Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment 1, as Fig. 1,2, shown in 5, the present embodiment discloses a kind of variable capacity bench vehicle type electrical resistance furnace, comprises body of heater 1, is useful on the burner hearth 2 that holds chassis in body of heater 1, its improvements are: one end of described chassis 6 arranges rear fire door 3, on described body of heater 1, away from one end of rear fire door 3, front fire door 4 and front fire door elevating mechanism 5 are set; Wherein, between fire door 3 and inboard wall of burner hearth, have gap, several push rods 9 are set on rear fire door, sealing block 8 is all installed on the top of each push rod 7, starts the rear available sealing block 8 of push rod 9 gap is sealed.
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 uniformly distributed along the gap between rear fire door and inboard wall of burner hearth.
In the present embodiment, described push rod is controlled the sequencing that starts/close by PLC.
In the present embodiment, described sealing block 8 is fibrous encapsulation piece.
In the present embodiment, described rear fire door adopts inverted T shape steelframe, lays and weld steel plate on steelframe, guarantees to have enough strength and stiffness, and handling are reliable.Go along with sb. to guard him at steel plate edge cylinder iron part, has both prevented rear fire door temperature distortion, has protected again fibrous encapsulation piece.
