Description
Technical field
This utility model relates to a kind of storage facility of solution, is specifically related to a kind of storage facility of sodium hydroxide titration liquid.
Background technology
Sodium hydroxide titration liquid is one of conventional volumetric solution, version " Chinese Pharmacopoeia " being defined as sodium hydroxide titration liquid storage item in 2010: put in vinyon bottle, sealing is preserved; Have 2 holes in plug, each insertion glass tubing 1 in hole, a pipe is connected with sodica calx pipe, and a pipe is for this liquid of sucking-off.But adopt glass tubing in sodium hydroxide titration liquid storage facility, glass tubing contacts with sodium hydroxide titration liquid for a long time, the silicon dioxide contained in glass can be sent out with sodium hydroxide and answer, thus affects the quality of sodium hydroxide titration liquid; Chinese patent ZL 201220391108.4 utility model patent mentions a kind of sodium hydroxide titration liquid storage facilities, pressuring method must be adopted to discharge, firmly too fast excessive, sodica calx is not only easily made to enter in sodium hydroxide titration liquid, also may cause the moisture in the not divisible air of sodica calx and carbon dioxide, and affect the quality of sodium hydroxide titration liquid.And along with sodium hydroxide titration liquid fewer and feweri, required pressure is larger, more easily introduces the carbon dioxide in air and moisture; Sodica calx adopts conical flask splendid attire, and air only filters by the sodica calx of very thin one deck, and the utilization rate of sodica calx is low, can not play the effect of moisture in good filtered air and carbon dioxide, finally still can affect the quality of sodium hydroxide titration liquid.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of storage facility of convenient and practical sodium hydroxide titration liquid, do not need to provide extra power, only by self gravitation, this volumetric solution is got rid of, can also prevent the water in outside air and carbon dioxide from entering in sodium hydroxide titration liquid, ensure the quality of sodium hydroxide titration liquid, and can stably store sodium hydroxide titration liquid.
Concrete technical scheme of the present utility model is:
A kind of storage facility of sodium hydroxide titration liquid, comprise storage bottle I and storage bottle II, described storage bottle I arranged outside has slot, described slot is provided with vertical opening and in slot, places storage bottle II, the top of described storage bottle I is connected by connection tube with the lower end of storage bottle II, described connection tube is provided with valve I near one end of storage bottle I, and described storage bottle I lower end is provided with the outlet with valve II, and described storage bottle II upper end is provided with the import II with valve III.
Described storage bottle I is used to storage sodium hydroxide titration liquid, and the material of the outlet with valve II that described storage bottle I and lower end thereof are arranged all adopts polypropylene plastics to make; Described storage bottle II is used to storage sodica calx, and its material is also polypropylene plastics, and the connection tube between storage bottle I and storage bottle II is also polypropylene plastics, avoid and use glass material on the impact of sodium hydroxide titration liquid quality, and light transmittance is good; Described storage bottle II is placed in slot, the vertical opening that described slot is arranged on the one hand can after observe sodica calx and whether go bad, connection tube can be placed easily on the other hand; Described storage bottle II adopts long tube to design, and air need through longer sodica calx layer, and the utilization rate of sodica calx is higher, remove moisture in air and carbon dioxide more complete; In described storage bottle II, the storage capacity of sodica calx is lower than the import II on storage bottle II.
Described storage bottle I is provided with import I, and be the loading port of sodium hydroxide titration liquid, described import I adopts screw socket to design, and has the projection that a circle is more smaller than mouth pipe diameter, do not need another shimming can ensure the sealing of sodium hydroxide titration liquid storage part in lid.
Described storage bottle II upper end is provided with the import II with valve III, can open valve III like this when sodium hydroxide titration liquid released by needs, when only needing storage sodium hydroxide titration liquid, and valve-off III.
Described slot is provided with colorimetric card, the sodica calx be used in observation storage bottle II is the need of having changed, this sodica calx is pink granule, faint yellow or canescence is become after absorbing carbon dioxide, when if desired changing, valve I on connection tube can be closed, the quality of sodium hydroxide titration liquid can be ensured so better.
When using sodium hydroxide titration liquid, open valve I, valve III successively, open valve II again, sodium hydroxide titration liquid flows out under gravity, the pressure store in bottle I is reduced, air enters from import II under ambient pressure, storage bottle II through being equipped with sodica calx removes moisture content in outside air and carbon dioxide, then the storage bottle I that sodium hydroxide titration liquid is housed is entered through connection tube, ensure the quality of sodium hydroxide titration liquid with this, when maintenance sodium hydroxide titration liquid stream goes out simultaneously, pressure is stable; When being finished sodium hydroxide titration liquid, valve-off II, valve I, valve III, to store sodium hydroxide titration liquid better.
This utility model is convenient and practical, by being equipped with the storage bottle I of sodium hydroxide titration liquid and storage bottle II Integral design of sodica calx being housed, both easy to use, laborsaving, and storage bottle II can be avoided again to fall the possibility smashed because of carelessness; This device makes sodium hydroxide titration liquid flow out under gravity, avoid introducing excess air, and except the moisture content in outside air and carbon dioxide, the quality of sodium hydroxide titration liquid can be ensured with this, the stable of pressure when sodium hydroxide titration liquid stream goes out can be maintained simultaneously.
