Description
Technical field
The present invention relates to fluid technique fields, more particularly to are sprayed by a kind of submerged polylinker cavitation of principle of cavitation
Head.
Background technology
Currently, the exploitation with ocean to ocean, the more tired oceanographic equipment also the more, due to ship, bridge, ocean platform etc.
Long-term bubble of invading causes a large amount of bacterial adhesions in its material table in the marine biological environment of strong corrosive seawater and strong adhesive force
Face forms very thick adhesive layer and schmutzband, has a significant impact to shipping sail speed and equipment life in view of these attachments,
Therefore, the cleaning of oceanographic equipment will be a very huge engineering.
For domestic and international cleaning technique and the analysis of application.Cleaning way has dock cleaning and underwater cleaning at present, including
Spatula technology, sandblast technology turn brush technology, sound field technology, high pressure and ultra-high pressure water fluid jet technology, abrasive water jet Flow Technique, flood
Do not have type cavitating water jet technology；Spatula technical efficiency is low, cleaning is long in time limit, is no longer main wash mode, frequently as nondominant hand
Section occurs.Grit blasting operation is simple, and equipment cost is cheap, but environmental pollution is serious, endangers workers ' health.Turn brush suitable for soft
The cleaning of biology, and to the difficult removal of shelf-like biology.Abrasive water-jet harmony field technology is due to there are technological difficulties, still needing into one
Step research.Cleaning by High Pressure Water Jet is efficient, but safety operation needs professional training, and secondary rust problem is serious.Superelevation is pressed into
Set cleaning equipment can be well solved the recycling for returning rust problem and waste water and dregs.But these cleaning techniques generally can be to the base of ship
Priming coat generates destruction.
Invention content
In order to overcome the shortcomings of above-mentioned cleaning technique, the purpose of the present invention is to provide a kind of sprays of submerged polylinker cavitation
Head, the cavitation nozzle are to utilize cavitation bubble in pulsation and rupture, in a liquid the strong sound such as generation sound miniflow, spray and shock wave
Effect, the impurity on peel sample surface, achievees the purpose that cleaning.
In order to achieve the above object, the technical proposal of the invention is realized in this way：
A kind of submerged polylinker cavitation nozzle, including a water inlet A, three water outlet Bs and be connected to three and go out
Cavitating nozzle on the B of the mouth of a river, the cavitating nozzle include using the sequentially connected spring leaf spout 4 of screw thread, turbulence cavity 1 and leading
Flow chamber 2；Concussion 3 is provided in turbulence cavity 1；It is provided with diversion trench on 2 inner wall of diversion cavity；
The spring leaf spout 4 is horn-like made of flexible material, and edge is broached-tooth design, is arranged in spout central
There is vibrations reed 5 to form narrow slit.
The water inlet A is mutually 120 ° with three water outlet Bs, to offset the axial reaction force with radial direction of water inlet.
The inside of described concussion 3 is hollow, and drives that there are six holes.
Compared with the prior art, the present invention has the following advantages：
(1) it gives cavitation nozzle plus vibrations reed 5, enhances cavitation wave resonance effect.
(2) three nozzle connection of submerged is used, cleaning area is increased；And a part can be offset axially and radially
Reaction force；Erosion effect can be improved under floodage.
(3) the cavitation jet cleaning of low-pressure can guarantee while taking out stains, and does not destroy and is painted by processing surface
Antifouling corrosion-inhibiting coating；Security performance is high, will not cause danger to user, be capable of the safety of effective guarantee operating personnel.

Specific implementation mode
With reference to the accompanying drawings and detailed description, the present invention will be further described：
Referring to Fig.1, Fig. 2, Fig. 3, a kind of submerged polylinker cavitation nozzle, including a water inlet A, three water outlet Bs
And it is connected to the cavitating nozzle in three water outlet Bs, the cavitating nozzle includes using the sequentially connected spring leaf of screw thread
Spout 4, turbulence cavity 1 and diversion cavity 2；Concussion 3 is provided in turbulence cavity 1；It is provided with diversion trench on 2 inner wall of diversion cavity.
Reference Fig. 3, Fig. 4, Fig. 5, the spring leaf spout 4 is horn-like made of flexible material, and edge is sawtooth knot
Structure is provided with vibrations reed 5 in spout central and forms narrow slit.
Referring to Fig.1, Fig. 2, the water inlet A are mutually 120 ° with three water outlet Bs, axial and radial to offset water inlet
Reaction force.
With reference to Fig. 3, the inside of concussion 3 is hollow, and drives that there are six holes, it has restriction effect to fluid, can increase
The flow velocity of fluid reduces pressure, since the effect of barometric gradient is cavitation follicular rupture, when liquid is sprayed from spout, and bar shaped spray
Outwardly extending vibrations reed 5 is provided with before mouthful, spray orifice is divided into two parallel slits by spring leaf, with reference to Fig. 5
The operation principle of the present invention is that：When high-pressure hydraulic pump injects highly pressurised liquid, by water inlet A, from three water outlet Bs
Into in three nozzles, water inlet and three water outlets are mutually 120 °, to offset the axial reaction force with radial direction of water inlet, liquid
When body enters cavitating nozzle Fig. 3, by diversion cavity 2, under the guide functions of diversion trench, turbulent flow is formed, causes the shake of concussion 3
It is dynamic, it can generate a large amount of cavitation bubble in earthquake chamber 1, cavitation bubble enters when having spring leaf spout 4, from after the ejection of narrow slit spout,
Since flow velocity is very fast and fluid viscosity effect, two string vortex will be generated in jet axis both sides, vortex narrow slit both sides in turn
It sends out, direction of rotation is on the contrary, these vortex rotations can lead to the jet stream laterally upper pulsating nature variation pressed, while can also cause spring
The vibrations of piece just will produce strong edge tones, and to the schmutzband of hull, there are one vibrating effects, and the liquid ejected is to target
Body also can be there are one execution, to achieve the purpose that cleaning.When nozzle operation under water, jet stream is sprayed from nozzle at high speeds
Afterwards, generate shear action with surrounding static liquid or low speed circulation, form vortex cavitating water jet, also can intensifier target body surface face it is broken
Bad effect.
The vigorous erosion when present invention highlights cavitating water jet low pressure acts on and will not destroy the technical characterstic of coating, prominent
The advantage and necessity of underwater cleaning.Finally, the powerful dock cleaning characteristics of super-pressure are summarized, it is proposed that flood type
Based on cavitating water jet technology, the development trend for the hull under-water cleaning complete set of equipments that multiple technologies are combined is low to realize
Energy consumption is cleaned without destruction, environmentally protective ship fouling.
