Description
Technical Field
[0001] This utility model belongs to the field of nitrogen generator technology, and in particular relates to a compact container mobile nitrogen generator. Background Technology
[0002] A nitrogen generator is a device that uses air as raw material and separates oxygen and nitrogen using physical methods to obtain nitrogen gas. Industrially used nitrogen generators can be classified into three types according to different classification methods: cryogenic air separation, molecular sieve air separation, and membrane air separation, with molecular sieve air separation being the most commonly used.
[0003] For example, patent CN215364916U discloses a mobile nitrogen generator, including a base, rollers, a blower, a water filter chamber, a filter chamber, sound-absorbing cotton, a filter screen, and an air outlet pipe. The base is connected to the rollers; a handrail is provided on the end of the base away from the rollers; the blower is connected to the base on the side of the handrail; the blower outlet is connected to the air outlet pipe; the end of the air outlet pipe away from the blower is connected to the water filter chamber; and the air outlet pipe is connected to the filter chamber. This device has a simple structure and is easy to operate. It can effectively produce high-purity nitrogen. The filter chamber and water filter chamber can effectively remove dust and water-soluble gases from the air, effectively improving the purity of the nitrogen produced by this device. In the nitrogen generating chamber, the carbon molecular sieve is more likely to combine with oxygen molecules, thereby increasing the nitrogen content inside the chamber. The nitrogen can be effectively stored in a pressure tank through a pressurization device.
[0004] Existing mobile nitrogen generators typically require lifting before movement, but their excessive weight causes the rollers to retract into the support, preventing normal movement. Therefore, we propose a compact containerized mobile nitrogen generator. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned technical problems by providing a compact containerized mobile nitrogen generator, thus avoiding the problem that the nitrogen generator's excessive weight causes the rollers to suddenly retract into the support, preventing the nitrogen generator from moving normally.
[0006] In view of this, the present invention provides a compact containerized mobile nitrogen generator, including a mobile base, a screw provided on the inner wall of the mobile base, a working slider threadedly connected to the outer wall of the screw, a connecting rod screwed to both ends of the working slider, a sliding connecting plate slidably connected to the inner wall of the mobile base at one end of the connecting rod, a lifting plate fixedly connected to both ends of the sliding connecting plate, a lifting guide groove provided on the outer wall of the lifting plate, a lifting column movably connected in the groove of the lifting guide groove, a support fixedly connected to the bottom edge of the mobile base slidably connected to the outer wall of the lifting column, a roller provided at the bottom end of the lifting column, and a box installed at the top of the mobile base;
[0007] A nitrogen generator assembly, located inside the housing, is used for mixing air to generate nitrogen.
[0008] Based on the above structure, the lifting plate slides through the lifting guide groove, causing the lifting column to slide vertically along the inner wall of the support. The sliding of the lifting column causes the roller to extend to the bottom of the support, thereby lifting the mobile base. Then, the staff pushes the mobile base to the working area. The left half of the lifting guide groove is parallel to the mobile base, which helps to achieve stable support for the mobile base when it moves. This avoids the roller suddenly retracting into the support due to the excessive weight of the nitrogen generator, which would prevent the mobile base from moving normally.
[0009] Preferably, there are two sets of sliding connecting plates, and the two sets of sliding connecting plates are parallel. In this embodiment, by setting two sets of sliding connecting plates, it is beneficial for the working slider to drive the sliding connecting plates to slide along the inner wall of the movable base through the connecting rod, thereby performing extension and retraction operations on the rollers at the four corners of the bottom edge of the movable base.
[0010] Preferably, the lifting guide groove is divided into left and right parts. The left half of the lifting guide groove is parallel to the movable base, and the right half of the lifting guide groove is inclined. In this embodiment, the lifting plate slides through the lifting guide groove to drive the lifting column to slide vertically along the inner wall of the support. The sliding of the lifting column drives the roller to extend to the bottom of the support, thereby lifting the movable base. Then, the operator pushes the movable base to the working area. The left half of the lifting guide groove is parallel to the movable base, which is beneficial to achieve stable support for the movable base when it moves.
[0011] Preferably, the top edge of the movable base is provided with positioning plates at the four corners. The positioning plates of the movable base are L-shaped. In this embodiment, this facilitates the stable placement of the box on the movable base and prevents the box from detaching when the movable base is moved.
