Abstract
The utility model discloses a noise reduction biomass boiler. The noise reduction biomass boiler comprises a fan set and a hearth which is connected with the fan set. The fan set is installed inside an acoustic shield. An air inlet and an air outlet are of a horn shape. Silencers are arranged on both the air inlet and the air outlet. A hose is arranged at the joint of the fan set and a pipeline. A shock pad is arranged at the joint of the fan set and the ground. A sound absorption device is laid on a shell of the hearth. Sound absorption screens are arranged on the two sides of the shell of the hearth. The fan set is arranged inside the acoustic shield, sound attenuation processing is conducted on the air let and the air outlet of the fan set, and therefore noise pollution is reduced. The sound absorption device is arranged on the shell of the hearth, the sound absorption screens are arranged on the two sides of the shell, and therefore the noise insulation effect is achieved.
Description
Technical field
The utility model relates to biomass boiler, is specifically related to a kind of noise reduction biomass boiler.
Background technique
Biomass boiler can produce great noise in running, and noise has serious impact to the healthy of operator, so must be controlled the noise of boiler.The noise of biomass boiler mainly the wind comes from air power noise of unit and the mechanical noise that also has casing, tube wall, bearing of motor.In existing biomass boiler running, noise is large, and defening effect is poor.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The model utility content
The purpose of this utility model is to provide a kind of impact of noise on operator that can reduce to move, and reduces the biomass boiler of noise.
For reaching above-mentioned purpose, the technological scheme that the utility model adopts is: a kind of noise reduction biomass boiler is provided, comprises blower fan group and the burner hearth be connected with the blower fan group; Described blower fan group is arranged on acoustic hood inside, and the suction port of blower fan group and air outlet flare, be equipped with silencing apparatus, and the joint of blower fan group and pipeline is provided with flexible pipe, with the joint on ground, is provided with beam; The shell of described burner hearth is equipped with sound absorber, and both sides are provided with absorbing screen.
Preferably, acoustic hood comprises cover plate, and covers damping layer and absorbent treatment on cover plate.
Preferably, damping layer is soft rubber.
Preferably, sound absorber comprises the Clad Steel silk screen, filling porous sound-absorbing material between the Clad Steel silk screen.
Preferably, silencing apparatus is circular pipe, and inwall scribbles sound-absorbing material.
In sum, the utlity model has following advantage: 1, the blower fan group is arranged on acoustic hood inside, and the suction port of blower fan group and air outlet have been carried out to the noise reduction processing, has reduced noise pollution; 2, furnace enclosure is provided with sound absorber, and both sides are provided with absorbing screen, reaches every the effect of making an uproar.
The accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
The schematic diagram that Fig. 2 is acoustic hood;
The schematic diagram that Fig. 3 is the blower fan group.
Wherein, 1, blower fan group; 2, acoustic hood; 3, air outlet; 4, silencing apparatus; 5, pipeline; 6, beam; 7, flexible pipe; 8, burner hearth; 9, sound absorber; 10, absorbing screen; 11, cover plate; 12, damping layer; 13, absorbent treatment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
The utility model provides a kind of noise reduction biomass boiler, as shown in Figure 1 to Figure 3, comprises blower fan group 1 and the burner hearth 8 be connected with blower fan group 1; Blower fan group 1 supplies its biomass burning by air intake burner hearth 8.Blower fan group 1 is arranged on acoustic hood 2 inside, and the suction port of blower fan group 1 and air outlet 3 flares, be equipped with silencing apparatus 4.Pass into burner hearth 8 by air outlet 3 after the suction port suction of ambient air by blower fan group 1.Horn shape all is arranged in suction port and air outlet 3, by moment the wind speed of correcting one's mistakes make its reducing noise, and be equipped with silencing apparatus 4, can reach good de-noising effect.
Blower fan group 1 is connected with the suction port of burner hearth 8 by pipeline 5, in the joint with pipeline 5, is provided with flexible pipe 7, can weaken the noise of air stream air-out unit 1.Blower fan group 1 can produce vibration in running, with ground, touches and can produce larger noise.Blower fan group 1 of the present utility model is provided with beam 6 with the joint on ground, can alleviate these mechanical vibration, reduces noise.Shell at burner hearth 8 is equipped with sound absorber 9, and both sides are provided with absorbing screen 10, makes the noise of burner hearth 8 inside be difficult for being passed to the external world, or weakens the resonance between noise.
Further, acoustic hood 2 comprises cover plate 11, and covers damping layer 12 and absorbent treatment 13 on cover plate 11, and damping layer 12 is soft rubber.
Further, sound absorber 9 comprises the Clad Steel silk screen, filling porous sound-absorbing material between the Clad Steel silk screen.
Further, silencing apparatus 4 is circular pipe, and inwall scribbles sound-absorbing material.
Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
