Description

Technical Field

[0001] The utility model relates to the technical field of glass kilns, in particular to a heat preservation device for a glass kiln. Background Art

[0002] Industrial kilns are generally the most important production equipment for manufacturing companies. They are characterized by large scale, high heat consumption, and high pollutant emissions. For a typical glass kiln among industrial kilns, heat dissipation accounts for 28~30% of the total fuel consumption. Therefore, excellent thermal insulation is indispensable for glass kilns.

[0003] After exploration and analysis, the following shortcomings exist in actual use:

[0004] The existing technology mostly uses a layer of spraying aluminum silicate fiber cotton to achieve insulation in the kiln. After expansion cracks appear in the kiln, this material will directly come into contact with the open flame in the kiln. Due to its insufficient refractoriness and erosion resistance, it is easy to burn and fall on the liquid surface to form glass defects.

[0005] In summary, the present application proposes a glass furnace insulation device to solve the above-mentioned problems. Utility Model Content

[0017] Compared with the prior art, the beneficial effects of the present invention are:
