Light composite explosion-proof fire-extinguishing barrel

Abstract

The invention provides a light composite explosion-proof fire-extinguishing barrel. The whole light composite explosion-proof fire-extinguishing barrel is made of composite materials, and is able to cause no secondary damage at the moment of explosion and ensure connection strength between a barrel bottom and a barrel body, so that the explosion-proof barrel is reliable as a whole; and meanwhile,fire extinguishing performance is achieved, and fire extinguishing can be effectively performed while explosion is prevented. The light composite explosion-proof fire-extinguishing barrel comprises atop cover, the barrel body and the barrel bottom, wherein the openable top cover is arranged at the top opening of the barrel body, and the barrel bottom is connected to the bottom opening of the barrel body; the top cover comprises a top cover shell and a fire-extinguishing agent filled inside the top cover shell; when explosives in the explosion-proof fire-extinguishing barrel explode, the top cover shell is open to spray the fire-extinguishing agent out; the barrel body sequentially comprises a barrel body fireproof layer, a heat insulation layer, a fixing ring layer and a barrel body bulletproof layer from inside to outside; the barrel bottom sequentially comprises a barrel bottom bulletproof layer and a buffer layer from top to bottom; and the top cover shell, the barrel body fireproof layer, the heat insulation layer, the fixing ring layer, the barrel body bulletproof layer, the barrel bottom bulletproof layer and the buffer layer are all made of nonmetal composite materials.

Description

technical field [0001] The invention relates to an explosion-proof fire extinguishing barrel, in particular to a miniature lightweight composite explosion-proof fire extinguishing barrel, which belongs to the technical field of public safety. Background technique [0002] The explosion-proof barrel is a kind of equipment used for temporary disposal of explosives. It is generally a barrel structure with a barrel bottom. When in use, the explosives are picked into the barrel through the explosion-proof rod for disposal. The connection strength will directly affect the performance of the explosion-proof barrel. Explosion-proof barrels made of conventional metal materials are easier to form. The bottom of the barrel and the barrel body can be welded or integrally formed, such as casting, turning, etc.; however, explosion-proof barrels made of metal are heavy and easy to form.

AI Technical Summary

Problems solved by technology

Explosion-proof barrels made of conventional metal materials are easier to form. The bottom of the barrel and the barrel body can be welded or integrally formed, such as casting, turning, etc.; however, explosion-proof barrels made of metal are heavy and easy to form. Disadvantages such as secondary fragmentation

Composite materials are also used as the intermediate interlayer material of explosion-proof barrels, but this kind of explosion-proof barrel still has the disadvantage of being relatively heavy and easily forming secondary fragments

And generally such explosion-proof barrels do not have a fire extinguishing function, and the flame will burst out from the explosion vent, ignite other flammable substances, and cause a fire situation.

[0003] Explosion-proof equipment made of composite materials is a current explosion-proof trend. The explosion-proof equipment completely adopts composite material structure, which has the characteristics of light structure and no secondary fragments. However, for explosion-proof barrels with barrel body and barrel bottom, composite During the preparation of materials, since the molding of composite materials generally requires hot pressing of the corresponding molds, the production process is relatively complicated, and there is a problem of insufficient connection strength between the bottom of the barrel and the barrel body

If the material is simply cemented or the barrel is sewn on the barrel, its strength cannot meet the corresponding requirements.

[0004] At the same time, because general fiber composite materials cannot withstand high temperature for a long time, for explosives such as explosives, if the fire cannot be extinguished in time, some fibers may be melted or burned, which will affect the explosion-proof performance of the explosion-proof equipment.
