Description
Technical Field
The invention belongs to the technical field of pesticide residue detection equipment, and particularly relates to a schottky bottle oscillation device for pesticide residue detection.
Background
As people pay more attention to food safety and environmental problems, the problem of pesticide residue is more and more concerned by people; various specialized testing institutions and laboratories are also increasingly emerging.
Pesticide residue (hereinafter simply referred to as pesticide residue) refers to the general term for pesticide precursors, derivatives, metabolites, degradants and impurities that remain in the environment, organisms and foods after the pesticide is used. The pesticide residue of agricultural products such as vegetables, melons, fruits, tea leaves and the like is mainly forbidden organophosphorus pesticides, carbamate pesticides and the like, and in addition, various novel pesticides are endless with the development of technology, and hundreds of pesticide residues can be detected. Eating foods containing a large amount of high-toxicity and extremely-toxic pesticide residues can cause acute poisoning accidents of people and livestock; the long-term consumption of agricultural and sideline products with excessive pesticide residues can cause chronic poisoning of people and animals, various diseases, cancers, fetal malformations and the like. Therefore, in order to ensure food safety, pesticide residue detection by periodic or random sampling of the food is required before entering market circulation; in addition, soil, water and the like are also required to be sampled for pesticide residue detection, so that food safety is ensured.
The pesticide residue detection generally comprises the steps of adding an extractant (water, ethanol, acetonitrile, acetone and the like) into a weighed sample for extraction, and then carrying out qualitative or quantitative analysis by a high-efficiency gas phase or liquid phase chromatograph, so as to obtain a detection result of corresponding indexes; in the extraction process, in order to ensure sufficient extraction, a schottky bottle, a test tube and the like filled with a sample and a mixed solution are required to be vibrated uniformly, and a reciprocating shaking table is generally adopted to finish the vibration and shaking.
To reduce cost and improve efficiency, samples are often handled in batches in a laboratory, and a plurality of reagent bottles (reagent bottles typically include a larger 250mL schottky bottle and a smaller 50mL disposable plastic test tube) are shaken on a shaker; the common shaking table adopts two or more movable steel bars (foam is sleeved outside) to clamp the schottky bottle or the reagent bottle between the two steel bars for fixation, the two ends of the steel bars are screwed and fixed on the guide rails on two sides of the shaking table, operators are easy to fix and loose when manually screwing and fixing the steel bars, the shaking process can be loosened to cause the schottky bottle, the test tube and the like to lose fixation, and then the dangerous conditions such as falling or breakage of the schottky bottle and the test tube are caused. The fixing mechanism on the reciprocating shaking table is troublesome and unstable to operate when clamping the Schottky bottle, and has certain potential safety hazard.
In addition, the schottky bottle is often leaked in the shaking process of falling and shaking due to the fact that the bottle mouth is stained with impurities, the inside of the bottle cap is damaged or stained with impurities, the bottle cap is not screwed down due to small force of an operator, and the like when the bottle mouth is used for weighing samples; once leakage occurs, the pollution of the shaking table and laboratory air can be caused, and the error of the detection result is more likely to be increased. In contrast, no matter the stand posture or the fall posture is adopted, the disposable plastic test tube is not easy to leak.
Because reagent in the schottky bottle generally can not be full of, and reagent liquid level has a certain distance to the bottleneck, vertically places the schottky bottle and shakes even can effectively prevent, but operating personnel generally think vertically place shake even extraction and shake the effect not as good as shaking the schottky bottle and fall, and vertically place shake when even schottky bottle more easily take place not hard up, mutually collide and lead to the bottle to break, the loss and the pollution that cause are bigger.

The cover plate is wavy or crenelated, and if necessary, the schottky bottle can be placed on the lower side of the wavy or crenelated cover plate, and a placing space is provided for the schottky bottle just below the wavy or crenelated cover plate.
The two side walls of the accommodating part are provided with clamping gaskets 8. The diameter of a common 50mL disposable plastic test tube is about 3cm (the diameter of a cover of the 50mL disposable plastic test tube is about 3.1-3.2 cm), and the width of the accommodating part can be set to be 6-10cm, so that a hand or a finger can conveniently extend into the accommodating part to pick up the 50mL disposable plastic test tube; the thickness of the clamping gaskets is determined according to the width of the accommodating part, and the distance between the two opposite clamping gaskets is preferably 2.5-3cm, so that the clamping gaskets can clamp and fix 50mL of disposable plastic test tubes.
An annular gasket 9 is arranged at the through hole; the clamping gasket and the annular gasket are made of elastic wear-resistant materials.
The upper surface of the bearing table is provided with limit grooves 10 the number of which is the same as that of the through holes, and each limit groove corresponds to one through hole; the mouth of the limit groove is matched with the diameter of the Schottky bottle.
The limiting groove is arranged right below the corresponding through hole.
The cover plate is preferably made of transparent materials so as to facilitate observation of whether the schottky bottle has the conditions of liquid leakage, unfixed condition, overlarge shaking amplitude and the like.
When the schottky bottle is used, the schottky bottle is placed in the limiting groove in a standing mode, when the cover plate is turned over and closed, the cover 401 of the schottky bottle penetrates through the through hole, and the through hole is clamped on the upper portion of the main body 402 of the schottky bottle to fix the schottky bottle. The schottky bottle that adopts the posture of standing to arrange, although need bigger oscillation frequency and shock time just can reach better shock effect, but the schottky bottle that the posture of standing was arranged not only put the density on the shaking table bigger, also is difficult to take place the condition such as weeping.

Under the same oscillation frequency, the liquid level area of the inclined Schottky bottle is larger, the generated liquid impact and collision in the bottle are stronger, the oscillation effect on the mixed reagent is obviously better than that of the Schottky bottle in a standing posture, and the possibility of liquid leakage and the liquid leakage amount of the mixed reagent are smaller compared with those of the reagent bottle in a falling posture even if the liquid leakage and other conditions occur.
Example 3
As shown in fig. 4, similar to embodiment 2, the difference is that the lower side of the bottom of the limit groove is provided with a recessed extension 12.
And a collision bead 13 is arranged in the limiting groove, and the diameter of the collision bead is smaller than the width of the extension part.
During operation of the shaking table, the bump beads are driven by shaking to bump the schottky bottle, so that the schottky bottle generates additional vibration, a sample adhered to the bottom inside the schottky bottle is separated from the bottle wall, and the shaking effect of the shaking table can be enhanced.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown, it is well suited to various fields of use for which the invention is suited, and further modifications may be readily made by one skilled in the art, and the invention is therefore not to be limited to the particular details and examples shown and described herein, without departing from the general concepts defined by the claims and the equivalents thereof.
