Fig. 2 is the partial enlargement schematic diagram of A in Fig. 1;
Fig. 3 is the perforated pipe schematic diagram of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
This kind of noise absorption unit of dust collector of the present utility model as shown in Figures 1 to 3, it comprises inlet pipe 1, sound attenuation 2 and escape pipe 3. Inlet pipe 1 connects the vapor pipe of suction cleaner, tail gas imports step-down in sound attenuation 2, falls and make an uproar, and tail gas is derived by escape pipe 3. Described inlet pipe 1 is inserted on described sound attenuation 2, described inlet pipe 1 is provided with joint flange 11 and air inlet port 12, inlet pipe 1 is fixedly connected with sound attenuation 2, joint flange 11 is for connecting the vapor pipe of suction cleaner, simplifying connection structure, the region being provided with air inlet port 12 is positioned at sound attenuation 2 inside. Expansion chambers 21 and resonant chamber 22 it is provided with in described sound attenuation 2, it is preferable to, the volume of expansion chambers 21 is greater than the volume of resonant chamber 22. Being provided with an insulating board 23 between described expansion chambers 21 and resonant chamber 22, this insulating board can so that acoustic wave energy reflects. Being evenly distributed with ventilating pit 230 on described insulating board 23, tail gas can be imported resonant chamber 22 by ventilating pit 230 from expansion chambers 21. Described sound attenuation 2 inwall is pasted with the cotton layer 24 of a noise reduction, and the thickness of the cotton layer 24 of noise reduction is 10 ~ 20mm, is close to sound attenuation 2 inwall, and the cotton layer 24 of noise reduction can absorb acoustic wave energy, reduces noise. Be provided with air filter 31, first dividing plate 32, second partition 33 in described escape pipe 3 successively and filter the cotton layer 34 of noise reduction, air filter 31 can dust in cleaning of off-gas, filter the cotton layer 34 of noise reduction and can absorb acoustic wave energy, and can not stop that air-flow passes through. It is provided with silencing cavity 35, first dividing plate 32, second partition 33 and escape pipe 3 between described first dividing plate 32 and second partition 33 and forms a silencing cavity 35, it is possible to play the effect of sound-deadening and noise-reducing.
