Description

Durable sealed furnace door device with long service life

Technical Field

The invention relates to a kiln, in particular to a durable and sealed furnace door device with long service life for various kilns.

Background

The sealing reliability between a furnace door of a furnace for producing products such as ceramics and the like and a furnace body or a furnace opening of the furnace is important, and if the sealing fails, the heat consumption is large; secondly, the surface of the furnace body generates hot water, which affects the production environment; and thirdly, other potential safety hazards. At present, the oven door is generally connected by a fixed hinge on one side, and the free side on the other side can be opened and closed. The gap between the fixed hinge and the furnace body is invariable and unadjustable during design and manufacture, in the use process, along with the increase of the opening times of the furnace door, the thickness of the sealing gasket becomes thinner after compression, and because one side is in a free state and the other side is hinged, the closing stress of the furnace door is unbalanced, the sealing two sides and the whole sealing are affected, the deformation is inconsistent, the sealing of the furnace door is further affected, in order to ensure the sealing effect, the free side of the furnace door is usually tightly closed, so that the situation that the sealing gasket becomes thinner can be compensated, the fixed hinge cannot be compensated, the sealing gasket on the side is not tightly pressed, the leakage heat is generated, the potential safety hazard is caused, and the like. Generally, the sealing gasket can be replaced integrally, but the sealing gasket is replaced frequently; firstly, the method is time-consuming and uneconomical; and secondly, safety accidents are easy to happen in case of negligence.
