Abstract

The utility model discloses a pneumatic drainage device, comprising a water accumulation barrel and a water back preventing inlet valve connected with the water accumulation barrel, a back stop discharging valve, wherein the water back preventing inlet valve communicates with the suction and discharge pipes. The back stop discharging valve communicates with the drainage pipes. The water accumulation barrel is provided with a float and is hung at the lower end of the core of a compressed air control valve through a guide bar. The compressed air control valve communicates with a down-hole inputsystem through a pressure inlet air duct. The utility model has reasonable design, good automatic discharging effect, simple structure, low cost and convenient installation, and can be widely appliedto the automatic drainage of main pipe, collecting main and branch pipe in the coal mine down-hole permanent gas drainage pipe system and the down-hole temporary drainage pipe system.

Description

Pneumatic tailrace
Technical field
The utility model relates to a kind of discharge water device that is used for the interim extraction pipe-line system of coal mine gas extraction pipe-line system and down-hole, particularly a kind of automatic jettison gear.
Background technology
The discharge of wastewater of coal mine gas extraction pipe-line system and the interim extraction pipe-line system in down-hole mainly contains and manually discharges water and the dual mode that discharges water automatically at present, manually discharge water because pipeline is long, it is a little many to discharge water, and needs to be equipped with great amount of manpower, emission effect difference and cost height; And the existing system and device complexity that discharges water automatically is with high costs, and the erection procedure complexity, to interim extraction pipeline and inapplicable.
The utility model content
The purpose of this utility model provide a kind of automatic emission effect good and stable and reliable for performance pneumatic tailrace, and the utility model is simple in structure, with low cost, easy for installation.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of pneumatic tailrace, comprise ponding bucket and anti-water intaking valve, the check discharging valve against the current that link to each other with the ponding bucket, anti-water intaking valve is against the current connected extraction pipeline, the check discharging valve is connected discharge pipe line, be provided with a float in the ponding bucket, and hang one by guide rod and to press wind control valve spool lower end, described pressure wind control valve is by ventilation system under the entrance pressure airduct connected well.
Further described ponding bucket also is communicated with a safety valve.When the pressure in the ponding bucket was excessive, safety valve was opened automatically, played the effect of pressure release, prevented the excessive phenomenon of blasting of ponding bucket internal cause pressure.
The beneficial effects of the utility model are, reasonable in design, automatically precise control is reliable, can be easily and colliery draw out methane pipeline or other negative-pressure gas pipeline connection, ponding in the pipeline is discharged smoothly, simultaneously simple in structure, with low cost and install and keep easyly, can be applicable to permanent gas pumping pipe-line system under the coal mine, also be applicable to the discharging water automatically of the person in charge, main and arm of the interim extraction pipe-line system in down-hole.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the theory structure schematic diagram of pneumatic tailrace described in the utility model.
Among the figure:
1, ponding bucket; 2, extraction pipeline; 3, entrance pressure airduct; 4, anti-reverse water intaking valve; 5, float; 6, safety valve; 7, press the wind control valve; 8, check discharging valve.
The specific embodiment
As shown in Figure 1, the described pneumatic tailrace of the utility model embodiment, comprise ponding bucket 1, anti-water intaking valve 4 against the current, check discharging valve 8 and press wind control valve 7, anti-water intaking valve against the current 4 is connected extraction pipeline 2 and ponding bucket 1,8 of check discharging valves are connected ponding bucket 1 and discharge pipe line, be provided with the float 5 of a band guide rod in the ponding bucket in addition, it is hung in the spool lower end of pressing wind control valve 7 by guide rod, and described pressure wind control valve 7 is by ventilation system under entrance pressure airduct 3 connected wells.
The embodiment of optimizing is that ponding bucket 1 also is connected with a safety valve 6, and it is set at when the pressure in the ponding bucket and opens automatically during greatly to certain value, plays the effect of pressure release, prevents the excessive phenomenon of blasting of ponding bucket internal cause pressure.
Operating principle of the present utility model is: the waste water in the extraction pipeline 2 enters ponding bucket 1 by anti-water intaking valve 4 against the current under the methane gas pressure in pipeline, constantly rise in the inner bucket water position, float 5 promotes guide rods and rises, and when float 5 rises to a certain degree, guide rod promotes to press wind control valve 7 to open, the down-hole ventilation system is communicated with ponding 1, because down-hole ventilation system air pressure is big, then impel anti-water intaking valve 4 against the current to close, check discharging valve 8 is opened, realization discharges water, and original pump drainage water system is discharged through the down-hole again; After liquid level was reduced to certain altitude, float 5 drove guide rod and descends, and presses wind control valve 7 to close, and water level continues decline back ponding bucket internal pressure and reduces, and anti-water intaking valve 4 is against the current opened, and check discharging valve 8 cuts out, and finishes a draining circulation.
Because the utility model is reasonable in design and simple in structure being easy to installed, overall process does not need Artificial Control, and can be easily and the colliery pipeline connection that draws out methane, ponding in the pipeline is discharged smoothly, be widely used in the discharging water automatically of the person in charge, main, arm of the interim extraction pipe-line system of permanent gas pumping pipe-line system and down-hole under the coal mine, reliable and stable drainage performance ensures the unblocked of pipe-line system effectively, fully improves extraction efficient, to guarantee safety in production.

Claims (2)

1, a kind of pneumatic tailrace, it is characterized in that, comprise ponding bucket and anti-water intaking valve, the check discharging valve against the current that link to each other with the ponding bucket, anti-water intaking valve is against the current connected extraction pipeline, the check discharging valve is connected discharge pipe line, be provided with a float in the ponding bucket, and hang in a pressure wind control valve spool lower end by guide rod, described pressure wind control valve is by ventilation system under the entrance pressure airduct connected well.
2, pneumatic tailrace according to claim 1 is characterized in that, the ponding bucket also is communicated with a safety valve.
