[0010] When diluting the extracted hydroxy acrylate by setting up a sample preparation module, first pour the hydroxy acrylate and the diluent into the dilution cylinder, then place the dilution cylinder in the first rotating circular frame, and then start the electric drive rod.

When the syringe moves to the upper part of the sample bottle, at this time, the electric telescopic rod two is started to drive the needle on the syringe below the lifting hollow cylinder to enter the sample bottle. Then, the servo motor is started, and the rotating support rod is driven to rotate by the servo motor, so that the push-pull rod drives the quick clamping plate on the opposing slider to clamp the piston shaft of the syringe. Then, the electric telescopic rod three is started, and the lifting frame is driven to rise by the electric telescopic rod three, so that the piston shaft of the syringe rises, and the syringe sucks the sample inside the sample bottle. After the suction is completed, the syringe is moved to the upper part of the sampling inlet, and the piston shaft of the syringe is driven to descend by the electric telescopic rod three, and the sucked sample is injected into the sampling inlet.

[0016] A method for using a detection device for acrylic hydroxy ester processing, using a detection device for acrylic hydroxy ester processing as described above, includes the following steps:

[0017] Step 1. When diluting the extracted acrylic hydroxy ester, first pour the acrylic hydroxy ester and the diluent into the dilution cylinder, then place the dilution cylinder in the first rotating circular frame, and then start the electric drive rod. At this time, the second rotating circular frame descends, and at the same time, the dilution cylinder is clamped and fixed by a plurality of arc-shaped clamping plates located inside the first rotating circular frame and the second rotating circular frame;

[0018] Step 2. Start the drive motor, drive the first belt by the drive motor to make the rotating cylinder rotate, drive the rotating support rod to rotate through the rotating cylinder, so that the dilution cylinder rotates vertically. When the rotating support rod rotates, at this time, the second bevel gear rotates under the limit of the first bevel gear, so as to drive the second belt through the linkage round rod to make the first rotating circular frame drive the dilution cylinder to rotate horizontally;

[0019] Step 3. After dilution is completed, insert the suction pipe into the extraction pipe orifice on the dilution cylinder, and then start the suction pump. The diluted sample is transported to the sieve frame through the suction pump. When the diluted sample enters the sieve frame, the insoluble impurities in the diluted sample are first filtered by the filter plate;

[0020] Step 4. While the filter plate is filtering, start the universal motor, drive the semi-circular gear to rotate through the universal motor. When the tooth block end of the semi-circular gear meshes with the linkage tooth rod, at this time, the linkage tooth rod drives the filter plate on the lifting T-shaped block to descend. At this time, the return spring located outside the guiding cylinder is stretched and squeezed. When the semi-circular gear is separated from the linkage tooth rod, at this time, the return spring rebounds rapidly, so that the filter plate rebounds and vibrates rapidly. The filtered diluted sample is precisely fed into the sample bottle on the rotating push platform through the electronic sample feeding pipe.

At the same time, when the diluted sample is detected, a filtering operation is performed on it to avoid clogging of the chromatographic column by insoluble impurities, thereby improving the detection accuracy and efficiency.

Then, the sample is detected by the gas chromatography detection box 1, and the detected data is collected and analyzed at the same time.

[0046] A method for using a detection device for processing acrylic hydroxy esters, using a detection device for processing acrylic hydroxy esters as described above, includes the following steps:

[0047] Step 1: When diluting the extracted acrylic hydroxy ester, first pour the acrylic hydroxy ester and the diluent into the dilution cylinder 502, then place the dilution cylinder 502 in the first rotating circular frame 519, and then start the electric drive rod 523. At this time, the second rotating circular frame 524 descends, and at the same time, the dilution cylinder 502 is clamped and fixed by a plurality of arc-shaped clamping plates 521 located inside the first rotating circular frame 519 and the second rotating circular frame 524;

[0048] Step 2: Start the drive motor 509, drive the first belt 510 by the drive motor 509 to make the rotating cylinder 512 rotate, drive the rotating support rod 514 to rotate by the rotating cylinder 512, so that the dilution cylinder 502 rotates vertically. When the rotating support rod 514 rotates, at this time, the second bevel gear 516 rotates under the limitation of the first bevel gear 513, so that the second belt 517 is driven by the linkage round rod 515, and the first rotating circular frame 519 drives the dilution cylinder 502 to rotate horizontally;

[0049] Step 3: After dilution is completed, insert the suction pipe 527 into the extraction pipe orifice 503 on the dilution cylinder 502, and then start the suction pump 525. Through the suction pump 525, the diluted sample is transported into the sieve frame 505. When the diluted sample enters the sieve frame 505, the filter plate 532 first filters the insoluble impurities in the diluted sample.

