Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to carbon-carried nitrogen purification equipment. Background Art

[0002] Carbon-supported deoxygenation uses carbon supported by a catalyst to convert oxygen in nitrogen into carbon dioxide at a relatively low temperature, and then removes the carbon dioxide to obtain high-purity nitrogen.

[0003] In the carbon-supported deoxygenation reaction, chemical bonds are often broken and formed, which involves energy changes, usually in the form of heat; therefore, the nitrogen needs to be cooled after deoxygenation.

[0004] During cooling, it is often necessary to place the nitrogen delivery pipe into the coolant for cooling. However, during the cooling process, impurities carried in the coolant will adhere to the nitrogen input pipe, affecting the cooling effect.

[0005] The utility model designs a carbon-supported nitrogen purification device capable of automatically scraping off impurities on a nitrogen delivery pipeline to solve the above problems. Utility Model Content

[0006] Based on this, it is necessary to provide a carbon-loaded nitrogen purification equipment to address the problems existing in the current nitrogen generator purification. The output nitrogen is cooled by designing a cooling device. A slide plate is arranged in the cooling device. By controlling the sliding of the slide plate, on the one hand, impurities attached to the nitrogen output pipe of the output nitrogen can be scraped off. On the other hand, the sliding of the slide plate can promote the coolant, so that the coolant flows and increases the cooling effect.

[0007] The above purpose is achieved through the following technical solutions:

[0009] The deoxygenation purification device is equipped with an air inlet pipe for inputting air and a nitrogen outlet pipe for outputting nitrogen. The deoxygenation purification device is used for purifying nitrogen.

[0011] In one of the embodiments, a guide rod is fixedly installed in the cooling box, a connecting plate and a transmission plate are fixedly installed on the slide plate, and the transmission plate and the connecting plate are slidably matched with the guide rod.

[0012] In one of the embodiments, a screw is fixedly mounted on the output shaft of the motor, a threaded sleeve is fixedly mounted on the transmission plate, and the screw and the threaded sleeve are threadedly connected.

[0013] In one of the embodiments, two sections of coolant pipes are fixedly installed on both sides of the cooling box, the lower ends of the coolant pipes are located on the bottom sides of the cooling box, and the upper ends of the coolant pipes are located on the upper side of the cooling box.

[0014] In one embodiment, two heat exchangers are installed on both sides of the cooling box, and two sections of coolant pipes are connected to the two heat exchangers.

[0015] The beneficial effect of the utility model is that the output nitrogen is cooled by designing a cooling device, and a slide plate is arranged in the cooling device.

[0024] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0025] like Figure 1 -like Figure 5 As shown, a carbon-supported nitrogen purification device includes a deoxygenation purification device 1, such as Figure 1 , 2 As shown, the deoxygenation purification device 1 is equipped with an air inlet pipe 2 for inputting air and a nitrogen outlet pipe 3 for outputting nitrogen. The deoxygenation purification device 1 is used for purifying nitrogen; Figure 3 , 4 As shown, the cooling device 4 is used to cool the purified nitrogen, which includes a cooling box 403, a slide plate 404, and a motor 405, wherein the nitrogen output pipe 3 passes through the cooling box 403, and the cooling box 403 is loaded with a coolant; the slide plate 404 is slidably installed in the cooling box 403 and slidably cooperates with the nitrogen output pipe 3, as shown in FIG. Figure 5 As shown, a conical scraper sleeve 411 is installed on the slide plate 404 ; and a motor 405 capable of controlling the sliding of the slide plate 404 is fixedly installed on the cooling box 403 .

[0026] The deoxygenation and purification device 1 in the utility model is a prior art. After the air is deoxygenated and purified by the deoxygenation and purification device 1, nitrogen will be output. Because heat is generated during the deoxygenation and purification process, the output nitrogen is high-temperature nitrogen and needs to be cooled. In the utility model, a cooling device 4 is designed on the nitrogen output pipe 3. When the nitrogen is output from the nitrogen output pipe 3 to the outside, it will be cooled by the coolant in the cooling box 403.

[0027] During the cooling process, impurities in the coolant will adhere to the nitrogen output pipe 3. In order to prevent this from happening, the present invention provides a slide plate 404 on the nitrogen output pipe 3, and a conical sleeve is provided on the slide plate 404. By controlling the slide plate 404 to slide, the slide plate 404 drives the conical sleeve to slide, and the conical sleeve is sleeved on the nitrogen output pipe 3. During the sliding process, the impurities on the nitrogen output pipe 3 are scraped off to prevent the impurities from affecting the cooling effect of the nitrogen.

[0028] In a further embodiment, Figure 3 , 4 As shown, a guide rod 402 is fixedly installed in the cooling box 403, and a connecting plate 412 and a transmission plate 409 are fixedly installed on the slide plate 404. The transmission plate 409 and the connecting plate 412 are slidably matched with the guide rod 402. The guide rod 402 is used to guide the slide plate 404.

[0029] In a further embodiment, Figure 3 , 4 As shown, a screw 401 is fixedly mounted on the output shaft of the motor 405, a threaded sleeve 408 is fixedly mounted on the transmission plate 409, and the screw 401 and the threaded sleeve 408 are threadedly connected. The motor 405 drives the screw 401 to rotate when it is working, because the slide plate 404 is restricted from circumferential rotation by the guide rod 402, and the slide plate 404 and the screw 401 are connected by the threaded sleeve 408, so when the screw 401 rotates, the slide plate 404 will slide relative to the screw 401 under the action of the thread, and the sliding of the slide plate 404 drives the conical scraper sleeve 411 to slide.

[0030] In a further embodiment, Figure 4 As shown, two sections of coolant pipes 407 are fixedly installed on both sides of the cooling box 403 , the lower ends of the coolant pipes 407 are located on the bottom sides of the cooling box 403 , and the upper ends of the coolant pipes 407 are located on the upper side of the cooling box 403 .

[0031] When the slide plate 404 slides, it will push the coolant in the cooling box 403 to flow. The coolant at the lower end of the coolant pipe 407 has power, and the coolant will flow from bottom to top along the coolant pipe 407, so that the coolant in the cooling box 403 flows, increasing the cooling effect of the nitrogen.

[0032] In a further embodiment, Figure 4 As shown, two heat exchangers 406 are installed on both sides of the cooling box 403, and two sections of cooling liquid pipes 407 are connected to the two heat exchangers 406. The cooling liquid flowing through the cooling liquid pipes 407 is cooled to increase the cooling effect of the nitrogen.

[0033] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be subject to the attached claims.
