Sample storage device for geological mineral exploration

Abstract

The invention discloses a sample storage device for geological mineral exploration and belongs to the field of sample storage, after flowing samples are stored, the interior of the sample storage device for geological mineral exploration can be vacuumized, the samples are effectively prevented from being oxidized, meanwhile, through the arrangement of a secondary sealing plate, the secondary sealing plate is inflated firstly, and then the flowing samples are stored in the sample storage device for geological mineral exploration. The pre-falling cushion balls fall off from the secondary sealing plate, then deflation is carried out, the secondary sealing plate is moved into the shell, the pre-falling cushion balls form an air cushion layer on the liquid level of the sample as the secondary sealing plate approaches the liquid level of the sample, and when the pre-falling cushion balls make contact with the surface of the secondary sealing plate, inflation continues to be carried out, so that the secondary sealing plate is tightly attached to the inner wall of the shell; compared with the prior art, the effect of adaptively setting the sealing position according to the sample amount can be realized, so that the wall hanging phenomenon is greatly reduced, the problem of non-uniform water content distribution of the sample is effectively avoided, and the accuracy of research data is further improved.

Description

technical field [0001] The invention relates to the field of sample storage, in particular to a sample storage device for geological and mineral exploration. Background technique [0002] Geological exploration can be understood as geological work in a broad sense. It is based on the needs of economic construction, national defense construction, and scientific and technological development, using geological exploration methods such as surveying and mapping, geophysical prospecting, geochemical prospecting, drilling, pit exploration, sampling testing, and geological remote sensing. , Investigation and research work on geological conditions such as rocks, stratum structures, minerals, groundwater, and landforms in a certain area. In a narrow sense, in the actual geological work in China, the geological exploration work is also divided into five stages, namely, regional geological survey, general survey, detailed survey, exploration and development exploration. During the geolo...

Problems solved by technology

[0006]Aiming at the problems existing in the prior art, the object of the present invention is to provide a sample storage device for geological and mineral exploration, after storing the flow samples, the internal Carry out vacuum treatment to effectively prevent the sample from being oxidized. At the same time, through the setting of the secondary sealing plate, first inflate the air into the secondary sealing plate to make multiple pre-falling air cushion balls fall off the secondary sealing plate, then deflate and place The secondary sealing plate moves to the inside of the housing. As it approaches the sample liquid surface, multiple pre-falling air cushion balls form a layer of air cushion layer on the sample liquid surface. When the pre-falling air cushion balls are in contact with the surface of the secondary sealing plate, they continue to inflate , so that the secondary sealing plate is closely attached to the inner wall of the shell, so as to realize the secondary sealing in the shell. Compared with the existing technology, the effect of setting the sealing position according to the adaptability of the sample volume can be realized, thereby greatly reducing the phenomenon of hanging on the wall , to effectively avoid the problem of uneven distribution of water content in samples, thereby improving the accuracy of research data
