Specific embodiment
To make content of the present utility model more clear understandable, below in conjunction with Figure of description, to of the present utility model interior
Appearance is described further.Certainly this utility model is not limited to the specific embodiment, known to those skilled in the art
General replacement be also covered by protection domain of the present utility model.Secondly, this utility model has been carried out using schematic diagram in detail
Statement, when this utility model example is described in detail, for convenience of description, schematic diagram should not according to general ratio partial enlargement
In this, as to restriction of the present utility model.
Above and other technical characteristic and beneficial effect, will in conjunction with the embodiments and accompanying drawing 1-3 is to heating of the present utility model
The anti-explosion door structure of stove is described in detail.Fig. 1 is the front view of the anti-explosion door structure of heating furnace of the present utility model；Fig. 2 is
The generalized section of the anti-explosion door structure of heating furnace of the present utility model；Fig. 3 is the local of ratchet and pawl of the present utility model
Enlarged drawing.
As shown in figure 1, this utility model provides a kind of anti-explosion door structure of heating furnace, including gate seat 1 and door closure 2, gate seat 1
It is fixed on heating furnace wallboard by bolt, nuts and washers, the side of door closure 2 is rotatably coupled to by the first pivot pin 3
On gate seat 1.Ratchet 5 is welded on door closure 2 in the present embodiment, ratchet 5 is kept with 3 concentric and with door closure 2 the rotation of the first pivot pin
It is synchronous, ratchet 7 is connected by the second pivot pin 6 on gate seat 1, ratchet 7 can be rotated around the second pivot pin 6 and located at the top of ratchet 5.
Operation principle of the present utility model is：When heating furnace pressure release, ratchet 5 around the first pivot pin 3 rotate counterclockwise with
Door closure 2 is opened, now, ratchet 7 does not affect the rotation of ratchet 5 and the unlatching of door closure 2.When door closure 2 reaches maximum opening, burner hearth pressure
Power reduces, and under gravity, door closure 2 starts return, and ratchet 5 starts to rotate clockwise.Now, ratchet 7 catches on ratchet 5, makes
Which stops operating, and the rotation of door closure 2 also stops therewith, and explosion proof door is maintained at larger opening, can be rapidly completed pressure release.Treat pressure release
It is fully completed, by operator by 2 return of door closure.So avoid rapidly opened and closed the impact to body of heater of explosion proof door and cause stove
The damage of body or explosion proof door, operator also simultaneously can be checked to the state of explosion proof door when to explosion proof door return, if any
Problem is processed in time, is prevented trouble before it happens.
Meanwhile, for the thermal loss for effectively preventing from heating, prevent the surface overtemperature of explosion proof door, be provided with door closure 2 every
Thermosphere 9, thermal insulation layer 9 pass through anchor studs 10 or are threaded on door closure；Preferably, thermal insulation layer 9 be preferably lightening casting material or
The refractory materials such as the fine product of pottery.
In order to prevent gap of the rainwater by door closure 2 with gate seat 1 from penetrating into and the service life of impact refractory material, can be in door
The top of seat 1 is provided with weather shield 4, additionally, in order to prevent the high velocity air sprayed during explosion proof door pressure release to the work near explosion proof door
Damage as personnel, the lower section of gate seat 1 is provided with the arc 8 for preventing air-flow from spraying, and increased the safety of explosion proof door.
In sum, this utility model provides a kind of anti-explosion door structure of heating furnace, by setting on gate seat and door closure
The ratchet and pawl structure for cooperating is put, it is violent to body of heater during when can be prevented effectively from air-flow quick-fried spray, door closure is rapidly opened and closed
Impact and cause the damage of body of heater or explosion proof door, while door closure can be allowed in the quick-fried spray of air-flow to be maintained at a larger aperture, from
And it is rapidly completed pressure release, it is ensured that heating furnace safety；Additionally, the weather shield for arranging can prevent rainwater by door closure and the gap of gate seat
Penetrate into and the service life of impact refractory material.
Although this utility model essentially describes above example, it is intended only as example to be been described by, and this reality
This is not limited to new.For example, each part being shown in detail to embodiment can be changed and be run, with the modification and application
Related difference is believed that and is included in the protection domain of the present utility model limited by claims.
