Abstract
The invention discloses a method for laying a lining side support block row of a rotary kiln; the method is characterized by comprising the following steps of: welding a first group of anchoring elements of a first row of blocks along a welding reference line, laying the first row of blocks, then welding anchoring elements of a second row of building blocks, laying the second row of building blocks, and carrying out the following steps in the same manner to finish the laying of the first group of blocks; installing side supports and plate kilns on outer side surfaces of the first row of building blocks, laying a next group of building blocks, and carrying out next steps in the same manner till closing a door; and dismantling the side supports, pouring corundum pouring layers and pointing the building blocks. Each side support comprises an upright pole, a push rod, a rotating fastener, a fine adjustment device and a wood springboard, wherein the upright poles are vertically arranged on a kiln shell in a full-length welding manner and are parallel to the building block rows; and one ends of the upright poles are welded on the kiln shell each six meters. The push rod is connected with the upright pole through the rotating fastener; one end of the push rod is connected with the fine adjustment device; the wood springboard is arranged on the side surface of the building block, and the fine adjustment device is adjusted so that the push rods are propped against the building block rows through the wood springboard. According to the method, the building block looseness and the possibility that the kiln shell becomes red after being put into production are avoided, the service life of the rotary kiln is ensured, and the laying construction period is shortened.
Description
Technical field
The present invention relates to the inner liner of rotary kiln building method, is a kind of inner liner of rotary kiln lateral support building block row building method specifically, is applied to pelletizing, cement producing line high temperature, high pressure, rotary kiln refractory block inside lining building construction field that wearing and tearing are big.
Background technology
Building by laying bricks or stones of existing pelletizing, cement producing line rotary kiln refractory block liner is that radially steel pipe and fine setting combined support are installed in rotary kiln inside, holds out against the rotary kiln refractory lining through bidirectional trimming, and refractory lining is not loosening when making rotary kiln dish kiln.Stand in great numbers owing to radial support is staggered, make the interior level transportation of rotary kiln be restricted, installation and dismounting spended time are longer, influence the duration.Simultaneously, when steel pipe was installed radially with the fine setting combined support, local refractory lining building block meeting was loosening, and the mortar joint bonding is bad between the building block, and it is rubescent very easily to occur the rotary kiln kiln shell after the operation, influences the service life of ordinary production and rotary kiln.
Summary of the invention
The object of the invention; It is exactly the above-mentioned shortcoming that exists to prior art; A kind of inner liner of rotary kiln lateral support building block row building method is provided; To prevent effectively not only that the refractory lining building block is loosening, the bad problem of mortar joint bonding between the building block, and to help level transportation in the kiln, shorten and build by laying bricks or stones the duration.
A kind of inner liner of rotary kiln lateral support building block row building method provided by the invention, it is achieved in that at rotary kiln kiln shell inwall bullet establishes a welding datum line parallel with center line.Weld the anchoring piece of first group of first row building block along the welding datum line, build the first row building block by laying bricks or stones.Weld the anchoring piece of secondary series building block again, build the secondary series building block by laying bricks or stones, built first group of building block by that analogy by laying bricks or stones.At the first row building block lateral surface lateral support is installed, the dish kiln is built next group building block by laying bricks or stones, by that analogy, and until closing door.Remove lateral support, cast corundum pouring layer carries out jointing to building block, accomplishes building by laying bricks or stones of inner liner of rotary kiln.Inner liner of rotary kiln lateral support building block row building method carries out as follows:
1, bullet is established the welding datum line
With timber wedge to being inserted between rotary kiln body supporting surface and the kiln body roller, fixing rotary kiln body.Establish a welding datum line parallel at rotary kiln kiln shell inwall bullet with center line, the straight line that plays need qualified through checking.
2, build first group of building block by laying bricks or stones

3, lateral support is installed
After having built first group of building block by laying bricks or stones, whenever adorn 1 lateral support at a distance from 6 meter amperes at the first row building block lateral surface.Said lateral support is made up of vertical rod, push rod, rotary buckle and fine setting.Vertical rod is to be about 60 centimeters Φ 48 pin hand steel pipes, and vertically full weld stands on the kiln shell.Push rod is to be about 80 centimeters Φ 48 pin hand steel pipes, is connected with vertical rod through rotary buckle, and an end is connected with fine setting.Lay wooden springboard in the building block side, the adjustment fine setting makes push rod hold out against the building block row through wooden springboard.
4, build next group building block by laying bricks or stones
Build position to clockwise direction dish kiln to next group with the hoist engine on the operation platform, the hoist engine pinning is fixed.To being inserted between kiln body roller and the rotary kiln supporting surface, jam-pack is fixed with timber wedge.Build next group building block by laying bricks or stones.Coil kiln again, build by laying bricks or stones again, by that analogy,, close door until building last row building block of accomplishing last group by laying bricks or stones,
5, remove lateral support
To horizontal level, between kiln body roller and rotary kiln supporting surface,, make the kiln body stable in last row building block dish kiln to the tight timber wedge of connector.Remove lateral support and wooden springboard, do not building the zone cast corundum pouring layer of building block by laying bricks or stones.Jointing is carried out in building block, and cleaning kiln body is inner, and building by laying bricks or stones of inner liner of rotary kiln accomplished in acceptance(check).The mortar plumpness requires to reach 95%, and mortar joint is controlled at 2mm ± 1.
Advantage compared with prior art of the present invention is: all carry on the back near reality between building block and anchoring piece, building block and the building block, avoided the loosening and rubescent possibility of back kiln shell of going into operation of building block, guarantee rotary kiln service life.Improved horizontal transportation environment in the kiln, saved and installed and remove the time of supporting, shortened and built by laying bricks or stones the duration.
