Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to shown in Fig. 1-2, a kind of gravity explosion relief door, including pipeline 1 and door-plate 7, pipeline 1 can be beaten relative to door-plate 7
On or off is closed, and the top of pipeline 1 is provided with fixed frame 2, and the both ends of fixed frame 2 are provided with the first buckle 3, the first buckle 3 and the
Two buckles 4 are adapted, and axial trough 10 is arranged in 4 inside of the second buckle, and axial trough 10 is adapted with shaft 5, the end adjacent position of shaft 5
It is provided with switch block 11, bracket 6 is fixedly installed on the lateral wall of pipeline 1, one end of shaft 5 is provided with fixture nut 9, door-plate 7
Top bracket 6 is connected to by shaft 5.
As a kind of technical optimization scheme of the utility model, the edge of door-plate 7 is provided with gasket 8, is letting out
After the completion of pressure, door-plate 7 returns to original position under the effect of gravity, due to the sealing function of gasket 8, can prevent from leaking out.
As a kind of technical optimization scheme of the utility model, bracket 6 is flexibly connected with shaft 5, by by bracket 6 with turn
Axis 5 be flexibly connected can well door-plate 7 around the shaft 5 relative to pipeline 1 rotate.
As a kind of technical optimization scheme of the utility model, the area of door-plate 7 is greater than the area of pipeline 1, by by door
7 area of plate is set greater than the area of pipeline 1, therefore door-plate 7 has biggish area that can resist shock wave, avoids door-plate 7
Damage.
As a kind of technical optimization scheme of the utility model, door-plate 7 or/and pipeline are that steel material is made, table
Face is coated with zinc rich primer and metal fluorocarbon coating.Door-plate 7 is made of channel steel, and door-plate 7 and pipeline 1 are made by above-mentioned material,
It can make explosion relief door that there is good intensity and shock resistance, prevent from damaging, the repeatable dismounting of explosion proof door can be made to use, drop
Low use cost, improves use effect of explosion relief door.
When the utility model is used, by being disposed relative to the door-plate 7 that pipeline 1 is openable or closes, at system
In operating status, deduster internal pressure is lower than extraneous normal atmosphere (An), negative pressure state is in, by pressure difference and self gravity shadow
It rings, door-plate 7 makes pipeline 1 be in the state for closing sealing under the action of gasket 8；Unit is out of service, door-plate due to only by
Its own gravity influences, and is in close state；When catching fire in unit, unit internal temperature is increased, and pressure rises, when interior extraneous pressure
When difference is greater than its spontaneous gravity of door-plate, door-plate 75 flicks around the shaft relative to pipeline 1, carries out venting of dust explosion.Pressure inside unit is logical
Cross door-plate 7 moment pressure release, after the completion of pressure release, door-plate 7 under the effect of gravity can automatic quick closedown so that personnel are not at the scene
Can self-closed flame range, ensure that personnel safety.Fire occurs inside unit and needs to close for the utility model explosion relief door
When flame range, explosion venting area is served as using entire door-plate 7, it is simple in construction, easy to disassemble and assemble, use cost is reduced, can effectively be reached
Venting of dust explosion optimum efficiency, door-plate 7 can effectively be let out except explosion wave, guaranteed that unit does not damage, after the completion of pressure release, can safely and fast be sealed
Flame range is closed, makes field personnel have the sufficient time quickly to flee from the closed area that may be exploded, is transferred to safety zone, does
To can quick closure flame range and personnel safety.7 lower section of door-plate is opened outward, automatically replies closing using gravity, no
By any venting of dust explosion driving device, the dangerous risk of driving device is eliminated.
