Abstract
The utility model discloses an annealing furnace for prolonging the service life of a sealing ring. The annealing furnace comprises a rubber sealing ring, an asbestos packing sealing layer, an upper cover and a furnace body, wherein the furnace body comprises a furnace wall, the outer end surface at the top part of the furnace wall is provided with a first annular notch of which the cross section is of an inverted right trapezoid shape, and the inner end surface at the top part of the furnace wall is provided with a second annular notch of which the cross section is of a rectangular shape; the upper cover comprises a cover wall and a cover inside bottom surface, and the cross section of the cover wall is of the inverted right trapezoid shape; and the cover inside bottom surface is in contact with the top end of the furnace wall, the rubber sealing ring is arranged between the first annular notch and the cover wall, and the asbestos packing sealing layer is arranged between the second annular notch and the cover inside bottom surface. According to the annealing furnace for prolonging the service life of the sealing ring, disclosed by the utility model, the temperature of the rubber sealing ring is lowered, and the service life is prolonged.
Description
Technical field
The utility model belongs to the annealing furnace field, is specifically related to a kind of sealing ring annealing furnace in service life that prolongs.
Background technology
Contact furnace wall, two ends up and down and the loam cake of the rubber seal in the existing annealing furnace, and the side of rubber seal is exposed in the furnace chamber, makes the rubber seal temperature too high and aging easily, thus reduce service life.
The utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is the service life that prolongs rubber seal in the annealing furnace.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of sealing ring annealing furnace in service life that prolongs comprises rubber seal, asbestos packing sealant, loam cake and body of heater; Described body of heater includes the furnace wall, and it is the first trapezoidal annular breach of chamfer that the outer face at top, described furnace wall is provided with cross sectional shape, and the inner face at top, described furnace wall is provided with the second annular breach that a cross sectional shape is rectangle; Described loam cake includes tegmental wall and lid inside bottom surface, and the cross sectional shape of described tegmental wall is that chamfer is trapezoidal; Described lid inside bottom surface contacts with the top of furnace wall, and described rubber seal is arranged between the first annular breach and the tegmental wall, and described asbestos packing sealant is arranged between the second annular breach and the lid inside bottom surface.
Described rubber seal upper end contacts with minor axis with the hypotenuse of tegmental wall respectively; Described rubber seal lower end contacts with minor axis with the hypotenuse of the first annular breach respectively.
(3) beneficial effect
The annealing furnace in prolongation sealing ring of the present utility model service life, by the top, furnace wall is contacted with the lid inside bottom surface, make the first annular breach and scarce rubber seal and the asbestos packing sealant of arranging respectively of second annular of the interior outer end at top, furnace wall, thereby make rubber seal and furnace chamber isolated, thereby reduced the temperature of rubber seal, prolonged service life; And first annular breach be the chamfer triangle that cooperates with tegmental wall, rubber seal upper end contacts with minor axis with the hypotenuse of tegmental wall respectively, described rubber seal lower end contacts with minor axis with the hypotenuse of the first annular breach respectively, thereby has improved sealing.
Description of drawings
Fig. 1 is the structural representation of the annealing furnace in prolongation sealing ring of the present utility model service life;
Fig. 2 be the utility model loam cake, body of heater and rubber seal the assembling schematic diagram;
1 is that loam cake, 2 is that body of heater, 3 is that rubber seal, 4 is that asbestos packing sealant, 5 is that furnace wall, 6 is that the first annular breach, 7 is that the second annular breach, 8 is that tegmental wall, 9 is inside bottom surface among the figure.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of sealing ring annealing furnace in service life that prolongs as depicted in figs. 1 and 2 comprises rubber seal 3, asbestos packing sealant 4, loam cake 1 and body of heater 2; Described body of heater 2 includes furnace wall 5, and it is the first trapezoidal annular breach 6 of chamfer that the outer face at 5 tops, described furnace wall is provided with cross sectional shape, and the inner face at 5 tops, described furnace wall is provided with the second annular breach 7 that a cross sectional shape is rectangle; Described loam cake 1 includes tegmental wall 8 and lid inside bottom surface 9, and the cross sectional shape of described tegmental wall 8 is that chamfer is trapezoidal; Described lid inside bottom surface 9 contacts with the top of furnace wall 5, and described rubber seal 3 is arranged between the first annular breach 6 and the tegmental wall 8, and described asbestos packing sealant 4 is arranged between the second annular breach 7 and the lid inside bottom surface 9.
Described rubber seal 3 upper ends contact with minor axis with the hypotenuse of tegmental wall 5 respectively; Described rubber seal 3 lower ends contact with minor axis with the hypotenuse of the first annular breach 6 respectively.
The annealing furnace in prolongation sealing ring of the present utility model service life, by 5 tops, furnace wall are contacted with lid inside bottom surface 9, make the first annular breach 6 and second annular, 7 scarce rubber seal 3 and the asbestos packing sealants 4 of arranging respectively of the interior outer end at 5 tops, furnace wall, thereby make rubber seal 3 and furnace chamber isolated, thereby reduced the temperature of rubber seal 3, prolonged service life; And first annular breach 6 be the chamfer triangle that cooperates with tegmental wall 8, rubber seal 3 upper ends are contacted with minor axis with the hypotenuse of tegmental wall 8 respectively, described rubber seal 3 lower ends contact with minor axis with the hypotenuse of the first annular breach 6 respectively, thereby have improved sealing.
The above only is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
