Abstract
The invention relates to a special prefabricated part for tertiary air duct bifurcation positions. The special prefabricated part comprises a first prefabricated block and a second prefabricated block obliquely fixed on the first prefabricated block, and the inclined angle between the first prefabricated block and the second prefabricated block is equal to those of the tertiary air duct bifurcation positions. The special prefabricated part for the tertiary air duct bifurcation positions has the advantages that the first prefabricated block and the second prefabricated block are sequentially stacked at the bifurcation positions of a tertiary air duct respectively, the special prefabricated part is short in production cycle, low in using cost and less prone to damage, service life is prolonged, and using effect of the tertiary air duct is improved.
Description
Technical field
The present invention relates to tertiary-air pipe fork position special precast spare.
Background technology
Prefabricated component is as new type nonaqueous cement rotary kiln field, solved not resistance to erosion of the original material of some privileged site (castable), critical problem easy to wear, tertiary-air pipe fork position special precast spare, mainly for containing A in the middle of the cement dry method rotary kiln, the designed prefabricated component of tertiary-air pipe in the two air channels of B, existing A, the tertiary-air pipe in the two air channels of B mainly forms by traditional castable cast, result of use is poor, retention cycle is short, long construction period, and integrated cost is high.
Summary of the invention
The existing tertiary-air pipe fork of the technical problem to be solved in the present invention position result of use is poor, and retention cycle is short, long construction period, and integrated cost is high, thereby tertiary-air pipe fork position special precast spare is provided.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: tertiary-air pipe fork position special precast spare, comprise the first prefabricated section, tilt to be fixed on the second prefabricated section on the first prefabricated section, described the first prefabricated section equates with the angle at tertiary-air pipe fork position with the angle that the second prefabricated section becomes.
Preferably, described the second prefabricated section becomes 10～80 ° with horizontal line, can adapt to the tertiary-air pipe in different two air channels, and result of use is good.
Preferably, the width of described the first prefabricated section equates with the width of the second prefabricated section, and result of use is good, and is simple in structure.
Preferably, the front end of described the first prefabricated section and the second prefabricated section is provided with groove, and is simple in structure, and result of use is good, has saved cost.
Preferably, a described prefabricated section and the second prefabricated section are wholely set, and save cost, and simple in structure, result of use is good.
Preferably, the bottom of described the first prefabricated section is provided with chamfering, and result of use is good, has protected the structure of prefabricated section, and is safe and reliable.
In sum, advantage of the present invention: by the first prefabricated section and the second prefabricated section respectively successively stack be arranged on the fork position of tertiary-air pipe, with short production cycle, use cost is low, and is not fragile, increased service life, improved the result of use of tertiary-air pipe.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the pre-tertiary-air pipe fork of the present invention position special precast spare.
The specific embodiment
As shown in Figure 1; tertiary-air pipe fork position special precast spare; comprise the first prefabricated section 1; tilt to be fixed on the second prefabricated section 2 on the first prefabricated section 1; described the first prefabricated section 1 equates with the angle at tertiary-air pipe fork position with the angle of 2 one-tenth of the second prefabricated sections; described the second prefabricated section 2 becomes 10～80 ° with horizontal line; the tertiary-air pipe that can adapt to different two air channels; result of use is good; the width of described the first prefabricated section 1 equates with the width of the second prefabricated section 2, and result of use is good, and is simple in structure; the front end of described the first prefabricated section 1 and the second prefabricated section 2 is provided with groove 3; simple in structure, result of use is good, has saved cost; a described prefabricated section 1 and the second prefabricated section 2 are wholely set; save cost, simple in structure, result of use is good; the bottom of described the first prefabricated section 1 is provided with chamfering 4; result of use is good, has protected the structure of prefabricated section, and is safe and reliable.
The first prefabricated section 1 and the second prefabricated section 2 are made through most advanced and sophisticated techniques such as press-molding, maintenance, baking, calcinings by high temperature resistant material, and appearance and size customizes in strict accordance with the actual conditions at tertiary-air pipe fork, then builds by laying bricks or stones by the scene to get final product.
By the first prefabricated section and the second prefabricated section respectively successively stack be arranged on the fork position of tertiary-air pipe, with short production cycle, use cost is low, and is not fragile, increased service life, improved the result of use of tertiary-air pipe.
