Description
Technical field
The utility model relates to the rotary kiln fields of metallurgy industry, and in particular to rotary kiln insulating refractory kiln-lining brick.
Background technique
Currently, metallurgy industry is used for the rotary kiln lining brick of pelletizing production, mainly have fix two with kiln body at 3 points, 4 points
Kind, fixed form is welding.Both kiln-lining bricks require after fixing (welding) with kiln body using amorphous refractory
Fill fixed operation (welding) space of fixed point.And the construction of amorphous refractory, anchoring piece is first welded in kiln body,
Then amorphous refractory is poured again.Since pouring for amorphous refractory can only carry out in the specific position of rotary kiln,
It just can be carried out the construction of next kiln position after amorphous refractory solidification after pouring.Different indefinite form fire resistings
The setting time of material is variant, and between generally 2-4 hours, therefore, the masonry of rotary kiln liner is discontinuous.Indefinite form
Refractory material has different proportions according to requirements, it is simultaneously solid to exclude moisture by the baking that is gradually warmed up being adapted therewith
After knot, requirement can be only achieved.It heats up time of baking, not according to the proportion of amorphous refractory and requirement
Together, generally between 120 hours to 240 hours.With both kiln lining brick masonry rotary kiln liners, it is longer to build the time.Due to
Amorphous refractory is to be stirred, pour and toast at the construction field (site), and service life is passed through in process of factory production
The kiln-lining brick of oversintering is variant, and repairing could continue to produce several times for the progress that stop production after damage.
Utility model content

Specific embodiment
Below in conjunction with attached drawing, specific embodiment of the present utility model is explained:
4 points of fixed rotary kiln liner bricks, including ontology 1 and metal external member 2, ontology wrap up metal external member moulding by casting.
The ontology of kiln-lining brick is fan-shaped, internal diameter, that is, rotary kiln inside radius of ontology, wall in body diameter and rotary kiln body
Radius is consistent.Ontology is made of the heavy flame retardant coating 3 of inside and the light-weight refractory layer 4 in outside, light-weight refractory layer 3 and heavy fire resisting
Layer 4 is sintered by lightweight refracrory and heavy refractory material casting respectively, thickness proportion required according to different process and
Depending on kiln body insulation requirement.Metal external member 2 is located in light-weight refractory layer 3 and heavy flame retardant coating 4 simultaneously, can prevent ontology hierarchy
Rupture.
Metal external member 2 includes two fixed anchors 21, and two fix between anchors 21 by 22 reinforcement by connection of anchoring piece connector.Gu
Determining anchor 21 is trapezoidal bending part, and fixed 21 bottom end of anchor is interconnecting piece 23, and the section of stretching out 24 on fixed 21 top of anchor is welded with
Connector sleeve 25, the connector sleeve 25 and interconnecting piece 23 of same fixed anchor 21 are coaxial.Anchoring piece connector 22 is one group of " W " type bending
Part 26, the end of two " W " type bending parts 26 is by 27 reinforcement of weld of connecting rod, two bending point spacing of " W " type bending part and fixed anchor
Two bending point spacing of part are equal, and two bending points of each " W " type bending part are spot welded with corresponding fixed two bendings of anchor
It is fixed；The integral type robust structure that four pads are welded to connect is formed between anchoring piece connector and two fixed anchors.
Ontology bottom surface is equipped with a pair of of groove 5, and the interconnecting piece 23 of each fixed 21 bottom end of anchor protrudes into groove 5 but not from ontology
Outer body is stretched out, the connector sleeve on fixed anchor top stretches out the outside of body top surface, and ontology 1 is tightly attached in 25 one end of connector sleeve,
23 outer diameter of interconnecting piece is slightly less than 25 internal diameter of connector sleeve.
Two fixed 21 place planes of anchor correspond to the center of circle that the central angle of rotary kiln axis corresponds to rotary kiln center for ontology
The half at angle.So when kiln-lining brick is piled up, the two-phase of kiln-lining brick bottom surface two interconnecting piece 23 and two pieces of kiln-lining brick top surfaces below
Adjacent connector sleeve 25 patches cooperation, two abutting connections 23 of kiln-lining brick top surface two connector sleeves 25 and its two pieces of kiln-lining brick bottom surface in top
Cooperation is patched, four point attachment is formed and fixes.
In order to avoid the gap of interlayer exists, the length of fixed anchor 21 is equal to 1 height of kiln-lining brick ontology and adds connector sleeve
25 length.The width of groove 5 is slightly larger than the outer diameter of connector sleeve, usually stays 2mm surplus.The height of groove slightly larger than connector sleeve and
The sum of interconnecting piece outer diameter usually stays 2mm surplus.
The kiln-lining brick manufacturing process are as follows: fixed anchor 21, anchoring piece connector 22 and connector sleeve 25 are welded into one
Whole metal external member 2 is avoided in the external coating pitch of metal external member 2 due to metal material and refractory expansion coefficient
Difference, by refractory material spalling after metal material is heated, coating thickness is according to metal parts and the coefficient of expansion of refractory material
Depending on being required with technique；Metal external member 2 after coating is put into kiln lining brick shaping mould, lightweight refracrory is poured, to cold
But it is poured heavy refractory material again after forming, is demoulded after molding to be cooled, the sinter molding after spontaneously drying.
The mode for the prefabricated kiln-lining brick that the technical program is taken starts the construction of rotary kiln after the completion of kiln-lining brick is prefabricated,
Its work progress are as follows:
Kiln-lining brick is built in rotary kiln radially to be organized circlewise, and general every piece of kiln-lining brick is relative to rotary kiln center
Central angle is 8 degree, and 45 pieces of kiln-lining bricks can form the first ring of bottom as starting ring.
The masonry of first ring is as follows: it requires to be uniformly distributed one circle connector sleeve 25 of welding according to size on cylinder of rotary kiln,
In the connector sleeve that the projecting inward connecting component insertion of kiln-lining brick bottom recesses has been welded in kiln body, by consolidating for kiln-lining brick top surface
Surely set side is welded and fixed with kiln body.Complete the masonry of the first ring.
The position of second ring kiln-lining brick axially offsets 4 degree of angles in rotary kiln with the first adjacent ring kiln-lining brick, by the second ring
The projecting inward interconnecting piece of kiln-lining brick upper groove is inserted into the connector sleeve of the first ring kiln-lining brick, by the connector sleeve side of second layer kiln-lining brick
Face and kiln body are welded.Complete the masonry of the second ring.
And so on, the kiln-lining brick of adjacent ring misplaces 4 degree respectively, it is ensured that and adjacent layer interannular interconnection improves stability,
Until completing the masonry of whole kiln-lining bricks.
The kiln-lining brick of the technical program may be implemented continuously to construct in the construction process, without using amorphous refractory
The fixed operation space of fixed point is filled, it is uniform in material, without until amorphous refractory material solidification, saving construction
Between.The upper and lower surface of each layer kiln-lining brick forms at 4 points with upper and lower interlayer respectively and plugs together fixation, is welded and fixed between outer ring and kiln body, ties
Structure is stablized.
The technical program may be equally applied to the rotary kiln of cement industry or other industries.
