Description

Technical Field

[0001] This utility model relates to the field of nitrogen purification technology, specifically a nitrogen purification and filtration device. Background Technology

[0002] Nitrogen is a chemically stable gas that is widely used in manufacturing, pharmaceuticals, electronics, and other fields. Depending on the purpose of use, the required concentration varies. Generally, the concentration requirements for nitrogen are not high in general industries, but some special industries have particularly high requirements, such as the electronics industry and high-requirement experiments, which put forward corresponding requirements for the purity of nitrogen. Therefore, the production and purification filtration of nitrogen are involved. Existing purification filtration devices are generally single-layer filter screens. The two ends of the purification filtration device are connected to the inlet and outlet respectively, so that nitrogen can be filtered by passing through the purification filtration device.

[0003] In a Chinese patent with publication number CN216653834U entitled "A Nitrogen Purification and Filtration Device", multiple sets of first and second filter plates arranged in a mirror-like and staggered manner inside the filter cylinder will retain nitrogen, thereby increasing the nitrogen filtration and purification time. In this way, by retaining nitrogen, the nitrogen can be fully adsorbed and filtered by activated carbon. At the same time, the large filter holes on the surface of the first and second filter plates can easily filter larger particles floating in the nitrogen, thereby further enhancing the filtration effect of nitrogen.

[0004] However, this device still has shortcomings. The method of purifying and filtering nitrogen in this device is to add multiple filter plates and activated carbon columns to complete the efficient filtration of nitrogen. However, the purification efficiency is relatively low when relying solely on filter plates and activated carbon columns. At the same time, with the long-term use of filter plates, a lot of impurities will accumulate on the surface of the filter element. When replacing the filter element, it needs to be removed and replaced one by one, which makes the replacement process slow and results in low maintenance efficiency. In order to address the above problems, the inventor proposes a nitrogen purification and filtration device to solve the above problems. Utility Model Content

[0005] To address the issues of low purification efficiency when using only filter plates and activated carbon columns for filtration, and low maintenance efficiency due to the need to remove and replace filter elements sequentially, this invention aims to provide a nitrogen purification and filtration device.

[0007] Preferably, a plurality of stirring blades are fixedly connected to the outer ring of the stirring shaft, and the plurality of stirring blades are evenly distributed, and a gear is rotatably connected to the center of the top of the filter barrel.

[0008] Preferably, three gears are rotatably connected near the center of the top of the filter barrel, and all three gears mesh with gear one. The top of the stirring shaft passes through the filter barrel and is fixedly connected to gear two.

[0009] Preferably, a support frame is fixedly connected to the center of the top of the filter barrel, and a drive motor is fixedly connected to the center of the top of the support frame. The output end of the drive motor passes through the support frame and is fixedly connected to a gear.

[0010] Preferably, a mounting base is fixedly connected to the outer ring of the filter barrel near the bottom, and an adapter is fixedly connected to the center of the side of the air inlet box away from the filter barrel.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, by running a drive motor, and then through the cooperation between gear two, gear one and stirring shaft, the problem of low purification efficiency is solved by using only filter plates and activated carbon columns for filtration and purification.

[0013] 2. In this utility model, by setting up a placement plate, and with the cooperation between the air inlet box and the mounting plate, the effect of directly replacing multiple filter structures can be achieved, thereby improving the efficiency of filter structure replacement and solving the problem of low maintenance efficiency caused by having to take out and replace the filter elements one by one when replacing them.

An air inlet pipe 11 and an air inlet box 2 are symmetrically fixedly connected to the outer ring of the filter barrel 1 near the center. A placement groove 21 is opened at the center of the top of the air inlet box 2. A placement plate 22 is detachably connected to the top of the air inlet box 2 and located at the placement groove 21. An installation plate 23 is detachably connected to the center of the bottom of the placement plate 22. A filter plate 1 24 is fixedly connected to the bottom of the installation plate 23 near one side. A filter plate 25 is fixedly connected to the bottom of the installation plate 23 near the filter plate 1 24. A filter plate 3 26 is fixedly connected to the bottom of the installation plate 23 near the filter plate 25. A filter plate 4 27 is fixedly connected to the bottom of the installation plate 23 near the filter plate 3 26.

[0022] Several stirring blades 33 are fixedly connected to the outer ring of the stirring shaft 32, and the stirring blades 33 are evenly distributed.

[0023] By adopting the above technical solution, the stirring blades 33 are set on the outer ring of the stirring shaft 32 in order to achieve the stirring of the inside of the filter barrel 1.

[0024] Gear 3 is rotatably connected at the center of the top of filter barrel 1.

[0025] By adopting the above technical solution, a gear 3 is rotated at the center of the top of the filter barrel 1 in order to drive three meshing gears 31.

[0026] Three gears 31 are rotatably connected at the top of the filter barrel 1 near the center, and all three gears 31 mesh with gear 3. The top of the stirring shaft 32 passes through the filter barrel 1 and is fixedly connected to the gears 31.

[0027] By adopting the above technical solution, three gears 2 31 are set so that they can be driven to rotate simultaneously with the cooperation of gear 1 3.

[0028] A support frame 34 is fixedly connected to the center of the top of the filter barrel 1.

[0029] By adopting the above technical solution, a support frame 34 is set at the center of the top of the filter barrel 1 in order to support and fix the drive motor 35.

[0030] A drive motor 35 is fixedly connected to the center of the top of the support frame 34, and the output end of the drive motor 35 passes through the support frame 34 and is fixedly connected to the gear 3.

[0031] By adopting the above technical solution, the drive motor 35 is operated, thereby causing the fixedly connected gear 3 to rotate.

[0036] Working principle: When in use, nitrogen gas is introduced through the air inlet box 2 and the adapter. The nitrogen gas filters the dust through filter plates 24, 25, 26, and 27 and enters the filter barrel 1. Hydrogen gas is introduced into the filter barrel 1 through the air inlet pipe 11. Then, the drive motor 35 is turned on to start working. The drive motor 35 drives gear 3 to rotate. Subsequently, the meshing gear 31 drives the three stirring shafts 32 to rotate. Together with multiple sets of stirring blades 33, the gas inside the filter barrel 1 is mixed. This allows hydrogen and nitrogen to mix and react quickly, thereby improving the filtration and purification efficiency of nitrogen.

[0037] When multiple filter structures need to be cleaned or replaced, the placement plate 22 on the air intake box 2 can be removed, and the multiple filter structures inside the air intake box 2 can be taken out after removing the placement plate 22. Then, the fixing mounting plate 23 below the placement plate 22 can be removed, and then the new mounting plate 23 and filter structures can be installed below the placement plate 22. This achieves the effect of directly replacing multiple filter structures, thereby improving the efficiency of filter structure replacement.
