Specific embodiment
In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model
There is any restriction effect.
As shown in Figure 1-Figure 3, the specific structure of the utility model are as follows: it includes furnace body and fire door, is provided with furnace on furnace body
Body flange 10 is provided with fire door flange 8 on fire door, it further includes retainer 2 and cylinder 3, and U-lag, furnace body method are provided in retainer 2
The interior bottom of the U-lag is arranged in orchid 10, extends multiple equally distributed detent projections 5, tooth on the lateral wall of fire door flange 8
The interior upper end of the U-lag is arranged in 5 matching of shape protrusion；On retainer 2 and be located at U-lag upper end be evenly distributed with it is multiple with
Air cylinder support 1 is fixedly installed on sidewall of the furnace body, retainer is fixedly installed on the side wall of retainer 2 for the opening 7 that detent projection 5 matches
Bracket 4, the fixing end of cylinder 3 are hinged on air cylinder support 1, and the extension end of cylinder 3 and retainer bracket 4 are hinged.
Preferably, the bottom of retainer 2 is contacted with the idler wheel in the second roll wheel assembly 12, and the second roll wheel assembly 12 is fixed on furnace
On the side wall of body.
Preferably, U-lag inner sidewall is contacted with the idler wheel of the first roll wheel assembly 11 in retainer 2, and the first roll wheel assembly 11 is solid
It is scheduled on the side wall of furnace body flange 10.
