Description
Technical field
This utility model relates to a kind of coal mine gas extraction pipeline deslagging jettison gear, particularly relates to a kind of coal mine gas extraction pipeline simple tubulose deslagging jettison gear.
Background technology
In recent years, along with country's increasing to control of coalmine gas dynamics, the input of gas pumping is also continued to increase by each coal mining enterprise.Down-hole drilling mash gas extraction, as administering gas means the most direct, maximally effective, has extremely important status, but there are problems in extraction pipeline gas monitor.
When measuring gas pumping parameter at the scene, the most measurement equipment of domestic employing is gas pumping parametric synthesis analyzer (that is: Chinese Patent Application No. is the invention " gas drainage under suction parametric measurement device " of 201320627088.0), the mozzle (that is: Chinese Patent Application No. is the invention " a kind of for gas drainage under suction mozzle " of 200720089241.3) that corresponding sample collection device is attached on extraction pipeline.In this mozzle, a dust-separation filter screen is had before gas surveying hole, its Main Function completely cuts off coal dust exactly, prevent from entering gas surveying hole, but in actual use, bulky grain coal dust is easily blocked in herein, coal dust, aqueous mixtures are deposited in herein in the course of time, it not only affects extracting result, also makes troubles for accurate location parameter and the preparatory of parametric measurement device.In addition mozzle is completely embedded with drainage tube when installing, and processes blocking the most extremely difficult, and field worker is for processing conveniently, or the mozzle that firmly collides with, or by shaft-like hard thing admittance flow tube, this most more or less causes injury to mozzle.
For preventing cinder, coal dust and water slug many scholars in extraction pipeline from have also been invented the slagging-off of some practicalities, dedusting and jettison gear, such as: Chinese Patent Application No. be 201120203434.3 invention " mine gas extraction pipeline gas control automatic slag-discharging water draining device ", Chinese Patent Application No. be 201220716340.0 invention " a kind of gas in mine extraction pipeline Auto-drainage deslagging device ", Chinese Patent Application No. be 201220448131.2 invention " slag-draining device ".These devices on the one hand volume ratio is relatively big, uses inconvenience；On the other hand these devices are typically inconvenient to be used in one borehole extraction branch road, can arrange thousands of pre-draining boreholes as taken out in advance at one in a gate road of work surface, we are it cannot guarantee that each boring configures the most bulky slagging-off, dedusting and jettison gear.And, after current most mining slagging-off, dedusting and jettison gear are typically placed in mozzle, its objective is to prevent cinder, coal dust and water from entering in the main line of region extraction pipeline, less consideration cinder, coal dust and water can be blocked in the extraction branch road of mozzle front end.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art, it is provided that a kind of simple in construction, and volume is little, it is simple to remove the gred in extraction branch road before being connected to mozzle, dedusting and jettison gear, it is achieved the technical solution of the utility model is as follows:
A kind of coal mine gas extraction pipeline simple tubulose deslagging jettison gear, including T-shaped pipe, described T-shaped pipe includes DC tube and collecting pipe；Described DC tube includes air inlet and gas outlet, and air inlet connects hole sealing tube, and gas outlet connects mozzle；The inwall of DC tube is provided with dust-separation filter screen, dust-separation filter screen is perpendicular to the axis of DC tube and the plane at the axis place of collecting pipe, direct current tube wall laminating above the upper end of dust-separation filter screen and collecting pipe, the DC tube of the bottom of dust-separation filter screen and one end, gas outlet is fitted with collecting pipe intersection, and dust-separation filter screen is β with the angle of DC tube axis；The lower end of described collecting pipe is sealedly connected with rubber sleave by snap close.
Described 45 °≤β≤75 °.
The beneficial effects of the utility model are: this utility model simple in construction, volume are little, before being easy to be connected to mozzle, extraction branch road removes the gred, dedusting and jettison gear, the effective extraction branch road that solves blocks, it is ensured that mozzle collects the degree of purity of gas, and the accuracy of location parameter.

Detailed description of the invention
A kind of coal mine gas extraction pipeline simple tubulose deslagging jettison gear as described in Fig. 1-4, including T-shaped pipe, described T-shaped pipe includes DC tube and collecting pipe；Described DC tube includes air inlet and gas outlet, and air inlet connects hole sealing tube, and gas outlet connects mozzle；The inwall of DC tube is provided with dust-separation filter screen, dust-separation filter screen is perpendicular to the axis of DC tube and the plane at the axis place of collecting pipe, direct current tube wall laminating above the upper end of dust-separation filter screen and collecting pipe, the DC tube of the bottom of dust-separation filter screen and one end, gas outlet is fitted with collecting pipe intersection, and dust-separation filter screen is 60 ° with the angle of DC tube axis；The lower end of described collecting pipe is sealedly connected with rubber sleave by snap close.
Being mixed with gas being entered by sealing of hole pipe end in apparatus of the present invention of cinder, coal dust and water, cinder, coal dust are stopped by dust-separation filter screen, enter arm under gravity；Water patch DC tube tube wall flowing, under action of gravity, flows into collecting pipe at collecting pipe with DC tube junction；The gas flow guiding pipe end removing cinder, coal dust and water flows out.
This utility model device is added in extraction pipeline branch road, during the later stage stablizes extraction, can effectively collect cinder, coal dust and the water extracted out by boring, it is ensured that at the degree of purity of the mozzle collection gas that water conservancy diversion pipe end is installed, and the accuracy of location parameter.
