Description

Technical Field

[0001] The invention relates to the field of ion concentration analysis, and in particular to an online fully automatic calcium, magnesium, strontium and barium ion concentration analyzer. Background Art

[0002] In the current caustic soda industry production field and process, if the concentration of calcium, magnesium, strontium and barium ions is too high, the production process will be shut down, resulting in significant losses; therefore, during the electrolysis process, real-time monitoring of calcium, magnesium, strontium and barium ions in refined brine becomes one of the key technologies to ensure the smooth progress of the process.

[0003] The current mainstream detection scheme in the industry is usually: using HNB colorimetric reagent combined with EDTA complexometric titration, and then using a colorimetric analyzer to determine the endpoint and derive the ion concentration value after mechanical or manual stirring. However, this technical system still has the following problems: (1) The detection process is susceptible to multiple interferences such as environmental temperature and humidity fluctuations, reagent batch differences, and operator visual interpretation errors, making it impossible to further improve the accuracy; (2) It is impossible to accurately control the amount and time of the colorimetric reagent, resulting in inaccurate color development results; (3) When the colorimeter has deviations due to lens or light source problems, the existing scheme cannot be quickly replaced. Therefore, there is a need for an online fully automatic calcium magnesium strontium barium ion concentration analyzer that can accurately control the colorimetric reagent and facilitate the rapid replacement of the colorimeter when the results are abnormal, so as to solve the shortcomings of the existing calcium magnesium strontium barium ion concentration analyzer.

[0004] For example, the patent with announcement number CN116008197B provides an online analysis instrument for nickel and cobalt ion concentration and its analysis method. The device includes a sampling mechanism, a measuring mechanism and a control body. The sampling mechanism is used to extract the sample solution to be measured and transport it to the sample chamber. The measuring mechanism measures the total content of nickel and cobalt ions in the initial sample solution by EDTA complexometric titration. This application alleviates the technical problem that the online detection technology and instruments in the prior art cannot simultaneously measure the concentration of nickel and cobalt ions in the nickel and cobalt solvent extraction process. This solution cannot accurately control the dripping amount and dripping time of the color developing reagent; this solution cannot change the sampling flow rate and flow rate when sampling the liquid, so it cannot accurately control the volume of the sampled sample; this solution cannot dynamically adjust the dripping speed of the color developing reagent, and it cannot reduce the dripping rate of the color developing reagent when the reaction reaches the critical value; it cannot quickly replace standard solutions of different concentrations, so it cannot calibrate the instrument.

(3) When the sample liquid flows into the small sample liquid cylinder by inertia, the sample liquid will flow into the inside of the variable sampling shell along the liquid inlet pipe, and also flow into the liquid adding swing head of the output component through the liquid adding pipe, so that the liquid adding swing head applies a certain torque to the reversing shaft, and then the double output electric push rod drives the annular bracket to slide inward, and the two annular brackets drive the two limit disks to slide inward. At this time, the torque applied by the liquid adding swing head to the reversing shaft will assist the reversing shaft to rotate, and the reversing shaft drives the reversing roller and the output main leaf to rotate through the reversing turntable, and the output main leaf drives the two limit disks to slide inward through the output auxiliary leaf, thereby realizing the change of the internal volume of the variable sampling shell. (4) When the liquid level drives the limit bracket and the first screw to rise to the limit position through the suspension ball, the control bracket will also drive the electric card plate to rise to the limit position. At this time, the upper end of the electric card plate will lift the comparison bracket upward for a short distance, so that the card plate is out of contact with the first standard cylinder, thereby facilitating the replacement of the first standard cylinder.

[0043] Working principle of the present invention: Figure 1 and Figure 2 The usage and corresponding scenarios of the present invention are given. The posture control of the calcium magnesium strontium barium ion concentration analysis process is determined by the variable sampling device 3, the dripping device 4 and the comparison device 5. The posture of the variable sampling device 3 is determined by the dripping device 4, and the posture of the comparison device 5 is determined by the dripping device 4. Therefore, the dripping device 4 is the core of the calcium magnesium strontium barium ion concentration analysis.

