Mixed masonry method forrefractory material protective lining on outer side of hanging cylinder block

Abstract

The invention relates to a mixed masonry method for a refractory material protective lining on the outer side of a hanging cylinder block, and belongs to the technical field of hanging cylinder type double-chamber vertical kiln production equipment. According to the technical scheme, the mixed masonry method includes the steps that (1) anchoring parts (13) are uniformly fixed to the outer side ofthe hanging cylinder block (9); (2) lower-layer castables (4) are pouredblock by block in the circumferential direction of the outer side of the hanging cylinder block (9) through a steel mold (10); (3) a second refractory ceramic fiber board (3) is laid on the lower-layer castables (4); (4) upper-layer castables (1) are poured on the lower-layer castables (4) block by block through the steel mold(10); and (5) fifth refractory ceramic fiber boards (8) are laid on the outer sides of the upper-layer castables (1) and the outer sides of the lower-layer castables (4). The mixed masonry method forthe refractory material protective lining on the outer side of the hanging cylinder block has the beneficial effects that errors caused by masonry can be reduced, the masonry process is simplified, and the problems that the hanging cylinder block is heated, expanded and deformed, and consequently a refractory material on an outer circle loosens and falls off can be solved.

Description

technical field [0001] The invention relates to a mixed masonry method for the protective lining of refractory materials outside the cylinder body of a suspended cylinder, and belongs to the technical field of production equipment for a suspended cylinder type double-chamber shaft kiln. Background technique [0002] Suspension cylinder type double-chamber shaft kiln is a commonly used industrial kiln, mainly used for calcining limestone. It consists of two cylindrical vertical furnace body and cylindrical suspension cylinder body. , so that limestone (mainly composed of CaCO 3 ) decomposes into quicklime (CaO) and carbon dioxide (CO 2 ). [0003] At present, the masonry of the air duct outside the suspension cylinder body is to use special-shaped bricks and castables. During masonry, four groups of anchors with a width of about 800mm are evenly distributed on the circumference of the suspension cylinder at intervals of 90°, and special-shaped bricks are used in between, a...

AI Technical Summary

Problems solved by technology

In this way, the special-shaped bricks cannot be cut, and the masonry is difficult and the masonry error is large; secondly, in the production, due to the large thermal expansion and deformation of the suspension cylinder body, the outer ring of the refractory material is loose, and the bricks are easy to fall off; moreover, the quantity of special-shaped bricks purchased is small , high precision requirements for dimensional errors, high procurement costs
