Description
Technical field
The utility model is related to nonflame pressure release building block technique fields, relate particularly to a kind of round nonflame bleeder.
Background technology
With the development of modern industry, the potentially danger of dust explosion greatly increases, and every 3 or four years, just has big together
The dust explosion accident of type, still, many enterprises or even administrative department recognize to seem not yet the meetings such as mild flour, feed
Dust explosion occurs, and especially big dust explosion accident once occurs, often suffers heavy losses.In actual production, it is only used only
Bursting diaphragm venting of dust explosion, does not carry out explosion isolation, and the flame for generation of exploding will be transferred to other phases with pressure wave by the pipeline that is connected
Attached device causes the generation of secondary or even bigger power explosion.Flame proof technology can prevent explosion from initial position to other works
Skill cell propagation avoids the generation of " secondary " explosion or system explosion accident, to mitigate explosion disaster.Nonflame bleeder is made
It is simple in structure for a kind of mechanical passive pressure relief device, it is swift in response, it is easy for installation, it can be used for easily causing dust quick-fried
Fried occasion.
Existing nonflame bleeder is all mostly rectangular or fan-shaped, and volume is larger, is generally used for outside integrated mill
The pipeline in face, and for interior since space is limited is then not suitable for installation indoors, since the nonflame bleeder is released pressure
If the cavity surrounded by pressure release shell of advocating goes out pressure releasing by the back-fire relief net exported out, if only simple
The scale smaller of nonflame bleeder, the volume of the pressure release shell will be necessarily reduced, is reduced so as to cause its circulation, pressure
Power can not release away, and solution generates explosion in narrow space；And rectangular nonflame bleeder only has pressure release shell
Back-fire relief net above, which can be sealed with pressure release, pressure release shell by carbon steel sheet, makes surrounding from pressure release, causes pressure release effect poor.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of round nonflame bleeder, simple in structure, peace
It fills small, can be used for the installation of interior conduit, and the more existing rectangular nonflame bleeder of pressure release effect is more preferable.
The utility model specifically uses following technical scheme to achieve the goals above：
A kind of circle nonflame bleeder, including pressure release shell, back-fire relief net and bursting diaphragm；The back-fire relief net is arranged to cylinder
Body shape, the pressure release shell, bursting diaphragm are separately positioned on the both ends of back-fire relief net.
Preferably, several vertical supports for fixing back-fire relief net are provided on the pressure release shell, and on pressure release shell
Side is provided with cover board, and the cover board is integrally arranged with vertical supports upper end, and the cover plate central is provided with a protection network.Vertically
Holder and being provided with for cover board are conducive to fix, and being provided with for protection network is connected to conducive to the outlet of back-fire relief net with outside air, is conducive to
Pressure is released.
Preferably, it states on cover board at least provided with a hanging ring；When being provided with conducive to installation carrying of hanging ring, is held by and hangs
Ear is easily installed carrying.
Preferably, the back-fire relief is provided with one end of bursting diaphragm and upper and lower relation is provided with first flange and the second method on the net
Orchid, the bursting diaphragm are arranged between first flange and second flange；First flange and being provided with for second flange are conducive to anti-
Plate bursting is fixed on the opening of back-fire relief net one end.
Preferably, a gasket seal is each provided between the bursting diaphragm and first flange and second flange；Gasket seal
Setting advantageously ensure that the leakproofness of bursting diaphragm.
Preferably, the back-fire relief net is made of stainless steel filtering net structure；Back-fire relief can be reduced using stainless steel filtering net structure
The weight of net reduces cost, and improves durability.
The beneficial effects of the utility model are as follows：
1. circle nonflame bleeder setting is ingenious, installation volume is small, can be used for interior, is installed on interior conduit.
2. explosion time, blast pressure first passes around bursting diaphragm, and bursting diaphragm is shattered, and pressure enters in back-fire relief net, due to
Explosion usually can prevent flame transmission, and back-fire relief net setting is in cylinder with this flame, back-fire relief net energy knock down the flame
Shape, surrounding is unobstructed, does not form confined space, and pressure energy releases away pressure from surrounding by back-fire relief net, more existing skill
The rectangular nonflame bleeder of art only has the back-fire relief net of pressure release housing upper face that can be sealed not using carbon steel sheet with pressure release, pressure release shell
For energy pressure release, which can improve efficiency of releasing.
