耐火材料厂成型压砖机一般采用空气风动压把,操作上节省人力,但是噪声较大,压把排气筒噪声达118分贝。为了改善劳动条件,我厂制成一种简易风动压把消声器。 这种消声器是用厚度为2毫米的钢板焊制成80×80 × 500毫米外筒,筒内焊有与筒壁成45°角的挡板,筒体尾部装填旧碎泡沫塑 Refractory factory molding brick press generally use pneumatic wind pressure, the operation to save manpower, but the noise is larger, the pressure of the exhaust pipe noise up to 118 dB. In order to improve working conditions, I plant made a simple pneumatic pressure muffler. This muffler is made of steel with a thickness of 2 mm welded 80 × 80 × 500 mm outer tube, the tube welded to the wall at a 45 ° angle of the baffle, the tail of the cylinder filled with broken foam
