Embodiment Construction

[0028] The present invention will be further elaborated and illustrated below in conjunction with the accompanying drawings and specific embodiments. The technical features of the various implementations in the present invention can be combined accordingly on the premise that there is no conflict with each other.

[0029] like figure 1 As shown, a spiral double-pipe tailings slag sampling device in this embodiment mainly includes two parts: an outer pipe 1 and an inner pipe 2 .

[0030] like figure 2 As shown, the main body of the outer tube 1 is a hollow cylindrical outer tube body 1.1, and a "one"-shaped handle 1.3 is fixed on the outside of the upper end of the outer tube body 1.1, and the "one"-shaped handle 1.3 is rigid to the outer tube body 1.1. Fixed, and the "one"-shaped handle 1.3 is respectively provided with outer tube fixing holes 1.4 on both sides of the outer tube body 1.1, and the outer tube fixing holes 1.4 can be through holes or slotted holes. Each outer...

Abstract

The invention discloses a helical dual-tube tailing area slag sampling device and a method thereof. The sampling device comprises an outer tube and an inner tube, wherein the outer tube main body is an outer tube body; an outer wall of the outer tube body is provided with a thread; an outer side of an upper part of the outer tube body is provided with a beeline handle; the beeline handle is provided with an outer tube fixing hole, and matched with an L-shaped fixing bolt; a lower part of the outer tube body is provided with a sampling door opening and a conical head; the inner tube main body is an inner tube body; an outer side of an upper part of the inner tube body is provided with a cross-shaped handle; the cross-shaped handle is provided with an inner tube fixing hole; the side edge ofthe lower part of the inner tube body is provided with a sampling door; and the sampling door is connected with the inner tube body through a spring hinge. The helical dual-tube tailing area slag sampling device has the advantages of simple structure, low cost, durability, convenience in carrying, high sampling efficiency, wide applicability and the like.

Description

technical field [0001] The invention belongs to the field of sample collection equipment, and in particular relates to a spiral double-pipe tailings slag sampling device and a method thereof. Background technique [0002] Tailings slag mainly refers to the residual waste generated in the process of ore dressing or smelting, and these wastes are usually disposed of through tailings piles and tailings ponds. Tailings slag contains a large amount of heavy metals and other toxic and harmful substances. Its long-term accumulation has caused serious pollution to the surrounding air, soil, surface water, and groundwater, endangering surrounding residents and ecosystems. Collecting slag samples at different depths and studying slag particle size distribution, composition, rock and soil mechanical properties, and heavy metal leaching performance play an important role in the control and treatment of tailings slag pollution. [0003] The traditional slag sampler, on the one hand, is ...
