Description

Technical Field

[0001] This utility model relates to the field of experimental instruments, and more specifically, to a portable and replaceable adsorption tower structure for experimental instruments. Background Technology

[0002] Currently, adsorption towers play a crucial role in various experiments, enabling the adsorption of specific gases to ensure the accuracy of experimental data and the reliability of experimental results. However, the replacement structure of adsorption towers in current experimental instruments has many problems, seriously affecting the efficiency and quality of experiments.

[0003] Existing adsorption tower replacement structures primarily employ threaded connections or pneumatic fittings. When using threaded connections, replacing the adsorption tower is extremely cumbersome. Operators must first unscrew the external components, then remove the internal plugs. This process is not only time-consuming and labor-intensive but also demands a high level of operator skill. During installation, careful alignment of the interfaces and ensuring the correct positioning of the sealing rings are crucial; otherwise, air leaks can easily occur. Air leaks not only lead to inaccurate experimental data but may also disrupt the normal conduct of the experiment and even threaten the experimental environment and the safety of the operators.

[0004] While pneumatic connectors improve connection convenience to some extent, specialized tools are still required for disassembly and assembly when replacing the adsorption tower. This not only increases the skill requirements of operators but also makes the process relatively complex. Furthermore, using tools for disassembly and assembly can easily damage the connectors due to improper handling, further increasing maintenance costs and the risk of experimental interruptions.

[0005] Furthermore, existing adsorption tower replacement structures lack consideration for rapid replacement in their design, failing to meet the high efficiency requirements of modern experiments. In experiments requiring frequent adsorption tower replacements, existing replacement structures slow down the experimental process and reduce efficiency. Therefore, there is an urgent need for a portable adsorption tower replacement structure that enables rapid and convenient replacement of adsorption towers while ensuring connection sealing and stability. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a portable replacement adsorption tower structure for experimental instruments, aiming to improve the problem that the existing adsorption tower replacement structure lacks consideration for rapid replacement in its design and cannot meet the requirements of modern experiments for high efficiency.

[0007] This utility model is implemented as follows: a portable replaceable adsorption tower structure for an experimental instrument, comprising an adsorption tower body, a mounting plate, and connecting components for connecting the two. The adsorption tower body includes a cylinder, which is filled with packing material. Stainless steel gaskets and degreased cotton are provided at both ends of the cylinder. Self-locking pneumatic quick-connect female connectors are respectively installed at the air outlets at both ends of the cylinder. Two self-locking pneumatic quick-connect male connectors are correspondingly installed on the mounting plate. The self-locking pneumatic quick-connect male connectors are connected to the air circuit of the experimental instrument, and the self-locking pneumatic quick-connect female connectors and the self-locking pneumatic quick-connect male connectors are mutually compatible.

[0008] In the preferred embodiment of this utility model, the cylinder is actually a cylindrical container in the adsorption tower body used to fill filler materials and other substances, allowing gas to pass through and undergo adsorption, etc. It is essentially more similar to a gas processing chamber.

[0009] In a preferred embodiment of this invention, the cylinder is fixedly connected to the self-locking pneumatic quick-connect female connector via welding or threaded connection. When welding is used, high temperature is used to melt the connection area between the cylinder end and the self-locking pneumatic quick-connect female connector, forming a strong bond after cooling and solidification. This connection method allows the two to become a single unit. During the connection process, precise control of welding parameters, such as welding current, voltage, and welding speed, is required to ensure welding quality. The selection of welding materials must consider their compatibility with the materials of the cylinder and the self-locking pneumatic quick-connect female connector to ensure connection stability. If a threaded connection is used, matching threads are machined at corresponding positions on the cylinder end and the self-locking pneumatic quick-connect female connector. During installation, the self-locking pneumatic quick-connect female connector is screwed into the cylinder end, and the threads engage to achieve fixation. When machining the threads, the accuracy and dimensions of the threads must meet standards to ensure a tight connection. Additionally, to prevent loosening of the threads during use, thread-locking adhesive or other auxiliary fixing measures can be used.

