Description

Technical Field

[0001] The utility model belongs to the technical field of iodine adsorption, in particular to a simple device for measuring gaseous iodine adsorption. Background Art

[0002] Iodine adsorption devices are commonly used in laboratory reaction instruments and are widely used in various industries, including analytical chemistry, nuclear power plants, pharmaceuticals, and chemicals. Measuring gaseous iodine requires adsorption of iodine into the sample being tested while maintaining both quality control accuracy and temperature control precision.

[0003] In existing technical means, the iodine adsorption device is generally composed of an outer shell, an insulation layer, a vacuum pump, a coil spring and other parts. The outer shell prevents heat loss and external influences, the insulation layer is used to reduce heat loss, the vacuum pump is used to maintain the vacuum state of the system, and the coil spring is used to measure the sample adsorption value.

[0004] In current devices, the outer shell is fragile and easily damaged, while the internal coil spring is very easy to oxidize and cannot accurately represent subtle changes, which can easily cause inconvenience when loading the tested sample. In addition, the existing device uses solid adsorption materials to undergo adsorption reactions with solid iodine, which can easily result in incomplete reactions, insufficient adsorption, and unsafe conditions. In addition, the overall device is expensive and overly dependent on electricity and the external environment. If it encounters damage, certain professional knowledge and skills are required for correct operation and maintenance. Unprofessional operation may lead to inaccurate measurement results or even damage the instrument. Utility Model Content

[0005] In order to solve the technical problems of existing iodine adsorption devices, the purpose of the utility model is to provide a simple device for measuring gaseous iodine adsorption, so as to reduce the contact time between the experimenter and the instrument and the possible risks of experiments or operations, ensure the safety of the operator, reduce the test time, and improve the accuracy, precision and sensitivity of weighing analysis, which is of great help to the analysis of trace samples and trace components.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned technical purpose is that the device includes a large glass bottle with an open upper end and a small glass bottle, wherein the large glass bottle serves as a container for carrying solid iodine, and iodine adsorption material is placed in the small glass bottle. The small glass bottle is placed in the large glass bottle through a support structure provided in the large glass bottle. The upper surface of the support structure is flat, and the support structure separates the small glass bottle from the large glass bottle, and the top of the small glass bottle does not contact the bottom of the large glass bottle cap.

[0007] Further optimization, the large glass bottle and the small glass bottle are both cylindrical, the diameter of the mouth of the small glass bottle is smaller than the diameter of the mouth of the large glass bottle, the body of the small glass bottle is less than or equal to half of the body of the large glass bottle, and the small glass bottle can move freely in and out of the large glass bottle.

[0008] Further optimized, the width of the support structure is greater than or equal to the bottle body of the small glass bottle, and smaller than the bottle mouth diameter of the large glass bottle.

[0009] Further optimization, the large glass bottle and the small glass bottle are both made of crystal white material.

[0010] Further optimization is carried out in which the inside of the large glass bottle is coated with anti-corrosion material, and the large glass bottle cap is connected to the ground mouth of the large glass bottle.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1) The small glass bottle of the utility model is placed in the large glass bottle via a support structure provided in the large glass bottle with an open top. The large glass bottle serves as a container for solid iodine, and iodine adsorption material is placed in the small glass bottle. The upper surface of the support structure is flat, and the support structure separates the small glass bottle from the large glass bottle, and the top of the small glass bottle does not contact the bottom of the large glass bottle cap. The separation allows the glass bottle structures to be separated before and after testing, thereby reducing the contact time between the experimenter and the instrument during experiments or operations that may involve risks, thereby ensuring the safety of the operator;

[0013] 2) The large glass bottle and the small glass bottle of the utility model are both cylindrical. The diameter of the mouth of the small glass bottle is smaller than that of the mouth of the large glass bottle. The small glass bottle can be freely moved in and out of the large glass bottle. The diameter of the support structure provided in the large glass bottle is larger than the bottle body of the small glass bottle and smaller than the diameter of the mouth of the large glass bottle. Solid iodine is heated and sublimated into gaseous iodine in the oven. The large glass bottle serves as a container for the solid iodine, which increases the contact area between the solid iodine and the air, thereby enhancing the adsorption of the measuring material in the small glass bottle, reducing the test time, and improving the accuracy, precision and sensitivity of the weighing analysis, which is of great help in the analysis of trace samples and trace components.

