Embodiment Construction

[0012] Such as figure 1 As shown, a cement kiln tertiary air duct valve plate includes a metal plate core 1, the metal plate core 1 is in a grid shape, and at least one lifting ring 5 is further provided on the metal plate core 1, and the grid shape It is a regular polygon 4, which can also be a shape. The regular polygon 4 ensures that there is no gap when the valve plate is poured, and the operation is simple and convenient to use. The regular polygon 4 is a square, and the square makes the casting effect best. The lifting ring 5 is welded to the metal The plate core 1 is welded to ensure that the hoisting ring 5 does not fall off and improve the product quality. There are two hoisting rings 5, and the two hoisting rings 5 ​​are evenly distributed on the top of the metal plate core 1, so that the hoisting ring 5 is affected by Uniform force.

[0013] The metal plate core 1 is made of hot steel bars 3 into a square grid shape, two rings are uniformly welded on the top of the me...

Abstract

The invention relates to a cement kiln tertiary air tube valve plate which comprises a metal plate core, wherein the metal plate core is of a gridding shape, and at least one flying ring is arranged on the metal plate core; the valve plate provided by the invention has the advantages that a wear-resisting pouring material is casted in a square gridding shape plate core manufactured by heat-resisting rebar, and the pouring material in the valve plate is uniformly distributed; the structure is stable, the operation is simple, a flying ring is arranged on the top of the valve plate, and the metal plate core is easy to change and maintain; and the valve plate provided by the invention has the characteristics of high strength, high wear resistant, shock resistance, scour resistance, long service life and the like through adopting a high-tensile wear-resisting pouring material.

Description

Technical field [0001] The invention relates to a cement kiln tertiary air pipe valve plate. Background technique [0002] At present, the temperature of the tertiary air duct of cement kiln varies greatly, the wind speed in the tube is high, and the hot air contains a large number of small clinker particles. The tertiary air duct is directly scoured and corroded by the dusty hot air for a long time, and the valve plate lining is very easy to crack , Peeling, resulting in serious wear. In addition, under the action of the tertiary air, the valve plate will continue to sway fiercely back and forth, causing the pouring material to loosen and fall. In severe cases, the valve plate will be deformed and broken, resulting in shortened service life and troublesome maintenance. , Poor security. Summary of the invention [0003] The technical problem to be solved by the present invention is the short service life of a cement kiln tertiary air duct valve plate under the action of tertiary ...
