Abstract
A compression-resistant pasty or liquid explosive column comprises a shock source explosive column and a compression-resistant barrel (3). The explosive column is mainly formed by a casing (1) and pasty or liquid explosives (2), the compression-resistant barrel (3) is placed inside the casing (1), a plurality of holes (3-1) are arranged on the barrel wall, and the pasty or liquid explosives (2) are arranged inside the casing (1) and the compression-resistant barrel (3). The compression-resistant pasty or liquid explosive column has the advantages that the compression-resistant barrel can have a function of preventing the barrel-shaped casing from deforming when the barrel-shaped casing is compressed to deform as the compression-resistant barrel is placed inside the casing of the explosive column, thereby improving compression-resistant property of explosive column products.
Description
Technical field
The utility model relates to the explosive column field.
Background technology
At present, paste or the main tubular shell of liquid explosives powder column (comprise plastic casing or film, paper web), paste or liquid explosives and detonator seat (film, the paper web powder column does not need) form, paste or liquid explosives and detonator seat are placed in the housing, its weak point is because the tubular shell of powder column is with vinyon blowing or injection molded, housing wall is thinner, crushing resistance is relatively poor, only be suitable for powder type explosive, as be used for paste or liquid explosives then because its crushing resistance is relatively poor, in use, the distortion that is flattened of the easy pressurized of tubular shell, become oval tubular by cylindric, distortion is excessive when shriveling, and its effective dimensions can cause can not detonating and propagation of explosion during less than cut off diameter.
The utility model content
The purpose of this utility model is exactly at existing paste or the relatively poor deficiency of its crushing resistance of liquid explosives powder column, and a kind of pressure resistant type paste or liquid explosives powder column are provided.
The utility model comprises powder column, and powder column mainly is made up of housing (1), paste or liquid explosives (2), withstand voltage tube (3) and detonator seat (film, paper web powder column do not need).It is characterized in that inside is provided with withstand voltage tube (3), withstand voltage tube (3) is placed in the housing (1), and its barrel is provided with several holes (3-1), and withstand voltage tube (3) is cylindric, oval tubular, square tube shape or many ribs tubular.Withstand voltage tube (3) can be replaced by the net tube.The compression strength of withstand voltage tube (3) is greater than 0.3MPa.
The utility model has the advantages that: owing in the housing of powder column, be placed with withstand voltage tube, during the tubular shell compressive deformation, withstand voltage tube can play and stop tubular shell too to be out of shape, and makes the effect of effective dimensions less than cut off diameter, improved the resistance to pressure of powder column product, to guarantee that powder column normally detonates.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the withstand voltage barrel structure schematic diagram of webmaster formula.
The specific embodiment
(comprise plastic casing or film, paper web at existing powder column housing, diameter 62mm) the withstand voltage tube 3 of 1 interior placement, withstand voltage tube 3 usefulness high-strength PVC plastics are made (diameter 40mm, wall thickness 2.5mm), its length is slightly less than housing (1), open several equally distributed circular holes (diameter 20mm) 3-1 on withstand voltage tube barrel, withstand voltage tube communicates with housing (1) by hole (3-1).The also available net tube of withstand voltage tube (3) (hole on the barrel is netted).Paste or liquid explosives (2) are placed in housing (1) and the withstand voltage tube (3).Withstand voltage tube 3 compression strength are greater than 0.3MPa.
Claims (4)
1. pressure resistant type paste or liquid explosives powder column comprise explosive-source explosive post, and this powder column mainly is made up of housing (1) and paste or liquid explosives (2); It is characterized in that it also has withstand voltage tube (3), withstand voltage tube (3) is placed in the housing (1), and its barrel is provided with several holes (3-1), and paste or liquid explosives (2) are placed in housing (1) and the withstand voltage tube (3).
2. pressure resistant type paste according to claim 1 or liquid explosives powder column is characterized in that withstand voltage tube (3) is cylindric, oval tubular, square tube shape or many ribs tubular.
3. according to described pressure resistant type paste of claim 1 or liquid explosives powder column, it is characterized in that withstand voltage tube (3) can be replaced by the net tube.
4. pressure resistant type paste according to claim 1 or liquid explosives powder column is characterized in that the compression strength of withstand voltage tube (3) is greater than 0.3MPa.