[0010] In a preferred embodiment of this invention, the mounting plate is provided with mounting holes for fixing the self-locking pneumatic quick-connect male connector. The self-locking pneumatic quick-connect male connector is installed in the mounting holes via an interference fit or a threaded connection. For the interference fit method, the dimensions of the mounting hole and the self-locking pneumatic quick-connect male connector must be precisely designed. The inner diameter of the mounting hole should be slightly smaller than the outer diameter of the self-locking pneumatic quick-connect male connector; the difference between the two dimensions is the interference amount. During installation, the mounting hole is usually heated or the self-locking pneumatic quick-connect male connector is cooled to change their dimensions, allowing for smooth assembly. Heating the mounting hole can be achieved using a heat-shrink method, where the mounting plate is heated to a certain temperature, causing the mounting hole to expand. Then, the self-locking pneumatic quick-connect male connector is quickly inserted. After the mounting plate cools, the mounting hole contracts.

[0011] If a threaded connection is used, matching threads are machined on the inner wall of the mounting hole and the outer surface of the male self-locking pneumatic quick-connect coupling. During installation, the male self-locking pneumatic quick-connect coupling is screwed into the mounting hole, and the thread tightening force is used to secure it. When machining the threads, it is necessary to ensure that the thread profile, pitch, and other parameters meet the requirements, and the thread surface should be properly treated to improve the wear resistance and corrosion resistance of the threads.

[0012] In a preferred embodiment of this invention, the mounting plate is installed on the chassis or wall of the experimental instrument by means of bolt connection or snap-fit. When bolt connection is used, a washer, such as a spring washer, can be added between the bolt and the nut to prevent the nut from loosening; if snap-fit ​​is used, a snap-fit ​​structure, such as a hook or groove, is provided on the mounting plate, and a corresponding mating structure is provided on the chassis or wall of the experimental instrument.

[0013] In a preferred embodiment of this invention, the stainless steel gasket is fixed to the end of the cylinder by adhesive bonding or welding. When using adhesive bonding, a suitable adhesive for stainless steel must be selected. Before bonding, the cylinder end and the bonding surfaces of the stainless steel gasket need to be cleaned to remove oil, dust, and other impurities to improve the adhesive's bonding strength. Then, the adhesive is evenly applied to one of the bonding surfaces, and the stainless steel gasket is aligned and bonded to the cylinder end, applying pressure to ensure the adhesive fully fills the gap between them. During the adhesive curing process, the bonding area must be kept stable to avoid interference from external forces. If welding is used, similar to welding the cylinder and the self-locking pneumatic quick-connect female connector, a suitable welding method and welding materials must be selected based on the materials of the stainless steel gasket and the cylinder. During welding, the welding heat must be controlled to avoid deformation or damage to the stainless steel gasket due to overheating. Simultaneously, the quality of the weld joint must be ensured to prevent defects such as incomplete welds and porosity.

[0014] In a preferred embodiment of this invention, the degreased cotton is filled between the stainless steel gasket and the packing material, and fits tightly against the inner wall of the cylinder. When filling the cylinder, the degreased cotton is first cut to a suitable size according to the cylinder's inner diameter and length. Then, the degreased cotton is gradually filled into the space between the stainless steel gasket and the packing material. During the filling process, it is essential to ensure that the degreased cotton is evenly distributed and fits tightly against the inner wall of the cylinder. Tools can be used to gently compact the degreased cotton, but care should be taken not to over-compress it, as this may affect the performance of the packing material and the flow of gas. Simultaneously, it is crucial to ensure that the degreased cotton does not loosen or shift, preventing it from entering the gas path and causing blockage during the experiment.

