Description

Technical Field

[0001] This utility model relates to a nitrogen generator for analysis and detection, and belongs to the technical field of nitrogen generators. Background Technology

[0002] A nitrogen generator is a device used to produce high-purity nitrogen gas. It is commonly used in laboratories, hospitals, pharmaceutical factories, and other similar locations. In nitrogen generator production, air is typically pumped into the generator, where it is separated into high-purity nitrogen gas at room temperature using the pressure swing adsorption principle. However, existing laboratory nitrogen generators require the intake air to be filtered through a filter screen. These filters lack automatic cleaning capabilities, and over time, dust and impurities accumulate, clogging the screen and affecting the air intake speed, thus impacting the efficiency of nitrogen production in laboratory settings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a nitrogen generator for analysis and detection. It solves the problem that in the existing nitrogen generator, the air drawn in needs to be filtered through a filter screen, but the filter screen does not have an automatic cleaning function. Over time, dust and impurities in the air easily clog the filter screen, which affects the air intake speed and the efficiency of nitrogen production in the laboratory nitrogen generator.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: A nitrogen generator for analysis and detection, wherein the nitrogen generator is provided with an air inlet pipe, and a filter box is provided on the air inlet pipe. The filter box has a cavity structure, and a filter plate is provided inside the cavity structure. An installation plate is fixedly provided on the filter box. A sliding groove is opened on the installation plate, and a sliding plate is slidably provided inside the sliding groove. A push plate is horizontally fixedly provided at one end of the sliding plate, and one end of the push plate extends to the outside of the installation plate. A spring is fixedly provided between the push plate and the filter box. The end of the sliding plate away from the push plate extends into the cavity structure and is fixedly provided with a cleaning plate. A brush is fixedly provided on the cleaning plate, and the brush abuts against the filter plate.

[0005] By adopting the above technical solution, when the nitrogen generator is working, air enters the inlet pipe and passes through the filter plate to filter dust and impurities in the air, preventing impurities from affecting product quality and the stability of the production process. When the nitrogen generator is finished and the filter plate needs to be cleaned, pressing the push plate moves the sliding plate in the sliding groove. During the movement, the sliding plate compresses the spring through the push plate, and at the same time, the sliding plate also moves the cleaning plate in the cavity structure. Then, the cleaning plate drives the brush to clean the filter plate. At this time, releasing the push plate causes the spring to reset and push the sliding plate and push plate to move back to their original positions. Then, the sliding plate drives the cleaning plate and brush to move back to their original positions, realizing the reciprocating cleaning of the filter plate. The brush can remove dirt from the surface of the filter plate, maintain the filtration performance of the filter plate, and ensure the quality of the air entering the nitrogen generator. Regular cleaning of the filter plate can effectively prevent filter plate blockage, ensure stable airflow in the inlet pipe, thereby reducing equipment failure and improving the operational stability of the equipment.

[0006] The present invention is further configured such that: a sliding channel communicating with the cavity structure is provided on the filter box, a collection box is provided inside the cavity structure, the collection box can slide to the outside of the filter box through the sliding channel, and a guide plate is fixedly provided inside the cavity structure, the guide plate being located between the filter plate and the collection box.

[0007] By adopting the above technical solution and through the above working process, the dust on the filter plate is cleaned. The cleaned dust passes through the guide plate and then falls into the inside of the collection box, which facilitates the centralized collection and treatment of the dust.

[0008] The present invention is further configured as follows: a guide groove is provided on the filter box, a guide block is slidably disposed inside the guide groove, a positioning block is fixedly disposed on the guide block, a positioning groove is provided on the filter plate, and a driving structure is provided on the filter box. The driving structure is used to insert and separate the positioning block and the positioning groove. The driving structure includes a threaded rod that is threadedly connected to the filter box, one end of the threaded rod extending into the interior of the guide groove and rotatably connected to the guide block, and a rotating block fixedly disposed on the other end of the threaded rod.

