AI Technical Summary
Technical Problem
Existing extractors need to be shut down when adjusting the tension of the drag chain, which poses a risk of gas leakage. Especially in large-scale equipment, it is difficult to avoid mid-process shutdowns and gas leakage.
Method used
A closed chain tensioning mechanism is designed, which ensures sealing through the cooperation of the guard and the moving rod. A smooth rod is used to connect the guard with the thread to avoid gas leakage and achieve tension adjustment without stopping the machine.
Benefits of technology
This allows for adjustment of the drag chain tension without stopping the machine, thus avoiding gas leakage and improving the continuity and safety of equipment operation.

Abstract
The utility model provides a closed chain tensioning mechanism which comprises a tensioning shaft, an adjusting box and a moving rod, a guide block and a sliding seat moving along the guide block are arranged in the adjusting box, the moving rod is parallel to the guide block, the right end of the moving rod is arranged in a protective cover, the right end of the protective cover is a sealed end, the left end of the protective cover is connected with the adjusting box, and the right end of the protective cover is connected with the adjusting box. The left end of the moving rod penetrates through the adjusting box and is connected with the sliding base, the sliding base is driven by the moving rod to move along the guide block, the sliding base is rotationally connected with the end of the tensioning shaft, and the tensioning shaft is provided with a tensioning wheel matched with the chain. Through the matching of the shield and the moving rod, the sealing performance is ensured, the gas leakage is avoided, and the machine does not need to be stopped when the tension degree of the drag chain is adjusted.
