Description

Rock sample/earth sample saturation device by chemical solution

Technical field

The present invention relates to a kind of rock sample/earth sample laboratory equipment, relate in particular to the rock sample/earth sample saturation device by chemical solution that a kind of laboratory is used.

Background technology

We can study the different conditions of rock sample/earth sample when rock sample/earth sample is studied usually, as the rock sample under the rock sample of drying, saturated fully rock sample, the different state of saturation with other of rock sample under the state of nature; Thereby obtain the performance parameter of rock sample/earth sample under the different conditions.

Rock sample is carried out saturated processing, dual mode is arranged in the laboratory:

First kind of mode is to utilize vacuum pump+irony sample storage container, and this container general water in the laboratory comes rock sample/earth sample is vacuumized saturated;

The second way is exactly directly to soak, and rock sample is placed directly in the water soaks until saturated.

The advantage of first kind of mode be can well rock sample/earth sample be carried out water or solution saturated, but that this kind device is not suitable for that rock sample is carried out chemical solution is saturated, because chemical solution corrodes the sample storage container easily, and corrodes vacuum pump more or less.Though it is saturated that the second way can be carried out rock sample chemistry, the time is short to be not easy saturatedly, because residual gas is difficult for discharging in the rock sample, wants saturatedly fully, in fact is difficult to realize.

Therefore, rock sample/earth sample is carried out the specific saturation device of the saturated needs of chemical solution.

Summary of the invention

Purpose of the present invention is intended to overcome the shortcoming and defect that prior art exists, provide a kind of can to rock mass/soil body carry out chemical solution saturated, to container unaffected, safe lab setup under the corrosivity condition, a kind of rock sample/earth sample saturation device by chemical solution promptly is provided.

The object of the present invention is achieved like this:

The present invention includes vacuum drying ware, vacuum meter, glass three interface shunts, first glass switch, second glass switch, the 3rd glass switch, vacuum pump, glass jar and grass tube;

The vacuum drying ware joins with first interface of vacuum meter and glass three interface shunts respectively, and second and third interface of glass three interface shunts joins with glass jar and vacuum pump respectively by grass tube;

First, second and third interface at glass three interface shunts is respectively arranged with first, second and third glass switch.

Principle of work of the present invention is:

At first will need saturated rock sample/earth sample to be put in the vacuum drying ware sets, then second glass switch is transferred to buttoned-up status, first glass switch and the 3rd glass switch are transferred to full-gear, open vacuum pump, reach setting until the reading of vacuum meter; Close vacuum pump, close the 3rd glass switch simultaneously; Open second glass switch again, the negative pressure of vacuum drying ware can absorb the chemical solution in the glass jar in the vacuum drying ware automatically, after chemical solution soaks rock sample/earth sample fully, close first glass switch and and second glass switch, saturated until rock sample/earth sample.

The present invention has following advantage and good effect:

1. it is saturated rock sample/earth sample to be carried out chemical solution, can prevent the corrosion of chemical solution to device.

2. carry out rock sample/earth sample saturated in, saturated polylith rock sample simultaneously, and the use amount of chemical solution is few, saves cost.

3. the vacuum tightness situation of finder inside at any time when vacuumizing exhausts and turns off all valves after vacuum sucks chemical solution, can make rock sample saturated more thoroughly, quick.

Be applicable to that water, the chemical solution to rock sample/earth sample is saturated in the laboratory.
