Description

Technical Field

[0001] The invention relates to the technical field of sampling equipment, in particular to a chromogenic pool gas-liquid mixing pool detection sampling device. Background Art

[0002] A colorimetric tank usually refers to a device that produces color changes through a chemical reaction or physical process, while a gas-liquid mixing tank is a device specially designed to promote full contact and interaction between gas and liquid. Colorimetric tanks and gas-liquid mixing tanks are commonly used in industries such as sewage treatment, chemical engineering, and food processing.

[0003] Sampling is involved in the process of using the chromogenic cell and the gas-liquid mixing cell to carry out the corresponding preparation. Sampling is a key step to ensure accurate and representative data. The correct sampling method can help evaluate the gas-liquid mixing effect, monitor the progress of the chromogenic reaction, and verify the overall performance of the system.

[0004] When sampling the chromogenic pool and the gas-liquid mixing pool, different sampling devices need to be used for sampling. During the sampling process, multiple samplings are generally required. Each sampling requires manual placement of the sampling device in the chromogenic pool or the gas-liquid mixing pool. The overall sampling steps are cumbersome and labor-intensive, and the sampling efficiency needs to be improved. Moreover, when samples are subsequently extracted from the sampling device, the gas contained in the sample in the gas-liquid mixing pool is easy to escape, resulting in inaccurate detection results and affecting the evaluation of the gas-liquid mixing effect.

[0017] Beneficial effects of the present invention: 1. The present invention performs sampling through the linkage cooperation of the mounting ring, the lifting mechanism, the limit assembly, the sampling bottle and the driving assembly. The lifting mechanism is used to drive the mounting ring and the sampling bottle to move downward into the color development pool or the gas-liquid mixing pool. The limit assembly limits the descending depth of the sampling bottle. When the sampling bottle descends to the sampling depth, the limit assembly is used to drive the driving assembly to rotate the bottle cap to move the bottle cap upward.

When sampling, the bottle cap and the sealing plate are opened at the same time, which is convenient and quick to sample. When taking out the sample in the bottle, the bottle cap can be opened alone while the sealing plate remains sealed to avoid gas leakage in the sample. The sample can be extracted for testing only after the detection head matched with the baffle ring is inserted into the baffle ring and the sealing plate is pushed downward, thereby ensuring the accuracy of the detection. The device can sample the liquid in the chromogenic pool as well as the gas-liquid mixture in the gas-liquid mixing pool, and has high applicability.

[0019] 3. The present invention provides a plurality of sampling mechanisms, and the lower baffle in each sampling mechanism can be set to different heights, so that the lower baffle can limit the sampling height of the sampling bottle to different degrees, thereby facilitating sampling at different depths at the same time, and sampling at different depths can be performed in both the horizontal and vertical directions of the color development pool or the gas-liquid mixing pool, thereby improving the sampling efficiency and the diversity of the detection data.

[0034] See also Figure 2 and Figure 3, the fixed-angle rotation assembly 23 includes a stepping motor 231 fixedly installed at the center of the top of the housing 21. The bottom of the output shaft of the stepping motor 231 is fixedly connected to a shaft rod 232. The bottom end of the shaft rod 232 rotatably penetrates into the interior of the housing 21 and is fixedly connected to the turntable 22 coaxially.

[0035] Please refer to Figure 2-Figure 5 , when a sampling bottle 27 finishes sampling, the stepping motor 231 drives the shaft rod 232 to rotate counterclockwise by 120°, and then the shaft rod 232 drives the turntable 22 to rotate counterclockwise by 120°, so that another sampling bottle 27 to be sampled moves to the left, and the sampled sampling bottle 27 moves to the right below the housing 21, facilitating subsequent sampling.

[0036] Please refer to Figure 2 , Figure 4 , Figure 5 , the lifting mechanism 25 includes a plurality of groups of movable rods 251 that are circumferentially evenly and vertically slidably installed on the turntable 22. The number of movable rods 251 in the same group is two, and the bottom ends are fixedly connected to the top of the corresponding mounting ring 24. The two movable rods 251 in the same group are symmetrically distributed with respect to the corresponding mounting ring 24. The top ends of the movable rods 251 penetrate above the turntable 22 and are fixedly connected to a U-shaped member 252. The two U-shaped members 252 are distributed with their openings facing each other. A lifting plate 253 that cooperates with the U-shaped member 252 is vertically movably installed inside the housing 21, and a lifting member 254 for driving the lifting plate 253 to move up and down is installed on the housing 21.

[0037] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the lifting member 254 includes a vertical sliding frame 2541 fixedly connected to the lower part of the inner top wall of the housing 21. The bottom of the vertical sliding frame 2541 slidably abuts against the top of the turntable 22. A lead screw 2542 is rotatably installed inside the vertical sliding frame 2541.

