Abstract
The utility model discloses a vertical type muffler that air -blower was used, including hush pipe, air -supply line and play tuber pipe, the hush pipe is cylindricly, and the shutoff is connected to the equal circular arc of upper and lower port of its hush pipe, is equipped with cotton layer of amortization and otter board layer on the inner wall of hush pipe in proper order, has offered the through -hole in the lower extreme of hush pipe, fixes being provided with the mount pad on the lateral wall of hush pipe, and the symmetry is installed the air -supply line and is gone out the tuber pipe on the lateral wall of hush pipe, be equipped with into pipe flange and one section return bend on the air -supply line, be equipped with out the pipe flange on the play tuber pipe. The utility model discloses a muffler, because the air -blower combustion gas, in the air -supply line got into the hush pipe, after effluent air got into the hush pipe inner chamber in its air -supply line, the back of making an uproar fell in channel qi volume expansion decompression amortization and acoustical coating, and the air current in the hush pipe uses the air -supply line to be restrainted by the air current and surround for central downstream, the air -supply line in the hush pipe, and the noise that produces the air -supply line forms shielding effect, has consequently further reduced the noise again.
Description
Technical field
The utility model relates to a kind of silencer, relates to a kind of vertical type baffler of blower specifically.
Background technique
Baffler is a kind of while permission air-flow passes through, can effectively stop or weaken again the device that acoustic energy is outwards propagated, be mainly used in the import and export pipeline of machinery or the Noise measarement of ventilation duct, use baffler is had in blower, front horizontal baffler is a kind of conventional denoising device, its structure is: a cavity wall arranges Cylindrical object one end connection intake grill of sound absorbing material, and one end connects exhaust outlet.Although this baffler has certain erasure effect, and sound-deadening and noise-reducing effect is undesirable.Want the target of the sound-deadening and noise-reducing of realizing ideal, its technological means has multiple available.But current technological means is obviously to increase gas-flow resistance for cost, and that is, current sound-deadening and noise-reducing is to sacrifice blower performance for cost.
Model utility content
For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of vertical type baffler of blower, and not only erasure effect is obvious for this baffler, gas-flow resistance is little, and discharges foreign matter also easily fast.
To achieve these goals, the technical solution adopted in the utility model is: a kind of vertical type baffler of blower, comprise hush pipe, air intake pipe and air outlet tube, described hush pipe is cylindric, the equal circular sliding slopes shutoff of upper and lower port of its hush pipe, the inwall of hush pipe is provided with silencing cotton layer and web plate layer successively, silencing cotton layer is between hush pipe inwall and web plate layer, tapped through hole is offered in the lower end of hush pipe, the externally threaded plug of configure band on through hole, the sidewall of hush pipe is fixedly installed fitting seat, the sidewall of hush pipe is symmetrically installed with air intake pipe and air outlet tube, the pipeline of air intake pipe and air outlet tube and the intracavity inter-connection of hush pipe, described air intake pipe is provided with inlet pipe flange and one section of bend pipe, and its inlet pipe flange is positioned at outside hush pipe, and its bend pipe is positioned at hush pipe, and the mouth of pipe of bend pipe is positioned at immediately below hush pipe upper end, described air outlet tube is provided with out pipe flange, and the intake grill of its air outlet tube is positioned on hush pipe madial wall.
Preferably, the internal diameter of described air intake pipe does not beat the internal diameter in air outlet tube.
Further, described fitting seat is also provided with mounting hole.
Further, also stiffening rib is provided with between described fitting seat and hush pipe.
Adopt the model utility of the technical program, its beneficial effect is: baffler of the present utility model, due to the gas that blower is discharged, enter in hush pipe through air intake pipe, after in its air intake pipe, effluent air enters hush pipe inner chamber, after gas expansion decompression noise reduction and quieter material noise reduction, air-flow in hush pipe moves downward centered by air intake pipe, air intake pipe in hush pipe is surrounded by air flow stream, forms shielding action, therefore reduce further noise again to the noise that air intake pipe produces; Because the lower end at hush pipe is provided with through hole, and configure plug on through hole, therefore the discharge of foreign matter also facilitates.Not only erasure effect is obvious for baffler of the present utility model, gas-flow resistance is little, and discharges foreign matter also easily fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Number in the figure: 1, hush pipe; 2, air intake pipe; 3, air outlet tube; 4, plug; 5, fitting seat; 11, silencing cotton layer; 12, web plate layer; 13, through hole; 21, inlet pipe flange; 31, pipe flange is gone out; 51, mounting hole; 52, stiffening rib.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, baffler of the present utility model, comprise hush pipe 1, air intake pipe 2 and air outlet tube 3, described hush pipe 1 is in cylindric, the equal circular sliding slopes shutoff of upper and lower port of its hush pipe 1, the inwall of hush pipe 1 is provided with silencing cotton layer 11 and web plate layer 12 successively, silencing cotton layer 11 is between hush pipe 1 inwall and web plate layer 12, tapped through hole 13 is offered in the lower end of hush pipe 1, the externally threaded plug 4 of configure band on through hole 13, the sidewall of hush pipe 1 is fixedly installed fitting seat 5, the sidewall of hush pipe 1 is symmetrically installed with air intake pipe 2 and air outlet tube 3, the pipeline of air intake pipe 2 and air outlet tube 3 and the intracavity inter-connection of hush pipe 1, described air intake pipe 2 is provided with inlet pipe flange 21 and one section of bend pipe, and its inlet pipe flange 21 is positioned at outside hush pipe 1, and its bend pipe is positioned at hush pipe 1, and the mouth of pipe of bend pipe is positioned at immediately below hush pipe 1 upper end, described air outlet tube 3 is provided with out pipe flange 31, and the intake grill of its air outlet tube 3 is positioned on hush pipe 1 madial wall.The internal diameter of described air intake pipe 2 is not more than the internal diameter of air outlet tube 3.Described fitting seat 5 is also provided with mounting hole 51.Stiffening rib 52 is also provided with between described fitting seat 5 and hush pipe 1.
