Description

Technical Field

[0001] This invention relates to the field of organic matter detection equipment technology, and in particular to a fully automated low-concentration organic matter production line. Background Technology

[0002] Most existing test samples (such as soil, food, and water) contain low concentrations of organic compounds such as dioxins, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). However, the pretreatment for detecting these low concentrations of organic compounds is quite cumbersome. One step requires pre-acidification of the sample. Traditional methods usually require manual weighing, solution preparation, and shaking of the solution, resulting in low efficiency, complex manual operation, and high cost. Furthermore, some sample processing can produce toxic gases, which may endanger human health to some extent.

[0003] Currently, there are some production lines that can detect low concentration organic compounds. However, some processes still require manual operation. Manual operation is not only inefficient and troublesome, but also has high labor costs and is not environmentally friendly, making it difficult to meet the needs of remotely controlled automated production lines for low concentration organic compounds.

[0046] Please see Figure 1The present invention provides a fully automated low-concentration organic compound production line (hereinafter referred to as the production line), which includes a machine tool 10. On the machine tool 10, a high-pressure extractor 100, a first parallel concentration device 200, an acid bed device 300, a second parallel concentration device 800, a column device 400, a nitrogen blower 500, and a capping liquid addition device 600 are sequentially arranged. At the same time, a first track robot 700 and a second track robot 900 are arranged on the machine tool 100.

[0047] Understandably, the first track robot 700 transports the sample bottle to the high-pressure extractor 100 for high-pressure extraction. After extraction, the first track robot 700 transports the sample bottle to the first parallel concentration device 200 for concentration. After concentration, the first track robot 700 transports the sample bottle to the acid bed device 300 for acid treatment. After acid treatment, the second track robot 900 transports the sample bottle to the second parallel concentration device 800 for secondary concentration. After secondary concentration, the second track robot 900 transports the sample bottle to the column filter device 400 for column treatment. After column treatment, the second track robot 900 transports the sample bottle to the nitrogen evaporator 500 for nitrogen evaporation. After nitrogen evaporation, the capping and liquid addition device 600 caps the sample, thus completing the detection of substances such as dioxins in the sample. This fully automated operation has a high degree of automation, which not only improves personnel safety and reduces labor costs, but also protects the environment and hygiene, and effectively improves the efficiency of sample testing.

[0048] Please see Figure 1 and Figure 2 Specifically, the high-pressure extractor 100 includes a heating device 110, a gas delivery device 120, a liquid delivery device 130, and a movable support 140, wherein the movable support 140 is movably disposed inside the casing of the high-pressure extractor 100 and can extend out of the casing.

[0049] Preferably, the movable support 140 is provided with a drive component, which can drive the movable support 140 by means of cylinder transmission, so that the movable support 140 can extend out of the housing of the high pressure extractor 100.

[0050] Preferably, the heating device 110 includes a heating element and an extraction cell, with the extraction cell fixedly disposed between the heating elements. A first inlet and a second inlet are provided on the extraction cell. A gas delivery device 120 is connected to the first inlet, and a liquid delivery device 130 is connected to the second inlet. The liquid delivery device includes a pipette tip for drawing solution from the sample vial. Of course, the high-pressure extractor 100 is already a mature existing technology.

[0051] Understandably, during operation, the movable support 140 of the high-pressure extractor 100 extends out of the extractor's housing. The first track robot 700 then places the sample bottle on the movable support 140, and the heating device 110 begins to heat up (to the set temperature). The movable support 140 raises the sample bottle support, and the sample solution is extracted proportionally and injected into the extraction cell. Once the pressure in the extraction cell reaches the set value, extraction begins. After extraction is completed, the movable support 140 extends the extraction support 121 for the first track robot 700 to grip, thus completing the extraction process.

[0052] Specifically, a drive assembly (not shown in the attached figure) can be provided on the movable support 140 of the high-pressure extractor 100, which can drive the movable support 140 to extend out of the extractor's housing.

[0053] It should be explained that the drive assembly can use components such as motors, drive cylinders, and lead screws for transmission. Of course, how to achieve the transmission of the drive assembly is a mature technology, so the drive assembly will not be described in detail.

[0054] Please see Figure 1 and Figure 3 Based on the above scheme, the first parallel concentration device 200 includes a water bath heating box 210, a sample bottle support 220 is provided on the water bath heating box 210, and a vacuum concentrator cover 230 is flipped on the water bath heating box 210. The vacuum concentrator cover 230 is connected to the water bath heating box through a flip-top cylinder 240.

