Abstract
The utility model discloses a silencer for a fan of a dust collector. The silencer is arranged between the fan and an exhaust chimney, and comprises a shell of a metal material, wherein one end of the shell is provided with an air inlet; the air inlet is connected with an air inlet flange; the other end of the shell is provided with an air outlet; the air outlet is connected with an air outlet flange; a sound absorption component is arranged in the shell and comprises a sound absorption wall and a sound absorption fence; the sound absorption wall is tightly attached to the inner wall of the shell; the sound absorption fence is arranged in the cavity of the shell; and the sound absorption wall and the wound absorption fence consist of two porous plates and extra-fine glass wool sandwiched between the plates. According to the silencer, the noise produced by the fan can be absorbed by using the superior sound absorption performance of the extra-fine glass wool, so that the aim of reducing the noise is fulfilled.
Description
Technical field
The utility model relates to the dusting apparatus technical field, more particularly, relates in particular to a kind of fan of dust remover baffler.
Background technique
Traditional dusting apparatus system mainly is made of dust shield, dust sucting pipeline, dirt Gas Cooler, deduster, blower fan, air draft chimney etc., blower fan in system directly is connected with the air draft chimney, because fan operation speed is higher, the noise that produces is larger, easily cause noise pollution, affect the workman healthy.
The model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of fan of dust remover baffler is provided, and is arranged between blower fan and air draft chimney the noise that produces when reducing fan operation.
For achieving the above object, fan of dust remover baffler provided by the utility model, the shell that comprises metal material, one end of shell is intake grill, be connected with the intake grill flange on intake grill, the other end of shell is exhaust outlet, be connected with the exhaust outlet flange on exhaust outlet, be provided with the sound-absorbing assembly in shell, described sound-absorbing assembly comprises the sound-absorbing wall be close on outer casing inner wall and is arranged on sound-absorbing fence in cavity pocket of outer cover, and sound-absorbing wall and sound-absorbing fence are by two porous plates and are clipped in that super glass wool between plate is superimposed to be consisted of.
In use, that the utility model is arranged between blower fan and air draft chimney, the exhaust outlet of guaranteeing simultaneously intake grill flange and blower fan is tightly connected, the air intake pipe of exhaust outlet flange and air draft chimney is tightly connected, after the air that is mingled with noise enters baffler, fully contact sound-absorbing wall and sound-absorbing fence in baffler, utilize the good sound absorption qualities of super glass wool to absorb the noise that blower fan produces, thereby reach the purpose of noise reduction.
