Deslagging box of medium-speed coal mill

A slag discharging box of a medium-speed coal mill relates to the technical field of material milling devices and comprises a coal mill, the coal mill is connected with a slag falling box, the slag falling box is connected with the left side of the slag discharging box, the slag discharging box is trapezoidal, a slag discharging door is installed on the right side of the slag discharging box, the top of the slag discharging box is fixedly welded with one end of an exhaust pipe, and the other end of the exhaust pipe is fixedly connected with a boiler slag well. And an exhaust valve is mounted on the exhaust pipe. According to the utility model, a semi-closed deslagging box is transformed into a fully-closed deslagging box, and internally-leaked waste gas is led away through the exhaust pipe by utilizing the negative pressure of the boiler, so that the replacement cost is reduced, and the operating environment is improved. 一种中速磨煤机排渣箱，涉及物料碾磨装置技术领域，包括磨煤机，磨煤机与落渣箱连接，落渣箱与排渣箱的左侧连接，排渣箱呈梯形，排渣箱的右侧安装有排渣门，排渣箱的顶部与排气管的一端固定焊
