Description
Technical field
The utility model is related to gas pipeline Auto-drainage jettison gears under mine, and electricity cannot be connect by being specially adapted to underground
Realize automatic draining, specially gas discharge in mine negative pressure automatic drainage device in place.
Background technology
During coal mine gas drainage, formed because each place difference variation of underground coal mine is big, in extraction system pipeline big
The condensed water of amount, in addition, since sandstone crevice water and this coal seam are aqueous, hole pumping and mining can also extract a large amount of Drilling Water out no matter
It is that Drilling Water or condensed water are present in gas pipeline, the normal operation that will all influence extraction system increases extraction resistance,
Extracting result is reduced, shows as the increase of system negative pressure, pressure difference reduces, and the increased illusion of gas density occurs.When ponding is serious, very
To extraction is caused to be interrupted, gas exceeding limit accident is caused.Therefore, it is hidden to become the considerable safety that influence system is stablized for extraction system ponding
Suffer from, the system work that discharges water is always an emphasis, while is also a difficult point.
For a long time, ponding is mainly discharged water using artificial tailrace in methane gas extraction pipeline, heavy workload, and labour is strong
Degree is high, and cannot achieve the purpose that continuously to discharge water, and causes ponding in pipeline that cannot drain in time, influences gas pumping.At present,
The automatic water drainage device for having many types is applied to mine gas extraction system, but fail to be pushed away comprehensively in mine extraction system
Wide application, is primarily present problems with：1st, the ability that discharges water is small, and the place big to the ponding effect that discharges water is not caught up with.2nd, service life
Short, due to mine water degree of calcification height, traditional automatic water drainage device component precision is high, and hard water easily causes component failure, causes automatic
Tailrace cisco unity malfunction.Developing a kind of practical automatic bleeder for being not required to connect electricity seems very urgent.
Invention content
The gas pipeline jettison gear that coal mine uses at present is mainly based on manual water drain, also negative pressure automatic draining
Device.All there are fluctuation of service, high failure rates for both modes, it is impossible in time emit the ponding in gas pipeline
Problem.The utility model in order to solve this problem, provides gas discharge in mine negative pressure automatic drainage device.
The utility model adopts the following technical scheme that realization：Gas discharge in mine negative pressure automatic drainage device, packet
Water tank and control cabinet are included, water tank is equipped with water inlet pipe, logical air pipe and discharge tube, the first pneumatic butterfly is provided on water inlet pipe
Valve leads on air pipe and discharge tube and is both provided with the second Pneumatic butterfly valve, and air source filter, the first Pneumatic timer are equipped in control cabinet
Device and the second Pneumatic timer device, air source filter are connected by pipeline with the first Pneumatic timer device and the second Pneumatic timer device respectively
It connects, the first Pneumatic timer device is connect by pipeline with the first Pneumatic butterfly valve, the second Pneumatic butterfly valve, and the second Pneumatic timer device passes through pipe
Road is connect with the first Pneumatic butterfly valve, the second Pneumatic butterfly valve.
Time opening and closing of the utility model using Pneumatic timer device control Pneumatic butterfly valve.Water inlet pipe connects on water tank
Gas pipeline, air source filter connect underground compressed air, when the first Pneumatic butterfly valve of water inlet pipe is opened, drainpipe and logical air pipe
Second Pneumatic butterfly valve is closed；When the first Pneumatic butterfly valve of water inlet pipe is closed, drainpipe and the second Pneumatic butterfly valve of logical air pipe are opened.
Electricity need not be connect, only need to connect air source, can realize that fixed interval discharges water, interval time can arbitrarily be adjusted in a certain range.
The beneficial effects of the utility model are：Electricity need not be connect and realize automatic draining, prevent from connecing the security risk that electricity is brought, change
It has been apt to underground work environment, especially in highly gassy mine, there is very high safety benefit and social benefit.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
In figure：1- water tanks, 2- control cabinets, 3- water inlet pipes, 4- lead to air pipe, 5- discharge tubes, the first Pneumatic butterfly valves of 6-, 7-
Second Pneumatic butterfly valve.
Specific embodiment
Gas discharge in mine negative pressure automatic drainage device, including water tank 1 and control cabinet 2, set on water tank 1 there are two into
Water pipe 3 leads to air pipe 4 and discharge tube 5, is provided with the first Pneumatic butterfly valve 6 on water inlet pipe 3, leads on air pipe 4 and discharge tube 5 all
The second Pneumatic butterfly valve 7 is provided with, air source filter, the first Pneumatic timer device and the second Pneumatic timer device, gas are equipped in control cabinet 2
Supply filter is connect by pipeline with the first Pneumatic timer device and the second Pneumatic timer device respectively, and the first Pneumatic timer device passes through pipe
Road is connect with the first Pneumatic butterfly valve 6, the second Pneumatic butterfly valve 7, and the second Pneumatic timer device passes through pipeline and the first Pneumatic butterfly valve 6,
Two Pneumatic butterfly valves 7 connect.
When it is implemented, Pneumatic butterfly valve has selected the Pneumatic butterfly valve that promoting menstruation is 50mm, ensure that bleed pressure drops to 0.2Mpa
When, gas pipeline negative pressure can normally open and close when reaching -30Kpa, water storage tank body will not deform；Control tank shell is adopted
With stainless steel material, using rubber seal at enabling, ensure that device will not intake.
