Description

Technical Field

[0001] The invention belongs to the technical field of nitrogen generators, and in particular relates to a nitrogen generator with a dust filtering function. Background Art

[0002] The pressure swing adsorption nitrogen generator uses air as raw material and high-quality carbon molecular sieve as adsorbent. It uses the principle of pressure swing adsorption and molecular sieves full of micropores to selectively adsorb air to achieve the purpose of oxygen and nitrogen separation. The air entering the input end of the existing nitrogen generator will contain a certain amount of dust. If the dust enters the nitrogen generator without being treated, it will affect the safety and service life of the components inside the nitrogen generator. Therefore, it is necessary to set a dust filtration mechanism on the basis of the nitrogen generator to improve the purity of the air entering the nitrogen generator.

[0003] Patent No. CN118718642B discloses a nitrogen generator with a dust filtering function, specifically relates to the technical field of nitrogen generators, including a base, a nitrogen generator body is fixedly installed at the rear of the upper end of the base, a dryer is fixedly installed in the middle of the upper end of the base, a connecting pipe 1 is fixedly connected to the upper end of the dryer and the upper end of the nitrogen generator body, and a filter box is fixedly connected to the front of the upper end of the base. The nitrogen generator with a dust filtering function described in the present invention is provided with a filter assembly, so that after the air enters the inner cavity of the filter box, it can perform multiple filtering operations to achieve a combination of dry and wet methods, and at the same time, it can more comprehensively separate and filter the oil content of the dust in the air, capture dust, particulate matter, ammonia, hydrogen sulfide and other harmful substances in the air, effectively purify the air, and reduce the temperature of the air, so as to better meet the needs of nitrogen production, improve the purity of subsequent nitrogen production operations, reduce the loss of the nitrogen generator body, and reduce the operating cost.

[0004] In the prior art, the air is filtered multiple times by setting a filter assembly to improve the purity of the air, but the overall use still has the following problems: First, when existing dust filtering devices filter the air, the air pressure is relatively high, resulting in excessive wind speed, which not only causes the equipment to vibrate and make noise, but also causes significant wear on the filter components, allowing high-speed airflow with impurities to pass through the filter material, affecting the service life of the filter material.

[0005] Secondly, when the existing device filters the air, larger particles will clog the surface of the filter material and cannot be effectively cleaned. The filter material needs to be replaced and cleaned many times, which affects work efficiency.

[0006] Finally, the existing filtering device also uses water mist to reduce dust in the air. When the air is compressed and enters the interior of the filtering device, the air passing efficiency cannot be adjusted adaptively, resulting in the area where the air passes being too concentrated and unable to evenly contact the water mist, resulting in a weakened dust reduction effect. Summary of the invention

[0007] In order to overcome the shortcomings of the prior art, the present invention provides a nitrogen generator with a dust filtering function. By arranging a first impeller and a filter plate and other structures, not only can the filter plate be scraped and cleaned in time to increase the service life of the filter plate, but also the air pressure can be used as a power source to reduce energy loss.

[0014] Preferably, a guide ring is provided at one end of the plurality of connecting rings.

[0015] This arrangement can guide the air through the inclined inner circular surface of the guide ring, and guide the air to the vicinity of the second air inlet, so as to facilitate the passage of air and the entry of air into the interior of the connecting ring.

[0026] In summary, compared with the prior art, the beneficial effects of this solution are: (1) The present invention provides a first impeller and a transmission rod as well as a first scraper and a filter plate. When air enters the first filter chamber, the air pushes the first impeller in contact with the first impeller to rotate, so that the first impeller drives the first scraper to rotate through the transmission rod to clean the surface of the filter plate. This configuration can not only scrape and clean the filter plate in time and increase the service life of the filter plate, but also use the air pressure as a power source to reduce energy loss. At the same time, the diameter of the expanded pipe is larger than that of the first air inlet. The wind speed of air entering the larger diameter area from the smaller diameter area will be weakened, and will be further weakened by contacting the first impeller.

(2) The present invention provides an inclined block and a connecting ring as well as a second air inlet and a supporting frame. After the first impeller drives the transmission rod to rotate, the transmission rod can drive the connecting ring to rotate through the rotating disk, so that the wind entering the connecting ring can throw out the particles through centrifugal force, thereby performing preliminary filtration on the air. The rotating disk can block the impurities separated by the air, prevent secondary dust from affecting the filtration efficiency, and prevent the air from directly contacting the filter plate, preventing the impurities with particles from damaging the filter plate, thereby further improving the service life of the filter plate.