[0050] Step 4: While the filter plate 532 is filtering, start the universal motor 540. Drive the semi-circular gear 539 to rotate through the universal motor 540. When the tooth block end of the semi-circular gear 539 meshes with the linkage tooth bar 536, at this time, the linkage tooth bar 536 drives the filter plate 532 on the lifting T-shaped block 530 to descend. At this time, the return spring 534 outside the guiding cylinder 533 is stretched and squeezed. When the semi-circular gear 539 is separated from the linkage tooth bar 536, at this time, the return spring 534 rebounds rapidly, so that the filter plate 532 rebounds and vibrates rapidly. The filtered diluted sample is accurately fed into the sample bottle body 508 on the rotary pushing platform 507 through the electronic sample laying pipe 529.

[0051] Working principle: When diluting the extracted hydroxy acrylate, first pour the hydroxy acrylate and the diluent into the dilution cylinder 502, then place the dilution cylinder 502 in the first rotating circular frame 519, and then start the electric drive rod 523. At this time, the second rotating circular frame 524 descends, and at the same time, the dilution cylinder 502 is clamped and fixed by a plurality of arc-shaped clamping plates 521 located inside the first rotating circular frame 519 and the second rotating circular frame 524. Start the drive motor 509, and drive the first belt 510 through the drive motor 509 to make the rotating cylinder 512 rotate. Drive the rotating support rod 514 to rotate through the rotating cylinder 512, so that the dilution cylinder 502 rotates vertically. When the rotating support rod 514 rotates, at this time, the second bevel gear 516 rotates under the limit of the first bevel gear 513, so as to drive the second belt 517 through the linkage round rod 515 to make the first rotating circular frame 519 drive the dilution cylinder 502 to rotate horizontally. After dilution, align the suction pipe 527 with the extraction pipe orifice 503 on the dilution cylinder 502 and insert it. Then start the suction pump 525, and convey the diluted sample to the sieving frame 505 through the suction pump 525. When the diluted sample enters the sieving frame 505, first filter the insoluble impurities in the diluted sample through the filter plate 532. While the filter plate 532 is filtering, start the universal motor 540, and drive the semi-circular gear 539 to rotate through the universal motor 540. When the tooth block end of the semi-circular gear 539 meshes with the linkage tooth rod 536, at this time, the linkage tooth rod 536 drives the filter plate 532 on the lifting T-shaped block 530 to descend. At this time, the return spring 534 located outside the guide cylinder 533 is stretched and squeezed. When the semi-circular gear 539 is separated from the linkage tooth rod 536, at this time, the return spring 534 rebounds quickly, so that the filter plate 532 rebounds and vibrates quickly. The filtered diluted sample is accurately fed into the sample bottle 508 on the rotating pushing platform 507 through the electronic laying tube 529. When detecting the sample inside the sample bottle 508, at this time, control the adjustment slider 602 to move inside the first guide rail 601 through the first electric telescopic rod 603, and control the position of the lead screw nut slider 605 inside the second guide rail 604 through the lead screw 607, so that the syringe 614 reciprocates above the sample bottle 508 and the injection port 4. When the syringe 614 moves above the sample bottle 508, at this time, start the second electric telescopic rod 609 to drive the needle on the syringe 614 below the lifting hollow cylinder 610 to enter the sample bottle 508. Then start the servo motor 615, and drive the rotating support rod 616 to rotate through the servo motor 615, so that the push-pull rod 618 drives the fast clamping plate 621 on the opposing slider 620 to clamp the piston shaft of the syringe 614. Then start the third electric telescopic rod 613, and drive the lifting frame 612 to rise through the third electric telescopic rod 613, so that the piston shaft on the syringe 614 rises, so that the syringe 614 sucks the sample inside the sample bottle 508. After the suction is completed, move the syringe 614 above the injection port 4,The piston shaft of the syringe 614 is driven to descend by the electric telescopic rod three 613, and the aspirated sample is injected into the injection port 4. Then, the sample is detected by the gas chromatography detection box 1, and the detected data is collected and analyzed.
