Modular filling method of side wall insulation cotton for lier

Abstract

The invention relates to the field of lier insulation, and in particular relates to a modular filling method of side wall insulation cotton for a lier. Massive experiments prove that the optimal insulation density of the insulation cotton is 170-180kg / m<3>, the insulation cotton thickness to be compressed can be converted according to the optimal insulation density, so that the insulation cotton can be used in the best insulation density; the kiln body frame structure is improved, an outer plate is separated from the kiln body frame, a sufficient space is provided, the insulation cotton is convenient to fill, a whole template is adopted for baiting and perforating, so that the size accuracy of each insulation cotton can be guaranteed, and occurrence of splicing gaps can be avoided; a special insulation cotton mounting and compressing tool is developed, has functions of dual-layer pressing, compressing insulation cotton and positioning of the side wall on the lier body frame, and is convenient to realize compression and mounting of the insulation cotton, so that the insulation effect of the side wall of the lier can be greatly improved.

Description

[technical field] [0001] The invention relates to the field of thermal insulation of a glass annealing kiln, in particular to a modular filling method for thermal insulation cotton on a side wall of a glass annealing kiln. [Background technique] [0002] The glass annealing furnace is one of the important equipments in the production of flat glass. Its main function is to cool the glass ribbon with a temperature as high as 600°C to about 70°C in a stable, continuous and controllable manner according to a certain temperature system, so as to obtain various indicators. Flat glass that meets the requirements of customers. According to the temperature curve during the annealing process of the glass ribbon, the annealing furnace is divided into a heat preservation zone and a non-heat preservation zone, and the temperatures are between 600°C~370°C and 370°C~70°C respectively. The heat preservation zone is the key zone for annealing in an annealing kiln, which is directly related ...

AI Technical Summary

Problems solved by technology

Because the insulation cotton is laid vertically, and its texture is relatively soft, it is prone to overturning; limited by the kiln frame structure, the operating space is narrow, so it is very difficult to fill the cotton, prone to voids, and the density cannot be compressed to the best use value

[0004] In addition, because there are many process operation holes on the side wall, affected by the frame column, each layer of insulation cotton can only be spliced ​​by multiple pieces, and there are a large number of splicing gaps. These reasons cause the existing annealing kiln side wall. The insulation is not good so it has to be improved
