Annularly-sealed liquid sampling device and method for chemical detection

Abstract

The invention discloses an annularly-sealed liquid sampling device and method for chemical detection. The device comprises a sampling protection cylinder and a sampling cylinder body, wherein the sampling protection cylinder is connected with the sampling cylinder body in a sleeving mode, a cylinder bottom plate is arranged at the lower end of the sampling protection cylinder, movable holes are formed in the side wall, close to the lower end, of the sampling protection cylinder at equal intervals, position limiting rings are connected into the movable holes in a penetrating mode, and limitingsupporting frames are connected into the movable holes in a penetrating mode. According to the annularly-sealed liquid sampling device and method for chemical detection, a sampling protection cylinderis connected with a sampling cylinder body in a sleeving mode, a telescopic protection cover is fixedly connected to the outer wall of the upper end of the sampling cylinder body, and the sampling cylinder body is wrapped with the sampling protection cylinder and the telescopic protection cover, so that the problem that liquid adhering to the surface of the sampling barrel body drips after sampling can be solved, the environment is protected, pollution is prevented, and meanwhile sampled liquid in the sampling barrel body is not prone to being polluted by the outside.

Description

technical field [0001] The invention relates to the technical field of chemical detection instruments, in particular to an annular sealable liquid sampling device and method for chemical detection. Background technique [0002] Chemical sampling refers to the sampling work for determining the chemical composition and content of the ore body and its surrounding rock, the products produced by the mine (such as raw ore, concentrate), tailings, waste rock, and rocks related to minerals. It includes chemical samples The whole process of sampling work such as collection, processing, analysis and quality inspection, chemical sampling in production mines is mainly carried out in underground tunnels, open pit or underground stopes and mined ore. The sampling device is a device for taking samples. In chemical experiments, it is often necessary to sample and test raw materials or reaction liquids. However, the existing samplers do not have the function of quantitative sampling. If the ...

Problems solved by technology

[0004] Although this application solves the problems in the background technology to a certain extent, the outer surface of the sampling shell after sampling in this application is sticky liquid, which is easy to pollute the environment and is inconvenient to move, especially after sampling outside, it needs to be taken to the laboratory, etc. When testing in an environment, it is easy to apply pressure to the operation panel, causing the sampled liquid to leak out, and when the operation panel is rotated, holding the sampling shell by hand is easy to cause the position of the sampling shell to move, especially for stratified liquids, which cannot control the sampling well liquid position