[0014] 3) Both the large and small glass bottles of this utility model are made of crystal white material. Compared with traditional quartz glass, crystal white glass is formed by high-temperature melting and has higher stability and density. On the one hand, it prevents the deformation of the glass bottle structure caused by excessive temperature. On the other hand, it is conducive to the adsorption of iodine by the measuring material and its stable existence in the small glass bottle, thereby improving the weighing accuracy and speeding up the weighing speed.

[0015] 4) Compared with large, complex and sophisticated traditional instruments, the utility model saves time and manpower, and has considerable economic benefits; it does not require skilled and highly skilled technicians for maintenance and repair. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] A simple device for measuring gaseous iodine adsorption, such as Figure 1 As shown, the device comprises a large glass bottle 202 and a small glass bottle 204 with open tops. The large glass bottle 202 serves as a container for solid iodine 207, while the small glass bottle 204 contains iodine adsorption material 206. The small glass bottle 204 is positioned within the large glass bottle 202 by a support structure 208 provided within the large glass bottle 202. The top surface of the support structure 208 is flat, ensuring the stable placement of the small glass bottle 204. The support structure 208 separates the large glass bottle 202 from the small glass bottle 204, and the top of the small glass bottle 204 does not contact the bottom of the large glass bottle cap 201. The large glass bottle 202 serves as the reaction vessel for the entire iodine adsorption device, holding the solid iodine 207. By placing the iodine adsorption material 206 within the small glass bottle 204 and preventing direct contact with the solid iodine 207, the iodine adsorption reaction is controlled. When the large glass bottle 202 heats the solid iodine 207 and sublimates it into gaseous iodine 203, the gaseous iodine 203 contacts the iodine adsorption material 206 more completely than the solid iodine 207, thereby enhancing the adsorption effect of the iodine adsorption material 206 in the small glass bottle 204, while improving the accuracy, precision and sensitivity of the weighing analysis, which is of great help to the analysis of trace samples and trace components; the large glass bottle 202 and the small glass bottle 204 are separated and not sticky, so that the large glass bottle 202 and the small glass bottle 204 can be separated before and after the test, thereby reducing the contact time between the experimenter and the instrument and the possible risks of the experiment or operation, thereby ensuring the safety of the operator; and the use of glass bottles as measuring tools instead of steel materials can reduce the difficulty of experimental operation and effectively improve the controllability of the experiment. Compared with traditional steel bottles, they are more green and environmentally friendly and respond to sustainable development.

[0024] like Figure 1 As shown, the large glass bottle 202 and the small glass bottle 204 are both cylindrical. The diameter of the mouth of the small glass bottle 204 is smaller than that of the large glass bottle 202. The body of the small glass bottle 204 is less than or equal to half of the body of the large glass bottle 202. The small glass bottle 204 can move freely in and out of the body of the large glass bottle 202 to avoid safety accidents.

