Description

Technical Field

[0001] The present application relates to the technical field of nitrogen production equipment, and more specifically, to a tube bundle type pressure swing adsorption nitrogen production equipment. Background Art

[0002] Nitrogen production equipment refers to equipment that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. According to different classification methods, namely cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation, industrial nitrogen generators can be divided into three types. In the research and development process of nitrogen production equipment, Shanghai Lingquan Industrial Development Co., Ltd. adopts advanced mold technology, and its performance is very stable.

[0003] According to the search, the Chinese patent with the announcement number CN217287819U discloses a tube bundle type pressure swing adsorption nitrogen production equipment, which includes a gas storage tank, a connecting pipe is provided on one side of the gas storage tank, and an adsorption tower is connected to one side of the filter bin through the connecting pipe. The top of the filter bin is provided with a connecting mechanism; the inner side of the connecting pipe is provided with a shielding mechanism. The utility model provides a connecting mechanism. When installing the filter bin, the rectangular clamping block can be rotated ninety degrees first so that the rectangular clamping block and the clamping slot are in a parallel state. Then, the rectangular clamping block can be moved to the top of the connecting plate through the clamping slot. Then, the rectangular clamping block can be released. At this time, the torsion spring is restored, thereby restoring the rectangular clamping block so that the rectangular clamping block and the clamping slot are placed at ninety degrees, thereby realizing the pre-connection between the filter bin and the connecting pipe, thereby supporting the filter bin. At this time, there is no need for staff to support the filter bin, which provides convenience for the subsequent installation and fixation of the filter bin.

[0004] Regarding the above-mentioned related technologies, the applicant believes that the telescopic spring is set between the baffle and the breathable plate, which results in external impurities not being able to enter the gas storage tank, but being able to enter the gap between the baffle and the breathable plate. As a result, when the baffle is opened, the impurities in the gap will still enter the gas storage tank. For this reason, we propose a tube bundle pressure swing adsorption nitrogen production equipment. Utility Model Content

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] See also Figure 1-4A tube bundle pressure swing adsorption nitrogen production equipment includes a main module 100 and a connection module 200. The main module 100 includes a base plate 110.

The connection module 200 includes two connection components 210 respectively arranged on the two gas storage tanks 120. Both connection components 210 are provided with a blocking component 220. A height adjustment component 240 is provided on the top of the base plate 110, and a filter bin component 230 is provided on the height adjustment component 240.

[0038] By setting the connecting component 210, the gas storage tank 120 and the blocking component 220 can be connected. By setting the blocking component 220, the air can be blocked when the connecting component 210 is separated from the filter bin component 230. At the same time, no gaps will appear during blocking, which can prevent impurities from entering through the gaps.

[0039] The connecting assembly 210 includes a connecting pipe 211 fixedly connected to the gas storage tank 120, one end of the connecting pipe 211 is fixedly connected to a blocking head 212, the inner wall of the blocking head 212 is fixedly connected to a round block 213, and the interior of the round block 213 is provided with a plurality of air-permeable grooves 214, and the blocking assembly 220 includes a bracket 221 fixedly connected to the inner cavity of the blocking head 212, a ring 222 is fixedly connected to the bracket 221, the bottom of the ring 222 is fixedly connected to a spring 223, and the bottom of the spring 223 is fixedly connected to a blocking block 224. Component 220 also includes a limiting rod 225 fixedly connected to the top of the blocking block 224, and the limiting rod 225 passes through the ring 222 and extends to the top of the ring 222. The bottom of the blocking block 224 is fixedly connected with a plurality of blocking pins 226, and the plurality of blocking pins 226 are respectively adapted to the plurality of breathable grooves 214. The blocking assembly 220 also includes an extension rod 227 fixedly connected to the bottom of the blocking block 224, and the extension rod 227 extends to the outside of the blocking head 212, and the bottom of the extension rod 227 is fixedly connected with a first breathable resistance block 228.

[0040] By pushing the first breathable resistance block 228 upward, the first breathable resistance block 228 can be driven to move upward, thereby driving the extension rod 227 to push the blocking block 224 upward, and the blocking block 224 will drive the blocking pin 226 to withdraw from the breathable groove 214, and the blocking block 224 will enter the inner cavity of the blocking head 212, so that the spring 223 can contract, thereby releasing the blockage of the blocking head 212.

[0041] The filter bin assembly 230 includes a filter bin body 231, and two air inlet pipes 232 are provided on the top of the filter bin body 231. The tops of the two air inlet pipes 232 are fixedly connected to a second breathable resistance block 233.

[0043] The implementation principle of the embodiment of the present application is: when the filter bin body 231 needs to be disassembled, the connection between the blocking head 212 and the air inlet pipe 232 is first released, and then the hydraulic cylinder 242 is started to drive the placement frame 243 to descend, thereby driving the filter bin body 231 to descend, and then the blocking head 212 and the air inlet pipe 232 can be separated, so that the first air permeable interference block 228 and the second air permeable interference block 233 can be separated, and then the interference with the first air permeable interference block 228 can be released, so that the spring 223 can be extended, thereby driving the blocking block 224 to descend and drive the blocking pin 226 to insert into the interior of the air permeable groove 214, and then the air permeable groove 214 can be blocked, thereby preventing external impurities from entering. Since the spring 223 is arranged above the blocking block 224, there will be no gap, which can prevent impurities from entering through the gap.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
