Reinforcing bar is connected, connection reinforcing bar welds with cylinder of rotary kiln；Bottoming brick is arranged between adjacent fireproof insulation brick row, and bottoming brick edge is returned
Rotary kiln barrel lenght direction is built by laying bricks or stones, and bottoming brick is provided at both ends with the small dovetail groove of outer imperial palace, and fixed steel bars are shaped as V-arrangement, Gu
To determine reinforcing bar to be located in the space of two dovetail grooves formation of adjacent bottoming brick, tip and the cylinder of rotary kiln of fixed steel bars weld,
The both ends of fixed steel bars are higher than bottoming brick, and fixed steel bars push bottoming brick；The height of bottoming brick is less than fireproof insulation brick height, resistance to
Fiery castable fills the remaining space between adjacent fireproof insulation brick row；Each floater guide block ring is set along cylinder of rotary kiln length direction interval
Put and be connected with cylinder of rotary kiln, masonry construction is divided into multistage by floater guide block ring.
It is further：The both ends of fireproof insulation brick bottom part body are each provided with a connection reinforcing bar, and connection reinforcing bar is along resistance to
Fiery insulating brick body width direction sets and extends to fireproof insulation brick body exterior.
It is further：The distance of adjacent floater guide block ring is 30 meters.
The beneficial effects of the invention are as follows：Masonry construction is connected firmly with cylinder of rotary kiln, difficult for drop-off, damaged, and collapse brick；Gear
Brick ring can isolate each section of masonry construction " thermal expansion " caused by internal stress, avoid the internal stress interaction of each section of masonry construction from causing
Masonry construction caused by planted agent is excessive squeezes broken.Therefore the present invention improves masonry of Rotary Kiln structure service life, reduces stove
Build frequency by laying bricks or stones, reduce rotary kiln use cost and idle cost caused by rotary kiln maintenance can be reduced.

Embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
In order to provide a kind of non-damageable masonry of Rotary Kiln structure, as shown in Figures 1 to 5：Masonry of Rotary Kiln structure bag
Include cylinder of rotary kiln 1 and the masonry construction 2 being arranged in cylinder of rotary kiln 1；Also include floater guide block ring 3；Masonry construction 2 includes fire resisting
Insulating brick 21, bottoming brick 22 and fixed steel bars 25；Fireproof insulation brick 21 built by laying bricks or stones along the length direction of cylinder of rotary kiln 1 to be formed it is multiple resistance to
Fiery insulating brick row 24, each fireproof insulation brick row 24 circumference array, fireproof insulation brick 21 centered on the axis of cylinder of rotary kiln 1 include
Fireproof insulation brick main body 211 and the connection reinforcing bar 212 for being arranged on the bottom of fireproof insulation brick main body 211, connection reinforcing bar 212 and revolution
Kiln cylinder body 1 welds；Bottoming brick 22 is arranged between adjacent fireproof insulation brick row 24, and bottoming brick 22 is along the length side of cylinder of rotary kiln 1
To building by laying bricks or stones, bottoming brick 22 is provided at both ends with the small dovetail groove 221 of outer imperial palace, and fixed steel bars 25 are shaped as V-arrangement, fixed steel bars 25
In the space that two dovetail grooves 221 of adjacent bottoming brick 22 are formed, the tip of fixed steel bars 25 is welded with cylinder of rotary kiln 1
Connect, the both ends of fixed steel bars 25 are higher than bottoming brick 22, and fixed steel bars 25 push bottoming brick 22；The height of bottoming brick 22 is less than fire resisting
The height of insulating brick 21, castable refractory 23 fill the remaining space between adjacent fireproof insulation brick row 24；Each floater guide block ring 3 is along revolution
The length direction of kiln cylinder body 1 is arranged at intervals and is connected with cylinder of rotary kiln 1, and masonry construction 2 is divided into multistage by floater guide block ring 3.
The present invention builds fireproof insulation brick 21 and bottoming brick 22 by laying bricks or stones to be combined with the mode of the cast-in-site of castable refractory 23
Masonry construction 2 is formed, is advantageous to prevent the damage of masonry construction 2 from coming off.Fireproof insulation brick 21 and bottoming brick 22 build by laying bricks or stones with it is existing
The masonry way of technology is identical, i.e., is connected fireproof insulation brick 21 and bottoming brick 22 with adjacent structure using castable refractory 23
Connect；The present invention is in addition to traditional build by laying bricks or stones also by under the welding and fixed steel bars 25 that connect reinforcing bar 212 and cylinder of rotary kiln 1
Pressure further fixes fireproof insulation brick 21 and bottoming brick 22, makes the two fixation more firm, difficult for drop-off.The two of fixed steel bars 25
