Technical Field
The utility model relates to an agricultural product testing technical field, specific theory especially relates to an incomplete extraction element of agricultural product farming for incomplete detection of farming.
Background
Before the pesticide in the agricultural products is detected, the pesticide residue in the agricultural products needs to be extracted. The agricultural product pesticide residue extraction is to separate out a plurality of pesticides remained in a sample by adopting a proper organic solvent and a proper method for determination after purification, and is a very key step of pesticide analysis. The quality of the extraction is determined by the choice of solvent and the extraction method. When the extraction solvent is selected, not only the nature of the solvent itself, but also the characteristics of the pesticide and the condition of the sample need to be taken into consideration, and various situations need to be considered when the extraction method is selected.
In the prior art, various pesticides remained in a sample are extracted, the extraction speed is low, and the working efficiency is low; the agricultural product pesticide residue extraction device for pesticide residue detection, disclosed in Chinese patent publication No. CN212621816U, comprises a stirring box, wherein a stirring cavity is formed in the stirring box, a U-shaped plate is arranged at the top of the stirring box, a motor is arranged at the top of the U-shaped plate, a plurality of stirring rods are arranged on an output shaft of the motor, a liquid outlet pipe is arranged at the bottom of the stirring box, an evaporation barrel is arranged below the liquid outlet pipe, a plurality of cylindrical grooves are formed in the inner wall of the evaporation barrel, and heating rods are arranged in the cylindrical grooves; the utility model has the advantages that through the arrangement of the motor, the evaporation barrel and the heating rod, the output shaft of the motor drives the stirring rod to rotate, so that pesticide residues in the sample are blended into acetonitrile; discharging acetonitrile into the evaporation barrel through the liquid outlet pipe, enabling the heating rod and the nitrogen blowing instrument to work, evaporating the acetonitrile in the evaporation barrel, and enabling the liquid volatilization and concentration speed to be accelerated by the nitrogen blowing instrument; so that the evaporation barrel contains high-concentration pesticide residue acetonitrile; the process has the advantages that various pesticides remained in the sample are extracted, the extraction speed is high, and the working efficiency is improved.
In the practice, when smashing the filtration, impurity blocks up the filter screen easily to reduce the life of filter screen, and be not convenient for clear up the filter screen, thereby lead to the inboard impurity of filter screen to influence the use next and draw the effect, consequently, need further improvement.
