Portable water body heavy metal detection device

Abstract

The invention relates to the technical field of metal detection, and discloses a portable water body heavy metal detection device. The portable water body heavy metal detection device comprises two air bags and a box body, the air bags are symmetric with the box body as a center, arc blocks are fixedly installed at the tops of the air bags, fixing frames are fixedly connected to the upper surfacesof the arc blocks, and the air bags are connected with the box body through the arc blocks and the fixing frames. Compared with the prior art, the magnitude of buoyancy of the device in a water bodyis changed through the volume change of the air bags in water, so that the detection depth of the air bags in a polluted water body is adjusted; and meanwhile, by arranging a power device, thrust is provided for the device, the detection range of the device is increased, the air bags and the power device cooperate with each other, so that the device performs online detection at any place of the polluted water body, the sample sampling time is shortened, the detection efficiency is effectively improved, the number of detection is increased, so that more detection data are obtained, comparison is effectively formed, and the detection precision is increased.

technical field [0001] The invention relates to the technical field of metal detection, in particular to a portable water heavy metal detection device. Background technique [0002] Pollution is an environmental problem on a global scale, and the mining industry is one of the most serious sources of heavy metal pollution. At the same time, most mining areas use heap leaching to extract metal minerals from low-grade ores. And the environmental protection measures are uneven, the degree of supervision is poor, and the leakage of heap leaching solution often occurs in heap leaching sites. These sewage often contain heavy metal content of hundreds to thousands of ppm. At present, the quantitative analysis of water pollution mainly relies on laboratories Methods, such as X-ray absorption spectrometry, atomic absorption spectrometry, plasma mass spectrometry, ion chromatography-inductively coupled plasma mass spectrometry, and inductively coupled plasma emission spectrometry, etc....

[0002] Pollution is an environmental problem on a global scale, and the mining industry is one of the most serious sources of heavy metal pollution. At the same time, most mining areas use heap leaching to extract metal minerals from low-grade ores. And the environmental protection measures are uneven, the degree of supervision is poor, and the leakage of heap leaching solution often occurs in heap leaching sites. These sewage often contain heavy metal content of hundreds to thousands of ppm. At present, the quantitative analysis of water pollution mainly relies on laboratories Methods, such as X-ray absorption spectrometry, atomic absorption spectrometry, plasma mass spectrometry, ion chromatography-inductively coupled plasma mass spectrometry, and inductively coupled plasma emission spectrometry, etc., but these methods require sample collection and preparation, which not only It is not economical and wastes time. In this way, on-site detection can be carried out by using a handheld X-ray fluorescence instrument, but there are some shortcomings in the handheld X-ray fluorescence instrument for water pollution detection, as follows:

[0003] When using a hand-held X-ray fluorescence instrument to detect water pollutants, because it needs to be manually controlled by hand, the detection range is limited to the surrounding of the polluted water body, and the detection needs to stabilize the equipment for a period of time, so the requirements for operators are relatively high. At the same time, the liquid will cause damage to the hand-held X-ray fluorescence instrument, and the hand-held X-ray fluorescence instrument needs to be protected. In this case, it is still necessary to extract samples on site, and then perform testing according to the testing procedures in the laboratory, and the detection efficiency is still insufficient.
