Description

Technical Field

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

[0002] In environmental detection work, it is often necessary to rapidly extract solvents, and a rapid solvent extractor will be used. Extraction, also known as solvent extraction or liquid-liquid extraction, is a unit operation for separating mixtures by taking advantage of the different solubilities of components in a solvent system. That is, it is a method of transferring solute substances from one solvent to another by using the difference in the distribution coefficients of substances in two immiscible solvents. When detecting the environment, the water source in the environment is usually collected and extracted, and the extracted solution is observed to directly understand the pollution status of the environment.

[0003] After extraction is completed, a collection bottle is usually installed at the bottom of the extraction bottle, so that the extracted solution flows into the collection bottle. However, in most extractors, the extraction bottle is above the collection bottle, and the two do not directly contact. Therefore, when the solution flows from the extraction bottle into the collection bottle, a small amount of the solution may be spilled, resulting in waste.

[0004] In search of solutions to the above problems, it is found that in the currently disclosed prior art, such as a rapid solvent extractor proposed in the patent with the publication number CN214286781U, the device is fixedly installed on a lifting plate, and the top of the lifting plate is fixedly connected to the output end of a cylinder. After extraction is completed, the cylinder is started to drive the lifting plate to move downward, so that the bottom end of the extraction bottle extends into the collection bottle. However, since most collection bottles are test tubes, when controlling the downward movement of the extraction bottle, it may be due to over-controlling the downward movement of the cylinder, resulting in the extraction bottle squeezing the test tube and breaking the test tube, affecting subsequent solution collection. Summary of the Utility Model

The blocking block 203 is slidably installed through the through holes of the support plate 202. During the downward movement of the lifting frame 102, the blocking block 203 is inserted into the through holes of the support plate 202, and when the top plate 201 moves downward, it contacts the blocking block 203, thereby restricting the further downward movement of the lifting frame 102.

[0032] In this embodiment, referring to Figure 4 , the liquid collecting component includes a sliding frame 301 and a liquid collecting box 302. There are two sliding frames 301, and the two sliding frames 301 are slidably installed in the chute of the placement plate 4. The liquid collecting box 302 is fixedly installed at the top of the two sliding frames 301, and through holes are provided on the liquid collecting box 302. When the solution flows out of the liquid outlet pipe 7, if the solution splashes out, it can enter the liquid collecting box 302.

[0033] In this embodiment, referring to Figure 5 , it further includes a stirring component. The stirring component includes a motor 401, a stirring shaft 402 and stirring rods 403. The motor 401 is installed at the top of the extraction bottle 1, the stirring shaft 402 is rotatably installed through the extraction bottle 1, and the output end of the motor 401 is fixedly connected to the top end of the stirring shaft 402. There are a plurality of stirring rods 403, and the stirring rods 403 are fixedly installed on the stirring shaft 402. When the motor 401 is started, the motor 401 drives the stirring shaft 402 and the stirring rods 403 to rotate, thereby stirring the solution in the extraction bottle 1.

[0034] In this embodiment, referring to Figure 1 , a liquid inlet pipe 5 is connected and installed at the top end of the extraction bottle 1, a liquid outlet pipe 7 is connected to the bottom end of the extraction bottle 1, and a valve 6 is connected to the liquid outlet pipe 7. The solution is placed into the extraction bottle 1 through the liquid inlet pipe 5, and then after extraction is completed, the valve 6 is opened and the solution flows out through the liquid outlet pipe 7.

[0035] In this embodiment, referring to Figure 1 , the liquid outlet pipe 7 and the collection bottle 2 are located at the same vertical position, so that the solution can flow smoothly into the collection bottle 2.

[0036] In this embodiment, referring to Figure 4 , the through holes provided on the liquid collecting box 302 are the same size as the openings of the collection bottle 2, and the bottom end of the liquid collecting box 302 is in contact with the top end of the collection bottle 2, so that the solution splashed into the liquid collecting box 302 can flow into the collection bottle 2.

Insert the blocking block 203 into the through hole of the support plate 202, and the position of the blocking block 203 at different through holes can be changed according to the different depths of the liquid outlet pipe 7 inserted into the collecting bottle 2. Start the cylinder 103 to drive the lifting frame 102 and the extraction bottle 1 to move downwards. When the top plate 201 touches the groove of the blocking block 203, the blocking block 203 blocks and limits it, so that it will not move downwards. At this time, the bottom end of the extraction bottle 1 does not contact the top of the collecting bottle 2 and the liquid outlet pipe 7 can be inserted into the collecting bottle 2. Then open the valve 6 to make the solution flow into the collecting bottle 2. During the flowing process, if the solution splashes, it can be blocked by the liquid collecting box 302, so that the splashed solution flows into the liquid collecting box 302 and then flows into the collecting bottle 2 again.

[0040] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
