OVERFLOW TYPE ASPHALT DEWATERING AND HEATING DEVICE

The utility model discloses an overflow type asphalt dewatering and heating device, which is characterized in that a flow path for the high temperature fume is divided into a heating-up heating fume path composed of a flue pipe, a heating-up fume pipe and a discharge flue and an overflow dewatering fume path composed of a main fume pipe, an auxiliary fume pipe, an evaporating box, an evaporating pipe, a fume guide chamber, a ring type fume guide chamber and a fume pipe. An asphalt overflowing and dewatering channel is a vertical fire-pipe boiler type for separating the dewatering process and the heating-up process and combining the dewatering process and the heating-up process into integration. The vertical fire-pipe boiler type has rapid heating-up, big heating area and high thermal inefficiency; the stir is not needed. The utility model has the advantages of energy saving, safe and convenient operation; the overflow and the leakage do not exist; the overflow type asphalt dewatering and heating device is suitable for the dewatering and heating of the engineering asphalt.
