Abstract
The utility model relates to a fireproof prefabricated brick for a rotary kiln. The fireproof prefabricated brick comprises a prefabricated brick body, wherein the prefabricated brick body is a cuboid with an isosceles-trapezoid-shaped cross section; the bottom surface of the prefabricated brick body of the cuboid structure is arc-shaped; a first groove, a first flange, a second groove and a second flange are respectively arranged on four surfaces between the upper surface and the lower surface of the prefabricated brick body; a bottom supporting base is arranged below the prefabricated brick body; and an anchoring card hole is formed in the bottom supporting base in a direction which is parallel to a circumferential direction of the rotary kiln. The bottom supporting base is arranged at the bottom of the prefabricated brick body and the anchoring card hole is pre-formed in the bottom supporting base in the direction which is parallel to the circumferential direction of the rotary kiln; an anchoring card is tightly matched with the anchoring card hole and the prefabricated brick body is firmly fixed on a cylindrical wall of the rotary kiln; and the welding direction of the anchoring card is vertical to the axial direction of the rotary kiln so that an anchoring piece is firmly contacted with a kiln body.
Description
Technical field
The utility model relates to a kind of preformed bricks, is specifically related to a kind of rotary kiln fire-resisting prefabricated brick.
Background technology
Existing rotary kiln refractory lining masonry way mainly contains two kinds, and a kind of is to adopt wedge shape refractory brick ring block or the fissure of displacement to build by laying bricks or stones, and this kind mode causes easily to draw lots and peels off, and service life is low, and maintenance cost is high.A kind of is to adopt row's preformed bricks one row castable is compound to build by laying bricks or stones, the thermal conductivity factor of anchoring piece is high in this kind structure, it is large to conduct heat, the equipment outside wall temperature is high, energy loss is serious, and the coefficient of expansion of joining reinforcing bar and castable in the while is different, and the reinforcing bar coefficient of expansion is large under the high temperature, preformed bricks is produced structural deterioration, affect kiln service life.
At present, occur a kind of high temperature on the market and burn till refractory brick, by anchoring piece fix and refractory brick between groove and flange, make refractory brick in conjunction with as a whole, solved some drawbacks of original masonry way.There are the following problems but this patented technology is aspect refractory brick fixing: refractory brick is fixed on the kiln body by anchoring piece, leave heat-insulation layer between kiln body and the prefabricated component, because of heat-insulation layer intensity under the condition of high temperature low, in use powder gradually, lose original intensity, cause forming between former anchoring piece and the refractory brick loosening, it no longer is tight connection between anchoring piece and the refractory brick, dynamic operation condition condition at rotary kiln, refractory brick rotates with the kiln body, reciprocating extrusion anchoring piece, anchoring piece intensity under the condition of high temperature descends, and last and kiln body breaks away from; It is axial that the anchoring piece welding direction is parallel to rotary kiln, so that the weak link of anchoring piece is back and forth stressed, also easily causes fractureing of anchoring piece.Whole kiln body inner lining refractory block is connected with flange by the groove of himself, and long-term operation adds the contraction of material when stopping kiln, can form brick-dropping, and then forms the ring-type slump, and is unfavorable to safety in production and equipment longevity.
Therefore, produce a kind of simple in structurely, easy to maintenance, simple to operate, can be connected with the kiln body and connect, reduce the external wall temperature of kiln, energy-saving and cost-reducing, be easy to produce, can improve the rotary kiln rotary kiln fire-resisting prefabricated brick in service life, have wide market prospects.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of simple in structure, easy to maintenance, operation simple and easyly is connected closely with the kiln body, the external wall temperature of kiln is low, save energy and reduce the cost, be easy to produce, the rotary kiln fire-resisting prefabricated brick of long service life.
The technical solution of the utility model is achieved in that a kind of rotary kiln fire-resisting prefabricated brick, comprise the preformed bricks body, described preformed bricks body is that cross section is the cuboid of isosceles trapezoid, the bottom surface of the preformed bricks body of this rectangular structure is arc, be respectively arranged with the first groove, the first flange, the second groove and the second flange at the upper surface of preformed bricks body and four faces between the lower surface, below the preformed bricks body, be provided with the bottom support seat, offer the anchoring hole clipping on the bottom support seat parallelled rotary kiln circumferencial direction.
Described the first groove is separately positioned on two corresponding faces of preformed bricks body with the first flange, and the second groove is separately positioned on two corresponding faces of preformed bricks body with the second flange.
Be provided with the first groove on the left surface of described preformed bricks body, be provided with the first flange on the right flank of preformed bricks body, be provided with the second groove on the leading flank of preformed bricks body, be provided with the second flange on the trailing flank of preformed bricks body.
Described bottom support seat is at least two, and is evenly distributed on the bottom surface of preformed bricks body, all offers the anchoring hole clipping on the both ends of the surface of each bottom support seat.
The utlity model has following good effect: the utility model preformed bricks body bottom arranges the bottom support seat, reserve the anchoring hole clipping at bottom support seat parallelled rotary kiln circumferencial direction, anchorage clip and anchoring hole clipping closely cooperate, and the preformed bricks body firmly is fixed on the rotary kiln barrel; The welding direction of anchorage clip is axially vertical with rotary kiln, so that anchoring piece contacts more firm with the kiln body; Leave arc the first groove, the first flange, the second groove and the second flange between circumference aspect preformed bricks body and the preformed bricks body, guarantee that the circumferencial direction preformed bricks becomes as a whole, anchorage clip does not substantially stress or is stressed less when rotary kiln rotates; Around the bottom support seat, fill out and establish thermal insulation layer, reduce the kiln outside wall temperature, energy-saving and cost-reducing; Use the utility model to build by laying bricks or stones conveniently, can significantly reduce the kiln outside wall temperature, improve the furnace equipment life-span.