[0044] Taking the preferred embodiment as an example, when the sample liquid flows into the small sample liquid cylinder 106 of the supporting device 1 by inertia, the sample liquid will diffuse into the interior of the variable sampling housing 302 along the liquid inlet pipe 309, and at the same time diffuse into the liquid adding swing head 316 of the output component 307 through the liquid adding pipe 317, so that the liquid adding swing head 316 applies a certain torque to the reversing shaft 318, and then the dual-output electric push rod 301 drives the two annular brackets 305 to slide inward, and the two annular brackets 305 drive the two limit plates 310 to slide inward. When the liquid adding swing head 316 applies a torque to the reversing shaft 318, the reversing shaft 318 will assist the reversing shaft 318 to rotate, and the reversing roller 319 will drive the output main leaf 315 on the output rotating shell 313 to rotate through the reversing rotating disk 321. The reversing roller 319 drives the output main leaf 315 on the output rotating shell 313 to rotate, and the output main leaf 315 drives the two limit plates 310 to slide inward through the output auxiliary leaf 314, thereby realizing the change of the internal volume of the variable sampling shell 302. When the internal volume of the variable sampling shell 302 becomes smaller, the sample liquid enters from the liquid outlet 311. When the double-output electric push rod 301 drives the annular bracket 305 to slide outward, the annular bracket 305 will also drive the pressure rod 306 to slide inward in the liquid exchange joint 312, and press the residual air in the liquid exchange joint 312 into the cavity of the liquid adding swing head 316, so that the sample liquid in the liquid adding swing head 316 is discharged from the liquid adding tube 317, thereby reducing the torque of the liquid adding swing head 316 on the reversing shaft 318. The bracket 305 drives the pressure rod 306 to slide outward in the liquid exchange joint 312, and sucks the residual air in the liquid adding swing head 316 back into the cavity of the liquid exchange joint 312, so that the sample liquid enters the liquid adding swing head 316 from the liquid adding tube 317, thereby increasing the torque of the liquid adding swing head 316 on the reversing shaft 318; when one annular bracket 305 slides, it will drive another annular bracket 305 to slide in the variable sampling housing 302 through the variable sampling plunger 303 and the variable sampling connecting rod 304, so as to realize the synchronous compensation function;When the sample liquid continues to flow into the dripping device 4, the change in the liquid level of the sample liquid drives the suspension ball 420 to rise, and the suspension ball 420 drives the first screw 414 to lift upward through the limit bracket 422. At the same time, the first screw 414 drives the first nut 415 to rotate, and the first nut 415 drives the second nut 418 to rotate through the control belt 416, and the second nut 418 drives the second screw 419 to lift. Subsequently, during the lifting process of the first screw 414, the pressure sensor at the upper end of the first screw 414 will come into contact with the lower end of the control bracket 413, and the pressure sensor will transmit the signal to the control panel 103, and the control panel 103 will control the water pump in the dripping tank 402 to adjust the storage cylinder 1 04 is sucked into the dripping box 402, so that the adjusting agent and the indicator flow from the rigid straight tube 412 and the flexible bent joint 411 into the control dropper 417, and then drip into the reaction component 410 from the control dropper 417 to realize the adjusting agent and indicator dripping function; lifting the first screw 414 and the second screw 419 will also drive the control bracket 413 to lift, and the control bracket 413 drives the flexible bent joint 411 to bend and fold through the rigid straight tube 412, thereby limiting the flow of the indicator and the adjusting agent at the flexible bent joint 411. In the process of folding the flexible bent joint 411, the acute angle between the rigid straight tube 412 and the horizontal plane will also be The control panel 103 further reduces the flow rate of the indicator and the regulator at the rigid straight tube 412, so that the indicator and the regulator drip more slowly and are easier to control when they are close to the preset dripping amount. When the sample liquid sampling amount reaches the preset value, the suspension ball 420 stops rising, and then the control panel 103 controls the electric push rod on the electric card plate 405 to drive the electric card plate 405 to insert into the dripping card slot 406, thereby realizing the locking function of the control bracket 413. At the same time, the control panel 103 controls the water pump in the dripping tank 402 to stop working to prevent the indicator and the regulator from falling. In the process of the sample liquid flowing into the reaction component 410, the sample liquid will pass through the reaction channel 423 on the partition plate 421, and the reaction The spiral blades 424 in the channel 423 will cause turbulence inside the sample liquid, thereby promoting the mixing of the indicator, the adjusting agent and the sample liquid; when the indicator, the adjusting agent and the sample liquid are completely reacted, the conversion rod 409 is manually pulled to the right to connect the observation box 408 with the reaction component 410, and then the water pump on the second standard cylinder 505 draws the reacted sample liquid into the second standard cylinder 505. At this time, the ray emitter 502 emits a light beam to the standard liquid in the first standard cylinder 504 and the reacted sample liquid in the second standard cylinder 505, and then the light beam is projected onto the absorbance detector on the surface of the comparison base 506 to realize absorbance detection, thereby realizing the analysis and monitoring of the concentration of calcium, magnesium, strontium and barium ions;When the liquid level drives the limit bracket 422 and the first screw 414 to rise to the limit position through the suspension ball 420, the control bracket 413 will also drive the electric card plate 405 to rise to the limit position. At this time, the upper end of the electric card plate 405 will push the comparison bracket 501 upward for a short distance, so that the card plate 503 is out of contact with the first standard cylinder 504, thereby facilitating the replacement of the first standard cylinder 504.

