Description

Technical Field

[0001] The utility model belongs to the technical field of industrial wastewater sample detection, and particularly relates to an adjustable liquid-liquid extraction device. Background Technique

[0002] At present, a liquid-liquid extraction device is required in the process of industrial wastewater sample detection. The organic pollutants or heavy metals and other pollutants in the wastewater are separated by the extraction method, which is convenient for the staff to analyze the industrial wastewater samples.

[0003] For the existing liquid-liquid extraction device for industrial wastewater sample detection, the water sample and the extraction liquid are added into the extraction bottle, and after shaking evenly, the extraction substances in the water sample are transferred to the extraction liquid, and the extraction liquid is taken out after standing and stratifying. Currently, the liquid-liquid extraction device for industrial wastewater sample detection usually has two shaking methods: hand-cranked type and motor-driven type. Since shaking takes a long time, the motor-driven type is usually adopted. Although the motor-driven type can work for a long time, it does not have the function of adjusting the shaking intensity, which affects the extraction effect when extracting different water samples.

[0004] Therefore, we provide an adjustable liquid-liquid extraction device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable liquid-liquid extraction device. Through the combined setting of a shaking adjustment component and a quick-fixing component, the problem in the prior art that the liquid-liquid extraction device for industrial sewage sample detection does not have the function of adjusting the shaking intensity and affects the extraction effect when extracting different water samples is solved.

The activity opening can facilitate the use of the adjusting rod 402.

[0035] The working principle of the present utility model is as follows: Place the extraction bottle filled with extraction liquid and water sample in the conical jaw 505. Then rotate the knob. The knob cooperates with the screw rod 501 to control the movement of the threaded sleeve 502 and the connecting rod 503. The movement of the connecting rod 503 drives the adjusting ring 504 to move upward. The movement of the adjusting ring 504 squeezes the conical jaw 505, so that the jaw head of the conical jaw 505 clamps and fixes the extraction bottle. This method can be applicable to extraction bottles of different specifications, increasing the application range of the device and facilitating the operation of the staff. Then adjust the shaking frequency according to the water sample and the extraction liquid. When a smaller shaking frequency is required for shaking, fix the bolt 405 in the threaded hole 407 on the outermost side of the turntable 3. Since the rotation range of the adjusting rod 402 increases with the rotation of the turntable 3, the shaking frequency of the fixing plate 401 and the extraction bottle decreases. When a larger shaking frequency is required for shaking, fix the bolt 405 near the axis of the turntable 3. The rotation range of the adjusting rod 402 and the fixing plate 401 decreases, increasing the shaking frequency of the extraction bottle. The corresponding shaking frequency can be changed according to the differences between the water sample and the extract, improving the extraction efficiency and extraction effect.
