Description

Technical Field

[0001] The present invention relates to conductivity measurement technology, and particularly to a degassed conductivity meter. Background Art

[0002] A conductivity meter is an instrument used to measure the conductivity of a solution. Conductivity is a physical quantity that measures the ability of a solution to conduct an electric current and is usually used to indirectly evaluate the concentration of electrolytes in the solution. It has a wide range of applications in various fields such as environmental monitoring, water quality analysis, industrial process control, and laboratory research.

[0003] Traditional conductivity measurement methods usually rely on placing the solution to be measured in a container and directly measuring it by immersing the probe of the conductivity meter into the solution. However, in the actual operation process, this method faces several significant technical challenges: First, the gases dissolved in the solution (such as carbon dioxide CO 2 ) will have a significant interference on the conductivity measurement, resulting in a higher or fluctuating measured value. This is because these gases dissolve in water to form weak electrolytes, increasing the ion concentration of the solution, thus wrongly increasing the measured conductivity value. Especially in the case of high-precision measurements, this error may be unacceptable. Second, after each measurement, in order to ensure the accuracy of the next measurement, the probe must be thoroughly cleaned. Currently, the common practice is to manually clean it with distilled water, which is not only time-consuming and laborious but also difficult to ensure complete removal of the substances remaining from the previous measurement. Especially for samples with high viscosity or easy deposition, the cleaning effect is often not ideal, thus affecting the accuracy of subsequent measurement results. Summary of the Invention

[0004] In view of this, the present invention provides a degassed conductivity meter, which can solve the drawbacks that when the existing conductivity meter measures the conductivity of a solution, the gases dissolved in the solution will have a significant interference on the conductivity measurement, resulting in a higher or fluctuating measured value, and after each measurement, the operation of manually cleaning the probe with distilled water is not only time-consuming and laborious but also difficult to clean thoroughly.

[0030] See Figure 2 and Figure 3 As shown, the liquid injection and heating mechanism includes a liquid injection pipe 301, a third valve 302 and an electric heater 303; a liquid injection pipe 301 is connected to the top of the first storage tank 2; a third valve 302 is arranged on the liquid injection pipe 301, and the third valve 302 is electrically connected to the control box 15; an electric heater 303 is installed at the bottom of the first storage tank 2, and the electric heater 303 is electrically connected to the control box 15.

[0031] See Figure 2 and Figure 3 As shown, the negative pressure mechanism includes a vacuum pump 701 and a third connecting pipe 702; a vacuum pump 701 is installed on the upper side of the support frame 1. The vacuum pump 701 is located on the upper right side of the sleeve 5, and the vacuum pump 701 is electrically connected to the control box 15; the air inlet of the vacuum pump 701 is connected to the upper right side of the second storage tank 6 through the third connecting pipe 702.

[0033] See Figure 5 and Figure 6As shown in the figure, the translation mechanism includes a first guide rail 1301, a first slider 1302, a lead screw 1303, and a motor 1304; a first guide rail 1301 is provided on the lower side of the support frame 1; a first slider 1302 is slidably provided on the first guide rail 1301, and the right side of the first slider 1302 is connected to the first docking pipe 14; a lead screw 1303 is rotatably provided on the first guide rail 1301, and the first slider 1302 is threadedly connected to the lead screw 1303; a motor 1304 is provided on the upper rear side of the first guide rail 1301, the motor 1304 is electrically connected to the control box 15, and the output shaft of the motor 1304 is connected to the rear end of the lead screw 1303.

[0034] See Figure 7 and Figure 8 As shown in the figure, the guiding mechanism includes a second guide rail 1901, a second slider 1902, and a spring 1903; a second guide rail 1901 is provided inside the support frame 1, a second slider 1902 is slidably provided on the second guide rail 1901, and the second slider 1902 is connected to the second docking pipe 20; a spring 1903 is connected between the rear side of the second slider 1902 and the second guide rail 1901.

[0035] See Figures 6-8 As shown in the figure, the rotating mechanism includes a connecting plate 2101, a rack 2102, and a gear 2103; a connecting plate 2101 is provided on the right side inside the support frame 1; a rack 2102 is connected to the upper left side of the connecting plate 2101; a gear 2103 is installed on the probe 18. When the first docking pipe 14 moves towards the side close to the second docking pipe 20, the first docking pipe 14 will drive the probe 18 and the gear 2103 to move synchronously, so that the gear 2103 moves towards the side close to the rack 2102, thereby making the gear 2103 mesh with the rack 2102.