[0046] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, after the sample liquid flows into the small sample liquid cylinder 106 of the supporting device 1 by inertia, the sample liquid will diffuse into the interior of the variable sampling housing 302 along the liquid inlet pipe 309, and at the same time diffuse into the liquid adding swing head 316 of the output component 307 through the liquid adding pipe 317, so that the liquid adding swing head 316 applies a certain torque to the reversing shaft 318, and then the dual-output electric push rod 301 drives the annular bracket 305 to slide inward, and the two annular brackets 305 drive the two limit plates 310 to slide inward. At this time, the torque applied by the liquid adding swing head 316 to the reversing shaft 318 will assist the reversing shaft 318 to rotate, and the reversing shaft 318 drives the reversing roller 319 through the reversing turntable 321. The reversing roller 319 drives the output main leaf 315 on the output rotating shell 313 to rotate, and the output main leaf 315 drives the two limit plates 310 to slide inwardly through the output auxiliary leaf 314, thereby realizing the change of the internal volume of the sampling shell 302. When the internal volume of the sampling shell 302 becomes smaller, the speed at which the sample liquid enters the reaction component 410 from the liquid outlet 311 will be slowed down, so that the sampling amount of the sample liquid can be more accurately controlled; at this time, the annular bracket 305 will also drive the pressure rod 306 to slide inwardly in the liquid exchange joint 312, and press the residual air in the liquid exchange joint 312 into the cavity of the liquid adding swing head 316, so that the sample liquid in the liquid adding swing head 316 is discharged from the liquid exchange joint 312. The liquid adding tube 317 is discharged, thereby reducing the torque of the liquid adding swing head 316 on the reversing shaft 318; when the dual-output electric push rod 301 drives the annular bracket 305 to slide outward, the annular bracket 305 drives the pressure rod 306 to slide outward in the liquid changing joint 312, and the residual air in the liquid adding swing head 316 is sucked back into the cavity of the liquid changing joint 312, so that the sample liquid enters the liquid adding swing head 316 from the liquid adding tube 317, thereby increasing the torque of the liquid adding swing head 316 on the reversing shaft 318; when one annular bracket 305 slides, it will drive the other annular bracket 305 to slide in the reversing housing 302 through the reversing plunger 303 and the reversing connecting rod 304, to A synchronous compensation function is realized; the motor 107 drives the first gear 108 to rotate, the first gear 108 drives the second gear 308 to rotate, the second gear 308 drives the output rotating shell 313 of the output component 307 to rotate, and the output rotating shell 313 drives the output main leaf 315 and the output auxiliary leaf 314 to rotate between the two limit disks 310, so that the sample liquid is transferred from the liquid outlet 311 on the right side of the variable sampling shell 302 to the reaction component 410; the baffle 320 is used to limit the rolling range of the reversing roller 319 on the reversing turntable 321; the auxiliary leaf body 322 is used to be hinged with the output main leaf 315; the auxiliary leaf slider 323 is used to be slidably connected with the end face of the limit disk 310.

