Embodiment Construction

[0053] A method for installing a rotary kiln for a large cement production line, comprising the following steps:

[0054] ①Foundation preparation and marking: Mark the rotary kiln shell divided into eight sections to be installed in sequence for future use, and then set the installation support points along the same straight line at the head, middle and tail of the rotary kiln at the site to be installed as the first kiln pier 1 , the second kiln pier 2 and the third kiln pier 3, that is, the first kiln pier corresponds to the eighth cylinder, the second kiln pier corresponds to the fifth cylinder, the third kiln pier corresponds to the second cylinder and the outside of the third kiln pier The kiln tail frame foundation 6 corresponds to the first shell; then the central axis 4 of the three kiln piers and the transverse centerline 5 of each kiln pier perpendicular to the central axis are marked (as figure 1 shown);

[0055] ② Hoisting of support roller groups: hoist the first...

Abstract

The invention discloses an installation method for a rotary kiln for a large-sized cement production line. The installation method comprises the following steps of 1, performing basic preparations and marking off; 2, hoisting riding wheel sets; 3, hoisting a first barrel; 4, hoisting a second barrel; 5, hoisting a third wheel belt; 6, sheathing a gearwheel; 7, hoisting a third barrel; 8, hoisting a fourth barrel; 9, hoisting a fifth barrel; and 10, hoisting a second wheel belt; hoisting a first wheel belt; hoisting a sixth barrel and a seventh barrel; hoisting an eighth barrel; enabling the first wheel belt to be in position; and installing a transmission device of the rotary kiln, an oil tube, a water tube and an air tube and performing test run. The installation method not only is simple but also is time-saving, and construction economic benefits can be directly provided.

Description

technical field [0001] The invention relates to a method for installing a rotary kiln for a large cement production line. Background technique [0002] The rotary kiln is the core equipment of the cement plant. Its structure is complex and heavy, and it must withstand the harsh environment of high altitude, high temperature and high load during production. In the installation and construction, its installation process is the most complicated, the difficulty is also the highest in the cement plant installation and construction, and the required site is also the largest. [0003] For large cement production lines, such as 10,000 tons / day cement production line, the diameter of the rotary kiln can reach meters, with a length of 92 meters, and its specifications are currently one of the largest cement plants in China. Because of its large size, the structure is more complex and requires higher precision. At the same time, the site requirements are also larger and it is diffic...
