一种鼓风机扩压锥管消音器 One kind of the cone diffuser blower silencer
技术领域 Technical Field
 本发明涉及鼓风机消音器领域，具体涉及一种结合消音与扩压锥管的鼓风机扩压锥管消音器。  The present invention relates to the field of blower silencers, in particular to a combined muffler and diffuser drogue drogue diffuser blower silencer.
 消音器是一种在允许气流通过的同时，又能有效阻止或减弱声能向外传播的装置，主要用于机械设备的进出口管道或通风管道的噪声控制，在鼓风机中都有使用消音器，然而一般鼓风机中消音器和扩压锥管是相互独立的，因此设备占用空间大，布置不方便。  is a silencer while allowing airflow and can effectively prevent or attenuate acoustic energy propagating outward means, mainly for noise control inlet and outlet piping or ventilation ducts of mechanical equipment, the blower in both the use of silencers, blower silencers however general and diffuser drogue are independent, so the device occupies a large space, convenient arrangement.
 发明目的:为了解决现有技术的不足，本发明将扩压锥管和消音器组合起来，提供了一种技能扩压又能消音的扩压锥管消音器。  The object of the invention: In order to solve the deficiencies of the prior art, the present invention will diffuser cone pipe and muffler combine to provide a skill diffuser diffuser can mute the cone muffler.
 本发明的目的是通过这样的技术方案实现的，一种鼓风机扩压锥管消音器，包括扩压锥管本体，所述扩压锥管本体具有进风口，出风口及外壳，所述进风口截面小于所述出风口截面，所述进风口安装有第一固定筒，所述出风口安装有第二固定筒，所述外壳内部设有孔板，所述孔板与所述外壳之间设有隔板，所述隔板将所述孔板与所述外壳之间的空间分隔成上部和下部，所述上部和下部内设有消音装置。  The object of the present invention is achieved by such technical solutions to achieve A blower tube diffuser cone muffler, including the cone diffuser body, the body having a taper pipe diffuser inlet, outlet and shell, the said inlet section smaller than the cross-sectional outlet, said inlet attached to a first fixed cylinder, the outlet is mounted a second fixed cylinder, is provided inside the housing orifice, the orifice plate and the housing a partition between the separator space between the plate and the housing is partitioned into upper and lower portions, the upper and lower portions are equipped with silencer.
 所述进风口设有第一法兰，所述出风口设有第二法兰。  into the air with a first flange, the outlet provided with a second flange.
 所述孔板面向所述外壳的一侧设有玻璃布。  The side facing the housing plates with a glass cloth.
 所述玻璃布为厚度0.1mm的平纹无碱玻璃布。  The glass thickness of 0.1mm plain cloth E-glass cloth.
 所述消音装置为消音棉或者消音板。  The device is a silencer muffler or silencer cotton board.
