The utility model provides an explosive burns protector makes the explosive burning can obtain the supervision to avoid old and useless explosive to burn the piece and the harm of flue gas to work that produce.

Referring to fig. 1 to 3, the explosive incineration prevention apparatus of the present embodiment includes: the cover body 100, the metal mesh 200, the smoke guide cylinder 300, the smoke guide mechanism 400 and the rupture disk isolating component 500.

The housing 100 is placed on the ground for housing explosives to be incinerated, the inner diameter of the housing 100 is increased from top to bottom, the housing 100 has a polygonal sidewall such as: the side walls of the cover 100 may be four sides, six sides or eight sides, in this embodiment, the side walls of the cover 100 are designed as four sides, please refer to fig. 4, one side wall of the cover 100 is provided with a vent 110, and the side wall provided with the vent 110 faces the wind, the other side wall of the cover 100 is provided with an igniter throwing opening 120 for throwing ignited cotton yarn or firewood from the throwing opening 120 into the cover 100 to ignite the explosive to be incinerated, and a screw knob plug 130 is further disposed in the igniter throwing opening 120 for plugging the throwing opening 120.

The metal net 200 is detachably fixed to a sidewall of the cover body 100, and in particular, the metal net 200 is fixed to the sidewall where the ventilation opening 110 is formed, and covers the ventilation opening 110.

When the explosive is burnt, natural wind passes through the metal mesh 200 and passes through the ventilation opening 110, and air is continuously conveyed into the enclosure 100, so that the explosive in the enclosure 100 is fully burnt, and fragments or particles generated by the combustion of the explosive are isolated in the enclosure 100 by the metal mesh 200.

The smoke guide tube 300 is provided at the top of the housing 100 and communicates with the top of the housing 100, and the smoke guide tube 300 serves to mount the smoke guide mechanism 400 and the rupture disc barrier assembly 500 and guide smoke generated by the combustion of the explosive in the housing 100 upward.
