Embodiment Construction

[0034] The specific implementation of the pesticide residue detection pretreatment system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0035] See attached figure 1 , the pretreatment system for pesticide residue detection is composed of a steel structure frame 1, a workbench 2 is in the middle of the frame 1, a functional unit 4 is arranged above the workbench 2, a mechanical arm unit 3 is arranged on the frame 1, and a workbench 2 is arranged below Cable and pipe layout for circuit air circuit, and waste connection device. The X-axis of the slide rail of the mechanical arm unit 3 is installed on the front and rear sides of the frame 1, and a plurality of mechanical arms are arranged on it, which are divided into a gripper mechanical arm and a pipetting mechanical arm.

[0036] The top of the frame 1 is semi-sealed, and a ventilation mechanism is set on it. There are input and output positions at the front and rea...

Abstract

The invention relates to the technical field of automatic equipment, and discloses a pesticide residue detection pretreatment system. The system comprises functional units and a control unit which are arranged on a workbench of a rack, each functional unit comprises a sample feeding cover opening and closing unit, a liquid and salt adding unit, a weighing oscillation unit, a first centrifugal unit, a first nitrogen blowpipe transferring unit, a nitrogen blowing unit, a solvent adding unit and a filtering unit, the control unit comprises a mechanical arm unit and an electric control unit, the functional units are sequentially arranged on a workbench of the rack along the periphery, and the control unit controls the functional units and the mechanical arm unit to carry out processing work. Automatic operation of pesticide residue detection pretreatment work is achieved, manual operation is reduced, and the working efficiency and the sample consistency are improved.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a pesticide residue detection pretreatment system. Background technique [0002] With the improvement of people's living standards, the requirements for food safety are getting higher and higher, and the country's requirements for pesticide residue inspection are becoming more and more stringent, resulting in more and more samples from pesticide residue testing institutions; while most of the existing testing units are only Mechanization and automation are realized in the detection of pesticide residues, but the sample pretreatment, which accounts for more than half of the entire detection man-hour, is still mainly done manually. [0003] Most of the main pesticide residue detection institutions in my country use acetonitrile extraction in the pre-treatment process of pesticide residues. However, organic solvents pollute the environment and may cause safety hazards ...