[0015] In a preferred embodiment of this invention, the male self-locking pneumatic quick-connect coupling is connected to the gas circuit of the experimental instrument via an internally threaded elbow and a one-tap threaded connector. One end of the internally threaded elbow is threadedly connected to the male self-locking pneumatic quick-connect coupling, and the other end is threadedly connected to the one-tap threaded connector, which is then connected to the gas circuit of the experimental instrument. During the connection process, first check whether the thread sizes of the internally threaded elbow, the one-tap threaded connector, and the male self-locking pneumatic quick-connect coupling are compatible. Align one end of the internally threaded elbow with the male self-locking pneumatic quick-connect coupling, and then connect them by rotation. When connecting, ensure moderate tightening force to avoid overtightening, which could damage the threads, or undertightening, which could lead to air leakage. Next, thread the other end of the internally threaded elbow to the one-tap threaded connector, again ensuring a tight connection. Finally, connect the one-tap threaded connector to the gas circuit of the experimental instrument, operating according to the specific connection method of the gas circuit, such as using sealing rings for sealing, to ensure the airtightness of the entire gas circuit connection.

[0016] In a preferred embodiment of this utility model, the mounting plate is further provided with a decorative cover plate, which is installed on the mounting plate by means of a snap fastener or bolt connection, and covers the self-locking pneumatic quick connector male and related connecting parts.

[0017] The beneficial effects of this utility model are:

[0018] Convenient and efficient replacement: This invention uses a self-locking pneumatic quick connector to connect the adsorption tower body to the mounting plate. Simply press to engage, and pull the latch to disengage. No additional tools or tedious screw-tightening are required. This significantly reduces adsorption tower replacement time and improves experimental efficiency, making it particularly suitable for experiments requiring frequent tower replacements.

[0019] Stable and reliable connection: The cylinder and the female self-locking pneumatic quick connector are fixed by welding or threaded connection, and the male self-locking pneumatic quick connector is installed on the mounting plate by interference fit or threaded connection. These connection methods ensure that the connection between the components is firm and can withstand certain vibrations and external forces during the operation of the experimental instrument without loosening, thus ensuring the stability of the adsorption tower structure.

[0020] Excellent sealing performance: The stainless steel gasket is fixed to the cylinder end by adhesive or welding. Degreased cotton is filled between the stainless steel gasket and the packing and fits tightly against the inner wall of the cylinder. At the same time, the snap-fit ​​connection of the self-locking pneumatic quick connector also has good sealing performance, which can effectively prevent gas leakage and ensure the sealing of the experimental gas circuit, thereby improving the accuracy of experimental data.

[0021] Flexible and diverse installation: The mounting plate can be installed on the chassis or wall of the experimental instrument by bolt connection or snap-fit. Users can choose the appropriate installation position and method according to the actual experimental environment and needs, which enhances the applicability and flexibility of the structure.

[0022] Structural protection and aesthetics: The decorative cover plate on the mounting plate can cover the male of the self-locking pneumatic quick connector and related connecting parts, which not only protects the internal connecting parts from contamination and damage by external dust, debris, etc., but also makes the entire adsorption tower structure more beautiful and neat.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] Please see Figures 1-5 This utility model provides a technical solution: a portable replaceable adsorption tower structure for an experimental instrument, comprising an adsorption tower body, a mounting plate 6, and connecting components for connecting the two. The adsorption tower body includes a cylinder 2, which is filled with packing material. Stainless steel gaskets and degreased cotton are provided at both ends of the cylinder 2. Self-locking pneumatic quick connector females 3 are respectively installed at the air outlets at both ends of the cylinder 2. Two self-locking pneumatic quick connector males 4 are correspondingly installed on the mounting plate 6. The self-locking pneumatic quick connector males 4 are connected to the air circuit of the experimental instrument. The self-locking pneumatic quick connector females 3 and self-locking pneumatic quick connector males 4 are mutually compatible and are locked together by pressing. Pulling the latch on the self-locking pneumatic quick connector female can separate the two. The cylinder 2 is fixedly connected to the self-locking pneumatic quick connector females 3 by welding or threaded connection. The mounting plate 6 is provided with mounting holes for fixing the self-locking pneumatic quick connector males 4. The self-locking pneumatic quick connector males 4 are installed in the mounting holes by interference fit or threaded connection.

