Description
Technical field
The utility model relates generally to the roasting apparatus such as metallurgy, chemical industry, building materials, relates in particular to a kind of rotary kiln preformed bricks and rotary kiln liner.
Background technology
Rotary kiln, claims again rotary calcining kiln, is a kind of core industry main equipment, is widely used in the production industries such as building materials, metallurgy, chemical industry, environmental protection, and its principle is to utilize rotation and internal high temperature to carry out calcination processing to material in kiln, thereby forms finished product ore deposit.Rotary kiln is made up of kiln body, bracing or strutting arrangement and drive unit three parts, and wherein kiln body comprises kiln shell, kiln lining and burner three parts.Kiln lining is to build by laying bricks or stones and the refractory heat-insulating structure that forms by refractory material indefinite form powder cast-in-site or preformed bricks, the quality of kiln lining directly has influence on the radiation loss of rotary kiln, single ton of energy consumption, operating rate and service life, is the core in a whole set of rotary system.All the time insider be all devoted to seek better, stronger rotary kiln lining structure and material.
Apply on the market at present kiln lining structure more widely and mainly contain three kinds: brick material alternative expression as shown in Figure 1, pure fore shaft formula and the belt of many castables as shown in Figure 3 as shown in Figure 2.Above three kinds of kiln lining structures by indefinite form refractory matter cast-in-place be with 1 and preformed bricks 2 form, and preformed bricks 2 is the critical components that form rotary kiln liner, it and the cast-in-place difference with 1 of indefinite form refractory matter are its prefabricated baking moldings before dispatching from the factory, without on-the-spot formwork and baking and only need secure it on rotary kiln box hat by anchoring fastener, compare cast-in-site and shortened a large amount of construction periods.Prior art kiln body preformed bricks structure as shown in Figure 4, it builds installation diagram by laying bricks or stones as shown in Figure 5, preformed bricks 2 both sides are provided with draw-in groove 211, draw-in groove 211 links together adjacent preformed bricks 2 to form overall kiln lining by being arranged on anchorage clip 4 on kiln shell 3, in the time building by laying bricks or stones between brick and brick requirement should be as far as possible near, be reduced to minimum dimension by brickwork joint gap.There is following defect and deficiency in said structure: 1, existing rotary kiln liner working face is mainly preformed bricks 2, even if preformed bricks 2 machining accuracy in the time that it is built by laying bricks or stones is high again, site operation is accurate again, brickwork joint between brick and brick also can only ensure in 3～5mm left and right, when after the long-time production of rotary kiln, hot blast in kiln and thermal material very easily snap in brickwork joint, material snaps in and can make brickwork joint become larger and larger, hot blast enters the working environment that can worsen anchorage clip 4 under brick in brickwork joint, thereby make its operating temperature effect that makes its softening transform and then lose anchoring that raises, finally cause kiln body brick to come off accidents caused, hot blast also can burn kiln shell red formation " hot spot " phenomenon simultaneously, not only can shorten service life of equipment, and the radiation loss in kiln is significantly raise, energy consumption index significantly increases, 2, preformed bricks 2 wash away at the high temperature gas flow of the environment that works long hours, under material impact wearing and tearing, thereby its surface very easily produces to peel off and forms large pothole, these potholes are owing to there is no the anchoring of anchoring piece, be difficult to again it be poured into a mould to repairing, can only let alone to become larger and larger, finally cause this preformed bricks 2 to be cancelled.
