Abstract
The utility model discloses a kind of explosion propagation device that effectively can reduce blasting fume harm, that this device is a hollow, that there is inside and outside double-walled construction annulus cylindrical shell, be circular hole (2) in the middle of inwall in the hollow part of annulus cylindrical shell, in the middle of inwall, in circular hole (2), be inserted with primacord or load powder type explosive; Be water filling cavity (1) between the inside and outside double-walled of annulus cylindrical shell, the top of water filling cavity (1) is provided with water injection hole (4), with water injection hole capping (3) on water injection hole (4).Main feature of the present utility model is when explosive charge, adds the chemical reaction that water participates in explosive charge, the toxic and harmfuls such as the carbon monoxide that explosive charge is produced and oxynitrides, only then be combined with water, form new compound, thus reduce blasting fume amount, reduce blasting fume harm.The utility model is simple to operate, safety, is specially adapted to underground explosion operation, is also applicable to surface blasting operation.
Description
Technical field
The utility model belongs to blasting technique field, specifically it relates to the explosion propagation device that when one effectively can reduce explosion, toxic and harmful (blasting fume) produces, be applicable to modern industry mining production, stone mining, city, transport development controlled blasting, use during the various explosions such as perron stripping.
Background technology
Dust, blasting fume etc. that explosion produces cause great harm to human body and environment, and therefore explosion Risk health behavior is the important topic that engineering explosion circle is studied always.
At present, industrial and mining enterprises exploit, and during the explosions such as perron stripping, all can produce a large amount of blasting fume.And during underground mine explosion, because ventilating difficulty, the blasting fume produced after explosion is difficult to diffusion, be easy to again produce blasting fume poisoning.According to statistics, in the comparatively large above accident of China's underground mine, the Poisoning choke accident proportion caused because of fire and blasting fume is more than 40%, and accident plays several and death toll and is all positioned at first of all kinds of accident of underground mine.Therefore, effectively reduce the blasting fume that explosion produces, quantity and the death toll of underground mine security incident can be reduced from source, significant.
Summary of the invention
The purpose of this utility model, is exactly the problem for easily producing a large amount of blasting fume in existing blasting method, and provides a kind of explosion propagation device that effectively can reduce blasting fume harm, use this device, the blasting fume produced when effectively can reduce explosion during explosion.
For realizing above-mentioned purpose of the present utility model, the technical solution that a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model adopts is:
That a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model is a hollow, that there is inside and outside double-walled construction annulus cylindrical shell, be circular hole in the middle of inwall in the hollow part of annulus cylindrical shell, in the middle of inwall, circular hole interpolation has primacord or loads powder type explosive; Be water filling cavity between the inside and outside double-walled of annulus cylindrical shell, the top of water filling cavity is provided with water injection hole, with water filling capping on water injection hole.
Actual when using, by topped up with water in cavity between a kind of for the utility model spaced loading demolition set inside and outside wall that effectively can reduce blasting fume harm, in the middle of inwall, circular hole inserts primacord or to be put in hole between explosive and explosive after loading powder type explosive.
After a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model adopts technique scheme, during explosion, water in water filling cavity between the inside and outside double-walled of annulus cylindrical shell is in instant of detonation, because being subject to HTHP effect, formed vaporific instantaneously, the carbon monoxide that these spray waters can produce after explosion and oxynitrides are combined, and form new compound, thus the blasting fume produced after effectively reducing explosion.
Accompanying drawing explanation
Fig. 1 is a kind of front view that effectively can reduce the explosion propagation device of blasting fume harm of the utility model;
Fig. 2 is topped up with water front view after inserting primacord before a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model uses;
Fig. 3 is a kind of top view that effectively can reduce the explosion propagation device of blasting fume harm of the utility model.
Reference numeral is: 1-water filling cavity; Circular hole in the middle of 2-inwall; The capping of 3-water injection hole; 4-water injection hole; 5-water; 6-primacord.
Detailed description of the invention
For further describing the utility model, below in conjunction with drawings and Examples, a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model is described further.
The utility model the utility model is as shown in Figure 1 a kind of effectively can reduce the front view of the explosion propagation device of blasting fume harm and composition graphs 2, Fig. 3 find out, that a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model is a hollow, that there is inside and outside double-walled construction annulus cylindrical shell, be circular hole 2 in the middle of inwall in the hollow part of annulus cylindrical shell, in the middle of inwall, in circular hole 2, be inserted with primacord 6 or load powder type explosive; Be water filling cavity 1 between the inside and outside double-walled of annulus cylindrical shell, the top of water filling cavity 1 is provided with water injection hole 4, with water injection hole capping 3 on water injection hole 4.As long as a kind of explosion propagation device that effectively can reduce blasting fume harm of the utility model opens water injection hole capping 3 before use, in the water filling cavity 1 between inside and outside double-walled, water 5 is added by water injection hole 4, in the middle of inwall, in circular hole 2, insert primacord 6 or after adding powder type explosive, this device is put between hole explosive and explosive.
Claims (1)
1. one kind effectively can be reduced the explosion propagation device of blasting fume harm, it is characterized in that: that this device is a hollow, that there is inside and outside double-walled construction annulus cylindrical shell, be circular hole (2) in the middle of inwall in the hollow part of annulus cylindrical shell, in the middle of inwall, in circular hole (2), be inserted with primacord (6) or load powder type explosive; Be water filling cavity (1) between the inside and outside double-walled of annulus cylindrical shell, the top of water filling cavity (1) is provided with water injection hole (4), with water injection hole capping (3) on water injection hole (4).