[0032] In some specific implementation schemes, the mounting plate 6 is installed on the chassis or wall of the experimental instrument by bolt connection or snap-fit. The bolt connection method is reliable and can withstand greater external forces and vibrations, ensuring that the mounting plate 6 is stably fixed to the chassis or wall, thus guaranteeing the stability of the entire adsorption tower structure. The snap-fit ​​method has the advantages of rapid and convenient installation, requiring no tools and allowing for quick installation and removal of the mounting plate 6, improving the efficiency of experimental instrument assembly and debugging.

[0033] In some specific implementations, the stainless steel gasket is fixed to the end of cylinder 2 by adhesive bonding or welding. Adhesive bonding is simple to operate, causes minimal damage to cylinder 2 and stainless steel gasket, and can provide a certain degree of sealing and buffering, preventing gas leakage from the connection between the gasket and cylinder 2. Welding, on the other hand, firmly bonds the stainless steel gasket to cylinder 2, enhancing structural stability and sealing, and is suitable for experimental scenarios with high requirements for sealing and connection strength.

[0034] In some specific implementations, degreased cotton is filled between the stainless steel gasket and the packing material, and is tightly fitted to the inner wall of cylinder 2. This filling provides both filtration and buffering. The filtration prevents packing particles from entering the gas path, avoiding blockages and contamination, and ensuring unobstructed flow of the experimental gas. The buffering effect reduces the impact of gas flow on the packing material, protecting it from damage and extending its service life.

[0035] In some specific implementation schemes, the self-locking pneumatic quick-connect male connector 4 is connected to the gas path of the experimental instrument via an internally threaded elbow connector 1 and a one-tap connector 5. One end of the internally threaded elbow connector 1 is threaded to the self-locking pneumatic quick-connect male connector 4, and the other end is threaded to the one-tap connector 5. The one-tap connector 5 is connected to the gas path of the experimental instrument. The internally threaded elbow connector 1 can change the direction of the gas path to adapt to different experimental instrument layouts and installation space requirements. The one-tap connector 5 can be connected to the gas paths of various types of experimental instruments, improving the compatibility of the adsorption tower structure with different experimental instruments.

[0036] In some specific implementation schemes, the mounting plate 6 is also equipped with a decorative cover plate 7. The decorative cover plate 7 is installed on the mounting plate 6 by means of snap-fit ​​or bolt connection, and covers the self-locking pneumatic quick connector male 4 and related connecting parts. The snap-fit ​​connection method facilitates the quick installation and removal of the decorative cover plate 7, making it convenient for inspection and maintenance of internal connecting parts. The bolt connection method makes the installation of the decorative cover plate 7 more secure, effectively protecting the internal connecting parts from external dust and debris contamination and damage, while also making the overall adsorption tower structure more neat and aesthetically pleasing.

[0037] Working principle: In an interference fit, after the shaft and hole are assembled, because the shaft size is larger than the hole size, the shaft will exert radial pressure on the hole, causing the hole to undergo elastic deformation. At the same time, the shaft will also have a certain degree of elastic contraction. The pressure generated by this elastic deformation will create a large frictional force between the mating surfaces of the shaft and the hole, thereby firmly connecting the two parts together. It can withstand certain loads such as torque and axial force, ensuring that the parts do not move relative to each other during operation.

[0038] When the adsorption tower needs to be replaced, simply pull the latch on the female of the self-locking pneumatic quick connector 3 gently to remove the adsorption tower. Then, align the male and female connectors of the prepared new adsorption tower and press to complete the installation.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