[0036] In the initial state, the water storage space in the sleeve 5 is filled with an appropriate amount of coolant; When in use, first connect the water pipe filled with distilled water to the rear end of the second docking pipe 20 and make the water pipe filled with distilled water in a non-water flowing state; then control the third valve 302 to open through the control box 15, and then add the solution to be measured into the first storage tank 2 through the liquid injection pipe 301. Next, control the third valve 302 to close through the control box 15, and then control the electric heater 303 to start through the control box 15, so that the electric heater 303 heats the solution in the first storage tank 2. At the same time, control the vacuum pump 701 to start through the control box 15, so that the vacuum pump 701 extracts the air in the second storage tank 6 through the third connecting pipe 702, thereby making the second storage tank 6 in a negative pressure state. After that, control the vacuum pump 701 to close through the control box 15. When the solution in the first storage tank 2 is heated to the boiling state, the dissolved gas in the solution will gradually be discharged through the air outlet pipe 4. In this way, the dissolved gas in the solution can be removed, effectively eliminating the influence of the dissolved gas on the conductivity measurement and improving the accuracy of the subsequent measurement results. After the dissolved gas in the solution is completely removed, control the electric heater 303 to turn off through the control box 15, and at the same time control the first valve 9 to open through the control box 15, so that the hot solution in the first storage tank 2 is sucked into the second storage tank 6 through the U-shaped pipe 8 to transfer the hot solution in the first storage tank 2. After the hot solution in the first storage tank 2 is completely transferred, control the first valve 9 to close through the control box 15. Then use the coolant in the sleeve 5 to cool down the hot solution in the second storage tank 6 to ensure that the solution to be detected is in a specific temperature state and avoid measurement errors caused by temperature differences in the solution. Then control the condenser 1001 and the water pump 1002 to start through the control box 15, so that the water pump 1002 pumps the coolant in the sleeve 5 into the condenser 1001 through the first connecting pipe 1003, so that the condenser 1001 cools down the coolant, and the cooled coolant flows back to the sleeve 5 through the second connecting pipe 1004. In this way, the temperature of the coolant can be reduced, ensuring the cooling effect of the coolant;When the hot solution in the second storage tank 6 is completely cooled, then the control box 15 is used to control the condenser 1001 and the water pump 1002 to close. Then, the control box 15 is used to control the conductivity meter 16 to start. Next, the control box 15 is used to control the second valve 12 to open, so that the solution in the second storage tank 6 drops downward through the drain pipe 11 into the first docking pipe 14, so that the solution passes through the first docking pipe 14 and falls out. When the solution contacts the probe 18 in the first docking pipe 14, the conductivity meter 16 can detect the conductivity of the solution through the probe 18. In this way, the conductivity of the solution can be detected. After the conductivity of the solution is detected, the control box 15 is used to control the conductivity meter 16 to close and the second valve 12 to close. Then, the control box 15 is used to control the motor 1304 to drive the lead screw 1303 to rotate, so that the lead screw 1303 drives the first slider 1302, the first docking pipe 14, the probe 18 and the gear 2103 to move backward, so that the first docking pipe 14 contacts the annular baffle structure on the second docking pipe 20. Then, the distilled water switch in the second docking pipe 20 is opened, so that the water pipe filled with distilled water is in a water passing state, so that the distilled water flows into the second docking pipe 20, and then the distilled water falls into the first docking pipe 14 through the second docking pipe 20 to clean the probe 18. After that, as the first slider 1302, the first docking pipe 14, the probe 18 and the gear 2103 continue to move backward, the first docking pipe 14 will drive the second docking pipe 20 and the second slider 1902 to move backward synchronously through the annular baffle structure, and the spring 1903 is compressed. When the gear 2103 meshes with the rack 2102, the rack 2102 will drive the gear 2103 to rotate, so that the gear 2103 drives the probe 18 to rotate, so that the probe 18 is rotationally cleaned, so as to comprehensively clean the outer surface of the probe 18. After the outer surface of the probe 18 is comprehensively cleaned, the distilled water switch in the second docking pipe 20 is closed, so that the water pipe filled with distilled water is in a non-water passing state. Then, the control box 15 is used to control the motor 1304 to drive the lead screw 1303 to reverse and reset, so that the lead screw 1303 drives the first slider 1302, the first docking pipe 14, the probe 18 and the gear 2103 to move forward and reset. During this period, the rack 2102 will drive the gear 2103 and the probe 18 to reverse and reset. When the first docking pipe 14 is separated from the annular baffle structure on the second docking pipe 20, the spring 1903 returns to its original state, and the spring 1903 drives the second slider 1902 and the second docking pipe 20 to move forward and reset. When the gear 2103 is separated from the rack 2102, the gear 2103 and the probe 18 stop reversing. In this way, the outer surface of the probe 18 can be automatically and comprehensively cleaned.

[0037] See Figures 9-11As shown in the figure, it further includes a condensation recovery mechanism, which includes a refrigeration water tank 22, an exhaust pipe 23, a collection cylinder 24 and a drain valve 25; the refrigeration water tank 22 is installed on the upper left side of the support frame 1, and the refrigeration water tank 22 is electrically connected to the control box 15; the exhaust pipe 23 is installed on the refrigeration water tank 22, and the upper right end of the exhaust pipe 23 is communicated with the air outlet pipe 4; the bottom of the exhaust pipe 23 is communicated with the collection cylinder 24, and the collection cylinder 24 is used to collect the water droplets that condense and fall in the exhaust pipe 23; a drain valve 25 is arranged on the collection cylinder 24.

[0038] In the initial state, the refrigeration water tank 22 is filled with an appropriate amount of coolant. By setting the condensation recovery mechanism, when the dissolved gas in the solution gradually discharges through the air outlet pipe 4, the dissolved gas in the solution will discharge along the exhaust pipe 23 through the air outlet pipe 4, and then the control box 15 can be used to control the refrigeration water tank 22 to refrigerate the coolant therein, so that the coolant cools the exhaust pipe 23, thereby cooling the water vapor in the exhaust pipe 23, so that the water vapor condenses to form water droplets attached to the inner wall of the exhaust pipe 23. As the water droplets attached to the inner wall of the exhaust pipe 23 gradually increase, these water droplets will fall downward due to gravity into the collection cylinder 24 for collection. After an appropriate amount of water is collected in the collection cylinder 24, the water collected in the collection cylinder 24 is discharged through the drain valve 25. In this way, the water in the steam state can be cooled and condensed back to the liquid state, realizing the recovery of water.
