Gas-slag separation device for drilling

Abstract

The invention discloses a gas-slag separation device for drilling. The gas-slag separation device for drilling comprises two wall plates, a left side plate, a separation plate and a right side plate,wherein the two wall plates are symmetrical at the front side and the back side; the wall plates are of L-shaped structures and are fixedly connected through the left side plate and the right side plate; the separation plate is fixedly connected to the upper part of the middle of the wall plate; a horizontal cover plate is fixedly connected to the top ends of the wall plates, the left side plate and the separation plate; a gas-slag inlet pipe and a blowout control connecting pipe are arranged on the cover plate; a lower inclined plate of an arc-shaped structure is fixedly connected among the bottom of the left side plate, the bottom end of the right side plate and the wall plate; the right side plate is in inclined arrangement; a slag extraction device is arranged on the right side plate;and a slide plate is fixedly connected between the wall plates. Through the arrangement of the separation plate and the slide plate, gas and slag are separated in the flowing process; the slags are discharged through the slag extraction device; the gas enters an extraction pipe to be exhausted; an extraction pipe blockage phenomenon cannot occur; and a good effect is achieved.

Description

technical field [0001] The invention relates to an air slag separator, in particular to an air slag separation device for drilling, and belongs to the technical field of coal mine drilling anti-blowout and dust reduction equipment. Background technique [0002] Usually, during the drilling process, there are serious safety hazards due to the large gas content of spray holes; at the same time, the dust generated during drilling is very large, which seriously affects the health of employees; the drilling slag cannot be effectively discharged, which seriously affects Civilized production and quality standardization in underground tunnels. During the drilling process, negative pressure is generally used to extract gas and drilling slag in order to prevent injection holes, and dust reduction treatment is carried out at the same time; however, if gas and slag separation and dust reduction treatment are not carried out, it is easy to cause blockage of the extraction pipe and gas le...

[0002] Usually, during the drilling process, there are serious safety hazards due to the large gas content of spray holes; at the same time, the dust generated during drilling is very large, which seriously affects the health of employees; the drilling slag cannot be effectively discharged, which seriously affects Civilized production and quality standardization of underground tunnels

During the drilling process, negative pressure is generally used to extract gas and drilling slag in order to prevent injection holes, and dust reduction treatment is carried out at the same time; however, if gas and slag separation and dust reduction treatment are not carried out, it is easy to cause blockage of the extraction pipe and gas leakage. Drainage utilization; how to effectively prevent the occurrence of the above phenomenon, this is a technical problem that needs to be solved
