Abstract
The utility model discloses an acoustic hood, which comprises an acoustic hood body. The acoustic hood consists of a lateral acoustic board and a top acoustic board. An air inlet muffler is arranged at one end of the acoustic hood body, and an air outlet muffler is arranged at the other end of the acoustic hood body. An axial flow fan is arranged between the air inlet muffler and the air outlet muffler. A fan acoustic absorption piece is arranged on the axial flow fan. An acoustic door and an acoustic window are reserved in the lateral acoustic board. The acoustic hood has the advantages that: all noise sources are accommodated in the acoustic hood, and both the air inlet muffler and the air outlet muffler are arranged outside the acoustic hood, so that the problem about overall radiation ventilation is solved, the acoustic hood is highly energy-saving and good in soundproof effect, and a high sound insulation factor is ensured.
Description
Technical field
The utility model relates to a kind of acoustic hood.
Background technique
At present, the protection of people's pay attention to day by day environment for industrial pollution and improvement civilian and other association area noise pollution such as oxygen compressor, air compressors, has dropped into great amount of manpower and material resources and financial resources.But still have drawback: the main components and parts of sound insulation adopt simple insulation board thereby defening effect bad, can not well meet customer need; Heat dissipation ventilation places in the cover with axial-flow blower, because case temperature is too high, has influenced the proper functioning of axial-flow blower, thereby has reduced the effect of heat dissipation ventilation, and it is also bigger to consume energy.Therefore, need provide a kind of new technological scheme to solve the problems referred to above.
The model utility content
The purpose of the utility model provides the good acoustic hood of a kind of soundproof effect.
The technological scheme that the utility model adopts is:
A kind of acoustic hood; Comprise the acoustic hood body, said acoustic hood body is made up of side acoustic board and end face acoustic board, and said acoustic hood body one end is provided with the air intake silencing apparatus; The said acoustic hood body the other end is provided with the air-out silencing apparatus; Between said air intake silencing apparatus and the air-out silencing apparatus axial-flow blower is housed, the blower fan sound absorption plate is housed on the said axial-flow blower, offer soundproof door and sound proof window on the acoustic board of said side.
Said blower fan sound absorption plate comprises that two perforated plates that laterally arrange, two perforated plate inboards are fitted with glass cloth, are equipped with packing between two glass cloth.
Said packing adopts superfine glass face sound-absorbing material.
The beneficial effect of the utility model: noise source all is coated in the acoustic hood, and air intake silencing apparatus and air-out silencing apparatus all are arranged on outside the acoustic hood, have solved the integral heat sink ventilating problem, and good energy saving property guarantees that noise insulation factor is big, and soundproof effect is good.
