Description

Block ore density measurement device
Technical field
The utility model relates to a kind of density measurement device, particularly relates to the device for quick testing of profile irregular block ore density.
Background technology
When testing the density of solid, usually adopt " floating title method ", method the most frequently used in test density in the existing multiple ground method of testing standard of the method Ye Shi China, working specification.When claiming the quality of solid, weighing instrument generally adopts double plate mechanical balance, weighing precision is generally 0.01g, if adopt the mechanical analytic balance that precision is higher, its range of weighing, stability of equilibrium two aspect all do not meet actual needs, and when weighing, need repeated multiple times increase and decrease counterweight, can not reach balance rapidly, weighing is wasted time and energy, complex operation.
Electronic balance is all better than physical balance in range of weighing, precision, stability, efficiency etc., and has peeling Protection Counter Functions, but it only has the sensor under single-deck, directly can not measure the buoyancy upwards that solid is subject in a liquid.
Test the density of solid, also need the volume of solid mineral.According to Archimedes principle, can measure solid to be measured in water, overcome buoyancy after gravity or measure the buoyancy that solid is subject in water, then according to equilibrium of forces, and then try to achieve the volume of solid to be measured.Existing block ore device for detecting density, be all by measure block ore overcome in water after buoyancy gravity, calculate the volume of block ore, and the buoyancy be not subject in water by measuring block ore calculates the volume of block ore.In addition, existing there is complicated operation in block ore device for detecting density, precision is low, cost is high, or structure such as to simplify not at one or more problems.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of block ore density measurement device, block ore density measurement apparatus structure is simplified, error is little, cost is low for this, easy to operate, be easy to safeguard block ore density measurement device.
Test philosophy of the present utility model is: by measuring the buoyancy in a liquid of block ore to be measured, calculated the volume of block ore to be measured by Archimedes principle, then calculate its density in conjunction with block ore quality to be measured.
Block ore density measurement device of the present utility model comprises: electronic balance, cup, sample frame, support, connection cord, base, sample frame to be connected with support by connection cord and to be suspended from cup, support bottom is fixed on base, electronic balance is placed horizontally on base, and cup fills the liquid of submergence sample frame and is positioned on electronic balance.Sample frame, support, connection cord all directly do not contact with cup with electronic balance.
Further, described connection cord is rigidity cord.
Further, described electronic balance is that to have peeling Protection Counter Functions, precision be the electronic balance of 0.1mg; Further, the outside of block ore density measurement device also has a transparent cover.
Further, described liquid is water.
The beneficial effects of the utility model are: use electronic balance indirectly to measure block ore to be measured buoyancy in a liquid dexterously, obtain the volume of block ore to be measured fast, and then try to achieve its density; Block ore density measurement apparatus structure is simplified, and measuring accuracy is high, and cost is low, simple and quick and be convenient to safeguard.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of block ore density measurement device.
Parts title and numbering in figure: electronic balance 1, cup 2, sample frame 3, support 4, connection cord 5, base 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model " block ore density measurement device " comprising: electronic balance 1, cup 2, sample frame 3, support 4, connection cord 5, base 6, sample frame 3 to be connected with support 4 by connection cord 5 and to be suspended from cup 2, support 4 bottom is fixed on base 6, electronic balance 1 is placed horizontally on base 6, and cup 2 fills the liquid of submergence sample frame 3 and is positioned on electronic balance 1.
When carrying out block ore density measurement, first by electronic balance leveling, weighed by block ore to be measured, recording quality is m; Be placed in by cup 2 directly over electronic balance 1, adjusting pole 4 makes sample frame 3 not contact with cup 2 inwall, loads the water of energy submergence sample frame 3, reset after electronic balance 1 is stable in cup 2; Block ore to be measured is put into sample frame 3, the complete submergence sample of water, but must not overflow cup 2, it is V that electronic balance 1 shows reading.Ignore the volume of cup 2 liquid level rising submergence connection cord 5, namely this reading V is the quality of the water equal with block ore volume to be measured, according to the density of water, can try to achieve the volume of block ore to be measured.The density of water intaking is 1.00g/cm 3, numerically V is exactly the volume of block ore to be measured, directly just obtains the density of block ore to be measured fast divided by V according to m.
Be less than the density of the block ore of described liquid in order to test density, select connection cord 5 for rigidity cord, to ensure that block ore to be measured and sample frame 3 are in test process, can be immersed in liquid completely.
Electronic balance 1 can select that precision is 0.01g, precision is 0.001g, precision is the balances such as 0.0001g, in order to test data accurately with stable, avoid the impact that air flows, the outside of block ore density measurement device is also provided with translucent cover.In clearing with when weighing, close cover, avoid the impact that air flows, improve measuring accuracy.
Described liquid is the medium of test volume, is preferably water, also can be the known oil, aqueous solution etc. of density, with block ore to be measured, other homogeneous liquids of any physicochemical change or reaction not occur.Proving installation method is consistent with above-described embodiment, and the difference of computing method is the density selecting this homogeneous liquid when calculating block ore volume to be measured.
In order to improve the precision of block ore density measurement device, by the temperature of test liquid, liquid density at different temperatures can also being corrected, such as, by measuring the temperature of water, accurate correction being carried out to water density at different temperatures.When needs Fast Measurement block ore to be measured density, and when not needing too high accuracy requirement, m can be directly adopted to calculate the density of block ore to be measured divided by V.
The utility model is not only applicable to the density of test block body ore, is also applicable to the test of other density of solid.