[0027] (3) The present invention provides a diverter tube and a guide block as well as air holes and a reset spring. After preliminary filtration, the gas will enter the interior of the second filter chamber. By providing a diverter tube and a plurality of air holes, the air can be evenly diverted inside the second filter chamber, thereby fully mixing and reacting with the water mist inside the second filter chamber, so that the dust particles in the air absorb water and settle. By providing a guide block, when the wind pressure is large, the air will push the plurality of guide blocks to slide outward, thereby increasing the number of air holes, improving the air passing efficiency, and at the same time, the air can be evenly diverted inside the second filter chamber, thereby improving the dust reduction effect.

[0028] (4) The present invention provides a second impeller, a second scraper, a third scraper, a sewage outlet and other structures. After the air enters the interior of the second filter chamber, it will blow the second impeller, thereby driving the plurality of second scrapers to scrape and clean the inner wall of the second filter chamber. This arrangement can not only clean the inner wall of the second filter chamber and discharge the sewage and impurities inside the second filter chamber into the interior of the sealing ring, but also use air as a power source to reduce energy loss, making the device more environmentally friendly.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment 1: refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A nitrogen generator with dust filtering function includes a nitrogen generator body 10. A dryer 11 is arranged at the air inlet duct of the nitrogen generator body 10. The dryer 11 can dry the filtered air. This is a prior art and will not be elaborated in detail herein. A first filter cabin 12 is arranged at the air inlet of the dryer 11. The first filter cabin 12 is annular as a whole. An expansion pipe 17 is arranged at one end of the first filter cabin 12. The expansion pipe 17 is hemispherical, and a first air inlet 16 is arranged at one end of the expansion pipe 17. The diameter of the first air inlet 16 is smaller than the maximum diameter of the expansion pipe 17. The air is directly When the area with a smaller diameter enters the area with a larger diameter, the wind speed will weaken. Slowing down the wind speed can reduce the noise generated by the vibration of the device, and the air speed is reduced, which is convenient for filtering the air and reducing the wear of the filter material. A support frame 20 is provided inside the first filter cabin 12, and a transmission rod 54 is rotatably provided inside the support frame 20. A first impeller 18 is provided at one end of the transmission rod 54. The first impeller 18 is located at one end close to the first air inlet 16. The first impeller 18 contacts the air, which can further reduce the wind speed. In addition, the first impeller 18 can drive the transmission rod 54 to rotate. At the same time, a filter plate 24 is provided at the other end of the transmission rod 54. A convex ring 23 is provided on the outer circumferential surface of the filter plate 24. The convex ring 23 is fixedly connected to the inner circumferential surface of the first filter cabin 12. A rotating rod 22 is provided on the outer circumferential surface of the transmission rod 54. A first scraper 25 is provided on one side of the rotating rod 22. The first scraper 25 abuts against the surface of the filter plate 24 to scrape the filter plate 24 and reduce the accumulation of impurities on the surface of the filter plate 24.

[0032] For further reference, Figure 5 and Figure 6 A rotating disk 29 is provided on the outside of the transmission rod 54, and a plurality of connecting rings 27 are provided on the outer surface of the rotating disk 29. A second air inlet 28 is provided between the plurality of connecting rings 27. An inclined block 26 is provided at one end of each of the plurality of connecting rings 27. One end of the inclined block 26 is inclined in the opposite direction away from the connecting ring 27. A guide ring 21 is provided at one end of the plurality of connecting rings 27. The inner circular surface of the guide ring 21 is in the shape of a cone hole and is wide open toward the direction of the first air inlet 16. This arrangement can guide the air through the inclined inner circular surface, and guide the air to the vicinity of the second air inlet 28. The air entering the connecting ring 27 through the second air inlet 28 will be thrown onto the inner wall of the first filter cabin 12 by centrifugal force after the connecting ring 27 rotates at a high speed, thereby reducing impurities with larger particles in the air and preventing impurities from damaging the filter plate 24. The impurities separated by the centrifugal force remain between the filter plate 24 and the guide ring 21.