[0047] like Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, when the sample liquid continues to flow into the dripping device 4, the change in the liquid level of the sample liquid drives the suspension ball 420 to rise, and the suspension ball 420 drives the first screw 414 to lift upward through the limit bracket 422. At the same time, the first screw 414 drives the first nut 415 to rotate, and the first nut 415 drives the second nut 418 to rotate through the control belt 416. The second nut 418 drives the second screw 419 to lift. Subsequently, during the lifting process of the first screw 414, the pressure sensor at the upper end of the first screw 414 will come into contact with the lower end of the control bracket 413, and the pressure sensor will transmit the signal to the control panel 103, and the control panel 103 will control the dripping box 4. The water pump in 02 sucks the adjusting agent in the adjusting storage cylinder 104 and the indicating storage cylinder 105 and the indicator into the dripping tank 402, so that the adjusting agent and the indicator flow into the control dripping tube 417 from the rigid straight tube 412 and the flexible bent joint 411, and then drip into the reaction component 410 from the control dripping tube 417 to realize the adjusting agent and indicator dripping function; lifting the first screw 414 and the second screw 419 will also drive the control bracket 413 to lift upward in the dripping bracket 401, and the control bracket 413 drives the flexible bent joint 411 to bend and fold through the rigid straight tube 412, thereby limiting the flow of the indicator and the adjusting agent at the flexible bent joint 411, During the folding process of the flexible bent joint 411, the acute angle between the rigid straight tube 412 and the horizontal plane will further decrease, thereby limiting the flow rate of the indicator and the regulator at the rigid straight tube 412, so that the indicator and the regulator drip more slowly and are easier to control when they are close to the preset dripping amount; while the rigid straight tube 412 moves, the first slider 404 and the second slider 407 will both rise upward following the rigid straight tube 412, so that the distance between the rigid straight tubes 412 is shortened; the drip spring 403 is used to delay the upward sliding of the first slider 404, so that the second slider 407 slides upward before the first slider 404, so that the rigid straight tube 412 at the bottom has a higher rate of dripping. First, reduce the angle; when the sample volume of the sample liquid reaches the preset value, the suspension ball 420 stops rising, and then the control panel 103 controls the electric push rod on the electric card plate 405 to drive the electric card plate 405 to insert into the drip card slot 406, thereby realizing the locking function of the control bracket 413, and at the same time, the control panel 103 controls the water pump in the drip box 402 to stop working to prevent the indicator and the adjuster from falling; in the process of the sample liquid flowing into the reaction component 410, the sample liquid will pass through the reaction channel 423 on the partition plate 421, and the spiral blade 424 in the reaction channel 423 will cause turbulence inside the sample liquid, thereby promoting the mixing of the indicator, the adjuster and the sample liquid;When the indicator, the adjusting agent and the sample liquid are completely reacted, the conversion rod 409 is manually pulled to the right to connect the observation box 408 with the reaction assembly 410, and then the water pump on the second standard cylinder 505 draws the reacted sample liquid into the second standard cylinder 505. At this time, the ray emitter 502 emits a light beam to the standard liquid in the first standard cylinder 504 and the reacted sample liquid in the second standard cylinder 505, and then the light beam is projected onto the absorbance detector on the surface of the comparison base 506 to realize absorbance detection, thereby realizing the analysis and monitoring of the concentration of calcium, magnesium, strontium and barium ions; when the liquid level is driven by the suspension ball 420 to rise to the limit position by the limit bracket 422 and the first screw 414, the control bracket 413 will also drive the electric card plate 405 to lift to the limit position. At this time, the upper end of the electric card plate 405 will lift the comparison bracket 501 upward for a short distance, so that the card plate 503 is out of contact with the first standard cylinder 504, thereby facilitating the replacement of the first standard cylinder 504. ;
