Description
Technical field
The utility model relates to the solid density measuring device for solid materials of a kind of arbitrary shape, especially density is less than to 1g/cm
3solid matter carry out density measure.Specifically adopt LOAD CELLS and data acquisition and data processing technique to measuring such as the density of the solid matters such as ore.
Background technology
Density is a very important physical quantity, and there is important value in a lot of fields.For the density of measuring solid matter, there are a variety of metering systems, for example radioactivity principle mensuration, microwave technology mensuration and Archimedes's mensuration.Relatively more conventional is Archimedes's indirect method of measurement, but the Density Measuring Instrument based on this principle manufacture carries inconvenience mostly, measures inconvenient.
According to density calculation formula:
, key will be measured quality and the volume of solid matter accurately.For the mensuration of solid masses, can measure by LOAD CELLS in the market, and for the volume of irregular solid matter, cannot directly record, be generally to adopt the method for direct discharging liquid to measure.And the disclosed exhaust method of CN2533465Y penetron, due to complex structure, can not be realized portable measurement.Therefore can only be limited to laboratory measurement.The high precision density detector that CN2293826Y announces needs the devices of weighing such as pallet and counterweight, does not also have portable characteristic, and needs vernier reading, does not possess the advantage that digitizing shows.Deliver on Physical Experiment journal one piece paper that is entitled as < < intelligence density tester > > adopt sensor and the A/D module identical with the utility model, but the difference due to measuring principle, described in this piece of paper, surveying instrument volume is large, carrying still inconvenience, is to be also only suitable for laboratory measurement.
Summary of the invention
The purpose of this utility model is just to overcome above-mentioned the deficiencies in the prior art, and a kind of portable Portable solid penetron is provided.
The purpose of this utility model is achieved through the following technical solutions:
Portable solid penetron, by solid matter container 1 and airtight water container 2 are housed on container cushion cap, between solid matter container 1 and airtight water container 2, by flexible conduit 3, be communicated with, the first LOAD CELLS 4 is equipped with in solid matter container 1 bottom, the second LOAD CELLS 5, the first LOAD CELLS 4 are equipped with in airtight water container 2 bottoms and the second LOAD CELLS 5 connects and composes with metering circuit 13 respectively.
Metering circuit 13 is through amplifying circuit 6, A/D change-over circuit 7 and single-chip minimum system 8, to be connected and composed respectively with keyboard 10 and liquid crystal display 9 respectively by the first LOAD CELLS 4 and the second LOAD CELLS 5.The output signal access metering circuit of two-way LOAD CELLS is carried out data acquisition and processing (DAP).
Beneficial effect:
The utility model discloses a kind of variation of passing through to detect quality in fixed container, indirectly record the size of solid matter volume, and then try to achieve the device of tested solid matter density.The remarkable advantage of this device is to survey in extensive range, can be greater than 1g/cm to density
3and the density of solid matter not soluble in water is measured, greatly improved measuring accuracy.And LOAD CELLS object is to measure the phase difference of quality, the difference because of the quality that is filled with water in two containers does not produce error.In the metering circuit of gravity, adopted the integrated circuit of amplification and analog to digital conversion one.This device once completes on measuring, and has avoided repeatedly measuring the error accumulation causing.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Portable solid penetron, solid matter container 1 and the airtight water container 2 being communicated with by flexible conduit 3 by being equipped with on container cushion cap, the first LOAD CELLS 4 is equipped with in solid matter container 1 bottom, the second LOAD CELLS 5, the first LOAD CELLS 4 are equipped with in airtight water container 2 bottoms and the second LOAD CELLS 5 connects and composes with metering circuit 13 respectively.
Metering circuit 13 is through amplifying circuit 6, A/D change-over circuit 7 and single-chip minimum system 8, to be connected and composed respectively with keyboard 10 and liquid crystal display 9 respectively by the first LOAD CELLS 4 and the second LOAD CELLS 5.The output signal access metering circuit of two-way LOAD CELLS is carried out data acquisition and processing (DAP).
This physical quantity of density is defined as the ratio of quality m and volume v, and the physical quantity that needs thus to measure just has quality m and the volume v of measured object, and wherein trying to achieve of quality m can be realized by the higher LOAD CELLS of precision.As shown in Figure 1, before measured object is put into container 1, by the start key on lower keyboard 10, measure for the first time, the quality that now the first LOAD CELLS records is designated as m
1, the quality that the second LOAD CELLS records is designated as m
2; Then put into measured object in container 1, treat that measured object sinks to container bottom, by the end key on lower keyboard 10, the quality that now the first LOAD CELLS records is designated as
m'
1, second weighs
The quality that sensor records is designated as m '
2, by formula
(4) just can calculate the density of measured object.
Metering circuit 13 is to consist of the special-purpose A/D module 11 of HX711 LOAD CELLS and single-chip minimum system 8 and display 9 and keyboard 10.Wherein HX711 module 11 is integrated amplifying circuit 6 and the A/D change-over circuit 7 up to 24, has improved measuring accuracy greatly.
Two sensors of the utility model, one is the first LOAD CELLS 4 for xylometer 1 mass change amount, another is for measuring the LOAD CELLS 5 of the quality of water in airtight water container 2.While not putting into measured object in container 1, the container 1 that the first LOAD CELLS 4 records and the quality self being filled with water are m
1, the container 2 that the second LOAD CELLS 5 is measured and the quality self being filled with water are m
2; Measured object is put into container 1 container 1 that the first LOAD CELLS records afterwards and self is filled with water with the quality of measured object is m
1', the measured quality that obtains container 2 and self be filled with water of the second LOAD CELLS is m '
2, measured object quality is:
M＝(m′
1-m
1)+(m′
2-m
2)＝Δm
1+Δm
2

According to law of connected vessels, the volume of the water increasing in container 2 is the same with the volume that liquid level in container 1 rises, so the volume of measured object is:
The density that is obtained measured object by formula (1) and (2) is:
Because the density of water is known as 1g/cm
3so (3) formula can be reduced to:
By formula (4), can find out, by two LOAD CELLS, record the variation that measured object is put into front and back two container mass, just can obtain the density of measured object.
