1.存在问题某用户从我中交西安筑路机械有限公司购置了1台沥青混凝土搅拌设备,又从其他公司购置了絮状添加剂投料机,用以在拌制改性沥青混凝土过程中,向沥青混凝土搅拌设备的搅拌机内添加木质纤维素。在生产过程中,因该投料机投料风泵风量过大,经常将搅拌机与称料斗之间用于密封的软连接吹开,导致木质纤维素及粉尘飘散,并造成称量斗称重不准,出现“飘称”现象,严重影响沥青混凝土生产。用户只得暂时停用投料机。
1. Existing Problems Some users purchased one asphalt concrete mixing equipment from Xi’an Jiaotong Road Machinery Co., Ltd. and purchased the floc additive hopper from other companies. During the process of mixing modified asphalt concrete, Add lignocellulose to the mixer in the asphalt mixing plant. In the production process, due to the feeding machine wind pump air volume is too large, often between the mixer and said the hopper between the soft seal for blowing open, resulting in the release of lignocellulosic and dust, and caused the weighing bucket is not allowed to weigh , Appear “floating name ” phenomenon, seriously affecting the asphalt concrete production. The user has to temporarily disable the feeder.