[0038] When sampling is to be carried out, first place the moving bracket 1 on the coloring pool or the gas-liquid mixing pool. Drive the lead screw 2542 to rotate through the driving motor 2543, then the lead screw 2542 drives the lifting plate 253 to move downward, then the lifting plate 253 drives a pair of U-shaped members 252 and movable rods 251 on the left side to move downward, and then the movable rods 251 push the mounting ring 24 to move downward, submerging the sampling bottle 27 into the pool for sampling.

[0039] Please refer to Figure 2 and Figure 5 The limit assembly 26 includes a lower baffle 261 arranged below the mounting ring 24, and an adjusting component 262 for adjusting the upper and lower limit of the lower baffle 261 is installed on the turntable 22. The adjusting component 262 includes a limit rod 2621 slidably installed on the turntable 22, and the limit rod 2621 is located on the outer side of the corresponding mounting ring 24. The bottom end of the limit rod 2621 is fixedly connected to the corresponding lower baffle 261, and the top of the limit rod 2621 is fixedly connected to an upper baffle 2622 located above the turntable 22. The upper baffle 2622 is slidably installed on the corresponding movable rod 251 up and down. A plurality of jacks equidistantly distributed up and down are opened on the limit rod 2621, and a fixing sleeve 2623 slidingly sleeved on the outside of the limit rod 2621 is fixedly connected to the bottom of the turntable 22, and a limit bolt 2624 engaged with the jack is threadedly installed on the outer ring wall of the fixing sleeve 2623.

[0040] When the height of the lower baffle 261 is to be adjusted, the limit bolt 2624 is first loosened to separate it from the socket, and then the limit rod 2621 is moved up and down to adjust the height of the lower baffle 261 so that the lower baffle 261 can limit the mounting ring 24 and the sampling bottle 27 from descending to different depths for sampling. After the height of the lower baffle 261 is adjusted, the corresponding socket on the limit rod 2621 is aligned with the limit bolt 2624, and then the limit bolt 2624 is tightened to insert the limit bolt 2624 into the socket to fix the limit rod 2621 to prevent the limit rod 2621 from moving up and down.

[0041] See also Figure 6 , Figure 8 and Fig. 9 The top of the inner ring wall of the bottle mouth 2711 is integrally formed with a retaining ring and a rubber layer is arranged on the outside of the retaining ring. The sealing plate 274 is a stepped truncated cone-shaped structure. The upper stepped platform of the sealing plate 274 is plugged into the retaining ring, and the top of the lower stepped platform is in conflict with the bottom of the retaining ring. Side through grooves 2741 are provided on the front and rear sides of the lower stepped platform of the sealing plate 274. One end of the pull rope 276 is fixedly connected to the bottom of the sealing plate 274, and the other end is movably penetrated through the support member 273 and the bottle body 271 in turn and is fixedly connected with a connecting bolt 2762 after penetrating to the outside of the bottle body 271. A sliding ring 2722 is rotatably installed at the bottom of the bottle cap 272, and the connecting bolt 2762 is threadedly connected to the bottom of the sliding ring 2722.

A sealing block 2761 is fixedly connected to the pull rope 276, and the sealing block 2761 is slidably installed in the corresponding active cavity 2732 up and down.

[0042] The return spring 275 pushes the sealing plate 274 upward to be plugged into the retaining ring, so as to seal the bottle mouth 2711 internally. The bottle cap 272 threadedly connected to the bottle mouth 2711 externally can seal the bottle mouth 2711 externally to prevent the liquid sample or gas-liquid mixed sample in the bottle body 271 from leaking. Before sampling, the connecting bolt 2762 is threadedly connected to the slip ring 2722. When sampling, the bottle cap 272 is unscrewed upward, and at the same time, the bottle cap 272 pulls one end of the pull rope 276 upward through the connecting bolt 2762, and then the pull rope 276 can drive the sealing plate 274 to move downward, so that the inner and outer seals are opened at the same time. After sampling is completed, The bottle cap 272 and the sealing plate 274 are reset; but when the extracted sample needs to be taken out, the connecting bolt 2762 is loosened from the slip ring 2722, so that when the bottle cap 272 is opened, the sealing plate 274 will not be opened at the same time, and the sample can be extracted only after the existing detection head or pipette is inserted into the retaining ring and the sealing plate 274 is pushed downward. After the detection head or pipette is inserted into the bottle mouth 2711, the bottle body 271 is tilted or inverted to allow the detection head or pipette to better extract the sample. The detection head or pipette is plugged together with the retaining ring to prevent other substances in the gas-liquid mixed sample from diffusing to the outside, thereby ensuring the accuracy of the detection.

