Core.
Preferably, spacer ring is installed at the top of the square tube, the square tube side is equipped with connecting pin, and the explosion-proof core passes through
The spacer ring and the connecting pin are connect with the square tube.
Preferably, the rupture disk side is connected with blast signal line.
Preferably, the upper cover is detachably connected with the case top.
Preferably, there are four the gasket is set, and it is distributed in the both sides of the rupture disk two-by-two.
The advantageous effect that the utility model is reached is：The utility model has
1. when dirt equipment or dust pipeline work normally, rupture disk can stop dust leakage.
2. when cleaner or dust pipeline explosion time, this technology can make dust explosion flame pass through back-fire relief sieve to extinguish
Fall.
3. lower clamped design has gasket, it can prevent rupture disk during negative pressure from damaging.
4. equipment and control room joint control, effectively reduce explosion hazard.
Description of the drawings
Attached drawing is used to provide a further understanding of the present invention, and a part for constitution instruction, with this practicality
Novel embodiment for explaining the utility model, does not form the limitation to the utility model together.In the accompanying drawings：
Fig. 1 is a kind of structure diagram of cylindrical shape nonflame explosion venting device of the utility model.
In figure：1- bolts, 2- clamping bottom plate, 3- rupture disks, 4- gaskets, 5- nuts, 6- housings, the explosion-proof cores of 7-, 8- square tubes,
9- connecting pins, 10- spacer rings, 11- upper covers, 12- blast signal lines.
Specific embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent
Embodiment is selected to be only used for describing and explaining the present invention, is not used to limit the utility model.
As shown in Figure 1, a kind of cylindrical shape nonflame explosion venting device, including device body, described device body bottom portion is equipped with
Bottom plate 2 is clamped, rupture disk 3 is equipped between two clamping bottom plates 2, between the rupture disk 3 and two clamping bottom plates 2
It is fixedly connected by bolt 1 with nut 5, gasket 4, the clamping bottom is installed between the rupture disk 3 and the clamping bottom plate 2
2 top of plate is equipped with housing 6, and upper cover 11 is arranged at 6 top of housing, and 11 bottom of upper cover is equipped with square tube 8, the side
Explosion-proof core 7 is installed inside pipe 8.
8 top of square tube is equipped with spacer ring 10, and 8 side of square tube is equipped with connecting pin 9, and the explosion-proof core 7 passes through
The spacer ring 10 and the connecting pin 9 are connect with the square tube 8, and spacer ring 10 passes through square tube 8, are formed a cylindrical shape and are extinguished module
Component.
3 side of rupture disk is connected with blast signal line 12, is connect, passed through with electric-control system by blast signal line 12
Electric-control system remote control effectively reduces explosion hazard.
The upper cover 11 is connect with 6 top side detachable of housing, easy to disassemble.
There are four the gasket 4 is set, and it is distributed in the both sides of the rupture disk 3 two-by-two, by setting gasket 4, sealing effect
Fruit is good, and can prevent rupture disk 3 during negative pressure from damaging.
Specifically：A kind of cylindrical shape nonflame explosion venting device, when rupture disk 3 reacts simultaneously to the detonation pressure of accelerated accumulation
It is opened under 0.01MPa pressure to discharge the pressure, as the fireball formed is by open rupture disk 3, it is by housing
6th, the cylindrical shape formed between explosion-proof core 7, square tube 8, spacer ring 10 and upper cover 11 is extinguished modular unit and is stopped, mounted on stainless steel
Stainless steel precision fine-structure mesh in frame carrys out knock down the flame as three-dimensional flame trap, extinguishes the flame and hot gas of module containment detonation, with
And by the burning for opening explosion proof door and unburned dust, three-dimensional mesh screen design may act as radiator, be prevented in middle section
Explosion, and the pressure wave and dust discharged by venting of dust explosion is absorbed, although the fireball temperature of dust explosion can be easily reached 500 DEG C,
But the huge surface area for extinguishing module quickly can carry out being cooled and maintained at 100 DEG C of temperature hereinafter, this so that system is all
The temperature change enclosed can be neglected, due to can knock down the flame, containment dust and control pressure and temperature, system can be used for room
Interior any need avoids the place that venting of dust explosion impacts.
Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it can still modify to the technical solution recorded in foregoing embodiments or to which part technical characteristic
Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
