Description
Technical field
The utility model relates to a kind of elemental silicon determinator.
Background technology
Industrial silica fume often uses as adjuvant in many composite refractories, but the national standard method of existing detection industrial silica fume, only be applicable to that elemental silicon content is higher than 99.6% bulk product, and the grade that fire resistive material is used always is 95%, sometimes industrial silicon also mixes with other materials, especially when sneaking into other siliceous material (as: silica sand) in the industrial silicon, as adopt existing GB analytical approach, to cause assay gross error to occur, can't detect the accurate content of elemental silicon in the sample at all accurately.If utilize under elemental silicon and the dilute alkaline soln heating condition character that generates hydrogen, thereby calculate the content of elemental silicon, then can determine the content of elemental silicon comparatively accurately by the volume that calculates hydrogen.But this method has certain defective.Because the volume temperature influence of gas is very big, so require the temperature unanimity of the whole device in reaction front and back usually, if inconsistent needs utilize the gas volume equation to proofread and correct, this process need accurately measure the active volume of reaction unit, but accurately measure the active volume more complicated, if can guarantee the temperature unanimity of the whole device in reaction front and back, then do not need to have carried out volume correction, just can guarantee to determine comparatively accurately the content of elemental silicon.
Summary of the invention
The utility model purpose provides a kind of elemental silicon determinator, and this device can guarantee reaction front and back temperature unanimity, and can accurately measure the elemental silicon of different content.
For achieving the above object, the utility model is realized by the following technical solutions:
A kind of elemental silicon determinator, comprise spherical condensation tube, eudiometer tube, reference pipe, leveling bottle, gas cylinder, water bath, conical flask, it is characterized in that, this device is provided with thermostat, and the outside at eudiometer tube is provided with condenser jacket, and thermostat, spherical condensation tube, condenser jacket, water bath are connected by connecting pipe successively and constitute the circulating condensing system.
This device also is provided with the level meter of auxiliary reading, is arranged between eudiometer tube and the reference pipe.
Described condenser jacket upper end is a hatch frame, and condenser jacket communicates with spherical condensation tube by the inlet connecting pipe, and condenser jacket is connected with water bath by outlet connecting pipe.
Described condenser jacket and eudiometer tube are demountable structure.
Described thermostat can be the tank that has water delivering orifice that mixture of ice and water is housed, and perhaps is the recirculated water cooling pump, perhaps is constant temperature water bath.
Compared with prior art, the beneficial effects of the utility model are: the utility model has increased a thermostat on original low content elemental silicon determinator (Fig. 4) basis, in the eudiometer tube outer setting condenser jacket, can guarantee the whole unit temp unanimity in reaction front and back, do not need volume correction during calculating, improve the accuracy of measuring, and can be used to measure the elemental silicon of different content after the transformation of instrument process, thereby enlarged measurement range.
