HZQ 20型混凝土搅拌站是上海华东建筑机械厂研制的新产品。该站由涡桨式搅拌机、悬臂拉铲、垂直导轨提升料斗、水泥筒仑、螺旋输送机、称量系统、供水系统、附加剂供应系统、气控及电控系统组成,见图1。它适用于中等规模以上的建筑施工、桥梁工程和混凝土预制品厂。该站装拆方便、可迅速拆解,以大组件的形式装运。其搅拌主机为涡桨式搅拌机,特别适用于搅拌干硬性混凝土,并具有搅拌均匀,生产率高等优点。该站经过近二年的 HZQ 20 concrete mixing plant is a new product developed by Shanghai East China Construction Machinery Factory. The station consists of a turboprop mixer, a cantilever pull shovel, a vertical rail lifting hopper, a cement cylinder, a screw conveyor, a weighing system, a water supply system, an additive supply system, an air control and an electronic control system, as shown in FIG. It is suitable for medium-scale construction, bridge engineering and concrete prefabrication plants. The station is easy to assemble and disassemble, can be dismantled quickly, and shipped in the form of large components. The mixing host is a turboprop type mixer, which is particularly suitable for mixing dry hard concrete, and has the advantages of uniform stirring and high productivity.
