Description

Technical Field

[0001] This utility model relates to the field of adsorption-desorption experimental technology, and in particular to a high-efficiency adsorption-desorption device for laboratory use. Background Technology

[0002] A high-efficiency adsorption-desorption device for laboratory use is an experimental device used to achieve efficient adsorption and desorption of target substances. It is commonly used in scientific research, environmental remediation, chemical separation and other fields. In existing devices, the adsorption tube is usually fixed to the inlet and outlet, and the carbon nanotube inside the adsorption tube is designed to be detachable. This design means that after the experiment, the experimenter can only calculate the mass of the adsorbed substance by calculating the weight of the input and output substances. When verifying the actual mass of impurities adsorbed by the carbon nanotube, the experimenter can only remove the carbon nanotube and weigh it. However, some impurities will remain on the tube wall during the experiment, resulting in a deviation between the mass of impurities adsorbed by the carbon nanotube and the actual calculated mass of impurities.

[0003] The present invention aims to provide a high-efficiency adsorption-desorption device for laboratory use to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology as described in the background section, and to propose a high-efficiency adsorption-desorption device for laboratory use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency adsorption-desorption device for laboratory use includes an air inlet mechanism, an air inlet pipe, and an adsorption tube. The air inlet mechanism has an air inlet pipe that is connected through one side, and an adsorption tube is provided at the lower end of the air inlet pipe. An air inlet plug is connected through the bottom of the air inlet pipe. Rubber plugs are fixedly connected to both the upper and lower ends of the adsorption tube, and a base is provided at the bottom of the adsorption tube. An air outlet plug is provided on the upper surface of the base, and a flexible tube is fitted inside the base. The flexible tube is connected through the base, and a connecting pipe is connected through one side of the flexible tube. The other end of the connecting pipe is connected through the exhaust port. An activated carbon adsorption tube is fitted inside the adsorption tube.

[0007] Preferably, a movable base is fitted and connected to the inner side of the base, and the air outlet plug is located on the upper surface of the movable base, passing through the movable base and connected to the hose. A spring is fixedly connected to the bottom of the movable base.

[0008] Preferably, the base is cylindrical in shape, with a cylindrical groove at the center and a sliding groove on the surface of the base, the bottom of which is at the same horizontal height as the initial position of the movable base.

[0009] Preferably, the activated carbon adsorption tube is located at the center of the adsorption tube, and a fixing ring is fixedly connected to the outside of the activated carbon adsorption tube. A connecting rod is fixedly connected to the outside of the fixing ring, and the other end of the connecting rod is fixedly connected to the inner wall of the adsorption tube.

[0010] Preferably, the air outlet plug is located at the center of the upper surface of the movable base, and the air outlet plug is equipped with a filter screen inside.

[0011] Preferably, the bottom of the adsorption tube is provided with a stable base with a diameter larger than that of the adsorption tube body, and the diameter of the stable base is smaller than that of the movable base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By setting up an air inlet pipe, an adsorption pipe and a base, the experimenter can directly remove the adsorption pipe from the bottom of the air inlet pipe and weigh it directly after the experiment. In subsequent experiments, the experimenter can directly replace the adsorption pipe with an unused one, avoiding the deviation between the mass of impurities adsorbed by the carbon tube and the actual calculated mass of impurities during the verification process. At the same time, the experimenter can retain the experimental data by keeping the adsorption pipe.

[0014] 2. By setting a rubber stopper and a movable base, when installing the adsorption tube, the experimenter can quickly align the adsorption tube with the air inlet plug by retracting the movable base, which simplifies the installation process. At the same time, the installed adsorption tube can fit more tightly with the air inlet and outlet plugs, preventing experimental gas from leaking to the outside from the connection between the adsorption tube and the air inlet and outlet plugs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example

[0025] Reference Figure 1-4A high-efficiency adsorption-desorption device for laboratory use includes an inlet mechanism 1, an inlet pipe 2, and an adsorption tube 3. The inlet mechanism 1 consists of a mixing chamber and a heating chamber, with the heating chamber located between the mixing chamber and the adsorption tube 3. The mixing chamber and the heating chamber are connected by a connecting gas pipe, and a flow meter is installed on the outside of the connecting gas pipe. A gas delivery pipe is located on the left side of the mixing chamber, and a feeding port is located at the top of the mixing chamber. When using this device, the experimenter can input the required gas into the mixing chamber through the gas delivery pipe, and at the same time, add the required experimental materials through the feeding port according to the experimental situation. The gas is mixed with the materials and the input gas through the gas delivery pipe, and then the experimental gas is input into the heating chamber through the connecting gas pipe. Then, the gas is input into the adsorption tube 3 through the inlet pipe 2 for adsorption experiments. After the adsorption experiment is completed, if desorption treatment is required, the operator can heat the input gas by activating the heating component inside the heating chamber, and then complete the desorption treatment by inputting heated air.

