In addition, the design of traditional clamping devices often fails to meet the fixation requirements of high-strength activated carbon samples, and the samples are prone to slippage or damage, affecting the accuracy and repeatability of the test data.

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the 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 creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-7 As shown, an experimental device for ultra-high strength activated carbon performance testing provided by an embodiment of the present invention includes an experimental chamber 1, and a clamping mechanism for clamping an activated carbon sample is arranged in the experimental chamber 1. The clamping mechanism includes an upper clamping platform 2 and a lower clamping platform 3. The upper clamping platform 2 is mounted on the top wall of the experimental chamber 1 through an upper support rod 4, and the mounting method includes but is not limited to existing connection methods such as threaded connection, plug-in connection, and clamping connection.

[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 a 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 various shapes due to different properties, such as spherical, cylindrical, irregular shapes, 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 two active ends of the auxiliary fixings 6 clamp and fix the activated carbon samples; 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 plane-shaped. The claw shape is more suitable for clamping activated carbon of indefinite shape, the needle shape is suitable for clamping activated carbon of fixed shape or surface porous structure, the bowl shape is suitable for clamping activated carbon of spherical shape, and the plane shape is more universal and has a wider range of application. In the experiment, a more suitable auxiliary fixing member is selected according to factors such as the shape of the activated carbon sample. In the present invention, whether it is claw-shaped, needle-shaped, bowl-shaped or plane-shaped, compared with the existing platform structure, that is, the method of placing the activated carbon sample stably on a plane structure, the clamping has the advantage of being more stable, and can make the activated carbon sample accept adsorption in multiple directions of up, down, left and right during testing, instead of the existing platform structure, only the upper surface of the activated carbon sample can be tested, and 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 fixings of different shapes can better adapt to activated carbon samples of various shapes and structures, and improve the stability and reliability of clamping. In addition, auxiliary fixings of claw-shaped, needle-shaped, etc. shapes can also increase the contact area between the activated carbon sample and the test environment to a certain extent compared with the prior art, and improve the accuracy and sensitivity of the test.

[0036] like Figure 3As shown, in order to determine when the auxiliary fixing part 6 is installed in place 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 groove of the first groove 8, and the other end is connected to the limiting ball 10, and 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, and 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 selected as an existing pressure spring, and the spring part 9 can provide pressure to the limiting ball 10 to push the limiting ball 10 so that it is located at the notch. The limiting ball 10 can be selected from plastic or metal materials, which are 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, so that the limiting ball 10 moves into the groove, compressing the spring member 9. When reaching the limiting position, the portion of the limiting ball 10 protruding from the notch of the first groove 8 enters the limiting groove 11, and at this time, the operator can know that the installation has been in place through the sense of the hand, 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 will be 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 the two auxiliary fixing members 6 contact the activated carbon sample. At this time, the lower lifting rod 5 continues to rise, and under the mutual squeezing 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, and the protruding contact 13 enters the contact groove 12 and touches the contact piece in the contact groove 12. The contact 13 obtains 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, thereby improving the efficiency and accuracy of the operation. At the same time, precise control of the lower lifting rod 5 can ensure that the activated carbon sample will not be over-extruded during the clamping process, thus 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-place signal by contact, which can be implemented by common knowledge. The contact signal can be an electrical 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 to form a path, thereby generating an electrical signal, and the controller uses the electrical signal as an in-place signal. Similarly, various other existing forms can be used to achieve the generation of signals as in-place signals by the contact of contacts and contact pieces, to determine 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 with the insertion of the auxiliary fixing member 6 in a variety of existing technical implementations. For example, the structure of the protruding contact 13 can be selected in the form of a stop ball 10, and the protruding contact 13 can be extended and retracted by a spring member, so as to complete the entry into the contact slot 12. Figure 3 As shown. Alternatively, the protruding contact 13 may be a metal spring sheet. When the auxiliary fixing member 6 is inserted into the mounting hole 7, the metal spring sheet is squeezed to be close to 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 state 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, and those skilled in the art may 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, and the limiting ball 10 will squeeze the auxiliary fixing member 6 under the action of the spring member 9, so that the auxiliary fixing member is more stable in the mounting hole 7.

[0042] It also includes a controller 14, a driving 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 a suitable temperature range. The setting of the heating module 17 can realize the precise heating of the activated carbon sample and improve the accuracy and repeatability of the test.

[0043] The output end of the controller 14 is connected to the driving device 15 and the heating module 17 respectively, and is used to control the heating module 17 to heat and control the driving device 15 to perform actions. The input end is connected to the temperature acquisition module 16, and is used to obtain the temperature data collected by the temperature acquisition module 16. The precise control of the controller 14 can realize the automated management of the experimental process, and improve 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 according to the data of the temperature acquisition module 16, and ensure that the experiment is carried out under stable temperature conditions.

[0044] The driving end of the driving device 15 is connected to the lower lifting rod 5; when the controller 14 obtains the lifting signal, the controller 14 controls the driving device 15 to drive the lower lifting rod 5 to lift. In the present invention, the lower lifting rod 5 needs to complete the lifting action and is driven by the driving device 15. The driving device 15 and the lower lifting rod 5 can be implemented by the existing technology. The present invention does not make specific redundant descriptions and limitations on the driving device 15 and the lower lifting rod 5. For example, the lower lifting rod 5 can use a screw rod structure, and the driving device 15 can use a motor. The motor drives the screw rod to rotate, so that the nut moves 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 select other existing structures that can achieve the lifting purpose as the structure of the lower lifting rod, and the driving device can of course also be selected as other power devices such as motors and hydraulic motors.

[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 in real time, such as temperature, time, etc. 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, so that the experimenter can 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, so that the experimenter can 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] Improve detection accuracy: The various shapes of the auxiliary fixings in the clamping mechanism can adapt to activated carbon samples of different shapes and structures, ensuring that the samples are stably clamped during the detection process, avoiding the change of sample position due to loose clamping and affecting the detection results, thereby significantly improving the accuracy of the detection. Compared with the existing platform structure, the clamping method of the present invention enables the activated carbon sample to be adsorbed in multiple directions of up, down, left, and right during the test, avoiding the inaccurate test caused by the lower surface of the sample being blocked in the existing structure, and the comprehensive adsorption detection further improves the accuracy of the test results.

[0048] Ensure installation accuracy and operational convenience: The limit groove on the auxiliary fixing cooperates with the spring part and the limit ball in the mounting hole to accurately determine the installation position of the auxiliary fixing, ensure that it is installed in place, and avoid affecting the experimental results due to improper installation. At the same time, the operator can judge whether the installation is in place by sensing the position of the limit ball with his hand, 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 obtains the in-place signal, and the lower lifting rod stops lifting and lowering, 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 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.