[0025] Specific operation steps: Before the experiment, turn on the heating mechanism (i.e. oven) and set it to 78℃. Figure 4 As shown, take the small glass bottle 204 and accurately weigh its mass using a weighing mechanism (i.e., analytical balance 401), as shown in FIG. Figure 1 As shown, the iodine adsorbent material 206 is then placed in a small glass bottle 204 and its mass is accurately weighed again; during the experiment, as shown Figure 2 As shown, the small glass bottle 204 is placed on the support structure 208 of the large glass bottle 202 and covered with the large glass bottle cap 201 to form a closed system (Note: the solid iodine 207 in the large glass bottle 202 cannot exceed the support structure 208 to prevent adhesion to the small glass bottle 204 and cause errors). The system is placed in a constant temperature oven at 78°C. The solid iodine 207 in the large glass bottle 202 begins to sublime into gaseous iodine 203, and the iodine adsorption material 206 continues to adsorb iodine. Wait for 48 hours; after the experiment is completed, as shown in FIG. Figure 3 As shown, the operator takes the heated iodine adsorption device 104 out of the oven and puts it into a cooling mechanism (i.e., refrigerator) for rapid cooling. After waiting for 5 minutes, as shown in FIG. Figure 4 As shown, after cooling, the iodine adsorption device 303 is removed and the masses of the vial 204 and the iodine-adsorbed material 407 within the vial are measured separately. The difference in mass before and after the experiment is the mass of the adsorbed iodine. The refrigerator's safe and efficient refrigeration system shortens measurement time and prevents iodine sublimation, enhancing the instrument's accuracy.

[0026] To maintain the accuracy of the experiment, the experimenter must keep the table clean and wear masks and gloves during the measurement process to prevent errors caused by human factors. The surface of the oven has a visual glass, which can be used to observe the status of the recording device during the adsorption process and can promptly detect safety issues to improve safety.

[0027] During use, it is important to set the oven temperature to 78°C and the refrigerator temperature to 0°C. These temperatures allow iodine to sublime and desublimate faster, saving time. Operators should wear gloves when removing the glass bottle to prevent burns from high temperatures.

[0028] Furthermore, to ensure experimental accuracy, a vial cap 406 may be placed on vial 204 before the cooling process. This is because the adsorbed iodine will undergo a desorption process after cooling, so vial cap 406 must be kept sealed during the cooling process to prevent iodine volatilization from affecting experimental accuracy. After cooling, and before weighing, vial cap 406 must be removed to avoid affecting the accuracy of the weighing data.

[0029] like Figure 1As shown, the width of the support structure 208 is greater than or equal to the body of the small glass bottle 204 and smaller than the diameter of the mouth of the large glass bottle 202. This provides sufficient support for the small glass bottle 204, preventing it from tilting due to the influence of the gaseous iodine 203 during the measurement process. It also effectively prevents accidental tilting of the small glass bottle 204 and reduces corrosion of the bottom of the small glass bottle 204 by the solid iodine 207.

[0030] like Figure 1 As shown, the large glass bottle 202 and the small glass bottle 204 are both made of crystal white material. Crystal white glass is formed by high temperature melting and has high stability and density, which effectively extends the service life of the device and enhances safety.

[0031] like Figure 1 As shown, the inside of the large glass bottle 202 is coated with an anti-corrosion material 205, which can maintain the structure inside the glass bottle, extend the service life of the device, and prevent other substances such as solid iodine 207 from causing harm to the device; the large glass bottle cap 201 is ground connected to the large glass bottle 202, and the frosted surface is wider. While achieving a relatively good sealing effect, it can effectively prevent safety problems caused by excessive system pressure.

[0032] like Figure 4 As shown, an analytical balance is used as a weighing instrument, and the iodine adsorption amount of the material 407 after iodine adsorption is accurately calculated by the mass difference between the front and rear small glass bottles 204, which effectively simplifies the experimental device and experimental steps and reduces the difficulty of operation. It can also reduce experimental expenses and manpower and material resources, and conform to the theme of green environmental protection.

[0033] It should be noted that the above is only used to illustrate the technical solution of the present invention rather than to limit it. Ordinary technicians in the field should understand that the specific implementation methods of the present invention can be modified or replaced by equivalents with reference to the above embodiments. Based on this purpose, technicians in this field can use other similar mechanical structures to reduce the contact time between experimenters and instruments for experiments or operations that may be risky, ensure the safety of operators, further reduce test time, and improve the accuracy, precision and sensitivity of weighing analysis, which is of great help to the analysis of trace samples and trace components; the glass bottle structure as a measuring instrument is relatively more environmentally friendly and green compared to traditional steel cylinders. Any modifications or equivalent replacements that do not deviate from the spirit and scope of the present invention are within the scope of protection of the claims of the present invention.