[0043] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 The fixing assembly 28 includes a plurality of groups of fixing plates 281 uniformly distributed circumferentially on the inner side of the mounting ring 24. The number of the fixing plates 281 in the same group is two and they are distributed up and down. The inner circumference of the mounting ring 24 is uniformly installed with a plurality of moving parts 282 for driving the corresponding fixing plates 281 to clamp inward. The bottom of the mounting ring 24 is rotatably installed with a plurality of bottom support plates 283 uniformly distributed circumferentially. The mounting ring 24 is installed with a fixing part 284 for limiting the moving part 282.

[0044] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 The movable component 282 includes a movable column 2821 which is slidably installed inside the mounting ring 24 along its radial direction, and one end of the movable column 2821 close to the center of the mounting ring 24 is fixedly connected to the lower fixed plate 281, and the top of the movable column 2821 is fixedly connected to the upper fixed plate 281 through a vertical rod, and a baffle 2822 is fixedly connected to the movable column 2821, and a return spring 2823 arranged on the outside of the movable column 2821 is fixedly connected between the side of the baffle 2822 close to the center of the mounting ring 24 and the inner wall of the mounting ring 24, and a limiting hole 2824 is opened on the top of the movable column 2821 between the fixed plate 281 and the return spring 2823, and the top of the bottom support plate 283 blocks the outer side of the end of the movable column 2821 away from the center of the mounting ring 24.

[0045] See also Figure 2 , Figure 5 , Figure 6 and Figure 7 The fixing component 284 includes a connecting ring 2841 movably installed up and down on the top of the mounting ring 24, and the bottom of the connecting ring 2841 is fixedly connected with a plurality of tension springs 2842 evenly distributed in the circumferential direction, and the top of the mounting ring 24 is provided with a hole groove for installing the tension spring 2842, and the bottom of the connecting ring 2841 is fixedly connected with a fixing pin 2843 corresponding to the movable column 2821 one by one, and the bottom end of the fixing pin 2843 slides through the interior of the mounting ring 24 and then engages with the corresponding limiting hole 2824.

[0046] In the initial state, the return spring 2823 is in a compressed state. When the sampling bottle 27 is to be removed, the connecting ring 2841 is first moved upward, and the connecting ring 2841 is used to drive the fixing pin 2843 to move upward, so that the fixing pin 2843 is separated from the limiting hole 2824 and no longer restricts the movable column 2821. At this time, the tension spring 2842 is in a stretched state, and then the bottle body 271 is picked up and moved upward. At this time, the rebound force of the return spring 2823 is used to push the movable column 2821 to move away from the center of the mounting ring 24, so that the fixing plate 281 releases the clamping of the bottle body 271. At the same time, the movable column 2821 is used to push the top end of the bottom support plate 283 to rotate in a direction away from the center of the mounting ring 24, so that the bottom end of the bottom support plate 283 is deflected upward until the bottle body 271 is completely taken out of the mounting ring 24.

[0047] When a new sampling bottle 27 is to be placed, the bottle body 271 is aligned with the center of the mounting ring 24, and then the bottle body 271 is pushed downward, and the bottom end of the bottom support plate 283 is pushed downward by the bottle body 271. At this time, the top of the bottom support plate 283 pushes the movable column 2821 to move toward the center of the mounting ring 24, and then the movable column 2821 is used to push the fixing plate 281 to move toward the center of the mounting ring 24, so that the fixing plate 281 clamps the outer wall of the bottle body 271 until the bottom end of the bottle body 271 is free of The method continues to deflect downward, and the gravity of the sampling bottle 27 is used to achieve adaptive clamping. At this time, the movable column 2821 is just aligned with the fixing pin 2843, and then the connecting ring 2841 is loosened, and the resilience of the tension spring 2842 is used to drive the connecting ring 2841 and the fixing pin 2843 to move downward, so that the fixing pin 2843 is inserted into the inside of the limiting hole 2824 to lock the movable column 2821, so that the sampling bottle 27 can be quickly fixed, thereby improving the disassembly and assembly efficiency of the sampling bottle 27. At this time, the tension spring 2842 is in a naturally extended state.

The top of the bottle cap 272 is engaged with the driving wheel 292 through a fixedly connected toothed ring. The thickness of the driving wheel 292 is much greater than that of the toothed ring. Two movable brackets 293 are also slidably installed up and down on the movable rod 251 on the side far from the center of the turntable 22, and are distributed on the upper and lower sides of the fixing bracket 291. A driving rod 294 is rotatably connected between the two corresponding movable brackets 293 up and down. A spiral groove is formed on the outer part of the driving rod 294. The driving wheel 292 is sleeved on the outer part of the driving rod 294, and a convex block matched with the spiral groove is installed on the inner ring wall of the driving wheel 292. A third return spring 295 sleeved on the outer part of the driving rod 294 is fixedly connected between the bottom of the fixing bracket 291 and the lower movable bracket 293.