[0012] Preferably, the nitrogen generating assembly includes:
[0013] A compressed air pump is fixedly connected to the inner wall of the housing. An air suction pipe is fixedly connected to the output end of the compressed air pump. A protective net is fixedly connected to the outer wall of the air suction pipe. A connecting shaft is screwed onto the outer wall of the protective net. A fan blade is fixedly connected to one end of the connecting shaft, and a rotating plate is fixedly connected to the end of the connecting shaft away from the fan blade. A cleaning brush that fits against the outer wall of the protective net is fixedly connected to the outer wall of the rotating plate. A filter assembly is installed at the output end of the compressed air pump. A cylinder A is installed at the output end of the filter assembly. A pipe on one side of cylinder A is connected to cylinder B. Nitrogen buffer tanks are connected to the discharge ports of cylinders A and B. A mixing tank is connected to the top pipes of cylinders A and B. In this embodiment, the compressed air pump drives the mixed gas to enter the chamber through the suction pipe. A protective net is installed to perform preliminary filtration of the mixed gas. At the same time, during suction, the airflow of the mixed gas drives the fan blades to rotate. The rotation of the fan blades drives the rotating plate to rotate through the connecting shaft. The rotation of the rotating plate then drives the cleaning brush to clean the impurities on the outer wall of the protective net. Next, the mixed gas is purified by the filter assembly. The purified mixed gas is separated by cylinders A and B, which contain molecular sieves. When cylinder A adsorbs nitrogen, cylinder B desorbs other mixed gases and discharges them into the mixing tank. When cylinder B adsorbs nitrogen, cylinder A desorbs other mixed gases and discharges them into the mixing tank. The separated nitrogen enters the nitrogen buffer tank through a pipeline.
[0014] Preferably, the fan blades are parallel to the protective net. In this embodiment, by setting up the protective net, the mixed gas is initially filtered to remove large-volume impurities.
[0015] Preferably, the connecting shaft coincides with the central axis of the suction pipe. In this embodiment, the airflow of the mixed gas drives the fan blade to rotate, and the rotation of the fan blade drives the rotating plate to rotate through the connecting shaft. In turn, the rotation of the rotating plate drives the cleaning brush to clean the impurities on the outer wall of the protective net.
[0016] The beneficial effects of this utility model are:
[0017] 1. This compact containerized mobile nitrogen generator features a lifting guide groove. The lifting plate slides through the guide groove, causing the lifting column to slide vertically along the inner wall of the support. The sliding of the lifting column causes the rollers to extend to the bottom of the support, thereby lifting the mobile base. Then, the operator pushes the mobile base to the work area. The left half of the lifting guide groove is parallel to the mobile base, which helps to stably support the mobile base during movement and prevents the rollers from suddenly retracting into the support due to the excessive weight of the nitrogen generator, thus preventing the mobile base from moving normally.
[0018] 2. This compact containerized mobile nitrogen generator, through the installation of a cleaning brush, uses a compressed air pump to drive a mixed gas into the container through an intake pipe. A protective net is installed to perform preliminary filtration of the mixed gas. At the same time, during intake, the airflow of the mixed gas drives the fan blades to rotate. The rotation of the fan blades drives the rotating plate to rotate through the connecting shaft. In turn, the rotation of the rotating plate drives the cleaning brush to clean impurities on the outer wall of the protective net. Attached Figure Description

[0028] This application discloses a compact containerized mobile nitrogen generator, including a mobile base 1. A screw 2 is provided on the inner wall of the mobile base 1. A working slider 3 is threadedly connected to the outer wall of the screw 2. A connecting rod 4 is screwed to both ends of the working slider 3. A sliding connecting plate 5 that is slidably connected to the inner wall of the mobile base 1 is screwed to one end of the connecting rod 4. A lifting plate 6 is fixedly connected to both ends of the sliding connecting plate 5. A lifting guide groove 7 is provided on the outer wall of the lifting plate 6. A lifting column 8 is movably connected in the groove of the lifting guide groove 7. A support 9 that is fixedly connected to the bottom edge of the mobile base 1 is slidably connected to the outer wall of the lifting column 8. A roller 10 is provided at the bottom end of the lifting column 8. A box 11 is installed at the top of the mobile base 1.
[0029] The nitrogen generator is located inside housing 11 and is used for nitrogen generation from mixed air.
[0030] Based on the above structure, the lifting plate 6 slides through the lifting guide groove 7, causing the lifting column 8 to slide vertically along the inner wall of the support 9. The lifting column 8 slides, causing the roller 10 to extend to the bottom of the support 9, thereby lifting the movable base 1. Then, the staff pushes the movable base 1 to the working area. The left half of the lifting guide groove 7 is parallel to the movable base 1, which helps to achieve stable support for the movable base 1 when it moves, and avoids the roller 10 suddenly retracting into the support 9 due to the excessive weight of the nitrogen generator, which would prevent the movable base 1 from moving normally.
[0031] In one embodiment, two sets of sliding connecting plates 5 are provided, and the two sets of sliding connecting plates 5 are parallel.
[0032] In this embodiment, by setting two sets of sliding connecting plates 5, it is beneficial for the working slider 3 to drive the sliding connecting plates 5 to slide along the inner wall of the movable base 1 through the connecting rod 4, thereby performing extension and retraction operations on the rollers 10 at the four corners of the bottom edge of the movable base 1.
[0033] In one embodiment, the lifting guide 7 is divided into left and right parts. The left half of the lifting guide 7 is parallel to the movable base 1, and the right half of the lifting guide 7 is inclined.
[0034] In this embodiment, the lifting plate 6 slides through the lifting guide groove 7 to drive the lifting column 8 to slide vertically along the inner wall of the support 9. The lifting column 8 slides to drive the roller 10 to extend to the bottom of the support 9, thereby lifting the movable base 1. Then, the staff pushes the movable base 1 to the working area. The left half of the lifting guide groove 7 is parallel to the movable base 1, which is conducive to achieving stable support for the movable base 1 when it moves.
