Description

Technical Field

[0001] The invention relates to the technical field of deoxidizer detection, in particular to an intelligent deoxidizer oxygen absorption detection system. Background Art

[0002] The detection principle of the oxygen absorption of the deoxidizer is to place the deoxidizer in a liquid-sealed closed container under normal pressure and temperature conditions. After the deoxidizer reacts chemically with the oxygen in the air, a pressure difference is formed inside and outside the container, causing the liquid level of the closed container to rise. The volume of the rising liquid level is the oxygen absorption volume of the oxygen absorption. The oxygen absorption of the measured deoxidizer is obtained by calculating the liquid level difference before and after the closed container.

[0003] The current method for detecting the oxygen absorption of deoxidizer is as follows: fix the deoxidizer on the bracket, and form a beaker, a measuring cylinder, a bracket, an ear cleaning bulb and a silicone tube as shown in the figure. Fig.13 The test system shown. Use the ear-washing bulb to adjust the page in the measuring cylinder to the reading scale of the measuring cylinder, then pull out the rubber tube from the measuring cylinder, and observe the initial position of the page and the change in the liquid level position under constant temperature and pressure conditions;

[0004] Every 24 hours, replace the measuring cylinder filled with fresh air and repeat the above steps until the liquid level no longer rises significantly within 24 hours.

[0005] The first change in the position of the measuring cylinder page is represented as ∆V1; the second change in the position of the measuring cylinder page is represented as ∆V2; and so on, the nth change in the position of the measuring cylinder page is represented as ∆Vn.

[0006] Taking into account the effect of ambient temperature on the air pressure in the measuring cylinder, a blank control experiment was set up under the same experimental conditions to calibrate the scale change value.

[0007] The oxygen absorption of the sample is calculated as follows: V = ∆V1 + ∆V2 + ... + ∆Vn

[0008] Where: V is oxygen uptake, in milliliters (mL);

[0009] ∆V1-∆Vn is the change in page position from the first to the nth time, in milliliters (mL).

[0010] The above detection methods have certain problems: (1) Manual operation is cumbersome; (2) There is no automation and traceability; (3) Manual readings result in errors; (4) The deoxidizer is directly exposed to the air due to the repeated ventilation, resulting in errors; (5) Data cannot be recorded in real time; (6) The use of water seals will cause the oxygen absorption of the deoxidizer to be slightly less than the actual measured value, but the use of oil baths is not easy to clean. At the same time, when placing the deoxidizer for testing, most of them are placed manually. At the same time, when the depth of the test bottle is deep, it is necessary to use tools to place it. Therefore, there are certain limitations when placing the deoxidizer for testing. Therefore, it is urgent to improve and perfect the above problems. Summary of the invention

