Abstract
The utility model relates to a kind of noise-decreasing device of pumped vacuum systems, and it comprises and is arranged on the middle roll-over between vacuum pumping pump relief opening and exhaust chimney, the foamed cotton layer being arranged on middle roll-over suction port and the activated carbon adsorption layer be arranged between foamed cotton layer and middle roll-over air outlet.The design of roll-over during the utility model adopts, by foamed cotton layer and activated carbon adsorption layer, gas is cushioned, reduce the noise that the impact of gas to gas exhaust duct sends, simultaneously foamed cotton layer can moisture in adsorbed gas, activated carbon adsorption layer can purify gas, and making can not atmosphere pollution from the gas of stack emission, in addition, structure of the present utility model is simple, and it is convenient to implement.
Description
Technical field
the utility model relates to a kind of noise-decreasing device of pumped vacuum systems.
Background technique
at present, pumped vacuum systems for vacuumizing is very common, the exhaust end of its vacuum pumping pump adopts conveyance conduit and exhaust chimney directly discharged to air usually, but, in the process of pumping gas, gas easily and pipeline or exhaust chimney collide, and produce noise, especially to the late into the night, make a very bad impression to the people's living environment in surrounding or factory.
Summary of the invention
technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of noise-decreasing device of pumped vacuum systems.
for solving above technical problem, the utility model takes following technological scheme:
a noise-decreasing device for pumped vacuum systems, it comprises and is arranged on the middle roll-over between vacuum pumping pump relief opening and exhaust chimney, the foamed cotton layer being arranged on middle roll-over suction port and the activated carbon adsorption layer be arranged between foamed cotton layer and middle roll-over air outlet.
concrete, foamed cotton layer is sound insulation foam.
specifically implement and preferred aspect according to one of the present utility model, suction port is arranged in the side lower part of roll-over, and air outlet is arranged in the top of roll-over opposite side.
in addition, foamed cotton layer and suction port, all there is gap between activated carbon adsorption layer and air outlet.
due to the enforcement of above technological scheme, the utility model compared with prior art tool has the following advantages:
the design of roll-over during the utility model adopts, by foamed cotton layer and activated carbon adsorption layer, gas is cushioned, reduce the noise that the impact of gas to gas exhaust duct sends, simultaneously foamed cotton layer can moisture in adsorbed gas, activated carbon adsorption layer can purify gas, and making can not atmosphere pollution from the gas of stack emission, in addition, structure of the present utility model is simple, and it is convenient to implement.
Accompanying drawing explanation
below in conjunction with accompanying drawing and specific embodiment, the utility model is described in more detail:
fig. 1 is the structural representation according to noise-decreasing device of the present utility model;
wherein: 1, vacuum pumping pump; 10, relief opening;
2, exhaust chimney;
3, middle roll-over; 30, suction port; 31, air outlet;
4, foamed cotton layer (sound insulation foam);
5, activated carbon adsorption layer.
Embodiment
as shown in Figure 1, the noise-decreasing device of the pumped vacuum systems of the present embodiment, it comprises and is arranged on the middle roll-over 3 between vacuum pumping pump 1 relief opening 10 and exhaust chimney 2, the foamed cotton layer 4 being arranged on middle roll-over 3 suction port 30 and the activated carbon adsorption layer 5 be arranged between foamed cotton layer 4 and middle roll-over 3 air outlet 31.
concrete, in this example, foamed cotton layer 4 is sound insulation foam.And then noise-decreasing, simultaneously can also moisture in adsorbed gas.
but in order to reach good noise reduction effect, in this example, suction port 30 is arranged in the side lower part of roll-over 3, and air outlet 31 is arranged in the top of roll-over 3 opposite side.And then change the flow direction of gas.
in addition, foamed cotton layer 4 and suction port 30, all there is gap between activated carbon adsorption layer 5 and air outlet 31, be convenient to entering from the suction port 30 of middle roll-over 3 of gas open, air outlet 31 is discharged.
the specific implementation process of the present embodiment is as follows:
the relief opening 10 of gas self-evacuating vacuum pump 1 is extracted out, and enter in middle roll-over 3 by conveyance conduit from suction port 30, gas directly impacts on sound insulation foam, simultaneously by moisture in the adsorbed gas of sound insulation foam, then through the absorption of activated carbon adsorption layer 5, purified gas is delivered to exhaust chimney 2 from air outlet 31 by conveyance conduit.
the technique scheme that the present embodiment adopts has following advantage:
1), by foamed cotton layer and activated carbon adsorption layer gas is cushioned, reduce the noise that the impact of gas to gas exhaust duct sends;
2), can moisture in adsorbed gas by foamed cotton layer;
3), by activated carbon adsorption layer can purify gas, making can not atmosphere pollution from the gas of stack emission.
above the utility model is described in detail; its object is to allow the personage being familiar with this art can understand content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to Spirit Essence of the present utility model change or modify, and all should be encompassed in protection domain of the present utility model.
