, the transmission plate 702 on the transmission rod 701 rotates accordingly, which in turn drives the scraper 708 and the vertical plate 709 to clean the partition 9. The dirt is concentrated and discharged through the conical groove to the drain port 10. At the same time, the rotation of the transmission rod 701 drives the reciprocating screw 704 to rotate, which drives the cleaning bevel gear 801 to rotate through the transmission groove 707 on the connecting plate 706. The cleaning bevel gear 801 meshes with the fixed bevel gear 501, causing the cleaning rod 802 to rotate. The brush 803 cleans the surface of the molecular sieve 5, and the cleaning roller 804 rolls on the cleaning slide rail 805 to ensure the stable movement of the cleaning rod 802. In summary, the nitrogen generator of the present invention, which is easy to clean, achieves efficient cleaning of the inside of the equipment through reasonable structural design, improves the working performance and service life of the nitrogen generator, and has good application prospects.
