Description

Technical Field

[0001] The invention relates to the technical field of ethylene oxide analysis, in particular to an ethylene oxide trace water analyzer. Background Art

[0002] Ethylene oxide is an organic compound that is used in many fields. For example, it is a highly effective disinfectant and sterilizer, commonly used in the sterilization of medical devices, medicines, cosmetics, etc. Ethylene oxide can also be used as an insecticide to control pests. Ethylene oxide is a toxic and harmful substance that poses potential risks to human health and environmental safety. Its content can be accurately measured by an analyzer to ensure a safe level in the working environment.

[0003] In the ethylene oxide analysis process, different sample media need to be analyzed and measured, and different wavelengths of light are required for this purpose. However, due to design reasons, some existing ethylene oxide analyzers usually require adjusters to rotate the knob slowly, which makes it inconvenient to adjust the filter. Since the adjusters rotate manually, they need to be careful not to use excessive force to cause damage. At the same time, the adjustment is prone to poor adjustment accuracy, resulting in the inability to flexibly adjust the filter. The inconvenient adjustment of the filter height will limit the screening of light of different wavelengths, affecting the accuracy and flexibility of spectral analysis. Secondly, for samples of different sizes or shapes, the inability to adjust the filter height will lead to adaptability problems. At the same time, manual rotation will result in poor accuracy, so that the filter will allow light of other wavelengths to enter, generating interference signals, affecting the quality of the data, causing the spectrum shape to be distorted, making spectral analysis difficult or meaningless.

[0004] At the same time, when testing liquid media, some samples contain impurities such as suspended matter, and are affected by dust and impurities in the surrounding environment, which easily forms dirt on the surface of the measuring cell. However, since most of the existing methods are manually wiped with isopropyl alcohol, the operation is inconvenient and isopropyl alcohol has certain irritating gases, making manual operation risky.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When adjusting the optical filter, firstly, the control panel is used to drive the motor to operate, so that the driving motor transmission threaded rod drives the mounting plate to stably reciprocate up and down. During the movement of the mounting plate, the first supporting shell and the second supporting shell can be driven to support the movement of the optical filter. In the process of the mounting plate being driven, the mounting plate is limited by the working slot, thereby realizing linear movement, so that the filter can be flexibly and accurately adjusted in height, and can be automatically adjusted according to the needs of use, and the required wavelength of light can be selected more accurately, improving the accuracy and specificity of measurement, reducing manual participation in adjusting the height, thereby ensuring the accuracy of adjustment, and at the same time, avoiding the participation of analysts in rotating the knob for adjustment, and the automatic and flexible adjustment improves the overall work efficiency, thereby realizing the convenience of quickly adjusting the height of the filter, and screening and controlling light of different colors;

[0018] The limit block is provided to slide in the limit groove, so that when the first supporting shell and the second supporting shell are rotated, the limit block can cooperate with the limit groove. During the rotation of the first supporting shell and the second supporting shell, the limit block slides in the limit groove, so that after the mounting plate drives the filter sheet to move to the bottom up and down, the limit block can slide in the limit groove to adapt to the rotation positions of the first supporting shell and the second supporting shell with different rotation angles, thereby achieving the effect of transmission adjustment height and support, so that after the first supporting shell and the second supporting shell are rotated at an angle, the mounting plate can still slide in the limit groove to support the first supporting shell and the second supporting shell through the limit block to prevent dislocation, and improve the stability and adaptability, which is beneficial to improving the rotation stability of the first supporting shell and the second supporting shell, and is convenient for replacing the filter sheet, thereby achieving the effect of support rotation adaptation;

[0019] 3. The first gear is meshed with the second gear, so that the first gear is driven by the transmission meshing transmission arc rack to move, so that the movement of the arc rack can drive the position of the first support shell and the second support shell to rotate, and the arc rack transmission rotation force rotates the second support shell to the corresponding position of the guide groove, and because the guide groove and the second support shell are on the same horizontal line, the second support shell can be unfolded by the pushing force of the spring, and at this time, it is convenient for the analyst to hold the second support shell and apply force to unfold it, so as to take out and replace the filter, and avoid the situation that after the service life of the filter is reached, due to the automatic adjustment of the upper and lower positions of the filter, it is inconvenient to cooperate with the replacement of the filter, and the effect of disassembly after turning can be achieved, which is conducive to ensuring the steering stability and accuracy of the filter when it needs to be replaced;

