[0002] With rising environmental awareness and growing demand for industrial applications, activated carbon, as a highly efficient adsorption material, plays an irreplaceable role in numerous fields, including air purification, water treatment, and solvent recovery. Ultra-high-strength activated carbon, in particular, is increasingly used under extreme conditions due to its exceptional physical and chemical properties and mechanical strength. However, to ensure the reliability and stability of this type of activated carbon in practical use, higher performance testing requirements are being placed on it.

This is particularly true when simulating real-world working environments, where factors such as temperature and pressure fluctuations are poorly controlled, leading to significant discrepancies between test results and actual conditions. Furthermore, the design of traditional clamping devices often struggles to secure high-strength activated carbon samples, making them prone to slippage or damage, impacting the accuracy and repeatability of test data.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0032] See also Figure 1-7 As shown, an embodiment of the present invention provides an experimental device for testing the properties of ultra-high-strength activated carbon, comprising an experimental chamber 1, within which is disposed a clamping mechanism for clamping an activated carbon sample. The clamping mechanism comprises an upper clamping platform 2 and a lower clamping platform 3. The upper clamping platform 2 is mounted to the top wall of the experimental chamber 1 via an upper support rod 4. Mounting methods include, but are not limited to, threaded connections, plug-in connections, and snap-on connections.

[0033] The lower clamping platform 3 is installed on the bottom plate of the experimental chamber 1 through the lower lifting rod 5. When the lower lifting rod 5 performs the lifting action, it drives the lower clamping platform 3 to approach or move away from the upper clamping platform 2 to clamp the activated carbon sample.

[0034] Activated carbon samples have different shapes due to different properties, such as spherical, cylindrical, irregular, etc., and there are also various structures such as solid, porous, and single-hole. Therefore, in order to adapt to different activated carbon samples, the clamping mechanism in the present invention also includes two auxiliary fixings 6, and the material of the auxiliary fixings 6 is stainless steel. The price of stainless steel is relatively low and the performance is stable, which is enough to adapt to the changing experimental environment. The working surfaces of the upper clamping platform 2 and the lower clamping platform 3 are both provided with mounting holes 7, and the fixed ends of the auxiliary fixings 6 are installed in the mounting holes 7. The active ends of the two auxiliary fixings 6 clamp and fix the activated carbon sample; the stainless steel material of the auxiliary fixings not only has good corrosion resistance, but also can maintain stable performance in harsh environments such as high temperature and high pressure. In addition, the auxiliary fixings made of stainless steel are easy to clean and disinfect, ensuring the accuracy and repeatability of the experiment.

[0035] like Figure 4-7 As shown, the active end of the auxiliary fixing member 6 is claw-shaped, needle-shaped, bowl-shaped, or flat. The claw shape is more suitable for clamping activated carbon with an indeterminate shape, the needle shape is suitable for clamping activated carbon with a fixed shape or a porous surface structure, the bowl shape is suitable for clamping activated carbon with a spherical shape, and the flat shape is more universal and has a wider range of applications. In the experiment, the more suitable auxiliary fixing member was selected based on factors such as the shape of the activated carbon sample. In the present invention, whether it is claw-shaped, needle-shaped, bowl-shaped, or flat, compared with the existing platform structure, that is, the method of placing the activated carbon sample stably on a flat structure, the clamping has the advantage of being more stable, and can enable the activated carbon sample to be adsorbed in multiple directions such as up, down, left, and right during testing, rather than the existing platform structure, where only the upper surface of the activated carbon sample can be tested, while the lower surface is blocked by the platform, resulting in inaccurate testing of the activated carbon sample. Preferably, when the active end of the auxiliary fixing member is claw-shaped, it includes three equal-length claws, and the angle between two adjacent claws is 120°. Auxiliary fixtures of varying shapes can better accommodate activated carbon samples of varying shapes and structures, improving clamping stability and reliability. Furthermore, claw-shaped, needle-shaped, and other auxiliary fixtures can also increase the contact area between the activated carbon sample and the test environment compared to existing technologies, improving test accuracy and sensitivity.

[0036] like Figure 3As shown, in order to determine when the auxiliary fixing part 6 is installed and to fix the auxiliary fixing part 6, a limiting groove 11 is provided in the auxiliary fixing part 6; a first groove 8 is provided on the inner wall of the mounting hole 7, and a spring part 9 and a limiting ball 10 are arranged in the first groove 8; one end of the spring part 9 is connected to the bottom of the first groove 8, and the other end is connected to the limiting ball 10. The diameter of the limiting ball 10 is smaller than the diameter of the notch of the first groove 8, so that the limiting ball 10 is pressed against the notch of the first groove 8 under the elastic force of the spring part 9. The notch is circular, and the limiting ball 10 partially protrudes from the notch of the first groove 8. The spring part 9 can be an existing pressure spring, which can provide pressure to the limiting ball 10 and push the limiting ball 10 so that it is located at the notch. The limiting ball 10 can be made of plastic or metal, which is not specifically limited here.

