Embodiment

[0027] Example An extraction device for polychlorinated biphenyl-containing soil analysis

[0028] This embodiment discloses an extraction device for soil analysis containing polychlorinated biphenyls, such as figure 1 As shown, it includes a cylindrical structure for containing soil, a driving and cutting mechanism hinged at the lower end of the cylindrical structure, and an end cap 4 for sealing the upper end of the cylindrical structure.

[0029] Among them, in order to facilitate the layered sampling of the soil in the cylindrical structure, such as figure 1 As shown, the cylindrical structure is composed of a plurality of sequentially stacked sleeves 1, and a sleeve 6 is cast at a corresponding position on the outer wall of each sleeve 1, and each sleeve 6 is sequentially worn from top to bottom. The rotating shafts 5 of the shaft sleeves 6 are connected together, and the upper part of the rotating shaft 5 is threaded with a first locking bolt, and a locking mechanism 8 ...

Abstract

The invention discloses an extraction device applied to analysis of soil including polychlorinated biphenyl. The device comprises multiple sleeves stacked to form a tubular structure; the multiple sleeves are rotationally connected with a rotation shaft, a locking mechanism is arranged between the two adjacent sleeves, and a tunneling cutting mechanism is hinged to the sleeves; during the processthat soil is extracted into the tubular structure, each locking mechanism separately locks the corresponding two adjacent sleeves; when the soil in the tubular structure is extracted per layers, the locking mechanism releases the locking of the two corresponding sleeves, and the sleeves rotate along the rotation shaft under the driving of an external force to be distributed in a staggered manner,so that the soil in each sleeve rotates along with the corresponding sleeve, and thus separation of the soil in adjacent sleeves is achieved. The device provided by the invention has the characteristics of being accurate in layered soil sample extraction and checking, convenient to operate, and capable of reducing the working strength of operating personnel, and is applicable to the technical field of analysis of the soil including the polychlorinated biphenyl.

Description

technical field [0001] The invention belongs to the technical field of polychlorinated biphenyl-containing soil analysis, and in particular relates to an extraction device for polychlorinated biphenyl-containing soil analysis. Background technique [0002] The English name of polychlorinated biphenyls: Polychlorinated biphenyls, polychlorinated biphenyls are carcinogens, easy to accumulate in adipose tissue, causing diseases of the brain, skin and internal organs, and affecting the nervous, reproductive and immune systems. The chemical properties of polychlorinated biphenyls are very stable and difficult to decompose in nature. They belong to the category of persistent organic pollutants and are mostly used in electrical equipment, such as capacitors and transformers containing polychlorinated biphenyls. At present, most electrical equipment containing PCBs are piled up at designated locations to wait for centralized treatment. However, the soil where the power equipment ha...