[0033] For further reference, Figure 3 and Figure 7A slag discharge port is provided on the inner circumferential surface of the first filter chamber 12 between the filter plate 24 and the guide ring 21, a piston 44 is slidably provided inside the slag discharge port, one end of the piston 44 is inclined, and a sealing ring 43 is provided at the notch of the slag discharge port, the sealing ring 43 abuts against one end of the piston 44 to form a seal to prevent air leakage, a connecting rod 45 is provided at the bottom of the piston 44, two limit springs 47 are provided on the end surface of the connecting rod 45, one end of the two limit springs 47 are fixedly connected to the bottom end surface of the piston 44, one end of the connecting rod 45 is provided with two protrusions, the outside of the two protrusions is slidably provided with a slide rail 46, the protrusion is slidably connected to the slide rail 46, one end of the slide rail 46 is provided, the outside of the driving rod 48 is provided with a collection box 52 on the outer circumferential surface of the first filter chamber 12, the driving rod 48 is slidably connected to the collection box 52, and a handle is provided at one end of the driving rod 48; By pulling the handle, the driving rod 48 slides and pulls the slide rail 46 to move, so that the slide rail 46 drives the connecting rod 45 at the top to move, and the connecting rod 45 drives the piston 44 to move at the same time. The inclined surface of the piston 44 abuts against the notch of the slag discharge port. Because the inclined surface of the piston 44 is abutted by the notch, and because of the pulling force of the driving rod 48, the piston 44 moves downward and squeezes the connecting rod 45, so that the connecting rod 45 compresses the limiting spring 47. When the piston 44 disengages from the notch, the impurities between the guide ring 21 and the filter plate 24 fall into the interior of the collection box 52 through the slag discharge port for unified collection and processing. After the collection is completed, the driving rod 48 is pushed in the opposite direction, so that the driving rod 48 pushes the connecting rod 45 and the piston 44 to move. When the piston 44 is below the slag discharge port, the limiting spring 47 recovers due to elastic potential energy and pushes the piston 44 to slide upward and abut against one side of the sealing ring 43 to form a seal. Through this arrangement, the impurities can be uniformly collected and cleaned only by pulling the driving rod 48.

[0034] For further reference, Figure 2 , Figure 3 and Figure 8 A second filter chamber 53 is provided on one side of the first filter chamber 12. The diameter of the second filter chamber 53 is greater than that of the first filter chamber 12, so as to further reduce the wind speed of the air.

A plurality of rectangular holes are provided on the outer surface of the shunt cylinder 30. A plurality of guide blocks 31 are slidably provided inside the rectangular holes. One side of the guide block 31 is an arc surface. A plurality of air holes 32 are provided on the surfaces of the plurality of guide blocks 31 and the shunt cylinder 30. By providing a plurality of air holes 32, the wind speed of the air in the flow can be reduced, thereby improving the effect of the mixing reaction between air and water mist and improving the dust reduction effect. A plurality of return springs 33 are arranged on the outside of the guide block 31, and the plurality of return springs 33 are fixedly connected to the inner circular surface of the diverter tube 30. By setting the guide block 31, when the wind pressure is relatively large, the guide block 31 can be blown to slide in all directions, and the plurality of air holes 32 on the surface of the guide block 31 are exposed to the interior of the second filter chamber 53, so that the air inside the diverter tube 30 has more air holes 32 to enter the interior of the second filter chamber 53, thereby improving the air passage efficiency. Because the inclined surface of the guide block 31 is arc-shaped, the air holes 32 diverge the air in a divergent manner, thereby improving the uniformity of the air, increasing the contact area with the water mist, and improving the dust reduction effect. A water baffle is arranged between the second filter chamber 53 and the first filter chamber 12. By setting the water baffle, the water mist can be prevented from flowing back into the interior of the first filter chamber 12, thereby improving the stability of the device.

Its main function is to use ultrasonic The water inside the water storage tank 34 is atomized, and the water storage tank 34 is pressurized by the water pump 13. The atomized water is finally sprayed out by the nozzle 57 and mixed with the air, so that the fine particles in the air absorb water and precipitate, thereby filtering the air. A funnel cabin 19 is provided on one side of the second filter cabin 53. The funnel cabin 19 is funnel-shaped as a whole. Through this arrangement, the air can be compressed through the funnel cabin 19 from the second filter cabin 53 with a larger space, thereby improving the air outlet efficiency. The funnel cabin 19 is connected to the dryer 11. After the air enters the dryer 11, the air will be dried to meet the needs of the nitrogen generator.

[0036] For further reference, Figure 2 , Figure 3 , Figure 5 , Fig.10 , Fig.11 and Fig.12Two connecting rings 36 are arranged inside the second filter cabin 53, and movable rings 37 are arranged inside the connecting rings 36. A fixing frame 49 is arranged on one side of one of the movable rings 37, and a second impeller 50 is rotatably arranged inside the fixing frame 49. The direction of the second impeller 50 is opposite to the air outlet of the shunt cylinder 30.

Through this arrangement, the second impeller 50 can drive the fixing frame 49 to rotate after rotation, so that the fixing frame 49 drives the fixing ring 51 to rotate, and drives multiple connecting rods 38 to rotate through the fixing ring 51. The connecting rod 38 drives the second scraper 39 to scrape and clean the inner circular surface of the second filter chamber 53. This arrangement can not only clean the inner circular surface of the second filter chamber 53, but also use wind pressure to generate power, reduce energy consumption, and reduce resource waste.
