Description
Technical field
The utility model relates to moisture standards substance preparation techniques field, particularly a kind of controlled low moisture content liquid mark thing filling apparatus.
Background technology
Liquid moisture standards material taking methyl alcohol as matrix, although be convenient to sample introduction, prepare also simple, due to the high volatile volatile of methyl alcohol, value less stable.For industries such as oil, chemical industry, light industry, electric power, medicine, agricultural chemicals, environmental protection, geology, food, in sample, micro-water content is an important index, needs to control within the specific limits.For the micro-water content in working sample, need to analyze mensuration with corresponding instrument.
Because the moisture in surrounding environment has certain influence to the water cut of water gauge thing, particularly, in filling liquid process, can cause the steam in environment to enter in package bottle, cause that mark thing moisture content value raises.
Filling referring to packs particular requirement liquid or semifluid into operation in specified containers.The factor that affects filling liquid is a lot, such as viscosity, foamability and minute impurities content etc.The method of filling liquid mainly contains following several at present:
1. normal pressure is filling.Under condition of normal pressure, mainly depend on by the deadweight of filling liquid and flow in specified containers.That this device and method is applicable to is common, filling without particular/special requirement liquid.
2. vacuum and filling.Under subatmospheric condition, carry out filling to appointment liquid.These apparatus and method are applicable to the filling of liquid that viscosity is larger.
3. isobar filling.Under higher than atmospheric condition, reservoir vessel is inflated, made it and filling apparatus formation pressure reduction, utilize liquid deadweight cash gift reservoir vessel.It is filling that these apparatus and method are applicable to liquid beverage.
4. mechanical pressure is filling.Adopt the mechanical pressures such as liquor pump, piston or air lift pump that liquid is clamp-oned in specified containers.These apparatus and method are suitable for the filling of liquid of vicidity.
(the National Institute of Standard and Technology of National Institute of Standards and Technology, NIST) developed the moisture standards material (SRM 2890) taking water saturation octanol solution as matrix, moisture 4.73%, expanded uncertainty is 0.10%, value accurately and reliably, stability and having good uniformity, has obtained extensive accreditation.Most of commercial moisture standards samples are all traceable to SRM2890.But SRM 2890 still has some shortcomings: be 0.05% for water cut desired value, expect relative uncertainty 10%(
k=2) low aqueous specimen, uses this standard substance calibration inconvenient.This is mainly that in sample, moisture can be subject to external environment considerable influence, causes its water cut to change, thereby affects the definite value of sample moisture, cannot complete and trace to the source due in the filling so low water cut liquid standard sample process in laboratory.Therefore it is 0.05% liquid mark thing that the low water content mark thing, being obtained by above-mentioned 4 kinds of Canning Techniques cannot meet water cut desired value.
Utility model content
The purpose of this utility model is to provide the controlled low moisture content liquid mark thing filling apparatus that a kind of laboratory can be used, and overcomes the higher problem of moisture that low water content liquid mark thing pouring process causes.
To achieve these goals, the utility model provides a kind of controlled low moisture content liquid mark thing filling apparatus, comprises organic glass container, the gas bomb of nitrogen is housed, vacuum pump, U-shaped mercury manometr, porcelain dividing plate with holes, molecular sieve, frosted piston valve, drip pan, peace glass bottle rack, long-neck peace glass bottle, the first stainless steel four-way valve, the second stainless steel four-way valve, liquid storage bottle and self-straw that liquid mark thing is housed, the inner bottom part of organic glass container is provided with molecular sieve, the top of molecular sieve is provided with porcelain dividing plate with holes, on porcelain dividing plate with holes, be placed with drip pan, in drip pan, be provided with peace glass bottle rack, on peace glass bottle rack, be plugged with long-neck peace glass bottle, valve port of the top of organic glass container and frosted piston valve is communicated with, four valve ports of the first stainless steel four-way valve respectively with another valve port of frosted piston valve, vacuum pump, the valve port that the gas bomb of nitrogen and the second stainless steel four-way valve are housed is communicated with, three valve ports of residue of the second stainless steel four-way valve respectively with organic glass container, one end of U-shaped mercury manometr and self-straw is communicated with, and the other end of self-straw inserts and is equipped with in the liquid storage bottle of liquid mark thing.
Organic glass container comprises top cover and vessel, and the folding surface of contact of top cover and vessel is set to frosting, and on frosting, scribbles vacuum grease layer.
The lower openings internal diameter of long-neck peace glass bottle is 0.4-0.6mm, and upper opening internal diameter is greater than lower openings internal diameter.
Self-straw is rectangular shaped, and the one end of inserting self-straw in the liquid storage bottle that liquid mark thing is housed is the bell shrinking.
Principle of work of the present utility model is to utilize after organic glass container vacuum-pumping, its internal pressure is lower than external pressure, thereby make moisture liquid mark thing automatically enter long-neck peace glass bottle, consider in the time shifting long-neck peace glass bottle and sealing still in open environment, therefore after vacuumizing, utilize high-purity nitrogen to calm the anger as adding, in pouring process, be pressed into high pure nitrogen, thereby make moisture liquid mark thing in long-neck peace glass bottle shift and sealing process in all the time by nitrogen protection, reduce and avoided influence of moisture in unlimited system, moisture in liquid mark thing is controlled in 50 μ g/ml.
Consider the impact of moisture in plus environmental, whole filling apparatus is totally-enclosed system, avoids the moisture of liquid mark thing moisture in pouring process to be subject to the interference of external environment.
The utlity model has following beneficial effect: this plant operator skill is simple, with low cost, being applicable to laboratory uses, sealing completely, auto-filling, low energy consumption, nothing are given up, environmental friendliness, and the moisture in liquid mark thing can be controlled in 50 μ g/ml, and the definite value that meets low moisture content liquid mark thing is used needs.
