Description
Technical field
The present invention relates to zigzag silencing apparatus.
Background technology
Blower fan is gas compression and gas conveying machinery, and the mechanical energy of rotation is converted to gas pressure energy during fan operation
Transferred out with kinetic energy and by gas.Architectural, blower fan is widely used in ventilation and heat exchange, and the normal operation of blower fan is related to
The transmission ＆ distribution energy consumption of system, is building energy conservation very crucial part.Due to the rotation of motor and stirring for air during fan operation
It is dynamic, very big noise can be produced, the noise produced when normally being run according to one diameter 800mm of measuring and calculating blower fan is up to 80dB
More than, and architectural generally many Fans link uses, this just further increases noise.At present, for fan noise
Reduction measure, also has the defects such as complicated, inconvenient for use, DeGrain, non-dismountable cleaning, to environmental protection
Pose a big pressure.
The content of the invention
For above-mentioned the deficiencies in the prior art part, the problem of present invention is solved is：A kind of structure for blower fan is provided
Simply, the zigzag silencing apparatus and its processing method and installation method of disassembling cleaning.
To solve the above problems, the technical scheme that the present invention takes is as follows：
A kind of zigzag silencing apparatus, including fixed cylinder, locating ring, noise elimination cotton；Described fixed cylinder both ends open, inside
Provided with noise elimination cavity；Described fixed cylinder includes the semi-circular ring that two sections are in semi-circular structure；Two described semi-circular rings
Dock cylindrical structure；It is provided with the inside of the two ends of two described semi-circular rings and is mutually matched internal thread；Described locating ring is set
Have and external screw thread is provided with the outside of two, locating ring；Described locating ring is arranged on the two of semi-circular ring by external screw thread and internal thread
End；Described noise elimination cotton is arranged in noise elimination cavity；Described noise elimination cotton indention structure；The two ends of described noise elimination cotton are abutted
In the inner side of fixed cylinder two ends locating ring.
Further, the tapered structure of the sawtooth of described noise elimination cotton.
Further, described fixed cylinder is made up of aluminum alloy materials.
Further, it is provided with moving block in the middle of described locating ring；It is fixed that described moving block is fixed on by multiple connecting rods
In the middle of the ring of position.
Beneficial effects of the present invention
The noise elimination cotton that the present invention is designed is zigzag structure, and multilayer can be achieved and eliminates the noise, soundproof effect is more preferable；The saw that the present invention is designed
Tooth form silencing apparatus is flexibly connected by two semi-circular rings and two locating rings and formed, and whole mechanism is unique novel, install and
Dismounting is all very convenient, and disassembly, cleaning can be carried out after prolonged, prevent dust from blocking.

End is connected to the inner side of the two ends locating ring 3 of fixed cylinder 1.The wind of blower fan enters from the opening side of noise elimination cotton 2.Further, it is
Save material, the tapered structure of sawtooth of described noise elimination cotton 2.Further preferably, it is enhancing radiating effect, described fixed circle
Post 1 is made up of aluminum alloy materials.As shown in Fig. 2 further preferably, for ease of people's rotational positioning ring 3, in described locating ring 3
Between be provided with moving block 32.Described moving block 32 is fixed on the centre of locating ring 3 by multiple connecting rods 31.
The zigzag silencing apparatus that the present invention is designed be flexibly connected by two semi-circular rings 13 and two locating rings 3 and
Into whole mechanism is unique novel, and installation and removal are all very convenient, and disassembly, cleaning can be carried out after prolonged, ash is prevented
Dirt is blocked；The noise elimination cotton 2 that the present invention is designed is zigzag structure, and multilayer can be achieved and eliminates the noise, soundproof effect is more preferable, by so tying
The noise elimination cotton 2 of structure, which to install, very to be facilitated, as long as noise elimination cotton 2 is put into fixed cylinder.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God is with principle, and any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
