Electric ice scraping device for ice core pretreatment

Abstract

The invention is an electric ice scraping device used for ice core pre-treatment, which is characterized by: the handle is connected to a carbon steel cutter head set or an alumina\ceramic cutter head set, a carbon steel cutter head set or an alumina\ceramic cutter head set. Place it in the cylindrical ice chip collection box through the extension hole of the ice chip collection box, in contact with the ice sample. The two sides of the ice chip collection box are connected by No. 1 hinges and No. 2 hinges. The two sides of the ice chip collection box are connected with hinges. There is a Reach into the hole. The invention is easy to assemble and disassemble, has improved uniformity and efficiency compared with manual ice scraping, saves manpower, material resources and time, has lower production cost, and is suitable for outer wall peeling of ice core pre-processing. This invention effectively avoids long-term exposure of ice samples in the air and greatly reduces possible secondary pollution in the air.

Description

technical field [0001] The invention belongs to the field of machinery, and specifically refers to an efficient and pollution-free electric ice scraping device used in the pretreatment of ice core research. Background technique [0002] Ice core records have the characteristics of good fidelity (low temperature environment), high resolution (up to one year), long record sequence (up to hundreds of thousands of years) and large amount of information. important research tool. Ice core climate records can make up for the shortage of meteorological stations in mountainous areas, their uneven distribution and the short period of data accumulation. At the same time, physical, chemical, and biological information can also be extracted from ice cores. These records preserve high-resolution paleoenvironmental signals, which can be used to test the influence of climate forcing factors (such as greenhouse gases and solar activities), and provide information on the impact of atmospheri...

AI Technical Summary

Problems solved by technology

Ice samples have been exposed to the air for a long time, and the environment is different from the glacier area, which may increase the probability of secondary pollution of the ice core and is not conducive to its preservation

At the same time, it is difficult to grasp the uniformity of sample peeling with artificial ice shaving. The repeated contact of the ice scraper (scalpel or ceramic knife) with the test bench will cause damage to the blade, and the consumption of materials is large. Manual ice shaving is time-consuming and labor-intensive. This slows down the progress of ice core processing and analysis, and also increases the cost of ice core research.

In addition, working in the ice storage for a long time will cause great harm to the staff
