Description

Technical Field

[0001] The invention relates to the technical field of nitrogen production equipment, in particular to nitrogen production equipment which is easy to clean. Background Art

[0002] In today's industrial production and many fields, nitrogen generation equipment plays a vital role. Whether it is the gas protection of the reaction environment in the chemical industry, the demand for nitrogen in the high-precision production environment in the electronics industry, or the application of food preservation and shelf life extension in the food industry, nitrogen generation equipment provides strong support for the production and development of various industries.

[0003] Existing nitrogen production equipment mainly produces nitrogen based on a variety of principles, such as pressure swing adsorption, membrane separation, etc. However, these nitrogen production equipment inevitably face a series of cleaning problems during long-term operation.

[0004] On the one hand, the gas to be treated often contains various impurities, such as dust, water vapor, oil and other tiny particles. When these gases enter the nitrogen production equipment, the impurities will gradually accumulate on the key components inside the equipment. Take molecular sieves as an example. As the core component for achieving gas separation in the nitrogen production process, once a large amount of impurities adhere to its surface, it will seriously affect its adsorption and separation performance. The accumulation of impurities will block the microporous structure of the molecular sieve, making it impossible for gas molecules to pass smoothly, thereby reducing the efficiency and purity of nitrogen production. If this continues for a long time, it may also cause the molecular sieve to fail and need to be replaced frequently, increasing production costs and maintenance workload.

[0005] On the other hand, the filter device is also susceptible to the influence of impurities. When the filter device performs preliminary filtration on the gas, the intercepted impurities will continue to accumulate on the filter plate and other components. This will not only reduce the filtration effect, increase the impurity content of the gas that subsequently enters the molecular sieve, further increase the burden on the molecular sieve, but also may cause the filter device to be blocked, affecting the normal circulation of the gas, and further affecting the operating stability of the entire nitrogen production equipment.

[0006] In summary, the existing nitrogen production equipment has many deficiencies in terms of cleaning and cannot meet the needs of efficient, stable and sustainable production. Therefore, we propose a nitrogen production equipment that is easy to clean, so as to improve the performance of nitrogen production equipment, reduce maintenance costs, extend the service life of equipment and ensure stable production in various industries.

[0032] The specific implementation process is as follows:

[0033] First, the tank body 1 of the nitrogen production equipment is installed in a suitable position through the fixing device 2. The fixing ring 201 is fixed on the surface of the tank body 1, then the fixing rod 202 is connected to the fixing ring 201, and finally the fixing plate 203 is fixed on the ground or other supporting surfaces to ensure the stability of the tank body 1. The gas to be processed enters the interior of the tank body 1 through the intake pipe 3. First, the gas passes through the filtering device 6, and the filter plate 601 preliminarily filters the impurities in the gas. Driven by the reciprocating lead screw 704, the filter shaft 602 makes the filter plate 601 perform a certain up-and-down reciprocating movement, so that the cleaning plate 603 can clean the inner wall of the tank body 1 more comprehensively. The gas after preliminary filtration flows upward to reach the molecular sieve 5. The molecular sieve 5 adsorbs and separates the gas to obtain nitrogen, and the nitrogen is discharged through the outlet pipe 4. During the flow of the gas in the intake pipe 3, the wind wheel 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, and then drives the scraper 708 and the vertical plate 709 to clean the partition plate 9. The dirt is concentrated and discharged to the sewage outlet 10 through the conical groove. At the same time, the rotation of the transmission rod 701 drives the reciprocating lead screw 704 to rotate, so that the filter plate 601 moves up and down. The connecting plate 706 is fixedly installed at one end above the reciprocating lead screw 704, and 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, so that the cleaning rod 802 rotates, and the brush 803 cleans the surface of the molecular sieve 5. The cleaning roller 804 rolls on the cleaning slide rail 805 to ensure the stable movement of the cleaning rod 802. At the same time, during the rotation of the brush 803, it repeatedly strikes the molecular sieve 5 to generate an impact force, causing the molecular sieve 5 to vibrate and cleaning the molecular sieve 5 to prevent the molecular sieve 5 from being blocked. Also, because the filter plate 601 moves up and down according to the reciprocating lead screw 704, when the filter plate 601 moves to the topmost position, the brush 803 contacts the filter plate 601 during rotation, cleans the filter plate 601, strikes and vibrates, and cleans the filter plate 601 to prevent the filter plate 601 and the molecular sieve 5 from being blocked.

[0034] Working principle: First, the tank body 1 of the nitrogen production equipment is installed in a suitable position through the fixing device 2. The fixing ring 201 is fixed on the surface of the tank body 1, then the fixing rod 202 is connected to the fixing ring 201, and finally the fixing plate 203 is fixed on the ground or other supporting surfaces to ensure the stability of the tank body 1. The gas to be processed enters the interior of the tank body 1 through the air inlet pipe 3. First, the gas passes through the filtering device 6. The filter plate 601 preliminarily filters the impurities in the gas. Driven by the reciprocating lead screw 704, the filter shaft 602 makes the filter plate 601 move to a certain extent, enhancing the filtering effect. At the same time, the cleaning plate 603 cleans the inner wall of the tank body 1. The gas after preliminary filtration flows upward to reach the molecular sieve 5. The molecular sieve 5 adsorbs and separates the gas to obtain nitrogen, and the nitrogen is discharged through the air outlet pipe 4. During the gas flow process, the wind wheel 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, and then drives the scraper 708 and the vertical plate 709 to clean the partition plate 9. The dirt is concentrated and discharged to the sewage outlet 10 through the conical groove. At the same time, the rotation of the transmission rod 701 drives the reciprocating lead screw 704 to rotate, and 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. The cleaning roller 804 rolls on the cleaning slide rail 805 to ensure the stable movement of the cleaning rod 802. To sum up, the nitrogen production equipment with easy cleaning realizes the efficient cleaning of the interior of the equipment through reasonable structural design, improves the working performance and service life of the nitrogen production equipment, and has good application prospects.
