Description
Technical field
This utility model relates to a kind of chemical industry instrument, particularly to a kind of vacuum sampler.
Background technology
In chemical process, generally require reaction process material in reactor being sampled detection to determine in reactor.If but adopt the mode of hand sample in a kettle., need on the one hand to suspend reaction, but the special sex determining reaction of some reaction also cannot just cannot be carried out hand sample by intermediate suspension, the manual increase operation easier of sampling in a kettle. has potential safety hazard simultaneously on the other hand.
The Chinese patent that publication number is 203587388U discloses a kind of vacuum sampler, it can be avoided that the manual problem absorbing sample in a kettle., and it is very easy to have operation, feature with low cost, but this vacuum sampler sampling pipe and reflux line are separately provided, cause that sample remains in the duct more, affect productivity.
Utility model content
The purpose of this utility model is to provide a kind of vacuum sampler.This vacuum sampler can reduce the residual causing reactant liquor on pipeline because of reactant liquor is sampled, thus improving productivity.
Above-mentioned technical purpose of the present utility model has the technical scheme that
A kind of vacuum sampler, stretch into the siphon of still intracavity bottom through reactor including one, described siphonal top is connected to sampling bottle, described sampling bottle is connected to evacuation tube and air inlet pipe, described evacuation tube is connected to vacuum pump away from the one end being connected with sampling bottle, described evacuation tube is provided with and controls the first adjustment valve that evacuation tube opens and closes, described air inlet pipe is provided with and controls the second adjustment valve that air inlet pipe opens and closes, described sampling bottle is provided with the return duct for back flow of sample to reactor, described siphon is connected to and controls the 3rd adjustment valve that siphon opens and closes, it is characterized in that: described return duct includes the first return duct, second return duct, described first return duct connects sampling bottle, described second return duct coupled reaction still, described first return duct and the second return duct are connected by reversal valve and are connected to probe tube by reversal valve.
By adopting technique scheme, because all more or less can there is residual on the pipeline flowed through in reactant liquor, and the part pipeline of the first return duct and probe tube is merged, thus reducing because reactant liquor sampling is caused reactant liquor residual on pipeline, thus improving productivity.
This utility model is further arranged to: be provided with in described sampling bottle for showing the liquidometer of liquid level in sampling bottle.
By adopting technique scheme, sampling bottle arranges liquidometer such that it is able to from liquidometer, draw the sample size in sampling bottle, it is to avoid sampling amount is too small or excessive.
This utility model is further arranged to: described second return duct connects with siphon away from the one end connected with reversal valve.
By adopting technique scheme, wanting to connect with siphon by the second return duct, the same part pipeline that merges, minimizing is because causing reactant liquor residual on pipeline to reactant liquor sampling.

Detailed description of the invention
Below in conjunction with accompanying drawing 1, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made the amendment not having creative contribution as required by those skilled in the art after reading this specification, but as long as being affected by the protection of Patent Law in right of the present utility model.
A kind of vacuum sampler, including siphon 1, sampling bottle 2, evacuation tube 3, air inlet pipe 4, return duct 8.One end of siphon 1 is through reactor and stretches into abdomen intracavity bottom, and the other end is connected with sampling bottle 2.Preferably, siphon 1 is connected to the middle part of sampling bottle 2.One end of evacuation tube 3 and one end of air inlet pipe 4 are all connected with the top of sampling bottle 2, and the other end of evacuation tube 3 is connected with vacuum pump 11, the other end connection air of air inlet pipe 4.Return duct 8 one end connects sampling bottle 2, other end coupled reaction still.Preferably, one end of return duct 8 connects the bottom with sampling bottle 2, and the other end is connected to the top of reactor.
Evacuation tube 3 is provided with the first adjustment valve 5, is used for controlling evacuation tube 3 and opens and closes.Air inlet pipe 4 is provided with the second adjustment valve 6, is used for controlling air inlet pipe 4 and opens and closes.Siphon 1 is provided with the 3rd adjustment valve 7, is used for controlling siphon 1 and opens and closes.
Return duct 8 includes the first return duct 81 and the second return duct 82.First return duct 81 one end connects the bottom of sampling bottle 2, and the other end is connected with the second return duct 82 by reversal valve 9.Second return duct 82 connects with siphon 1 away from the one end connected with reversal valve 9.First return duct 81 and the second return duct 82 are connected by reversal valve 9 and are passed through reversal valve 9 and be connected to probe tube 10.
Sampling bottle 2 is provided with the liquidometer 12 for showing liquid level in sampling bottle 2.
Because all more or less can there is residual in reactant liquor, and merged by the part pipeline of the first return duct 81 and probe tube 10 on the pipeline flowed through, thus reducing because reactant liquor sampling is caused reactant liquor residual on pipeline, thus improving productivity.Wanting to connect with siphon 1 by the second return duct 82, the same part pipeline that merges, minimizing is because causing reactant liquor residual on pipeline to reactant liquor sampling.Sampling bottle 2 arranges liquidometer 12 such that it is able to from liquidometer 12, draw the sample size in sampling bottle 2, it is to avoid sampling amount is too small or excessive.
