An atmosphere furnace door sealing device comprises a furnace body and a furnace door. A furnace port is arranged on the furnace body, a portion, abutted against the furnace body in a pressed manner, of the inner portion of the furnace door is called a furnace door inner edge, the outer side of the furnace door is fixedly connected with more than two mechanical sealing strips horizontally, two ends of each mechanical sealing strip extend out of the furnace door, a U-shaped notch is arranged at each of the two ends of each mechanical sealing strip, and fastening screws are connected on the furnace body and detachably connected with the U-shaped notches through nuts. The atmosphere furnace door sealing device has the advantages that sealing of an atmosphere furnace is realized through a mode of fitted sealing and mechanical sealing to achieve sealing effect during use, mechanical sealing is simple and practical, a graphite packing in fitted sealing is less prone to wearing and aging deformation and capable of resisting high temperature for a long time.
Description
Technical field
The utility model relates to the furnace door sealing device of atmosphere furnace or vacuum drying oven.
Background technology
The body of heater of atmosphere furnace is mainly made up of structures such as burner hearth, heater, fire door and sealing doors.Atmosphere furnace burner hearth need to maintain certain pressure or particular atmosphere, therefore require burner hearth to there is good sealing effectiveness, require will maintain uniform temperature field in stove simultaneously, adopt the easy at high temperature fire door place of water-cooled furnace door to occur sublimating of Cucumber, thereby some situation should not adopt water-cooled furnace door.The fire door of atmosphere furnace is reinforced and the access way of production operation, and fire door is parallel with fire door and can horizontally openable, and a circle rubber laminating encapsulant is installed at the fire door edge of pressing close to fire door one side, and its Main Function is and fire door laminating realizes and sealing.Rubber laminating encapsulant is due to the frequent unlatching of fire door, and mechanical wear is serious, and when furnace temperature is higher, easy agingly causes seal failure, therefore needs frequent replacing.Outside at fire door is welded with mechanically-sealing apparatus, although taked anti-deformation measure, fire door is still easily distortion under long-time hot conditions, has a strong impact on atmosphere furnace sealing effectiveness in use.China utility patent application CN201852461U(application number 201020602490.X) " packing sealing structure of smelting furnace door " only adjust the packing sealing structure of fire door, and the gluing, sealing material to fire door and mechanical seal content are not improved; China utility patent application CN202947475U(application number 201220607326.7) " sealing device of fire door " be provided with dovetail groove on body of heater, and corresponding position is provided with boss on fire door, realize sealing, hermetically-sealed construction is comparatively complicated, and fire door cannot ensure that after slight deformation boss engages with the accurate of dovetail groove, does not reach sealing effectiveness.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, good airproof performance, long-lived atmosphere furnace furnace door sealing device.
The technical solution of the utility model is:
A kind of atmosphere furnace furnace door sealing device, comprise body of heater and fire door, body of heater is provided with fire door, the part that the inner side of fire door and body of heater press is called edge in fire door, outside described fire door, level is fixedly connected with two above mechanical seal bars, and fire door is all stretched out at the two ends of every mechanical seal bar, and the two ends of mechanical seal bar are equipped with U-shaped breach, on described body of heater, be connected with fastening screw, described fastening screw removably connects by nut and U-shaped breach.
Fire door inner peripheral is provided with a circle dovetail groove, and the opening part width of dovetail groove is less than the bottom width of dovetail groove, is pressed with graphite packing in described dovetail groove.
Described body of heater is provided with contiguous block, and described contiguous block is provided with the hole for wearing fastening screw.
Advantage of the present utility model and good effect: the utility model is realized the sealing of atmosphere furnace by the mode of gluing, sealing and mechanical seal, reach use sealing effectiveness, mechanical seal is simple and practical, and gluing, sealing graphite packing is difficult for wearing and tearing, aging distortion, and can be high temperature resistant for a long time.
1, this atmosphere furnace oven door sealing structure, size to fire door metallic plate is thickeied, not only increase the intensity of fire door, and increase the rigidity of fire door, ensure that fire door has good mechanical performance under hot conditions, can prevent that fire door from causing larger distortion in frequent hot conditions use procedure, improved sealing effectiveness.
2, this atmosphere furnace oven door sealing structure, adopt graphite packing as gluing, sealing material, graphite packing has resistant to elevated temperatures performance, and gluing, sealing, wearability are better, and the problem of the heavy wear occurring without rubber gluing, sealing and high temperature ageing distortion, makes oven door sealing structure more durable.
3, this atmosphere furnace oven door sealing construction machine sealing adopts metal poker to be welded on fire door metallic plate, compares while adopting billet welding fire door stressed more even, prevents from that fire door from using for a long time under hot conditions to deform because of unbalance stress.

Detailed description of the invention
As shown in Figure 1, the utility model comprises body of heater 1 and fire door 2, and body of heater 1 is provided with fire door 3, and while closing, the inner side of fire door 2 is pressed on fire door 3, and the area of fire door 2 is greater than the area of fire door 3.The part that fire door 2 medial surfaces are pressed in fire door 3 oral area peripheries is called in fire door along 4.As shown in Figure 4, in fire door, along being provided with a circle dovetail groove 5 along periphery on 4, dovetail groove 5 is trapezoidal groove, and trapezoidal direction is for from inside to outside dwindling, and the interior employing graphite of groove 5 packing 6 is as gluing, sealing material, and graphite packing 6 is pressed in dovetail groove 5.
As shown in Figure 2,3 in the outside of fire door 2, there are two horizontal weldings to be connected on the mechanical seal bar 7 on fire door 2, respectively there is a U-shaped breach 8 at sealing strip 7 two ends, and grow fire door 2 both sides (being the outer position that U-shaped breach 8 is positioned at fire door 2 both sides), on body of heater 1, corresponding each U-shaped breach 8 is equipped with a contiguous block 9, perforate on contiguous block 9, is inserted with fastening bolt 10 in hole, by nut and fastening bolt 10, mechanical seal bar 7 and fire door 2 are sealed with body of heater 1.
The structure that the utility model adopts gluing, sealing to be combined with mechanical seal.Graphite packing for gluing, sealing is not only wear-resisting, high temperature resistant, and is difficult for aging distortion, and graphite packing 6 is pressed in dovetail groove 5, can play good sealing effectiveness, and changes conveniently; For the mechanical seal bar 7 of mechanical seal, adopt the mode of welding to be fixed on fire door 2, technique is simple, is easy to processing, and makes fire door 2 stressed evenly, can ensure the sealing effectiveness of fire door 2 under long-time high temperature pressure condition.
