Draining suction pump peculiar to vessel
Technical field
The present invention relates to a kind of wind-driven water pump, the draining suction pump that especially a kind of suitable shipbuilding industry is used.
Background technique
It is reported that national accomplished shipbuilding was more than 4,000 ten thousand tons in 2010.Safety problem during the boats and ships draining is the most important thing problem that influences the shipbuilding industry development always.Just there is certain potential safety hazard in shipbuilding industry as using the electric pump operation.Nowadays, shipbuilding industry all has the air compressor machine room, and compressed air gas source can be provided; But machine room is from the work surface distance, and the air supply pipe bore is little, and institute's shipbuilding tonnage is big; Hatch is high to the hold height, and this just requires draining to have lift height, flow is big, air consumption is little, weight is light characteristics with pump.Inventor of the present invention is that the patent documentation of CN101545471B discloses a kind of pneumatic sump pump at the Chinese patent notification number of first to file; It can carry out safe draining in the cabin of boats and ships; But long-pending thing of shallow table property and ponding in the hold that can not exhaust need carry out that spoon is ladled out, the barreled water lift with manual work, and rag is rubbed with the hands and done the operation such as grade; Working strength of workers is big, and efficient is low.
Summary of the invention
The object of the present invention is to provide a kind of draining belowdecks, can the exhaust draining suction pump peculiar to vessel of the long-pending thing of shallow table property and ponding in the cabin again.
The technological scheme that realizes above-mentioned purpose is: a kind of draining suction pump peculiar to vessel, comprise pneumatic sump pump, and said pneumatic sump pump comprises housing; Housing is provided with water intake, water outlet, suction port and air outlet, and said air outlet is communicated with liquid jetting device, and said liquid jetting device comprises nozzle and injection pipe; Injection pipe has inlet pipe and mixing tube; Nozzle is plugged in the inlet pipe, and mixing tube is led in the outlet of nozzle, is communicated with suction sleeve on the inlet pipe of the outlet rear side that is positioned at nozzle of said liquid jetting device.
Said air outlet is equipped with outlet pipe, through outlet pipe the air outlet is communicated with the nozzle of liquid jetting device.
Also be connected with diffusing tube behind the mixing tube of said liquid jetting device.
Also be connected with soft suction hose on the said suction sleeve, soft suction hose is communicated with suction sleeve.
Said water outlet is equipped with waste pipe, and the internal diameter of waste pipe progressively enlarges along the water outlet direction.
After adopting the structure of technique scheme, during use, pneumatic sump pump discharges the ponding in the boats and ships cabin through the suction of the water intake on the housing, water outlet draining; When getting rid of the residual water of shallow water, the high speed noise air-flow of pneumatic sump pump gets into liquid jetting device, utilizes the ejector capacity of jet; Near the liquid jetting device nozzle, form low pressure area, through suction sleeve remaining shoaling layer in the cabin is aspirated, the water that is drunk up forms gas, liquid two phase fluid-mixings in the mixing tube of liquid jetting device; Discharge cabin, reach that no raffinate retains in the cabin, cancelled spoonful ladling out in the construction operation in the past, barreled water lift; Rag is rubbed with the hands to do and is waited operation, has alleviated working strength of workers greatly; Owing to have diffusing tube, when suction, not only the flow velocity of the fluid-mixing in the mixing tube of liquid jetting device reduces, and has reduced the noise when absorbing water.The present invention can reach the effect of " clean engineering ", " clean sound engineering ".
Description of drawings
Fig. 1 is the structural representation of draining suction pump peculiar to vessel of the present invention.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing does further detailed explanation to the present invention.
As shown in Figure 1, for draining suction pump peculiar to vessel of the present invention, comprise pneumatic sump pump 1; Said pneumatic sump pump 1 comprises housing 1-1; Housing 1-1 is provided with water intake 4, water outlet 5, suction port 7 and air outlet 9, and said air outlet 9 is communicated with liquid jetting device 2, and said liquid jetting device 2 comprises nozzle 2-2 and injection pipe 2-1; Injection pipe 2-1 has inlet pipe 2-1-1 and mixing tube 2-1-2; Nozzle 2-2 is plugged in the inlet pipe 2-1-1, and the outlet 2-2-1 of nozzle 2-2 leads to mixing tube 2-1-2, is communicated with suction sleeve 3 on the inlet pipe 2-1-1 of the outlet 2-2-1 rear side that is positioned at nozzle 2-2 of said liquid jetting device 2.
As shown in Figure 1; Have cylinder 19, a plurality of blade 21, rotor 23, impeller 25 and main shaft 27 in the housing 1-1 of pneumatic sump pump 1; Impeller 25 passes through main shaft 27 coaxial settings with rotor 23, and said cylinder 19 is fixedly connected with housing 1-1, and blade 21 is movably arranged on the rotor 23; Suction port 7 leads to cylinder 19, and cylinder 19 leads to air outlet 9.It is the disclosed pneumatic sump pump structure of document of CN101545471B that pneumatic sump pump among the present invention can adopt the Chinese patent notification number, also can adopt the structure of other pneumatic sump pump, for example, and gear type pneumatic pump, turbo type pneumatic pump etc.
As shown in Figure 1, for the ease of assembling, said air outlet 9 is equipped with outlet pipe 13, through outlet pipe 13 air outlet 9 is communicated with the nozzle 2-2 of liquid jetting device 2.
As shown in Figure 1, in order to reduce the jet velocity of fluid-mixing in the mixing tube, reduce noise, also be connected with diffusing tube 2-1-3 behind the mixing tube 2-1-2 of said liquid jetting device 2.Owing to having diffusing tube 2-1-3, when suction, not only the flow velocity of the fluid-mixing in the mixing tube 2-1-2 reduces, and reduces the noise when absorbing water.
As shown in Figure 1, for the ease of shallow water or the residual water of suction, and needn't carry pneumatic sump pump 1 to this place away from the cabin somewhere of pneumatic sump pump 1, also be connected with soft suction hose 12 on the said suction sleeve 3, soft suction hose 12 is communicated with suction sleeve 3.Like this, just, very laborsaving as long as move soft suction hose 12 to this place's suction.
As shown in Figure 1, in order to reduce the drainage rate of waste pipe, further noise reduction, said water outlet 5 is equipped with waste pipe 11, and the internal diameter of waste pipe 11 progressively enlarges along the water outlet direction.
When the present invention used, as shown in Figure 1, during use, pneumatic sump pump 1 discharged the ponding in the cabin through 3 suctions of the water intake on the housing 1-1, water outlet 5 drainings; During the residual water of shallow water in getting rid of cabin, the high speed noise air-flow of pneumatic sump pump 1 gets into liquid jetting device 2, utilizes the ejector capacity of jet; Near the nozzle 2-2 of liquid jetting device 2, form low pressure area; Aspirate through remaining shoaling layer in 3 pairs of cabins of suction sleeve, the water that is drunk up forms gas, liquid two phase fluid-mixings in the mixing tube 2-1-2 of liquid jetting device 2, and the kinetic energy of fluid-mixing is converted into the pressure ability in diffusing tube 2-1-3 subsequently; Reduce noise; Discharge cabin then, reach the interior no raffinate of cabin and retain, can reach the effect of " clean engineering ", " clean sound engineering ".
