Problems solved by technology

Due to the vibration when the preheater is unloading, there is no way to eliminate the influence of the unloading vibration on the existing hanging brick knotted castable roof structure, which will cause cracks and fire on the furnace roof due to the vibration, resulting in the roof masonry life not exceeding one year
Seriously affect the normal operation of the preheater

Embodiment Construction

[0009] As shown in the drawings, the upper part of the furnace roof is built with a large I-beam 1, the lower end of the large I-beam 1 is fixed by the upper anchor 2 to the upper end of the small I-beam 3, and the lower end of the small I-beam 3 is fixed by the lower anchor 4 Wedge anchor brick Y4 and main anchor brick Y3. Anchor brick Y2 is inlaid between wedge-shaped anchor brick Y4, main anchor brick Y3 and two main anchor bricks Y3, and light is filled between wedge-shaped anchor brick Y4 above anchor brick Y2, main anchor brick Y3 and two main anchor bricks Y3. Quality castable 5. The wedge-shaped anchor brick Y4 is used to connect surrounding castables. The main anchor brick Y3 and the anchor brick Y2 are dumbbell-shaped, and one side of the wedge-shaped anchor brick Y4 is dumbbell-shaped. The main anchor brick Y3, anchor brick Y2 and wedge-shaped anchor brick Y4 can also be in zigzag shape, candied haws shape or other shapes capable of realizing convex-concave connec...

Abstract

The invention relates to a furnace top of a preheating furnace, in particular to a furnace top masonry structure. The upper part of the furnace top is constructed by a large joist steel, the lower end of the large joist steel is fixed with the upper end of a small joist steel through an upper anchoring piece, the lower end of the small joist steel is fixed with a wedge-shaped anchoring brick Y4 and a main anchoring brick Y3 through a lower anchoring piece, anchoring bricks Y2 are embedded between the wedge-shaped anchoring brick Y4 and the main anchoring brick Y3 and between two main anchoring bricks Y3, light pouring materials are filled between the wedge-shaped anchoring brick Y4 and the main anchoring brick Y3 which are positioned above the anchoring bricks Y2 and between the two main anchoring bricks Y3 positioned above the anchoring bricks Y2, and the wedge-shaped anchoring brick Y4 is used for connecting the surrounding pouring materials. The invention has shock absorption and long service life.

Description

technical field [0001] The invention relates to a furnace roof of a preheating furnace, in particular to a furnace roof masonry structure. Background technique [0002] The top masonry of the preheater of the existing lime production line adopts the form of hanging bricks and knotted castables, that is, the hanging bricks are fixed first, and then the mold is supported, and the castables are knotted to form a furnace roof masonry structure. Due to the vibration when the preheater is unloading, there is no way to eliminate the influence of the unloading vibration on the existing hanging brick knotted castable roof structure, and cracks and fire will occur on the furnace roof due to the vibration, resulting in the roof masonry life not exceeding one year. Seriously affect the normal operation of the preheater. Invention content: [0003] In order to overcome the disadvantages of the prior art, the present invention provides a preheating furnace roof, which can absorb shock...
