Quantitative discharger of glass kiln

The utility model relates to a quantitative discharger of a glass kiln. The utility model belongs to the field of glass melt. The utility model mainly comprises a material discharging pipe body which is arranged on the kiln. The utility model is characterized in that the position of the material discharging pipe body is changed into the pool bottom from the pool wall; the material discharging pipe body is an alundum pipe, wherein the outer wall of the alundum pipe is wound with an electrical heating wire; the inner and the outer pipe walls of the alundum pipe are coated with platinum layers; sealing refractory clay materials are arranged outside the pipe; the upper layer of the periphery of the sealing refractory clay materials is provided with refractory bricks, the middle layer is provided with sealing bricks, the lower layer is provided with insulating bricks and a feeder line of the heating wire is led out from the insulating bricks. The quantitative discharger well solves the defects that the material discharge of the traditional discharger is not thorough, the traditional discharger has no function on glass metal at the lowest layer of the pool bottom and the controllability of the flow speed of the material discharge is poor. The utility model has big function on decreasing the glass defects, such as stripes, pits, knots, calculus, etc., in glass products.
