Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a secondary sealing device for the knife edge of a coking oven door. Background Technology

[0002] In the coking process, the sealing of the furnace door is crucial. The sealing structure of a coking furnace door consists of a knife edge installed on the door. Under external force, the knife edge makes rigid contact with the door frame to form a primary seal. With the increasing pursuit of higher efficiency and quality in coking production, there is a need for a device that can further improve the sealing performance of the furnace door. The coking furnace door knife edge secondary sealing device has emerged to meet this need.

[0003] In the existing technology, the secondary sealing device on the knife edge of the coking oven door is not easy to install and dismantle, and the operation is relatively complicated. When maintenance of the sealing components is required, it leads to increased time and labor costs, which in turn reduces the efficiency of installation, dismantling and maintenance.
