Description
Technical field
The present invention relates to a kind of high temperature furnace door, particularly relate to a kind of high temperature furnace door with expansion joint.
Background technology
General high-temperature heater all has fire door and oven door sealing structure thereof, as shown in Figure 1, sealing device 13 is provided with between fire door 2 and furnace wall 11, obviously, the side corresponding with the fire door rectangular aperture 12 on body of heater 10 inside sealing device 13 when high-temperature heater works is in the condition of high temperature, and outside sealing device 13 is room temperature state, namely fire door 2 with sealing device 13 for boundary, there is the very large temperature difference in fire door 2 medial and lateral, the position that fire door 2 contacts with sealing device 13 is then temperature difference transition zone.Fire door case material adopts metal material to be common selection, and the fire door housing of metal material certainly leads to buckling deformation under inside and outside temperature difference condition, and the larger buckling deformation of the temperature difference is larger, and obviously significantly buckling deformation must cause sealing device 13 to lose efficacy.Therefore, fire door is effectively prevented to lose efficacy due to temperature distortion most important.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art, provide a kind of door structure with expansion joint, with the technical problem effectively preventing fire door from making oven door sealing lose efficacy because of temperature deformation.
Consider the problems referred to above of prior art, according to an aspect disclosed by the invention, the present invention by the following technical solutions:
There is the high-temperature furnace door at expansion joint, comprising:
Housing, the high temperature side of described housing is set to hollow, and the plane surrounding vertical and horizontal compartment of terrain of this hollow part is provided with expansion joint, and extends to the facade near middle perpendicular with high temperature side;
Liner, is arranged on the inner surface at the expansion joint place of described housing;
Inner cover plate, covers on the hollow part of described high temperature side, and is closed this hollow part.
In order to realize the present invention better, further technical scheme is:
According to one embodiment of the invention, in the hollow part of the high temperature side of described housing, be provided with high temperature insulating material.
According to one embodiment of the invention, described housing low temperature side is also set to hollow, and this hollow part is provided with outer cover plate.
According to one embodiment of the invention, in described housing low temperature side, be also provided with high temperature insulating material.
According to one embodiment of the invention, liner is connected with the side spot welding at housing expansion joint.
According to one embodiment of the invention, inner cover plate and the high temperature side periphery of being located at housing high temperature side all have gap at width and length direction.
According to one embodiment of the invention, the low temperature side be combined with outer cover plate at housing is provided with web frame.
The present invention can also be:
A kind of high temperature furnace, comprises the above-mentioned high-temperature furnace door with expansion joint.
Compared with prior art, one of beneficial effect of the present invention is:
Of the present invention have in the high-temperature furnace door technical scheme at expansion joint, cleared up unbalanced hot internal stress by expansion joint, thus avoid housing and produce obvious buckling deformation; Simultaneously, the gap of inner cover plate and fire door high temperature side periphery makes inner cover plate at high temperature also retractable and can not produce unbalanced hot internal stress, therefore, the door structure with expansion joint can solve the problem that the sealing device between housing and furnace wall lost efficacy because of the obvious buckling deformation of housing;
In addition, structure of the present invention is simple, easy to use, cost is lower, has good using value.

Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
As shown in Fig. 1 ~ 5, technical scheme of the present invention is achieved in that a kind of high-temperature furnace door with expansion joint, comprise housing 21, the high temperature side 211 that housing 21 is corresponding with the rectangular aperture 12 of body of heater 10 is set to hollow, certain rectangular aperture 12 is according to actual conditions, also can be other shape, and be provided with inner cover plate 23 in high temperature side 211 hollow part, the surrounding facade perpendicular with high temperature side 211 is provided with sealing device 13, be provided with expansion joint 213 in housing 21 high temperature side 211 plane surrounding vertical and horizontal compartment of terrain and extend in the middle part of the facade perpendicular with high temperature side 211, liner 22 is provided with at housing 21 inner surface being provided with expansion joint 213 place, housing 21 low temperature side 212 corresponding with high temperature side 211 is set to hollow, and is provided with outer cover plate 25 in low temperature side 212 hollow part, housing 21 and liner 22, inner cover plate 23, outer cover plate 25 form an airtight cavity, and inside cavity is evenly equipped with high temperature insulating material 26.
Above-mentioned liner 22 is connected with the side spot welding at housing 21 expansion joint 213, to make liner 22 can along mating surface telescopic slide in housing 21.
Above-mentioned inner cover plate 23 all has gap 24 with the hollow part periphery of fire door 20 high temperature side 211 at width and length direction.
For strengthening door structure rigidity, the low temperature side 212 be combined with outer cover plate 25 at housing 21 is provided with web frame 27.
To sum up, the high-temperature furnace door 20 of said structure, when high temperature furnace works, the fire door housing 21 of metal material is interior, high temperature side 211 expanded by heating under outer temperature difference condition, but because housing 21 high temperature side 211 is set to hollow, and be provided with expansion joint 213 in its plane surrounding vertical and horizontal compartment of terrain and extend in the middle part of perpendicular facade, make housing 21 high temperature side 211 can free-extension, namely unbalanced hot internal stress has been cleared up at expansion joint, housing is avoided to produce obvious buckling deformation, and the liner 22 being arranged on expansion joint 213 place is connected with the side spot welding at housing 21 expansion joint 213, make liner 22 can along mating surface telescopic slide in housing 21, meanwhile, the inner cover plate 23 being arranged on high temperature side 211 hollow part all has gap 24 with fire door 20 high temperature side 211 hollow part periphery at width and length direction, i.e. inner cover plate 23 at high temperature also retractable and can not produce unbalanced hot internal stress.Therefore, above-mentioned high-temperature furnace door 20 structure with expansion joint 213, housing 21 can be avoided to produce obvious buckling deformation because of the larger temperature difference in high and low temperature side, thus avoid the problem that the sealing device 13 between housing 21 and furnace wall 11 lost efficacy because of the obvious buckling deformation of housing 21.
In actual applications, fire door can be made to reach best applications effect according to the dimensions at the Parameters variation matching design expansion joints such as furnace body temperature scope, fire door size.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