[0020] 4. The cleaning sponge is set so that the surface window of the sensor measuring pool can be wiped by the cleaning sponge when the fixed plate moves, and as the fixed plate moves, the water outlet expands to discharge the isopropyl alcohol, and the isopropyl alcohol will drip onto the surface of the cleaning sponge, which is convenient for the cleaning sponge to be soaked in order to wipe the surface window of the sensor measuring pool, reducing manual wiping by analysts. Then, the cleaning sponge moves up and down driven by the fixed plate to complete the wiping of the surface window of the sensor measuring pool, thereby improving the cleaning effect, reducing the participation of analysts in cleaning, ensuring the accuracy of measurement after wiping, and avoiding manual wiping. Since isopropyl alcohol has a pungent gas, analysts endure the pungent gas when wiping, which is conducive to the adaptive cleaning of the main window of the sensor measuring pool and reducing dirt contamination of the liquid medium.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 8 , is an embodiment provided by the present invention: an ethylene oxide trace water analyzer, comprising a controller body 1 and a sensor measuring cell body 2, a detection end pipe body 3, an optical cavity 4, a cable 5 and a filter 6, wherein the sensor measuring cell body 2 is arranged outside the controller body 1, the detection end pipe body 3 is movably installed on the surface of the sensor measuring cell body 2, the optical cavity 4 is movably connected to the surface of the sensor measuring cell body 2 and is located below the detection end pipe body 3, one end of the cable 5 is fixedly connected to a port where the detection end pipe body 3 and the optical cavity 4 are away from each other, the other ends of the two cables 5 away from the detection end pipe body 3 and the optical cavity 4 are connected to the controller body 1, the filter 6 is installed in the optical cavity 4, an adjustment component for improving flexibility and calibration is arranged inside the optical cavity 4, and a replacement component for improving equipment maintainability and increasing flexibility is arranged on the lower surface of the adjustment component.

[0037] The adjustment component includes a first supporting shell 7, which is sleeved on the surface of the filter 6. A second supporting shell 8 is arranged on one side of the surface of the first supporting shell 7. The first supporting shell 7 and the second supporting shell 8 are symmetrically sleeved on the surface of the filter 6. An operating groove 9 is provided on the inner wall of the optical cavity 4. A threaded rod 10 is rotatably connected in the operating groove 9. The bottom end of the threaded rod 10 passes through the bottom surface of the optical cavity 4. A driving motor 11 is fixedly connected to the bottom surface of the optical cavity 4. The output shaft of the driving motor 11 is fixedly connected to the threaded rod 10. A mounting plate 12 is threadedly connected to the surface of the threaded rod 10. The mounting plate 12 is tightly fitted with the operating groove 9. A limiting groove 13 is provided on the surface of the first supporting shell 7. The limiting groove 13 is in a semi-arc shape. A limiting block 14 is slidably connected in the limiting groove 13. The side of the limiting block 14 away from the limiting groove 13 is fixedly connected to the mounting plate 12.

[0038] Specifically, when the position of the filter 6 needs to be adjusted to obtain a more accurate measurement result, the drive motor 11 can be connected to operate through the external control panel, so that the drive motor 11 is started to drive the threaded rod 10 to rotate. At this time, the threaded rod 10 can thread the mounting plate 12 when rotating, and because the mounting plate 12 and the surface of the working groove 9 are in a tightly fitted state, the mounting plate 12 can be limited by the working groove 9 when being pushed by the threaded transmission of the threaded rod 10, thereby realizing linear movement. At this time, the mounting plate 12 can drive the first support shell 7 and the second support shell 8 to move upward when moving upward, so that the first support shell 7 and the second support shell 8 can be moved upward. The support shell 7 and the second support shell 8 can push the filter 6 to move upward so that the filter 6 can adapt to the required light of different wavelengths, thereby improving the accuracy and specificity of the measurement. By adjusting the height of the filter 6, the required wavelength of light can be selected more accurately, thereby improving the accuracy and specificity of the measurement. For light of different colors, adjusting the height of the filter 6 can change the transmittance of the light, thereby realizing the screening and control of light of different colors. In addition, the threaded rod 10, the drive motor 11, and the mounting plate 12 can achieve the effect of facilitating the adjustment of the height of the filter 6, thereby facilitating the debugging of the filter 6 for light.

