Description

Technical Field

[0001] The utility model relates to the technical field of coal grates, in particular to a residual coal cleaning device for a coal grate. Background Art

[0002] Currently, power plants primarily use coal for electricity generation. Coal produced in coal mines is crushed and transported to power plants by train. A car dumper flips the train cars at a certain angle and unloads the coal into the coal bunker. Above the bunker, there are coal grates. Because the incoming coal may contain large lumps, wet coal, or sticky coal, these grates often become clogged, hindering unloading and, in severe cases, disrupting the normal coal supply to the power plant.

[0003] The inventors discovered that the existing technology has at least the following unresolved issues: Existing coal grates are typically cleaned manually using shovels, hoes, and other tools, requiring manual labor beneath a dumper. This creates a dusty, dark, and cramped work environment, presenting significant safety risks and slow cleaning efficiency. Furthermore, the single drum sweeping cleaning method cannot remove excess coal embedded in the grate grid holes, failing to completely resolve the grate clogging issue.

[0004] Therefore, we propose a residual coal cleaning device for a coal grate, which can solve the above problems. Utility Model Content
