Abstract
The utility model provides a rotary cement kiln eye with long service life, which is characterized by additionally arranging a heat resistant steel sheath on the outer surface of a cylinder body at the position of a kiln eye of the existing rotary cement kiln. The heat resistant steel sheath is additionally arranged on the outer surface of the cylinder body at the position of the eye of the rotary cement kiln to protect the eye of the rotary cement kiln and increase strength thereof, thereby increasing high-temperature deformation resistant capacity of the kiln eye, and quadrupling the service life of the rotary cement kiln eye compared with the prior art. The rotary cement kiln eye is not only adaptable to process and manufacture of new rotary cement kiln eyes but also adaptable to maintenance, replacement and modification of old rotary cement kiln eyes.
Description
Technical field
The utility model relates to cement manufacture plant, is specifically related to the cement rotary kiln kiln mouth structure after a kind of improve.
Background technology
At present, the rotary kiln kilneye that cement industry uses, version is varied, and wherein having a kind of is the rotary kiln kilneye that kilneye cap iron is installed at rotary kiln kilneye place.The rotary kiln kilneye of this structure in process of production, often wash away because of high-temperature gas etch, high concentration dusty gas, intensity descends under the high temperature, very easily form horn mouth, and need maintenance to upgrade, generally be about 1-2 service life, exists shortcomings such as weak point in service life, time between overhauls(TBO) length, expense height, had a strong impact on the running efficiency and the Tai Shi production capacity of whole system equipment.How to prolong cement rotary kiln mouth service life, become one of key technology that national cement production enterprise emphasis captures in recent years.
Summary of the invention
The purpose of this utility model is to provide a kind of long-life cement rotary kiln kilneye.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of long-life cement rotary kiln kilneye, the barrel outer surface at existing rotary kiln kilneye place adds a heat resisting steel sheath.
The above-mentioned long-life cement rotary kiln kilneye that the utility model provides; because the barrel outer surface at rotary kiln kilneye place has added a heat resisting steel sheath; be used for protecting the intensity of rotary kiln kilneye and reinforcement kilneye; thereby improved kilneye high temperature deformation resistance ability, can make the rotary kiln kilneye reach more than 4 times of prior art service life.The utility model is not only applicable to the processing and manufacturing of new rotary kiln kilneye, is applicable to that also the maintenance of old rotary kiln kilneye is renovated.
Description of drawings
Fig. 1 is the structural representation of the utility model rotary kiln kilneye.
The specific embodiment
As shown in Figure 1, the long-life cement rotary kiln kilneye that the utility model provides, be that outer surface at the cylindrical shell 1 at existing rotary kiln kilneye place adds a heat resisting steel sheath 3, heat resisting steel sheath 3 welds together with the outer surface of cylinder of rotary kiln 1, and kilneye cap iron bolt hole 2 runs through cylinder of rotary kiln 1 and heat resisting steel sheath 3.
Above-described only is the utility model preferred embodiment.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, also should be considered as protection domain of the present utility model.