[0035] In one embodiment, positioning plates are provided at the four corners of the top edge of the movable base 1, and the positioning plates of the movable base 1 are L-shaped.
[0036] In this embodiment, the housing 11 is placed stably on the mobile base 1, preventing the housing 11 from detaching when the mobile base 1 is moved.
[0037] In one embodiment, the nitrogen generation assembly includes:
[0038] A compressed air pump 12 is fixedly connected to the inner wall of the housing 11. A suction pipe 13 is fixedly connected to the output end of the compressed air pump 12. A protective net 14 is fixedly connected to the outer wall of the suction pipe 13. A connecting shaft 15 is screwed onto the outer wall of the protective net 14. A fan blade 16 is fixedly connected to one end of the connecting shaft 15. A rotating plate 17 is fixedly connected to the end of the connecting shaft 15 away from the fan blade 16. A cleaning brush 18 that fits against the outer wall of the protective net 14 is fixedly connected to the outer wall of the rotating plate 17. A filter assembly 19 is installed at the output end of the compressed air pump 12. An A cylinder 20 is installed at the output end of the filter assembly 19. A B cylinder 21 is connected to one side of the A cylinder 20. A nitrogen buffer tank 22 is connected to the discharge port pipes of the A cylinder 20 and the B cylinder 21. A mixing tank 23 is connected to the top pipes of the A cylinder 20 and the B cylinder 21.
[0039] In this embodiment, the compressed air pump 12 drives the mixed gas to enter the housing 11 through the suction pipe 13. The mixed gas is initially filtered by the protective net 14. At the same time, during suction, the airflow of the mixed gas drives the fan blade 16 to rotate. The rotation of the fan blade 16 drives the rotating plate 17 to rotate through the connecting shaft 15. The rotation of the rotating plate 17 drives the cleaning brush 18 to clean the impurities on the outer wall of the protective net 14. Then, the mixed gas is purified by the filter assembly 19. The purified mixed gas is separated by the A cylinder 20 and B cylinder 21, which contain molecular sieves. When the A cylinder 20 adsorbs nitrogen, the B cylinder 21 desorbs other mixed gases and discharges them into the mixing tank 23. When the B cylinder 21 adsorbs nitrogen, the A cylinder 20 desorbs other mixed gases and discharges them into the mixing tank 23. The separated nitrogen enters the nitrogen buffer tank 22 through the pipeline.
[0040] In one embodiment, the fan blade 16 is parallel to the protective net 14.
[0041] In this embodiment, a protective net 14 is set up to perform a preliminary filtration operation on the mixed gas, filtering out large-volume impurities.
[0042] In one embodiment, the connecting shaft 15 coincides with the central axis of the suction pipe 13.
[0043] In this embodiment, the airflow of the mixed gas drives the fan blade 16 to rotate. The rotation of the fan blade 16 drives the rotating plate 17 to rotate via the connecting shaft 15. In turn, the rotation of the rotating plate 17 drives the cleaning brush 18 to clean the impurities on the outer wall of the protective net 14.
[0044] In this embodiment, the compact containerized mobile nitrogen generator is used by first lifting the mobile base 1. The operator rotates the screw 2, which drives the two sets of connecting rods 4 to move synchronously through the working slider 3. This causes the working slider 3 to drive the sliding connecting plate 5 to slide along the inner wall of the mobile base 1 through the connecting rods 4. The sliding connecting plate 5 drives the lifting plates 6 at both ends to slide synchronously. The lifting plates 6 slide through the lifting guide groove 7, which drives the lifting column 8 to slide vertically along the inner wall of the support 9. The lifting column 8 drives the roller 10 to extend to the bottom of the support 9, thereby lifting the mobile base 1. Then, the operator pushes the mobile base 1 to the working area. The left half of the lifting guide groove 7 is parallel to the mobile base 1, which helps to stably support the mobile base 1 when it moves. This prevents the roller 10 from suddenly retracting into the support 9 due to the excessive weight of the nitrogen generator, which would prevent the mobile base 1 from moving normally.
[0045] Next, the compressed air pump 12 operates to drive the mixed gas into the housing 11 through the suction pipe 13. The mixed gas is initially filtered by the protective net 14. At the same time, during suction, the airflow of the mixed gas drives the fan blade 16 to rotate. The rotation of the fan blade 16 drives the rotating plate 17 to rotate through the connecting shaft 15. In turn, the rotation of the rotating plate 17 drives the cleaning brush 18 to clean the impurities on the outer wall of the protective net 14.
[0046] Finally, the mixed gas is purified by the filter assembly 19. The purified mixed gas is separated by the A cylinder 20 and B cylinder 21, which contain molecular sieves. When the A cylinder 20 adsorbs nitrogen, the B cylinder 21 desorbs other mixed gases and discharges them into the mixing tank 23. When the B cylinder 21 adsorbs nitrogen, the A cylinder 20 desorbs other mixed gases and discharges them into the mixing tank 23. The separated nitrogen enters the nitrogen buffer tank 22 through the pipeline.
