Detailed Description
The technical solution of the present invention will be described in detail below.
When the furnace body 4 normally works, the interior of the furnace body is in a high-temperature state, and a heat preservation strip 9, a first sealing ring graphite packing 7 and a second sealing ring fluororubber ring 8 are respectively arranged from the thermal state to the outside; the heat preservation strip 9 and the first sealing ring graphite packing 7 play isolated thermal effect, and the fluororubber circle 8 compresses tightly the back and plays sealed effect, and sealed backup pad 5 is located graphite packing 7 and the 8 below of fluororubber circle and is regarded as the support this moment.
As a preferred embodiment, the water cooling jacket 1 is positioned on the corresponding fluororubber ring 8 on the furnace cover plate 2, and the aging degree of the fluororubber ring 8 is further relieved by the water cooling effect.
As a preferred embodiment, the furnace cover plate 2 is connected with the furnace body 4 through the bolts 3, when replacing and maintaining, the whole furnace cover plate 2 can be removed only by removing the bolts 3, and the sealing devices around the furnace body 4 below the furnace cover plate 2, namely the heat preservation strip 9, the graphite packing 7 and the fluororubber ring 8, or other accessories such as the sealing support plate 5 can be replaced and maintained at the same time.
As a preferred embodiment, a sealing groove 6 is arranged above the sealing support plate 5 and inside the heat preservation strip 9 and used for fixing the graphite packing 7 and the fluororubber ring 8, so that the problem that the structure of the sealing device is damaged due to displacement when the fluororubber ring 8 is pressed is solved; as preferred embodiment, seal groove 6 is twice seal groove, and graphite packing 7 and fluororubber circle 8 are fixed respectively to twice seal groove, and fixed effect is better.
As a preferred embodiment, in order to ensure the stability of the graphite packing in a high-temperature environment, the graphite packing 7 is a high-temperature graphite packing.
In a preferred embodiment, the insulating strips 9 are made of refractory bricks, glass fiber wool, aluminum silicate fiber wool or ceramic fiber wool in order to ensure the heat insulation effect of the insulating fibers.
