Technical field
The present invention relates to a kind of noise abatement device, more particularly to a kind of denoising device for industrial fan.
Background technology
Noise abatement is that existing industry environmental protection to be implemented, and the noise of industrial blower fan is particularly evident, and noise
Source is mainly：Air inlet, fan body, motor and air outlet；Existing administering method is that blower fan and motor are done into sound absorption
Cover, setting ventilation muffler into and out of air port, but, this method brings another negative effect again, causes motor scattered
Heat is not smooth, causes electrical fault or even burns, and in order to solve this problem, prior art is on blower fan, the sound absorption room of motor
Along with forced ventilation muffler is used to radiate（As shown in Figure 1）.So a set of equipment gets off, and the cost of noise abatement improves
A lot, and maintenance personal be particularly summer enter soundproof room in repair when, indoor temperature is up to 60 degree, causes maintenance personal
Cannot stay inside for a long time, and high temperature also influences service life of equipment, the disadvantages mentioned above existed for prior art, it is necessary to
One kind can reduce environment protection treating cost, and effective noise reduction can ensure that sound insulation indoor temperature again, it is ensured that the denoising device of equipment life.
The content of the invention
In order to solve the deficiencies in the prior art, it is an object of the invention to provide one kind can reduce environment protection treating into
This, effective noise reduction can ensure that sound insulation indoor temperature again, it is ensured that the denoising device for industrial fan of equipment life.
To reach above-mentioned purpose, the technology used in the present invention means are：A kind of denoising device for industrial fan,
Sound absorption room is done outside blower fan and motor, air inlet is set against motor non-output end position in sound absorption room, set on air inlet
Suction silencer is put, motor output end connecting fan, air inlet is arranged in sound absorption room, fan outlet passes through air-out
Pipe is connected to outside sound absorption room, and air-out muffler is set on discharge pipe.
Further, the discharge pipe is arranged on sound absorption ceiling plate, and passes sound absorption room, outside sound absorption room
Air-out muffler is set on discharge pipe.
Further, the air inlet is located at blower fan bottom.
Further, the sound absorption room is provided with maintenance door or maintenance door and observation window.
The beneficial effects of the invention are as follows：Structure design is simple, and blast pipe is arranged on into the non-output end of motor, thus can profit
The power produced with motor and blower fan work forms negative pressure, and natural inspiration extraneous air, air inlet is arranged on blower fan bottom,
Allow entrance cold wind by after motor body, form air-flow, then by air inlet, directly take away heat, whole device does not have
There is the forced air inlet radiating motor for setting in the prior art, reduce multiple blast pipes and discharge pipe and be arranged on blast pipe
With the muffler on discharge pipe, manufacturing cost is reduced, and is effectively guaranteed the absorption isolation to motor, fan noise, indoor
Temperature can be also maintained within 30 degree in summer, greatly reduce the temperature in sound absorption room, it is ensured that equipment life and dimension
Repair the working environment of personnel.
Brief description of the drawings
The invention will be further elaborated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of prior art；
Fig. 2 is structural representation of the invention.
In figure：1st, sound absorption room, 2, blast pipe, 3, suction silencer, 4, motor, 5, blower fan, 6, air inlet, 7, go out
Air port, 8, discharge pipe, 9, air-out muffler, 10, radiating blast pipe.
Specific embodiment
Embodiment 1
As shown in figure 1, the structure for using in the prior art, sound absorption room 1 connects near the side of blower fan 5 setting blast pipe 2, blast pipe 2
Air inlet 6 is connect, suction silencer 3 is installed on blast pipe 2, air-out muffler 9 is installed on discharge pipe 8, in motor side
Radiating blast pipe 10 is installed, suction silencer is set on radiating blast pipe 10, set at the top of sound absorption room 1 and force air draft
Pipe, installing cooling fan carries out pressure air draft, and sets muffler on exhaust duct is forced.It can be seen that, in the prior art, structure is auxiliary
Help, equipment investment is big, it is necessary to force blower fan, power consumption is high, and temperature in sound absorption room summer be always held at 60 degree it is left
The right side, is unfavorable for equipment operation and safeguards, reduces equipment life.
As shown in Fig. 2 a kind of denoising device for industrial fan, sound absorption room 1 is done outside blower fan 5 and motor 4, inhaling
Sound booth 1 sets air inlet against the non-output end position of motor 4, and suction silencer 3, the output end of motor 4 are set on air inlet
Connecting fan 5, air inlet 6 is arranged in sound absorption room 1, and air outlet 7 is connected to outside sound absorption room 1 by discharge pipe 8, and
Air-out muffler 9 is set on discharge pipe 8.
The discharge pipe 8 is arranged on the top board of sound absorption room 1, and passes sound absorption room 1, the air-out outside sound absorption room 1
Air-out muffler 9 is set on pipe 8.
The air inlet 6 is located at the bottom of blower fan 5.
The sound absorption room 1 is provided with maintenance door or maintenance door and observation window.
Structure design of the present invention is simple, and blast pipe is arranged on into the non-output end of motor, can thus utilize motor and blower fan
The power for producing that works forms negative pressure, and natural inspiration extraneous air, air inlet is arranged on blower fan bottom, allows the cold wind of entrance
By after motor body, forming air-flow, then by air inlet, directly heat is taken away, whole device is without prior art
The forced air inlet radiating motor of middle setting, reduces multiple blast pipes and discharge pipe and is arranged on blast pipe and discharge pipe
Muffler, manufacturing cost reduction, and the absorption isolation to motor, fan noise is effectively guaranteed, indoor temperature is in summer
Can guarantee that within 30 degree, greatly reduce the temperature in sound absorption room, it is ensured that the work of equipment life and maintenance personal
Environment.