The connecting frame 26 is installed on the inner wall of the detection bottle 9. The left end of the elastic band body 19 is installed on the surface of the fixing piece 29. The outer surface of the elastic band body 19 is in contact with the outer surfaces of the limiting roller 31 and the auxiliary roller 34. First, the computer body 2, the bottom plate 4 and the digital pressure sensor body 14 on the top surface of the detection bottle 9 The temperature and humidity sensor bodies 40 are all electrically connected, and the digital pressure sensor body 14 and the temperature and humidity sensor body 40 can transmit the collected data to the computer body 2 and the PLC control cabinet 5. The overall data collection effect is relatively accurate. This design places twenty groups of test bottles 9 inside the five groups of constant temperature frames 7 and the constant temperature bath 8, and the sizes of the test bottles 9 can be different. When testing, first place the deoxidizer to be tested on the surface of the sample tray 23, and then cover the sealing plate 16. The sealing between the sealing plate 16 and the test bottle 9 is good, and then the computer body 2 can record the data collected by the digital pressure sensor body 14 and the temperature and humidity sensor body 40, so that the temperature, humidity, pressure, and residual oxygen content can be measured in real time.At the same time, the outer surface of the air inlet pipe 10 is provided with a pneumatic valve body 13 for controlling the inlet and outlet of gas, which can quantitatively fill the required gas into the detection bottle 9 to meet different experimental requirements. Compared with the above-mentioned manually constructed instruments, this design has the advantages of easy use, accurate readings, no need to change the medium, and automatic calibration; the deoxidizer oxygen absorption detection system has a high degree of automation, can set relevant parameters according to user needs, and automatically measure and calculate the total oxygen absorption of the sample, and has the advantage of unattended operation; according to user needs, multiple deoxidizer samples can be tested simultaneously within a unit time, greatly improving work efficiency, and innovatively using an electronic control system to monitor the changes in air pressure and oxygen concentration in the closed detection bottle 9 in real time to calculate the oxygen absorption, and the data is in the form of electronic data The mode of the data is recorded in the computer system, which completely avoids the inaccurate readings that exist during manual readings, the inability to monitor in real time, and the problem that the measured value in the water seal is slightly smaller than that in the oil seal. At the same time, the device also solves the problem of low experimental work efficiency. Since the oxygen absorption test of the deoxidizer is time-consuming, depending on the type of sample, some samples may even take up to 240 hours. If the number of experimental samples is increased at the same time, the efficiency of the experiment per unit time can be improved. Therefore, the oxygen absorption detection system of the deoxidizer proposed in the present invention can be appropriately expanded as needed, and the number of detection bottles 9 can be increased. The oxygen absorption test of multiple deoxidizers can be carried out simultaneously per unit time. A set of detection system can do at least one hundred groups of samples at the same time. When conducting actual detection, first First, hold the pulling column 18, and by pulling the pulling column 18, the sealing plate 16 will rotate through the rotating shaft 15, and then the sealing plate 16 will rotate with the rotating shaft 15 as the center, so that the sealing plate 16 will pull the elastic belt body 19 to move. At this time, the outer surface of the elastic belt body 19 will fit on the back of the auxiliary roller 34 and the limiting roller 31. The position of the elastic belt body 19 can be limited by the design of the auxiliary roller 34 and the limiting roller 31. Then, since the elastic belt body 19 is pulled, and the left end of the elastic belt body 19 is installed on the surface of the fixing member 29, the fixing member 29 and the mounting plate 28 can be pulled. At this time, after the mounting plate 28 rotates, it will also drive the connecting plate 24 to rotate. Since the upper and lower ends of the connecting plate 24 are both installed There is a spring shaft 25, so that the connecting plate 24 will drive the iron block 22 and the sample tray 23 to rotate, so that the sample tray 23 can rotate with the connecting plate 24. When the connecting plate 24 rotates to a suitable angle, the connecting plate 24 will move to the vicinity of the pick-up and placement groove 39, and then place the deoxidizer on the surface of the sample tray 23, so that rapid placement can be completed. This feeding method solves the problem of needing to screw out the cover body before feeding. At the same time, when the bottle body is deep, the placement of the deoxidizer requires the aid of tools. This design does not require the aid of tools for placement. The speed of placing the deoxidizer is fast, and then the pull column 18 is slowly released. Since the elastic belt body 19 is elastic, no tension is applied to the elastic belt body 19.At this time, the elastic band body 19 will slowly shrink, and then the mounting plate 28 and the fixing member 29 will slowly return to their original positions, and finally the connecting plate 24 and the iron block 22 will return to their original positions, so that the sample tray 23 will also return to its original position. At this time, the deoxidizer on the surface of the sample tray 23 can be stably placed, and at the same time, the elastic band body 19 has elasticity, so that the elastic band body 19 will also stably pull the sealing plate 16, and at this time, the sealing effect between the sealing plate 16 and the placement groove 39 is good, and at the same time, the elastic design of the spring shaft 25 can also well restore the sample tray 23 with the deoxidizer placed thereon to its original position, and at the same time, when returning to its original position, the outer surface of the iron block 22 will contact the inner wall of the magnet stone 21, so that the iron block 22 and the magnet stone 21 are magnetically attracted to each other, and the overall magnetic attraction effect is good, so that the iron block 22 is overall stable on the surface of the magnet stone 21, which enhances the stability of the sample tray 23 during detection, and the design can facilitate the placement of the deoxidizer, and the overall operation efficiency is high. At the same time, after the deoxidizer is placed, the sealing plate 16 is moved by the elastic band body 19 and The elasticity of the spring shaft 25 can automatically restore to its original position for detection, and the overall linkage effect is relatively good. Subsequently, after the sealing plate 16 is rotated, the movable shaft 37 can be rotated on the inner surface of the sealing plate 16, so that the conveying block 38 can be overlapped on the surface of the sample tray 23, and then the deoxidizer can be directly placed on the surface of the movable shaft 37, so that the deoxidizer will slide from the surface of the movable shaft 37 to the surface of the sample tray 23, so that the overall placement of the deoxidizer is simpler, and the position of the elastic belt body 19 can be limited by the cooperation of the limiting roller 31 and the limiting frame 33. Through the design of the spring shaft 25, when the sealing plate 16 does not apply tension, the spring shaft 25 can drive the connecting tube 27 and the fixing member 29 to rotate, so that the sealing plate 16 is pulled by the elastic belt body 19, so that the sealing plate 16 body can be attached to the outer surface of the detection bottle 9. At this time, the detection bottle 9 is in a sealed state, and the sealing plate 16 is always attached to the detection bottle 9 by the tension of the elastic belt body 19 to seal the detection bottle 9;

[0044] Testing steps:

[0045] ① After placing the deoxidizer on the sample tray 23, the sealing plate 16 will automatically cover it to ensure its sealing.

[0046] ② Click the start button on the desktop of the computer body 2 to record the temperature, humidity, pressure and residual oxygen content in real time.

[0048] Assume that initially: P1V1=n1RT1....①

[0049] At any time: P2V2=n2RT2....②

[0050] Because V1=V2; T1=T2, so P1 / P2=n1 / n2

[0051] And because the oxygen absorption V = (1- (n2 / n1)) * V1, so V = (1- (p2 / p1)) * V1

[0052] P1-The initial gas pressure in the reactor, i.e. atmospheric pressure, unit (Pa).

