Abstract
The utility model provides a top wall structure of an annealing kiln D area, which comprises a plurality of top cross beams, a hanging bottom beam and a cover plate, wherein the top cross beams are parallel to one another and are arranged at intervals; the hanging bottom beam is connected right below the top cross beam, and two sides of the hanging bottom beam are connected with the top of the side wall of the D area of the annealing kiln; the cover plate is positioned between any two adjacent top cross beams and is placed on the hanging bottom beam. The utility model has the advantages that the hanging bottom beam is additionally arranged at the bottom of the top cross beam, and the cover plate is placed on the hanging bottom beam, so that the top cross beam can be prevented from directly contacting with the side wall and high-temperature air flow in the D-zone kiln body, the temperature of the top cross beam is greatly reduced, the structure is more stable, and the deformation degree is greatly reduced.
Description
Technical Field
The utility model relates to the technical field of glass annealing kilns, in particular to a top wall structure of an annealing kiln D area.
Background
The annealing lehr is one of the core devices of a glass production line, and is located after the tin bath, and the main purpose is to provide a stable annealing environment for the glass, and to control the thermal stress in the molten glass ribbon within an allowable range. In the lehr, transition zone D is an important part of the lehr, and it is not only the transition zone between the thermal radiation cooling zone and the forced cooling zone, but also serves as a partition.
The top wall of the existing annealing kiln D area comprises a top cross beam and a cover plate, wherein the cover plate is placed on the section steel of the top cross beam and is of a detachable structure and used for sealing the top of the annealing kiln. Because the top cross beam directly contacts with the inside of the D area, the middle part of the top cross beam collapses after being heated, and serious deformation is generated, so that the problems that the structure of the kiln body is deformed, and the retaining curtains and other equipment arranged on the top wall cannot be operated are caused.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned drawbacks, the present invention aims to provide a top wall structure of annealing kiln D zone with less deformation after heating.
The utility model provides a top wall structure of an annealing kiln D area, which comprises a plurality of top cross beams, a hanging bottom beam and a cover plate, wherein the top cross beams are parallel to one another and are arranged at intervals; the hanging bottom beam is connected right below the top cross beam, and two sides of the hanging bottom beam are connected with the top of the side wall of the annealing kiln D area; the cover plate is positioned between any two adjacent top cross beams and is placed on the hanging bottom beam.
Preferably, the hanging bottom beam and the cover plate are both filled with aluminum silicate fiber blankets.
Preferably, the hanging bottom beam is detachably connected with the top cross beam through a connecting piece.
The utility model has the beneficial effects that the hanging bottom beam is additionally arranged at the bottom of the top cross beam, and the cover plate is placed on the hanging bottom beam, so that the top cross beam can be prevented from directly contacting with the side wall and high-temperature air flow in the kiln body in the D area, the temperature of the top cross beam is greatly reduced, the structure is more stable, and the deformation degree is greatly reduced.

Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.
In the description of the present invention, it should be noted that the terms "top", "bottom", "inside", "outside", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
As shown in fig. 1 and 2, the present invention provides a top wall structure of an annealing kiln D zone, which includes a plurality of top cross members 1, hanging bottom cross members 2, and a cover plate 4. Wherein, top beam 1 is the I-steel, and a plurality of top beam 1 are parallel to each other and the interval sets up. Hang floorbar 2 and be panel, it can dismantle through connecting piece 3 and connect under top crossbeam 1, and connecting piece 3 preferably includes backing plate and bolt and nut, and its quantity can be adjusted as required in practical application, conveniently adjusts hookup location simultaneously. The top cross beam 1 and the hanging bottom beam 2 can be welded together by those skilled in the art according to the requirement, or can be detachably connected by other methods such as sliding fit. The two sides of the hanging bottom beam 2 are connected with the top of the side wall 5 of the annealing kiln D area, so that the direct contact between the top beam 1 and the side wall 5 is avoided. The cover plate 4 is positioned between any two adjacent top cross beams 1 and is placed on the hanging bottom beam 2.
In the specific implementation, the hanging bottom beam 2 and the cover plate 4 are both filled with a refractory heat-insulating material, and the refractory heat-insulating material is preferably an aluminum silicate fiber blanket, so that the hanging bottom beam 2 and the cover plate 4 are prevented from being deformed by heat.
According to the utility model, the hanging bottom beam 2 is added on the top wall structure of the D area of the existing annealing kiln, so that the top beam 1 is prevented from directly contacting with the side wall 5 and high-temperature air flow in the kiln body of the D area, the temperature of the top beam 1 is greatly reduced, the structure is more stable, and the deformation degree is also greatly reduced.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
