Sweeper fan silencer
The invention discloses a sweeper fan silencer. The sweeper fan silencer comprises a silencer shell and an inner wall perforated plate connected into the silencer shell, and the space between the inner wall perforated plate and the silencer shell is filled with a first sound absorption material; one end outside the silencer shell is connected with a silencer inlet, the other end of the silencer shell is connected with a silencer outlet, and the silencer inlet and the silencer outlet both penetrate through the silencer shell; an expansion cavity is formed between inner wall perforated plates inthe silencer shell, a flow guide sound absorption cone is connected into the expansion cavity, and the expansion cavity is divided into a first flow channel and a second flow channel through the flowguide sound absorption cone; and airflow enters the expansion cavity from the inlet of the silencer and flows to the outlet of the silencer from the first flow channel and the second flow channel after being shunted by the diversion sound absorption cone. Air flow of the silencing device enters the expansion cavity after being absorbed by the first sound absorption material, the flow guide soundabsorption cone further absorbs the air flow subjected to primary sound absorption, and the good sound absorption effect of the silencing device is guaranteed through the combined action of the flow guide sound absorption cone and the expansion cavity.
本发明公开了一种清扫车风机消音装置，包括消声器外壳和连接在消声器外壳内的内壁穿孔板，内壁穿孔板和消声器外壳之间填充有第一吸声材料；消声器外壳外的一端连接有消声器入口，另一端连接有消声器出口，消声器入口和消声器出口均贯通消声器外壳；消声器外壳内的内壁穿孔板之间形成膨胀腔，膨胀腔内连接有导流吸声锥体，导流吸声锥体将膨胀腔分隔为第一流道和第二流道；气流从消声器入口进入膨胀腔，经导流吸声锥体分流后从第一流道和第二流道流至消声器出口；本发明的消音装置气流先经过第一吸声材料吸声后进入膨胀腔，导流吸声锥体对初步吸声的气流进一步吸声，两者共同作用保证了本装置具有良好的吸声效果。
