Abstract
The utility model discloses a carbon rotary kiln, and particularly relates to a precast block structure applicable to construction of the carbon rotary kiln. The precast block for the carbon rotary kiln comprises a heavy castable block and a light castable block, wherein a first groove is formed in the bottom of the heavy castable block, a first protrusion is arranged on the top of the light castable block, the first protrusion is embedded into the first groove in a matched mode, a third groove is formed in the bottom of the light castable block, and a ceramic fiber heat insulating plate is arranged in the third groove. According to the precast block, the strength of binding between the heavy castable block and the light castable block is high; due to the fact that the two materials make contact with each other first, breakage cannot easily happen, the structure is good in reliability, the service life of the precast block is long, and the service life of a liner of the carbon rotary kiln is prolonged.
Description
Technical field
The utility model relates to a kind of carbon rotary kiln, particularly relates to a kind of prefabricated section structure that is applicable to build by laying bricks or stones carbon rotary kiln.
Background technology
Rotary kiln is the key equipment in charcoal element production process, and its liner length service time directly has influence on the normal operation of the rear burnt production capacity of calcining and whole calcination process.Thereby to extend rotary kiln service life, avoid frequently changing liner belt, prefabricated section be the key structure of guaranteeing that castable liner can be used for more time.The existing rotary kiln prefabricated section of building by laying bricks or stones is to be connected and composed by castable viscosity by lightening casting material piece and heavy castable piece, lightening casting material piece and heavy castable piece bond strength are not high, easily at bi-material joining place, produce fracture, structural stability is poor, reduce the service life of prefabricated section, and then shortened the service life of liner.
Summary of the invention
The utility model is in order to solve the problems of the technologies described above, and provide a kind of carbon rotary kiln prefabricated section of building, heavy castable piece and the lightening casting material agllutination of this prefabricated section close slight height, bi-material first contacts and is not easy fracture, structural stability is strong, the service life of prefabricated section is upper, has extended the service life of inner liner of rotary kiln.
In order to solve the problems of the technologies described above, of the present utility model being achieved through the following technical solutions:
Carbon rotary kiln prefabricated section, it comprises heavy castable piece, lightening casting material piece, wherein heavy castable piece bottom offers the first groove, the top of lightening casting material piece is provided with the first projection, the first groove and the first projection match chimeric, the bottom of lightening casting material piece offers the 3rd groove, in the 3rd groove, is provided with ceramic fibre warming plate.
The first above-mentioned groove and the longitudinal cross-section of the first projection are rectangle.
Middle part one side of above-mentioned heavy castable piece offers half-cylindrical the second projection, in the equal height position, middle part of heavy castable piece, is provided with half-cylindrical the second groove, and half-cylindrical the second projection matches with half-cylindrical the second groove.
The second above-mentioned groove and the second projection are half cylindrical structure.
Longitudinal cross-section after above-mentioned heavy castable piece, lightening casting material agllutination closes is the trapezoidal of a sideband semi-cylindrical hill, the semicircle breach of another sideband.
Owing to adopting technique scheme, make the utlity model has following advantage and effect:
The utility model carbon rotary kiln prefabricated section, changed the structure of prefabricated section, in original heavy castable piece bottom, offering groove can combine with the bossing at lightening casting material piece top, and lightweight thermal insulation layer bottom is also provided with groove its ceramic fibre warming plate can be placed wherein.The utility model structure is compared with other traditional prefabricated section, has increased ceramic fibre warming plate, has improved the heat insulation effect of prefabricated section, with traditional prefabricated section, compares the service life that the utility model has strengthened structural stability and prefabricated section.The utility model prefabricated section monnolithic case is trapezoidal, lateral body has the half-cylindrical projection in one end, other end semi-cylindrical recesses, cylindrical the second projection and the combination that matches of half-cylindrical the second groove, prefabricated section in casting process can firmly be combined with castable, further strengthen liner resistance to overturning, simultaneously, the second projection and the second groove combine and can effectively slow down furnace high-temperature material and drop into lightweight thermal insulation layer, avoid high-temperature material to the destruction of heat-insulation layer and then avoided the too high phenomenon of kliner coating local temperature, further extended the service life of rotary kiln.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model.
Fig. 2 is the utility model side-looking structural representation.
In figure, 1, heavy castable piece, 2, lightening casting material piece, 3, ceramic fibre warming plate, the 4, first groove, the 5, first projection, the 6, second groove, the 7, second projection.
The specific embodiment
As depicted in figs. 1 and 2, the utility model carbon rotary kiln prefabricated section, it comprises heavy castable piece 1, lightening casting material piece 2, wherein heavy castable piece 1 bottom offers the first groove 4, the top of lightening casting material piece 2 is provided with the first projection 5, the first groove 4 and the first projection 5 match chimeric, the bottom of lightening casting material piece 2 offers the 3rd groove, in the 3rd groove, be provided with ceramic fibre warming plate 3, longitudinal cross-section the best of the 3rd groove is rectangle, middle part one side of heavy castable piece 1 is provided with half-cylindrical the second projection 7, in the equal height position, middle part of heavy castable piece 1, be provided with half-cylindrical the second groove 6, half-cylindrical the second projection 7 matches with half-cylindrical the second groove and can be entrenched togather with second groove of contiguous prefabricated, heavy castable piece 1, longitudinal cross-section after 2 combinations of lightening casting material piece is a sideband semi-cylindrical hill, the semicircle breach of another sideband trapezoidal.The best longitudinal cross-section of the first groove and the first projection is rectangle.
The size of prefabricated section can determine according to the size of specifically building liner by laying bricks or stones, and this is the very known general knowledge in this area, and the present embodiment is enumerated a kind of sized data of the best, but this can not be for limiting protection domain of the present utility model.The long 360mm of prefabricated section integral body, high 270mm, upper base 210mm, 260mm goes to the bottom, half-cylindrical the second protruding radius 12.5mm of side, provides the sized data of the first groove and the sized data of the 3rd groove below: the dark 30mm of the first bottom portion of groove groove, long 250mm, wide 130mm; The dark 10mm of the 3rd groove, long 250mm, wide 130mm; Ceramic fibre warming plate thickness 10mm.
