Description

Technical Field

[0001] The utility model belongs to the technical field of gas separation testing, and particularly relates to a testing device for CCUS gas separation membranes. Background Technique

[0002] CCUS is the abbreviation of carbon capture, utilization and storage. It refers to a series of technologies aimed at reducing greenhouse gas emissions, especially carbon dioxide emissions. The CCUS gas separation membrane test is a key link in evaluating the performance of gas separation membranes in CCUS technology. The main purpose of the test is to evaluate the carbon dioxide capture efficiency, selectivity, stability and long-term operation performance of the membrane material to ensure that it can meet the requirements of CCUS technology in practical applications. Among them, the gas permeation rate tester is a frequently used test device. The gas permeation rate tester can accurately measure the permeation rate of gas through the gas separation membrane, which is one of the key indicators for evaluating the performance of the membrane material and is directly related to the efficiency and effect of CCUS technology. By accommodating the sample to be tested in the test chamber and allowing the gas to pass through the sample under the action of a pressure difference, the gas permeation rate can be measured, and the selective permeation ability of the membrane material to the target gas can be determined, providing data support for the research and development and optimization of the membrane material.

[0003] The problem of the existing technology is that the test chamber of the gas permeation rate tester is a precision instrument, and the protective cover of the tester host is usually covered on it for protection. If the protective cover is not fixed to a certain extent, the protective cover may shift or loosen during long-term use, resulting in a decline in the protection effect on the test chamber. Summary of the Utility Model

[0004] Aiming at the problems existing in the existing technology, the utility model provides a testing device for CCUS gas separation membranes, which has the advantages of fixing and limiting the protective cover of the tester to prevent the decline of the protection effect after long-term use, and solves the problem that the test chamber of the existing gas permeation rate tester is a precision instrument, and the protective cover of the tester host is usually covered on it for protection. If the protective cover is not fixed to a certain extent, the protective cover may shift or loosen during long-term use, resulting in a decline in the protection effect on the test chamber.

[0021] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0022] As Figures 1 to 4 shown, a CCUS gas separation membrane testing device provided by an embodiment of the present utility model includes a main body 1, an operating table 2, a protective cover 3, a connecting groove 4 and a connecting structure 5.

[0023] Referring to Figure 3 and Figure 4 , the connecting structure 5 includes a moving block 9. The moving block 9 is arranged on the front surface of the main body 1, the outer surface of the moving block 9 is slidably connected to the inner wall of the moving groove 7, a pushing block 10 is fixedly connected to the front surface of the moving block 9, and a moving rod 11 is arranged on the back surface of the moving block 9.

[0024] Adopting the above scheme: By setting the moving block 9, when the pushing block 10 is pushed upward, it can drive the moving block 9 to slide upward in the moving groove 7, so as to synchronously drive the movement of the moving rod 11.

[0025] Referring to Figure 4 , the moving rod 11 is arranged on the inner wall of the connecting groove 4, the front surface of the moving rod 11 is fixedly connected to the back surface of the moving block 9, and two linkage arms 12 are sleeved on the outer surface of the moving rod 11.

[0026] Adopting the above solution: By setting the moving rod 11, the moving rod 11 can be driven by the moving block 9 to move synchronously upward in the connecting groove 4, so as to drive the linkage arm 12 to rotate.

[0027] Reference Figure 4 , the two linkage arms 12 are arranged in a front-back offset manner respectively. Linkage grooves 13 are respectively formed on the surfaces of the two linkage arms 12. The inner walls of the two linkage grooves 13 are respectively sleeved on the outer surface of the moving rod 11. The mutually remote ends of the two linkage arms 12 are respectively rotatably connected to the inner wall of the connecting groove 4 by a rotating shaft. Rotating arms 14 are respectively arranged at the tops of the two linkage arms 12.

[0028] Adopting the above solution: By setting the linkage arm 12, when the moving rod 11 moves upward, it simultaneously presses the inner walls of the two linkage grooves 13, so as to drive the two linkage arms 12 to rotate relatively in a staggered manner, and respectively drive the rotation of the two rotating arms 14.

