Specific embodiment
The present invention will be further described with reference to the accompanying drawings and detailed description.
As Figure 1-3, the cast insulation of the cast insulation stove with Tooth-locked Quick Closure door structure disclosed by the invention
Stove, including body of heater 11, door structure include the fire door 6 located at fire door, and fire door 6 is provided with handle 7, is around provided with gear ring 5, fire door
Fire door swing arm 4 is provided with, fire door swing arm 4 is hinged or is pivotally connected with arm shaft 2, i.e. fire door swing arm 4 can rotate around arm shaft 2, swing arm
Axle is fixed on fire door support 1, and fire door band tooth flange 9 is provided with fire door, and the fire door band tooth flange 9 has and the phase of gear ring 5
Mutually the tooth of engagement, can realize the locking/release of flange 9 and fire door by rotation, and the driving flange 9 of gear ring rotation driving 3 revolves it
Turn, fire door heat-insulation layer 8 is filled between fire door and flange 9, the inner side of flange 9 is provided with latch segment 10, realizes the positioning of flange rotary.
Cast insulation stove disclosed by the invention when in use, metal is injected from fire door to holding furnace first with liquid-adding device
Liquid, after finishing, makes fire door swing arm 4 be rotated along arm shaft 2 using handle 7, drives fire door 6 to enter fire door band tooth flange 9, then profit
The fire door band tooth flange 9 is driven to rotate it with gear ring rotation driving 3, flange 9 is encountered and stop the rotation after latch segment 10 and lock, this
Tooth on Shi Falan is intermeshed with the gear ring 5 on fire door, realizes the closing of door structure, after being pressurizeed to holding furnace,
Air pressure presses to fire door 6, fire door 6 is tightly pushed down flange 9, furthermore achieved that sealing, can now be cast.Using terminating
Heater exhaust release is incubated afterwards, and the driving fire door band tooth of gear ring rotation driving afterwards 3 flange 9 rotates it, makes tooth and stove on flange
