Description
Technical field
The utility model relates to the mine gas monitoring of a kind of colliery and takes out in advance and sampling apparatus.
Background technology
In recent years, how to strengthen the mine disaster preventing and controlling, how correctly to handle the relation of safety and production, safety and benefit, fulfil the coal mine safety monitoring function how accurately, in real time, fast, guarantee the efficient running of rescue and relief work, safety rescue, become the most important thing of coal mine working.Facts have proved that quickly and accurately mine gas being tested and the data that test draws are made analysis and judgement is very important to reducing mine fire and gas explosion.The coal mine gas check and analysis are the essential bases that ensure mine safety, are the fundamental basis of colliery disaster prevention, improvement and disaster relief decision-making.Mine fire beam tube monitoring system is that coal mine gas detects the most frequently used method.
Lay the place difference according to equipment, mine fire beam tube monitoring system is divided into ground type and down-hole type.The ground type to ground, adopts the Ground analysis instrumental analysis by " beam tube " suction downhole gas sample, carries out continuous monitoring; But because its exhaust pipe is long, it is relatively poor that the gas sample is analyzed real-time, and be easy to the accuracy of factor affecting gas analyses such as because of the pipeline windage excessive or pipeline principal fault, thereby influence monitoring accuracy.The down-hole type carries out field monitoring sampling, analyzing and processing by being placed on the monitoring equipment of down-hole to the parameter of required monitoring.Thereby avoid the monitoring analysis error brought because of exhaust pipe is long as far as possible, improved accuracy, realized that mine fire monitors in real time, and a large amount of saving cost such as material and installation, maintenance.
Efficiently, stable gas sampling system and high-performance, accurate gas analysis system are the colliery mine gas prerequisites of monitoring in real time.Therefore, need the mine gas monitoring of a kind of like this colliery to take out in advance and sampling apparatus:, to realize the effect that need record gaseous sample under the production wells as the parts of colliery mine gas monitoring device.Small and exquisite, exquisite, the compact conformation of the utility model design is operated simple and easyly, easy to maintenance, sturdy and durable, is convenient to install and use, and the collecting efficiency height, the sampling time lacks, and places in the case, is applicable under the coal mine.
The utility model content
The purpose of this utility model provides the mine gas monitoring of a kind of colliery and takes out in advance and sampling apparatus, adopts incorporate structural design, and gas sampling, flow demonstration and gas circuit control are integrated, and volume is little, installation, easy to use; The reasonably gas circuit design of independently bleeding, pipeline is lacked, and reach air resistance and minimize, the collecting efficiency height, the sampling time lacks; For every road beam tube configuration flow quantity sensor, measure its flow, have or not obstruction by flow monitoring reflection down-hole beam tube, reflect the sampling situation of every road beam tube; Procedure auto-control is controlled the unlatching of sampling pump automatically and is closed, and the beam tube pipeline of each monitoring can be by independent the enabling or stopping using of program, and program is adjusted each beam tube separately checkout time, need not any manual intervention, the automaticity height; The anti-suck function solves effectively and shuts down backwater and sample gas contamination phenomenon; Sampling system places in the cabinet, and insulation, good reliability are applicable under the coal mine.
The purpose of this utility model is to be achieved through the following technical solutions:
The mine gas monitoring of a kind of colliery is taken out and sampling apparatus in advance, comprise body, the left side of described body is provided with bus-bar, and bus-bar connects solenoid valve by pipeline, solenoid valve is connected with sampling pump by pipeline, and the pipeline that wherein connects solenoid valve and sampling pump is provided with flow sensor.
The beneficial effects of the utility model are: be responsible for gas sampling work, so that mine gas monitoring device spot sampling and carry out infrared analysis under coal mine, realized that the colliery mine gas monitors in real time, also realized that the coal-mine fire beam tube monitors robotization control in real time simultaneously, select high-quality parts for use, installation, easy to use, pumping efficiency height, reliability height, life-span is long, and is non-maintaining.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is that mine gas monitoring in the described colliery of the utility model embodiment is taken out and the structural representation of sampling apparatus in advance.
Among the figure:
1, body; 2, bus-bar; 3, solenoid valve; 4, sampling pump; 5, flow sensor.
Embodiment
As shown in Figure 1, the mine gas monitoring of the described a kind of colliery of the utility model embodiment is taken out and sampling apparatus in advance, comprise body 1, the left side of described body 1 is provided with bus-bar 2, bus-bar 2 connects solenoid valve 3 by pipeline, solenoid valve 3 is connected with sampling pump 4 by pipeline, and the pipeline that wherein connects solenoid valve 3 and sampling pump 4 is provided with flow sensor 5.
Sampling pump 4 will will be monitored gas by in the gentle road of beam tube explosion isolation device suction the utility model.Tested gas is temporary in bus-bar 2.Article 8, pipeline is realized the pipeline selection function by bus-bar 2 and solenoid valve 3, selects the gas of a certain pipeline to enter infrared gas analyzer analysis.Flow sensor 5 is serially connected in the utility model, detects the flow of tested pipeline gas, monitors duty of the present utility model.Sampling pump 5 is that a kind of minipump can vacuumize closed container for a long time, can drive bigger load.The end that can be applicable to bleed have valve, need uninterrupted running in continuous 24 hours under with big load condition occasion, utilize negative pressure, gas sample is pumped in the device, finish the mine gas sampling work.The utility model is placed in the cabinet, is applicable under the coal mine, and each air-path interface connects closely, and each arrangements of components rationally, firmly is enough to guarantee the long-term daily use of whole device.
The utility model course of work is: sampling pump 4 moves automatically by programmed control, utilize negative pressure, the tested gas sample of 8 the beam tube pipelines in down-hole is pumped in the bus-bar 2, selecting wherein by bus-bar 2 and solenoid valve 3 again, the gas sample of a pipeline enters in the infrared spectrum analyser, by flow sensor 5 monitoring sampling work states, finished the work of mine gas sampling simultaneously.The utility model is the colliery mine gas basis of monitoring in real time, and the gas sample of efficient, reliable, safe collection of coal mine down-hole to analyze, is realized the real-time monitoring of mine mine gas, for Safety of Coal Mine Production, the disaster relief etc. is offered high-quality service.
