Rotational flow sampler with replaceable wear-resistant lining

Abstract

The invention relates to the field of mineral exploration drilling sampling equipment, in particular to a rotational flow sampler with a replaceable wear-resistant lining, which comprises a cylinder body, a slag inlet channel, a cone, a slag outlet, an exhaust pipe and a ceramic splicing piece, wherein the slag inlet channel is communicated with the interior of the cylinder body and used for introducing a rock sample carrying airflow into the cylinder body, and a slag inlet is formed in the end, away from the cylinder body, of the slag inlet channel; the cone is communicated with the interiorof the cylinder body, is arranged at the bottom of the cylinder body and is used for transporting the solid rock sample subjected to solid-gas separation; the slag outlet is formed in one end, far away from the cylinder body, of the cone and is used for discharging the solid rock sample subjected to solid-gas separation; the exhaust pipe is communicated with the interior of the cylinder body, is arranged at the top of the cylinder body and is used for conveying gas subjected to solid-gas separation; the ceramic splicing piece is attached to the inner walls of the cylinder body and the slag inlet channel in a covering mode and formed by splicing ceramic pieces one by one, and the inner walls of the ceramic piece cylinder body and the slag inlet channel are detachably connected. The wear-resisting replaceable low-adhesion lining wall is used for achieving the effects that the inner cylinder wall of the rotational flow sampler is not damaged forever, and a rock sample is not likely to adhere to the inner cylinder wall of the rotational flow sampler.

Description

technical field [0001] The invention relates to the field of drilling and sampling equipment for mineral exploration, in particular to a swirl sampler with a replaceable wear-resistant lining. Background technique [0002] Air reverse circulation sampling technology drilling is a drilling technology aimed at obtaining high-quality cuttings samples continuously and efficiently. It is an important drilling technology to achieve a rapid and economical prospecting strategy. representative. Whether the drilling method of air reverse circulation sampling technology can obtain representative and most reliable sampling results is the only criterion to determine whether this technology can be applied to the field of mineral exploration. [0003] After 30 years of development in my country, air reverse circulation sampling technology has not been widely used in the field of mineral exploration. Among them, the immaturity of rock sample collection machinery and equipment suitable for ...
