Furnace door device with long service life and durable sealing

Abstract

The invention relates to a furnace door device with long service life and durable sealing. The furnace door device comprises a door locking device arranged between a furnace body and a furnace door. The furnace door device is characterized in that a position-variable self-adaptive balancing device is arranged between the furnace body and the furnace door, and the position-variable self-adaptive balancing device comprises a position-variable hinge device connected to the furnace door and a self-adaptive automatic guide positioner connected between the position-variable hinge device and the furnace body. The furnace door device with long service life and durable sealing is simple and reasonable in structure, convenient and easy to use and operate, good in sealing performance and effect and long in service life.

Description

technical field [0001] The invention relates to kilns, in particular to a long-life and durable sealed furnace door device for various kilns. Background technique [0002] The sealing reliability between the furnace door and the furnace body or the furnace mouth of the kiln including ceramics and other products is very important. If the seal fails, first, the heat consumption is large; second, the surface of the furnace body is hot, which affects the production environment. ; The third is other potential safety hazards. At present, the furnace 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 constant and cannot be adjusted during design and manufacture. During use, as the number of times the furnace door is opened increases, the thickness of the gasket becomes thinner after compression, and because one side is free and the other side Hinged, the un...

AI Technical Summary

Problems solved by technology

The gap between the fixed hinge and the furnace body is constant and cannot be adjusted during design and manufacture. During use, as the number of times the furnace door is opened increases, the thickness of the gasket becomes thinner after compression, and because one side is free and the other side Hinged, the unbalanced closing force of the furnace door not only affects both sides of the seal and the entire seal, but also causes inconsistent deformation, which further affects the seal of the furnace door. In order to ensure the sealing effect and make the closure tight, the free side of the furnace door is usually pressed tightly. , although this can make up for the thinning of the gasket, it cannot be compensated for at the fixed hinge, causing the gasket on this side to be unpressed, resulting in heat leakage and potential safety hazards, etc.

Generally, when such a situation occurs, the gasket can only be replaced as a whole, but the replacement is frequent; one is time-consuming and uneconomical; two, in case of negligence, it is easy to cause safety accidents
