Description

Technical Field

[0001] The utility model relates to the technical field of boiler grate operation monitoring, in particular to a boiler grate operation monitoring device. Background Art

[0002] During the operation of the boiler grate, it is easy for the grate to get stuck with small stones mixed in the biomass, causing the grate to break. The volume of the biomass jujube shell is small. If the grate is damaged, the biomass will rely on the deadweight pressure of the biomass silo at the feeding port and quickly fall into the gap between the upper and lower grates. There is a lot of biomass accumulated in the grate interlayer. After the grate turns to the main shaft gear, the biomass pushes the grate to escape from the main shaft gear. When the grate load is large, the boiler grate reducer safety pin is broken, and the operator cannot find it in time. In just a few minutes, the boiler equipment will be damaged and the boiler will stop.

[0003] To this end, we propose a boiler grate operation monitoring device. Utility Model Content