[0039] The replacement component includes an arcuate rack 15, which is fixedly connected to the lower surface of the first supporting shell 7, and the outer surface of the arcuate rack 15 is meshed with a first gear 16, the first gear 16 is rotatably connected to the optical cavity 4, and the side of the first gear 16 away from the arcuate rack 15 is meshed with a second gear 17, and the second gear 17 is rotatably connected to the working groove 9, the inner surface of the arcuate rack 15 is fixedly connected to two symmetrically arranged mounting blocks 18, and the bottom surface of the second supporting shell 8 is fixedly connected to two symmetrically arranged sliding blocks 19, the surface of the mounting block 18 is fixedly connected to a guide rod 20, and the side where the mounting block 18 and the sliding block 19 are close to each other is fixedly connected to a spring 21, and the spring 21 is sleeved on the surface of the guide rod 20, the surface of the optical cavity 4 is penetrated by a guide groove 22, and the surface of the sensor measuring cell body 2 is provided with a cleaning component for improving measurement accuracy and extending service life.

[0040] Specifically, during the process of detecting the material medium by the controller body 1, the sensor measuring pool body 2, and the detection end pipe body 3, if the service life of the filter 6 is poor and the performance accuracy is reduced over time and the filter 6 needs to be replaced, the drive motor 11 can be started through the control panel first. At this time, the drive motor 11 can drive the threaded rod 10 to rotate in the opposite direction, so that the threaded rod 10 can thread the mounting plate 12 to move downward. As the mounting plate 12 moves downward to the bottom surface, the arc-shaped rack 15 can be engaged with the surface of the first gear 16 to present an engaged state. At this time, after the first gear 16 is engaged with the arc-shaped rack 15, the meshing transmission of the second gear 17 can make the first gear 16 drive the arc-shaped rack 15 to drive the first support shell 7 and the second support shell 8 to rotate. As the first support shell 7 and the second support shell 8 rotate and move, the second support shell 8 can be flipped to the same horizontal line as the guide groove 22. At this time, the second support shell 8 is on the same horizontal line as the guide groove 22. At this time, the second support shell 8 is no longer subject to the force applied by the optical cavity 4, and can be offset by the spring 21. The elastic force pushes the sliding block 19, so that the sliding block 19 moves on the surface of the guide rod 20 away from the mounting block 18. At this time, the sliding block 19 can drive the second support shell 8 to expand away from the first support shell 7. At the same time, the second support shell 8 can be gradually moved out of the guide slot 22 under the elastic pushing force of the spring 21. At this time, the inspection personnel can hold the second support shell 8 and pull it from the protruding part of the guide slot 22, so that the sliding block 19 can fit with the end of the guide rod 20 away from the mounting block 18. Then, after the second support shell 8 is expanded, the surface of the filter 6 can be tilted by holding the filter 6. At this time, the filter 6 can be taken out and replaced from the first support shell 7 and the second support shell 8, so that different experiments or applications require filters 6 with different characteristics by replacing the filter 6. Convenient replacement can meet various needs, and timely replacement can ensure accuracy. In addition, the arc rack 15, the first gear 16, and the second gear 17 are provided. Through the transmission of the second gear 17 and the threaded rod 10, the effect of convenient replacement of the filter 6 can be achieved, which is conducive to ensuring the accuracy of the filter 6.

[0041] The cleaning assembly includes a placement rack 23, which is symmetrically arranged on one side of the surface of the sensor measuring pool body 2. The upper surfaces of the two placement racks 23 are fixedly connected with hollow plates 24, and the upper surfaces of the hollow plates 24 are fixedly connected with a storage box 25. The upper surface of the storage box 25 is fixedly connected with a driving cylinder 26. The output end of the driving cylinder 26 passes through the surface of the storage box 25. The bottom surface of the storage box 25 is penetrated by two symmetrically arranged water outlet grooves 27. A baffle 28 is arranged in the water outlet groove 27. The surface of the baffle 28 is fixedly connected with a rotating rod 29. The rotating rod 29 is rotatably connected to the water outlet groove 27. Both ends of the surface of the rotating rod 29 are sleeved A torsion spring 30 is provided, and the two ends of the torsion spring 30 are fixedly connected to the baffle 28 and the water outlet trough 27 respectively. A pressure plate 31 is fixedly connected to the output end surface of the driving cylinder 26, and two symmetrically arranged pressure blocks 32 are fixedly connected to the lower surface of the pressure plate 31. A push plate 33 is provided in the hollow plate 24, and the push plate 33 is fixedly connected to the bottom end of the output end of the driving cylinder 26. Water receiving plates 34 are fixedly connected on both sides of the push plate 33. A groove 35 is provided on the surface of the water receiving plate 34 away from the push plate 33. A fixing plate 36 is fixedly connected to the surface of the water receiving plate 34, and a cleaning sponge 37 is fixedly connected to the sides of the two fixing plates 36 close to each other.

