Abstract
The utility model discloses a low -noise centrifugal ventilator, it is including the shell, the electric cabinet, the shell top is equipped with the motor, is equipped with the inlet scoop on shell one side, and inlet scoop one side is equipped with elementary block, and elementary block one side is equipped with oil and gas separator, and oil and gas separator one side is equipped with the active carbon filter screen, is equipped with the turbofan in the shell, and shell air outlet department is equipped with blind, and the turbofan is equipped with all around inhales the sound cotton, and the air outlet department of turbofan is equipped with the coiled pipe, the device structural design is reasonable, and the convenience is laid in the installation, through carrying out multilayer trickle and recovery processing to the oil smoke, through inhaling the sound and cotton and carry out buffering process to turbine motor exhaust wind increasing in the turbine studio, guarantees under the normal amount of wind condition of air purification device to reduce the noise that turbine motor produced, improved the treatment effeciency of oil smoke.
Description
Technical field
The utility model is ventilation purifier, is low-noise centrifugal ventilator in particular.
Background technique
Existing kitchen ventilation device adopts porous filter screen, strip filter net mostly, and its major function is that some dust in air and oil smoke are discharged to outside device, in order to reduce wind loss, mostly need the filter screen of larger aperture, will filtering effect be reduced like this, thus in the words that impeller spiral case cleans not in time, the performance of ventilation plant will become very poor, noise increases, and the filter screen adopting aperture little, advantage is that filtering effect improves, but filter screen easily blocks, and noise also can strengthen.
Model utility content
The purpose of this utility model is the shortcoming for purifiers different in background, provides low-noise centrifugal ventilator, under ensureing normal ventilation state, reduces noise by increasing little noise elimination structure.
In order to solve the problem existing for background technique, the utility model is by the following technical solutions: low-noise centrifugal ventilator, it includes shell, electric control box, described housing top end is provided with motor, described shell side is provided with air sucking mouth, described side, air sucking mouth is provided with elementary block, described elementary block side is provided with deaerator, described deaerator side is provided with activated charcoal strainer, turbofan is provided with in described shell, described air outlet of casing place is provided with blind, described turbofan surrounding is provided with acoustical cotton, and the exhaust outlet place of turbofan is provided with coiler.
Described coiler is connected by bayonet socket with between turbofan, and is provided with acoustical cotton equally in coiler.
Be provided with impeller in described turbofan and be provided with acoustical cotton.
Utility model works principle is as follows: when this device is started working, air with dust enters from wind inlet, first after oarse-grained dust tentatively being filtered by elementary block, secondly by inertia deaerator, oil is separated by the air with oil smoke, finally by carbon leaching material, harmful matter in moisture and air is absorbed.Clean by the oil smoke process in which floor filtration treatment suck air, by laying acoustical cotton around the turbo-dynamo of Air exhaust, the noise produced when turbofan rotates can be reduced in a large number, secondly by snakelike, buffered is carried out to the wind that turbofan is discharged, weaken the air quantity that turbofan directly blows venetian blind, and then greatly reduce the noise of ventilation plant.
In sum, the advantage of this model utility is as follows: this apparatus structure is reasonable in design, install and lay conveniently, through carrying out multilayer trickle to oil smoke and recycling, by carrying out buffered to turbine indoor increase acoustical cotton with to the wind of turbo-dynamo discharge, under ensureing the normal air quantity situation of air cleaning unit, thus reduce the noise of turbo-dynamo generation, improve the treatment effeciency of oil smoke.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model.
Wherein, 1, shell; 2, electric control box; 3, motor; 4, air sucking mouth; 5, elementary block; 6, activated charcoal strainer; 7, deaerator; 8, turbofan; 9, blind; 10, acoustical cotton; 11, coiler.
Embodiment
With reference to accompanying drawing 1, low-noise centrifugal ventilator, it includes shell, electric control box, described housing top end is provided with motor, described shell side is provided with air sucking mouth, described side, air sucking mouth is provided with elementary block, described elementary block side is provided with deaerator, described deaerator side is provided with activated charcoal strainer, is provided with turbofan in described shell, and described air outlet of casing place is provided with blind, described turbofan surrounding is provided with acoustical cotton, and the exhaust outlet place of turbofan is provided with coiler.
Described coiler is connected by bayonet socket with between turbofan, and is provided with acoustical cotton equally in coiler.
Be provided with impeller in described turbofan and be provided with acoustical cotton.
When this device is started working, air with dust enters from wind inlet, first after oarse-grained dust tentatively being filtered by elementary block, secondly by inertia deaerator, oil is separated by the air with oil smoke, finally by carbon leaching material, harmful matter in moisture and air is absorbed.Clean by the oil smoke process in which floor filtration treatment suck air, by laying acoustical cotton around the turbo-dynamo of Air exhaust, the noise produced when turbofan rotates can be reduced in a large number, secondly by snakelike, buffered is carried out to the wind that turbofan is discharged, weaken the air quantity that turbofan directly blows venetian blind, and then greatly reduce the noise of ventilation plant.
