Description

Technical Field

[0001] The utility model relates to the technical field of boiler belt conveyors, in particular to a deviation correcting device for a boiler slag discharging belt conveyor. Background Art

[0002] After the slag is discharged from the boiler, the slag is mainly transported by a belt conveyor. When the belt conveyor is used for transportation, the belt should be in the center position, but it is easy to deviate during use, which is called belt deviation. The reasons for this phenomenon are as follows: 1. The active roller and the driven roller of the belt conveyor are offset, resulting in belt deviation; 2. The belt is loose, resulting in belt deviation; 3. The coal slag material is too heavy and unevenly distributed, resulting in belt deviation. For this, a more reasonable mechanical structure is currently used to avoid roller deviation, and a tensioning structure is used to make the belt tight to avoid belt deviation, but there are still the following defects:

[0003] A more reasonable mechanical structure is used to avoid roller deviation, and a tensioning structure is used to make the belt tight, which can prevent the active roller and the driven roller from deviating from each other and the belt from being loose. However, it still cannot solve the problem that the coal slag is too heavy and unevenly distributed, resulting in uneven force on both sides of the belt 22, which in turn causes deviation. Therefore, the deviation phenomenon is still relatively frequent when the belt conveyor is working, and it is not easy to correct after deviation. The belt needs to be moved manually, which is very troublesome.

[0004] For this reason, we propose a boiler slag conveyor deviation correction device to solve the above problems. Utility Model Content
