Abstract

The utility model relates to a thermal insulating and sound muffling device for a flue, in particular to a thermal insulating and sound muffling device for a flue of a vessel engine. The technical scheme is as follows: the thermal insulating and sound muffling device mainly comprises a smoke inlet tube, a mufeler inner tube, a mufeler outer tube and a smoke venting tube, wherein a sealed vacuum tube is formed by the mufeler inner tube and the mufeler outer tube, one end of the vacuum tube is connected with the smoke inlet tube, and the other end thereof is connected with the smoke venting tube, and the joints of the vacuum tube with the smoke inlet tube as well as the vacuum tube with the smoke venting tube are designed to be shaped like flared opening. The thermal insulating and sound muffling device has the benefits of being good in sound-proofing and thermal insulating effects, effectively lowering the noise in a cabin, and alleviating the damage on a human body.

Description

The heat insulation silencer of engine of boat and ship flue

One, technical field:

The utility model relates to the heat insulation silencer of a kind of flue, the heat insulation silencer of particularly a kind of engine of boat and ship flue.

Two, background technique:

At the big ship of navigation in the sea, motor generally all is a diesel engine, and all be in cabin, ventilation condition is poor, at present, the smoke-ejecting pipe that motor is used is simple one deck tube wall, sound insulation, effect of heat insulation are all bad, and diesel engine power is big, and the noise that sends, heat are also big, the heat that motor sent, noise etc. all can be diffused in the cabin, when boats and ships navigate by water for a long time, cause the noise in the cabin very big, temperature is very high, the crewman lives in the cabin, and of long duration will to influence the crewman healthy.

Three, summary of the invention:

The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of heat insulation silencer of engine of boat and ship flue of practicality is provided.

Its technological scheme is: mainly be made up of pipe, baffler outer tube, smoke-ejecting pipe in smoke-intake pipe, the baffler, pipe is formed the vacuum tube that seals with the baffler outer tube in the baffler, and an end of vacuum tube connects smoke-intake pipe, and the other end connects smoke-ejecting pipe.

The beneficial effects of the utility model are: its fabricating cost is lower, designs hommization more, by adopting the isolation of vacuum tube, reduce heat, noise diffusion belowdecks, reach good sound-insulating and heat-insulating effect, effectively reduce noise and heat in the cabin, thereby alleviated harm human body.

Four, description of drawings:

Accompanying drawing 1 is a structural representation of the present utility model;

Among the last figure: pipe 2, baffler outer tube 3, smoke-ejecting pipe 4 in smoke-intake pipe 1, the baffler.

Five, embodiment:

In conjunction with the accompanying drawings 1, the utility model will be further described:

The utility model mainly by manage 2 in smoke-intake pipe 1, the baffler, baffler outer tube 3, smoke-ejecting pipe 4 form, pipe 2 is formed the vacuum tube that seals with baffler outer tube 3 in the baffler, make the heat-insulating sound-insulating better effects if, one end of vacuum tube connects smoke-intake pipe 1, the other end connects smoke-ejecting pipe 4, bell-mouthed shape is made in vacuum tube and smoke-intake pipe 1 and smoke-ejecting pipe 4 joints, makes the intermediate projections of vacuum tube to help the elimination to noise more.

During use, this device is connected to the venting gas appliance of motor, this device is by adopting the isolation of vacuum tube, reduce heat, noise diffusion belowdecks, reach good sound-insulating and heat-insulating effect, effectively reduce noise and heat in the cabin, thereby alleviated harm human body.

Claims

1. heat insulation silencer of engine of boat and ship flue, it is characterized in that: mainly form by pipe (2), baffler outer tube (3), smoke-ejecting pipe (4) in smoke-intake pipe (1), the baffler, pipe (2) is formed the vacuum tube that seals with baffler outer tube (3) in the baffler, one end of vacuum tube connects smoke-intake pipe (1), and the other end connects smoke-ejecting pipe (4).
