Description
Technical Field
The invention relates to the field of glass machinery, in particular to a hole plugging structure of an annealing kiln.
Background
Annealing leys are one of the key devices in glass production lines that are directly related to the quality of the finished glass. The main functions of the annealing kiln are as follows: in the conveying process of the high-temperature glass belt through the roller way in the annealing kiln, the temperature of the glass belt is reduced to a normal temperature state according to a specified cooling curve, so that the permanent stress in the glass is reduced to a controllable range, and the subsequent processing treatments such as cutting and the like are facilitated.
The glass annealing furnace is a continuous annealing device, the shape of the glass annealing furnace is rectangular, and the length of the glass annealing furnace is 60-300m (the specific length is determined according to the process requirement); it establishes a stable temperature regime in the through direction from about 600 ℃ inside the annealing kiln inlet to about 50 ℃ outside the annealing kiln outlet. In general, the internal temperature of the heat-preserving zone of the annealing kiln, particularly the zone A, can reach 600 ℃, and the temperature of the external wall panel of the annealing kiln is required to be controlled below 75 ℃.
According to actual needs, the annealing furnace side wall is usually provided with an electric heating plug hole, an observation hole and a slag removal hole, and the conventional structure of the annealing furnace side wall plug hole and a plug body is shown in fig. 1. As can be seen from fig. 1, a plug hole is arranged between an outer side plate (i.e. an outer side plate of the annealing kiln) and an inner side plate of the side wall of the annealing kiln, a plug is matched in the plug hole, and heat-insulating cotton is filled between the inner side plate and the outer side plate around the plug hole; the plug holes are formed by directly connecting two circular holes with different pore diameters, namely, an outer plug hole with a larger diameter and an inner plug hole with a smaller diameter. Through long-term application, the plug hole itself forms a group of heat bridges directly connecting the inner side plate and the outer side plate of the side wall of the annealing kiln in actual use, so that heat conduction is greatly increased, and the temperature of the external wall plate near the plug hole is often higher than 100 ℃. Therefore, the traditional side wall hole plugging structure of the annealing kiln greatly increases heat dissipation, so that the temperature of the inner side part of the annealing kiln is too low, and the temperature stability is affected; meanwhile, the energy consumption in the production process of the annealing kiln is further increased, and the production is not good.