[0026] An air intake pipe 2 is connected to one side of the air intake mechanism 1, and an adsorption pipe 3 is provided at the lower end of the air intake pipe 2. An air intake plug 5 is connected to the bottom of the air intake pipe 2. Rubber plugs 6 are fixedly connected to both the upper and lower ends of the adsorption pipe 3, and a base 4 is provided at the bottom of the adsorption pipe 3. An air outlet plug 7 is provided on the upper surface of the base 4, and a flexible hose 12 is fitted inside the base 4. The flexible hose 12 is connected to the base 4, and a connecting pipe 13 is connected to one side of the flexible hose 12. The other end of the connecting pipe 13 is connected to the exhaust port 9. An activated carbon adsorption pipe 10 is fitted inside the adsorption pipe 3. When the experimenter needs to enter... During the adsorption-desorption experiment, the experimenter can place the adsorption tube 3 on the upper surface of the base 4, insert the inlet plug 5 at the bottom of the inlet pipe 2 into the rubber plug 6 at the upper end of the adsorption tube 3, and at the same time insert the outlet plug 7 into the rubber plug 6 at the bottom of the adsorption tube 3, so that the experimental gas input into the inlet pipe 2 can be input into the interior of the adsorption tube 3 through the inlet plug 5, and then perform adsorption through the activated carbon adsorption tube 10. At the same time, the gas input into the adsorption tube 3 can enter the interior of the flexible tube 12 through the movable base 8, and then be input into the exhaust port 9 and discharged to the outside through the flexible tube 12 and the connecting pipe 13.

[0027] It should be noted that the rubber stoppers 6 at the upper and lower ends of the adsorption tube 3 are similar to the rubber stoppers of an infusion bottle. When the air inlet plug 5 and the air outlet plug 7 are inserted into the rubber stopper 6, the rubber stopper 6 can fit tightly with the air inlet plug 5 and the air outlet plug 7 through its own elasticity, filling the tiny gaps after the air inlet plug 5 and the air outlet plug 7 are inserted into the rubber stopper 6, thereby preventing the leakage of experimental gas inside the device.

[0028] A movable base 8 is fitted inside the base 4, and the air outlet 7 is located on the upper surface of the movable base 8, passing through the movable base 8 and connecting to the hose 12. A spring 11 is fixedly connected to the bottom of the movable base 8. The base 4 is cylindrical in shape, with a cylindrical groove in the center. A sliding groove is formed on the surface of the base 4, and the bottom of the sliding groove is at the same level as the initial position of the movable base 8. This design allows the experimenter to tilt the adsorption tube 3 during installation, sliding the bottom of the adsorption tube 3 through the sliding groove to the top of the movable base 8. Insert the air outlet plug 7 into the bottom of the adsorption tube 3, so that the bottom of the adsorption tube 3 is tightly against the movable base 8 and the adsorption tube 3 is pressed down, so that the movable base 8 retracts downward into the interior of the base 4. At this time, the experimenter can adjust the position of the adsorption tube 3 so that the adsorption tube 3 is perpendicular to the movable base 8. Then the experimenter can slowly release the adsorption tube 3, so that the spring 11 rebounds and pushes the adsorption tube 3 upward through the movable base 8, so that the air inlet plug 5 is inserted into the rubber plug 6 at the upper end of the adsorption tube 3. This allows the adsorption tube 3 to fit more tightly against the air inlet plug 5 and the air outlet plug 7, while simplifying the installation process of the adsorption tube 3.

[0029] The activated carbon adsorption tube 10 is located at the center of the adsorption tube 3, and a fixing ring is fixedly connected to the outside of the activated carbon adsorption tube 10. A connecting rod is fixedly connected to the outside of the fixing ring, and the other end of the connecting rod is fixedly connected to the inner wall of the adsorption tube 3. The cross-section of the connecting ring is circular, and multiple hollow holes are provided through the surface of the connecting ring. This allows the experimental gas to pass through the hollow holes while the connecting ring fixes the activated carbon adsorption tube 10, thereby reducing the impact of the connecting ring on the flow of the experimental gas.

[0030] The air outlet plug 7 is located at the center of the upper surface of the movable base 8, and the air outlet plug 7 is equipped with a filter screen inside. This design allows the filter screen to prevent particles generated during desorption from falling into the inside of the hose 12 through the air outlet plug 7 during the desorption experiment.

[0031] The bottom of the adsorption tube 3 is provided with a stable base with a diameter larger than that of the main body of the adsorption tube 3, and the diameter of the stable base is smaller than that of the movable base 8. Through this design, the adsorption tube 3 can still tilt on the upper surface of the movable base 8 when the movable base 8 is in a retracted state.

[0032] Working principle: When the experimenter needs to conduct an adsorption-desorption experiment, the experimenter can place the adsorption tube 3 on the upper surface of the base 4, insert the air inlet plug 5 at the bottom of the air inlet pipe 2 into the rubber plug 6 at the upper end of the adsorption tube 3, and at the same time insert the air outlet plug 7 into the rubber plug 6 at the bottom of the adsorption tube 3, so that the experimental gas input into the air inlet pipe 2 can be input into the interior of the adsorption tube 3 through the air inlet plug 5, and then perform adsorption through the activated carbon adsorption tube 10. At the same time, the gas input into the adsorption tube 3 can enter the interior of the flexible tube 12 through the movable base 8, and then be input into the exhaust port 9 and discharged to the outside through the flexible tube 12 and the connecting pipe 13.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
