Abstract
To hole three anti-seal gas drawing station devices, comprise interconnective sealing of hole sleeve and sealer connector, described sealer connector rear end connects arc-shaped connector and drilling machine clamp holder successively, and the connector coal dust outlet of sealer connector exports with the connector coal dust of arc-shaped connector and is connected by three-limb tube.By stifled for the sealing of hole of boring tight, the gas taken out in advance in coal seam in advance, collects all methane gas.
Description
Technical field
The utility model relates to safety-security area under ore deposit, three anti-seal gas drawing station devices of specifically holing.
Background technology
At present, solving the gas problem of mine main has two kinds of means, and one be row, two is take out.So-called gas drainage under suction is exactly the negative pressure utilizing plant equipment and pipe special to cause, and is released by the gas existed or discharge, be transported to the way of ground or other safety places in coal seam.In order to reduce or eliminate the restriction of gas to shaft production, the gas by taking out coal seam in advance is in advance only had to solve the gas emission of mining and in tunneling process, but when taking out coal-bed gas in advance in advance by boring, there is the effect that a serious problem governs gas drainage under suction, it is not tight that is exactly the sealing of hole of holing, when holing, if there is Gas Outburst, hole packer very likely can spray with gas, damages field personnel.
Utility model content
In order to solve the problem, the utility model provides boring three anti-seal gas drawing station device, and by stifled for the sealing of hole of boring tight, the gas taken out in advance in coal seam in advance, collects all methane gas.
For reaching above-mentioned utility model object, the technical solution adopted in the utility model is: boring three anti-seal gas drawing station devices, comprise interconnective sealing of hole sleeve and sealer connector, described sealer connector rear end connects arc-shaped connector and drilling machine clamp holder successively, and the connector coal dust outlet of sealer connector exports with the connector coal dust of arc-shaped connector and is connected by three-limb tube.
The utility model beneficial effect is: more reasonable to the sealing of boring, is collected, prevent gas from spraying by clamper to all methane gas.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Be labeled as in figure: 1, sealing of hole sleeve, 2, sealer connector, 201, the outlet of connector coal dust, 3, drilling machine clamp holder, 4, three-limb tube, 5, arc-shaped connector, 501, the outlet of connector coal dust, 6, air inlet port.
Detailed description of the invention
As shown in the figure, three anti-seal gas drawing station devices of holing are made up of sealing of hole sleeve 1, sealer connector 2, drilling machine clamp holder 3, arc-shaped connector 5 and three-limb tube 4.
1. after coal bed drilling, by sealing of hole sleeve 1 patchhole, be connected by down-hole source of the gas, open valve with air inlet port 6, sealing of hole sleeve rubber topping expands, by borehole sealing.
2. arc-shaped connector is connected with drilling machine clamp holder, finally sealer connector is connected with arc-shaped connector.
When starting to hole, a large amount of coal cinders and coal dust enter sealer connector through hole packer sleeve, coal cinder and larger coal dust are exported by connector coal dust under gravity discharges, a small amount of coal dust enters arc-shaped connector through sealer connector, to be connected with drilling machine clamp holder due to arc-shaped connector and to seal, coal dust is at arc clamper Inner eycle and fall, discharge through the outlet of connector coal dust, the outlet of connector coal dust exports with connector coal dust and is connected by three-limb tube, and coal dust and coal cinder directly enter three anti-devices through three-limb tube to carry out processing and discharging.
Claims (1)
1. boring three anti-seal gas drawing station devices, comprise interconnective sealing of hole sleeve (1) and sealer connector (2), it is characterized in that: described sealer connector (2) rear end connects arc-shaped connector (5) and drilling machine clamp holder (3) successively, connector coal dust outlet (201) of sealer connector (2) exports (501) with the connector coal dust of arc-shaped connector (5) and is connected by three-limb tube (4).