[0037] When the auxiliary fixing member 6 is inserted into the mounting hole 7, the fixed end of the auxiliary fixing member 6 pushes the limiting ball 10, causing the limiting ball 10 to move into the groove, thereby compressing the spring member 9. When the limiting position is reached, the portion of the limiting ball 10 protruding from the notch of the first groove 8 enters the limiting groove 11. At this time, the operator can feel through the hand that the auxiliary fixing member 6 has been installed in place, and the limiting of the auxiliary fixing member 6 is completed.

[0038] In order to confirm that the activated carbon sample has been clamped in place, a contact groove 12 is opened on the auxiliary fixing member 6, and the limiting groove 11 is located between the contact groove 12 and the fixed end of the auxiliary fixing member 6, so that when the auxiliary fixing member 6 is inserted, it first passes through the limiting groove 11 and then passes through the contact groove 12.

[0039] The inner wall of the mounting hole 7 is provided with a protruding contact 13. When the auxiliary fixing member 6 is inserted into the mounting hole 7, it will first pass through the limiting groove 11 to complete the installation of the auxiliary fixing member 6, and then the activated carbon sample is placed on the active end of the auxiliary fixing member on the lower clamping platform 3. The lower lifting rod 5 rises, driving the lower clamping platform 3 to rise, and then the two auxiliary fixing members 6 approach each other until the active ends of both auxiliary fixing members 6 contact the activated carbon sample. At this time, the lower lifting rod 5 continues to rise. Under the mutual pressure of the two auxiliary fixing members 6, the two auxiliary fixing members 6 continue to extend into their respective mounting holes 7 until they reach the contact position. The protruding contact 13 enters the contact groove 12 and touches the contact piece in the contact groove 12. The contact 13 receives the contact in place signal, and the lower lifting rod stops lifting, thereby completing the clamping of the activated carbon sample. The cooperation between the protruding contact 13 and the contact groove 12 can realize automatic clamping confirmation, improving the efficiency and accuracy of the operation. At the same time, the precise control of the lower lifting rod 5 can ensure that the activated carbon sample will not be excessively squeezed during the clamping process, thereby protecting the sample from damage.

[0040] In the present invention, the protruding contact 13 and the contact piece in the contact slot 12 generate an in-position signal by contact, which can be implemented by common knowledge. The contact signal can be an electrical connection signal, such as the protruding contact has two disconnected wire nodes, and the contact piece in the contact slot is a conductor. When the protruding contact touches the contact piece in the contact slot, the two disconnected wire nodes are connected by the contact piece, forming a path, thereby generating an electrical signal, which the controller uses as an in-position signal. Similarly, various other existing forms can be used to achieve the generation of a signal as an in-position signal by the contact of the contacts and the contact pieces, thereby confirming that the auxiliary fixing member has completed the clamping of the activated carbon sample.

[0041] Furthermore, the protruding contact 13 can be inserted into the contact slot 12 as the auxiliary fixing member 6 is inserted, and the manner in which the protruding contact 13 can be implemented in a variety of existing technologies. For example, the structure of the protruding contact 13 can be implemented by using a stop ball 10, and the extension and retraction of the protruding contact 13 can be achieved by a spring member, thereby completing the entry into the contact slot 12. Figure 3 As shown. Alternatively, the protruding contact 13 can be selected to be a metal spring sheet. When the auxiliary fixing member 6 is inserted into the mounting hole 7, the metal spring sheet is squeezed against the hole wall of the mounting hole 7. When the metal spring sheet is located at the contact slot 12, because the contact slot 12 has space, the metal spring sheet returns to its original shape and moves away from the hole wall of the mounting hole 7, thereby achieving contact with the contact slot 12. There are other implementation methods in the prior art, which are not specifically limited here. Those skilled in the art can also implement the method disclosed in the present invention. Furthermore, when the protruding contact 13 enters the contact slot 12, the limiting ball 10 disengages from the limiting slot 11. Under the action of the spring member 9, the limiting ball 10 will squeeze the auxiliary fixing member 6, making the auxiliary fixing member more stable in the mounting hole 7.

