Liquid sample collecting device based on geochemical engineering

Abstract

The invention provides a liquid sample collecting device based on geochemical engineering, and relates to the technical field of geochemistry, the liquid sample collecting device comprises a base, the upper surface of the base is fixedly provided with a supporting seat, one end of the upper surface of the supporting seat is provided with a sampling driving mechanism, and the sampling driving mechanism comprises a sealing pipe; the sealing pipe is fixedly installed on the upper surface of the supporting base, a collecting mechanism is installed on the side, located on the sealing pipe, of the supporting base and comprises a collecting tank, a feeding pipe is integrally arranged at the lower end of the collecting tank, and a discharging pipe is integrally arranged on the outer wall of the lower end of the collecting tank; the movable seat main body is moved to different positions, so that the positioning cylinders are clamped in the positioning grooves at different positions, and the hollow shaft can inject samples into a plurality of sample tanks for experiments by controlling the movable seat main body to move, so that the operation difficulty is reduced, and the phenomenon that the samples are scattered during injection is avoided.

Description

technical field [0001] The invention relates to the technical field of geochemistry, in particular to a liquid sample collection device based on geochemical engineering. Background technique [0002] Geochemistry is a discipline that studies the chemical composition and evolution of the earth and its subsystems (including some cosmic bodies). It mainly studies the chemical composition of the earth (including some celestial bodies); it is a discipline that studies the mechanism and conditions of chemical action in geological processes, the symbiotic combination of elements and their occurrence forms, and the migration and circulation of elements, etc. Liquid samples are often used in geochemical research For detection and analysis, when collecting liquid samples, the liquid samples should be collected by the collection device, such as a liquid collection device for geochemical sample detection proposed by the patent application number CN202022151914.1, including: collection b...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a liquid sample collection device based on geochemical engineering, which solves the problem that it is difficult to determine the accuracy of the data due to a single experiment. When the above scheme is used, the detected samples cannot be separated Inject into multiple access tubes for experiments, which is not convenient for staff to use
