Abstract
The invention relates to a quick extraction device and a method thereof, which belong to the field of material extraction. The quick extraction device eliminates an extraction tube of a traditional device to enable a condenser to be directly connected with an extraction bottle, thereby enabling the structure of the device to be simple. Furthermore, parts of the quick extraction device are normally used parts, thereby greatly reducing manufacture cost. An extraction sample and an extraction solvent are jointly arranged in the extraction bottle, thereby increasing spaces for the sample to be added in. The method of the quick extraction device uses micro boiling temperature to extract the sample, thereby being short in extraction time, improving extraction efficiency and reducing energy consumption. Shortest time for extraction to be finished is 3 hours.
Description
Technical field
The present invention relates to a kind of quick extraction device and method thereof, belong to material extracting field.
Background technology
In the infrared spectrum analysis of materials such as rubber, nylon, need material extractings such as rubber, nylon, so that the material after the extracting is purer, reduces the spectrum that impurity causes in the material and disturb.
What traditional handicraft was used the extracting of materials such as rubber, nylon is apparatus,Soxhlet's, as shown in Figure 1, claims liposuction device or Soxhlet's apparatus again.Apparatus,Soxhlet's is made up of extraction flask 102, extraction tube 103, condenser 101 3 parts, and extraction tube 103 both sides have siphon pipe and tube connector respectively, and tight can not gas leakage wanted in the each several part junction.During extraction, testing sample is wrapped in the fat-free filter paper bag, put into extraction tube 103.Add acetone in the extraction flask 102, heating and extracting bottle 102, the acetone gasification gets into condenser 101 by the tube connector rising, and the liquid that congeals into splashes in the extraction tube 103, the additive in the lixiviate rubber sample.The acetone liquid level reach a certain height in the pipe 103 to be extracted, and the acetone that is dissolved with additive flows into extraction flask 102 through siphon pipe.The acetone that flows in the extraction flask 102 continues to be heated gasification, rising, condensation, splashes in the extraction tube 103, so moves in circles, till extracting fully.
The shortcoming below yet apparatus,Soxhlet's exists: this apparatus structure is complicated, and particularly siphon pipe and tube connector designing requirement on the extraction tube 103 makes its cost of manufacture higher; Because the restriction of extraction tube 103 lixiviate effects makes the sample size that can pack in the extraction tube 103 little; This method adopts the normal temperature extracting in addition, and the extracting time is long, generally need 24 to 48 hours, so extraction efficiency is low, and energy consumption is big.
Summary of the invention
The objective of the invention is in order to solve the extracting of traditional handicraft, have shortcomings such as the extraction device cost of manufacture is high, extraction efficiency is low, energy consumption is big, and a kind of quick extraction device and method thereof are provided materials such as rubber, nylon.
A kind of quick extraction device of the present invention; Comprise: condenser, extraction flask, condenser is connected through ground with extraction flask, and integral sealing; Extracting sample and extraction solvent are put into extraction flask jointly, and the extraction solvent behind the immersion sample accounts for 1/2～1/3 of extraction flask volume;
A kind of fast extracting method of the present invention:
1) will treat that it is one millimeter granule sample that the extracting sample is processed average diameter, sample coated, after sealing, place the extraction flask of extractor with crocus cloth.
2) extraction solvent being added the 1st) step is placed with in the extraction flask of sample, make to coat good sample and be fully immersed in the extraction solvent, and the extraction solvent that immerses behind the sample accounts for 1/2～1/3 of extraction flask volume.
3) the heating and extracting bottle makes the extraction solvent of choosing to boiling point, is cooled to be higher than this extraction solvent boiling point 10～20 degree and to be incubated more than 1 hour, guarantees that this solvent remains little boiling.
4) extraction solvent after the 3rd step extracting is leached from extraction flask, changes extraction solvent and repeat the 2nd)～the 3rd) the step operation is more than twice, extracting is accomplished.
Beneficial effect:
Adopt extraction device of the present invention simple in structure, removed the extraction tube of conventional apparatus, other two kinds of parts are part commonly used, therefore greatly reduce cost of manufacture, and sample and extraction solvent are put into extraction flask simultaneously, have increased the added space of sample; Method of the present invention adopts little temperature of boiling to the sample extracting, and the extracting time is short, the most only needs accomplish in 3 hours, has improved extraction efficiency, thereby has cut down the consumption of energy.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment content of the present invention is further specified.
A kind of quick extraction device of the present invention, as shown in Figure 2, comprising: condenser 1, extraction flask 2, condenser 1 and extraction flask 2 are connected through ground, and integral sealing;
Use the axle box rubber blanket to be example with rolling stock, the spectrogram that arrives that directly detects of this product through infrared spectrum, as shown in Figure 3, adopt quick extraction device of the present invention to carry out the method for extracting:
1) this rubber blanket product being processed average diameter is one millimeter granule sample, with crocus cloth sample is coated, and after sealing, places the extraction flask 2 of extractor.
2) acetone being added the 1st) step is placed with in the extraction flask 2 of sample, make to coat good sample and be fully immersed in the acetone, and the acetone that immerses behind the sample accounts for 1/3 of extraction flask 2 volumes.
3) heating and extracting bottle 2 makes the acetone of choosing to boiling point, is cooled to 70 degree and is incubated 1 hour, guarantees that this solvent remains little boiling.
4) acetone after the 3rd step extracting is leached from extraction flask 2, adds acetone again and repeat the 2nd)～the 3rd) step operation twice, extracting is accomplished.
5) the rubber blanket product of extracting being accomplished detects through infrared spectrum, obtains spectrogram, and is as shown in Figure 4.
The comparative example
Adopt and use the axle box rubber blanket, after the apparatus,Soxhlet's extraction through traditional handicraft, detect, obtain spectrogram through infrared spectrum with embodiment 1 identical rolling stock, as shown in Figure 5.
Through to this kind elastomeric material through two kinds of methods after extracting is purified respectively; The sample infrared detection spectrogram that obtains compares; The chromatogram characteristic basically identical proves and adopts method of the present invention can reach the extraction rate was acquired that adopts traditional Soxhlet extractor to the effect that sample carries out extracting.
