Embodiment Construction

[0032] Below in conjunction with embodiment the present invention is described in further detail:

[0033] 【Example】

[0034] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the rotary kiln masonry structure and masonry method include the following steps:

[0035] A. Place the kiln body 1 horizontally, divide the inner surface of the kiln body 1, set a horizontal pouring area 3 every 60° along the circumferential direction on the inner surface of the kiln body 1, and the horizontal pouring area 3 extends through the entire kiln body in the axial direction 1, the inner surface of the kiln body 1 is provided with a plurality of longitudinal pouring areas 4 arranged at intervals along the axial direction, and the longitudinal pouring areas 4 extend 360° along the circumferential direction. The other regions of the vertical pouring zone 4 are the welding zone 5;

[0036] B. Locate and mark the welding points on the welding area 5. The welding points are used to...

Abstract

The invention discloses a masonry method for rotary kilns. The masonry method includes steps of (1), dividing areas; (2), welding anchoring parts; (3), mounting precast bricks; (4), pouring mortar. The masonry method has the advantages that integral precast brick layers are divided into a plurality of areas, when the precast bricks in a certain area fall off, the integrity of the other areas can be guaranteed, accordingly, the cost can be saved, and workload on workers can be reduced; mortar joints are reserved among the various adjacent precast bricks, so that the integrity of the rotary kilns can be corrected, and accidents caused by the fact that only refractory mortar in joints is squeezed when existing precast bricks are heated and expanded, and the existing precast bricks are squeezed by one another, are broken and fall off can be prevented; the precast bricks are fixed to kiln bodies by the aid of the anchoring parts, so that joints among the precast bricks and the inner walls of the kiln bodies can be set and prevent the precast bricks from squeezing the inner walls of the kiln bodies when the precast bricks are radially expanded, and accidents caused by the fact that the inner walls of existing kiln bodies are squeezed by the existing precast bricks and anchoring parts are broken can be prevented.

Description

technical field [0001] The invention relates to a masonry method, in particular to a rotary kiln masonry method. Background technique [0002] Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to the category of building materials equipment. Rotary kiln can be divided into cement kiln, metallurgical chemical kiln and lime kiln according to different materials. Cement kilns are mainly used for calcining cement clinker, which can be divided into two categories: dry production cement kiln and wet production cement kiln. Metallurgical and chemical kilns are mainly used for magnetization roasting of lean iron ore in iron and steel plants in the metallurgical industry; oxidative roasting of chromium and nickel-iron ore; roasting of high-alumina bauxite in refractory plants and clinker and aluminum hydroxide in aluminum plants; roasting of chromium ore in chemical plants And minerals such as chromium ore powder. Lime kiln (i.e. active lim...
