Problems solved by technology

[0003] 1. When the door panel moves up and down, the door panel shakes a lot, and it is easy to collide and generate sparks. This situation is very dangerous in the hydrogen protection furnace, and it is very easy to cause an explosion
[0004] 2. When the door panel moves up and down, the warehouse body will rub against the sealing strip on the door panel, which will greatly damage the sealing strip and easily cause defects such as poor sealing

Abstract

The invention discloses a gate device of an atmosphere protecting furnace, which comprises a door plate arranged on a doorway of a storehouse body; a guide rail mechanism is arranged between the door plate and the storehouse body for guiding the door plate to move upwards and downwards; the door plate is driven by a driving mechanism arranged above the storehouse body; and the door plate and the driving mechanism are connected by adopting a parallel four-link mechanism. As the parallel four-link mechanism is adopted in the connecting position between a cylinder or a hydraulic cylinder and the door plate, when the door plate moves upwards and the downwards, no obvious shaking is generated; collision does not occur; and explosion is not caused due to the generation of spark.

Description

technical field [0001] The present invention relates to a kiln, in particular to a kiln gate. Background technique [0002] In the prior art, the gate device of the kiln is driven by an air cylinder or a hydraulic cylinder to move the door plate up and down. When the door plate moves upward, the door opens and the saggar passes through; when the door plate moves downward, the door closes, thereby blocking the gas flow on both sides of the door plate (inside and outside the kiln). . However, this structure has the following drawbacks: [0003] 1. When the door panel moves up and down, the door panel shakes a lot, and it is easy to collide and generate sparks. This situation is very dangerous in the hydrogen protection furnace, and it is very easy to cause an explosion. [0004] 2. When the door panel moves up and down, the silo body and the sealing strip on the door panel will rub, which will cause great damage to the sealing strip and easily cause defects such as poor seal...
