Description

Technical Field

[0001] This utility model relates to the field of measuring device technology, specifically to a device for measuring the adsorption rate of activated carbon with adjustable gas flow rate. Background Technology

[0002] An activated carbon adsorption rate measuring device with adjustable gas flow rate is an experimental apparatus used to study the adsorption performance of activated carbon for specific gases under different conditions. This equipment is commonly used in environmental science, chemical engineering, and other fields to evaluate the application effects of activated carbon in air purification, waste gas treatment, and other applications.

[0003] When using activated carbon adsorption rate measuring equipment, it is necessary to ensure that the gas to be treated is in full contact with the activated carbon. However, if the activated carbon is not evenly distributed or the gas to be tested is transported in a relatively uniform position, the efficiency of activated carbon adsorption can be easily affected, which may affect the measurement results. Therefore, we propose an activated carbon adsorption rate measuring equipment with adjustable gas flow rate. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: an activated carbon adsorption rate measuring device with adjustable gas flow rate, including a support base 3 and a holding mechanism 1 for supporting activated carbon. Threaded tubes 2 are fixedly installed at the top and bottom of the holding mechanism 1. A detection gas supply mechanism 4 for adjusting and delivering the gas to be tested is provided at the top of the support base 3. The detection gas supply mechanism 4 is threadedly connected to the threaded tube 2 at the bottom. A top end cap 5 is threadedly connected to the threaded tube 2 at the top. A leveling mechanism 6 for leveling the activated carbon inside the holding mechanism 1 is provided on the top end cap 5. An adsorption detection tube 7 is inserted through the top end cap 5.

[0019] The set-in holding mechanism 1 can support the activated carbon, and the set-in leveling mechanism 6 can level the placed activated carbon. This can ensure that the gas to be tested can pass through the activated carbon layer for gas adsorption evenly. The set-in top end cap 5 can be threadedly connected to the threaded tube 2, which can ensure that the holding mechanism 1 and the top end cap 5 are sealed. This allows the gas adsorbed by the activated carbon to pass through the adsorption detection tube 7 for adsorption and detection. The set-in detection gas supply mechanism 4 can evenly deliver the gas to contact the activated carbon for adsorption, and the set-in flow control valve 13 can control the gas flow rate delivered by the detection gas supply mechanism 4 to ensure that the gas can fully contact and adsorb the activated carbon.

[0020] Please see Figure 1 and Figure 2 The holding mechanism 1 includes a bearing sleeve 8, a placement plate 9, and a feeding groove 10. The placement plate 9 is fixedly installed inside the bearing sleeve 8. Multiple feeding grooves 10 are opened through the placement plate 9. Threaded tubes 2 are fixedly installed on the top and bottom of the outer wall of the bearing sleeve 8.

[0021] The activated carbon used for gas adsorption is placed on the placement plate 9, and the multiple sets of feeding grooves 10 opened on the placement plate 9 can facilitate the gas to be detected to come into contact with the activated carbon through the feeding grooves 10.

[0022] Please see Figure 1 , Figure 2 and Figure 3The detection gas supply mechanism 4 includes a connecting threaded sleeve 11, a gas supply pipe 12, and a flow control valve 13. The connecting threaded sleeve 11 is fixedly installed on the top of the support base 3. The connecting threaded sleeve 11 is threadedly connected to the threaded pipe 2 at the bottom. The gas supply pipe 12 is provided through the inside of the connecting threaded sleeve 11. The flow control valve 13 is provided on the outside of the gas supply pipe 12. The detection gas supply mechanism 4 also includes a diversion pipe 14 and a diversion groove 15. Multiple sets of annular diversion pipes 14 are fixedly connected to the outside of the gas supply pipe 12. Multiple sets of diversion grooves 15 are provided through the diversion pipes 14.

[0023] The gas to be adsorbed is transported through the gas supply pipe 12, and the flow control valve 13 can control the flow rate of the gas supplied by the gas supply mechanism 4 to ensure that the gas can fully contact and adsorb the activated carbon. The gas then transported through the gas supply pipe 12 can be transported through multiple sets of annular diversion pipes 14 and diversion grooves 15, so that the gas to be adsorbed can be transported evenly and fully contact and adsorbed with the activated carbon.

[0024] Please see Figure 1 and Figure 4 The leveling mechanism 6 includes a fixed bearing 16, a rotating shaft 17, a knob 18, an adjusting rod 19, an adjusting frame 20, and a leveling plate 22. The fixed bearing 16 is fixedly installed on the top of the top end cover 5. The rotating shaft 17 is rotatably connected inside the fixed bearing 16. The knob 18 is fixedly connected to the top of the rotating shaft 17. The adjusting rod 19 is fixedly connected to the bottom of the rotating shaft 17. The adjusting frame 20 is slidably connected to the outside of the adjusting rod 19. The leveling plate 22 is fixedly connected to one side of the adjusting frame 20. The adjusting frame 20 is threaded with a locking bolt 21 that contacts the outer wall of the adjusting rod 19. The cross-sections of the adjusting rod 19 and the adjusting frame 20 are both rectangular.

[0025] The height of the plate 22 is adjusted according to the amount of activated carbon added. First, the locking bolt 21 is rotated to move the adjusting frame 20 up and down along the adjusting rod 19. After the movement is completed, the locking bolt 21 is tightened to fix the height of the plate 22. Then, the knob 18 is rotated to drive the rotating shaft 17, the adjusting rod 19 and the plate 22 to rotate, so that the activated carbon after it has been added can be leveled.

[0026] In use, the holding mechanism 1 first supports the activated carbon, and the leveling mechanism 6 then levels the activated carbon, ensuring that the gas to be tested can be uniformly adsorbed through the activated carbon layer. The top end cap 5 is threadedly connected to the threaded tube 2, ensuring a seal between the holding mechanism 1 and the top end cap 5. This allows the gas adsorbed by the activated carbon to be adsorbed and detected by the adsorption detection tube 7. The detection gas supply mechanism 4 uniformly delivers the gas to contact and adsorb the activated carbon, and the flow control valve 13 controls the gas flow rate delivered by the detection gas supply mechanism 4, ensuring sufficient contact and adsorption between the gas and the activated carbon. The activated carbon for gas adsorption is placed on the placement plate 9, and the multiple sets of feeding slots 10 on the placement plate 9 facilitate the flow of the gas to be tested. The gas to be adsorbed is fed into the tank 10 and comes into contact with the activated carbon. The gas is then transported through the gas supply pipe 12. The flow control valve 13 controls the flow rate of the gas supplied by the gas supply mechanism 4 to ensure that the gas can fully contact and adsorb the activated carbon. The gas then transported through the gas supply pipe 12 can be transported through multiple sets of annular diversion pipes 14 and diversion tanks 15. This ensures that the gas to be adsorbed is transported evenly and fully contacts and adsorbs the activated carbon. The height of the plate 22 is adjusted according to the amount of activated carbon placed in. First, the locking bolt 21 is rotated to move the adjusting frame 20 up and down along the adjusting rod 19. After the movement is completed, the locking bolt 21 is tightened to fix the height of the plate 22. Then, the knob 18 is rotated to drive the rotating shaft 17, the adjusting rod 19 and the plate 22 to rotate. This allows the activated carbon to be leveled after it has been placed in the tank.
