Background technology
Ship when navigation in ice region especially in the winter time, floating ice in the seawater can stop up the suction barrier of sea water tank, can influence when serious sea water tank to important system such as fire-fighting, cooling, ballast to the external dynamic sea delivery volume, all stipulate in the particulars of ship that various countries classification society formulates: at the sea water tank heating pipe that necessary supporting thawing is iced except the pressurized air blowpipe is set of ice ship.Generally all adopt steam heating pipe, this is necessary, but in the continuous navigation stage, the discharge cooling water expansion tank of main frame (seawater or river) temperature is about about 45 ℃, continuing like this poured sea water tank, and can effectively to prevent to suck barrier ice stifled, if the pressurized air that is not less than 0.3MPa with pressure pours the sea water tank better effects if simultaneously.Reduce the use amount of the steam of oil burning boiler generation, just reduce oil consumption to a certain extent, energy-conservation meaning is arranged.Especially for do not establish oil burning boiler, more be necessary at this devices of employing such as the medium and small towboat of slight navigation in ice region, auxiliary vessels.
The utility model content
At the problems referred to above, main purpose of the present utility model is to provide a kind of marine main engine that utilizes to discharge the stifled device of the anti-stagnant ice of cooling water heat sea water tank, compare with the device that common anti-stagnant ice is stifled, the stifled device of the anti-stagnant ice that the utility model provides utilizes main frame to discharge the cooling water expansion tank heat and pressurized air impulse force combined action elimination sea water tank ice is stifled, has the meaning of certain ship energy saving.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of marine main engine that utilizes is discharged the stifled device of the anti-stagnant ice of cooling water heat sea water tank, described device comprises: sea water tank, suck grid plate, described suction grid plate is positioned at a side of sea water tank, it is characterized in that: described device also comprises at least one solid drawn pipe, at least one fork-shaped mixing tube, screw down nonreturn valve, one of described solid drawn pipe is connected with screw down nonreturn valve, the other end is a flare tube, the other end of screw down nonreturn valve is the fork-shaped mixing tube, described fork-shaped mixing tube includes the main frame of public termination and discharges cooling water expansion tank arm and compressed air tube, and described sea water tank connects the seawater house steward by sea valve.
Wherein, the angular range of described solid drawn pipe and flare tube is 120 °～150 °.
Wherein, the angle of described solid drawn pipe and flare tube is 135 °.
Wherein, the angular range of described main frame discharge cooling water expansion tank arm and compressed air tube infall is 30 °～60 °.
Wherein, the angle of described main frame discharge cooling water expansion tank arm and compressed air tube infall is 45 °.
Working process of the present utility model is as follows: the seawater that may comprise floating ice enters sea water tank through sucking grid plate, because the liquid that flow out flare tube the inside is that discharge cooling water expansion tank (seawater or the river) temperature of main frame is about about 45 ℃, continuing like this poured sea water tank, and can effectively to prevent to suck grid plate ice stifled, pour the meeting of sea water tank effect better from the fork-shaped mixing tube simultaneously if be not less than the pressurized air of 0.3MPa with pressure, do not have the seawater of ice to enter the seawater house steward, can utilize seawater in the cabin, to do utilizations such as cooling water expansion tank like this through sea valve.
Positive progressive effect of the present utility model is: the stifled device of boats and ships sea water tank ice that prevents that the utility model provides has the following advantages: the utility model utilizes the discharge cooling water temperature of main frame about about 45 ℃, such water continues to pour sea water tank, and can effectively to prevent to suck barrier ice stifled, can pour the sea water tank better effects if with the pressurized air that pressure is not less than 0.3MPa simultaneously.The utility model reduces the use amount of the steam of oil burning boiler generation, just reduces oil consumption to a certain extent, and energy-conservation meaning is arranged.Especially for do not establish oil burning boiler, more be necessary at this devices of employing such as the medium and small towboat of slight navigation in ice region, auxiliary vessels.
