Description

Technical Field

[0001] The utility model relates to the technical field of chain grates, in particular to a chain grater exhaust duct connecting device. Background Art

[0002] The chain grate is a crawler-type heat transfer equipment. In the pellet production process, the chain grate is responsible for the drying and preheating process. The direction of the high-temperature airflow in the chain grate is from bottom to top, from the blast drying section-exhaust drying section-preheating section I-preheating section II, and the highest temperature exceeds 1000°. The traditional pellet chain grate with a single-side exhaust system is affected by the single-side exhaust structure. The wind box end of the pellet chain grate has a too fast flow rate due to the change of wind direction and the vortex generated by the wind at the end of the wind box. The accessories used for pipe connection at the end of the wind box are quickly worn and burned, and frequent repair and maintenance are required, which affects the production progress and increases the cost of repair and maintenance.