[0009] By adopting the above technical solution, the rotating block drives the threaded rod to rotate, and then the threaded rod drives the guide block to slide in the guide groove. Then the guide block drives the positioning block to move away from the positioning groove, which can realize the limiting and separation of the filter plate. By removing the limiting of the filter plate, the limiting plate can be moved to the outside of the filter box, which facilitates the subsequent maintenance and replacement of the filter plate.

[0010] The present invention is further configured such that: a handle is fixedly installed on the filter plate, and a sealing layer is provided on the filter plate.

[0011] By adopting the above technical solution, the sealing layer can prevent gaps between the filter plate and the cavity structure, ensuring that all air entering the filter box is filtered through the filter plate, thus guaranteeing the integrity of the filtration process.

[0012] The present invention is further configured such that: a dust cover is provided on the filter box, the air inlet end of the air inlet pipe is located inside the dust cover, and the dust cover and the filter box are detachably and fixedly connected.

[0013] By adopting the above technical solution, the air intake pipe is sealed and protected by a dust cover when the device is not in use; the dust cover can be easily removed through a detachable connection.

[0014] The beneficial effects of this invention are as follows: When the nitrogen generator is working, air enters the inlet pipe and passes through the filter plate to filter dust and impurities in the air, preventing impurities from affecting product quality and the stability of the production process. When the nitrogen generator is finished and the filter plate needs to be cleaned, pressing the push plate causes the sliding plate to slide in the sliding groove. During the movement of the sliding plate, the spring is compressed, and the sliding plate also causes the cleaning plate to slide in the cavity structure. Then, the cleaning plate drives the brush to clean the filter plate. At this time, releasing the push plate causes the spring to reset and push the sliding plate to move back to its original position. Then, the sliding plate drives the cleaning plate and the brush to move back to its original position, realizing the reciprocating cleaning of the filter plate. The brush can remove dirt from the surface of the filter plate, maintain the filtration performance of the filter plate, and ensure the quality of the air entering the nitrogen generator. Regularly cleaning the filter plate can effectively prevent filter plate blockage, ensure stable airflow in the inlet pipe, thereby reducing equipment failure and improving the operational stability of the equipment.

[0021] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] like Figures 1 to 4 As shown, a nitrogen generator for analysis and detection includes a nitrogen generator 1 with an inlet pipe 2 and a filter box 3 mounted on the inlet pipe 2. The filter box 3 is a hollow structure 4. The inlet pipe 2 is divided into two sections, and the filter box 3 is located between the two sections of the inlet pipe 2. The inlet pipe 2 and the hollow structure 4 are connected. A filter plate 5 is installed inside the hollow structure 4, and an installation groove is formed on the inner wall of the hollow structure 4. Both sides of the filter plate 5 extend into the installation groove. An installation plate 6 is fixedly mounted on the filter box 3, and a sliding groove 7 is formed on the installation plate 6. The sliding groove 7 is radially formed, and a sliding plate 8 is slidably mounted inside the sliding groove 7. One end of the sliding plate 8 is horizontally fixed. A push plate 10 is provided, with one end of the push plate 10 extending to the outside of the mounting plate 6. The end of the sliding plate 8 away from the push plate 10 extends into the cavity structure 4 and is fixedly provided with a cleaning plate 11. A brush 12 is fixedly provided on the cleaning plate 11. The brush 12 abuts against the filter plate 5 and slides back and forth along the filter plate 5 to clean the filter plate 5. A spring 9 is fixedly provided between the push plate 10 and the filter box 3. The elastic force of the spring 9 is in the same direction as the sliding direction of the push plate 10. The spring 9 is in a tensioned state when working. By compressing and resetting the spring 9, the cleaning plate 11 can be driven to reciprocate to clean the filter plate 5.

[0023] like Figure 3 As shown, the filter box 3 has a sliding channel 1011 that communicates with the cavity structure 4. A collection box 1012 is provided inside the cavity structure 4. The collection box 1012 can slide to the outside of the filter box 3 through the sliding channel 1011. A guide plate 1013 is located between the filter plate 5 and the collection box 1012. The guide plate 1013 is located below the filter plate 5, and the collection box 1012 is located below the guide plate 1013.

