Abstract
It is that carbon dioxide fracturing device expansion tube and the non-coupled disposable parts in fracturing hole, main material is made to be rubber the utility model is related to the carbon dioxide fracturing device explosion in civil explosive industry, wide 30mm, thick 2mm, a length of 500mm, at ribbon.The husky device reverse side of carbon dioxide fracturing device resistance is smooth, no special tectonic.It is 16/cm that, which there are a length of 50mm, the rubber cylinder of a diameter of 2mm, density in front,2.The husky device of carbon dioxide fracturing device resistance prevents sand from blocking jet port, and the state not coupled is formed in certain explosion space, reduces the loss of energy, reinforces fracturing effect of the carbon dioxide fracturing device to rock.
Description
Technical field
The utility model is that one on on-explosive breaking technique for rock i.e. carbon dioxide fracturing device emerging in recent years reinforces dress
Set, specially it is a kind of make carbon dioxide fracturing device expansion tube and fracturing hole formed above jet port one section not coupled room two
The husky device of carbonoxide fracturing device resistance.
Background technology
Liquid carbon dioxide phase change expansion breaking technique for rock is domestic on-explosive breaking technique for rock emerging in recent years, has peace
Entirely, the features such as environmentally friendly, economic, efficient.Just it is being considered as effective supplement of conventional blast technology application.Its low shake having, without dirt
The features such as contaminating, is safe, without slungshot, is especially suitable for the explosion of city incity.
The operation principle of carbon dioxide fracturing device is that liquid carbon dioxide compression is stored in steel cylinder first, expands tube top
Electrode is connected outside terminal bolt, and connects initiator, and bolt of the bottom with venthole, which compresses burst disk, to be sealed.Liquid dioxy
Change after carbon is excited by high temperature and 600 ~ 1000 times of volume surge is presented within the extremely short time from liquid to gaseous state, is sprayed from jet port
The high-pressure carbon dioxide air mass shot out is acted in the form of impact load forms explosion on rock.The blasting method high pressure gas
The pressure of the pressure ratio explosive blasting of body is small, about the 1/3 of black powder, and the 1/6 of nitrolite.Therefore, carbon dioxide is saved to cause
The useless consumption of energy for splitting device is of great significance for reinforcing carbon dioxide fracturing device fracturing effect.Present carbon dioxide fracturing
Device is the generation for preventing from flying pipe phenomenon, and generally by the way of being coupled between expansion tube and expansion hole, this affects carbon dioxide
The demolition effect of fracturing device does not need to whole couplings in real blasting process.Therefore, if above jet port a distance
Add a husky device of carbon dioxide fracturing device resistance, prevents sand downslide from blocking jet port, make one section of expansion tube lower part space in not
Couple state is reduced under couple state, and the energy loss generated to the powdered explosion that rock generates due to excessive explosion is reduced
The useless consumption of energy, optimizes demolition effect with this, improves work efficiency, also save the energy.
Utility model content
Sand blocks carbon dioxide fracturing device jet port in order to prevent, and the shape not coupled is formed in certain explosion space
State reduces the loss of energy, reinforces fracturing effect of the carbon dioxide fracturing device to rock, and the utility model provides one kind and can stick
Block sand above jet port to glide, forms the husky device of carbon dioxide fracturing device resistance of not coupled room.
The utility model uses following technical scheme：Its main material uses rubber, rubber strip wide 30mm, thick 2mm a length of
500mm, at ribbon.The husky device reverse side of carbon dioxide fracturing device resistance is smooth, and no special tectonic is easy to YH-308 glue firmly
Be sticked on tube wall.It is 16/cm that, which there are a length of 50mm, the rubber cylinder of a diameter of 2mm, density in front,2, block 5mm melon seeds
Stone slides, and forms non-coupled space.
Description of the drawings
Fig. 1 is the front view of the utility model embodiment.
Fig. 2 is the vertical view of the utility model embodiment.
Specific implementation mode
Carbon dioxide fracturing device expands pipe diameter in 51~95mm, and according to different sizes, the resistance of carbon dioxide fracturing device is husky
Device should be bonded in jet port at least about carbon dioxide fracturing device expansion tube two weeks or more using YH-308 glue and tube wall
At the 300mm of top, blocking sand glides.Its canoe should be clockwise, and carbon dioxide fracturing device is swollen when vibrating with gaza
The direction of tube expansion rotation is identical.
