Description

Technical Field

[0001] The utility model belongs to the technical field of inspection and pre-assembly before installation of longitudinal seals and sealing angle irons of grate coolers, and particularly relates to various types of sealing composite inspection tools for CP grate coolers. Background Technique

[0002] The grate cooler is an important main equipment in the clinker burning system of a cement plant. Its main functions are to cool and convey cement clinker; at the same time, it provides hot air for the rotary kiln and decomposition furnace, etc., and is the main equipment for heat recovery in the burning system. The grate cooler is a type of quenching cooler. After the clinker enters the cooler from the kiln, it forms a layer of material with a certain thickness on the grate plate. The blown cold air passes through the moving material layer on the grate bed in a direction perpendicular to each other, enabling the clinker to be quenched rapidly. The clinker can be quenched from 1300 - 1400 °C to below 100 °C within a few minutes. The grate bed is the main component of the cooler, and the pushing grate plate is composed of fixed grate plates and movable grate plates arranged at intervals row by row.

[0003] In the existing situation, the longitudinal seal and the sealing angle iron, as the assembly gap for the refrigeration of the grate cooler, are key factors. However, they are manufactured separately, and the thickness of the surfacing layer and welding deformation are uncontrollable. If they are not inspected during separate manufacturing, it will result in failed products; the existing inspection tools cannot comprehensively utilize the mutual relationship among the longitudinal seal, the sealing angle iron, and the spring seal. Therefore, the utility model proposes various types of sealing composite inspection tools for CP grate coolers to solve the above problems. This tool not only inspects the gap between the longitudinal seal and the sealing angle iron, but also inspects the gap between the longitudinal seal and the grate cooler unit, making the shipping and on-site assembly worry-free, and this tool is universal for multiple models.
