Rock sample/soil sample chemical solution saturation device

Abstract

The invention discloses a rock sample / soil sample chemical solution saturation device, and relates to rock sample / soil sample laboratory equipment. The structure of the present invention is: the vacuum drying dish (1) is respectively connected with the first interface of the vacuum gauge (2) and the glass three-interface shunt (3), and the second and third interfaces of the glass three-interface shunt (3) pass through The glass conduit (9) is connected with the glass tank (8) and the vacuum pump (7) respectively; the first, second and third glass switches ( 4, 5, 6). The invention can prevent the chemical solution from corroding the device; it can saturate multiple rock samples at the same time, and the use of chemical solution is small, saving costs; the vacuum degree inside the device can be observed at any time during vacuuming, and the chemical inhalation is completed after vacuuming. Turn off all the valves after the solution, which can make the rock sample saturated more thoroughly and quickly; it is suitable for the water and chemical solution saturation of rock samples / soil samples in the laboratory.

Description

technical field [0001] The invention relates to a rock sample / soil sample laboratory equipment, in particular to a rock sample / soil sample chemical solution saturation device for the laboratory. Background technique [0002] When we study rock samples / soil samples, we usually study different states of rock samples / soil samples, such as dry rock samples, fully saturated rock samples, natural rock samples and other saturated states Under the rock sample; thus obtain the performance parameters of the rock sample / soil sample in different states. [0003] There are two ways to saturate rock samples in the laboratory: [0004] The first way is to use a vacuum pump + iron sample storage container, which is usually used to vacuum and saturate the rock sample / soil sample with water in the laboratory; [0005] The second way is direct immersion, where the rock sample is soaked directly in water until saturated. [0006] The advantage of the first method is that it can well saturate...

AI Technical Summary

Problems solved by technology

[0006] The advantage of the first method is that it can well saturate the rock sample / soil sample with water or solution, but this kind of device is not suitable for saturating the rock sample with chemical solution, because the chemical solution is easy to corrode the sample storage container, and more or less Corrosion-less vacuum pump

Although the second method can chemically saturate the rock sample, it takes a short time and is not easy to saturate. Because the residual gas in the rock sample is not easy to discharge, it is actually difficult to achieve complete saturation.
