Description

Technical Field

[0001] The utility model relates to a solvent extractor, in particular to a rapid solvent extractor, and belongs to the technical field of extractors. Background Art

[0002] Waste gas refers to toxic and harmful gases emitted by humans in the process of production and life. In particular, chemical plants, steel mills, pharmaceutical plants, coking plants and refineries emit strong odors, seriously polluting the environment and affecting human health. In the treatment of waste gas, solvent extraction is required, and extraction refers to the use of the difference in solubility or distribution coefficient of compounds in two immiscible (or slightly soluble) solvents to transfer compounds from one solvent to another. After repeated extractions, most of the compounds are extracted. In experiments or production processes, solvent extractors are used to quickly extract the required compounds.

[0003] Among them, the "rapid solvent extractor" disclosed in the application number "CN202221548819.8" is also an increasingly mature technology, including a support frame, an extraction bottle is arranged on the upper part of the support frame; a protective cover is arranged at the lower end of the extraction bottle, and a groove is arranged at the bottom of the protective cover; a collecting part is arranged at the bottom of the support frame, and the collecting part includes an electric telescopic rod, a collecting bottle, a fixed cylinder, a raised sleeve, a spring and a supporting arc, and a placement groove is arranged inside the fixed cylinder; the raised sleeve is arranged at the upper end of the fixed cylinder; the raised sleeve and the groove are arranged correspondingly; a through groove is arranged at the middle end of the raised sleeve, and one end of the collecting bottle passes through the through groove to the placement groove. The utility model provides a rapid solvent extractor, which prevents the solvent from spilling on the outside of the collecting bottle, and at the same time avoids external impurities from entering the collecting bottle, thereby ensuring the extraction quality. After further retrieval, the "rapid solvent extractor" disclosed in the application number "CN202023169768.1" includes a bottom plate, a guide column, a lifting plate, a lifting assembly, an extraction bottle, a pipe joint, an extraction tube, a switch valve, a limit plate, a heating sleeve, an electric heating wire, and a collecting bottle. The lifting assembly drives the lifting plate to move downward to allow the extraction tube to extend into the collecting bottle. A fixed ring is coaxially sleeved on the extraction tube, and a floating ring is also slidably mounted on the extraction tube. The floating ring is located below the fixed ring, and an elastic member is provided between the two. The elastic member presses against the floating ring and drives the floating ring to move downward. The beneficial effects achieved by the utility model are as follows: the elastic member elastically resists the floating ring, so that the floating ring covers the bottle mouth of the collecting bottle, seals the bottle mouth, reduces the entry of impurities into the collecting bottle, and avoids the phenomenon of solvent spilling during the injection process. By arranging the heating sleeve and the heating wire, the heating wire is energized to generate heat, thereby heating the solvent in the collecting bottle and improving the extraction efficiency.

[0004] However, the above method still has the following defects in actual use: when the collecting bottle is placed in the placement tank, the collecting bottle is easy to collide with the extraction tank, which is inconvenient to quickly collect the collecting bottle. Therefore, the utility model provides a rapid solvent extraction instrument. Utility Model Content