[0042] Specifically, when the sensor measuring pool body 2 needs to detect the installation of the liquid medium, it is first necessary to wipe the window of the sensor measuring pool body 2. At this time, it can be connected to the driving cylinder 26 through the external control panel, and then the driving cylinder 26 is started through the control panel to push the pressure plate 31 downward. At this time, the pressure plate 31 can gradually push the surface of the baffle 28 to flip through the pressure block 32 during the downward movement. As one side of the baffle 28 flips and cancels the fit with the bottom surface of the storage box 25, the baffle 28 can cancel the closed state at the water outlet 27. Then the isopropyl alcohol placed in the storage box 25 can be discharged through the water outlet 27. At this time, the isopropyl alcohol can drip into the water receiving plate 34 for storage. When the isopropyl alcohol in the water receiving plate 34 is stored to a certain level, the isopropyl alcohol in the water receiving plate 34 can penetrate the cleaning sponge 37 through the groove 35. At the same time, the output end of the driving cylinder 26 can make the push plate 33 move downward in the process of pushing the pressure plate 31 downward. The isopropyl alcohol and the push plate 33 move downward at the same time. As the push plate 33 moves downward, the fixed plate 36 and the cleaning sponge 37 can be driven to move downward. At this time, the water outlet 27 soaked in isopropyl alcohol can wipe the window on the surface of the sensor measuring cell body 2 during the downward movement. After the wiping is completed, the fixed plate 36 and the cleaning sponge 37 move up to complete the cleaning operation, and then the isopropyl alcohol at the window of the sensor measuring cell body 2 can be waited for to dry, so as to facilitate the cleaning of the surface window of the sensor measuring cell body 2 and ensure the accuracy of the measurement. Dirt or impurities can affect the measurement accuracy of the sensor. Regular cleaning can keep it in good working condition. Secondly, cleaning can extend the service life of the sensor, avoid the accumulation of dirt and pollutants, and reduce the risk of failure and damage. In addition, the driving cylinder 26, the water outlet 27, and the cleaning sponge 37 can realize the wiping and cleaning of the window of the sensor measuring cell body 2, which is conducive to cleaning the window of the sensor measuring cell body 2 and reducing the situation where dirt contaminates the liquid medium.

[0043] The first supporting shell 7 and the second supporting shell 8 form a ring shape.

[0044] Specifically, the first supporting shell 7 and the second supporting shell 8 are arranged to form a ring shape, so that the first supporting shell 7 and the second supporting shell 8 are better fitted at the arc surface of the filter 6, thereby reducing the shaking of the filter 6 and improving the stability.

[0045] Rubber blocks are fixedly connected to the upper surfaces of the inner walls of the first supporting shell 7 and the second supporting shell 8 , and the rubber blocks are in contact with the surface of the filter 6 .

[0046] Specifically, by providing the first supporting shell 7 and the second supporting shell 8 with a rubber stopper fixedly connected thereto, the filter 6 can be blocked by the rubber stopper when installed between the first supporting shell 7 and the second supporting shell 8, thereby reducing shaking.

[0047] The guide rod 20 penetrates the surface of the sliding block 19 , and the contact surface between the sliding block 19 and the guide rod 20 is smooth and fitted.

[0048] Specifically, by setting the guide rod 20 to penetrate the surface of the sliding block 19, when the elastic force of the spring 21 pushes the guide rod 20 to move, the guide rod 20 can be guided by the sliding block 19, reducing the deviation of the guide rod 20 and improving the deployment stability.

[0049] The pressure block 32 is located above the water outlet trough 27 .

[0050] Specifically, by setting the pressure block 32 above the water outlet trough 27, the pressure block 32 can easily push the baffle 28 to expand when it is pushed by the pressure plate 31 and the driving cylinder 26, thereby preventing the pressure plate 31 from abutting against the baffle 28 and making it difficult to push.

[0051] The lead-out groove 22 is in a semi-arc shape.

[0052] Specifically, by setting the lead-out slot 22 to be in a semi-arc shape, the lead-out slot 22 can be better adapted to the unfolding of the second support shell 8, so as to facilitate the replacement of the optical filter 6, improve the replacement efficiency, and prevent the interference.

[0053] The fixing plate 36 has an L shape.

[0054] Specifically, by setting the fixing plate 36 to be L-shaped, the cleaning sponge 37 can be easily driven when the fixing plate 36 moves to improve the wiping cleaning effect.

[0055] The above implementation works as follows:

[0056] The initialization steps are as follows:

[0057] The staff connects the controller body 1 with the sensor measuring cell body 2 , the detection end pipe body 3 , the optical cavity 4 , and the cable 5 , and then places them on the surface of the workbench, and then starts to adjust the height of the filter 6 .

