Abstract
The present utility model relates generally to the automatic decompression device of a kind of mine ventilation system regulation facility, especially relates to air door.When underground coal mine generation explosion accident, this air door windward side rupture disk (6) ruptures releasing pressure automatically, and under percussive pressure effect, pressure port (1) can be swung up along bearing (3), so that air blast runs through, protects door body；After blast terminates; pressure port (1) is under gravity; the most naturally swing; the Magnet (7) fixing with downside door body fits tightly; achieve the tunnel after blast to seal, thus prevent and treat underground air movement disorder, prevent and treat inverted ventilation; protect the properly functioning of underground ventilating system, for safeguarding that the safety in production of down-hole has important practical significance.
Description
Technical field
The application relates to coal mine ventilation system regulation facility, particularly relates to air door.
Background technology
In coal mining, complete ventilating system is the premise of safety of coal mines exploitation, and the effect of air door regulates well exactly
Lower ventilation, distribution down-hole air quantity, keep ventilating system completely stable, in order to provide fresh air for down-hole.Automatic decompression device
Mainly it is installed on air door, it is also possible to be installed on other attached mine ventilation facilities, such as on explosion proof door.Its Main Function has
The following aspects: when (1) mine normally ventilates, automatic decompression device can keep (ventilating system regulation facility) airtight
Property, it is to avoid Air escape branch；(2) when down-hole is once occur gas or coal-dust explosion, by the percussion of down-hole high pressure blast, ore deposit
Automatic decompression device on well ventilation equipment, especially air door can open pressure release moment, and the shock wave preventing blast from producing breaks
Ruin ventilation equipment；(3) after mine generation gas or coal-dust explosion, automatic decompression device can reset in time, recovers ventilating system
Integrity, prevents from causing distinguished and admirable disorder owing to ventilation equipment damages.
By the investigation and analysis to many mine explosion accidents, current mine ventilation facility, especially air door is primarily present
Following two defect:
(1) due to the uncertainty of well shooting accident intensity, when the impact wave that blast produces is too strong, ventilation sets
Executing, especially air door is highly susceptible to severe impact and deforms or destroy, and can cause distinguished and admirable disorder occur, it is more likely that can cause
Air escape branch, even inverted ventilation, and then in causing tunnel and work surface is for hypoxgia, this is by the life of serious threat down-hole trapped personnel
Life safety.(2) facility, especially air door of coal mine ventilation system regulation now, is fitted without protecting mine ventilation system to adjust
, once there is gas or coal-dust explosion in the device of the safety relief of joint facility, powerful shock wave can destroy ventilating system regulation
Facility, destroys coal mine ventilation system, and serious threat is to the safety in production in colliery.
The potential safety hazard that above-mentioned two defect necessarily mine is great, therefore, improves the safety and reliability of pressure relief device,
Significant to mine safety production.
Summary of the invention
The purpose of the application is the deficiency overcoming existing ventilating system pressure relief device, proposes a kind of mine ventilation system regulation
The automatic decompression device of facility, the automatic decompression device being particularly applied on air door.
The technical scheme is that a kind of mine ventilation system regulation facility automatic decompression device, it include by
Permanent magnet, sealing pressure port and the combination pressure relief device of rupture disk composition, it is characterised in that permanent magnet is fixing inlays installation
In door body, above sealing pressure port, overlap one can be around the live bearing of center rotating again；On the right side of described pressure relief device
Rupture disk clamper is fixedly mounted in door body, seals rupture disk two ends and is clamped in rupture disk clamper fixing, rupture disk
It is to be processed by the sheet material easily crushed by blast impulse.
The automatic decompression device of described mine ventilation system regulation facility, pressure port therein is by blast impulse
During the effect of ripple, can upwards rotate freely along the live bearing of its upper end, and after shock wave is in the past, pressure port is permissible
The most sagging under gravity, can fit tightly with the permanent electric Magnet of bottom, thus maintain the complete of ventilating system
Property.
In order to prevent leaking out of contact surface, at pressure relief device contact surface, it is provided with encapsulant.
Operation principle and providing the benefit that: explosion time occurs in down-hole, and it is right that blast arrives first at automatic decompression device
End rupture disk, rupture disk, by impact rapid disruption, and then releases a part of pressure, it is to avoid ventilation equipment, especially air door,
Deformation failure when by intense impact；After on the left of automatic decompression device, pressure port is opened under the effect of impact wave simultaneously
All pressure releases；After explosion accident, left side pressure port naturally droops under gravity, and is fixed on bottom ventilation equipment forever
Magnet contact, closely fits under the graviational interaction of magnetic field, thus safeguards ventilation equipment, especially the sealing of air door for a long time, maintains
The stablizing of underground ventilating system；Gas explosion is often with repeatedly exploding, when subsequent explosion occurs, on the left of automatic decompression device
Pressure port, normally-open pressure release, after blast terminates, maintain the sealing of ventilating system all the time, thus recover ore deposit as soon as possible
Well ventilates, and ensures the life security of down-hole trapped personnel to greatest extent；Quick-fried to rupture again while normal ventilation afterwards
Fragmentation is replaced, and recovers original serviceable condition.
Accompanying drawing explanation
Fig. 1 is the enforcement schematic diagram of the present invention
In accompanying drawing: 1, pressure port；2, fixing device；3, live bearing；4, door body；5, rupture disk clamper；6, seal quick-fried
Fragmentation；7, permanent magnet；8, encapsulant.
Detailed description of the invention
Enforcement to the present invention is described in further detail below in conjunction with the accompanying drawings:
As it is shown in figure 1, the automatic decompression device of a kind of mine ventilation system regulation facility, it includes by live bearing 3
With the left side door body of pressure port 1 composition, pressure release door body in left side, under the effect of fixing device 2, is tightly secured in the door body of upside,
Right side door body is the sealing rupture disk 6 clamped by rupture disk clamper 5 and other assemblies, and downside door body fixes one piece of stable magnetic field
And the permanent magnet 7 that can fit tightly with pressure port；
Described pressure release door body is when being stimulated by explosion wave, it is possible to be rotated up around live bearing 3 rapidly, thus
Open pressure port pressure release；After blast terminates, pressure port 1 is the most sagging, with downside door body permanent magnet 7 under gravity
Contact, seals under the influence of a magnetic field；
In order to prevent left side pressure port 1 changing of the relative positions mutual with permanent electric Magnet 7 and the leaking out of contact surface, it is provided with encapsulant 8.
In order to prevent leaking out of contact surface, at pressure relief device contact surface, it should be provided with encapsulant.
