Abstract
The invention discloses an end sealing device for a sintering machine. The end sealing device is arranged in the position of a bellows adjacent to the head/tail end of the sintering machine. The end sealing device comprises a sealing bellows. The upper end of the sealing bellows is an open end. A flexible riser made of a flexible material is arranged at the upper end of the sealing bellows and extends in the circumferential direction of the upper end of the sealing bellows. The sealing bellows is connected with a pressure pipeline. The pressure pipeline is connected with a steam-jet pump which can generate negative pressure. When the steam-jet pump operates, negative pressure is generated in the position of the flexible riser of the sealing bellows, so that wind which leaks into the bellows at the head/tail end in advance is sucked into the sealing bellows, and effective sealing of the head/tail end of the sintering machine is achieved. Non-contact dynamic sealing is adopted by the end sealing device, and the defects that according to original contact type sealing, the maintenance amount is large, and the spare part cost is high are overcome.
