Scum removing device of float glass melting furnace

The utility model belongs to the technical field of glass manufacturing, and provides a scum removing device of a float glass melting furnace. The floating slag removing device of the float glass melting furnace is provided with a floating slag runner used for discharging floating slag. The scum runner is arranged on the wall of the melting furnace in front of the neck water bag; the two scum flowchannels are symmetrically arranged left and right; the scum flow channel is communicated with the melting furnace, the width of the scum flow channel is 80200mm, and the depth of the scum flow channel is 50100mm below the molten glass level; a control gate plate is arranged in the scum flow channel; and the outer side of the control flashboard, namely one side, far away from the melting furnace,of the control flashboard is provided with a sealing refractory material which is poured in the dross flow channel and is used for sealing and insulating heat. The quality of molten glass entering the cooling part is improved
