Abstract
The utility model discloses an explosive device which comprises a plastic closed container filled with a gas and a heating component is arranged inside the container. The explosive device is placed inside the blast hole of the rock or the stratum to be exploded; the heating component is allowed to heat and the gas in the plastic closed container is heated to expand rapidly under pressure; when the pressure exceeds the pressure limit of the plastic container, the plastic container is broken and the high-pressure gas is released rapidly, thereby exploding the rock or the stratum surrounding the blast hole. The whole explosion process is controllable. The explosive device has the advantages of safe operation, convenient use and no environmental pollution. Under the condition of the same explosion effect, the cost is reduced to 1/3 of the prior explosive blasting.
Description
Technical field
The utility model relates to a kind of destructor that is used for explosions such as rock or stratum.
Background technology
At present rock or the stratum explosive method that excavates, adopt in the construction generally is that the blast hole the inside explosion that explosives such as explosive are placed on prior probing is come fractured rock or stratum.But well-known, explosive is a kind of breakneck chemical substance, has very many potential safety hazards in production, transportation, keeping, use.And blasting process often has uncontrollable phenomenon, and crossing of producing in the local blasting process materials such as rock that strong impact force excites splash and hear of when hurting sb.'s feelings.And very big pollution has also been caused to air, the atmospheric air ambient around having influenced in explosive burning back.
The utility model content
The technical problems to be solved in the utility model provides a kind of safety of controlling, destructor easy to use, that cost is low.
For solving the problems of the technologies described above, the utility model comprises a plasticity closed container, is provided with gas and heater block in the container.
Adopt above device, place it in the blast hole, make the heater heating, be enclosed in the gas of plastic container the inside, the back pressure that is heated sharply expands, and after pressure surpassed the compression resistance of plastic container, plastic container broke, gases at high pressure gush rapidly, thereby rock or stratum around the broken ring, the size of its force of explosion can be adjusted as required, as selecting the bigger plastic container of compression resistance, improve the heating-up temperature in the container, make the gas pressure of explosion bigger, also can improve the initial gas pressure of destructor the inside filling, initial gas pressure is high more, under same heating-up temperature, the gas pressure of explosion is also big more.Above-mentioned airtight plastic container can be that all can produce plastic deformation, the container of certain yield strength is arranged.As canister, rubber container, plastic containers, gas can adopt air or other gas commonly used, as inert gas, hydrogen, nitrogen etc.
As a kind of improvement, described plasticity closed container is airtight plastic containers.The plastic containers low price, specification is many, selects face width, gathers materials on the spot easily, as long as can seal, have certain plasticity, energy pressure-bearing.
As a kind of improvement, described gas is gases at high pressure, and the compression resistance of described plasticity closed container and the pressure of gases at high pressure are suitable, as selecting the high-pressure plastic container, and as high-voltage tube, or the pressure-resistant plastic container.Adopt gases at high pressure, under same heating-up temperature, the gas pressure of explosion is big more, and demolition effect is good more.The pressure of above-mentioned gases at high pressure can be selected arbitrarily, as the 2-100 kgf, but can select the 2-20 kgf under conventional, is preferably the 5-8 kgf.
As a kind of improvement, described heater block comprises resistance wire, and described resistance wire is connected with the external power cord of hermetically passing plasticity closed container.The resistance wire heating is fast, and it is effective to detonate.After the blast, power line disconnects, and power supply and resistance wire are isolated.
As a kind of improvement, also be placed with the second airtight plastic container in the described plasticity closed container, described heater block is placed in the second airtight plastic container, is filled with liquid in the second airtight plastic container, can be water or alcohol or gasoline.When opening heater, evaporation constantly produced steam after the water of filling was heated in the second airtight plastic container, along with adding ambassador's second plastic container, steam pressure breaks, the energy that the water explosion produces sharply increases the gas pressure in the plasticity closed container, and the plasticity closed container is broken, gases at high pressure and water under high pressure gush, thereby strengthen the rock on every side or the broken ring power on stratum, and demolition effect is better.Be placed on the heater block in the water, preferably adopt the hollow metal tube of making by Heat Conduction Material, be provided with in the metal tube by insulator ring around resistance wire, resistance wire is connected with the external power cord of the hermetically passing second airtight plastic container, plasticity closed container respectively.
