Technical Field

The invention relates to the field of a tin bath structure, in particular to a bottom brick structure of a tin bath.

Background

The flat glass produced by the float glass production process has good surface quality and high yield, is easy for large-scale automatic production and is widely applied to the production of flat glass for buildings and automobiles all over the world. As a key core device, the quality of the tin bath design greatly influences the stability of glass production and the quality of a final product. Among them, the design of the structure of the groove bottom brick is the important weight of the whole tin groove design.

Usually, the structure of the tank bottom brick mainly comprises the parts of the tank bottom refractory brick, a fixing component thereof, sealing and pouring materials and the like. The structural design of the bottom brick of the existing tin bath basically adopts the mode of leaving a certain vertical expansion joint between adjacent refractory bricks to arrange, when the tin bath is baked or has a power failure, because the temperature of the bottom of the bath is too high, molten tin can flow to the bottom of the brick along the brick joint and contact with a steel plate of a bottom shell to corrode, and the molten tin can corrode and penetrate through the steel plate to leak, thereby bringing great potential safety hazard to normal production. In addition, the use of the existing potting material also has the problem of cracking, and the tin liquid can erode steel components along the cracks to cause tin leakage and bottom brick floating accidents. Therefore, the design of the groove bottom brick structure capable of effectively preventing molten tin from corroding steel components has very important significance on the safe production of the tin groove.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Please refer to the attached drawings. It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention.

As shown in fig. 1-5, the present invention provides a tin bath bottom brick structure, comprising: lay the end brick 1 at the molten tin bath tank bottom and enclose the side wall brick 2 of establishing along the molten tin bath lateral wall, all cooperate through concave step face 3 and boss step face 4 between the adjacent end brick 1, between end brick 1 and the side wall brick 2 and between the adjacent side wall brick 2, seal through the sealing member between concave step face 3 and the boss step face 4.

By adopting the structure of the bottom brick of the tin bath, the adjacent bottom bricks 1, the bottom bricks 1 and the side wall bricks 2 and the adjacent side wall bricks 2 are matched through the concave step surfaces 3 and the convex step surfaces 4, and the concave step surfaces 3 and the convex step surfaces 4 are sealed through sealing elements, so that the downward leakage of molten tin 5 along the brick joints can be effectively prevented, and the corrosion of the molten tin 5 to steel members at the bottom of the bath can be avoided. Compared with the prior art, the invention cancels the pouring of hole sealing materials and edge sealing materials, and avoids the problem that the molten tin 5 erodes the steel member along the crack due to the cracking of the pouring sealing materials.

As a preferred embodiment, the seal in this example comprises a graphite soft felt, as shown in fig. 1. Because the heat conductivity coefficient of the refractory bricks is lower, and the bottom of the groove is provided with a cooling measure, the brick joints below the steps are designed to be as small as possible, and the vertical joints on the steps are conventionally reserved according to the expansion coefficient of the bottom brick 1. In the only small L-shaped gap below the step, the high-purity graphite soft felt 6 is filled to block the risk of downward leakage of the tin liquid 5 by utilizing the characteristic that the tin liquid 5 and the graphite are not infiltrated mutually.

As shown in fig. 5, as a preferred embodiment, the bottom brick 1 and the side wall brick 2 in this embodiment are fixed on the bottom shell steel plate 7 by a connecting member. Specifically, the connecting member in this embodiment includes heat-resistant steel bolt 8, has seted up the round hole on the drain pan steel sheet 7, and countersunk screw hole has all been seted up to the bottom of end brick 1 and side wall brick 2, and the threaded end of heat-resistant steel bolt 8 passes the round hole and twists in the countersunk screw hole.

More specifically, in order to prevent the molten tin 5 from corroding the heat-resistant steel bolts 8 through the gap between the brick structure and the steel bottom shell 7, a high-purity graphite washer 9 is provided on the step surface of the countersunk head screw hole in the present embodiment.

As shown in fig. 3 and 4, as a preferred embodiment, the height of the upper surface of the side wall tile 2 in this embodiment is greater than that of the bottom tile 1, and the tin liquid 5 is contained in the space of the side wall tile 2 higher than the bottom tile 1.

In this embodiment, as shown in fig. 2, in consideration of convenience of on-site assembling work, it is preferable that the orientation of the recessed step surface 3 and the raised step surface 4 of each brick, which are engaged with the adjacent bricks, be designed to be the same in the width direction and the length direction of the tin bath.

The invention can effectively avoid the erosion of the fixed steel parts of the steel shell and the bottom brick 1 at the bottom of the tank caused by the outward infiltration of the molten tin 5 in the production, thereby avoiding the accidents of tin leakage of the molten tin tank and floating of the bottom brick 1 and greatly improving the safety of the production. The filling of hole sealing materials and edge sealing materials is cancelled, the tin infiltration amount of tin liquor 5 infiltrating into the bottom and the edge of the tank bottom brick 1 is reduced, the outward conduction of heat is reduced, the heat insulation performance of the tin tank is improved, the one-time investment in the early stage is saved, and considerable economic benefits are achieved. The bottom brick structure of the tin bath does not need to be rammed, sealed and filled with materials, does not need to be welded with a fixing stud, is time-saving and labor-saving, and is safe and reliable.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
