Embodiment Construction

[0011] Such as figure 1 As shown, it is a sealed furnace door structure of the present invention, including a furnace body 1 and a furnace door 2 located at the port of the furnace body 1. The port of the furnace body is provided with a lifting mechanism for controlling the furnace door to move up and down. The lifting mechanism of the present invention is as follows: The furnace door rolling machine 31 shown in the figure, the upper roller 32, the lower roller 33 and the steel wire rope 34 are composed of a furnace door guide rail 4 on both sides of the port of the furnace body. The cooperation between the furnace door and the guide rail adopts a known common structure. This will not be described in detail. The furnace body below the furnace door is also provided with a furnace door base 5, the upper end of the furnace door base is provided with an inclined end face 51 that is high on the outside and low on the inside, and a roller 6 that cooperates with the inclined end face...

Abstract

The invention discloses a sealing furnace door structure, which comprises a furnace body and a furnace door arranged on the end opening part of the furnace body, wherein a lifting mechanism for controlling the furnace door to move up and down is arranged on the end opening part of the furnace body; furnace door guiding rails are arranged on both sides of the end opening part of the furnace body; a furnace door base is also arranged on the furnace body below the furnace door; an inclined end face of which the outside is high and the inside is low is arranged at the upper end of the furnace door base; and a roller matched with the inclined end face is arranged at the bottom of the furnace door. The sealing furnace door structure can solve the problem of poor sealing of the furnace door caused by discrepancy in the position of the furnace door due to the welding position of the roller, has a simple structure and runs stably and reliably.

Description

technical field [0001] The invention relates to a sealed furnace door structure. Background technique [0002] The up and down open sealed furnace door is used for heat preservation and sealing of industrial heat treatment furnaces during the heat treatment process. The traditional up and down opened sealed furnace door is mainly welded with rollers on both sides of the furnace door. The weight of the furnace door itself makes the furnace door drop and seal with the furnace body. Due to the offset of the welding position of the rollers in this structure, there is a gap between the furnace door and the furnace body after the furnace door is closed. vent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sealed furnace door structure, which can avoid the problem of poor sealing of the furnace door caused by the discrepancy between the position of the furnace door and the welding position of the rollers. [0004] ...
