Description
Technical field
The utility model belongs to the metallurgy industry production facility, is specifically related to a kind of well formula slow cooling annealing furnace lid leak tight structure.
Background technology
Shown in Figure 1, existing well formula slow cooling annealing furnace lid leak tight structure is the sealing of individual layer sand seal, and its resistance to air loss is relatively poor, and airborne oxygen also can be penetrated in the stove by the leak point, causes the steel piece surface oxidation, thereby influences quality product.
Summary of the invention
The utility model provides a kind of well formula slow cooling annealing furnace lid leak tight structure, and it is a double-layer sealing structure, and it has the characteristics of good sealing effect, long service life.
It comprises interior doughnut-shaped steel plate, first annular pressing plate, outer ring steel plate the utility model, interior doughnut-shaped steel plate, outer ring steel plate all are positioned on the body of heater, the outer ring steel plate is positioned at the outside of doughnut-shaped steel plate, fixedly connected with body of heater respectively in the lower end of the lower end of interior doughnut-shaped steel plate, outer ring steel plate, constitute first annular recesses between interior doughnut-shaped steel plate and the outer ring steel plate, it is characterized in that: be filled with ceramic fiber in first annular recesses, fixedly connected with the housing of bell in the upper end of first pressing plate, the lower end of first pressing plate is positioned at first annular recesses and is pressed on the ceramic fiber; The outside of outer ring steel plate is provided with the 3rd doughnut-shaped steel plate, and the 3rd doughnut-shaped steel plate is positioned on the body of heater, and the 3rd doughnut-shaped steel plate is fixedlyed connected with body of heater, constitutes second annular recesses between the 3rd doughnut-shaped steel plate and the outer ring steel plate, is filled with silicon rubber in second annular recesses; The outside of first pressing plate is provided with second pressing plate, and second pressing plate is annular shape, fixedlys connected with the housing of bell in the upper end of second pressing plate, and the lower end of second pressing plate is positioned at second annular recesses and is pressed on the silicon rubber.
Described doughnut-shaped steel plate can be annular, rectangle annular, square annular and other shape that matches with well formula slow cooling annealing furnace bell.
Because of the first layer sealed structure is the ceramic fiber sealing; utilize the resistance to elevated temperatures of ceramic fiber; so the first layer sealing can reduce contacting of protective atmosphere and second layer sealing material greatly; improve the work-ing life of second layer sealing material; and second layer sealing material (silicon rubber) stopping property is fine, can play the tight effect of sealing.The utility model adopts double-layer sealing structure, and its sealing effectiveness is better, longer service life.
