According to the draught fan noise reduction system, the discharged air generated by the draught fans is discharged into the air room, the noise absorption layers are arranged at the positions, opposite to air discharging openings, in the air room, the noise generated by the draught fans is effectively reduced, and impurities in the discharged air are adsorbed to the noise absorption layers; meanwhile, the noise absorption layers are detachable, and convenience is brought to washing and repeated use.
Description
Technical field
The utility model relates to grain processing field, relates in particular to a kind of blower fan noise reduction system.
Background technique
Along with scientific and technological development, in traditional grain storage and processing industry, technological means uses face significantly to improve, and working efficiency promotes greatly, and still, noise and dust that in grain processing, machine produces have certain injury to environment and human health.Paddy course of working generally includes removal of impurities, rice huller paddy, rice husk separation, husk rice, rice refining, classification supervisor, and in this process, one of blower fan is visual plant, and it all plays an important role in the steps such as removal of impurities, rice husk separation, conveying, rice refining, classification.Conventionally, blower fan exhaust port is straight-through outdoor, and its air draft producing is directly discharged into outdoor, but blower fan can produce the noise up to 100dB in the course of the work, and consequent noise and dust endanger seriously environment and staff.Therefore, controlling the noise and the dust pollution that in blower fan working procedure, produce is those skilled in the art assistant officer's problem to be solved.
Model utility content
For solving the technical problem existing in background technique, the utility model proposes a kind of blower fan noise reduction system, its simple in structure, with low cost, long service life, can effectively reduce noise and dust pollution that in grain processing process, blower fan produces.
A kind of blower fan noise reduction system the utility model proposes, the noise producing for reducing blower fan in paddy course of working, it is characterized in that, comprise machine room and wind room, machine room is for accommodating at least one Fans, wind room and machine room are adjacent, on the first side wall between wind room and machine room, have at least one window, at window, place is provided with air exhausting device, the air outlet tube of each blower fan all connects the air exhausting device at a window place and by air exhausting device, the exhaust in blower fan is discharged in wind room, the second sidewall that wind room is relative with described the first side wall is provided with dismountable sound-absorption layer, the air draft direction of air exhausting device is relative with sound-absorption layer, sound-absorption layer is made up of porous sound absorbing material.
Preferably, the 3rd sidewall in wind room is provided with openable door.
Preferably, sound-absorption layer adopts polyester fibre cotton material to make.
In the utility model, the noise that the blower fan noise reduction system proposing produces for reducing blower fan in paddy course of working, it comprises machine room and wind room, blower fan is located in machine room, air draft blower fan being produced by air exhausting device is discharged in wind room, and in wind room, the position relative with air exhausting device is provided with detachable sound-absorption layer.The blower fan noise reduction system arranging in the above described manner, simple in structure, with low cost, the air draft that blower fan is produced is discharged in wind room, by sound-absorption layer being set with exhaust port relative position, effectively reduce blower fan produce noise, and by the adsorbing powder dust in air draft to sound-absorption layer, sound-absorption layer is detachable simultaneously, is convenient to clean and Reusability.
Brief description of the drawings
Fig. 1 is the broken section structural representation of a kind of blower fan noise reduction system that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the broken section structural representation of a kind of blower fan noise reduction system that the utility model proposes.
With reference to Fig. 1, a kind of blower fan noise reduction system the utility model proposes, for reducing blower fan 3 in paddy course of working, this system comprises machine room 1 and wind room 2, in machine room 1, be equipped with the blower fan 3 using in three paddy course of working, wind room 2 is adjacent with machine room 1, the air draft that discharge for accommodating blower fan 3 in wind room 2;
On the first side wall between wind room 2 and machine room 1, have three windows 21, at each window, 21 places are provided with air exhausting device 22, the air outlet tube 11 of each blower fan 1 is connected with an air exhausting device 22 at exhaust outlet place, the second sidewall that wind room 2 is relative with above-mentioned the first side wall is provided with dismountable sound-absorption layer 23, and sound-absorption layer 23 is 25-35kg/m by density
3polyester fibre cotton material make, the 3rd sidewall in wind room 2 is provided with openable door 24.
In specific embodiment, the density of sound-absorption layer 23 is 30kg/m
3, the thickness of sound-absorption layer 23 is 10cm; Ensure noise and adsorbing powder dust best results.
In the working procedure of the blower fan noise reduction system of the present embodiment, the air draft that blower fan 3 produces enters wind room 2 via air outlet tube 31 by air exhausting device 22, air exhausting device 22 makes air draft wind direction towards sound-absorption layer 23, sound-absorption layer 23 can reduce the noise that blower fan 3 produces on the one hand, can adsorb on the other hand dust in air draft, thereby reduce the harm to environment and staff; Staff can enter wind room 2 by door 24, thereby the sound-absorption layer 23 that adheres to dust is pulled down and cleaned or change from the second sidewall, ensures that sound-absorption layer 23 reduces the effect of noise and absorption dust, increases the service life.
In the utility model, the noise that the blower fan noise reduction system proposing produces for reducing blower fan in paddy course of working, it comprises machine room 1 and wind room 2, blower fan 3 is located in machine room 1, air draft blower fan 1 being produced by air exhausting device 22 is discharged in wind room 2, and in wind room 2, the position relative with air exhausting device 22 is provided with detachable sound-absorption layer 23.The blower fan noise reduction system arranging in the above described manner, simple in structure, with low cost, the air draft that blower fan is produced is discharged in wind room 2, by sound-absorption layer 23 being set with the exhaust port relative position of air exhausting device 22, effectively reduce blower fan produce noise, and by the adsorbing powder dust in air draft to sound-absorption layer, sound-absorption layer is detachable simultaneously, is convenient to clean and Reusability.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; be equal to replacement or changed according to the technical solution of the utility model and model utility design thereof, within all should being encompassed in protection domain of the present utility model.
