Separating chamber and the second separating chamber, the 4th separating chamber, the 6th separating chamber；
The hot gas of the annealing furnace discharge connects by regulation valve plate with the first separating chamber air inlet, first separating chamber
Air outlet is connected by heat energy pipe with the second separating chamber air inlet, and the second separating chamber air outlet is divided by heat energy Guan Yu tri-
Air compartment air inlet is connected, and the 3rd separating chamber air outlet is connected by the separating chamber air inlets of heat energy Guan Yu tetra-, and the described 4th
Separating chamber air outlet by the separating chamber air inlets of heat energy Guan Yu five connect, the 5th separating chamber air outlet by heat energy pipe with
6th separating chamber air inlet connects；The 6th separating chamber air outlet is arranged mouth and is in communication with the outside by exporting blower fan and waste gas.
Further, the outlet blower fan is high temperature draught fan.
Annealing furnace remnants hot gas is delivered to drying oven using the waste heat and regulation valve plate of annealing furnace in the utility model, and
By some heat energy pipes in the first separating chamber, the second separating chamber, the 3rd separating chamber, the 4th separating chamber, the 5th separating chamber and the 6th
Circulated between separating chamber in " S " type, while improving and drying in-furnace temperature humidity in drying oven can be avoided excessive, can be achieved
The abundant drying of ductile iron pipe.
Compared with prior art, the utility model has the advantages that production efficiency is high, cost is low, easily promotes.
Brief description of the drawings