[0049] Please refer to Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9 , when the sampling bottle 27 moves downward to the height where sampling is required, the upper movable bracket 293 first contacts the lower baffle 261, and then as the movable rod 251 continues to move downward and drives the driving wheel 292 to move downward, the driving rod 294 moves upward relative to the driving wheel 292. The spiral groove on the outer part of the driving rod 294 and the convex block cooperate to drive the driving wheel 292 to rotate, and then the driving wheel 292 drives the bottle cap 272 to rotate, so that the bottle cap 272 is unscrewed upward relative to the bottle mouth 2711. When the upper baffle 2622 contacts the corresponding U-shaped part 252, the movable bracket 293 cannot move further, so that the driving rod 294 no longer drives the driving wheel 292 to rotate. The upper baffle 2622 limits the corresponding U-shaped part 252 to prevent the movable rod 251 from continuing to move downward, so that the bottle body 271 is positioned at the height where sampling is required.

[0050] At this time, the liquid inlet 2721 just moves to the top of the bottle mouth 2711, and the bottom of the bottle cap 272 is still threadedly connected to the bottle body 271. During the upward movement of the bottle cap 272, the bottle cap 272 drives the sealing plate 274 to move downward through the pull rope 276, so that the sealing plate 274 is separated from the retaining ring. At this time, the first return spring 275 will be compressed, and the external liquid flows into the bottle body 271 through the liquid inlet 2721, the side through groove 2741 and the communication port 2731 in sequence.

[0051] During the movement of the pull rope 276, the sealing block 2761 will move up and down along the communication port 2731, and the sealing block 2761 plays a sealing role to prevent the sample inside the bottle body 271 from overflowing out through the channel where the pull rope 276 moves.

[0052] After sampling is completed, the driving motor 2543 drives the lead screw 2542 to rotate in the opposite direction, so that the lifting plate 253 drives the corresponding shaped part 252 and the movable rod 251 to move upward, and the rebound force of the reset spring three 295 is used to drive the driving rod 294 to move downward relatively, and then the driving rod 294 drives the driving wheel 292 to rotate in the opposite direction, and then the driving wheel 292 drives the bottle cap 272 to rotate in the opposite direction, so that the bottle cap 272 is tightened on the bottle mouth 2711, and at the same time, the rebound force of the reset spring one 275 is used to drive the sealing plate 274 to move upward, so that the sealing plate 274 re-closes the retaining ring.

[0053] See also Figure 2 and Figure 3 An outer support ring 211 is fixedly connected to the inner ring wall of the shell 21, and an inner support ring 212 is arranged on the inner side of the outer support ring 211. The top of the inner support ring 212 is fixedly connected to the inner top wall of the shell 21 by a pipe sleeve sleeved on the outside of the shaft rod 232. A notch 213 for the C-shaped piece 252 to pass through is opened on the outer support ring 211 and the inner support ring 212. The notches 213 on the outer support ring 211 and the inner support ring 212 are opposite to each other, and the inner support ring 212 and the outer support ring 211 are supported on the bottom of the corresponding C-shaped piece 252.

[0054] A pair of C-shaped parts 252 on the left side are aligned with the notch 213, and the lifting plate 253 is inserted between the two C-shaped parts 252 on the left side. Among the other two pairs of C-shaped parts 252, the C-shaped parts 252 close to the center of the shell 21 are supported on the inner support ring 212, and the C-shaped parts 252 away from the center of the shell 21 are supported on the outer support ring 211. The outer support ring 211 and the inner support ring 212 are used to support the C-shaped parts 252.

[0055] See also Figure 1-Figure 9During the first sampling, the mobile bracket 1 is located at the right end of the color pool or the gas-liquid mixing pool, and the three lower baffles 261 in each sampling mechanism 2 are respectively at three different restricted heights of high, medium and low, so that the three sampling bottles 27 in the same sampling mechanism 2 can respectively perform sampling at three different depths of high, medium and low. At the same time, there is a height difference between the lower baffles 261 located on the left side of the three sampling mechanisms 2. In this way, when sampling is performed on the right half of the color pool or the gas-liquid mixing pool, sampling at three different depths of high, medium and low can be completed simultaneously in the front-to-back direction. Sampling is completed at this location. Finally, the movable bracket 1 is moved to the middle of the chromogenic pool or the gas-liquid mixing pool, and then the fixed-angle rotating component 23 is controlled at the same time to drive the turntable 22 to rotate 120° clockwise to replace the sampling bottle 27. At this time, there is still a height difference between the lower baffles 261 located on the left side of the three sampling mechanisms 2, and the sampling bottles 27 that are sampled successively on the same sampling mechanism 2 have different descending heights. Through the above operation, it is ensured that sampling of different depths can be completed in the front and rear directions and the left and right directions of the chromogenic pool or the gas-liquid mixing pool, the sampling range is wider, and the detection result is more accurate.
