Description
[technical field]
The utility model relates to a kind of digestion tube, specifically a kind of efficiency multi-functional digestion tube high, easy to use of clearing up.
[background technology]
In the time measuring the metallic element of solid sample, all need to clear up processing, clear up the upper machine mensuration of carrying out again sample after having reacted.In the time clearing up processing, can guarantee sample thoroughly to react completely, can completely sample be transferred in the solution of upper machine mensuration, these factors can affect the accuracy of sample determination.Make to measure accurately, the whole process of clearing up processing is crucial, and wherein digestion tube has played decisive role.At present, clearing up solid sample digestion tube used is quartz or teflon digestion tube substantially, an additional lid, so just easily produce following problem: when digestion solution and sample are placed in quartz or teflon digestion tube, when cover lid heating and decompose, reaction is fierce, gas is easily washed lid open, in addition along with clearing up the carrying out of reaction, steam in quartz or teflon digestion tube condenses on lid, liquid flows to quartz or teflon digestion tube outside by the gap between quartz or teflon digestion tube and lid, loss partially liq, bring certain error to measurement result.Certainly, also have some improved digestion tubes, such as having added some lids that cave in, reduce outside liquid effuser, but reaction is when fierce, also can wash lid open; Some has added a gas outlet on lid, but cannot solve intense reaction time, liquid can be gone out from gas outlet, loss part solution, the accuracy that impact is measured, in addition, existing teflon digestion tube is positively to observe liquid in pipe amount, uses extremely inconvenient.
[utility model content]
The purpose of this utility model is to solve the problem that above-mentioned technology exists, provide a kind of clear up efficiency high, easy to use, can observation tube in the multi-functional digestion tube of liquid volume and color.
To achieve these goals, the technical solution adopted in the utility model is: multi-functional digestion tube, comprise body and block, and described body is provided with transparent window, for observing liquid in pipe situation.
On described transparent window, be provided with scale mark, for estimating measuring tube inner volume.
Described transparent window is to be embedded in described tube wall, and described transparent window and described tube wall merge one.
Described pipe diameter is 12mm～18mm, is highly 120mm～140mm, like this can more applicable follow-up test.
Described block is provided with the combining cover edge of matching with described body lateral wall screw thread, and block is not easy to come off like this.
At described body, near opening part setting " Z " type relief hole, and described combining cover is along being provided with the pressure guide hole matching with described " Z " type relief hole, for pressure release.
Cylindrical tube, porous interlayer and steam buffer chamber are set in described block, and described porous interlayer is fixedly connected with block sidewall, forms steam buffer chamber at described block, and described cylindrical tube is fixed on described porous interlayer outer surface.
Described steam buffer chamber arranges steam export mouth for being connected with steam delivery line.
Compared with prior art, the utility model has the following advantages: sample can be sealed in and in body, carry out heating high-pressure and clear up, after having cleared up, body directly can be carried out to colorimetric estimation, and color and volume in can observation tube, also have high temperature resistant, corrosion-resistant, clear up that efficiency is high, one tube multipurpose, the advantage such as easy to use.
[brief description of the drawings]
Fig. 1 is the structural representation of the multi-functional digestion tube of the utility model.
[embodiment]
Below in conjunction with the drawings and specific embodiments, the multi-functional digestion tube of the utility model is described in detail.
Multi-functional digestion tube, as shown in Figure 1, comprises body 1 and block, and described body 1 is provided with transparent window 12, for observing liquid in pipe situation.On described transparent window 12, be provided with scale mark 13, for estimating measuring tube inner volume.Wherein, described transparent window is to be embedded in described tube wall, merges one with described tube wall.Described body 1 diameter is 12mm～18mm, be highly 120mm～140mm, like this can more applicable follow-up test, the length of this body is longer, in the time of heating and decompose, the temperature at mouth of pipe place can not rise too high, operating personnel can hold place suitable for reading operation, are conducive to improve digestion condition and increase cooling effect, prevent breakage.Preferably, body 1 diameter is 14mm～16mm, is highly 125mm～135mm.Upper shed place at body 1 has external thread, and described block 2 is provided with the combining cover matching with described body lateral wall screw thread along 21, and block is not easy to come off like this.At described body 1, near opening part setting " Z " type relief hole 14, and described combining cover is provided with the pressure guide hole 24 matching with described " Z " type relief hole along 21, for pressure release.
Cylindrical tube 22, porous interlayer 25 and steam buffer chamber 27 are set in described block, and described porous interlayer 25 is fixedly connected with block sidewall, forms steam buffer chamber 27 in described block, and described cylindrical tube 22 is fixed on described porous interlayer 25 outer surfaces.Described porous interlayer 25 arranges some through holes 23; Described steam buffer chamber 27 arranges steam export mouth 26 for being connected with steam delivery line.In the time that steam enters cylindrical tube 22, can condense into liquid, be directly back to body 1; Another part steam can enter into steam buffer chamber 27 by the porous interlayer 25 outside cylindrical tube 22, and now a part of steam condensation becomes liquid, is back in body 1 by porous interlayer 25, and the incoagulable steam of another part can be discharged from steam export mouth 26.This device, just evaporation is dry can not make digestion solution and sample also have little time complete reaction, and the liquid condensing in digestion process can not flow out body 1 yet.
As described above, it is only this novel preferred embodiment, when not limiting with this scope of this novel enforcement, the simple equivalence of generally doing according to this novel claim and novel description changes and modifies, and all still belongs in the scope that this new patent contains.