[0024] like Figure 5As shown, the filter box 3 has a guide groove 1021, and a guide block 1022 is slidably disposed inside the guide groove 1021. The guide block 1022 reciprocates along the opening direction of the guide groove 1021. A positioning block 1023 is fixedly disposed on the guide block 1022. A positioning groove 1024 is disposed on the filter plate 5. The positioning block 1023 and the positioning groove 1024 are inserted into each other. The filter box 3 is provided with a driving structure. The driving structure includes a threaded rod 1031 that is threadedly connected to the filter box 3. One end of the threaded rod 1031 extends into the interior of the guide groove 1021 and is rotatably connected to the guide block 1022. The positioning block 1023 is fixedly disposed on the side of the guide block 1022 away from the threaded rod 1031. A rotating block 1032 is fixedly disposed on the other end of the threaded rod 1031, which allows the threaded rod 1031 to be rotated easily.

[0025] like Figure 2 and Figure 3 As shown, a handle 1041 is fixedly installed on the filter plate 5. The filter plate 5 can be moved by the handle 1041 to facilitate installation and disassembly. A sealing layer 1042 is provided on the filter plate 5.

[0026] like Figure 1 As shown, a dust cover 1051 is provided on the filter box 3, and the air inlet end of the air inlet pipe 2 is located inside the dust cover 1051. The dust cover 1051 and the filter box 3 are detachably fixedly connected. The detachable connection includes, but is not limited to, snap-fit, which is achieved by snap-fitting the clips on the dust cover 1051 and the slots on the filter box 3.

[0027] When the nitrogen generator 1 is working, air enters through the inlet pipe 2 and passes through the filter plate 5 to filter dust and impurities in the air, preventing impurities from affecting product quality and the stability of the production process. When the nitrogen generator 1 is finished and the filter plate 5 needs to be cleaned, the push plate 10 is pressed to drive the sliding plate 8 to slide in the sliding groove 7. During the movement, the sliding plate 8 compresses the spring 9 through the push plate 10, and at the same time, the sliding plate 8 also drives the cleaning plate 11 to slide in the cavity structure 4. Then, the cleaning plate 11 drives the brush 12 to clean the filter plate 5. During cleaning, the push plate 10 is released, and the spring 9 resets the sliding plate 8 and the push plate 10, causing them to move back to their original positions. Then, the sliding plate 8 drives the cleaning plate 11 and the brush 12 to move back to their original positions, thus achieving reciprocating cleaning of the filter plate 5. The brush 12 can remove dirt from the surface of the filter plate 5, maintain the filtration performance of the filter plate 5, and ensure the quality of the air entering the nitrogen generator 1. Regularly cleaning the filter plate 5 can effectively prevent clogging of the filter plate 5, ensure stable airflow in the air inlet pipe 2, thereby reducing equipment failures and improving the operational stability of the equipment.

[0028] The dust on the filter plate 5 is cleaned through the above working process. The cleaned dust passes through the guide plate 1013 and then falls into the collection box 1012, which facilitates the centralized collection and treatment of the dust.

[0029] The rotating block 1032 drives the threaded rod 1031 to rotate, and then the threaded rod 1031 drives the guide block 1022 to slide in the guide groove 1021. Then the guide block 1022 drives the positioning block 1023 to move away from the positioning groove 1024, thereby realizing the limiting and separation of the filter plate 5. By removing the limiting of the filter plate 5, the filter plate 5 can be moved to the outside of the filter box 3, which facilitates the subsequent maintenance and replacement of the filter plate 5.

[0030] The sealing layer 1042 prevents gaps between the filter plate 5 and the mounting groove, ensuring that all air entering the filter box 3 is filtered through the filter plate 5, thus guaranteeing the integrity of the filtration process.

[0031] When the device is not in use, the air inlet pipe 2 is sealed and protected by the dust cover 1051; the dust cover 1051 can be easily removed by means of a detachable connection.
