Abstract
A kind of coal mine gas extraction pipeline tailrace, comprises water inlet, slag-drip opening and Auto-drainage pipe, and wherein water inlet is controlled by plug of intaking, and when in water tank, water level raises, ball float raises gradually because of buoyancy, until pressure is filled in water inlet by floating arm, blocks water inlet.Meanwhile, floating arm is upwards opened inlet valve by push rod, and outside air enters rapidly, and the water pressure pushing one way valve plug in casing is opened outfall and discharged water.Ball float declines because of the water surface, and drive floating arm will to intake Sai Lakai, continue water inlet, the pipeline of inlet valve decline air-isolation guarantee extraction simultaneously seal, outfall also can be closed because spring promotes one way valve plug.In the process that discharges water, drilling cuttings is assembled under the filter screen tilted stops, regularly by manually opening valve deslagging.Methane gas extraction pipeline draining deslagging is carried out in circulation like this.Its structure is simple, easy to use, Be very effective, and energy is automatic draining in time, prevents extraneous gas from entering extraction pipeline simultaneously, improves gas pumping efficiency.
Description
Technical field
The utility model relates to a kind of device of coal mine gas extraction system, particularly relates to a kind of deslagging water discharging device for coal mine gas extraction pipeline.
Background technology
In the work of coal mine drilling gas pumping, the ponding stored in coal rock layer unavoidably enters extraction pipeline with gas, the temperature difference that subsurface environment exists simultaneously also can form condensed water in pipeline, and the ponding that extraction exists pipeline can increase the loss of extraction negative pressure, reduces extraction running efficiency of system.Current, colliery uses tailrace to mainly contain artificial hand dynamic formula and self-action two kinds.Artificial tailrace generally discharges water thoroughly, but complex operation, and labour intensity is large, and the coal rock layer of water system prosperity is often because the discontinuous effect that causes that discharges water is bad.Automatic water drainage device is automatic draining function because realizing ponding arrival setting boundary, now be widely used in each large mining area, but existing tailrace still also exists dewatering outlet and opens insensitive, air and easily enter extraction pipeline, coal petrography drilling cuttings blocking pipeline, complex structure, high in cost of production problem, drastically influence efficiently carrying out of extraction system.
Utility model content
The utility model object is the weak point overcome in prior art, provides a kind of structure simple, with low cost, can realize methane gas extraction pipeline automatic draining, the device of regular manual deslagging.
To achieve these goals, coal mine gas extraction pipeline tailrace of the present utility model, primarily of casing, water inlet, slag-drip opening, Auto-drainage pipe is formed, water inlet is arranged on the top of casing side surface, slag-drip opening and discharge pipe line are arranged on the bottom of casing side surface, wherein casing upper surface is provided with the inlet valve that bottom is connected by push rod, inside is provided with ball float and filter screen, filter screen is inclined in casing, the order number of filter screen is 1-10, ball float connects water inlet plug by floating arm, Auto-drainage pipe comprises outfall, discharge pipe line, one way valve plug, spring, Auto-drainage pipe is connected with casing by discharge pipe line, outfall is arranged on discharge pipe line bottom, one way valve plug is connected with spring.
Beneficial effect: owing to have employed technique scheme, water inlet of the present utility model is controlled by plug of intaking, and when in water tank, water level raises, ball float raises gradually because of buoyancy, until depressed by water inlet plug by floating arm, blocks water inlet.Meanwhile, floating arm is upwards opened inlet valve by push rod, and outside air enters rapidly, and the one way valve plug that the water in casing promotes linking springs opens outfall, and the water of such casing can flow out from outfall.After water is released, ball float declines because of the water surface, and drive floating arm will to intake Sai Lakai, continue water inlet, the pipeline of inlet valve decline air-isolation guarantee extraction does not simultaneously enter air, and outfall also can be closed because spring promotes one way valve plug.After drilling cuttings enters casing in the process that discharges water, gathering near slag-drip opening under the filter screen tilted stops, regularly by manually closing water inlet valve, opening slag-drip opening valve deslagging.Methane gas extraction pipeline draining deslagging is carried out in circulation like this.Its structure is simple, with low cost, easy to operate, Be very effective, and energy is automatic draining in time, prevents extraneous gas from entering extraction pipeline simultaneously, improves gas pumping efficiency.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present utility model.
In figure: extraction pipe interface-1, water inlet plug-2, floating arm-3, casing-4, inlet valve-5, push rod-6, ball float-7, filter screen-8, water inlet valve-9, water inlet-10, slag-drip opening valve-11, slag-drip opening-12, outfall-13, discharge pipe line-14, one way valve plug-15, spring-16, Auto-drainage pipe-17.
Detailed description of the invention
Below in conjunction with accompanying drawing, an example of the present utility model is described further:
Methane gas extraction pipeline tailrace device of the present utility model, it is characterized in that: primarily of casing 4, water inlet 10, slag-drip opening 12, Auto-drainage pipe 17 is formed, water inlet 10 is arranged on the top of casing 4 side surface, slag-drip opening 12 and discharge pipe line 14 are arranged on the bottom of casing 4 side surface, wherein casing 4 upper surface is provided with the inlet valve 5 that bottom is connected by push rod 6, inside is provided with ball float 7 and filter screen 8, filter screen 8 is inclined in casing 4, the order number of filter screen 8 is 1-10, ball float 7 connects water inlet plug 2 by floating arm 3, Auto-drainage pipe 17 comprises outfall 13, discharge pipe line 14, one way valve plug 15, spring 16, Auto-drainage pipe 17 is connected with casing 4 by discharge pipe line 14, outfall 13 is arranged on discharge pipe line 14 bottom, one way valve plug 15 is connected with spring 16.
The course of work: tailrace is connected on extraction pipeline by extraction pipe interface 1, inlet valve 5 is close to water tank because of Action of Gravity Field and is ensured airtight, the one way valve plug 15 that spring 16 connects makes outfall be in closed condition, ball float 7 sinks on filter screen, water inlet 10 opened by the water inlet plug 2 connected by floating arm 3, and manual-lock slag-drip opening valve 11, opens water inlet valve 9, casing 4 is in negative pressure air-tight state, and the ponding in extraction pipeline is flowed into by water inlet 10 because of self gravitation.Along with the rising of water level in casing 4, ball float 7 raises gradually because of buoyancy, until depressed by water inlet plug 2 by floating arm 3, blocks water inlet.Meanwhile, floating arm 3 is upwards opened inlet valve 5 by push rod 6, and outside air enters rapidly, and the water in casing 4 promotes the one way valve plug 15 of linking springs 16, and open outfall 13, the water of such casing 4 can flow out from outfall 13.After water is released, ball float declines because of the water surface, drives floating arm 3 to be pulled open by water inlet plug 2, continues water inlet, and the inlet valve 5 air-isolation guarantee extraction pipeline that declines does not enter air simultaneously, and outfall 13 also can be closed because spring 16 promotes one way valve plug 15.In the process that discharges water, inevitable drilling cuttings enters casing 4, gathers near slag-drip opening 12 under the filter screen 8 tilted stops, regularly closes water inlet valve 9 by artificial, opens slag-drip opening valve 11, by slag-drip opening 12 deslagging.The rest may be inferred, carries out methane gas extraction pipeline draining deslagging by said apparatus circulation.
