Abstract
The utility model relates to a multifunctional electronic density measuring instrument which comprises a float body, a supporting line and an electronic weighing device, wherein the supporting line connected with the float body is hung on the electronic weighing device. The electronic weighting device -- an electronic balance or an electronic hanging scale is used as a carrier, the Archimedes law is used for measuring the quality of liquid discharged by the float body, and thus, the multifunctional electronic density measuring instrument simultaneously has the functions of weighing the weight and accurately and quickly measuring density, relative density, sugar degree, alcoholic degree, solute content, etc., and is suitable for measuring liquids with high density, high adhesiveness, high temperature, volatility and corrosiveness.
Description
The utility model relates to multifunction electronic density instrument, be specifically a kind of with electronic weighting equipment (electronic balance or electronics hang title) as carrier, utilize Archimedes' principle to carry out accurately fast and measure fluid density on a large scale and the device of relative density, pol, alcoholic strength, solutes content.
In the present medicine food industry, traditional relative density assay method is to stipulate according to Chinese Pharmacopoeia, adopt pycnometer method, be that a pycnometer is filled with liquid, after placing water bath with thermostatic control to reach constant temperature, taking-up is wiped the liquid that bottleneck overflows away with paper and is wiped away and do the outer globule of bottle, in the same pycnometer quality of weighing solution and water purification respectively, thereby calculates the relative density of this solution.But this assay method exists certain problem, the one, pycnometer has liquid when taking out and overflows from water-bath, during with the paper wiping since many solution particularly Chinese medicine ointment have very high slumpability, be difficult to clean and adhere to a bottle outer wall.Another problem is that water purification and solution must use same pycnometer when carrying out the relative density measurement, after just the weight measurement of solution finishes, use the distilled water clean dry to constant weight pycnometer, and this process just needs a few hours.First problem can cause the accuracy measured, and second problem then can cause minute long, thereby influences job schedule, even causes the solution corruption.This in addition assay method is unsuitable for the mensuration of high density, high viscosity, high temperature, volatility and corrosive liquids.For the measurement of alcoholic strength, generally be to use alcohol meter, but alcohol meter can only be measured certain fixed temperature point, the fixing alcoholic strength of alcohol content scope, and degree of accuracy is relatively poor.For the measurement of pol, generally adopt saccharometer, but saccharometer can only be measured the pol of certain fixed temperature point, and degree of accuracy is relatively poor.For the measurement of fluid density, also there is not special-purpose instrument at present.
The purpose of this utility model provides a kind of multifunction electronic density instrument, can overcome relative density measure in pycnometer method be unsuitable for the shortcoming of high density, high viscosity, high temperature, volatility and corrosive liquid body measurement, overcome the deficiency in alcohol meter, the saccharometer use, realize that the instrumentation of fluid density is measured.Make a kind of device have the function of measuring fluid density, relative density, alcoholic strength, pol and solutes content simultaneously, and have the characteristics accurately quick, that measurement range is wide, usable range is wide.
The utility model comprises that electronic weighting equipment (electronic balance or electronics hang title), buoyancy aid and Support Level constitute.
The utility model is the buoyancy aid that hangs a known volume on electronic weighting equipment, and buoyancy aid is immersed in the testing liquid in the open-top receptacle, and electronic weighting equipment can be measured the changing value that buoyancy aid immerses quality before and after the liquid, the i.e. quality of the liquid that buoyancy aid arranged.Density of liquid be can draw with this changing value divided by the volume of buoyancy aid, and the relative density of liquid, the alcoholic strength of alcohol, the pol of liquid glucose and the content of other liquid solute drawn thus.Buoyancy aid adopts high density, high temperature resistant, corrosion resistant solid material, and the container of liquid adopts opened type, and this makes the utility model can be applicable to the mensuration of high density, high viscosity, high-temperature fluid simultaneously.Because electronic weighting equipment has the characteristic that weighing speed is fast, degree of accuracy is high, and the volume of buoyancy aid under different temperatures can draw according to thermal expansivity, makes the utility model also be suitable for the mensuration of the liquid of volatile liquid, different temperatures.
The utility model is described in detail as follows in conjunction with the accompanying drawings:
Fig. 1 is the structural representation that electronic balance is measured.
Fig. 2 is that electronics hangs the structural representation that claims mensuration.
As shown in the figure, when adopting electronic balance 1, see Fig. 1, device is made up of balance 1, buoyancy aid 2, Support Level 3 (Support Level 3 usefulness fibers or metal wire are made, and flexible, length is adjusted as required), hook 4, lateral frame 5 and perpendicular support 6, Support Level 3 connects buoyancy aid 2 and hangs on the hook 4, hook 4 is fixed on the lateral frame 5, and lateral frame 5 can serve as that axle rotates and can move up and down to erect support 6, and perpendicular support 6 connects with the shell of balance 1 or stands in by it.The common quality of testing liquid and container immerses buoyancy aid in the liquid then in the balance elder generation weighing container, weighing quality at this moment.The difference of twice weighing result is the quality of the liquid that buoyancy aid arranges, and the volume of buoyancy aid is known, can draw the alcoholic strength of density of liquid, relative density, alcohol, the pol of liquid glucose and the solutes content of other solution thus.
Adopt electronics to hang and claim at 7 o'clock, see Fig. 2, device claims 7 by hanging, buoyancy aid 2, Support Level 3 are formed, and Support Level 3 connects buoyancy aids 2 and hangs over and hang on the title 7.The quality of elder generation's weighing buoyancy aid immerses buoyancy aid 2 in the testing liquid then, the quality of weighing buoyancy aid this moment.The difference of twice weighing result is the quality of the liquid that buoyancy aid arranges, and the volume of buoyancy aid is known, can draw the alcoholic strength of density of liquid, relative density, alcohol, the pol of liquid glucose and the solutes content of other solution thus.
