Description
Technical field
The present invention relates to de-watering apparatus field peculiar to vessel, more particularly to a kind of pneumatic injection de-watering apparatus peculiar to vessel.
Background technology
In Ship Building and Repairing and retrofit process, when be commonly encountered rainy weather, on ship or segmentation on all can be more or less
Product rain, field worker is removed water in operation in narrow space, influenceed by equipment or pipeline, and large-scale water removal instrument cannot make
With, manually can only bit by bit be cleared up with spade and bucket, operating efficiency greatly reduces, delay effective working, not only
Cost of labor is increased, it could even be possible to schedule delays, to solve this phenomenon, by independent research, using the existing money of shipyard
Source, produces convenient operation, and the tool part for effectively draining the water away " a kind of pneumatic injection de-watering apparatus peculiar to vessel ", is that field worker is carried
Supplier just, reduces time cost, improves operating efficiency.
The content of the invention
Can effectively be drained the water away it is an object of the invention to provide one kind, reduce time cost, improve the ship of operating efficiency
With pneumatic injection de-watering apparatus.
The technical scheme that is used to achieve the above object of the present invention is：A kind of pneumatic injection de-watering apparatus peculiar to vessel, including
Water sucking mouth, vacuum drainage region, air inlet pipe, nozzle, discharge outlet and compressed air inlet, the water sucking mouth and discharge outlet connect respectively
Be connected on the two ends in vacuum drainage region, the air inlet pipe is connected with vacuum drainage region, the nozzle be arranged on air inlet pipe with it is true
The connection end in empty drainage region, the compressed air inlet is arranged on the inlet end of air inlet pipe.
The water sucking mouth and discharge outlet are respectively adopted external screw thread and are connected with vacuum drainage region.
The water sucking mouth and discharge outlet use wedge structure.
A kind of pneumatic injection de-watering apparatus peculiar to vessel of the invention, it is adaptable to which in Ship Building and Repairing and retrofit process, absorption excludes ship
Upper ponding, through overtesting, this pneumatic injection de-watering apparatus can complete draining 20L in 210 seconds, and its operating efficiency is artificial
Three times, considerably reduce cost of labor.

Specific embodiment
As shown in Figures 1 to 8, pneumatic injection de-watering apparatus peculiar to vessel, including water sucking mouth 1, vacuum drainage region 2, air inlet pipe
6th, nozzle 3, discharge outlet 4 and compressed air inlet 5, water sucking mouth 1 and discharge outlet 4 are respectively adopted external screw thread and are connected to vacuum drainage area
The two ends in domain 2, air inlet pipe 6 is connected with vacuum drainage region 2, and nozzle 3 is arranged on the connection of air inlet pipe 6 and vacuum drainage region 2
End, compressed air inlet 5 is arranged on the inlet end of air inlet pipe 6, and water sucking mouth 1 and discharge outlet 4 use wedge structure, when using,
First " snap joint " of compressed air source is connected with the compressed air inlet 5 of this de-watering apparatus, then by soft suction hose and
Scupper hose is connected with water sucking mouth 1 and discharge outlet 4 respectively, opens compressed air valve, and soft suction hose is aligned into water accumulation part on ship,
Remove water function is capable of achieving, ponding is rejected to designated area, it is of the invention after further investigation theoretical foundation " Venturi effect ",
With reference to this feature of shipyard itself compressed air aboundresources, determine that the drive form of this de-watering apparatus, for pneumatic injecting type, drives
Dynamic source is then the compressed air of shipyard, is connected with this de-watering apparatus by snap joint, when the compressed air jet of high speed passes through
During the nozzle of device, negative pressure can be produced at the back side of nozzle, this negative pressure will be rejected to designated area by ponding on adsorbing boat, and this is just
It is the operation principle of pneumatic injection de-watering apparatus peculiar to vessel, in order to reduce cost of manufacture, and it is enough true to ensure that this de-watering apparatus has
Empty drainage region, and meet the principle for making and being simple and convenient to operate, the main body of this de-watering apparatus selects shipyard standard steel pipe,
By repetition test research, seek the equalization point of weight of equipment and soaking effect, the final length for determining main body vacuum drainage region
Degree, its two ends suction side that car has internal thread, this de-watering apparatus respectively is connected using external screw thread with vacuum drainage region, and
Make wedgewise form to be connected with soft suction hose, complete water suction, the discharge ends of this de-watering apparatus are designed to famous " Laval "
Jet pipe form, i.e. de Laval noz(zle), in reducing pipe region, compressed air mixes with drainage water, fluid-mixing pressure head gradually reduce with
The flow velocity of fluid-mixing is improved, in increaser region, the flow velocity of fluid-mixing has reduced, and changes into the pressure head of fluid, improved
The potential energy of fluid, is connected by wedged interface with scupper hose, and water is discharged into designated area.
