The invention provides a water-cooling silencer comprising a first chamber, a second chamber, an admission pipe and an exhaust pipe, wherein a water body is packaged in the first chamber; silencing cotton is covered on the inner wall of the second chamber; the admission pipe penetrates through the first chamber; one end of the admission pipe is introduced to the outside, and the other end passes through the second chamber; one section of the admission pipe, which is positioned in the first chamber, is a curved pipe; and the exhaust pipe is introduced to the outside from the second chamber. The water-cooling silencer has the advantages of good silencing effect and simple structure and is convenient to manufacture.
Description
Affiliated technical field
The present invention relates to a kind of silencer, especially, is a kind of water cooled silencer that is used for various motors.
Background technique
In the engine exhaust process, gas is gone out relief opening fast, because pressure and speed and ambient air differ greatly, will produce huge noise, therefore, generally all needs to install baffler to reduce noise.
Present baffler mainly includes resistive baffler and resistant noise-reducing device, and resistive baffler mainly utilizes quieter material that sound wave is absorbed, thereby reaches erasure effect; The resistant noise-reducing device mainly makes sound wave reflect and interfere in that muffler chamber is indoor, thereby weakens the sound intensity gradually.
In fact, what present most of baffler adopted is the composite structure of above-mentioned two kinds of bafflers, owing to only rely on oneself's interference of noise air-flow and the sound absorption of noise reduction cotton, the energy of noise air-flow slows down comparatively limited, need make up by the chamber of complexity noise is carried out interreflection and absorption, just can reach erasure effect preferably.
Summary of the invention
At the problems referred to above, the object of the present invention is to provide a kind of water cooled silencer, it not only has good erasure effect, and simple in structure, and is easily manufactured.
The technical solution adopted for the present invention to solve the technical problems is: this water cooled silencer comprises first chamber, second chamber, suction tude, outlet pipe;
Be packaged with water body in described first chamber; Described second chamber inner wall is covered with the noise reduction cotton;
Described suction tude runs through described first chamber, and an end leads to the external world, and the other end penetrates in described second chamber, and described suction tude is divided into one section curved tube in described first chamber interior;
Described outlet pipe leads to the external world from described second chamber interior.
As preferably, described first chamber and second chamber are separated by a total chamber by a dividing plate.
As preferably, described first chamber and second chamber be two close to each other cylindric, and described curved tube is a volute.
As preferably, described first chamber and second chamber are two flat brick body shapes that pile up mutually, and described curved tube is reciprocal rugosity.
As preferably, described suction tude is made of copper pipe or aluminum pipe.
As preferably, the outlet of described suction tude is vertical mutually with the import of described outlet pipe.
As preferably, the outlet of described outlet pipe is horn-like.
Beneficial effect of the present invention is: this water cooled silencer is when work, introduce the high temperature noise air-flow that motor is discharged by described suction tude, this high temperature noise air-flow is by described first chamber time, meet rapidly cold step-down, flow into described second chamber, again through the reflection and the absorption of second chamber thereby become low-pressure gas, further weaken loudness of a sound, at last, when air-flow was discharged by described outlet pipe, loudness of a sound was very faint.This baffler not only has good erasure effect, and simple in structure, and is easily manufactured.

Embodiment
The present invention is further described below in conjunction with drawings and Examples:
Embodiment one
In embodiment illustrated in fig. 1 one,
This water cooled silencer comprises the first chamber 1a, the second chamber 1b, suction tude 2, outlet pipe 3;
Be packaged with water body in the described first chamber 1a; The described second chamber 1b inwall is covered with noise reduction cotton (not shown);
The described first chamber 1a and the second chamber 1b longitudinally are separated by a demarcation strip by a total chamber of round barrel shape;
Described suction tude 2 runs through the described first chamber 1a, and an end leads to the external world, and the other end penetrates in described second chamber 3, and described suction tude 2 is divided into one section volute in the described first chamber 1a inside;
The wallboard welding of described suction tude 2 and described first chamber 1a or the described second chamber 1b, and described suction tude 2 is copper pipe or aluminum pipe, has higher thermal conductivity;
Described outlet pipe 3 leads to the external world from the described second chamber 1b inside, and described outlet pipe 3 is one section right-angle elbow pipe, and its import is vertical with the outlet of described suction tude 2, thereby makes the noise air-flow obtain reflection interval as much as possible in the described second chamber 1b.
The outlet of described outlet pipe 3 is a horn mouth, thereby expands gradually when air-flow is discharged, thereby further relaxes the pressure difference of noise air-flow and ambient air.
Embodiment two
Figure 2 shows that second embodiment of the present invention, in this embodiment, this water cooled silencer comprises the first chamber 1a, the second chamber 1b, suction tude 2, outlet pipe 3;
Be packaged with water body in the described first chamber 1a; The described second chamber 1b inwall is covered with noise reduction cotton (not shown);
The described first chamber 1a and the second chamber 1b are separated along thickness direction by a demarcation strip by a rectangular-shaped total chamber, present two flat brick body shapes that pile up mutually,
Described suction tude 2 runs through the described first chamber 1a, and the entrance point 21 of described suction tude 2 leads to the external world in the described first chamber 1a, outlet end 22 penetrates in described second chamber 3, and described suction tude 2 part in the described first chamber 1a is folding shape, and the plan view of described suction tude 2 as shown in Figure 3.
The wallboard welding of described suction tude 2 and described first chamber 1a or the described second chamber 1b, and described suction tude 2 is copper pipe or aluminum pipe, has higher thermal conductivity;
Described outlet pipe 3 leads to the external world from the described second chamber 1b inside, and the import of described outlet pipe 3 is provided with the outlet of described suction tude 2 is vertical, thereby makes the noise air-flow obtain reflection interval as much as possible in the described second chamber 1b;
Described outlet pipe 3 fixedly is welded in the described second chamber 1b by support 4;
The outlet of described outlet pipe 3 is a horn mouth, thereby expands gradually when air-flow is discharged, thereby further relaxes the pressure difference of noise air-flow and ambient air.
The related water cooled silencer of the foregoing description one and embodiment two is when work, introduce the high temperature noise air-flow that motor is discharged by suction tude, this high temperature noise air-flow is by first chamber time, meet rapidly cold step-down, flow into second chamber, again through the reflection and the absorption of second chamber thereby become low-pressure gas, further weaken loudness of a sound, at last, when air-flow was discharged by outlet pipe, loudness of a sound was very faint.This baffler not only has good erasure effect, and simple in structure, and is easily manufactured.
