Improved brick structure for grate cooler parapet

Abstract

The invention discloses an improved brick structure for a grate cooler parapet. The improved brick structure for the grate cooler parapet comprises a brick body, side wing plates are arranged on the two sides of the brick body, the top faces of the side wing plates are flush with the top face of the brick body, the height of each side wing plate is half that of the brick body, the section of each side wing plate is in an L shape, two symmetrical positioning columns are arranged on the top face of the brick body, two symmetrical positioning holes are formed in the bottom face of the brick body, and when upper and lower adjacent bricks are fixed, the positioning columns are plugged into the positioning holes. Original heat resistant steel palladium nails and castable casting are omitted, prefabricated bricks are adopted to be directly laid, and meanwhile prefabricated bricks are connected more stably and accurately.

Description

technical field [0001] The invention relates to a kind of bricklaying, especially the bricklaying used for the low wall of grate cooler. Background technique [0002] The part of the low wall of the grate cooler is the most frequently damaged part of the cement kiln, and the replacement frequency is relatively fast. The refractory material in this part needs to withstand the abrasion of high hardness cement clinker for a long time, especially the grate cooler with uneven distribution of fine materials, which is quite worn. Therefore, the refractory material in this part needs to have high wear resistance; and the site pouring operation environment is harsh, and curing and baking cannot be guaranteed, resulting in poor wear resistance and erosion resistance of the wall, resulting in a short service life of the product; It is very difficult to dismantle castables for machine low walls, and the replacement area is large and the frequency is high. After dismantling, palladium n...

Therefore, the refractory material in this part needs to have high wear resistance; and the site pouring operation environment is harsh, and curing and baking cannot be guaranteed, resulting in poor wear resistance and erosion resistance of the wall, resulting in a short service life of the product; It is difficult to dismantle castables for machine low walls, and the replacement area is large and the frequency is high. After dismantling, palladium nails need to be re-welded, and then poured, cured, and baked, which is time-consuming and labor-intensive.
