A construction method for building refractory bricks of a rotary kiln by using brick supporters

Abstract

The invention belongs to the technical field of laying methods for refractory bricks of rotary kilns, and particularly discloses a construction method for laying refractory bricks of a rotary kiln through a bricklaying supporting device. The construction method comprises the following construction steps that S1, the construction portion of the inner wall of a kiln shell of the rotary kiln is cleaned; S2, a plurality of longitudinal straight lines and circumferential lines are drawn on the inner wall of the kiln shell of the rotary kiln; S3, the bottoms of the refractory bricks are laid, namely the lower semicircles are laid; S4, the bricklaying supporting device is mounted; S5, the tops, namely the upper semicircles, of the refractory bricks are laid; S6, opening sealing and seam sealing work is prepared; S7, after sealing is completed, a lead screw is tightened, and the bricklaying supporting device is contracted, so that brickwork of the circle is made to automatically draw close to the center of the circular ring in a centralized mode; S8, seams in the brickwork and the inner wall of a cylinder are checked; S9, after the refractory bricks of the first circle are laid, the lead screw is tightened, and the bricklaying supporting device is contracted for withdrawing from the first circle; and S10, the steps from the step S3 to the step S9 are repeated for laying of the next circle. By the adoption of the construction method, quality accidents, such as falling and breaking of the refractory bricks, frequently occur during operation of the rotary kiln are avoided to a great extent.

Description

technical field [0001] The invention belongs to the technical field of masonry methods for refractory bricks of a rotary kiln, and in particular relates to a construction method for building refractory bricks of a rotary kiln by using a brick supporter. Background technique [0002] The commonly used masonry methods for rotary kiln refractory bricks generally include traditional kiln support masonry and bricklaying machine masonry. At present, the traditional kiln bracing method is generally used in China. The structure of the bricklaying machine itself is relatively complicated, the investment is relatively large, and its use is limited to a certain extent. It is mostly used in the masonry of large kiln diameters. [0003] Whether it is traditional kiln braced masonry or bricklayer masonry, these two construction methods have their own advantages and disadvantages. Kiln braced masonry is the easiest choice for small diameter kilns or partial refractory brick dismantling an...
