Description

Grate plate tilting detection device of chain grate machine Technical Field The utility model relates to the technical field of chain grate machines, in particular to a device for detecting the tilting of a grate plate of a chain grate machine. Background The grate is an important device for bearing the drying and preheating procedures in the pellet production process. The working principle is that raw balls are uniformly distributed on a grate bed at the tail part of a chain grate, and the raw balls are heated by vertically penetrating through a material layer through gases with different temperatures through an air draft drying section and a preheating section in sequence, so that the dehydration, preheating and oxidation processes are completed. However, in actual operation, the grate plate of the grate may be tilted, which not only causes the shutdown and the shutdown of the grate, but also seriously affects the pellet yield and the pellet quality, and damages peripheral components due to the expansion of faults, thereby greatly increasing the maintenance cost and the maintenance time. Currently, many production plant monitoring mainly relies on manual inspection. The manual inspection has the defect that inspection personnel cannot monitor the running state of the tail part of the chain grate all-weather in real time, so that the development of the tilting of the grate plate of the chain grate is perceived in a serious stage, and the improvement is urgently needed. Disclosure of utility model The utility model aims to provide a grate plate raising detection device of a grate machine, which can detect the running state of the grate plate at the tail part of the grate machine in real time without manual inspection, improves the detection accuracy and prevents accidents from deteriorating.
