一种防止镀镍的羰基镍粉包装机
摘要：
本实用新型公开了一种防止镀镍的羰基镍粉包装机，属于羰基镍粉生产领域，解决了现有包装机的下料螺旋内部容易形成镀镍层的问题。本实用新型包括储料仓和下料螺旋，下料螺旋连接于储料仓底部，下料螺旋由圆筒壁和螺旋式送料内杆组成，在圆筒壁外围设有冷却夹套，冷却夹套上分别设有进气口和出气口，进气口上连接有进气管道，出气口上连接有出气管道，进气管道和出气管道均与冷却器相连，出气管道上连接有供气管道。本实用新型通过在下料螺旋的圆筒壁外围加装冷却夹套，使得下料螺旋在工作过程中不断被冷却降温，从而防止下料螺旋内部镀镍，达到延长下料螺旋使用寿命、提升产品质量的目的。
摘要（英）：

The utility model discloses a nickel carbonyl powder packaging machine capable of preventing nickel plating, belongs to the field of nickel carbonyl powder production, and solves the problem that a nickel plating layer is easy to form in a blanking screw of an existing packaging machine. The blanking device comprises a storage bin and a blanking screw, the discharging screw is connected to the bottom of the storage bin. The discharging screw is composed of a cylindrical wall and a screw type feeding inner rod, a cooling jacket is arranged on the periphery of the cylindrical wall, an air inletand an air outlet are formed in the cooling jacket, the air inlet is connected with an air inlet pipeline, the air outlet is connected with an air outlet pipeline, the air inlet pipeline and the air outlet pipeline are both connected with the cooler, and the air outlet pipeline is connected with an air supply pipeline. The cooling jacket is additionally arranged on the periphery of the cylindricalwall of the discharging screw, so that the discharging screw is continuously cooled in the working process, nickel plating in the discharging screw is prevented, and the purposes of prolonging the service life of the discharging screw and improving the product quality are achieved.
