Description
Technical field
The utility model relates to a kind of negative pressure extraction gas device, especially a kind of negative pressure extraction gas draining slag device.
Background technology
In coal mining, draw out methane, coal bed gas time, dust grain slag easily enters in extraction pipeline, and grain slag produces drag effects and to draw out methane gas effectiveness, and grain slag discharge easily blocks extraction pipeline not in time.The negative pressure automatic slag-discharging water draining apparatus structure sold in the market is complicated, and exhaust outlet position great majority are arranged on horizontal direction, and time grain slag must reach a certain amount of, could realize automatic slag-discharging water draining function.But in accumulation grain slag process, part grain slag enters extraction pipeline again, affects negative pressure of suction resistance, even blocks extraction pipeline, causes very large risk.
Utility model content
For overcoming above the deficiencies in the prior art, it is simple that the technical problems to be solved in the utility model is to provide a kind of structure, and manufacturing process is ingenious, easy to maintenance, discharge grain slag is timely, sensitive, reliable, can prevent from discharging the negative pressure extraction gas draining slag device that grain slag space-time gas enters ponding slag case.
The technical solution of the utility model is: a kind of negative pressure extraction gas draining slag device, comprises extraction pipeline and ponding slag case, and described ponding slag case is connected with extraction pipeline by connecting extraction pipeline short section, and the bottom of described ponding slag case is provided with draining slag chute; Described draining slag chute lower end is provided with grain slag and collects cuff, and the two ends that described grain slag collects cuff communicate; Described grain slag is collected cuff one end and is fixed on draining slag chute lower end by tight loop, and it is unsettled that described grain slag collects the cuff other end; Described draining slag chute lower end is provided with whippletree, and described whippletree is provided with spring, and described spring upper end is provided with hollow spherical value.
Further, the shape of described draining slag chute is infundibulate.
Further, the material that described grain slag collects cuff is canvas.
Further again, the material of described hollow spherical value is rubber.
The beneficial effects of the utility model are: the shape of described draining slag chute is infundibulate, and grain slag can flow to bottom draining slag chute smoothly; The material that described grain slag collects cuff is canvas, has good flexibility, has good air tight property simultaneously.When extraction pipeline does not have grain slag, form negative pressure in water tank, hollow spherical value rises certain altitude under spring draft force traction, and grain slag is collected cuff and shunk airtight by suction function automatic pick in water tank, ensures in ponding slag case airtight, does not enter air.When there being grain slag, hollow spherical value is subject to suction function and the certain altitude that rises under spring draft force traction, and it is flexible because of it that grain slag collects cuff, and glassware for drinking water has permeability, and the Action of Gravity Field of water is opened and collected cuff down draining slag.The flexible acting in conjunction of cuff is collected owing to being subject to negative pressure and grain slag in ponding slag case, the size of the draining quantity of slag and grain slag are collected cuff and are opened the in the same size of mouth, the material that grain slag collects cuff is canvas, there is good air tight property and flexibility, guarantee that while draining slag, stopped air enters extraction pipeline, solves leakage problem.When extraction pipeline does not have negative pressure, hollow spherical value compresses draining slag chute by gravity and spring draft force effect, avoids this gas leak of extraction pipeline Neva.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is the main TV structure schematic diagram of the utility model;
Fig. 2 is the utility model sectional structure schematic diagram.
In figure: extraction pipeline 1, connect extraction pipeline short section 2, ponding slag case 3, tight loop 4, grain slag collects cuff 5, draining slag chute 6, spring 7, hollow spherical value 8, whippletree 9.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of negative pressure extraction gas draining slag device, comprises extraction pipeline 1 and ponding slag case 3, and described ponding slag case 3 is connected with extraction pipeline 1 by connecting extraction pipeline short section 2, and the bottom of described ponding slag case 3 is provided with draining slag chute 6; Described draining slag chute 6 lower end is provided with grain slag and collects cuff 5, and the two ends that described grain slag collects cuff 5 communicate; Described grain slag is collected cuff 5 one end and is fixed on draining slag chute 6 lower end by tight loop 4, and it is unsettled that described grain slag collects cuff 5 other end; Described draining slag chute 6 lower end is provided with whippletree 9, and described whippletree 9 is provided with spring 7, and described spring 7 upper end is provided with hollow spherical value 8.
Further, the shape of described draining slag chute 6 is infundibulate.
Further, the material that described grain slag collects cuff 5 is canvas.
Further again, the material of described hollow spherical value 8 is rubber.
As depicted in figs. 1 and 2, when ponding slag case 3 does not have grain slag, in ponding slag case 3, form negative pressure, hollow spherical value 8 is by spring 7 tractive force effect rising certain altitude, grain slag is collected cuff 5 and is shunk airtight by suction function automatic pick in water tank, ensures in ponding slag case 3 airtight, does not enter air.
When ponding slag case 3 has grain slag, by suction function hollow spherical value 8 by the certain altitude that rises under the effect of spring 7 tractive force, it is flexible because of it that grain slag collects cuff 5, the Action of Gravity Field of water is collected cuff 5 and is automatically opened, grain slag starts to discharge, grain slag collects suction function in cuff 5 flexibility itself and ponding slag case 3 simultaneously, ensure that air does not enter in water tank when there being a small amount of grain slag to discharge.
Collect the flexible acting in conjunction of cuff 5 itself owing to being subject to negative pressure and grain slag in ponding slag case 3, grain slag collects cuff 5 when by vacuum force, and grain slag collects cuff 5 in air-tight state, prevents air from entering.The size of the draining quantity of slag and grain slag are collected cuff 5 and are opened the in the same size of mouth, guarantee while draining slag, have stopped air and entered extraction pipeline 1, solved the problem of gas leakage.
When not having negative pressure in extraction pipeline 1, globe valve 8 compresses rhone at spring 7 tractive force and Action of Gravity Field own, prevents methane gas to leak.
The shape of draining slag chute 6 is infundibulate, ensure that a small amount of ponding slag can be discharged in time.
The utility model structure is simple, and manufacturing process is ingenious, easy to maintenance, and discharge grain slag is timely, sensitive, reliable, solves the technical barrier that discharge grain slag space-time gas enters ponding slag case, has good prospect and market value.
By reference to the accompanying drawings the preferred detailed description of the invention of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken that those skilled in the art possess, various change can also be made without departing from the concept of the premise utility.
