Installation method of rotary kiln

Abstract

The invention relates to cement production equipment installation, in particular to an installation method of a rotary kiln. The installation method comprises the following steps that S1, forming andbase installation are conducted; S2, riding wheel and retainer wheel installation is conducted; S3, a riding wheel position is adjusted, aligned and fixed; S4, barrel bodies is hoisted; S5, alignmentand welding of the barrel bodies are conducted; and S6, a transmission device is installed, aligned and fixed; the step S5 comprises the specific steps that S51, auxiliary calibration frames are correspondingly and fixedly arranged on the inner sides of barrel bodies; S52, the two ends of the barrel bodies are divided into nine equal parts in the circumference directions; S53, nine equal diversionpoints are sorted in sequence, every three groups of points are used as references to draw circles, three centers of the circles on calibration platesare used as references to draw circles, and center positions of the circles are recorded; S54,centre holesare formed in the centre positions of the barrel bodies; and S55, the barrel bodies are connected by bolts, and corrected by using a laser theodolite to ensure the centre holes on the calibration plates be in the same line, and the barrel bodies are welded later. According to the installation method, the effect of barrel body installation coaxiality is improved.

Description

technical field [0001] The invention relates to the installation of cement production equipment, in particular to an installation method of a rotary kiln. Background technique [0002] The rotary kiln is the most important production equipment in the cement powder production process. The installation accuracy of the rotary kiln will directly affect the service life and failure rate of the rotary kiln. [0003] The installation process of the existing rotary kiln includes the following steps: S1, install the forming base; S2, install the support wheel and the retaining wheel on the base; Secondary fixation; S4, hoisting of the cylinder of the rotary kiln, hoisting the rotary kiln above the supporting roller; S5, alignment and welding of the cylinder; S6, installation of the alignment transmission device. In step S5, the alignment of the cylinder is mainly the alignment of the coaxiality between the cylinders, that is, the alignment of the centerline of the cylinder. The cur...

Problems solved by technology

[0004] The disadvantage of the above-mentioned prior art is that, using the current method of aligning the coaxiality of the cylinder body, the operation is complicated, the measured data is more, and the time is long, and it is difficult to ensure absolute alignment after most cylinders are processed. Therefore, there is still a certain error after measuring the coaxiality. For the installation of small and medium-sized rotary kilns, it can meet the requirements of equipment installation, but for large-scale rotary kilns, it is difficult to meet the requirements of equipment installation, resulting in large-scale rotary kilns. There is always instability in the installation of the kiln
