Description

Technical Field

[0001] This utility model relates to the field of nitrogen generation equipment, specifically to a nitrogen generation device with a drawer-type quick-change filter element. Background Technology

[0002] Nitrogen generators, as the core equipment for producing high-purity nitrogen, are widely used in various industrial and civilian fields such as chemical industry, food preservation, electronic packaging, and pharmaceutical storage. During operation, they need to filter and purify the raw gas by removing impurities such as moisture, oil, and dust to ensure that the purity of the produced nitrogen meets the standards.

[0003] Under the current technological system, nitrogen generator filter cartridges are mostly installed using a traditional built-in fixing structure. The filter cartridges are usually directly nested or fixed to a special bracket inside the equipment with bolts, and there is a lack of matching pull-out guide components. When replacing the filter cartridge, workers must first remove multiple components such as the protective cover and connecting pipes on the outside of the equipment before they can access the filter cartridge. During the fixing and disassembly of the filter cartridge, tools such as wrenches are often needed to operate the fasteners one by one. This not only makes the disassembly and assembly process cumbersome, but also makes filter cartridge replacement difficult and time-consuming, increasing the risk of production interruption, and also increases the workload of workers. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings and provide a nitrogen generator with a drawer-type quick-change filter element. This reduces the maintenance time, improves the convenience and practicality of using the nitrogen generator, and solves the technical problems of existing technologies where filter element replacement is difficult, time-consuming, increases the risk of production interruption, and increases the workload of workers.

[0005] The objective of this utility model is achieved through the following means:

[0006] A nitrogen generator with a drawer-type quick-change filter cartridge includes a nitrogen generator housing. A processing device is mounted on the surface of the housing. An installation groove is formed inside the housing, and a drawer is inserted into the inner cavity of the installation groove. Guide blocks are mounted on the surface of the drawer, and guide rails are mounted on the inner wall of the installation groove. Mounting seats are evenly distributed within the inner cavity of the drawer. Each mounting seat has a clamp on its upper surface, a rotating shaft is mounted at the connection of each clamp, and an installation cylinder is mounted at the connection of each mounting seat. The rotating shaft is inserted into the interior of each installation cylinder. Positioning blocks are mounted on the surface of each clamp, and positioning seats are mounted on the surface of each mounting seat at positions corresponding to the positioning blocks. Sealing seats are mounted on the inner wall of the drawer at positions corresponding to the mounting seats, and sealing rings are mounted on the surface of each sealing seat.

[0007] Furthermore, the surface of the sealing seat is provided with a groove, and the sealing ring is installed in the groove of the sealing seat. A spring is installed between the sealing ring and the sealing seat. The spring can ensure that the sealing ring and the sealing seat always maintain a tight fit to prevent gas leakage.

[0008] Furthermore, the inner wall of the sealing ring is evenly provided with limiting blocks, and the groove of the sealing seat is provided with limiting grooves at the corresponding positions of the limiting blocks. The limiting blocks are installed inside the limiting grooves, so that the sealing ring is not easy to tilt.

[0009] Furthermore, the surface of the guide block is equipped with a blocking block, and the inner cavity of the guide rail is equipped with a retaining edge to ensure the stable operation of the drawer within the guide rail and to prevent derailment.

[0010] Furthermore, each of the positioning blocks is equipped with a connector at its bottom. The connector is designed to be flexible, and each of the positioning bases has a slot for insertion. The flexible design of the connector allows it to deform to a certain extent when inserted into the slot, which can better adapt to the shape of the slot, increase the contact area between the two, improve the accuracy and stability of positioning, and also play a certain buffering role to reduce the impact force on the component during insertion.

[0011] Furthermore, the surface of the connector is evenly distributed with anti-slip protrusions, and the inner wall of the connector groove is provided with grooves at positions corresponding to the anti-slip protrusions. When the connector is inserted into the connector groove, the anti-slip protrusions are embedded in the grooves, forming a snap-fit ​​connection structure, which further enhances the connection between the positioning block and the positioning seat and prevents loosening or falling off during use.

[0012] The beneficial effects of this utility model are as follows: the guide block and guide rail work together to guide the drawer to be pulled out stably in the mounting slot, making it easy for workers to quickly remove or push the drawer out of the mounting slot. The clamp is rotatably connected to the mounting cylinder at the connection of the mounting base through the rotating shaft, so that the clamp can be opened and closed around the rotating shaft. At the same time, the positioning block on the surface of the clamp and the positioning seat on the surface of the mounting base correspond to each other, which can ensure the accuracy of the clamp's position when fixing the filter element. The combination of the drawer-type design and the easy-to-operate clamp fixing structure greatly simplifies the operation steps of filter element replacement, reduces the difficulty of equipment maintenance, reduces the maintenance time required, and improves the convenience and practicality of nitrogen generators during use.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] In this embodiment, refer to Figures 1-7 The specific implementation of a nitrogen generator with a drawer-type quick-change filter element includes a nitrogen generator housing 1, and a processing device 101 is installed on the surface of the nitrogen generator housing 1.