[0055] Preferably, a concentration control panel 250 is also provided on the water bath heating box 210. The concentration control panel 250 is electrically connected to the electrical control part of the first parallel concentration device 200 and is used to input production concentration action control commands and generation parameters.

[0056] Understandably, the flip-top cylinder 240 on the vacuum concentrator cover 230 extends outward to open the cover, and the first track robot 700 transports the sample vials that have undergone high-pressure extraction to the sample vial holder 220. The flip-top cylinder 240 then retracts inward to close the cover, and the first track robot 700 transfers the remaining 6 sample vials in the sample vial holder 220 to the high-pressure extractor 100. After extraction is complete, the first track robot 700 and the first parallel concentrator 200 repeat the above actions. After the 12 samples on the sample vial holder 220 have been transferred to the sample vial holder 220 through high-pressure extraction and concentration is complete, the flip-top cylinder 240 extends outward to open the cover, allowing the first track robot 700 to grip it.

[0057] Preferably, the first parallel concentration unit 200 has a total of 24 working positions, and in this production line, the parallel concentration unit requires 12 sample bottles to be concentrated.

[0058] Please see Figure 1 and Figure 4 Based on the above scheme, the acid bed device 300 includes a base plate 310 and a gantry frame 320, a first screw-on mechanism 330 and a shaking mechanism 340 set on the base plate 310. A lifting mechanism 321 is movably set on the gantry frame 320, and a fixed gripper 322 is set at one end of the lifting mechanism 321.

[0059] Preferably, slide rails can be provided on both sides of the base plate 310, the gantry 320 is movably mounted on the slide rails, and the lifting mechanism 321 is mounted on the gantry 320, thereby enabling the fixed gripper 322 to move in three dimensions.

[0060] Please see Figure 1 and Figure 6 Preferably, the first capping mechanism 330 includes a rotating gripper 331, a clamping cylinder 332, and a cap supply bracket 333. The rotating gripper 331 is used to fix the sample bottle and then rotate it. The cap supply bracket 333 provides the cap. The clamping cylinder 332 removes the cap from the cap supply bracket 333 and then fixes it. The capping action is completed under the rotation of the rotating gripper 331.

[0061] Please see Figure 1 and Figure 5 Preferably, the shaking mechanism 340 includes a first motor 341, a connecting arm 342, an eccentric wheel 343, a telescopic cylinder 344, and a fixing plate 345. The output end of the first motor 341 is connected to the eccentric wheel 343, one end of the connecting arm 342 is connected to the eccentric wheel 343, and the other end of the connecting arm 342 is connected to the rocker arm of the shaking mechanism 340. At the same time, the telescopic cylinder 344 and the fixing plate 345 are set on the rocker arm, and the sample bottle is fixed by the fixing plate 345, thereby realizing the shaking action under the action of the first motor 341.

[0062] Please continue reading. Figure 1 and Figure 4 Based on the above scheme, an automatic weighing mechanism 350 is also provided on the base plate 310. The automatic weighing mechanism 350 is used to weigh the sample.

[0063] Specifically, the automatic weighing mechanism 350 includes a weighing balance 351 and a shaking box 352, which is mounted on a guide rail 353.

[0064] Preferably, a bottle rack 3511 is provided on the weighing balance 351. The bottle rack 3511 is connected to a moving cylinder 3510. The moving cylinder 3510 can drive the bottle rack 3511 to move toward the shaking box 352. The bottle rack 3511 is used to place sample bottles. A bottle holder 3512 is provided on the bottle rack 3511.

[0065] Understandably, the first motor 341 starts, which in turn drives the fixed gripper 322 to move. The first track robot 700 transfers the sample bottle to the bottle rack 3511, weighs it, and records the mass of the sample and sample bottle at this time. The moving cylinder 3510 lifts the sample bottle upward, and the liquid injection component (not shown in the figure) injects the solution into the sample bottle. The mass of the solution after water injection is weighed and recorded. A drive device (which can be a cylinder) is set on the guide rail 353. Under its action, the shaking box 352 extends outward so that the outlet is directly facing the mouth of the sample bottle. The shaking box 352 starts to work, causing the powder (commonly sodium sulfate powder) in the shaking box 352 to fall into the sample bottle. The total mass at this time is weighed and recorded.

[0066] Please see Figure 1 , Figure 7 and Figure 8 Based on the above scheme, the column passing device 400 includes multiple column passing units 410.

[0067] Specifically, the column feed unit 410 includes a column feed support 411, with a dispensing nozzle 412 at the top of the column feed support 411. A first column bed 413 and a second column bed 415 are arranged opposite each other in the middle of the column feed support 411. A first detector 414 is arranged on the first column bed 413, and a second detector 416 is arranged on the second column bed 415. A receiving platform 420 is arranged at the bottom of the column feed support 411. The receiving platform 420 is movably arranged at the bottom of the column feed support 411. A waste liquid bottle 421, a sample retention bottle 422, a transfer bottle 423, and a collection bottle 424 are arranged on the receiving platform 420.

