Description
Technical field
The present invention relates to density of solid detection technique field, relate in particular to method and the device of density of solid detection.
Background technology
The rough detection of usual density of solid is with weighing sample quality m, calculation sample volume V, then calculates density p.But be just difficult to accurately calculate volume V for object in irregular shape, the fruit density ρ thus calculated is rough, coarse.Also use drainage measurement volumes V instead, but during binding sample, easy contaminated samples causes precise decreasing, the solid sample of bubbling through the water column when running into detection measures trouble more.If give professional institution to detect, the time expended is long again.Thus, method and device thereof that a kind of not only easy but also accurate density of solid detects is necessary to research and develop.
Summary of the invention
The technical problem to be solved in the present invention is to provide the method and device thereof that a kind of not only easy but also accurate density of solid detects.
For solving the problems of the technologies described above adopted technical scheme: a kind of detection method of density of solid, includes following steps: standby one can support or press against the special-shaped counterweight in solid to be measured immersion liquid, and counterweight has known volume V

Adopt a pick-up unit for the density of solid of said method, it is characterized in that: include title, carrying liquid container and point to be separated with the special-shaped counterweight of epicoele and cavity of resorption, wherein offer intercommunicating pore between the epicoele of counterweight and cavity of resorption.
On the basis of the above, described in be called that electronic pallet claims, container is fixed on the electronic pallet side of being much of, and the pallet that electronic pallet claims is fixed with the suspension bracket lifting special-shaped counterweight.
Adopt the beneficial effect that brings of the present invention: the present invention only need weigh the quality of solid to be measured and special-shaped counterweight immerses the weight in liquid together with solid to be measured, just accurately calculate the density of solid to be measured by formula, and the device realizing the method is simply formed primarily of title, container and special-shaped counterweight.It is not only easy but also accurate that visible employing the present invention measures density of solid, can realize the on-the-spot density accurately measuring solid sample fast.

As shown in Figure 1, for realizing the pick-up unit of the density of solid that said method adopts, include title 1, carrying liquid container 2 and point to be separated with the special-shaped counterweight 3 of epicoele 31 and cavity of resorption 32, wherein offer intercommunicating pore 33 between the epicoele 31 of counterweight 3 and cavity of resorption 32.
Preferably, described title 1 claims for electronic pallet, and container 2 is fixed on the electronic pallet side of being much of, and the pallet 11 that electronic pallet claims is fixed with the suspension bracket 4 lifting special-shaped counterweight 3.Container 2 does not contact pallet 11, and suspension bracket 4 can across above container 2.Profiled weight 3 is known quality, the solid not infiltrating liquid of volume, can be metal material, inorganic material, organic material etc.Utilize the counterweight density of different materials to be greater than liquid or be less than the method that liquid carrys out range extension.(range as electronic scale is 100 grams, and precision is 0.0001 gram, survey the density of the copper piece of 60 grams, the aluminium counterweight selecting density little, make copper piece and weights buoyancy in a liquid and weight counteracting part, jointly the pulling force of messenger wire is minimized, thus range extension).
When the density of solid 5 to be measured is greater than the density of liquid 6, solid 5 to be measured is placed on the epicoele 31 of special-shaped counterweight 3, and solid 5 to be measured can enter in liquid together with special-shaped counterweight 3; When the density of solid 5 to be measured is less than the density of liquid 6, solid 5 to be measured is placed on the cavity of resorption 32 of special-shaped counterweight 3, and solid 5 to be measured can be press against by special-shaped counterweight 3 and enter in liquid together.
During measurement, only need weigh the quality m of solid 5 to be measured
2to immerse the weight m in liquid together with solid 5 to be measured with special-shaped counterweight 3
3, then through type ρ
guaccurately calculate the density of solid 5 to be measured, to realize the on-the-spot density accurately measuring solid sample fast.
The pick-up unit of density of solid of the present invention not only accurately can measure density of solid, also accurately can measure the device of unknown liquid (as ceramic mud, industrial waste water etc.) proportion.Counterweight is immersed entirely in unknown liquid, the proportion of unknown liquid after weighing, can be calculated.