[0023] The processing device 101 includes an air compression and pretreatment system, a nitrogen-oxygen separation core device and a control system, which is a mature solution for existing nitrogen generation equipment and will not be described in detail here.

[0024] The nitrogen generator housing 1 has an internal mounting groove 2. A drawer 3 is inserted into the inner cavity of the mounting groove 2. A guide block 4 is installed on the surface of the drawer 3. A guide rail 5 is installed on the inner wall of the mounting groove 2. Mounting seats 6 are evenly distributed in the inner cavity of the drawer 3. Each mounting seat 6 has a clamp 7 on top. A rotating shaft 8 is installed at the connection of the clamp 7. An mounting cylinder 9 is installed at the connection of the mounting seat 6. The rotating shaft 8 is inserted into the interior of the mounting cylinder 9. A positioning block 10 is installed on the surface of the clamp 7. A positioning seat 11 is installed on the surface of the mounting seat 6 at the corresponding position of the positioning block 10. A sealing seat 12 is installed on the inner wall of the drawer 3 at the corresponding position of the mounting seat 6. A sealing ring 13 is installed on the surface of the sealing seat 12.

[0025] The mounting groove 2 inside the nitrogen generator housing 1 provides installation space for the drawer 3. The guide block 4 on the surface of the drawer 3 cooperates with the guide rail 5 on the inner wall of the mounting groove 2 to guide the drawer 3 to be stably pulled out and pushed in within the mounting groove 2, making it easy for operators to quickly remove or push the drawer 3 out of the mounting groove 2, providing a convenient operating basis for filter element replacement. The mounting seat 6 inside the drawer 3 is used to place the filter element. The clamp 7 above the mounting seat 6 is rotatably connected to the mounting cylinder 9 at the connection point of the mounting seat 6 via a rotating shaft 8, allowing the clamp 7 to open and close around the rotating shaft 8, facilitating the fixing or loosening of the filter element on the mounting seat 6. At the same time, the positioning block 10 on the surface of the clamp 7 corresponds to the positioning seat 11 on the surface of the mounting seat 6, ensuring the clamp... 7. The accuracy of the filter element's position during fixing is ensured to prevent the filter element from shifting due to unstable fixing during equipment operation, which would affect the nitrogen generation effect. The sealing seat 12 and the sealing ring 13 on the surface of the sealing seat 12, which are located on the inner wall of the drawer 3 and the mounting base 6 respectively, can enhance the sealing between the inside and outside of the drawer 3 after the drawer 3 is pushed into the mounting groove 2, reduce gas leakage during the flow of gas inside the equipment, ensure the gas production efficiency of the nitrogen generator and the purity of the produced nitrogen. Moreover, the overall structure, through the combination of drawer-type design and easy-to-operate clamp 7 fixing structure, greatly simplifies the operation steps of filter element replacement, reduces the difficulty of equipment maintenance, reduces the maintenance time required, and improves the convenience and practicality of nitrogen generator during use.

[0026] The surface of the sealing seat 12 has a groove, and the sealing ring 13 is installed in the groove of the sealing seat 12. A spring 14 is installed between the sealing ring 13 and the sealing seat 12. The spring 14 can ensure that the sealing ring 13 and the sealing seat 12 always maintain a tight fit to prevent gas leakage.

[0027] The inner wall of the sealing ring 13 is evenly provided with limiting blocks 15.

The surface of the positioning seat 11 is provided with a insertion groove 20. The flexible design of the connector 19 allows it to deform to a certain extent when inserted into the insertion groove 20, so as to better adapt to the shape of the insertion groove 20, increase the contact area between the two, improve the accuracy and stability of positioning, and also play a certain buffering role to reduce the impact force during insertion and damage to the components.

[0030] The surface of the connector 19 is evenly distributed with anti-slip protrusions 21. The inner wall of the connector groove 20 is provided with grooves corresponding to the anti-slip protrusions 21. When the connector 19 is inserted into the connector groove 20, the anti-slip protrusions 21 are embedded in the grooves, forming a snap-fit ​​connection structure, which further enhances the connection between the positioning block 10 and the positioning seat 11 and prevents loosening or falling off during use.

[0031] In this solution, the operator pulls out drawer 3. With the cooperation of guide block 4 and guide rail 5, and the action of blocking block 17 and stop edge 18, drawer 3 is stably pulled out from mounting groove 2. Clamp 7 is opened, and shaft 8 rotates in mounting cylinder 9. The old filter element is removed, a new filter element is placed in, and clamp 7 is closed. The elastic plug 19 at the bottom of positioning block 10 is inserted into the plug groove 20 of positioning seat 11. Anti-slip protrusion 21 is embedded in the groove to ensure that clamp 7 accurately fixes the filter element position. Then, drawer 3 is pushed into mounting groove 2. The sealing seat 12 has a sealing ring 13 with limit block 15 in the groove. Under the action of spring 14, it fits tightly with sealing seat 12. Limit block 15 is in the limit groove 16 to prevent tilting, enhance sealing, and ensure the gas production efficiency and nitrogen purity of nitrogen generator.
