The invention provides a device and a method for collecting micrometeorite from ice and snow, and belongs to meteorite collecting devices. The device and the method are used for collecting micrometeorite from a polar region. The device comprises supporting legs, wherein a main barrel is arranged on the supporting legs in a connection manner; a barrel body jacket is arranged on the sidewall of themain sleeve; a heater is mounted in the jacket; the barrel body jacket comprises a jacket water inlet and a jacket water outlet; a cover plate is mounted on the top part of the main barrel; a throughhole which is communicated with a filtering flushing hole net set is formed in the bottom part of the main barrel; the filtering punching hole net set comprises filtering layers which are arranged from top to bottom by layering, and the filtering nets are different in hole diameter; an outlet of the filtering punching hole net set is connected to an anti-explosion centrifugal pump through a discharging port control valve; a centrifugal pump discharging port is formed in the anti-explosion centrifugal pump, so that filtered snow water can be quickly drained; micrometeorite with different particle size can be intercepted and stopped on the filtering nets through a plurality of filtering layers with different hole diameters at the bottom part of the device, and the micrometeorite can be recovered.
Description
technical field [0001] The invention belongs to a meteorite collecting device, and relates to a device and a method for collecting micrometeorites in ice and snow in polar regions. Background technique [0002] Since the 21st century, people have generally defined extraterrestrial natural solid materials with a particle size of less than 2 mm and collected on the surface as micrometeorites. According to statistics, the total amount of extraterrestrial matter accreted by the earth every year is 4×114 tons, most of which are micrometeorites. As the key to understanding the solar system and even the interstellar space, the collection and research of micrometeorites has become a hot research field in astrochemistry and space science. Since the 1940s, the collection of micrometeorites has become an international hotspot. Especially after the 1980s, through the collection of micrometeorites in the north and south poles, a large number of scientific results have been produced. m...
