Embodiment Construction

[0023] See figure 1 , figure 2 , image 3 , the adjustment method of the center line of the rotary kiln cylinder, the method includes the following steps:

[0024] 1. Coarse adjustment; connect the adjacent cylinders with bolts on the inner side of the cylinder, so that the connection ports of the adjacent cylinders are on the top;

[0025] 2. Fine adjustment;

[0026] 1) Mark the center line by the infrared measuring instrument, so that the center line of the cylinder body on the base seat of the active end and the base seat of the active end forms a line, and other cylinder bodies are adjusted based on this straight line;

[0027] 2) Adjust each cylinder by adjusting the crescent base 1, use the infrared measuring instrument 8 to measure the deviation between the center point of each cylinder and the reference line, and adjust each cylinder according to the deviation value, so that the two sides of each cylinder are The center points are all on the above reference line....

Abstract

The invention relates to an adjustment method for a center line of rotary kiln cylinders, which comprises the steps as follows: a bolt is in butting connection at the inner sides of the cylinders between adjacent cylinders so as to lead connectors of the adjacent cylinders to be centered; then (1) a center line is marked through an infrared measuring instrument to lead a driving end base seat and a cylinder center line on the driving end base seat to be a line, other cylinders take the line as reference for adjustment; and (2) each section of cylinder is adjusted through adjusting a crescent base, the deviation of a central point of each cylinder and the reference line is measured through the infrared measuring instrument, each section of cylinder is adjusted according to the deviation value so as to lead the central points at both sides of each section of cylinder to be on the reference line. Compared with the prior art, the adjustment method has the advantages that the method is used for high-altitude installation of the rotary kiln, the positioning and centering installation method is adopted, the hoisting centering is completed at one time, and the center line deviation of the rotary kiln cylinders is greatly reduced.

Description

technical field [0001] The invention relates to a method for adjusting the center line of a rotary kiln cylinder. Background technique [0002] The rotary kiln is a cylindrical object with a certain slope, and the slope is 3-3.5%. The rotation of the kiln promotes the stirring of the materials in the rotary kiln, so that the materials are mixed and contacted for reaction. The coal injection combustion at the kiln head generates a lot of heat, and the heat is transferred to the material by the radiation of the flame, the convection of the hot gas, and the conduction of the kiln brick (kiln skin). The material moves forward in the kiln depending on the inclination of the kiln cylinder and the rotation of the kiln. The installation of the rotary kiln includes: the installation of the rotary kiln cylinder, the installation of the transmission equipment, the installation of the idler group, the installation of the blocking roller, the installation of the large ring gear and the ...
