Description
Technical field
The present invention relates to a kind of spray towards shoe, especially the biphase gas and liquid flow spray belongs to the ocean platform technical field towards shoe.
Background technology
In the marine resources development process, the use of mobile ocean platform more and more widely, some are provided with the ocean platform of shoe; When needs move ocean platform; Because the mud on shoe top makes that shoe all is difficult to pull out, existing a kind of method is to utilize High-Pressure Water outwards to spray in the shoe to dash; But spray towards effect sometimes bad, therefore be badly in need of a kind of can be fast the effective new method of removing top mud.
Summary of the invention
The purpose of this invention is to provide a kind of can improve spray towards the spray of the biphase gas and liquid flow of effect towards shoe.
The problem that the present invention will solve is that the shoe of existing ocean platform is broken through the very difficult deficiency of removing of mud in the journey in spray.
For realizing the object of the invention, the technical scheme that the present invention adopts is:
The biphase gas and liquid flow spray is towards shoe; Comprise pile, high-pressure intake pipe, high-pressure pipe, fixed block, spill spin block, helix tube, mixed flow tube, spout and shoe; High-pressure intake pipe and high-pressure pipe symmetry are installed in the fixed block; The bottom of fixed block is equipped with spill spin block, and spill spin block and fixed block are installed in the inner top of mixed flow tube.
Be provided with a helix tube in the spill spin block, current that get off above making or air-flow are rotating from helix tube and are ejecting; The helix tube upper end maintains an equal level with the spill spin block upper end mutually, and give prominence to outside spill spin block the lower end, and become 15-30 degree angle with spill spin block; Spill spin block and mixed flow tube junction are matched in clearance; The tapered body of the mixed flow tube of spill spin block bottom, tapering are the 15-20 degree, and two water outlet tracheaes of below are formed by the bullet bifurcated; Fixed block, spill spin block and mixed flow tube are stainless steel material and process; High-pressure intake pipe, high-pressure pipe, fixed block, spill spin block and mixed flow tube are installed in the pile; Two water outlet tracheaes that mixed flow tube below bifurcated forms pass from the rectangle hollow body shoe top of piles column bottom; And the formation spout, the bore of spout is less than the mouth of pipe bore of crotch.
Advantage of the present invention is: what this shoe ejected is the gas-liquid two-phase body, but also has rotation, is easy to give removing fast with the mud on shoe top through cavitation again, can improve the mobile efficient of ocean platform greatly.
Description of drawings
Fig. 1 is the front view of biphase gas and liquid flow spray of the present invention towards shoe;
Fig. 2 is the vertical view of biphase gas and liquid flow spray of the present invention towards shoe;
Among the figure: 1, pile 2, high-pressure intake pipe 3, high-pressure pipe 4, fixed block 5, spill spin block 6, helix tube 7, mixed flow tube 8, spout 9, shoe.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
As shown in the figure; The biphase gas and liquid flow spray is towards shoe; Comprise pile 1, high-pressure intake pipe 2, high-pressure pipe 3, fixed block 4, spill spin block 5, helix tube 6, mixed flow tube 7, spout 8 and shoe 9, high-pressure intake pipe 2 is installed in the fixed block 4 with high-pressure pipe 3 symmetries, and the bottom of fixed block 4 is equipped with spill spin block 5; Spill spin block 5 and fixed block 4 are installed in the top of mixed flow tube 7 inside, and gas and fluid mix the back from spout 8 ejections.
Be provided with a helix tube 6 in the spill spin block 5, current that get off above making or air-flow are rotating from helix tube 6 and are ejecting; Spill spin block 5 is a matched in clearance with mixed flow tube 7 junctions; The mixed flow tube 7 tapered bodies of spill spin block 5 bottoms, tapering are 20 degree, and two water outlet tracheaes of below are formed by the bullet bifurcated; Helix tube 6 upper ends and spill spin block 5 upper ends maintain an equal level mutually, and give prominence to outside spill spin block 5 lower end, and with 5 one-tenths 30 degree angles of spill spin block, the steam that comes out of jet can rotate in the bullet generation like this; Fixed block 4, spill spin block 5 and mixed flow tube 7 are stainless steel material and process; High-pressure intake pipe 2, high-pressure pipe 3, fixed block 4, spill spin block 5 and mixed flow tube 7 are installed in the pile 1; Two water outlet tracheaes that mixed flow tube 7 below bifurcateds form pass from rectangle hollow body shoe 9 tops of pile 1 bottom; And formation spout 8; The bore of spout 8 helps improving jet speed less than the mouth of pipe bore of crotch; Mixed flow tube 7 tops are sealed through Laser Welding and fixed block 4.
Method for using of the present invention: in high-pressure intake pipe 2, supply to supply in water under high pressure, the high-pressure pipe 3 pressure-air simultaneously; Owing to be provided with helix tube 6 in the spill spin block 5; Water or gas can make the rotation of spill spin block 5 automatic high speeds after through helix tube 6, supply water under high pressure or gases at high pressure thereby automaticallying switch to helix tube 6, and then rotation mixes steam and just goes out from the spout 8 of two water outlet tracheaes; And the formation explosion effect, can be fast the mud on top be washed away totally.
