Abstract
The utility model relates to the technical field of fans and discloses a noise-elimination integrated pipeline fan which comprises a noise eliminating barrel, a pipeline fan body, a connecting piece, a rubber damping pad, a motor, a flow deflector and an impeller. The pipeline fan body is embedded in the noise eliminating barrel, the rubber damping pad is arranged between the pipeline fan body and the noise eliminating barrel which are fixed through the connecting piece, the motor is arranged in the pipeline fan body, the flow deflector is arranged at the upper end of the motor, and the impeller is arranged at one end of the motor. The noise-elimination integrated pipeline fan is reasonable in structural design, simple to mount and convenient to use; by the damping pad between the pipeline fan body and the noise eliminating barrel, internal vibration of the pipeline fan body is reduced, and mechanical noise of the fan body is lowered; the pipeline fan is integrated, thereby being simple to mount; thickness of a noise eliminating material can be increased qualitatively according to actual noise limit value on site, noise eliminating effect is improved, and client's needs are met.
Description
technical field:
The utility model relates to a kind of one-piece type pipeline fan of eliminating the noise, and belongs to blower fan technical field.
background technique:
Blower fan is important pollution source of noise.Reduce fan noise significant to reducing environmental pollution.Fall low noise approach and have two kinds: the one, take stopgap measures, adopt and eliminate the noise or sound arrester; The 2nd, effect a permanent cure, in design, use aerodynamic noise principle to reduce noise.The former effect is remarkable, and the latter's difficulty is larger, still Changshu not, and the noise reduction reaching has certain limit.
At present, more and more higher to the noise requirements of ventilation in office building, commercial and residential building, hospital, grand theater and testing laboratory, but the pipeline fan of more existing ventilations, its noise objective can not meet usage requirement, ventilation in some buildings higher to noise requirements, more existing pipeline fans cannot use.
model utility content:
For the problems referred to above, the technical problems to be solved in the utility model is to provide a kind of one-piece type pipeline fan of eliminating the noise.
A kind of one-piece type pipeline fan of eliminating the noise of the present utility model, it comprises silencing pot, pipeline fan, connecting sheet, Rubber shock-absorbing pad, motor, guide plate, impeller, pipeline fan is embedded in silencing pot, between pipeline fan and silencing pot, fix by connecting sheet, and be provided with Rubber shock-absorbing pad, in pipeline fan, be provided with motor, the upper end of motor is provided with guide plate, and one end of motor is provided with impeller.
As preferably, the internal layer of described silencing pot adopts sound-absorbing material to make, and sound-absorbing material can use PU foamed cotton, polyurethane, centrifugally glass-wool etc., and the skin employing carbon steel board of silencing pot is made.
As preferably, the length of length L >=twice pipeline fan of described silencing pot.
As preferably, the shell of described pipeline fan and impeller all can adopt galvanized steel plain sheet, cold rolled sheet or plastic material to make.
The beneficial effects of the utility model: its reasonable in design, install simple, easy to use, by the beam between pipeline fan and silencing pot, reduce the internal vibration of pipeline fan, also reduce the mechanical noise of blower fan itself, simultaneously because be one-piece type pipeline fan, so assembling is simple and easy, and can be according to the thickness of the on-the-spot qualitative increase muffler material of actual noise limit value, improve soundproof effect, meet customer need.
brief description of the drawings:
For ease of explanation, the utility model is described in detail by following concrete enforcement and accompanying drawing.
