Abstract
The utility model disclose and a kind of good heat-insulation effect is provided, little water cooled silencer takes up room.The utility model comprises inner anechoic chamber (1), exhaust duct and ash-discharge opening (2), and described water cooled silencer also comprises water jacket layer (3), and described water jacket layer (3) is set in periphery, described inner anechoic chamber (1).The utility model can be used for boat diesel engine exhaust field.
Description
Technical field
The utility model relates to a kind of water cooled silencer.
Background technique
Baffler is mounted in the low noise device that falls on aerodynamic force equipment air-flow path or in inlet and exhaust system.As everyone knows, boats and ships are as marine communication means, and its power plant generally adopt diesel engine, and baffler is installed on diesel engine, and the very noisy that the waste gas of discharging when diesel engine can be worked produces absorbs, to eliminate, to reduce the pollution of Noise upon Environment.On the outlet pipe of each main frame/subsidiary engine of modern ships, the heat insulation mode of the general muffler using is all at the coated very thick thermal-protective material in baffler outside, has reached and has reduced the object that heat that baffler distributes heats up to cabin, place.
Tradition can not well completely cut off the impact on place compartment environment temperature of heat that baffler distributes with the coated baffler of thermal-protective material, after main frame long-play, the insulated material temperature of baffler has been baked to and has slowly started to extraneous distribute heat, and the Bao Biaoyin of this type of baffler has been coated thick thermal-protective material, so volume ratio is larger, a lot of valuable spaces in cabin have been taken.
In sum, the baffler of prior art exists that effect of heat insulation is poor, the deficiency such as large takes up room.
Model utility content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art exactly, provides a kind of good heat-insulation effect, little water cooled silencer takes up room.
The technological scheme that the utility model adopts is: the utility model comprises inner anechoic chamber, exhaust duct and ash-discharge opening, and described water cooled silencer also comprises water jacket layer, and it is peripheral that described water jacket layer is set in described inner anechoic chamber.
Described water jacket layer is provided with water intake, water outlet and discharge opening, is also provided with the through hole corresponding with described exhaust duct on described water jacket layer.
Inlet end and the outlet side of described water intake, described water outlet, described discharge opening and described exhaust duct are equipped with flange.
Described exhaust duct comprises exhaust supervisor and is somely looped around described exhaust and is responsible for peripheral exhaust branch pipe, and some described exhaust branch pipe front ends are cylindrical and are provided with bloop group.
Described water jacket layer inside is also provided with baffle plate, and described baffle plate comprises front screen, middle baffle plate and backboard, and the described baffle plate that is positioned at described water jacket layer interlayer is equipped with some weep holes, and baffle plate is provided with the through hole corresponding with exhaust supervisor and exhaust branch pipe.
The beneficial effects of the utility model are: because the utility model comprises inner anechoic chamber, exhaust duct and ash-discharge opening, described water cooled silencer also comprises water jacket layer, and it is peripheral that described water jacket layer is set in described inner anechoic chamber.Described water jacket layer is provided with water intake, water outlet and discharge opening, is also provided with the through hole corresponding with described exhaust duct on described water jacket layer.So the utility model is by add water in described water jacket layer, thereby baffler internal heat is taken away, utilized the heat of the isolated baffler of water layer outwards to distribute simultaneously.
Because described water jacket layer inside is also provided with baffle plate, described baffle plate comprises front screen, middle baffle plate and backboard, and described baffle plate is arranged with some weep holes outward, and baffle plate is provided with exhaust supervisor and exhaust branch pipe and thinks corresponding through hole.So the utility model can, by described baffle plate by water more equal even adding fully in described water jacket layer, improve effect of heat insulation.

Embodiment
As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises inner anechoic chamber 1, in described inner anechoic chamber 1, be provided with the exhaust duct joining with bavin machine oil outlet pipe, described exhaust duct comprises exhaust supervisor 7 and is arranged on four exhaust branch pipes 8 that 7 surroundings are responsible in described exhaust, and described exhaust branch pipe 8 front ends are cylindrical and are provided with bloop group 9.The utility model also comprises two ash-discharge openings 2 that are arranged on bottom, and the water jacket layer 3 that is enclosed within periphery, described inner anechoic chamber.On described water jacket layer 3, below the one end near inlet end, be provided with water intake 4, above the one end near exhaust end, be provided with water outlet 5, below is provided with discharge opening 6.Water flows to from described water intake 4, flows out, distributing of described water jacket layer 3 interior isolated heats from water outlet 5.Described discharge opening 6 is to drain in time ponding after using in low temp area, in order to avoid freeze to causing harmful effect the working life of equipment.
As shown in Figure 4, in described water jacket layer 3, be provided with front screen 10, described front screen 10 is provided with the through hole 14 corresponding with described exhaust supervisor 7 and described exhaust branch pipe 8, and front screen 10 positions that are positioned at described water jacket layer 3 interlayers are provided with some weep holes 13.
As shown in Figure 5, be provided with middle baffle plate 11 in described water jacket layer 3, described middle baffle plate 11 is provided with the through hole 14 corresponding with described exhaust supervisor 7 and described exhaust branch pipe 8, and baffle plate 11 positions that are arranged in described water jacket layer 3 interlayers are provided with some weep holes 13.
As shown in Figure 6, in described water jacket layer 3, be provided with backboard 12, described backboard 12 is provided with the through hole 14 corresponding with described exhaust supervisor 7 and described exhaust branch pipe 8, and backboard 12 positions that are positioned at described water jacket layer 3 interlayers are provided with some weep holes 13.
Inner anechoic chamber 1 of the present utility model is as good as with conventional muffler, by replace original coated thermal-protective material to completely cut off distributing of internal heat with water jacket layer 3.Water intake 4 on described water jacket layer 3 is connected to the drainage pipe of main frame cooling water, cooling water has water outlet 5 to discharge after filling with whole baffler water jacket layer 3, due to constantly flowing of cooling water, the heat in described inner baffler 1 can be taken away, water layer is effectively blocked distributing of internal heat.Meanwhile, discharge opening 6 can drain ponding after use, avoids ponding after low temp area is used to freeze.The thick end of described water jacket layer 3, is thin, effectively reduces equipment volume.
The novel boat diesel engine exhaust field that can be used for of this use.
