Deposited dust flushing structure for coal mine gas drainage pipeline

Abstract

The utility model relates to the technical field of coal mining and production, in particular to an accumulated dust flushing structure for a coal mine gas drainage pipeline, and aims to solve the problems that in the existing accumulated dust cleaning process of the coal mine gas drainage pipeline, the pipeline distribution range is wide, the route is long, and the pipeline hanging height is high. The problems of long accumulated dust washing time, poor washing effect, high potential safety hazard and limited production efficiency of coal mining are solved. According to the structure, the flushing pipe with the water spraying holes is connected to the top of the coal mine gas drainage pipeline, and the control valve is additionally arranged between the flushing pipe and the high-pressure hose, so that the phenomenon that an operator does not directly use the high-pressure water spraying hose to flush accumulated dust of the drainage pipeline is effectively avoided, and remote opening of the control valve is realized; and the accumulated dust of the gas drainage pipeline is quickly and efficiently washed and cleaned, so that the overall operation safety and efficiency of a coal mining site are improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal mining production, specifically relates to a coal mine gas drainage pipeline dust flushing structure. BACKGROUND

[0002] Adopting pre-extraction coal seam gas is a main outburst prevention measure to ensure the safety production of outburst mine, but the dust produced in daily production is accumulated on the gas drainage pipeline, and flushing the dust accumulated on the gas drainage pipeline is also an important work of dust control, because of the wide distribution range, long route and high hanging height of the pipeline, the personnel generally spend a long time in flushing the dust, the flushing effect is poor, and there are production safety hazards, therefore, it is necessary to further optimize the structure of the gas drainage pipeline dust flushing to ensure the safety, effectiveness and rapid cleaning of the gas drainage pipeline dust, and achieve the purpose of safe production and accident prevention. SUMMARY

[0003] The utility model provides a coal mine gas drainage pipeline dust flushing structure to solve the problems in the above background.

[0004] In order to realize the above purpose, the utility model adopts the following technical scheme:

[0005] A coal mine gas drainage pipeline dust flushing structure, comprising a flushing pipe arranged at the top of the gas drainage pipe, the flushing pipe being connected with a high-pressure hose, the high-pressure hose being provided with a control gate valve, and the high-pressure hose being further connected with a dustproof pipe.

[0006] Further, a plurality of water spraying holes are uniformly arranged at the bottom side wall of the flushing pipe, and the water spraying holes are correspondingly arranged at the top of the gas drainage pipe.

[0007] Further, the flushing pipe and the high-pressure hose are connected through a connector.

[0008] The utility model has the following beneficial effects:

[0009] The coal mine gas drainage pipeline dust flushing structure provided by the utility model connects the flushing pipe with water spraying holes at the top of the coal mine gas drainage pipeline, and installs a control valve between the flushing pipe and the high-pressure hose, which effectively avoids the phenomenon that the operator directly uses the high-pressure water spraying hose to flush the dust accumulated on the drainage pipeline, realizes the opening of the control valve at a distance, and performs rapid and efficient flushing and cleaning of the dust accumulated on the gas drainage pipeline, thereby improving the overall operation safety and efficiency of the coal mining site, and solving the problem that the dust accumulated on the gas drainage pipeline is difficult to clean due to the wide distribution range, long route and high hanging height of the pipeline, which results in a long time consumption, poor flushing effect and high safety hazards, and finally limits the production efficiency of the coal mining.
