Abstract
The utility model relates to the field of refractory materials in cement industry, in particular to a tertiary air pipe straight cylinder prefabricated part. The air pipe straight cylinder prefabricated part comprises a prefabricated brick body, wherein the prefabricated brick body has two types; according to one of the two types, the prefabricated brick body has a cone structure; and according to the other type, the prefabricated brick body has the cone structure, a conical raised head is formed on the small end surface of the cone structure, and the direction of conicity of the raised head is opposite to that of conicity of the prefabricated brick body. The tertiary air pipe straight cylinder prefabricated part is applicable to tertiary air pipe straight cylinder parts of new dry rotary cement kilns, directly built on a tertiary air pipe straight cylinder prefabricated part, convenient to construct and maintain, safe and reliable, and the construction period is greatly shortened; and simultaneously, the prefabricated brick body is made of steel fiber reinforced wear-resistant materials and can be used for more than four years actually, so that the service life is long, and the tertiary air pipe straight cylinder prefabricated part has high strength, high temperature resistance, wear resistance, a compact structure, high anti-stripping performance and relatively high thermal shock resistance, stability, and alkali erosion resistance.
Description
Technical field:
The utility model relates to the cement industry fire resisting material field, in particular, relates to a kind of tertiary-air pipe straight barrel prefabricated component, is applicable to new type nonaqueous cement rotary kiln tertiary-air pipe straight barrel position.
Background technology:
The selection of the refractory material of tertiary-air pipe straight barrel liner is the important step that improves the kiln lining life cycle, need the choose reasonable refractory material during design, reduce heat, mechanical stress that kiln lining bears, and reasonably select the brick type, reduce heat loss and strengthen the fastness that serves as a contrast body.The serious caustic corrosion under the high-temperature condition is not only born at tertiary-air pipe straight barrel position, but also will stand washing away of high speed tertiary air air-flow, and environmental working condition of living in is abominable, well damage, and usually impact is produced for this reason.Former design is generally high alumina castable or mullite corundum castable, and service time is short, and construction and maintenance are also very inconvenient, runs well for guaranteeing to produce, and must select suitable material to make the straight barrel liner.
The utility model content:
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of tertiary-air pipe straight barrel prefabricated component is provided, and adopts preformed bricks directly to build by laying bricks or stones, construction, and it is easy to maintenance, and is safe and reliable.
Technology solution of the present utility model is as follows:
Tertiary-air pipe straight barrel prefabricated component comprises the preformed bricks body, and described preformed bricks body has two kinds of structures, and the preformed bricks body of the first structure is vertebral body structure.
The preformed bricks body of the second structure is vertebral body structure, and is provided with a plush copper at the small end face of vertebral body structure.
In the technique scheme, described plush copper is the centrum shape, and the taper direction of plush copper is opposite with the taper direction of preformed bricks body.
The beneficial effects of the utility model are:
Preformed bricks of the present utility model is directly built by laying bricks or stones at tertiary-air pipe straight barrel position, and construction, easy to maintenance, safe and reliable has been shortened the construction period greatly.The material of preformed bricks of the present utility model is that steel fibre strengthens the High-Alumina wear-resistant castable, and reality was used greater than 4 years, long service life, its compact structure, high temperature resistant, wear-resistant, product has good anti-strip, preferably anti-thermal shock stability and alkali resistant erosiveness.
The utility model uses on distance kiln hood 8 ~ 10m tertiary-air pipe straight barrel, to adopt the bottom to strengthen compound High-Alumina abrasion-resistant prefabricated brick with the steel fibre of heat-insulation layer to build by laying bricks or stones, be that preformed bricks is composited by heavy working lining and light heat insulation layer, the brick surfacing, smooth, structure is fine and close, i.e. heat insulation again high temperature resistant airflow scouring, wearing and tearing.Working lining and thermal insulation layer do not break away from the use, and be not loosening, and long service life is built by laying bricks or stones conveniently, and operating efficiency has been improved in the time and labour saving.
The utility model and one deck calcium silicate board are used in conjunction with, and can build by laying bricks or stones at other positions of tertiary-air pipe straight barrel, have namely guaranteed the outer heat radiation of cylindrical shell, and less heat loss has satisfied again the allocation optimum of refractory material.The utility model can be made different structure, different size according to client's requirement simultaneously, satisfies client's demand.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
