Abstract
The utility model relates to a colliery is the auxiliary assembly of gas drainage pipeline in the pit, specifically is a gas drainage pipeline hinders and explodes sand package, including last zoarium (1) and lower fit (2), it constitutes the cylinder through bolted connection to go up after be in the same place fit (1) and down fit (2), cylinder central authorities reserve out the round cylindrical space of installation gas drainage pipeline, go up and to set up the survivor of a murder attempt on fit (1), fill full fine sand in to the cylinder through the survivor of a murder attempt. The cylinder supports through a plurality of concrete column bases. When the gas drainage pipeline is inside when taking place the burning and leading to the pipeline to burst, should hinder and explode the sand package and can effectually play the effect of exploding that hinders, prevent accident expansion, simultaneously, the the device installation is simple, and is compatible strong, has fine popularization prospect.
Description
Technical field
The utility model relates to the auxiliary equipment of coal mine gas extraction pipeline, is specially a kind of methane gas extraction pipeline explosion arrestment sand bag.
Background technology
According to group company's associated documents requirement, in low concentration gas extraction pipeline, methane gas extraction pipeline explosion arrestment sand bag should be installed, guarantee gas drainage system safe operation further.But up to the present, also do not have ripe product, can not introduce also cannot reference.
In order to solve this difficult problem, the person skilled joint research of extraction specialty, designed, designed, machined methane gas extraction pipeline explosion arrestment sand bag.
Summary of the invention
The utility model, in order to solve the explosion arrestment problem of underground coal mine low concentration gas extraction pipeline, provides a kind of methane gas extraction pipeline explosion arrestment sand bag.
The utility model adopts following technical scheme to realize:
A kind of methane gas extraction pipeline explosion arrestment sand bag, comprises zoarium and lower zoarium, forms cylinder after together with described upper zoarium is bolted with lower zoarium, and described cylinder central authorities reserve the cylindrical space installing methane gas extraction pipeline; Described upper zoarium arranges the survivor of a murder attempt, in cylinder, is filled with fine sand by the survivor of a murder attempt.
Described cylinder is supported by some concrete column bases, to the bearing down of methane gas extraction pipeline, guarantees methane gas extraction pipeline system stability for offsetting fine sand in sand bag.
When explosion occurs extraction pipeline, fire-fighting sand enters in extraction pipeline by explosion vent, stamps out the flames, and plays the effect of pipeline explosion arrestment.
This explosion arrestment sand bag advantage specific as follows:
1, safety: the connection of all component is all by strict manual welding, and safety factor is high.
2, stability: the quick-fried sand bag of drainage tube roadlock effectively can play explosion-resistant effect, Accident prevention expands.
3, economy: structure is simple, cheap, easy to process, and production and processing aspect also can autonomy-oriented; Compatible strong, can adjust flexibly according to different extraction pipelines.
Economic benefit is as follows:
The quick-fried sand bag of drainage tube roadlock is installed simple, and security performance is high.And production and processing aspect also can autonomy-oriented, greatly reduces cost of production, save the spending of extraction correlative charges.
Social benefit is as follows:
Be applicable to any mine gas extraction system, can adjust flexibly according to different extraction pipelines, be easy to promote comprehensively; This sand bag effectively can play explosion-resistant effect, facilitates Safety of Coal Mine Production.
When the generation burning of methane gas extraction pipeline inside causes pipelines from bursting, this explosion arrestment sand bag effectively can play explosion-resistant effect, and Accident prevention expands; Meanwhile, this device is installed simple, compatible strong, has good promotion prospect.
Accompanying drawing explanation
Fig. 1 represents the schematic diagram of upper and lower zoarium.
In figure, 1-is upper fit, fit under 2-.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is described in detail.
A kind of methane gas extraction pipeline explosion arrestment sand bag, as shown in Figure 1, comprises fit 1 and lower fit 2, described fit 1 together with lower fit 2 are bolted after form cylinder, described cylinder central authorities reserve the cylindrical space installing methane gas extraction pipeline; On described fit 1, the survivor of a murder attempt is set, in cylinder, is filled with fine sand by the survivor of a murder attempt.
Be produced as follows:
The specification of cylinder is 150cm × 80cm × 70cm.Upper zoarium and lower zoarium all adopt 30mm angle bar to be welded into skeleton, 3mm steel plate is adopted to carry out all round closure, bolt is fixedly connected with rear formation rectangle cylinder, at the circular space of the reserved Ф 377mm of its both sides central authorities, for being wrapped up wherein by the methane gas extraction pipeline of internal diameter Ф 355mm.Be filled with a sealing with raw stock in cylinder and between methane gas extraction pipeline, the survivor of a murder attempt reserved by upper zoarium fills fine sand in sand bag, can play the effect of protection methane gas extraction pipeline.
Described cylinder is supported by some concrete column bases, can offset fine sand in sand bag completely and, to the bearing down of methane gas extraction pipeline, guarantee methane gas extraction pipeline system stability.
Every two explosion arrestment sand bags are one group, and overall length is 3m, and the fine sand capacity in one group of explosion arrestment sand bag is: 1.34m
3.
Methane gas extraction pipeline explosion arrestment sand bag operating principle is, when explosion occurs extraction pipeline, fire-fighting sand enters in extraction pipeline by explosion vent, stamps out the flames, and plays the effect of pipeline explosion arrestment.
Finally it should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted; although be described in detail with reference to the utility model embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement; do not depart from the spirit and scope of the technical solution of the utility model, it all should be contained in claims of the present utility model.
Claims (2)