[0042] It also includes a controller 14, a drive device 15, a temperature acquisition module 16 and a heating module 17; the temperature acquisition module 16 is arranged on the wall of the experimental chamber 1, and is used to collect temperature data in the experimental chamber. The heating module 17 is arranged in the lower clamping platform 3, and is used to heat the lower clamping platform 3. The temperature in the experimental chamber 1 is increased by heating the lower clamping platform 3, and the heat can also be transferred to the auxiliary fixing part located thereon through the lower clamping platform 3, and then the auxiliary fixing part transfers the heat to the activated carbon sample to heat the activated carbon sample. The temperature acquisition module 16 can monitor the temperature changes in the experimental chamber in real time to ensure that the experiment is carried out within the appropriate temperature range. The setting of the heating module 17 can achieve precise heating of the activated carbon sample, improving the accuracy and repeatability of the test.

[0043] The output end of the controller 14 is connected to the drive device 15 and the heating module 17, respectively, for controlling the heating module 17 to heat and control the drive device 15 to perform actions. The input end is connected to the temperature acquisition module 16 for obtaining temperature data collected by the temperature acquisition module 16. The precise control of the controller 14 enables automated management of the experimental process, improving the efficiency and accuracy of the experiment. At the same time, the controller 14 can adjust the output power of the heating module in real time based on the data from the temperature acquisition module 16, ensuring that the experiment is carried out under stable temperature conditions.

[0044] The driving end of the drive device 15 is connected to the lower lifting rod 5; when the controller 14 obtains the lifting signal, the controller 14 controls the drive device 15 to drive the lower lifting rod 5 to move up and down. In the present invention, the lower lifting rod 5 needs to complete the lifting action and is driven by the drive device 15. The drive device 15 and the lower lifting rod 5 can both be implemented using existing technologies. The present invention does not make any specific redundant descriptions or limitations on the drive device 15 and the lower lifting rod 5. For example, the lower lifting rod 5 can optionally use a screw rod structure, and the drive device 15 can optionally use a motor. The motor drives the screw rod to rotate, thereby moving the nut a specific distance. The nut is fixedly connected to the lower clamping platform. In other embodiments, those skilled in the art can of course also choose other existing structures that can achieve the lifting purpose as the structure of the lower lifting rod, and the drive device can of course also be selected as other power devices such as a motor and a hydraulic motor.

[0045] In an optional embodiment, the experimental chamber 1 includes a chamber door 18; the chamber door 18 is equipped with a display device 19, and the display device 19 is connected to the output end of the controller 14, and is used to display various parameters and status information during the experiment, such as temperature, time, etc. in real time. The chamber door 18 of the experimental chamber 1 is provided with an observation window 20, and the observation window 20 is located above the display device 19, which is convenient for the experimenter to observe the internal situation of the experimental chamber 1 without interfering with the experimental process. The display device 19 can display various parameters and status information during the experiment in real time, which is convenient for the experimenter to understand the progress of the experiment at any time. The setting of the observation window allows the experimenter to observe the internal situation of the experimental chamber without opening the chamber door, avoiding interference with the experimental environment due to frequent opening of the chamber door, and improving the accuracy and repeatability of the experiment.

[0046] The following advantages are achieved by the structure of the present invention:

[0047] Improved test accuracy: The various shapes of the auxiliary fixings in the clamping mechanism can accommodate activated carbon samples of varying shapes and structures, ensuring that the sample is stably clamped during testing and preventing sample position shifts due to loose clamping that could affect test results. This significantly improves test accuracy. Compared to existing platform-based structures, the clamping method of this invention allows the activated carbon sample to be adsorbed in multiple directions, from top to bottom, left to right, during testing. This avoids the inaccurate testing caused by obstruction of the lower surface of the sample in existing structures. Comprehensive adsorption detection further enhances the accuracy of test results.

[0048] Ensure installation accuracy and operational convenience: The limiting groove on the auxiliary fixing cooperates with the spring member and limiting ball in the mounting hole to accurately determine the installation position of the auxiliary fixing, ensuring that it is installed in place and avoiding the impact of improper installation on the experimental results. At the same time, the operator can use their hands to feel the position of the limiting ball to determine whether the installation is in place, which is simple and convenient to operate. The contact groove on the auxiliary fixing cooperates with the protruding contact on the inner wall of the mounting hole to accurately confirm whether the activated carbon sample is clamped in place. When the protruding contact enters the contact groove and touches the contact piece, the contact receives the in-place signal, and the lower lifting rod stops lifting, realizing automatic clamping confirmation and improving the efficiency and accuracy of the operation.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that not every embodiment contains only one independent technical solution. In the absence of a conflict of solutions, the various technical features mentioned in each embodiment can be combined in any manner to form other implementation methods that can be understood by those skilled in the art.

[0050] In addition, without departing from the scope of the present invention, the technical solutions described in the aforementioned embodiments may be modified, or some of the technical features thereof may be replaced by equivalents, without causing the essence of the corresponding technical solutions to depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