[0058] The working steps are as follows:

[0059] like Figure 1-Figure 6As shown, when adjusting the height of the optical filter 6, the staff starts the driving motor 11 to rotate the threaded rod 10. At this time, the threaded rod 10 can thread the mounting plate 12 when rotating, and because the mounting plate 12 and the surface of the working groove 9 are in a tightly fitted state, the mounting plate 12 can be limited by the working groove 9 when being pushed by the threaded transmission of the threaded rod 10, thereby realizing linear movement. At this time, the mounting plate 12 can drive the first supporting shell 7 and the second supporting shell 8 to move upward when moving upward, so that the first supporting shell 7 and the second supporting shell 8 can push the optical filter 6 to move upward, so that the optical filter 6 can adapt to the light of different wavelengths as required, thereby improving the accuracy and specificity of the measurement;

[0060] During the process of detecting the material medium by the controller body 1, the sensor measuring pool body 2, and the detection end pipe body 3, as time goes by, the service life of the filter 6 is poor and the performance accuracy is reduced. At this time, the filter 6 needs to be replaced;

[0061] While the filter is being replaced, the staff starts the drive motor 11 and adjusts it to a reverse state. The drive motor 11 can drive the threaded rod 10 to rotate in the opposite direction, so that the threaded rod 10 can threadably drive the mounting plate 12 to move downward. As the mounting plate 12 moves downward to the bottom surface, the arc-shaped rack 15 can be engaged with the surface of the first gear 16 to present an engaged state. At this time, after the first gear 16 is engaged with the arc-shaped rack 15, the meshing transmission of the second gear 17 can make the first gear 16 drive the arc-shaped rack 15 to drive the first support shell 7 and the second support shell 8 to rotate. As the first support shell 7 and the second support shell 8 rotate and move, the second support shell 8 can be flipped over to the same horizontal line as the lead-out slot 22. At this time, the second support shell 8 and the lead-out slot 22 are on the same horizontal line. At this time, the second support shell 8 is no longer resisted by the force applied by the optical cavity 4, and the sliding block 19 can be pushed by the elastic force of the spring 21, so that the sliding block 19 moves on the surface of the guide rod 20 away from the mounting block 18. At this time, the sliding block 19 can drive the second support shell 8 to expand away from the first support shell 7. At the same time, the second support shell 8 can be gradually moved out of the lead-out slot 22 by the elastic force of the spring 21. At this time, the inspection personnel can hold the second support shell 8 and apply force to pull the protruding part of the lead-out slot 22, so that the sliding block 19 can fit with the end of the guide rod 20 away from the mounting block 18. Then, after the second support shell 8 is expanded, the surface of the filter 6 can be held by hand to tilt, and the filter 6 can be taken out from the first support shell 7 and the second support shell 8 for replacement;

[0062] like Figure 7-Figure 8 It is shown that when the sensor measuring pool body 2 needs to be installed to detect the liquid medium, the window of the sensor measuring pool body 2 needs to be wiped first;

[0063] The staff connects the external control panel to the driving cylinder 26, and then the control panel starts the driving cylinder 26 to push the pressure plate 31 downward. At this time, the pressure plate 31 can gradually push the surface of the baffle 28 to flip through the pressure block 32 during the downward movement. As one side of the second support shell 8 flips and cancels the fit with the bottom surface of the storage box 25, the baffle 28 can cancel the closed state at the water outlet trough 27. Then the isopropyl alcohol placed in the storage box 25 can be discharged through the water outlet trough 27. At this time, the isopropyl alcohol can drip into the water receiving plate 34 for storage. When the isopropyl alcohol in the water receiving plate 34 is stored to a certain level, the isopropyl alcohol in the water receiving plate 34 can penetrate the cleaning sponge 37 through the groove 35, and the driving The output end of the cylinder 26 can make the push plate 33 move downward in the process of pushing the pressure plate 31 downward, and the water outlet trough 27 drips isopropyl alcohol and the push plate 33 moves downward at the same time. As the push plate 33 moves downward, the fixed plate 36 and the cleaning sponge 37 can be driven to move downward. At this time, the water outlet trough 27 soaked in isopropyl alcohol can wipe the window on the surface of the sensor measuring cell body 2 during the downward movement. After the wiping is completed, the fixed plate 36 and the cleaning sponge 37 move up to complete the cleaning operation, and then the isopropyl alcohol at the window of the sensor measuring cell body 2 can be waited for to dry, thereby achieving the benefit of convenient cleaning, reducing the irritating gas of isopropyl alcohol inhaled by the staff, and conveniently detecting the medium during the installation of the liquid medium, in which impurities and dust at the window affect the medium detection.
