In the seal-reinforced pit furnace cover, the sleeve cover and the outer sleeve are matched through threads to form a seal and fixedly connected.
In the seal-reinforced pit furnace cover, the outer sleeve and the upper cover plate are welded to form a seal and fixedly connected.
In the reinforced and sealed pit furnace cover, the top end of the reinforced suspension rod is in fastening connection with the nut through threaded fit.
In the above-mentioned seal-reinforced pit furnace cover, the filler is heat insulating cotton.
In the well type furnace cover with the reinforced seal, the peripheries of the upper cover plate and the lower cover plate are fixedly connected through welding.
In the well-type furnace cover with the reinforced seal, the web plate is fixedly connected with the lower cover plate through welding.
In the reinforced and sealed pit furnace cover, the bottom end of the reinforced suspender is fixedly connected with the web plate through welding.
In the seal-reinforced pit furnace cover, a hoisting plate is arranged at the top of the upper cover plate, and a hoisting hole is formed in the hoisting plate.
Compared with the prior art, the well type furnace cover with the reinforced seal has the following advantages:
transfer original jib welded seal to dustcoat seal structure to prevent the high temperature environment of seal part direct contact furnace chamber, and then effectively avoid seal part's the desoldering problem, reach the leakproofness requirement of jib installation on the bell, effectively prevent the gas leakage problem at the installation gap, ensure the high efficiency and the security of pit furnace operation.
