Operation under warm environment, labor intensity is low, the vertical annealing device of the high ductile iron pipe of safety coefficient and the method for annealing of equipment.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention are as follows: a kind of ductile iron pipe is set with vertical annealing
It is standby, including melt pit, burner is evenly equipped in melt pit, melt pit is rectangular melt pit, and melt pit top is provided with rotating platform, rotating platform
For the rectangular platform of corresponding melt pit opening, rotating platform lower section middle part is provided with rotary shaft, and rotary shaft two sides are provided with rotation branch
, it is provided with cast tube positioning bracket on rotating platform, is provided with cast tube end fixed plate, rotating platform at the upper side of rotating platform
Cast tube end fixed plate side is provided with telescoping mechanism, telescoping mechanism is connected with cast tube end fixed plate.
The burner is flat-flame burner.
The cast tube end fixed plate is mutually perpendicular to rotating platform.
The rotating platform, cast tube positioning bracket, cast tube end fixed plate, telescoping mechanism material are refractory material.
A kind of vertical annealing device of ductile iron pipe, method for annealing includes the following steps:
1), ductile iron pipe is hoisted on rotating platform, bracket is positioned by cast tube and is positioned；
2), rotating platform rotates, and ductile iron pipe is become vertical state from horizontality, it is solid that cast tube one end is fixed on cast tube end
On fixed board；
3), telescoping mechanism works, and cast tube is displaced downwardly to melt pit bottom, carries out annealing operation；
4) after the completion of, annealing, cast tube is moved up, rotates to horizontality, be transported through by rope mechanism work.
Compared with the prior art, the invention has the following beneficial effects: by the combination of setting melt pit and rotating platform, it will
Ductile iron pipe to be annealed, which erects, to be come, and is transported in melt pit, is carried out annealing operation, easy to use, occupied area is small, is not required to very important person
Member's contact hot environment, labor intensity is low, not will cause scald.
Detailed description of the invention
Following further describes the present invention with reference to the drawings.
Fig. 1 is the structural diagram of the present invention.
