Description

Technical Field

[0001] The utility model relates to the technical field of liquid-liquid extraction of oils and the like in water quality monitoring, and in particular to an oscillator for experimental extraction and a sample bottle suitable for the oscillator. Background Art

[0002] In experiments such as oil in water quality monitoring that require liquid-liquid extraction, the sample needs to be transferred to a separatory funnel, and then the extracting liquid is added to the separatory funnel, and then it is shaken vigorously to allow the extracting liquid to fully contact the petroleum in the sample to achieve effective extraction of the oil. Currently, there are two extraction processes: manual oscillation and mechanical oscillation. Manual oscillation is time-consuming and labor-intensive. Mechanical oscillation has two mechanical processing methods: forward and reverse rotation and vertical oscillation. The forward and reverse rotation method cannot fully emulsify the extractant and affect the extraction efficiency; vertical oscillation cannot effectively deal with situations where the water sample volume accounts for a high proportion.

[0003] For example, the Chinese patent document with application number 202230717276.7 discloses a fully automatic vertical oscillator. Another example is the Chinese patent document with application number 201721399787.9, which discloses a reciprocating flip extraction oscillation device, including an oscillation box, a transmission shaft on one side of the oscillation box is horizontally connected to a control box, the upper and lower bottom surfaces of the oscillation box are hollowed out, a plurality of fixed rods are vertically erected between the inner walls where the two long sides of the box are located to divide the box into a plurality of square frames, a fixed cover is arranged at the center of each square frame, and the fixed cover is connected to the four sides of the square frame through a spring; a box cover is arranged on the box, a plurality of fixed rods are vertically erected between the two long sides of the box cover to divide the box cover into a plurality of square frames, a fixed cover is arranged at the center of each square frame, and the fixed cover is connected to the four sides of the square frame through a spring.

[0004] The above two oscillators have the following problems: first, the existing oscillators all require a separatory funnel, and the sample needs to be transferred from the sample bottle to the separatory funnel. The separatory funnel is fixed by a fixed cover or a fixed buckle before the oscillation procedure is performed. During the transfer process, there is a high risk of contamination and loss of the components to be tested; second, after the oscillation is completed, the process of collecting the extractant from the separatory funnel needs to be manually controlled to separate the water sample and the extractant. Not only is the process time-consuming and labor-intensive, but there is also a certain proportion of error risk; third, the current oscillator fixed cover and fixed buckle are fixed in size and can only be applied to the same model of separatory funnel, but due to the different conditions of actual samples, the reagents The amount is also different. Some samples are large and some are small. Different types of separatory funnels cannot be used according to different amounts of samples. For example, when the volume of water samples accounts for a relatively high proportion, a larger separatory funnel is required. For small samples, the extractant cannot be fully emulsified in a relatively large separatory funnel, which affects the extraction efficiency. Therefore, the existing oscillator limits its application in the laboratory; fourth, the extractant adheres to the inner wall of the separatory funnel and cannot be completely transferred in a short time. The remaining part will pollute the environment in different ways. For some volatile extractants, it is also easy to be released into the air during the separation and transfer process, damaging the health of the experimenters. Summary of the invention
