Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning devices, in particular to a pipeline cleaning device for a grate cooler. Background Art

[0002] Grate cooler is an important main equipment in the clinker burning system of cement plant. Its main function is to cool and transport cement clinker. At the same time, it provides hot air for rotary kiln and decomposition furnace, and is the main equipment for heat recovery in the burning system. Grate cooler is a quenching cooler. After the clinker enters the cooler from the kiln, it is spread on the grate plate to form a material layer of a certain thickness. The cold air blown in passes through the moving material layer on the grate bed in a perpendicular direction to cool the clinker suddenly. The clinker can be cooled from 1300-1400℃ to below 100℃ in a few minutes. The air supply duct of the grate cooler needs to be cleaned after long-term use.

[0003] After searching the Chinese patent with publication number CN215864688U, a pipe cleaning device for a grate cooler is disclosed. By setting structures such as the No. 1 bevel gear, the No. 2 bevel gear and the No. 3 bevel gear, the rotation direction of the No. 2 rotating rod can be opposite to the rotation direction of the No. 1 rotating rod, so that the cleaning brushes on the outside of the No. 2 rotating rod and the No. 1 rotating rod rotate in opposite directions, thereby achieving a better cleaning effect of the cleaning brush. The setting adjustment mechanism can be used to adjust the position of the cleaning brush to adapt to pipes of different sizes. The setting fixed box, T-bar, spring and roller can provide a certain support effect, so that the power box is more stable during movement.

In the process of cleaning the pipeline, the pipeline is only cleaned by a cleaning brush, but the sewage formed after cleaning is still easy to stay and adhere to the inner wall of the pipeline. If there are too many impurities inside the pipeline, the impurities are not collected and processed separately, and the fallen impurities can easily cause blockage, which seriously affects the cleaning speed of the pipeline and reduces the cleaning efficiency of the pipeline.
