S14: the sample cup is positioned on the sample weighing precision balance, the first pneumatic lifting platform lifts the sample weighing precision balance and the sample cup, so that the weight of an empty sample cup is automatically weighed after the sample cup leaves the conveying chain, and data information is transmitted to the DCS control system;
S15: after the sample weighing precision balance automatically removes the weight of the empty cup, 25-30 g of the minced beet sample falls into the sample cup of the beet sample filtrate automatic preparation device, and in addition, 30-50 g of the beet sample is sealed by a manual label, and the retention time is one year;
s16: the sample weighing precision balance accurately weighs the beet sample again and transmits data information to the DCS control system;
s17: then the second pneumatic lifting platform drops, the conveying chain conveys the sample cup to a dosing position, the photoelectric switch detects that the sample cup is in place, the sample cup is ensured to reach a preset dosing position, the conveying chain stops moving, the sample cup is positioned on the dosing weighing precision balance, the second pneumatic lifting platform lifts the dosing weighing precision balance, and after the sample cup is separated from the conveying chain, the sample cup waits for adding a medicament;
S18: the DCS control system enables the injection pump to work according to the sample weighing data information in the step S16, and an adaptive amount of basic lead acetate medicament is added into the sample cup;
S19: the injection pump is automatically turned off after a proper amount of sample solution is obtained through weighing by a dosing weighing precision balance;
s20: after the medicament is filled, the second pneumatic lifting platform drops, and the conveying chain conveys the sample cup to a grinding and stirring position;
S21: the automatic grinding stirrer pulverizes and grinds plant tissues of the sample added with the reagent, and the grinded sample is sent to a sample pouring position through a conveying chain;
s22: the pressing ring cylinder of the filtrate extraction mechanism drives the rubber pressing ring to press downwards, the filter paper is compacted on the table top, the sample cup is poured, and the sample solution is poured into the pressing ring;
S23: part of the residual sample liquid is dripped into the cleaning water receiving tank, the sample cup is turned to the lower side, the limiting strip supports the sample cup, and the sample cup is conveyed to a cleaning and drying position under the drive of the conveying chain to clean and dry the sample cup;
S24: the DCS control system starts a cleaning program firstly, residual liquid flows into a cleaning water receiving tank, then starts a blower to blow a sample cup to dry, and finally sends the cleaned sample cup to a sampling position to enter the next cycle under the transmission of a conveying chain;
S25: after the sample solution is poured into the pressing ring, the vacuum pump is turned on, the vacuum suction filter tube is used for exhausting air, the filtering efficiency is accelerated, after the filtrate is extracted, the vacuum pump is turned off, and the detection filtrate with the volume of at least 50ml is obtained in the filtrate cup;
s26: the pressing ring cylinder rises, the pressing ring is automatically opened, the unreeling motor drives the unreeling roller to unreel, the paper collecting motor drives the paper collecting counter roller to automatically roll the used filter paper and filter residues, and the filter paper and the filter residues are put into a filter paper filter residue box;
S27: and (3) sending the detection filtrate obtained in the step (S25) into an optical rotation sugar detector for analysis, and automatically counting information big data storage and accounting settlement through a DCS control system.
