Description
Technical field
Venting of dust explosion building board field is the utility model is related to, more particularly to a kind of venting of dust explosion plate.
Background technology
Potential danger blast area be present in fields such as chemical industry, pharmacy, military project, aeronautical manufactures, if running into burst blast feelings
Condition, fragment caused by blast disperse to surrounding.Instant of detonation, which produces larger impulsive force, causes fragment to have during flying out
There is larger kinetic energy, fragment can continue to move with faster speed, may damage neighbouring equipment and pipeline, trigger larger danger
Danger.
Venting of dust explosion plate is arranged in building, and when blast occurs, venting of dust explosion plate shape, can be with abrupt release critical pressure into polylith fragment
Power, in order to avoid impact is directly acted on building caused by blast, reduce building secondary damage.But due to some fragments
Comparatively fine, the scope spread after formation fragment is wider, still the pipeline close to venting of dust explosion plate or personnel may be caused to hinder
Evil.
Utility model content
The purpose of this utility model is to provide a kind of venting of dust explosion plate, netted protective cover is set inside it, reduces venting of dust explosion plate
The range of scatter formed after fragment.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of venting of dust explosion plate, including
The first fiber composite, the second fiber composite and the mat set gradually from interior to outdoor；Mat include with
The fixed part and the buffer part being folded with is integrally formed with fixed part that the edge of second fiber composite is fixed.
Using above technical scheme, indoor generation explosion time, venting of dust explosion plate is advance by blast impulse, the first fiber composite
It is broken, involve afterwards to the second fiber composite, mat and then impacted and opening of taking advantage of a situation.
The fragment that first fiber composite and the second fiber composite are formed by external impact falls in mat,
The fragment that the mat opened is formed to the first fiber composite and the second fiber composite provides buffering, can stop its continuation
Motion.Even if the excessive mat damage of explosive forces, mat can still act as the first fiber composite and second
The fragmented buffering of fiber composite explosion shape.Using mat, reduce venting of dust explosion plate and formed fragment continuation by external impacts
To external diffusion.
Further, the size of mat is 2.5-3 times of the second fiber composite size.
Using above technical scheme, the size of mat is larger, and the center section of mat is more, and this is partially folded
Set.When venting of dust explosion plate is by external impacts, the mat of folding opens, to venting of dust explosion plate shape into partial piece formed it is slow
Punching, in case fragment range of scatter is too big.
Further, the aperture size of mat is 1-2cm.
Using above technical scheme, the aperture of mat is arranged to 1-2cm, it is ensured that mat has certain
Power, while most of fragment is formed and stopped, further reduce fragment range of scatter.
Further, the side of the first fiber composite and the fitting of the second fiber composite is provided with fungus resistant coating.
Using above technical scheme, fungus resistant coating is applied on the inside of the first fiber composite and the second fiber composite, is absorbed
Moisture in venting of dust explosion plate, in order to avoid venting of dust explosion intralamellar part becomes tide, influence the mechanical property of the first fiber composite and the second fiber composite
Energy.
Further, mat sets layer of polyurethane away from the side of the second fiber composite.
Preferably, the thickness of layer of polyurethane is 3mm.
Using above technical scheme, during normal mounting, mat is close to outdoor side increase layer of polyurethane, polyurethane
Layer can be as the outer protective layer of mat, in order to avoid mat scatters.During by external impacts, layer of polyurethane can be with
As third level buffer area, layer of polyurethane mass ratio is lighter, that is, forms it into some fragments, also will not be to the building of outside
Or personnel damage.
Further, the thickness of the first fiber composite and the second fiber composite is 9mm.
Using above technical scheme, the thickness of the first fiber composite of control and the second fiber composite, in the thickness model
In enclosing, the cost of the first fiber composite and the second fiber composite is relatively low, and is formed fragment by easy after external impacts,
Being capable of abrupt release pressure.
Further, some through holes are opened up in array on the second fiber composite.
Using above technical scheme, through hole is opened up on the second fiber composite, increases the flexibility of the second fiber composite, its
One layer of cushion can be used as.First fiber composite is formed fragment by external impacts, and air-flow passes through through hole, makes mat
There is opening trend in advance.
In summary, the utility model has the advantages that：
1st, the agent structure of venting of dust explosion plate includes the first fiber composite and the second fiber composite, leaves buffering therebetween
Cavity, the second fiber composite sets mat away from the side of buffer cavity, when the first fiber composite and the second fiber
Composite bed by external impacts it is broken after, mat is taken advantage of a situation opening, can be continued with stop portions fragment to external diffusion.
2nd, some through holes are opened up on the second fiber composite, it has certain flexibility, can alleviate the first fiber composite
The broken fragment formed.