[0068] Specifically, the receiving platform 420 can be set on the guide rail, and a slider is set on the receiving platform 420 and the guide rail. The slider is connected to the second motor 430, and the action of the second motor 430 can drive the receiving platform 420 to move on the guide rail.

[0069] Please see Figure 1 and Figure 9 Based on the above scheme, the nitrogen blowing device 500 includes a nitrogen blowing water tank 510. A moving mechanism is provided at the bottom of the nitrogen blowing water tank 510. A nitrogen blowing mechanism 530 and a cleaning mechanism (not shown in the attached figure) are provided at the top of the nitrogen blowing water tank 510. The nitrogen blowing mechanism 530 includes multiple nitrogen blowing needles 531. The cleaning mechanism includes a support arm, a third motor and a nozzle. The nozzle is movably mounted on the support arm. At the same time, the third motor is connected to the nozzle through a transmission belt, thereby driving the nozzle to move on the support arm.

[0070] Please see Figure 10Understandably, the translation mechanism on the nitrogen blowing tank 510 extends the receiving bottle holder, and the second track robot 900 transfers the receiving bottle (from the previous process) that has passed through the column to the receiving bottle holder in the nitrogen blowing machine 500. The nitrogen blowing mechanism 530 descends, inserting the nitrogen blowing needle 531 into the receiving bottle to blow nitrogen gas. At the same time, the nitrogen blowing tank 510 begins to heat the water bath of the receiving bottle in the tank (concentrating the sample solution to constant weight at 60°C in the water bath). After completing the first nitrogen blowing treatment, the cleaning assembly begins to move. The outermost row of collection bottles is cleaned. After cleaning, the translation mechanism of the nitrogen blowing tank 510 extends and moves the second row of collection bottles directly below the cleaning assembly. The third motor rotates and moves the collection bottle above the row of collection assemblies to complete the cleaning of the collection bottles. After cleaning, the translation mechanism of the nitrogen blowing tank 510 retracts and performs a second nitrogen blowing process. After completion, the translation mechanism of the nitrogen blowing tank 510 extends the collection bottle support, and the second track robot 900 sequentially transfers the collection bottles to the next process.

[0071] It should be explained that the movement mechanism 520 and the translation mechanism in the nitrogen blower 500 are mature existing technologies, which can be implemented using guide rails, slide rails or lead screws, so they will not be described in detail.

[0072] Please see Figure 1 and Figure 11 Based on the above scheme, the capping and liquid adding device 600 includes a movable support 610, a receiving bottle support 620, a second capping mechanism 630, and a small cap mechanism 640. A capping gripper 611 is provided at one end of the movable support 610, and the receiving bottle support 620 is located at the lower end of the capping gripper 611. At the same time, the second capping mechanism 630 and the small cap mechanism 640 are both located close to the receiving bottle support 620.

[0073] The second-track robot 900 transfers the nitrogen-blown collection bottles sequentially to the collection bottle support 620 in the capping and liquid-adding device 600. The liquid-adding component adds reagents to the collection bottles on the collection bottle support 620. The rotating clamping cylinder clamps the sample bottles. After the clamping cylinder clamps the caps, it starts to rotate, unscrewing and removing the caps and collection bottles. The motor in the small bottle cap mechanism 640 rotates, extending the small bottle caps. The translation cylinder extends and moves the small bottle caps to the lifting column. The translation cylinder retracts, and the lifting column raises the small bottle caps. The translation cylinder extends (towards the opening of the small bottle caps), and the small bottle caps, opening upwards, are pushed away from the lifting column by the translation cylinder. The movable support 610 removes the screened small bottle caps and moves them to the capping component, where they are screwed on in conjunction with the small bottles. After completion, the movable support 610 places the obtained small bottles on the small bottle support, waiting for manual removal.

[0074] Please see Figure 13Based on the above scheme, the production line also includes a fume hood 20 and a production line control panel 30. The production line control panel 30 is electrically connected to the electrical control part of the production line and is used to input control parameters. Of course, how the electrical control part is controlled is not within the improvement direction of this invention, so it will not be described in detail. The fume hood 20 is covered on the machine tool 10.

[0075] It should be explained that in the above scheme, the first track robot 700 and the second track robot 900 have the same structural features, and the first parallel concentration device 200 and the second parallel concentration device 800 have the same structural features.
