Abstract
The inventive method is a kind of coal petrography water absorption measuring method.The coal petrography water suction system for measuring quantity of this method includes: container, sample, high speed acquisition instrument, constant-current source, support, LOAD CELLS.Weight change in coal petrography water absorption course is converted into the signal of telecommunication mainly by LOAD CELLS by the present invention, obtains experimental result through high speed acquisition instrument collection and process.During experiment, LOAD CELLS is fixed on support, then ties up to sample, below LOAD CELLS, then connect with the mains, be connected into data collecting system, add water logging in a reservoir and do not have sample, just can start experiment.This method is relative to traditional method, more accurately, saves manpower, conveniently obtains mass data thus shown that conclusion is the most accurate.
Description
Technical field
The invention belongs to a kind of new method of testing of coal petrography water absorption experiment, be specifically related to a kind of novel mensuration coal petrography and inhale
The device of the water yield.
Background technology
At present, coal petrography is acted on by water the biggest application in engineering, so for coal petrography property in water absorption course
Matter feature needs to continue research, finds convenient method accurately to have important meaning.
The measurement of traditional coal petrography water absorption needs continuous wiping test specimen, and this can destroying infection experimental result to test specimen.
This experiment typically will continue 48h, it is desirable to have the continual taking-up from water by sample of people is weighed, and the data obtained have
, i.e. there is manpower waste and the shortcoming of experimental data deficiency in limit.Existing employing suspends the water suction artificial reading of scales/electronic balance weighing in midair
Method, relatively conventional method improves to some extent, but there are still manual read's number, need hermetic container prevent steam evaporation weightlessness
Impact.Along with the progress of science and technology, the application of automatization will be greatly improved the Accuracy and high efficiency of experiment, so needing
Current method is improved and innovates.
Summary of the invention
The invention discloses the way of a kind of novel measurement coal petrography water absorption.Utilize LOAD CELLS to measure sample to absorb water
Weight change in journey, high speed acquisition instrument carries out data collection and process, improves existing experimental technique.
The present invention takes techniques below scheme to realize this purpose: this experimental system mainly by container, sample, at a high speed
Acquisition Instrument, constant-current source, support, LOAD CELLS.Test specimen is hung on LOAD CELLS, then LOAD CELLS is fixed on support
On, then by placed in the vessel for sample, LOAD CELLS is connected constant-current source, then inputs a signal into data collecting system.Just
Can the most automatically gather the data of 48h.
Described coal petrography pipette measuring method, comprises the following steps:
Step one: polishing test specimen, understands surface contaminant；
Step 2: tied up to by test specimen on LOAD CELLS, is fixed on LOAD CELLS on support, test specimen is suspended in container
Centre, connects LOAD CELLS upper constant-current source, load cell signal finally accesses high speed acquisition instrument；
Step 3: whole device is put into narrow and small airtight space；
Step 4: open all appts, first gathers a period of time data；
Step 5: water will be added in container until flooding test specimen；
Step 6: experiment carry out 24h, after terminating by equipment institute image preserve, process data, experiment terminates；
Beneficial effects of the present invention:
1, the present invention is compared with traditional method, it is not necessary to expend substantial amounts of manpower, and equipment is good, can leave wait real
Test and terminate.
2, the present invention is compared with traditional method, it is not necessary to artificial reading, uses machine reading, more accurately..
3, the present invention is compared with traditional method, gathers data the most, and the experiment conclusion drawn has more science.
4, the present invention is compared with traditional method, and this experimental technique eliminates the impact of water evaporation, more rigorous.
5, the present invention is compared with traditional method, it is possible to measure multiple sample simultaneously, if the port number of data collecting system
Meeting, can gather the data of ten several to dozens of samples simultaneously, this is that existing traditional method is not accomplished.

Detailed description of the invention
Below in conjunction with accompanying drawing be embodied as case the inventive method is described in further detail.
As it is shown in figure 1, a kind of coal petrography capillary water absorption system for measuring quantity, described high speed acquisition instrument 1 stores for HIOKI 8842T
Monitor.Described support 2 height is 610mm.The range of described LOAD CELLS 3 is 0-1kg.Described sample 4 is diameter
The coal cinder of 50.10mm, highly 65.23mm.Described container 5 is the beaker of 1000ml.Constant-current source 6 can provide direct current 24V voltage.
Coal petrography water absorption measuring method described in employing, comprises the following steps:
Step one: polishing coal cinder test specimen, understands surface contaminant；
Step 2: tied up to by coal cinder on LOAD CELLS, is fixed on LOAD CELLS on support, is suspended in by test specimen
In the middle of the beaker of 1000ml, LOAD CELLS is connected upper constant-current source, makes constant-current source provide direct current 24V voltage, finally will weigh
Sensor signal access high speed acquisition instrument, regulation sampling rate be 2 per second；
Step 3: whole device is put in closet；
Step 4: open all appts, closes closet, first gathers a period of time data；
Step 5: water will be added in the beaker of 1000ml until flooding coal cinder；
Step 6: experiment carry out 24h, after terminating by equipment institute image preserve, data process, experiment terminates.
