Embodiment
The utility model proposes a kind of device of novel mensuration coal petrography water-intake rate, in order to make advantage of the present utility model, technical scheme clearly, clearly, below in conjunction with specific embodiment, explanation clear, complete further being done to the utility model.
Shown in composition graphs 1, the utility model, a kind of device of novel mensuration coal petrography water-intake rate, it comprises test bottle, with in prior art unlike, the utility model test bottle is Demountable, it comprises upper bottle body 1 and lower bottle body 3, upper bottle body 1 is for falling funnel-form, bottle mouth position is elongate column pipe, and upper bottle body 1 and lower bottle body 3 can, by the screw thread 2 row fitted seal arranged separately, seal more tight to make upper bottle body 1 and lower bottle body 3, the utility model is preferably provided with liner packing ring at screw thread place, and shape, the size of liner packing ring match with screw thread;
The coal rock specimen 6 of test is needed to be placed on objective table 4, the table top of objective table 4 is preferably stainless steel wire-grid structure, as shown in Figure 2, the table top of stainless steel wire-grid structure can make water fully contact with coal rock specimen 6, objective table 4 corner support supports, objective table 4 is installed on the water-proof sensor for recording test specimen weight, water-proof sensor by the mass transport of test specimen 6 that perceives to computing machine 7;
At the bottle mouth position of above-mentioned upper bottle body 1, namely colonnette tubular wall is carved with scale, can be used for measuring the height of water level in test bottle, the outboard tube at scale place is embedded with inductor 5, and the height of water level in the test bottle perceived is transferred to computing machine 7 by inductor 5.
The utility model device is in open environment, Evaporation Phenomenon can occur, because different temperatures, humidity are to evaporation of water system water difference, so should first record evaporation coefficient k per hour under uniform temperature humidity before experiment, such as formula (1),
The volume of ρ-----liquid,
The cross-sectional area of s-----upper bottle body,
----measure evaporation coefficient time initial water level, at the end of water level, surveyed by inductor 5,
N-----surveys hourage.
Then the quality of institute's absorbing fluid is measured:
M
water=(h
2-h
1) ρ gs-kn=Δ h ρ gs-kn (2)
H
1, h
2----measure institute's absorbing fluid quality time initial water level, at the end of water level.
Computing machine is by receiving the water-intake rate of data calculation testing piece by following formula:,
M
water, M
drybe respectively the quality of the quality of dropping liq, dry test specimen.
The method of testing of the utility model device:
Step 1, first pour suitable quantity of water into from the mouth of pipe and survey its evaporation coefficient k, then water is poured out;
Step 2, upper bottle body 1 to be unloaded down from lower bottle body 3, dried test specimen 6 is placed on objective table 4, by waterproof inductor by test specimen mass transport to counter 7;
Step 3, water is slowly poured into until do not have test specimen 6 along the cup wall of lower bottle body 3, then upper bottle body 2 is sealed on lower bottle body 3 by screw thread rotation, the scale tube wall side of water from upper bottle body 2 is slowly poured into, until fluid column reaches the scale mark upper limit, this process must slowly be poured into, reduce bubble to produce, now inductor 5 record liquid-column height h automatically as far as possible
1, and touch computing machine timer and start timing.
After step 4, timing start, every two hour records fluid column height and calculate
Δh＝(h
i-h