[0053] P2-Real-time gas pressure in the reactor, unit (Pa).

[0054] v1-Real-time gas volume inside the reactor, i.e. reactor volume, unit (m3).

[0055] V2-The volume of gas inside the reactor at the end of the reaction, that is, the volume of the reactor, unit (m3).

[0056] T1-initial temperature inside the reactor, unit (K).

[0057] T2-Real-time temperature inside the reactor, unit (K).

[0058] n1-the amount of initial gas substance inside the reactor, unit (mol).

[0059] n2-The real-time amount of gaseous substances inside the reactor, unit (mol).

[0060] Ideal gas constant, unit (J / (mol·K)). V-oxygen absorption

[0061] ④ Oxygen absorption is also equal to: volume * (20.9-residual oxygen content) * %

[0062] It can meet the needs of various types of deoxidizers for oxygen absorption analysis and real-time monitoring.

[0063] Working principle: When the staff uses this device, first connect the device to an external power supply to provide power support for the device. First, the computer body 2, the bottom plate 4 and the digital pressure sensor body 14 and the temperature and humidity sensor body 40 on the top of the detection bottle 9 are electrically connected. The digital pressure sensor body 14 and the temperature and humidity sensor body 40 can transmit the collected data to the computer body 2 and the PLC control cabinet 5. The overall data collection effect is relatively accurate. This design places twenty groups of detection bottles 9 inside the five groups of constant temperature frames 7 and the constant temperature bath 8, and the detection bottles 9 are The size can be different. When testing, first place the deoxidizer to be tested on the surface of the sample tray 23, then cover the sealing plate 16, the sealing plate 16 and the test bottle 9 have good sealing performance, and then the computer body 2 can record the data collected by the digital pressure sensor body 14 and the temperature and humidity sensor body 40, so that the temperature, humidity, pressure, and residual oxygen content can be measured in real time. At the same time, the outer surface of the air inlet pipe 10 is provided with a pneumatic valve body 13 for controlling the inlet and outlet of the gas, and the required gas can be quantitatively filled into the test bottle 9 to meet different experimental requirements;

[0064] During the actual test, first hold the pulling column 18, and by pulling the pulling column 18, the sealing plate 16 will rotate through the rotating shaft 15, and then the sealing plate 16 will rotate around the rotating shaft 15 as the center, so that the sealing plate 16 will pull the elastic belt body 19 to move. At this time, the outer surface of the elastic belt body 19 will fit on the back of the auxiliary roller 34 and the limiting roller 31. The position of the elastic belt body 19 can be limited by the design of the auxiliary roller 34 and the limiting roller 31. Then, due to the pulling of the elastic belt body 19, the left end of the elastic belt body 19 is installed on the surface of the fixing member 29. Thereby, the fixing member 29 and the mounting plate 28 can be pulled. At this time, after the mounting plate 28 rotates, the connecting plate 24 will also be driven to rotate. Since the upper and lower ends of the connecting plate 24 are both equipped with spring shafts 25, the connecting plate 24 will drive the iron block 22 and the sample tray 23 to rotate, so that the sample tray 23 can rotate with the connecting plate 24. When the connecting plate 24 rotates to a suitable angle, the connecting plate 24 will move to the vicinity of the pick-up and placement groove 39, and then place the deoxidizer on the surface of the sample tray 23, so that rapid placement can be completed, and then the pulling column 18 is slowly released. The elastic belt body 19 is elastic, so that after no tension is applied to the elastic belt body 19, the elastic belt body 19 will slowly shrink, and then the mounting plate 28 and the fixing member 29 will slowly return to their original positions, and finally the connecting plate 24 and the iron block 22 will return to their original positions, so that the sample tray 23 will also return to their original positions. At this time, the deoxidizer on the surface of the sample tray 23 can be stably placed. At the same time, the elastic belt body 19 is elastic, so that the elastic belt body 19 will also stably pull the sealing plate 16. At this time, the sealing effect between the sealing plate 16 and the pick-up and placement groove 39 is better, and at the same time, the elasticity of the spring shaft 25 The design can also well restore the sample tray 23 with the deoxidizer placed in it to its original position. At the same time, when restoring to its original position, the outer surface of the iron block 22 will contact the inner wall of the magnet stone 21, so that the iron block 22 and the magnet stone 21 are magnetically attracted to each other, and the overall magnetic attraction effect is good, so that the iron block 22 is overall stable on the surface of the magnet stone 21, and the stability of the sample tray 23 during detection is enhanced. This design can facilitate the removal and placement of the deoxidizer. At the same time, after the deoxidizer is removed and placed, the sealing plate 16 can automatically restore to its original position for detection through the elasticity of the elastic band body 19 and the spring shaft 25. The above is all the working principles of the present invention.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
