Impurity separation and recovery system for exploration coring engineering

Abstract

The invention discloses an impurity separation and recovery system for exploration coring engineering. The impurity separation and recovery system comprises an interface device which is sleeved on a drill rod and a casing, connected with the top of the casing and used for recovering solid-liquid-gas substances generated during drilling, a recovery separator which is communicated with the interfacedevice through a pipeline and used for separating gaseous substances from solid-liquid substances, and a dust collecting device which is communicated with the recovery separator through a pipeline. According to the impurity separation and recovery system provided by the invention, through the accurate design of the interface device, the interface device can be perfectly matched with the drill rodand the casing, so that various solid-liquid-gas mixed substances generated during exploration coring are accurately and completely recovered, diffusion, environmental pollution and influence on thehealth of operators are avoided, impurities such as water, sediment and dust in the mixture are removed through double treatment of separation and filtration in sequence, and clean gas is finally discharged; and the whole system is simple, convenient to use and simple to operate, and is very suitable for application in exploration coring engineering.

Description

technical field [0001] The invention relates to the fields of exploration technology and environmental protection technology, in particular to a sundry separation and recovery system for exploration and coring engineering. Background technique [0002] Railway engineering survey occupies a very important position in railway construction and is the most basic work in the entire railway construction project. It not only directly affects the rationality of the entire design scheme, but also directly relates to the budget of the entire railway project. Therefore, it is particularly important to obtain complete, accurate and reliable core data from the borehole as much as possible. [0003] In the investigation of railway engineering, we often encounter accumulation strata formed by geological phenomena such as weathering and transportation, such as weathering, river bed, glacier ice water, landslide, engineering backfill and other accumulation strata. Accumulation of filling ma...

Problems solved by technology

[0005] However, when percussion drilling breaks rocks and formations, a large number of broken particles and dust appear, and a large amount of water is sprayed from the top of the casing in formations rich in groundwater, which has a negative impact on the construction environment and the health of operators.
