Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Embodiment 1, such as Fig. 1,2, shown in 5, present embodiment discloses a kind of variable capacity bench vehicle type electrical resistance furnace, including body of heater 1, in body of heater 1, have the burner hearth 2 for accommodating chassis, it thes improvement is that: one end of described chassis 6 arranges rear fire door 3, and on described body of heater 1, the one end away from rear fire door 3 arranges front fire door 4 and front fire door elevating mechanism 5；There is gap between fire door 3 and inboard wall of burner hearth after wherein, rear fire door arranges several push rod 9, the top of each push rod 7 is respectively mounted sealing block 8, and after starting push rod 9, gap is sealed by available sealing block 8.
In the present embodiment, described burner hearth is door opening shape at the cross sectional shape of vertical direction.
In the present embodiment, the gap between described rear fire door and inboard wall of burner hearth is about 70mm.
In the present embodiment, described push rod is driven by electronic connecting rod.
In the present embodiment, the quantity of described push rod 9 is 5, and described 5 push rods are distributed along the gap uniformity between rear fire door and inboard wall of burner hearth.
In the present embodiment, described push rod is controlled the sequencing of on/off by PLC.
In the present embodiment, described sealing block 8 is fibrous encapsulation block.
In the present embodiment, described rear fire door uses inverted T shape steelframe, steelframe is laid and welds steel plate, it is ensured that has enough strength and stiffness, and loads and unloads reliable.Steel plate edge cylinder iron part is gone along with sb. to guard him, and has both prevented rear fire door temperature distortion, has protected again fibrous encapsulation block.
