In embodiment or description of the prior art, the required accompanying drawing used is briefly described, it should be apparent that below,
Accompanying drawing in description is only embodiments more of the present utility model, comes for those of ordinary skill in the art
Say, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the present embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is carried out clear, complete
Ground describes, it is clear that described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creation
Property work premise under the every other embodiment that obtained, broadly fall into the scope of this utility model protection.
Shown in Fig. 1, the isolating device being applicable to continuous annealing furnace that the present embodiment provides, including on stove
Lid 1 and two baffle plates 2.The cross section of stove top case 1, in " T " font, the most separately sets gas passage
11, gas passage 11 makes the bottom of stove top case 1 communicate with top.Gas passage 11 include lower end passage 111,
Middle-end passage 112 and Upper passage 113.Lower end passage 111, middle-end passage 112 and Upper passage 113
Cross section is circle.Controling of the pressure of the oven baffle plate 12 is fixed in the junction of lower end passage 111 and middle-end passage 112.
Fix furnace pressure in the junction of middle-end passage 112 with Upper passage 113 and cut baffle plate 13 soon.At Upper passage 113
Top fixing point firearm 14, by lighter 14 light the furnace gas containing combustible component can ensure safety and
Environmental protection.
At the top of stove top case 1, i.e. the header portion both sides of " T " font offer through hole 15 respectively.Each
The top of through hole 15 arranges worm and gear elevating mechanism 16.The floor installation of worm and gear elevating mechanism 16 exists
The top of through hole 15, the bottom fixed dam 2 of its elevating lever.Baffle plate 2 can be along stove in lifting process
The side of the vertical beam part of upper cover 1 " T " font slides.During the electric machine rotation of worm and gear elevating mechanism 16,
Drive worm and gear lifts, and makes baffle plate 2 can lift in the range of 0-100mm.When two baffle plates
Can rise or fall respectively along the both sides of stove top case 1, in order to ensure the sealing of the present embodiment and prevent
The bottom of baffle plate 2 scratches steel band 6, pastes refractory fiber blanket 21 in the bottom of baffle plate 2.
Also including furnace bottom 3 in the present embodiment, furnace bottom 3 offers groove 30.Hearth roll 31 is set in groove 30.
Upper surface at furnace bottom 3 pastes one layer of refractory fiber blanket 32.Refractory fiber blanket 32 can be by whole furnace bottom 3
Upper surface all covers, it is also possible to be placed only in the surface of furnace bottom 3 top.In one stove section of continuous annealing furnace
Steel band 6 entered in the present embodiment by hearth roll 31, then export to continuous annealing furnace from the present embodiment
In another stove section.Steel band 6 is during transmitting, if touching refractory fiber blanket 32, it is ensured that steel band 6 is not
Can receive and scratch.
The present embodiment in use, is placed between two stove sections of continuous annealing furnace, is carried out by airtight and watertight padding
Connect.Cover one layer of sand seal 4 in the junction of the present embodiment with continuous annealing furnace, also cover on the upper strata of sand seal 4
Cover one layer of water seal 5, make continuous annealing furnace be tightly connected with the present embodiment.The both sides of furnace bottom 3 respectively with move back continuously
The furnace bottom of the different stove sections of stove connects.
When two baffle plates 2 all decline, baffle plate 2 the stove section of continuous annealing furnace is separated into forehearth section P1 and after
Stove section P3.Between two baffle plates 2, i.e. the inside of the present embodiment is distance piece P2.Use controling of the pressure of the oven baffle plate
Gas in distance piece P2 is discharged by 12 by gas passage 11, makes the air pressure of distance piece P2 less than forehearth section
Air pressure in P1, rear stove section P3, i.e. P2 ＜ P1 and P2 ＜ P3.Atmosphere in forehearth section P1 flows to isolation
Section P2, the atmosphere of rear stove section P3 also flows to distance piece P1.After so the atmosphere of forehearth section P1 would not flow into
Stove section P3, the atmosphere of rear stove section P3 is the most such.Thus the atmosphere realizing former and later two stove sections is gone here and there the most mutually and obscures,
Also completely cut off forehearth section P1, the furnace temperature of rear stove section P3 makes its non-interference simultaneously, it is achieved thereby that not equality of temperature
The Atmosphere controlling heat-treatment of degree different atmosphere.When forehearth section P1, after atmosphere in stove section P3 all flow into distance piece
During P2, the atmosphere pressures in distance piece P2 raises, and now needs to control controling of the pressure of the oven baffle plate 12 again by gas
Atmosphere is discharged, it is also possible to uses furnace pressure to cut baffle plate 13 soon and assists controling of the pressure of the oven baffle plate 12 by the gas in distance piece P2
Atmosphere is discharged.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model is also
Be not limited to this, any those familiar with the art in the technical scope that this utility model discloses,
Change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, this reality
Should described be as the criterion with scope of the claims with novel protection domain.
