Problems solved by technology
[0002] In physical or chemical experiments, it is often necessary to extract solvents as reagents, especially toxic solvents. In the protection of operators, they usually wear gas masks, wear chemical protective clothing, and operate under ventilated conditions. It is extremely inconvenient, and even if it is protected, it cannot be completely protected, and there are still a small number of volatile toxic substances that cause harm to the human body. In advanced laboratories, robots are used instead of manual operations, but the cost of implementation is high. And it needs to be programmed, which requires high technical requirements for operators. In the prior art, there is still no simple and reliable device that will not cause harm to the human body to achieve the above functions.

The invention discloses an automatic solvent extraction device. The device comprises a base, wherein the base is provided with a convex sleeve; the sleeve is internally sleeved with a slide seat; a suction straw is movably arranged at the center of the bottom face of the slide seat in a sliding manner and an outlet end of the straw movably penetrates through and stretches out of the base; a first spring set is arranged on the bottom face of the slide seat; the first spring set is used for surrounding the straw in the middle and is connected onto the sleeve or the base; the outlet end of the straw is connected with a solvent extraction system; the base is further connected with an automatic hoisting system for controlling the hoisting of the base, so as to further control the straw to remove a cover from a container opening for containing a solvent. The device is simple and reliable and does not cause damages to a human body; a toxic solvent can be automatically extracted and an existing working condition can be improved; the humanized operation is realized, the experiment time is shortened and the working efficiency is improved.
Description
technical field [0001] The invention belongs to the field of harmless treatment, in particular, the invention relates to an automatic solvent extraction device. Background technique [0002] In physical or chemical experiments, it is often necessary to extract solvents as reagents, especially toxic solvents. In the protection of operators, they usually wear gas masks, wear chemical protective clothing, and operate under ventilated conditions. It is extremely inconvenient, and even if it is protected, it cannot be completely protected, and there are still a small number of volatile toxic substances that cause harm to the human body. In advanced laboratories, robots are used instead of manual operations, but the cost of implementation is high. And need programming to realize, higher to the technical requirement of operator, in the prior art, still do not have a kind of device that is simple and reliable and can not cause harm to human body to realize above-mentioned function. ...