[0029] Reference Figure 4 , the two rotating arms 14 are respectively fixedly connected to the tops of the mutually remote ends of the two linkage arms 12. Slots 15 are respectively formed in the middles of the two rotating arms 14. Limiting arms 16 are respectively arranged on the mutually remote sides of the two rotating arms 14.

[0030] Adopting the above solution: By setting the rotating arm 14, the two linkage arms 12 respectively drive the two rotating arms 14 to rotate, so as to cooperate with the limiting rod 8 to drive the movement of the two limiting arms 16.

[0031] Reference Figure 4 , the middles of the two limiting arms 16 are respectively slidably connected to the outer surface of the limiting rod 8. The mutually approaching sides of the two limiting arms 16 are respectively in contact with the mutually remote sides of the two rotating arms 14. Limiting springs 17 are respectively fixedly connected to the mutually approaching sides of the two limiting arms 16. The limiting springs 17 are sleeved on the outer surface of the limiting rod 8. Limiting blocks 18 are respectively fixedly connected to the tops of the two limiting arms 16.

[0032] Adopting the above solution: By setting the limiting arm 16, when the two rotating arms 14 rotate, they respectively press the two limiting arms 16, slide away on the surface of the limiting rod 8, and stretch the limiting springs 17. The sliding of the two limiting arms 16 respectively drives the movement away of the two limiting blocks 18.

[0033] Reference Figure 4 , the two limiting blocks 18 are respectively fixedly connected to the mutually approaching sides of the tops of the two limiting arms 16. The mutually approaching ends of the two limiting blocks 18 are respectively inserted into the inner wall of the limiting groove 601.

[0034] Adopt the above solution: By setting the limit blocks 18, when the two limit blocks 18 move away from each other, they can respectively disengage from the inner wall of the limit groove 601 to release the fixed limit on the limit block 6, so that when the protective cover 3 is turned up, it can drive the movement of the limit block 6.

[0035] The working principle of the present utility model:

[0036] During use, push the pressing block 10 upward, so that it drives the moving block 9 to slide upward in the moving groove 7, and simultaneously drives the moving rod 11 to move upward in the connecting groove 4. When the moving rod 11 moves upward, it squeezes the inner walls of the two linkage grooves 13 to drive the two linkage arms 12 to rotate relatively in a staggered manner, and then drives the rotation of the two rotating arms 14 respectively. When the two rotating arms 14 rotate, they respectively squeeze the two limiting arms 16 to slide away on the surface of the limiting rod 8, and stretch the limiting spring 17. The sliding of the two limiting arms 16 drives the two limit blocks 18 to move away. In this way, the two limit blocks 18 respectively disengage from the limit groove 601 to release the fixed limit on the limit block 6. Subsequently, the protective cover 3 can be turned upward through the handle 301, so that it drives the limit block 6 to disengage from the connecting groove 4. Then, the material to be tested is placed on the test cavity 102, and data testing is carried out in cooperation with the control panel 101. After completion, the protective cover 3 is turned down again through the handle 301, so that it drives the limit block 6 to move and is inserted into the connecting groove 4. When the limit block 6 moves downward, it respectively squeezes the two limit blocks 18 to move away, drives the sliding rod of the two limiting arms 16 to move away and stretches the limiting spring 17. When the limit block 6 is completely inserted into the connecting groove 4, the limiting spring 17 pulls the two limiting arms 16 together with the two limit blocks 18 to move closer, so that the two limit blocks 18 are respectively inserted into the limit groove 601 to fix and limit the limit block 6, thereby fixedly connecting the protective cover 3 to the main body 1 to protect the test cavity 102 on the operating table 2.

[0037] In summary: For the CCUS gas separation membrane testing device, through the cooperative work of the main body 1, the operating table 2, the protective cover 3, the connecting groove 4 and the connecting structure 5, it solves the problem that the test cavity of the gas permeability tester is a precision instrument, and the protective cover of the tester host is usually covered above it for protection. If the protective cover is not fixed to a certain extent, the protective cover may shift or loosen during long-term use, resulting in a decline in the protection effect on the test cavity.

[0038] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
